Transmission shifting mechanism, shifting rocker arm and damping device for shifting rocker arm

Abstract

The invention relates to the technical field of vehicles, and provides a transmission shifting mechanism, a shifting rocker arm and a damping device for the shifting rocker arm. The damping device for the shifting rocker arm comprises a damping support and elastic damping blocks, a slideway which extends and is used for containing a protruding rod of the shifting rocker arm is formed in the damping support, the elastic damping blocks are arranged on the damping support so as to be used for pressing the protruding rod when the elastic damping blocks make contact with the protruding rod, and therefore the phenomenon that the shifting rocker arm and a shifting rod shake due to internal vibration of a transmission is significantly eliminated; the shifting feeling of transmission is correspondingly increased, and the situation that the transmission is failed in shifting is prevented.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vibration damping device for a gear shift rocker arm, a gear shift rocker used in conjunction with the vibration damper, and a transmission shift mechanism. Background technique [0002] It is known that the vehicle transmission changes the driving force and speed of the vehicle by changing the gear ratio, so as to ensure that the vehicle can run normally under various road conditions. With the continuous progress and development of automobile technology, there are more and more types of transmissions. However, the traditional manual transmission still occupies a major market share due to its simple structure, strong handling feeling and good fuel economy. [0003] In the manual transmission mechanism, the shift rocker arm is connected to the shift shaft of the transmission, a shift cable bracket is formed on the shift rocker arm, the shift cable bracket is connected with a s...

Problems solved by technology

[0004] However, in the actual operation of the vehicle, when the vehicle is idling or driving normally, the corresponding load excitation will be generated during the rotation of the transmission gear, and this load excitation will pass through the associated accessories such as the gear hub and tooth sleeve and shift fork connected to it. and transmitted to the shift rocker arm through the shift shaft, transmission housing and other components, and due to the assembly clearance and design factors of the shift rocker arm, the load excitation transmitted to the shift rocker arm usually causes shifting The vibration of the rocker arm, and this vibration will be amplified by the action of the counterweight of the shift rocker arm, making the shift rocker arm vibrate around the shift shaft, and then the vibration is transmitted to the shifter through the shift cable. The gear lever and the shift lever are vibrating, which affects driving comfort
