Automobile brake performance testing device

Abstract

The invention provides a vehicle braking performance testing device, which effectively solves the problems of poor adaptability and high maintenance cost of the prior art, and is not suitable for maintenance of agricultural vehicles in rural areas; the technical solution is to include a casing , there is a U-shaped plate in the casing, a first gear is arranged in the U-shaped plate, a rotating shaft is arranged at the left and right ends of the central shaft, and there are runners on the rotating shaft; there is a first box on the rotating shaft, and a first oil pump on the first box; There is a roller on the top of the body, the roller is covered with paper, and there is a through groove on the upper side plate of the casing; there is a hydraulic cylinder in the cavity of the casing, and the two hydraulic cylinders are symmetrically arranged on the left and right, and the piston rod in the hydraulic cylinder is far away from the center of the casing. One side protrudes, and a marking pen is fixed on the end of the piston rod away from the center of the housing. The marking pen is vertically upward, and the tip of the marking pen penetrates the upper side plate of the housing and keeps in contact with the roller; there is a second gear in the U-shaped plate , there is a second oil pump on the U-shaped plate, and there is a liquid storage tank on the rear side of the housing cavity.

Description

technical field [0001] The invention relates to the technical field of automobile maintenance, in particular to an automobile braking performance testing device. Background technique [0002] my country is a large agricultural country, and agricultural machinery is widely used in farming areas. Brake failure is one of the most common failures of agricultural vehicles. The balance of agricultural vehicles is poor, especially for three-wheeled vehicles. If the braking force of the wheels on both sides is very different, it is prone to rollover and other dangers. At present, there are a large number of agricultural vehicles in the vast rural areas, including tricycles and tractors. Most of the time, they are not overhauled. The precision is too high, so basically there is no too fine equipment reserve for maintenance. Due to the above reasons, most of the maintenance points do not have the corresponding equipment for testing the balance of the braking force on both sides. If ...
