Embodiment Construction
[0033] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0034] refer to Figure 1 to Figure 12 , The vehicle bench brake force detection wheel restraint device is composed of a restraint roller mechanism B, a lifting hydraulic system C, and a positioning hydraulic system D. The lifting hydraulic system C constrains the movement of the roller mechanism B in the vertical direction, and the positioning hydraulic system D completes the restriction of the movement of the roller mechanism B in the horizontal direction. The bottom surface of the lifting hydraulic system C is installed lower than the bottom surface of the positioning hydraulic system D, and the lifting hydraulic system C and the positioning hydraulic system D are connected in a "herringbone" shape.
[0035] The constrained roller mechanism B is composed of a constrained roller 1 , a roller end cover 2 , a roller shaft 3 , a roller bushing 4 , an outer spherica...

The invention discloses an assistant device for automobile detection equipment in the industrial field of automobiles, and in particular relates to a wheel constraining device for detecting braking force of an automobile rack. The invention aims to solve the problem that the braking force detection error is great because the detected automobile is in an unstable state in braking force detection of existing automobile rack. The device consists of a constraining cylinder mechanism, a lifting hydraulic system and a positioning hydraulic system. Horizontal forward constraint is applied to the wheel tested by the constraining cylinder to test that the wheel is in a stable state. The lifting and positioning hydraulic systems are connected through a connecting arm in a herringbone shape, so that the constraining cylinder can move freely in a two-dimensional plane.
Description
technical field [0001] The invention relates to an auxiliary detection device of automobile detection equipment in the field of automobile industry, more specifically, it relates to a wheel restraint device for detection of braking force of an automobile bench. Background technique [0002] The number of cars in use in my country is growing rapidly. With the increase in the number and speed of cars, the driving safety of cars is very important. Therefore, testing the braking performance of automobiles has become a key item stipulated by regulations. So far, most of the automobile testing stations in my country have tested the braking force of in-use vehicles on the roller brake test bench or flat brake bench. The braking force is convenient, stable, safe, fast, and repeatable, and has been widely used. There are three states when the vehicle is tested for braking force on the test bench, namely stable state, unsteady state and critical state. In the steady state, the adhes...
