The accelerator pedal of Zhongtong bus is very heavy. How to change it to light?

The accelerator pedal of Zhongtong bus is heavy or light, and the accelerator can be adjusted.

See if there is any jam in the rotation; You can add some oil to the throttle cable to make it more lubricated; You can also check the electronic accelerator of the car to see if the pedal is stuck. If it is stuck, please repair it in time. If the accelerator pedal is too heavy during driving, it will affect the driver's driving judgment; It may cause the throttle to be unable to make a good judgment.

At present, the reason why the accelerator pedal is overweight is probably because the spring under the accelerator pedal is too hard or too elastic. At this time, you can use the tool to pull the spring in the opposite direction, so that the spring force becomes smaller. If it is true that the accelerator pedal is too heavy due to excessive elastic force, the spring on the pedal can be removed, red-hot and cooled before installation, or the elastic force of the spring can be appropriately reduced.

Main functions of accelerator pedal

Control the opening of the throttle valve, thereby controlling the power output of the engine. The accelerator pedal of some cars is connected with the accelerator of the engine through the accelerator cable or pull rod, and the driver directly controls the accelerator when stepping on the accelerator pedal. Now many vehicles use electronic accelerator, and the accelerator pedal and accelerator are no longer connected by accelerator cable.

The accelerator pedal of the electronic accelerator is equipped with a displacement sensor. When the driver steps on the accelerator pedal, ECU will collect the opening change and acceleration of the displacement sensor on the pedal, judge the driver's driving intention according to the built-in algorithm, and then send corresponding control signals to the control motor of the engine accelerator, thus controlling the power output of the engine.
