Abstract
The invention relates to a wheel centering device used for regulating a relative position between a test vehicle wheel and a track wheel (regardless of existence of centerline) on a rolling test rig of a locomotive vehicle. The wheel bases and the fixed distances of a test vehicle are different; the positions of the vehicle wheel and the track wheel are both changed; however, the centerlines of the two wheels have to be ensured to coincide within a precision allowed range to ensure that the test performance of the vehicle is not distorted. The device consists of an upper V-shaped positioning plate, a lower V-shaped positioning plate, a connecting bolt and horizontal positioning plates; in a test, the position of the track wheel (regardless of existence of a centerline mark) of the test rig is firstly regulated in place; then, the device is arranged between the test vehicle wheel and the track wheel; two horizontal positioning plates are arranged on the upper plane of a side beam of an upper axle; the lower V-shaped positioning plate is automatically centered with the centerline of the track wheel; whether the vehicle wheel is in the middle of the upper V-shaped positioning plate is judged by observing the symmetry of the position of the contact point of both sides between the vehicle wheel and the upper V-shaped positioning plate; if the vehicle wheel is in the middle of the upper V-shaped positioning plate, the vehicle wheel and the track wheel are centered; otherwise, the position of the vehicle wheel is rolled according to the position condition of the contact point of both sides between the vehicle wheel and the upper V-shaped positioning plate until centering precision is met. According to the device, the centering problem between the vehicle wheel and the track wheel caused by different wheel bases and fixed distances of various test locomotive vehicles is successfully solved.
