Abstract

The invention relates to an automobile slide resistance detection device which mainly consists of a force measuring mechanism, a buffer damping mechanism, a buffer spring pressing groove steel frame mechanism, a straddling winch underframe mechanism, a pressing mechanism, and a zipper type secure pulling hook device. The invention mainly aims at resolving the problem that the slide resistance of automobiles is hard to be detected on the detection line; the detection device is installed in a braking bench to pull the automobiles in virtue of the braking bench, so that the detection system can fast and effectively detect the slide resistance of the automobiles, thus realizing the intelligent detection of slide resistance, enhancing detection efficiency, realizing multi-functionalization of the detection bench, and reducing the cost of detection equipment, and further guaranteeing the technical condition of the chassis, using the fuel more economically, and reducing discharge pollution; the indirect economical benefit is considerable, and the automobile slide resistance detection device is very favorable for economic development..

Description

technical field [0001] The invention relates to a detection device used in an automobile brake test bench, in particular to an automobile sliding resistance detection device which can be used in a detection line, and belongs to automobile performance detection equipment. Background technique [0002] The sliding performance of the car has a significant impact on the power and economy of the car. Therefore, the "Comprehensive Performance Requirements and Inspection Methods of Commercial Vehicles" has the inspection item of "vehicle sliding performance". Its technical requirements implement the GB 18565-2001 standard. In recent years, it has attracted extensive attention in the field of vehicle detection. In the previous testing of vehicle sliding performance, most of them are testing the vehicle's sliding distance, but the method is not economical and accurate enough. It is also possible to detect sliding resistance by manpower, or just to estimate the result, and the erro...
