Problems solved by technology

[0003] The application of rack cars in some coal mines and other mining fields is also relatively simple, and it cannot meet the conditions for passenger-carrying operations
At present, the rack drive device is generally a mixed drive type of wheel-rail and rack. Its main defects are as follows: two-axis drive is used, two sets of wheels are respectively equipped with corresponding drive devices, and there are many equipment installed on the bogie. Complex, and the structure of the driving device is complicated, and it needs to be equipped with a special clutch switching device. Its size and weight are very large, resulting in an overweight bogie and a large load on the line. The costs of the vehicle and the line are very high

Embodiment Construction

[0040] like Figure 1-7 As shown, a rack car bogie includes a frame 1 and two sets of wheelsets mounted on the frame 1 , one of which is a driving wheel set and the other is a non-driving wheel set 14 .

[0041] The drive wheel pair includes a drive shaft 2 and a wheel 4 connected to the drive shaft 2 through a bearing 3 , and the wheel 4 moves independently relative to the drive shaft 2 .

[0042] The frame 1 includes two parallel longitudinal beams 11, an end beam 12 arranged at both ends of the longitudinal beams 11 and connecting the two longitudinal beams 11, an intermediate beam 13 arranged in the middle region of the longitudinal beams 11, the intermediate beam 13 and the non- The distance between the axles of the drive wheel pair 14 is smaller than the distance between the intermediate cross member 13 and the drive shaft 2 .

[0043] A rack wheel 5 is installed at the center of the drive shaft 2 with an interference fit. The rack wheel 5 includes a ring gear 51, a ge...

Abstract

The invention discloses a toothed rail car bogie. The toothed rail car bogie comprises a framework and two groups of wheel pairs, wherein the two groups of wheel pairs are mounted on the framework; one group of the two groups of wheel pairs is driving wheel pairs; the other group is non-driven wheel pairs; the driving wheel pairs comprise driving shafts and wheels, wherein the wheels are connectedwith the driving shafts through bearings; the wheels independently move relative to the driving shafts; toothed rail wheels are mounted on the driving shafts in the form of interference fit; and a driving device used for driving the driving shaft to rotate is connected to the framework. The toothed rail car bogie has the advantages that the deadweight of the vehicle can be effectively reduced, the structure of the bogie can be simplified, the performance of the bogie can be improved, the curve trafficability of the vehicle can be improved and so on.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a rack car bogie. Background technique [0002] The cog railway is to add a steel rail with "cogs" in the middle of the ordinary railway. The rack wheel of the bogie equipped on the rack car meshes with the rack on the track, so as to realize the traction and braking of the rolling stock, and its maximum climbing gradient can reach 250‰. [0003] The application of rack cars in some mining fields such as coal mines is also relatively simple, and cannot meet the conditions for passenger-carrying operations. At present, the rack drive device is generally a mixed drive type of wheel-rail and rack. Its main defects are as follows: two-axis drive is used, two sets of wheels are respectively equipped with corresponding drive devices, and there are many equipment installed on the bogie. It is complex, and the structure of the driving device is complicated, and it needs t...
