Vehicle braking system and vehicle

Abstract

The invention discloses a vehicle braking system and a vehicle, wherein the vehicle braking system comprises: a brake push rod, an electric power assist system, an information collection system and an electric control system. The brake push rod is connected with the brake pedal; the electric booster system includes: a gear transmission assembly and a screw assembly, the gear transmission assembly and the screw assembly cooperate in transmission, and the gear transmission assembly is suitable for driving the translation of the screw assembly to push the brake The master cylinder piston in the master cylinder builds up the pressure to realize the braking of the vehicle, wherein at least a part of the gear transmission assembly is provided with a buffer structure to realize the buffer effect between the screw assembly and the gear transmission assembly. The moving gear transmission assembly in the electric booster system of the vehicle braking system is provided with a buffer structure, which can effectively avoid the collision between the screw assembly and the gear transmission assembly after the braking is completed, thereby effectively protecting the electric power booster. system, and can effectively avoid abnormal collision noise to improve the NVH performance of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a vehicle braking system and a vehicle. Background technique [0002] After the braking operation of the traditional vehicle electric braking system is completed, the screw assembly will quickly retreat. When returning to the initial position, the inertial screw assembly will collide with the gear transmission assembly, resulting in abnormal noise and impact Too much accumulation will cause damage to the screw assembly, thereby reducing the reliability and stability of the braking system, and there is room for improvement. Contents of the invention [0003] In view of this, the present invention aims to propose a vehicle braking system, which has better overall stability and does not produce abnormal collision noise, so as to improve the NVH performance of the vehicle. [0004] In order to achieve the above object, technical solution of the present invention is achieved in t...
