Embodiment

[0017] Such as figure 1 , 2 As shown, a rack bogie suitable for large-slope rail transportation includes a bogie frame body 1 on which a wheel set 2, a primary suspension 3 and a secondary suspension 4 are installed. The driving gear 5 that is also installed between the wheel pairs 2 on the bogie frame body 1 is meshed with the toothed rack between the two rails.

[0018] A wheel pair driving device 8 for driving the wheel pair 2 and a wheel pair braking device 9 for braking the wheel pair 2 are also installed on the bogie frame body 1 .

[0019] A traction device 7 is also installed on the bogie frame body 1 .

[0020] A rack drive device 6 for driving the drive gear 5 is also installed on the bogie frame body 1 . The rack driving device 6 includes a traction motor, a shaft coupling, a transmission gearbox and a hollow axle shaft. The traction torque generated by the traction motor penetrates into the transmission gearbox through the coupling joint, and then is transmitted...

Abstract

The invention discloses a gear bogie suitable for steep-slope rail transit transportation. The gear bogie suitable for the steep-slope rail transit transportation comprises a bogie body; wheel pairs,a primary suspension and a secondary suspension are mounted on the bogie body; and a driving gear engaged with a toothed rail between two steel rails is also mounted in a position, between the wheel pairs, on the bogie body. The gear bogie suitable for the steep-slope rail transit transportation has the advantageous effects that the capability of running on toothed-rail lines (toothed-rail lines with climbing slopes of 5-45 %) and traditional lines (traditional lines with slopes of not larger than 5 %) is realized because the driving gear is mounted on the bogie body for the first time; the gear bogie suitable for the steep-slope rail transit transportation is especially suitable for transportation in tourist attractions with intensive passenger flow volumes and directly switched between the toothed rail lines and the traditional lines; and therefore, the gear bogie suitable for the steep-slope rail transit transportation is convenient and fast.

Description

technical field [0001] The invention relates to a bogie, in particular to a rack bogie suitable for large-slope rail transportation, and belongs to the technical field of rail vehicles. Background technique [0002] Existing railway rail transit vehicles are only suitable for running on track lines with a slope not higher than 50‰. As the line slope increases further, driving accidents may occur due to slipping of wheels and rails. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems, to provide a rack bogie suitable for large-slope rail transportation, which is applied to rail traffic trains on rack tracks (referred to as "racks"), suitable for climbing Climb the big ramp line with a slope of 450‰. [0004] The technical scheme that the present invention adopts is like this:. [0005] A rack bogie suitable for large-slope rail transportation, including a bogie frame body on which wheelsets, primary suspension a...
