Description

Drive device and vehicle

The present invention relates to a drive device for driving a vehicle, especially an electric motor device for driving a motor vehicle.

Such drive device is commonly used solely for driving the vehicle. The climate control of a vehicle interior is for example commonly realized by means of a separate climate control device, especially an air conditioning compressor device.

The present invention has the object to provide a driving device for driving a vehicle, especially a motor vehicle, with said driving device being compactly formed and by means of which a fluid may be compressible and/or drivable in an energy-efficient way.

This object is accomplished according to the present invention by the drive device comprising :

a drive motor for driving a driveshaft of the drive device;

a compressor device for compressing and/or driving a fluid,

the drive motor and the compressor device being arranged in a common housing of the drive device and wherein said drive motor and compressor device can be mechanically coupled to one another.

In this description as well as in the attached claims, the term "driving the vehicle" in particular refers to accelerating the vehicle for the purpose of initializing movement of the vehicle.

A fluid is in particular a gas and/or a liquid.

It may be desirable that the compressor device is formed as an air

conditioning compressor device. By means of such air conditioning compressor device, especially a cooling fluid may be compressed and/or driven.

The air conditioning compressor device is preferably used as a heat pump for providing heat and/or cold and/or for dehumidifying an airflow supplied into a vehicle interior.

It may be desirable for the drive device to comprise a coupling device by means of which the compressor device can be mechanically coupled to the drive motor.

In particular it can be provided that the drive device comprises a coupling device by means of which the compressor device can be detachably coupled to the drive motor.

In an inoperative position of the coupling device, the coupling device is preferably disengaged so that the drive motor is not mechanically coupled with the compressor device.

Especially by applying an electrical current to the coupling device, the coupling device may preferably be brought into an active position in which the coupling device is engaged. In said active position of the coupling device, the drive motor may preferably be mechanically coupled to the compressor device.

In one embodiment of the invention it can be provided that the drive device comprises an auxiliary motor which is, in particular permanently, mechanically coupled to the compressor device or can be, in particular permanently, mechanically coupled to the compressor device.

The auxiliary motor is in particular a motor different from the drive motor. Preferably the drive motor and the auxiliary motor are dimensioned such, that a maximum electrical power consumption, a maximum producible torque and/or a supplied maximum mechanical power of the drive device may exceed, e.g. at least twice, in particular at least five times, those of the auxiliary motor.

It can be provided that the compressor device, the drive motor and/or an auxiliary motor of the drive device may be arranged coaxially to each other.

In particular it can be provided that at least one rotating component of the compressor device, at least one rotating component of the drive motor and/or at least one rotating component of an auxiliary motor of the drive device may be rotatable around the same rotational axis.

The drive motor and/or an auxiliary motor of the drive device may preferably be formed as an electric motor.

Here it can be provided that a stator of the drive motor and a stator of the auxiliary motor of the drive device may be arranged non-rotatably and/or connected to each other non-rotatably at a common stator holder, especially the housing of the drive device.

The stators are in particular arranged coaxially to each other and may preferably have, at least approximately, the same outer dimensions and/or inner dimensions.

Further it can be provided that the stators may, at least approximately, have the same length or different lengths relative to a direction parallel to the rotational axis. Alternatively or in addition to this it can be provided that the stators, i.e. the stator of the auxiliary motor and the stator of the drive motor may have different outer dimensions and/or inner dimensions and/or different lengths.

It can be advantageous to establish a permanent non-rotatable connection between a rotor of the drive motor and the driveshaft of the drive device.

A rotor of the auxiliary motor of the drive device is preferably connected to a rotating component of the compressor device, especially to a compressor shaft, for driving the compressor device by means of a gear device of the drive device.

Said gear device preferably comprises a reduction gear and/or an epicyclic gear, especially a sun wheel driven epicyclic gear.

It can be provided that the compressor device comprises a swinging piston, a rotary piston and/or a rolling piston that is/are mechanically drivable by means of the drive motor and/or by means of an auxiliary motor of the drive device, especially for achieving a cyclical compression and/or cyclical drive of the fluid.

In one embodiment of the invention it is provided that the drive device comprises an auxiliary motor for driving the compressor device and that said auxiliary motor can be mechanically coupled to the drive motor to increase driving power of the drive motor.

In particular it can be provided that the driving device's mechanical driving power, which is provided exclusively by the drive motor when the drive device is in standard operation, may be increased temporarily by the auxiliary motor. It can be advantageous if the compressor device can be deactivated and/or short-circuited to increase the driving power of the drive motor. In this case preferably no energy is consumed from the auxiliary motor and/or the drive motor for compressing and/or driving the fluid.

For example, it can be provided that a fluid circuit of the compressor device, in particular the air conditioning compressor device, is short circuited to temporarily prevent undesired power consumption by the air conditioning compressor device.

According to the invention the drive device is particularly suitable for usage in a vehicle, especially a motor vehicle.

The present invention therefore also relates to a vehicle, especially a motor vehicle, comprising one or more drive devices according to the invention.

According to the invention the vehicle preferably comprises single or a plurality of features and/or advantages described in the context of the drive device.

It can be advantageous if the driveshaft of the drive device can be connected or is connected to at least one wheel of the vehicle, so the at least one wheel may be driven by the drive device and/or the drive device may be driven by the at least one wheel.

Especially for accelerating the vehicle, a torque can thus be exerted on the wheel preferably by the drive device. Further, preferably for decelerating the vehicle, especially for energy

recuperation, a torque can be transmitted from the wheel to the drive device. The drive device may then be used in particular as a generator device for generating electric energy, especially for recuperating electric energy.

The vehicle can in particular be a motor vehicle. Further the vehicle may be a utility vehicle, a processing machine, a military vehicle, and/or an aircraft.

According to the present invention the drive device is particularly suitable for usage in all kinds of electric vehicles with a demand for air conditioning, e.g. cars, trucks, trains, etc.

The drive device and/or the vehicle according to the invention may further preferably comprise individual or several ones of the following features and/or advantages:

The compressor device preferably comprises a swinging piston, especially a swinging piston element.

It can be desirable for the compressor device to comprise an eccentric element, with an eccentric outer shape relative to a rotational axis.

Preferably a piston element, especially a swinging piston element, of the compressor device is arranged at the eccentric element, especially in a manner so as to surrounding the eccentric element.

The piston element, especially the swinging piston element may preferably be moved for cyclic compression and/or cyclic driving of the fluid by the eccentric movement of the eccentric element during operation of the compressor device.

The compressor device is used in particular as an air conditioning compressor device. It may, however, also be provided that the compressor device is used for compressing and/or driving a different pneumatic or hydraulic fluid of a pneumatic device or hydraulic device respectively, required for operating the vehicle.

Preferably an auxiliary motor of the drive device can be activated or deactivated, especially depending on the operating status of the drive motor and/or the entire vehicle.

A drive device according to the present invention may preferably reduce costs of electric vehicles, especially by increasing the overall efficiency.

Compared to commonly known vehicles equipped with separate drive devices and air conditioning compressors, the number of components may preferably be reduced.

Especially with energy recuperation, the mechanical energy, transmitted via the wheels of the vehicle to the drive device, can be directly transferred to the compressor device, preferably in form of mechanical energy, for driving the latter.

A conversion of mechanical energy into electrical energy that, in turn, is used for driving a separate drive motor of a separate air conditioning compressor device, may thereby preferably be expendable. The available kinetic energy can therefore preferably be used more efficiently.

Compared to devices with a separate drive motor and a separate air conditioning compressor, the drive device in particular features a more compact structure, thus requiring less installation space in the vehicle and, in consequence, keeping the overall cost of the vehicle at a low level. Possible material saving may preferably result in advantages in logistics and an increased added value for the manufacturer of the drive device and/or the vehicle.

Application of the invention may advantageously result in increased overall efficiency in relation to all known driving cycles.

In case the drive device comprises an auxiliary motor, it is possible to drive the compressor device, especially the air conditioning compressor device to heat and/or cool the vehicle interior, even when the vehicle is stationary, especially when the drive motor is not running. Preferably the compressor device contains a rotary piston compressor having a high degree of efficiency.

The compressor device preferably further contains a sliding surface bearing for the revolving/rotating components, especially for the compressor shaft.

It may be desirable if the drive motor and/or the auxiliary motor are formed as permanent magnet energized and single tooth-wound synchronous machines, e.g. with a pole pair number of six and high utilization.

A gear arranged between the auxiliary motor and the compressor device is preferably an epicyclic gear where the input is provided by the sun gear and the output is provided by the planet carrier gear.

A coupling between the auxiliary motor and the drive motor may preferably be an electromagnetically operable, self-resetting coupling.

A shaft of the auxiliary motor and the driveshaft of the drive motor may preferably be arranged coaxially to each other.

It may be desirable if a shaft of the auxiliary motor and/or a compressor shaft of the compressor device surround(s) the driveshaft of the drive motor. Preferably the drive device is a liquid-cooled, especially water-cooled, overall system.

Further preferable features and/or advantages of the invention are referred to in below description and drawings of one embodiment.

FIG. 12 represents a schematic perspective view of the drive device in a nearly fully assembled state.

In the drawings, like or functionally equivalent references refer to the same parts throughout the different views.

Illustrated in FIGs 1 to 12 is a drive device, referred to generally as 100, as part of a vehicle referred to generally as 102, e.g. a motor car.

The drive device 100 comprises a drive motor 104, especially formed as an electric motor 106.

The drive motor 104 comprises a driveshaft 108, a stator 110, and a rotor 112.

The stator 110 is non-rotatably connected to a housing 114 of the driving device 100.

The rotor 112 of the drive motor 104 is non-rotatably connected to the driveshaft 108.

The driveshaft 108 and the thereto connected rotor 112 are rotatable relative to the housing 114 and the stator 110, especially arranged rotatable to each other.

The drive device 100 therefore in particular contains at least two bearing devices 116, e.g. ball bearings. The rotor 112 and the driveshaft 108 are in particular rotatable around a rotational axis 118 of the drive device 100.

Due to the drive motor 104 being an electric motor 106, a torque can be generated on the driveshaft 108 by applying electrical power, said torque being in particular transferable to the (not illustrated) wheels of the vehicle 102 for driving the vehicle 102.

Conversely, a torque, transmitted from the wheels of the vehicle 102 to the drive device 100, may be used for generating electric energy by means of the drive motor 104.

Thereby the drive motor 104 may also serve as a generator device.

Especially for air conditioning in an (not illustrated) interior of the vehicle 102, the vehicle 102 preferably comprises a compressor device 120, especially an air conditioning compressor device 122.

Shown especially in FIGs 4 to 6, the compressor device 120 is essentially discshaped, comprising two basic elements 124 laterally confining the compressor device 120 in an axial direction.

The basic elements 124 are formed such, that by means of the basic elements 124 in a mounted state thereof, a disc-shaped piston chamber 126 is being formed, in which a piston device 128 of the compressor device 120 is arranged.

The piston device 128 comprises an eccentric element 130 and a piston element 132. The eccentric element 130 is non-rotatably connected to a compressor shaft 134 of the compressor device 120 such, that the eccentric element 130 can be set in rotation by driving the compressor shaft 134.

The eccentric element 130 is formed with an eccentric circular outer shape relative to the rotational axis 118.

The piston element 132 is essentially formed circularly and has an inner diameter which essentially corresponds to the outer diameter of the eccentric element 130.

The piston element 132 is therefore arrangeable on the eccentric element 130 or in a manner so as to surround the eccentric element 130.

Due to the eccentric form of the eccentric element 130, the piston element 132 can be moved eccentrically around the rotational axis 118 during a movement of the eccentric element 130 around the rotational axis 118.

The piston element 132 comprises a holding fixture 136 for holding a valve device 138 of the compressor device 120.

The valve device 138 comprises in particular an essentially rectangular-shaped valve element 140, comprising an inlet 142 and an outlet 144.

In a mounted state of the compressor device 120, the valve element 140 protrudes through an opening 146, located in a piston chamber wall 148, formed by a basic element 124, of the piston chamber 126.

Further the valve element 140 comprises a valve spring element 150, by means of which a fluid connection between the inlet 142 and the outlet 144 of the valve element 140 may be blocked or released. Illustrated especially in FIGs 5 and 6, the valve element 140 may be subject to, e.g. a vertically directed cyclical up and down movement as well as a lateral tilting movement, as a result of a movement of the piston element 132 around the rotational axis 118.

To ensure a sealing function between the valve element 140 and the piston chamber wall 148 during said lateral tilting movement, the opening 146 is formed at least partially curved, in order to allow two stabilization elements 152, formed essentially complementary hereto, to be sealingly movable along the opening 146.

The valve element 140 is sealingly receivable between the stabilization elements 152.

The compressor device 120 further comprises an inlet opening 154 and an outlet opening 156.

Through the inlet opening 154 a fluid may be supplied to the compressor device 120. Said fluid can be compressed and/or driven by means of the compressor device 120 and may eventually be discharged through the outlet opening 156.

For the purpose of achieving a preferable low-vibration operation of the compressor device 120, the eccentric element 130, on the one hand, comprises a cavity 158 on one side, by means of which the mass of the eccentric element 130 is being reduced.

Further, a counterweight 160 is provided for the eccentric element 130 and/or the piston element 132 to minimize unbalance of the rotating parts of the compressor device 120. It can be provided that the compressor device 120 can be directly mechanically coupled to the drive motor 104.

In this case, an operation of the compressor device 120 would only be possible during simultaneous operation of the drive motor 104 of the drive device 100.

In order to realize operation of the compressor device 120 independent from the drive motor 104, the drive device 100 comprises an auxiliary motor 162, especially a compressor motor 164.

By means of the auxiliary motor 162, especially by means of the compressor motor 164, the compressor device 120 can preferably be driven independently form the drive motor 104.

The auxiliary motor 162 may also be formed as an electric motor 106.

The auxiliary motor 162 thus also comprises a stator 110 and a rotor 112.

The stator 110 is also preferably arranged non-rotatably at the housing 114 of the drive device 100.

The rotor 112 is preferably also rotatable around the rotational axis 118.

For connecting, especially for mechanically connecting or coupling the auxiliary motor 162 to the compressor device 120, the drive device 100 comprises a gear device 166 that, in particular, comprises an epicylic gear 168.

Illustrated especially in FIG 7, the gear device 166 is formed as a sun wheel driven gear.

The auxiliary motor 162, especially the rotor 112 of the auxiliary motor 162 is connected non-rotatably with a sun wheel 170 of the gear device 166. In the gear device 166 the output is further provided by a planet carrier. For this purpose, the compressor shaft 134 of the compressor device 120 is non- rotatably connected to a planet carrier 174 of the gear device 166.

An outer hollow wheel 176 of the gear device 166 is non-rotatably connected to the housing 114 of the drive device 100.

A rotating motion of the auxiliary motor 162 is thus transmittable to the compressor device 120 by means of the sun wheel 170, planet wheels 178 of the gear device 166, and the planet carrier 174, as well as by means of the outer hollow wheel 176.

The gear device 166 is especially a reduction gear, so a speed of the sun wheel 170 is higher than a speed of the planet carrier 174.

For example, a reduction between approximately two and three can be provided.

Especially it can be provided, that by means of the gear device 166 a speed of approximately 6000 revolutions per minute of the sun wheel 170 is reduced to a speed of approximately 2500 revolutions per minute of the planet carrier 174.

Due to the usage of the gear device 166 for connecting the auxiliary motor 162 to the compressor device 120, the connection between the auxiliary motor 162 and the compressor device 120 is a permanent connection.

As a consequence, a desired rotation of the piston device 128 around the rotational axis 118 will always involve a rotation of the rotor 112 of the auxiliary motor 162 around the rotational axis 118. The drive device 100 further comprises a coupling device 180, by means of which the drive motor 104 can be coupled mechanically to the auxiliary motor 162 and/or to the compressor device 120.

Illustrated especially in FIG. 8, the coupling device 180 therefore comprises a first coupling plate 182, arranged on the side of the auxiliary motor 162, and a second coupling plate 184, arranged on the side of the drive motor 104.

The first coupling plate 182 comprises a plurality of protrusions 186, by means of which said first coupling plate 182 is form locked, thus non-rotatably connected to the rotor 112 of the auxiliary motor 162 in a direction

perpendicular to the rotational axis 118.

For this purpose the rotor 112 comprises recesses 188, in which the

protrusions 186 are receivable.

The first coupling plate 182 is, at least to a minor degree, movable in a direction parallel to the rotational axis 118 relative to the rotor 112, especially for being engaged with the second coupling plate 184.

Despite this movability of the first coupling plate 182, the form locked connection between the first coupling plate 182 and the rotor 112 is preferably constantly maintained by means of the protrusions 186 and recesses 188.

The second coupling plate 184 is non-rotatably connected to the driveshaft 108 of the drive device 100 by means of a form-lock element 190.

Further, the second coupling plate 184 is fixed in axial direction, i.e. parallel to the rotational axis 118, relative to the driveshaft 108.

An anchor element 192, an electromagnet element 194, and an electromagnet housing 196 of the coupling device 180, are arranged on a side of the second coupling plate 184, facing away from the first coupling plate 182. The electromagnet element 194 and the electromagnet housing 196 are stationary, especially non-rotatably, fixed in axial direction to the housing 114 of the drive device 100 relative to the rotational axis 118.

The anchor element 192 is movably arranged in axial direction, i.e. parallel to the rotational axis 118.

In particular, the anchor element 192 is arranged at the first coupling plate 182 by means of a bearing device 116 and can be moved together with the first coupling plate 182 in axial direction.

The first coupling plate 182 and the anchor element 192 engage around the second coupling plate 184.

The anchor element 192 is, in particular, formed from a magnetic or

magnetizable material so that a force can be exerted on the anchor element 192 and the first coupling plate 182 attached therewith, by means of the electromagnet element 194.

In particular, the anchor element 192 can be pulled, together with the first coupling plate 182, in the direction of the electromagnet element 194 if an electric power is conducted through the electromagnet element 194.

The first coupling plate 182 can therefore be moved in the direction of the second coupling plate 184 and be engaged with the second coupling plate 184, especially be abutted on the second coupling plate 184.

During an activated state of the electromagnet element 194, the first coupling plate 182 is therefore coupled to the second coupling plate 184.

In this case, the auxiliary motor 162 and the drive motor 104 are mechanically connected to each other. As a consequence, a mechanical connection is established between the drive motor 104 and the compressor device 120 during an activated state of the electromagnet element 194.

The first coupling plate 182 is detached from the second coupling plate 184 when the electromagnet element 194 is deactivated.

In particular it can be provided, that the coupling device 180, for this purpose, comprises a plurality of spring elements 198 and a plurality of spring element holding fixtures 200, by means of which the coupling plates 182, 184 can be pushed apart when the electromagnet element 194 is deactivated.

As a consequence, the coupling between the drive motor 104 on the one hand, and the auxiliary motor 162 and the compressor device 120 on the other hand, is disengaged again.

Illustrated especially in FIGs 1, 11, and 12, the compressor device 120, the auxiliary motor 162, and the drive motor 104 of the drive device 100 are arranged in a common housing 114.

The drive device 100 is thus formed particularly compact.

In addition, the drive device 100 can use the available electrical and/or mechanical energy in a particularly efficient way.

Above mentioned drive device 100 in particular works as follows:

If used in a vehicle 102, the drive device 100 is used for operating the vehicle 102, especially accelerating the vehicle 102.

By means of the drive motor 104 a torque can be generated for this purpose, which may be transmitted to a (not illustrated) wheel or a plurality of wheels of the vehicle 102, by the driveshaft 108, for initializing movement of the vehicle 102.

Further the drive device 100 may be used, especially during a breaking operation for recuperating the kinetic energy of the vehicle 102, to transmit a torque from the wheel or from the wheels of the vehicle 102 by means of the driveshaft 108 to the drive motor 104, in order to use the drive motor 104 as a generator device and convert the introduced mechanical energy into electrical energy.

The electrical energy can then, in particular, be stored in a (not illustrated) battery device, especially an accumulator device.

The auxiliary motor 162 can, on the one hand, be used entirely independently from a driving state of the vehicle 102, in order to operate the compressor device 120.

In this case the coupling device 180 is deactivated so that no mechanical connection exists between the drive motor 104 and the auxiliary motor 162.

By means of the auxiliary motor 162, the compressor device 120 can then be operated as required, especially to cool, heat, and/or dehumidify the air to be supplied into the interior of a vehicle 102.

Further, if required or in order to optimize efficiency of the vehicle 102, a mechanical coupling may be established between the drive motor 104 and the auxiliary motor 162 by means of the coupling device 180.

The auxiliary motor 162 can e.g. be used to still further increase the torque generated by means of the drive motor 104 for driving the vehicle 102.

The auxiliary motor 162 can thus serve as a boost motor of the drive device 100. In this case, the compressor device 120 is deactivated by, e.g. short circuiting the fluid circuit of the compressor device 120, so that all available energy and power may be used to operate the vehicle 102.

Especially during a breaking operation of the vehicle 102, the torque

introduced via the wheels and the driveshaft 108 to the drive device 100 can be used to drive the compressor device 120 when the coupling device 180 is activated.

The compressor device 120 is therefore directly driven by using mechanical, especially kinetic energy. The electric energy reserves of the vehicle 102 are thus being saved despite operation of the compressor device 120.

By integrating the compressor device 120, the auxiliary motor 162, and the drive motor 104 into a common housing 114, and with the option of coupling the auxiliary motor 162 and the compressor device 120 to, on the one hand, the drive motor 104 and, on the other hand, to the coupling device 180, a particularly flexible reaction on various states of operation of the vehicle 102 is realized to ensure optimal usage of the available electric and/or kinetic energy.

The drive device 100 and, in consequence, the vehicle 102 are thus operable in a particularly energy-efficient way.
