The return of the braking pedal is usually achieved through a spring mechanism. When the driver releases the braking pedal, the spring mechanism acts to drive the pedal back to its original position. Different spring mechanisms have an obvious impact on the driving experience. The return force of the braking pedal on the market cannot be adjusted, which will bring different experiences to different drivers. Therefore, it is very important to develop a braking pedal mechanism with adjustable return force. Content of the Utility Model
