Abstract

The invention discloses a test device for a parking braking mechanism. The test device comprises a test bench, a parking brake adjusting support, a rotation adjusting bench, a force measuring device, and a drive device. The parking brake adjusting support fixed at the test bench is provided with a parking brake support frame and an inhaul cable support frame; a fixed end of a parking brake is arranged at the parking brake support frame; an inhaul cable assembly is arranged at the inhaul cable support frame; and the inhaul cable support frame is provided with a ranging sensor for measuring the inhaul cable assembly displacement. The rotation adjusting bench rotates relative to the test bench and is provided with a sleeve sleeving a handle end and a connecting rod for connecting the sleeve to the rotation adjusting bench. The force measuring device is arranged at the connecting rod. The drive device arranged at the test bench is connected with the rotation adjusting bench to drive the rotation adjusting bench to rotate. According to the test device, a parking braking force can be measured and the efficiency of the inhaul cable assembly can be calculated.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a testing device for a parking brake mechanism. Background technique [0002] In the related art, the test device for the parking brake mechanism is simply a device for testing the performance of the vehicle's parking brake mechanism. The measurement accuracy is not high, and it is only a simple test of the handbrake force. According to the test results, the parking cable assembly is adjusted in real time to match the correct installation position and method. Simultaneously, this test device can't solve the test of handbrake force, cable assembly efficiency and parking brake assembly fatigue at the same time. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention proposes a test device for a parking brake mechanism that can calculate the efficienc...
