Abstract

The invention discloses a valve body detection system of an automatic gearbox. The detection system comprises a pneumatic and hydraulic system, a measuring and control system and a platform, and boththe pneumatic and hydraulic system and the measuring and control system are arranged in the platform; the pneumatic and hydraulic system is composed of a hydraulic subsystem and a pneumatic subsystem,and is used to provide a pressure, flow and temperature controllable test medium; and the measuring and control system is used for parameter adjustment, data collection and processing and distribution protection of the pneumatic and hydraulic system; and an operation control panel is arranged on the platform, and used to adjust the oil liquid temperature, working pressure and flow. Via the detection system, the temperature range of the test medium is wider, and the measuring precision and system integration degree are high.

Description

technical field [0001] The invention relates to a transmission valve body detection technology, in particular to an automatic transmission valve body detection system. Background technique [0002] Automatic transmission valve body testing equipment (AT valve body test equipment, hereinafter referred to as valve body testing equipment) is used for automatic transmission parts, valve body and TEHCM performance testing. It provides oil with stable pressure, flow and temperature for valve body testing. The gearbox communication system (ETAS INCA) controls the solenoid valves of the gearbox, and the gearbox oil enters each oil passage respectively, and the ETAS data acquisition system records the pressure of each oil passage. The engine oil flows out after passing through the oil channel of the valve body, and can be recovered and filtered for recycling. [0003] The existing automatic transmission valve body detection equipment mainly has the following deficiencies: (1) the t...
