Shock absorption structure on electric car coupler

Abstract

A shock absorption structure on an electric car coupler comprises a cylinder, an outer spring, a first piston, a second piston, an inner spring and an end closure, wherein the first piston is tubular structure; the open end of the first piston is sealed by the end closure; the closed end of the first piston is sheathed into the cylinder, opened with a small throttling hole, is internally provided with the second piston and the inner spring; one end of the inner spring is butted with the second piston and the other end is butted with the end closure; the cylinder and the first piston are sheathed with the outer spring; one end of the outer spring is spaced by the closed end of the cylinder and the other end is spaced by the closed end. The invention causes that the couple has the shock absorption function while transmitting torsion, 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, avoids the damage of components and parts caused by impaction, and is characterized by clever conception, simple and reliable structure, excellent shock absorption performance, etc.

Description

technical field [0001] The invention relates to an electric vehicle, a shock absorbing structure used on the coupling of the electric vehicle, which is used for absorbing the vibration energy generated during the operation between the motor and the transmission. 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...

AI Technical Summary

Problems solved by technology

Due to its own structural limitations, the traditional coupling is difficult to meet the requirements of use. The coupling itself cannot absorb the vibration energy generated during the operation between the motor and the transmission, and the effect of improving vibration is limited.
