Rail-bound gallery vehicle for underground working

摘要

Rail-bound gallery vehicle for underground mining working with supporting structure, chassis and bodies, the supporting structure having a longitudinally running central member and the chassis consisting of two twin-axle bogies with bogie cross-member, at least one of which bogies being connected by its bogie cross-member to the central member via a spherical joint. The bogie cross-members have on the two sides axle rocker arms which are supported counter to a restoring spring so as to be swivellable about a horizontal axis. The axles of the wheel are mounted in their axle rocker arms with an axle spherical joint. The axle rocker levers are positioned on their axles, designed as bearing bolts, with bearing play in the direction of the wheel axles. In this way, even in the case of considerable buckling, constraints on the axle rocker arms during their adjustment are avoided. In this way, it is ensured that when travelling over disturbed sections of rail in underground mining works all the running wheels of the chassis remain on the rails and, as it were, stick to the rails, specifically even at a high speed. <IMAGE>
