The invention discloses a novel full decoupling electronic hydraulic power-assisted
brake system, comprising a main power source, a pedal feeling
simulation mechanism, and a failure
backup operating mechanism which acts on a main cylinder. A motor of the main power source slows down through a worm and a wormwheel, and rotation motion of the motor is converted to translation of a rack through a gear and the rack. Through a first section spring A, a first section spring B, and a second section spring of the pedal feeling
simulation mechanism, pedal driving feeling is simulated. A failure protective jacket, a busing, and a locking sleeve of the failure
backup operating mechanism control movement of a
piston in the main cylinder, so as to act on a wheel
brake through a vehicle body stability
control system / anti-lock
braking system, so as to generate corresponding braking force. The
system has pedal
simulation modular design, providing convenience for realizing adjustable pedal feeling, and providing convenience for
system actual vehicle arrangement and maintenance. Combined with conventional ABS / ESC, active
brake, and
recovery of brake energy and failure protection are realized. The system is suitable to be used for blade electric vehicles and
hybrid vehicles.
