HPBHydraulic Power Brake Hydraulic Power Brake maintenance system and maintenance method

摘要

The present invention relates to a hydraulic power brake (HPB) maintenance system and a maintenance method. The present invention relates to a hydraulic pressure supply line and a hydraulic return line connected to a wheel cylinder of a brake assembly installed on a wheel for hydraulic pressure stored in a reservoir inside a vehicle, and an oil pump installed in the hydraulic supply line and operated by a motor, and in the oil pump A relay valve that opens the hydraulic pressure supply line when the brake pedal is operated by hydraulic pressure transmitted from an accumulator for storing the generated high pressure and a master cylinder having a brake fluid tank formed thereon, and installed between the relay valve and the wheel cylinder A hydraulic power brake (HPB) system comprising a supply solenoid valve and a return solenoid valve formed adjacent to and adjacent to the wheel cylinder, and a pressurizing device and a diagnostic device for servicing the HPB system.
