Abstract

The invention relates to a center component of an electronic brake booster capable of being mechanically and fully decoupled, and belongs to the field of vehicle braking. The gear is rotatably connected with the transmission nut, the transmission nut is in threaded connection with the screw assembly, the valve body component is in clearance fit and sliding connection with the screw assembly, the screw assembly is fixedly connected with the support through a buckle, a displacement sensor in the displacement sensor component is fixedly connected with the support, and a magnet of the valve body component is in clearance fit with the displacement sensor. The magnet and the displacement sensor slide relatively to generate relative displacement, and a displacement signal is generated and used for enabling the motor to act. The component has the advantages that the structure is novel, a failure mode caused by poor sealing can be avoided, a machine is used as a decoupling form, the reliability is higher, mechanical full decoupling can be realized, the booster brings greater endurance to a vehicle when the brake energy of the vehicle is recovered, and the booster is the development trend of a future service brake system.

Description

technical field [0001] The invention belongs to the field of automobile braking, in particular to a central component of an electronic brake booster capable of fully mechanically decoupling. Background technique [0002] In the past automotive electronic brake booster products, such as Bosch Ibooster and other products, a complete mechanical connection is used, and the driver's pedal is directly connected to the booster, and the booster is also mechanically connected to the brake master cylinder. This method leads to the inability of the brake booster to complete decoupling when the vehicle braking energy is recovered, so that the brake needs to cooperate with the ESC to recover the braking energy, resulting in poor braking feel and low recovery efficiency. [0003] The electronically controlled booster in the decoupling form currently on the market usually controls the opening and closing of the solenoid valve, and then performs full hydraulic decoupling, and the mode fails...
