Problems solved by technology

However, when the rack vehicle passes through the gear-entry transition section, since the gear is fixedly connected to the bogie axle, during the process of meshing adjustment of the gear, the impact of the top teeth of the gear teeth and the longitudinal force during the meshing adjustment of the tooth position make the wheel tread and The rails change from rolling to longitudinal sliding. At the same time, the speed difference between the gear and the wheel will also cause the wheel tread and the surface of the rail to slip during the transition adjustment process. Scratched and heavily worn

Embodiment 1

[0040] like Figure 1-6 As shown, a low-wear rack transition auxiliary device for rack transportation according to the present invention is used to be arranged on the inner side of the steel rail 1, and the transition auxiliary device includes a support seat 2, and the support seat 2 slides or A support plate 3 is connected in a rolling connection, a limiting member is provided on the side of the support plate 3 , and the support plate 3 is used to support the rim of the wheel 4 .

[0041]Specifically, as Figure 1-2 shown, two transition aids are shown. The device should be symmetrically arranged in pairs on the inner sides of the two rails 1, such as image 3 shown (only one side is shown).

[0042] like Figure 4-5 As shown, the support base 2 includes a trough-shaped structure, and the trough-shaped structure is used for the side plate 1 near the rail 1 and the side plate 2 on the other side. The side plate 1 and the side plate 2 A number of rollers 21 are spaced apar...

Abstract

The invention discloses a low-wear rack transition auxiliary device for rack transportation, which is arranged on the inner side of the steel rail. A limit member is provided on the side of the support plate, and the support plate is used to support the rim of the wheel. The device temporarily separates the contact surface of the wheel and the rail through the temporary support of the wheel rim. At the same time, the impact of the top tooth between the traction gear and the transition rack and the longitudinal force during the adjustment of the gear tooth meshing cause the wheel and the rail to separate. The sliding friction between them can be effectively transformed into the translation of the wheel and the support plate together, which can effectively avoid the friction and wear of the wheel tread and the rail, improve the service life of the corresponding parts, and facilitate the smooth increase of the gear speed of the rack vehicle and the smooth meshing of the gear teeth. Ensure the high efficiency and stability of the rack vehicle when entering the rack section, so that the rack vehicle can transition to the rack section better without stopping.

Description

technical field [0001] The invention relates to the technical field of rack railway structures, in particular to a low-wear rack transition auxiliary device for rack transportation. Background technique [0002] Compared with the traditional rail transit railway, the most obvious feature of rack transportation is that a separate rack track will be built and laid in the middle of the laid railway track, and at the same time, the middle of the bogie of the rail vehicle running on it is provided with a corresponding rack. The gear, when the rack vehicle travels in the mountains or on the road with steeper slope, through the meshing between the gear and the rack track, it can provide the rail vehicle with greater climbing power, overcoming the gap between the wheel hub and the rail of the traditional rail vehicle. The problem of insufficient adhesion allows the rail vehicle to travel smoothly on the terrain with steeper slopes. Because the cog railway is suitable for transporta...
