Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0025] Such as figure 1 , Figure 4 , Figure 5 As shown, the present invention is made of driving disc 1, driven disc 2, pressure plate 3, rivet 4, shock absorber 8 and spacer 9 etc., wherein driving disc 1 is a disc structure, and the middle part of driving disc 1 is provided with A through hole, one side of the through hole is integrally formed with a first annular boss 1a, and the inner hole of the first annular boss 1a is a spline hole. The disc body of the drive disc 1 is provided with five arc-shaped holes 1b uniformly distributed along the circumference, and the center of the circle where each arc-shaped bar hole 1b is located is on the axis of the drive disc 1 . On the disc body of the driving disc 1, five first positioning holes 5 are evenly distributed on the circumference. A small round hole 10 is opened at the corner, and the small round hole...

Abstract

The invention relates to a shock absorption coupler structure, which is characterized in that a first ring-shaped lug boss of a driving disc is sheathed with a pressure plate; the pressure plate, the driving disc and a driven disc are connected with each other by rivets uniformly distributed on the circumference; the driving disc can rotate an angle with respect to the driven disc and the pressure plate; the disc body on the driving disc is opened with first locating holes uniformly distributed on the circumference; the disc body of the driven disc is opened with second locating holes which are same in numbers, opposite in position with the first locating holes; the plate body of the pressure plate is also opened with third locating holes which are same in numbers and opposite in positionwith the first locating holes; the first locating holes, the second locating holes and the third locating holes on the same corresponding position form an accommodating space which is internally provided with a shock absorber. The shock absorption coupler structure can effectively absorb vibration energy generated during the working between an electrical motor and a speed changer, reduces the vibration of working conditions such as the starting, braking, anxious acceleration, anxious deceleration and the like, and avoids the damage of components and parts caused by impaction.

Description

technical field [0001] The invention relates to a connection mechanism for power transmission of a motor vehicle, in particular to a shock-absorbing coupling used in an electric vehicle. Background technique [0002] At present, new energy vehicles are becoming a development hotspot, especially the development of electric vehicles has become the focus of new energy vehicle development. Electric vehicles use electric motors as the drive powertrain, and the drive motor is connected to the transmission. If a simple rigid coupling is used, it is easy to generate vibration during vehicle starting, braking, rapid acceleration, rapid deceleration and other working conditions, which will affect the performance of the vehicle. . Therefore, there is a need for a coupling between the motor and the transmission that has excellent shock absorption performance and can effectively improve shocks to transmit motion and torque. Due to its own structural limitations, the traditional couplin...
