Description

FIELD OF TECHNOLOGY TO WHICH THE UTILITY MODEL RELATS

The utility model relates to a holder that provides the ability to transmit energy required for a system for measuring speed, temperature, torque, vibration and other related factors of a cardan shaft.

LEVEL OF TECHNOLOGY

Drive shafts are transmission components used in automotive vehicles to transfer rotational motion and energy generated in the engine or transmission to the vehicle's differential to provide movement of the vehicle.

Wireless power transmission technology is used to supply power to a circuit that is to be used to measure parameters such as temperature, torque and speed on a drive shaft.

The inductive wireless power transmission method is used, which is a wireless transmission method that uses the magnetic field between a pair of coils, called primary and secondary, to wirelessly transmit power from one coil to another without physical contact.

The primary coil must be located in a fixed position either on or outside the drive shaft, as it is supplied with constant power via a hardwired connection from a fixed source. The secondary coil is located on the drive shaft and is connected to the measuring circuit.

In the automotive industry, there are limited applications for electronic circuitry designed for measurement and data acquisition purposes that can be integrated with the driveshaft tube and continuously perform the desired tasks without requiring a change in the driveshaft design.

Application number TR2020/21509 shows a group of secondary coils integrated with the propeller shaft tube and a primary coil fixed to the vehicle chassis. During rotation of the propeller shaft, the position of the secondary coils changes and as a result the surface area facing the primary coil also changes. In a set of four or more coils on the secondary side, the power transmission drops to zero, especially at the nodal points, which causes an open circuit.

Patent number TR2017/08500 includes a wireless power transmission system and a measuring circuit integrated with a cardan shaft. However, the wireless power transmission in this system can only be achieved over a very short distance (1-2 mm), and the installation of the system requires a cardan shaft block called a “center bearing”. The primary coil is integrated with the shaft support block to achieve short-distance power transmission.

In the object of the utility model, wireless power transmission can be achieved on cardan shafts without the need for a block part called a "central bearing". Power transmission can be carried out over long distances (5-10 cm).

In addition, there are products similar to the utility model, but all of them require special design of the cardan shaft to integrate this electronic equipment. Other applications are experimental and test products that are disconnected from the cardan shaft after testing/experimentation and are not suitable for field work.

In addition, another disadvantage of all existing products is their high price. The product mentioned as a utility model object can be implemented without causing damage and can operate throughout the entire service life of the vehicle.

As a result, all the above mentioned problems have led to the need for improvement in the relevant field of technology.

OBJECTIVES OF THE UTILITY MODEL

The utility model is aimed at eliminating the above-mentioned problems and improving the relevant field of technology.

The main objective of the utility model is to provide a structure that can be adapted to a drive shaft tube, which can perform measurements such as temperature, rotation speed, torque, vibration, etc. on a vehicle, and which contains an electronic circuit and measuring equipment and can perform wireless transmission of electricity required for this measuring system.

Another purpose of the utility model is to eliminate power interruptions and prevent power losses during rotation of the cardan shaft.

Another object of the utility model is to provide a structure that enables continuous power transmission by providing a permanent connection to the drive shaft without disconnection, making it suitable for use in the field.

Another purpose of the utility model is to ensure the correct placement of the coils without causing any deformation on the cardan shaft.

Another objective of the utility model is to ensure long-term reliable operation in field conditions and under environmental influences without any modification of the design of the drive shaft.

Another purpose of the utility model is to ensure the correct position of the transmitter coils and to minimize transmission losses between the coils during rotation.

The utility model is a holder (30) that provides the ability to transmit energy required for a system that measures variables such as rotation speed, temperature, torque, vibration, etc. during inductive wireless power transmission by means of coils, and contains at least one plate of the primary coil located at a certain distance from the surface of the cardan shaft (20) of the holder (30), and wherein the holder (30) can be connected to the chassis (10), including: a holder (30) configured to be installed and removed without touching the cardan shaft (20), using at least one plate (401) of the primary coil, at least one fixing bracket (303) that connects the holder (30) to the chassis (10) for fastening the holder (30) at a certain distance from the surface of the cardan shaft (20); a characteristic lower main part (40) that provides an arrangement of the coil housings that provides inductive wireless power transmission between the primary coil on the surface of the holder (30) and the secondary coil on the surface of the cardan shaft (20); an inclined channel (403) in the lower main part (40) of the holder (30), which provides rotation of the second plate (402) of the primary coil around the x axis; a linear channel (404) in the lower main part (40) of the holder (30), which provides rotation of the first plate (401) of the primary coil around the y axis; an axial channel (51) in the lower main part (40) of the holder (30), which provides rotation of the first plate (401) of the primary coil around the z axis.

Fig. 1 shows the position of the primary coil housing (S1) and the secondary coil housing (S2), mounted on the chassis (10) by means of a holder (30), without contact with the cardan shaft (20).

Around the cardan shaft (20) are various parts of the chassis (10) of the vehicle. The chassis (10) shown in the figures can be provided in different ways, depending on the type and model of the vehicle, with the extensions shown accordingly. The utility model is mounted using fixing brackets (303) without damaging the connection point on the chassis (10).

Fig. 1A shows a secondary coil housing (S2) adapted to operate on a cardan shaft (20) and providing the ability to collect desired data associated with the cardan shaft (20). Although the position of the cardan shaft (20) changes during its movement, the solution of the arrangement using the first plate (401) of the primary coil and the second plate (402) of the primary coil to ensure the highest efficiency of power transmission depending on the position of the primary coil housing (S1), thus prevents power transmission losses and provides it with the ability to operate in the field.

Power is transmitted to the coil located on the body (S1) of the primary coil by means of the system and transferred to the coil located on the body (S2) of the secondary coil. Additionally, the electronic circuit located on the cardan shaft (20) performs the desired measurements using this power. Power supplied to the coil located on the body (S1) of the primary coil is wirelessly transferred to the secondary coils located on the body (S2) of the secondary coil by means of inductive methods.

The holder (30) is mounted on the chassis (10) by means of a fixing plate (301) attached to fixing brackets (303) and fixing screws (302). The moving channels (an inclined channel (403), a linear channel (404)) on the lower main part (40) are used to arrange the primary coils and the corresponding secondary coils to achieve the highest transmission efficiency; and they are fixed after assembly. In addition, these channels prevent interruptions in power transmission by arranging the first and second primary coils relative to each other.

The second plate (402) of the primary coil is equally affected by all changes in the location of the first plate (401) of the primary coil. In addition, the second plate (402) of the primary coil can independently perform movements with rotation along the x-axis. There is a mechanical design that ensures the possibility of arranging the plates of the primary coil relative to each other and performing precise adjustments, if necessary. Consequently, power losses are significantly reduced.

Fig. 4 shows a partial exploded view of the fixing brackets (303) of the lower main part (40). The design of the holder (30) provides the possibility of moving the primary coils along the x, y and z axes. There is an axial channel (51) providing the possibility of rotation along the z axis at the point where the fixing brackets (303) contact the body (S1) of the primary coil and the lower main part (40). There is a linear channel (404) providing movement along the y axis for fine adjustment, as well as rotation along the Z axis. The arrangement of the primary and secondary coils relative to each other is achieved by means of three degrees of freedom provided for the body (S1) of the primary coil, and the first plate (401) of the primary coil, as well as the second plate (402) of the primary coil.

The arrangement of the first plate (401) of the primary coil relative to the housing (S2) of the secondary coil is provided by a linear channel (404) and an axial channel (51) located on the surface of the first plate (401) of the primary coil, which is connected to the upper main part (50) on the surface of the lower main part (40).

The rotation along the x-axis is achieved by means of an inclined channel (403) designed perpendicular to the lower main part (40).
