Abstract

The invention discloses a parking mechanism endurance test device, comprising a gas source device, a loop control unit and a cylinder, wherein the cylinder is separated into a first chamber and a second chamber by a piston; the gas source device communicates with the first chamber via a first pipeline and communicates with the second chamber via a second pipeline; the telescopic rod of the cylinder extends out of the second chamber and is connected with the shift lever of the parking mechanism; the loop control unit is configured to control the communication or disconnection of the gas sourcedevice with the first chamber or the second chamber. According to the parking mechanism endurance test device, the cylinder drives the shift lever to perform reciprocating motion multiple times. Thus,the parking mechanism endurance test device can simulate the use of the shift lever after multiple operations to test the durability of the shift lever.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a parking mechanism durability testing device. Background technique [0002] The P gear, that is, the parking gear, its main function is to park the vehicle. The working principle is that when the shift lever of the parking gear is placed in this position, the gearbox is locked, which is similar to the fixed connection between the wheels and the body. Can't turn. [0003] Due to the frequent use of the parking gear, and the long-term parking, the shift lever needs to be hung up and removed continuously. After a long period of use, the shift lever in the gearbox may be excessively worn or fatigued. Case. Therefore, the durability of the shift lever of the parking mechanism is a factor that must be considered during the development of the gearbox. [0004] Therefore, it is necessary to provide a parking mechanism durability test device to detect the number of repeated...
