Abstract

The invention discloses a magnetorheological fluid retarder performance testing device for a mini-type vehicle. The magnetorheological fluid retarder performance testing device for the mini-type vehicle is small in structural size, convenient to install and accurate in testing. The magnetorheological fluid retarder performance testing device for the mini-type vehicle comprises a vehicle frame and further comprises a braking inertia assembly and a testing system which are arranged on a left drive hub and a right drive hub respectively. A magnetorheological fluid retarder and a torque sensor of the testing system are arranged between a gearbox and a rear-axle transmission case in sequence from front to back, the front end of the magnetorheological fluid retarder is connected with an output shaft of the gearbox through a universal shaft, the front end of the torque sensor is connected with the rear end of the magnetorheological fluid retarder through a rigid coupling, and the rear end of the torque sensor is connected with an input shaft of the rear-axle transmission case through a rigid coupling. The magnetorheological fluid retarder performance testing device is suitable for a performance test of the magnetorheological fluid retarder for the vehicle.

Description

technical field [0001] The invention belongs to a vehicle retarder performance testing device, more specifically, relates to a miniature vehicle magneto-rheological fluid retarder performance testing device. Background technique [0002] Most of the vehicles will encounter relatively long slopes on the way. Under the circumstances that people's traffic safety awareness is lacking and the road conditions are very complicated, frequent braking of vehicles during normal driving is unavoidable. Aiming at the problem of vehicle braking safety, the current solution is to apply retarder vehicle technology with auxiliary braking effect while installing the original vehicle braking system. As the auxiliary brake of the automobile, the retarder is the key equipment to ensure the safety of the vehicle. At present, the electric eddy current retarder and the hydraulic retarder are mostly used in the retarder of the vehicle, which has a large structure size and high energy consumption. ...
