摘要

the unit has a belt (1) running over two circulation rollers (2,3), simulating the road surface, consisting of a reinforced rubber-elastic material and internally structured as a multiple rib V-belt, a vertically movable frame (7) in which the circulation rollers are mounted and a supporting unit for a region of a test section of the belt on which the vehicle wheel (5) is placed. The rollers are mounted close together in the frame. A single supporting roller (6) with a V-belt profile forming the supporting unit is mounted in the frame to be movable translationally and in controlled manner by a drive arrangement (11)
