Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] Such as figure 1 As shown, the present invention is made of oil cylinder 1, outer spring 2, first piston 3, second piston 4, inner spring 5 and end cap 6, wherein oil cylinder 1 is a cylindrical structure with one end closed and the other open. The outer edge of the closed end extends outward to form a disc body. The first piston 3 is a cylindrical structure, the closed end of the first piston 3 protrudes into the oil cylinder 1 , and a throttle hole 3 a is opened on the closed end of the first piston 3 . The open end of the first piston 3 is sleeved on the annular boss in the middle of the end cover 6 , and the two are threadedly matched, and the end cover 6 seals the open end of the first piston 3 . Set outer spring 2 on oil cylinder 1 and first piston 3, one end of this outer spring 2 is limited by the disc body of oil cylinder 1 closed end outer ...

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...
