Embodiment Construction

[0052] The base of the hydraulic integrated unit is machined from LY12 duralumin. Firstly, use a deep hole drilling machine to process the pipes in the base body as required, and then process the cavity of each hydraulic component on the base body. During processing, select a suitable processing method to ensure the required surface roughness. Then start to install the various hydraulic components. Interference fit is used between the inverse proportional pressure valve, on-off valve, damper and low-pressure accumulator and the substrate to ensure its tightness. The substrate is heated first, and then each hydraulic component is loaded in sequence. The seal between the motor and the base is sealed with a sealant. A screw seal is used between the plunger pump and the substrate. In view of the structural requirements, the motor should be installed first, and then the plunger pump should be pressed in from both sides of the substrate at the same time.

Abstract

An integrated hydraulic control unit for the electronic stabilizing program of ABS in car features that two normally opened valves and two high-pressure normally dosed valves are arranged in 4 cavities at lower part of base, the 4 inverse-proportional pressure valves are arranged in 4 cavities at upper part of base, the plunger pump is arranged in the plunger pump cavity on said surface of base, the damper is arranged in the cavity on the rear side surface of base, the low-pressure energy accumulator is arranged in the cavity close to the cavity of damper, and the motor is on the top of base.

Description

technical field [0001] The invention relates to a control unit of an automobile anti-lock braking system. It is the application of hydraulic control technology in automobile control and belongs to the field of automobile comprehensive control. Background technique [0002] Automobile anti-lock braking system ABS for short, it starts from the passive safety of the car to improve the safety of the car when braking. The Electronic Stability Program (ESP) is referred to as ESP. It shares a hydraulic system with ABS, and from the perspective of active safety, it corrects the dangerous motion state of the car under certain extreme driving conditions. The combination of these two technologies forms a new integrated hydraulic control unit for automotive brake anti-lock braking systems and electronic stability programs, hereinafter referred to as the new integrated hydraulic control unit for automotive ABS / ESP. [0003] After a long period of development, the automotive ABS system ...
