Background

The braking system (also called as braking system) is mainly used for helping a driver to decelerate and even decelerate and stop the automobile in a driving state. At present, an electric control hydraulic power-assisted braking system is designed aiming at the braking characteristics of electric automobiles and new energy automobiles: when the driver steps on the brake pedal, the push rod is input to generate displacement, and the magnet support assembly moves along with the displacement. The pedal stroke sensor detects the displacement of the magnet and sends a displacement signal to the controller, the controller calculates the torque which should be generated by the motor, and the transmission device converts the torque into servo braking force. The servo braking force acts together with the input push rod force generated by the input of the pedal, and is converted into the hydraulic pressure of a brake wheel cylinder in the brake master cylinder together to realize braking. In the magnet bracket assembly of the electrically controlled hydraulic brake-assisted brake system, the magnet is usually held in the bracket body by a plastic member, however, the edge of the plastic member is liable to rub against the pipe wall during braking to generate undesirable noise.

Therefore, a need exists for a new magnet bracket assembly for a braking system.
