Description

Vibration damping device for automotive gearbox installed in series damping plate

technical field

The invention relates to an automobile transmission case, in particular to an automobile transmission vibration damping device installed in series with vibration damping plates.

Background technique

Automobile transmission (Transmission) is often called "gearbox" in automobiles; it is often called "speed changer" in industrial machinery, and it is a mechanical or hydraulic device for mechanical power conversion.

The transmission is one of the main components of the car transmission system. The actual use of the car is very complicated, such as starting, idling, low or high speed driving, acceleration, deceleration, climbing and reversing, etc., which requires that the driving force and speed of the car can be changed in a considerable range. The output torque and speed variation range of the adopted piston engine are small. In order to adapt to changing driving conditions and make the engine work under favorable conditions (higher power, lower fuel consumption), a transmission is installed in the transmission system.

Each gear has a different transmission ratio, which is equivalent to the meshing of the small gear and the large gear to produce different speeds. When driving at low speeds, use a low transmission ratio (3rd gear and below), and the speed of the large shaft is lower than the engine speed. According to the formula P =FV, can obtain greater driving force, use high transmission ratio (4th gear and above) at high speed, the rotation speed of the large shaft is higher than the engine speed, reduce the traction force to obtain higher speed, and select different sizes of gears and large shafts when switching gears. Shaft gear meshes.

Be that 2008201634752 in Chinese patent number, authorization announcement date be on June 19th, 2009, the patent document that title is called " a kind of automobile gearbox " discloses a kind of existing gearbox at once. The existing automobile gearboxes cannot meet the vibration damping requirements during use, and cannot be buffered in time when subjected to vibrations, resulting in damage to the connecting bolts and shortening the service life.

Contents of the invention

The invention provides a vibration damping device for a transmission case of an automobile installed in series with a vibration damping plate with multiple stages of vibration reduction, which solves the problem that the existing transmission case cannot meet the vibration reduction requirement when used.

The above technical problems are solved through the following technical solutions: a vibration damping device for automobile transmissions installed in series with damping plates, including a mounting plate and a beam, the mounting plate is provided with two supporting platforms, and the supporting platform is provided with a damping plate The vibration rod and at least two support rods, the mounting plate is provided with a vibration damping cylinder, the lower end of the support rod is installed in the vibration damping cylinder, the support rod is provided with an energy dissipation block, and the vibration damping cylinder The peripheral surface is provided with a first friction layer, the energy dissipation block is provided with a second friction layer, and the energy dissipation block is slidably connected to the In the damping cylinder, the damping rod is connected with an arc-shaped spring steel plate supported under the beam, and the beam is provided with a gearbox connecting frame. During use, the present invention realizes installation by connecting the mounting plate with the vehicle body, and the gearbox is connected to the gearbox connecting frame. When the present invention is subjected to the vibration of the vehicle, the friction between the first friction layer and the second friction layer firstly realizes the first-level vibration reduction, then the vibration-damping rod realizes the second-level vibration reduction, and then the arc-shaped spring steel plate deforms to absorb energy And achieve three levels of vibration reduction, so that the vibration transmitted to the gearbox is small to meet the vibration reduction requirements.

As a preference, the lower end of the support rod is provided with an adsorption structure, the adsorption structure includes a first suction cup connected with the support feet, a second suction cup is arranged in the first suction cup, and the first suction cup and the second suction cup An adsorption groove is enclosed between the suction cups, and the support rod is adsorbed in the damping cylinder through the adsorption structure. When assembling, by squeezing the first suction cup and the second suction cup at the same time, negative pressure is formed in the inner space of the first suction cup and the suction groove, that is, the support rod is fixed on the surface through the suction of the first suction cup and the second suction cup together. Inside the damping cylinder. When the absorption part of the first suction cup is temporarily disengaged due to vibration or instantaneous impact force, under the action of the second suction cup, the first suction cup will recover and perform adsorption after the instantaneous impact force disappears, so that the suction cup is instantly absorbed. There will be no shedding phenomenon when the local instantaneous disconnection occurs due to impact, and the decrease in the adsorption force will be small, that is, the good adsorption effect will still be maintained. The suction cup is used for installation and fixing, which improves the vibration reduction effect of the first-level vibration reduction, and is convenient for installation and disassembly.

Preferably, the suction end of the second suction cup protrudes from the suction end of the first suction cup. Because the first suction cup is located on the outside, it can be visually observed whether it is attached or not, but whether the second suction cup is attached or not cannot be visually seen, so if the first suction cup exceeds the second suction cup, there are the following shortcomings : If the pressing force is small, the second suction cup may not be adsorbed. In order to ensure the second suction cup is adsorbed, it needs to be pressed with a larger force. It is difficult to grasp the force and how long it lasts, which often leads to unnecessary Waste of effort and waste of time. In this technical solution, as long as the first suction cup is adsorbed, the second suction cup must be adsorbed, so that the second suction cup can be easily and quickly ensured to be adsorbed during assembly, which improves the convenience of assembly.

Preferably, a plurality of elastic connecting strips connecting the first suction cup and the second suction cup are arranged in the suction groove, and the elastic connecting strips are distributed along the circumferential direction of the second suction cup. When both the first suction cup and the second suction cup are adsorbed, the elastic connecting strip is elongated to store energy, and the energy produces a tendency to prompt the first suction cup to move toward the adsorbed object, so that when the first suction cup is momentarily disconnected, the acceleration The first sucker returns to the adsorption state. That is to say, the possibility of falling off when receiving an instant impact is further reduced, in other words, the ability of the suction cup to resist instant impact is improved.

Preferably, the connecting rod is provided with an air passage connecting the inner space of the second suction cup and the adsorption groove with the outer space of the first suction cup, and the outer end of the air passage is hinged with a seal for sealing the outer end of the air passage. build. When the sucker is extruded to absorb, the air in the sucker can push away the sealing cover and discharge, but the air pressure difference makes the sealing cover cover the outer end of the airway again when sucking. When the present invention needs to be moved, the inner space of the suction cup is vacuum broken by manually opening the sealing cover, so that it can be disassembled with a small force while ensuring a large suction force.

As a preference, the damping rod is a tubular structure, and several partitions are arranged inside the damping rod, and the partitions isolate the inside of the damping rod into a number of cavities distributed along the extending direction of the damping rod, so An elastic diaphragm is arranged in the cavity, and the elastic diaphragm divides the cavity into a filling cavity and an empty cavity. The elastic diaphragm is a bowl-shaped structure arched toward the filling cavity, and the filling cavity is filled with quicksand , the filling cavity is provided with a resistance increasing plate, which divides the filling cavity into a first filling cavity and a second filling cavity, and the resistance increasing plate is provided with a connection between the first filling cavity and the second filling cavity The friction hole of the cavity, and the empty cavity is provided with an air hole passing through the damping rod. When the vibration is generated, the damping rod is deformed, and the deformation of the damping rod causes the elastic diaphragm to deform and reset toward the empty cavity. At the same time, the quicksand flows back and forth between the first filling cavity and the second filling cavity, and the quicksand flows between each other. When the quicksand flows through the friction hole, it will rub against the friction hole and the friction between the quicksand will intensify, making the effect of vibration elimination and energy absorption more significant.

As a preference, the outer peripheral surface of the damping rod is provided with a number of shape-changing guide grooves distributed along the axial direction of the damping rod, and the inner peripheral surface of the vibration-damping rod is provided with a number of inner deformation guide grooves distributed along the axial direction of the damping rod , both the shape-changing guide groove and the inner-deformation guide groove are annular grooves extending along the circumferential direction of the damping rod. It is possible to improve the reliability when the damping rod drives the quicksand to flow when subjected to vibration.

Preferably, the shape deformation guide groove is aligned with the inner deformation guide groove. The vibration-damping rod can have good vibration-absorbing effect and rigidity.

The present invention also includes a spring steel plate elastic holding mechanism, which includes a swing gear, a forward drive gear, a reverse drive gear, a reversing gear meshed with the swing wheel, a power input shaft, two co-swing The gear meshes with the driven gear and two swing rods, one end of the two swing rods is connected with the two driven gears in one-to-one correspondence, and the other end of the two swing rods is provided with a A coating head correspondingly transmits heat to the two spring steel plates, the forward drive gear and the reverse drive gear are distributed along the axial direction of the power input shaft and connected with the power input shaft, the Both the forward drive gear and the reverse drive gear are sector gears, the forward drive gear is intermittently meshed with the swing gear, and the reverse drive gear is intermittently meshed with the reversing gear, so When the forward drive gear meshes with the swing gear, the reverse drive gear is disconnected from the reversing gear, and when the reverse drive gear meshes with the reversing gear, the forward drive gear The forward drive gear is disconnected from the swing gear, and the angle at which the forward drive gear drives the swing gear to rotate is equal to the angle at which the reverse drive gear drives the swing gear to rotate through the reversing gear. When in use, by giving heat to the coating head, the coating head will transfer the heat to the spring steel plate when the coating head swings back and forth along the stretching direction of the spring steel plate, so that the spring steel plate is kept in the required temperature range, thereby avoiding the spring’s elasticity caused by temperature changes produce changes. The motor driving the power input shaft does not need commutation, which facilitates the high-frequency swing of the pendulum.

Preferably, the coating head is ring-shaped, the coating head is sheathed on the spring steel plate, and a liquid flow channel extending along the circumference of the coating head is arranged inside the coating head, and the liquid flow channel The inner side wall is made of heat-conducting material. When in use, the hot water flows through the liquid flow channel, so as to realize the heat exchange between the water and the spring steel plate and realize the heat preservation of the spring steel plate.
