Test bench setup for determining tire and / or brake wear

Abstract

To reduce the distortion of measurements due to particle loss and / or particle input and to improve the accuracy of particle measurement results, a test bench arrangement (1), in particular for determining tire and / or brake abrasion of a tire (6) to be tested, is proposed in which an interior space (3) enclosed by a housing (2) is at least partially bounded on the side of a test bench roller (5) rotatable about a roller axis of rotation (9) by a cover plate (40) which at least partially covers a roller recess (4) and has a longitudinal axis (40a) normal to a tire axis of rotation (7) and / or normal to the roller axis of rotation (9).The cover plate (40) has a tire mounting area (41) extending along the longitudinal axis (40a) with a recess (42) and adjoining the tire mounting area (41), extending in the direction of the longitudinal axis (40a) of the cover plate (40) and opposite each other with respect to the tire mounting area (41). The tire mounting area (41) is recessed relative to the side areas (43, 44), and the recess (42) exposes at least that area of ​​the roller tread (5a) on which the tire (6) to be tested rolls during a test run.
