Abstract

The invention discloses a motor-integrated electric control brake master cylinder driving system and aims at solving the problem that an existing hydraulic brake system is large in power-assisted volume and poor in active safety function and pedaling feeling during braking. The motor-integrated electric control brake master cylinder driving system comprises a brake pedal operating mechanism, a motor executing mechanism and a hydraulic control unit. The motor executing mechanism comprises a lead screw threaded rod mechanism, a stroke return mechanism, an input sealing mechanism, a housing mechanism, a lead screw threaded rod driving mechanism and a rotor position sensor. The stroke return mechanism is installed in a front end cover, the lead screw threaded rod mechanism is installed on the front end cover and a middle end cover through bearings and located in a rear end cover, the right end face of a stroke return spring rear seat of the stroke return mechanism is in contact with the left end face of a lead screw threaded rod in the lead screw threaded rod mechanism, a third-section shaft of a lead screw nut in the lead screw threaded rod mechanism is sleeved with the lead screw threaded rod driving mechanism, a first-section shaft of the lead screw nut is sleeved with the rotor position sensor, and the input sealing mechanism is installed in a first stepped blind hole of the lead screw threaded rod.

Description

technical field [0001] The invention relates to an integrated motor electric control brake master cylinder drive system in the technical field of automobile chassis. Background technique [0002] Since the birth of the automobile, the vehicle braking system has played a vital role in the safety of the vehicle. Modern automobiles generally adopt hydraulic braking system, which consists of brake pedal, brake master cylinder, vacuum booster, hydraulic pipeline, brake, etc. When braking, the driver depresses the brake pedal to push the brake master cylinder to move. The brake master cylinder converts the mechanical energy of the braking force input by the pedal into hydraulic energy, and the high-pressure brake fluid reaches the brake wheel cylinder through the hydraulic pipeline to achieve braking. However, the above-mentioned hydraulic braking system has certain shortcomings: the burden on the driver is relatively large; after integrating vacuum booster and active safety cont...
