Abstract

The invention discloses a durability test device and a durability test system for a gear shift mechanism, and belongs to the technical field of gear shifting. The durability test device includes a first electric cylinder, a second electric cylinder, a PLC (programmable logic controller) and a first support, wherein a controller of the first electric cylinder is electrically connected with the PLC, and a controller of the second electric cylinder is electrically connected with the PLC; the fixed end of the first electric cylinder is fixed on the first support, and the movable end of the first electric cylinder is connected with the fixed end of the second electric cylinder, for controlling the second electric cylinder to move in the extending direction of the first electric cylinder; the movable end of the second electric cylinder is used for being connected with the control lever of the gear shift mechanism; the first electric cylinder is mutually perpendicular to the extending direction of the second electric cylinder. By using the durability test device and system, the gear shift mechanism with the complex gear shifting track can be tested.

Description

technical field [0001] The invention relates to the technical field of shifting, in particular to a durability test method and device for a shifting mechanism. Background technique [0002] With the development of shifting technology, shifting technology is more and more widely used in daily life. In order to check whether the quality of the shifting mechanism is qualified, it is necessary to conduct a durability test on the shifting mechanism after manufacturing the shifting mechanism. [0003] When people carry out the durability test of the shifting mechanism, they usually use a linear cylinder as the main test device, that is, two vertically placed linear cylinders are used to control the horizontal and vertical movement of the joystick of the shifting mechanism, thereby simulating Shift operation. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] In the shifting mech...
