Abstract

The invention relates to a strength testing system of a speed changer shifting fork. The system is composed of an execution unit, data acquisition units, a working state simulation unit, and a data processing unit. A press machine is used as the execution unit. A displacement sensor and a pressure sensor are used as the data acquisition units. The working state simulation unit consists of a pedestal, a fixed guiding rod, a quickly-changed pressing head, an adjusting sleeve, pressing plates, a shift shaft, and a guiding sleeve. During testing, a speed changer shifting fork is installed on the shift shaft; the pressing plates are installed on two shift foot surfaces of the speed changer shifting fork; the pressure sensor is installed on the press machine and the pressing head is connected with the pressure sensor; and the press machine drives the pressing head to exert vertical pressing forces on the pressing plates. The pressure and displacement information generated during testing is connected with the data processing unit by the pressure sensor and the displacement sensor; and a data curve and a testing result are outputted in a microcomputer. According to the invention, the structure is simple and the design is reasonable; and the strength of the speed changer shifting fork can be measured accurately and conveniently.

Description

technical field [0001] The invention relates to the technical field of testing systems, in particular to a transmission shift fork strength testing system. Background technique [0002] At present, there is no quantifiable test method for the deformation of the transmission shift fork during the working process in China, and there is no quantifiable research data on the relationship between the deformation of the transmission shift fork and the performance of the transmission, that is, it is impossible to test the transmission shift. The strength of the shift fork. With the improvement of transmission users' requirements for product performance, it is necessary for transmission production units to conduct in-depth research on various factors that affect product performance. The correlation between transmission shift fork strength and transmission performance is also one of many research directions. Contents of the invention [0003] The purpose of the present invention i...
