Abstract

The invention discloses a roller of a testing device of a motor vehicle. The roller structurally comprises a vibration sensor, a flywheel group, a driving roller, a lifting device, a driven roller, abody, an eddy current dynamometer, a gearbox, a speed sensor, and a coupling device, wherein the vibration sensor, the flywheel group, and the driving roller are installed behind the lifting device and are in mechanical connection, the body is internally provided with the eddy current dynamometer and is connected with the eddy current dynamometer by a bolt, a driven roller is arranged in front ofthe lifting device and is movably connected with the lifting device, and the dynamometer is fixedly arranged on the left side of the gearbox and is connected with the gearbox by a bolt. The vibrationtransducer disclosed by the invention is provided with wires, coils, housings, magnetic steel and elastic reeds and can be used for achieving the effect that an improved chassis dynamometer in the prior art is additionally provided with the vibration sensor for data testing of running shaking of a car, so as to avoid faults and car shaking from affecting the comfort of drivers driving at a high speed.

Description

technical field [0001] The invention relates to a roller of motor vehicle detection equipment, which belongs to the field of roller equipment. Background technique [0002] Chassis dynamometer is a kind of indoor bench test equipment used to test the performance of automobile power performance, multi-working condition emission index, fuel index, etc. The automobile chassis dynamometer simulates the road surface through the roller, calculates the road simulation equation, and uses the loading device Carry out simulation to realize accurate simulation of various working conditions of the car. It can be used for loading and debugging of cars, and diagnosis of car failures under load conditions; it is compatible with five-gas analyzers, transmission smoke meters, engine tachometers, and computers The automatic control system together forms a comprehensive measurement system to measure vehicle exhaust emissions under different working conditions. The chassis dynamometer is easy t...
