Abstract

The invention relates to a horizontal wheel assembly and a rail vehicle. The horizontal wheel assembly comprises a horizontal wheel (11), a guide frame (1) and a wheel axle assembly (100) for installing the horizontal wheel (11) below the guide frame (1), and the installation abutting face of the wheel axle assembly (100) and the installation abutting face of the guide frame (1) are arranged in an up-down attached mode. And the axle assembly (100) and the guide frame (1) are connected through a fastener penetrating through the two installation abutting faces. Thus, the axle assembly is installed on the guide frame from bottom to top, large-area plane contact of the upper surface of the axle assembly and the lower surface of the guide frame can guarantee that the horizontal wheel is in a horizontal state, a positioning structure does not need to be arranged, it is effectively guaranteed that the horizontal wheel is installed in the horizontal direction, an inclination angle is not generated, and eccentric wear of the horizontal wheel is prevented.

Description

technical field [0001] The present disclosure relates to the technical field of rail transportation, in particular, to a horizontal wheel assembly and a rail vehicle. Background technique [0002] In a straddle-type monorail vehicle, the running wheels are used to carry the weight of the vehicle body and are always in contact with the top surface of the track beam. The horizontal wheels are used to ensure that the monorail vehicle runs along the track and prevent the vehicle body from tipping over. The sides of the track beams are in contact. In the related art, when the horizontal wheel is installed, the direction of the installation surface of the axle assembly is perpendicular to the wheel surface of the horizontal wheel, resulting in a large installation space, which is not suitable for small rail transportation. If there is an assembly error when the bolt is fastened, it is easy to cause the tire to tilt. Contents of the invention [0003] The first object of the pre...
