Problems solved by technology

The existing technical solutions mainly have the following disadvantages: the braking system of Honda hybrid vehicles uses dual brake master cylinders to realize the function, which has high cost and high requirements for the installation position; The corresponding functions can only be realized when used together, which limits the application of the product; Nason uses the empty stroke to realize the function of energy recovery, but when it fails, it will appear that the trample is too deep, causing users to panic

Abstract

The invention discloses an electronic power-assisted brake system. The electronic power-assisted braking system mainly comprises a braking main cylinder body, a braking main cylinder piston, an electromagnetic valve, a liquid storage cavity, an ECU controller, a motor, a gear, a box body, an output rod, an intermediate shaft, an upper cover, a push rod, an input rod, a shifting fork, a connectingrod, a nut, a lead screw, a bearing, a clamping ring, a key, a gear pair, a sensor, a sensor chip and a magnetic body. According to the invention, a brand-new energy recovery mode is realized, relatedbraking energy recovery can be carried out in cooperation with the whole vehicle without the support of an ESC, the cost is saved, the applicability of the product is improved, the energy recovery process is controllable, and the foot feeling consistency in the braking process under various conditions can be ensured.

Description

technical field [0001] The invention relates to the field of braking systems, in particular to an electronic power-assisted braking system. Background technique [0002] At present, the electric power assist systems used in the market mainly include: Honda hybrid vehicle brake system, which uses dual brake master cylinders to realize the function; Bosch uses ibooster+esc hev to realize; Realize braking energy recovery.
