Wheel limit device used when testing brake performance of automobile

Abstract

The invention discloses a wheel limit device used when testing the brake performance of an automobile. The device comprises a base (1), a locating pole (2) and a catch wheel (3), wherein the lower end of the locating pole (2) is connected onto the upper end face of the base (1), and an upper annular table (4) and a lower annular table (5) are sleeved upon the upper end of the locating pole (2). The catch wheel (3) comprises a cylinder and a sealing cover plate, a round penetrating hole is formed in the sealing cover plate of the catch wheel (3), the locating pole (2) penetrates through the round penetrating hole of the sealing cover plate, and the sealing cover plate is sleeved upon the locating pole (2) between the upper annular table (4) and the lower annular table (5). A wheel can be limited and guided by the catch wheel (3) when the wheel limit device is applied to a brake test table, so that the wheel deviating from a simulated road is avoided, and the influences of artificially regulating the wheel on the test efficiency is avoided.

Description

technical field [0001] The invention relates to an auxiliary device for detecting the braking performance of an automobile, in particular to a device for limiting the position of a wheel when inspecting the braking performance of an automobile. Background technique [0002] With the popularity of automobiles, people pay more and more attention to the safety performance testing of automobiles. In the process of automobile braking performance inspection, it can be carried out in two ways: road inspection and inspection bench inspection. Among them, the inspection of the braking performance of automobiles on the road requires a large space, the wear of automobile tires is serious, and the inspection time is long and the efficiency is low, which is not convenient for popularization and application. The commonly used equipment for test bench inspection is the roller reaction brake test bench. The roller reaction brake test bench is driven by a motor as a simulated road surface. T...

AI Technical Summary

Problems solved by technology

[0003] After the roller on the existing roller reaction brake inspection platform carries the wheel, the wheel is easy to deviate from the simulated road surface formed by the roller during the rotation of the roller. At this time, the operator needs to adjust the wheel, which makes the inspection process become easier. It is cumbersome and affects the inspection efficiency
