Problems solved by technology

[0003] When the rail vehicle enters the slope section and the gear and the rack initially mesh, due to the uncertainty of the relative position, the gear will collide with the rack, damage the gear or the rack, and may even fail to mesh the tooth top to the tooth top

Embodiment Construction

[0026] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the use of directional words such as "up and down" generally refers to the "up and down" direction of the track beam 20 in the use state, and "left and right" refers to is the left and right of the width direction of the track beam body 21, for details, please refer to figure 1 the orientation of the drawing shown. "Length direction" includes two opposite directions. For details, please refer to image 3 the drawing orientation shown in . "Inside and outside" refers to the inside and outside of the contour of the relevant component. In addition, the terms "first", "second" and the like used in the embodime...

Abstract

The present disclosure relates to a rail beam and a rail transit system. The track beam includes a track beam body and a rack, the rack is at least partially arranged on the slope section of the track beam body, and the rack is movably arranged on the track beam body along the length direction of the track beam body for connecting with the bogie gears on. Since the rack is movably arranged on the body of the rail beam, when the gear and the rack are initially engaged, when the gear is engaged with the rack, due to the interaction force between the gear and the rack, the rack can be urged to perform the corresponding position Shift adjustment, so as to ensure that the gear can smoothly and adaptively mesh with the rack. As long as one tooth on the gear is properly meshed with the rack, the remaining teeth on the gear can be properly meshed with the rack. Therefore, the impact that may be generated during initial meshing can be buffered through the self-adaptive adjustment of the rack, and the correct meshing of the gear and the rack can be ensured, thereby ensuring that the climbing ability of the vehicle can be effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of rail transit, and in particular, to a rail beam and a rail transit system. Background technique [0002] A cog railway is a mountaineering railway. The gradient of the slope that the general railway can climb is about 4% to 6%, and the short 9% section can also be crossed during the period. In the rack railway, on the sleeper in the middle of the ordinary rail, a rack dedicated for rail vehicles is placed in addition. A rolling stock on a rack railway, equipped with one or more gears, which travel in meshing engagement with the rack. In this way, the rail vehicle can overcome the problem of insufficient adhesion, allowing the rail vehicle to climb steep slopes with a gradient of up to 48%. [0003] When the rail vehicle enters the slope section and the gear and the rack are initially engaged, due to the uncertainty of the relative position, the gear will collide with the rack, damage the gear ...
