Abstract

The invention discloses a test device for the efficiency of a gear-shifting cable of an automobile. The test device comprises a test platform (7) and a data acquisition system, wherein the test platform (7) comprises a bracket (2) and a cylinder (1) fixed at the bottom of the bracket (2); an output rod of the cylinder (1) is connected with a tension force sensor (3); the other end of the tension force sensor (3) is connected with the head part of a gear-shifting cable (51); the other end of the gear-shifting cable (51) is fixed on a clamp (6); one end of the gear-shifting cable (52) is fixed on the side of the other end of the clamp (6); the other end of the gear-shifting cable (52) is connected with a tension force sensor (9); the tension force sensor (9) is connected with a spring (10); the other end of the spring (10) is fixed at the bottom of the bracket (2); and a displacement sensor (4) and a displacement sensor (8) are fixed on the bracket (2) respectively. The test device is simple in structure, convenient to install and disassemble, low in cost and capable of lightening the working intensity of test personnel.

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 gear position control mode of the transmission. The driver's action and the shifting mode action are connected by 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...
