DEVELOPMENT TEST METHOD FOR HIGH-SPEED SWITCH VALVE OF AUTOMOBILE BRAKE SYSTEM

WIPO Patent Application WO/2021/104423

A1

Development test method and system for a high-speed switch valve (29) of an automobile brake system. A test tool (16) of the high-speed switch valve (29), an oil tank (1), and a temperature sensor (3) are fixedly mounted in a high-low temperature environment box (2); the oil tank (1) is connected to an inlet of a variable pump (12) by means of an inlet filter (13); an outlet of the variable pump (12) is connected to an inlet of the test tool (16) by means of a throttle valve (10); an overflow valve (14) and an energy accumulator (11) are connected and mounted on a pipeline between the throttle valve (10) and the outlet of the variable pump (12), a pressure sensor (9) and a flow sensor (15) are connected and mounted on a pipeline between the throttle valve (10) and the inlet of the test tool (16), and an outlet of the test tool (16) is connected back to the oil tank (1) after sequentially passing through a pneumatic ball valve (15) and an outlet filter (4). The development test method improves the flexibility of development and test of the high-speed switch valve (29), the test range is widened, and the test efficiency is high.
