Problems solved by technology

[0002] In related technologies, in order to ensure the smooth operation of rail vehicles, rail vehicles are generally equipped with guide wheels and stabilizing wheels, and the guide wheels and stabilizing wheels are attached to the rail beams. However, as the rail vehicles run, the guide wheels and stabilizing wheels are always worn. Until there is a gap between the guide wheel and the stabilizer wheel and the track beam, the function of the guide wheel and the stabilizer wheel will decrease, or even fail, resulting in poor running stability of the rail vehicle

Embodiment Construction

[0044] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0045] The bogie assembly 1000 according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The bogie assembly 1000 can be applied on a rail vehicle, and the rail vehicle also includes a car body 2000 installed on the bogie assembly 1000. Above, the rail vehicle can straddle the track beam 3000 of the monorail through the bogie assembly 1000, and the rail vehicle and the track beam 3000 can constitute a part of the rail transit system.

[0046] Such as Figure 1-Figure 3 As shown, the bogie assembly 1000 may include: a bogie frame 100, a suspension system 400, a running wheel 200, an electric...

Abstract

The invention discloses a bogie assembly and a rail vehicle. The bogie assembly comprises a bogie frame, a horizontal wheel and an adjusting shim, wherein a horizontal wheel installation base is arranged on the bogie frame; the horizontal wheel can be detachably installed on the horizontal wheel installation base; the adjusting shim is inserted between the horizontal wheel and the horizontal wheel installation base. Through a way of disassembling and adding the adjusting shim, the distance from the center of the horizontal wheel to a rail beam can be reduced or increased, so that a clamping force between the horizontal wheel and the rail beam can be ensured within a design range, the processing error and the stress deformation of the bogie frame can be well made up, and the horizontal wheel installation base and the adjusting shim can well make up the problem of a smaller clamping force between the horizontal wheel and the rail beam caused by the abrasion of the horizontal wheel.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bogie assembly and a rail vehicle with the bogie assembly. Background technique [0002] In related technologies, in order to ensure the smooth operation of rail vehicles, rail vehicles are generally equipped with guide wheels and stabilizing wheels, and the guide wheels and stabilizing wheels are attached to the rail beams. However, as the rail vehicles run, the guide wheels and stabilizing wheels are always worn. Until there is a gap between the guide wheel, the stabilizing wheel and the track beam, the effect of the guide wheel and the stabilizing wheel will decrease, or even fail, resulting in poor running stability of the rail vehicle. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a bogie assembly, which can adjust...
