Abstract

The invention relates to a P position test system used for an automatic gearbox. The system comprises: a fixing support, which is used to fix a tested automatic transmission; a P position control mechanism, which is used to control putting in and unlocking of the P position; a lever, which is fixed on an input terminal of the tested automatic transmission; a quality adjusting device; a hydraulic gear; a control apparatus and a P position detection part. The P position detection part is arranged in a P position of the tested automatic transmission and is used to detect the putting in and the unlocking of the P position. The other terminal of the lever is connected with the quality adjusting device which is arranged on the hydraulic gear. The control apparatus forms circuit connection respectively with the P position control mechanism, the hydraulic gear and the P position detection part. The invention also provides a P position test method used for the automatic gearbox. The P positiontest system used for the automatic gearbox of the invention is designed ingeniously. The system can be used for a performance and durability test of the P position of the automatic gearbox during parking on different ramp ways. The system is safe, accurate and reliable, possesses low costs and is suitable for large-scale application.

Description

technical field [0001] The invention relates to the technical field of automobile test devices and test methods, in particular to the technical field of automatic transmission test devices and test methods, and specifically refers to a P gear test system and test method for automatic transmissions, especially for automatic transmissions. The performance and durability test of gears when parking on different slopes. Background technique [0002] With the rapid development of the modern automobile industry, automatic transmissions are more and more widely used in automobiles. Compared with the traditional manual transmission, the automatic transmission has the following obvious advantages: (1) eliminates clutch operation and frequent shifting, makes the driver's operation simple and labor-saving, and improves driving safety; (2) can Automatically adapt to changes in vehicle driving resistance, realize stepless transmission within a certain range, and improve vehicle dynamics ...
