Automobile pedal stroke test device

Abstract

The invention relates to an automobile pedal stroke test device and belongs to the automobile performance detection device field. According to the automobile pedal stroke test device of the invention,the performance of an automobile pedal is tested with a steering wheel positioned. The automobile pedal stroke test device is provided with a steering wheel fixing sleeve which sleeves the steering wheel; the steering wheel fixing sleeve is connected with a steering wheel end hoop through a lockable universal connector; the steering wheel end hoop sleeves an outer sleeve; an inner telescopic rodis inserted into the outer sleeve; an end portion of the inner telescopic rod is sleeved with a clamping hoop; two folded edges of the clamping hoop are fastened through fastening bolts; the externalside of one of the folded edges is fixedly provided with a fixing sleeve; the fixing sleeve fixedly sleeves a center shaft; one end of a swing rod is in shafted connection with the center shaft; the other end of the swing rod is in shafted connection with a swing shaft; the extension portion of the swing shaft is in shafted connection with one end of a length fixed supporting rod; and the other end of the length fixed supporting rod is in shafted connection with the pedal through a pedal shaft. With the automobile pedal stroke test device of the invention adopted, the disadvantages of low measurement precision, large error, complicated installation, cumbersome operation, large required space, complicated operation, certain damage to a test vehicle caused by installation, and high technicalrequirements for testers can be eliminated.

Description

technical field [0001] The invention belongs to the field of automobile performance detection devices. Background technique [0002] The car pedal is one of the important parts for manipulating the car, and it can only be used if it meets a large number of performance tests. Among them, the pedal force and pedal travel are important indicators for evaluating the car's handling performance. [0003] Existing domestic and international detection automobile pedal stroke technology has the use of pulleys, the number of turns required to measure the number of pulley turns, the number of turns sensor, and the backguy to measure the pedal stroke; The pulley frame measures the pedal stroke; however, the automobile pedal performance test device in the prior art has the disadvantages of low measurement accuracy, large error, complicated installation, and cumbersome operation. [0004] In the existing domestic and foreign technologies for detecting the stroke of automobile pedals, the...

[0003] Existing domestic and international detection automobile pedal stroke technology has the use of pulleys, the number of turns required to measure the number of pulley turns, the number of turns sensor, and the backguy to measure the pedal stroke; The pulley frame measures the pedal stroke; however, the automobile pedal performance test device in the prior art has the disadvantages of low measurement accuracy, large error, complicated installation, and cumbersome operation.

[0004] In the current detection technology of automobile pedal stroke at home and abroad, there is also a wire-type displacement meter that needs a special fixture to measure the pedal stroke. However, the installation of this technical fixture will damage the test vehicle to a certain extent, and the space required is large, which is harmful to the testers. Disadvantages such as high technical requirements
