Brake test stand

摘要

A brake test stand for testing vehicle brakes and for determining the brake forces acting on the respective vehicle wheel. The brake test stand comprises first and second pairs of rollers for positioning the two wheels mounted on a common axis of a vehicle thereon, wherein the rollers of each pair of rollers are arranged opposite to each other and the pairs of rollers are provided side by side. A control unit controls the test stand. First sensing devices are positioned respectively below and between the rollers of each pair of rollers for sensing the pattern of the running surface of each of the tires of the wheels mounted on the common axis. A processing and calculation unit processes the data obtained by the first sensing devices for calculating tire conditions based on a correlation of the data of the coaxially mounted tires.

1. A brake test stand for testing vehicle brakes and for determining the brake forces acting on the respective vehicle wheel, the brake test stand comprises:
at least a first and a second pair of rollers for positioning two wheels mounted on a common axis of a vehicle thereon, wherein the rollers of each pair of rollers are arranged opposite to each other and the pairs of rollers are provided side by side, and wherein at least one of the rollers is driven for determining the brake forces of the vehicle wheels, a control unit for controlling the test stand, and first sensing devices positioned respectively below and between the rollers of each pair of rollers for sensing at least the pattern of the running surface of each of the tires of the wheels mounted on the common axis, characterized by a processing and calculation unit being adapted to process data obtained by the first sensing devices for calculating tire conditions on the basis of a correlation of the data of the tires of the wheels mounted on the common axis, wherein the correlation includes a correlation of the variation in the brake force and changes or variations in the tread pattern of one wheel to variations in the brake force and changes or variations in the tread pattern of the other wheel.
