Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to a gear shift cable durability testing device. Background Art

[0002] In manual transmission cars, the gear position is changed by the shift mechanism, and the gear position is changed by moving the gear lever to the specified position, and then the shift cable of the shift mechanism will drive the car's gearbox structure to change, thereby achieving speed change. Therefore, the shift cable needs to be used frequently in actual applications, and because the shift cable is closely related to the car's power system, its service life must be guaranteed, so it is very important to perform durability testing on the shift cable.

[0003] At present, the commonly used shift cable durability test device generally keeps the shift cable horizontal, fixes the sheath, and pulls the core wire to test the service life of the shift cable. However, in the actual vehicle, the shift cable is not laid out in a straight line, so when the shift cable is effective, there will be frequent friction between the core wire and the sheath, which makes the current test results different from the actual use results. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content
