Abstract

The invention discloses a shift fork system test tool. The shift fork system test tool includes: a base, and a first bracket and a second bracket are arranged in a spaced manner on the base; a first cylinder sleeve fixing pipe is fixed on the first bracket and a first cylinder sleeve is fixed in a first accommodating cavity on the first cylinder sleeve fixing pipe; and a first cylinder sleeve cavity is arranged on the first cylinder sleeve, a first piston and the first cylinder sleeve cavity are matched slidably, and the first piston and a shift fork shaft are supported by each other; a firstoil channel joint is arranged on the first cylinder sleeve fixing pipe; a second cylinder sleeve fixing pipe is fixed on the second bracket, and a second cylinder sleeve is fixed in a second accommodating cavity on the second cylinder sleeve fixing pipe; and a second cylinder sleeve cavity is arranged on the second cylinder sleeve, and a second piston and the second cylinder sleeve cavity are matched slidably; and the second piston and the shift fork shaft are supported by each other; and a second oil channel joint is arranged on a second cylinder sleeve fixing pipe. Compared with the prior art, the shift fork system test tool in an embodiment of the invention can realize efficient detection of performance of a shift fork system.

Description

technical field [0001] The invention relates to the field of speed change shift fork detection, in particular to a shift fork system test tool. Background technique [0002] In the automatic transmission assembly, the shift fork system is the power mechanism to realize the shifting and downshifting of the whole machine. During the operation of the whole gearbox, it is necessary to continuously switch gears, resulting in the shift fork system being always in working condition. , in order to better verify the reliability and fatigue resistance of the shift fork system, it is necessary to conduct experimental research on the performance of the shift fork system such as movement displacement, shift force and oil impact position. [0003] In the prior art, the research on the reliability and fatigue resistance of the shift fork system is mainly carried out after the whole machine is installed. If the above performance research is carried out in the whole machine, it will take a l...
