Abstract

The invention discloses a split type guide wheel, a tramcar and a wheel core replacing method. The wheel core is a plastic part, the wheel core is provided with a circumferential tread and wheel rimsformed on the two sides of the circumferential tread, the circumferential tread and the two wheel rims form a groove, the circumferential tread is perpendicular to the wheel rims, and the wheel core is provided with a first shaft hole in the axis direction of the wheel core; and two end covers are detachably arranged on the two sides of the wheel core respectively, second shaft holes are formed inthe end covers, and the wheel shaft is arranged in the first shaft hole and the second shaft holes in a penetrating mode. The guide wheel can reduce the derailment risk and the operation noise, meanwhile, the wheel core is convenient to replace, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a split guide wheel, a tram and a wheel core replacement method. Background technique [0002] As a medium-capacity, environment-friendly and resource-saving public transportation tool, modern trams have been widely used in many cities and countries. The tram includes guide wheels, which are in rolling contact with the track and play a guiding role for the operation of the tram. The existing guide wheels have defects such as high running noise, high risk of derailment, high maintenance cost, and inconvenient wear monitoring. [0003] The above information disclosed in this background technology is only for enhancement of understanding of the background technology of this application, and therefore it may include information that does not constitute the prior art that is already known to a person of ordinary skill in the art. Contents of the invention [0004] In view of...
