Abstract

The invention discloses a test device for the efficiency of an automobile gear shift cable, which consists of a test bench (7) and a data acquisition system. The test bench (7) includes a bracket (2), which is fixed at the bottom of the bracket (2). cylinder (1), the output rod of the cylinder (1) is connected to the tension sensor (3), and the other end of the tension sensor (3) is connected to the head of the shift cable (51), and the shift The other end of the shifting cable (51) is fixed on the fixture (6); one end of the shifting cable (52) is fixed on the other end side of the fixture (6), and the other end is connected with the tension sensor (9). The sensor (9) is connected to the spring (10), and the other end of the spring (10) is fixed on the bottom of the support (2); the displacement sensor (4) and the displacement sensor (8) are respectively fixed on the support (2) . The test device of the present invention has the advantages of simple structure, convenient installation and disassembly, low cost, and can reduce the working intensity of testers.

Description

technical field [0001] The invention belongs to the technical field of auto parts testing, and in particular relates to an efficiency test device for an automobile shifting cable. Background technique [0002] The shifting cable of the car is used to select and change the transmission gear control mode, and the driver's action is connected with the action of the shifting mode through the mechanical action of the shifting cable. The shift cable connected between the throttle valve body and the gearbox determines when to shift gears by the opening of the throttle valve, and can also adjust the shift time of the gearbox by fine-tuning the length of the cable. The efficiency test of the shift cable also highlights its importance. [0003] At present, there are special test equipment for testing in China, and special test fixtures are used. The test device is not universal, which increases the test cycle and cost; for a long selection and shift cable, it will generally cause gre...
