Abstract

The invention relates to a performance test system for an HCU (hydraulic control unit) in an automobile brake system and belongs to the technical field of quality detection of automobile chassis dynamically-controlled parts. The test system comprises a pressure lifting device, a hydraulic pipeline system, a measurement control device and an environmental simulation device, and all parts of the test system are connected through pipelines. By means of the performance test system for the HCU in the automobile brake system, parameters such as the response speed and the sealing performance of an HCU valve, the flow and the pressurizing capacity of a plunger pump, the volume of an energy accumulator and the like can be tested accurately.

Description

technical field [0001] The invention relates to a performance test system of a hydraulic control unit in an automobile braking system, which belongs to the technical field of component quality detection of automobile chassis dynamics control. Background technique [0002] In order to improve vehicle performance, modern vehicles are equipped with Electronic Stability Control (ESC) and Anti-lock Brake System (ABS), among which Hydraulic Control Unit (hereinafter referred to as HCU) is the most important functional actuator of these two systems. The hydraulic control unit (HCU) is assembled by connecting high-speed switching solenoid valves, plunger pumps and accumulators. Among them, the response speed and tightness of the high-speed switching solenoid valve, the oil pumping capacity of the plunger pump, and the volume of the accumulator are indicators for evaluating the operating performance of the hydraulic control unit (HCU). It is of great significance to conduct a compre...
