Abstract
The utility model provides a gear shifting pulling wire damper in order to reduce noise and vibration of an automobile speed changer or prevent the noise and the vibration from being transmitted to a cab through a gear shifting pulling wire, and the NVH performance of an automobile is improved. The gear shifting pulling wire damper comprises a cylinder-shaped shell body and two independent elastic damping blocks which are arranged in the shell body. Through holes which are used for the gear shifting pulling wire to penetrate through are formed in the two ends of the shell body. Bosses used for preventing the damping blocks from falling out are arranged on the edges of the through holes. During a gear shifting process, when the gear shifting pulling wire at one end of the gear shifting pulling wire damper needs to transmit pushing force or pulling force, one damping block needs to be pulled or pressed, elastic deformation of the two damping blocks reaches a certain degree through the damping block or the shell body, and the pushing force or the pulling force can be transmitted to the gear shifting pulling wire at the other end. Due to the fact that the noise and the vibration of the speed changer cannot make both of the two damping blocks generate large deformation, the noise and the vibration cannot be transmitted through the two damping blocks, and accordingly partitioning of the noise and the vibration is achieved.
