What is the reason for the pedal shaking at startup but running smoothly afterwards?
1 Answers
The reasons for the pedal shaking at startup are as follows: 1. Belt: The trembling phenomenon when a motorcycle starts or at low speed is largely due to the long-term dynamic friction between the shoe blocks of the rear clutch plate and the housing in the belt box. 2. Slipping: The surface of the shoe blocks is contaminated by friction powder or dust from the air inlet in front of the belt box, reducing the friction between the shoe blocks and the housing, thus causing slipping. At this time, the vehicle will have a trembling sensation when starting or at low speed. 3. Reason for no shaking at startup: The reason why the vehicle shakes at startup or low speed but not at high speed is that the load at startup is much greater than the load at high speed, and the maximum static friction of the same object is greater than the maximum dynamic friction.
