Toothed rail train having power switching function and suspension hinge structure

Abstract

The invention discloses a toothed rail train having a power switching function and a suspension hinge structure and relates to the technical field of rail traffic. The toothed rail train comprises atleast one train unit. The train unit comprises a first motor vehicle, a second motor vehicle and a third motor vehicle which are hinged to one another in sequence. A toothed rail and wheel rail integrated steering frame is arranged at each of the two ends of the bottom of the second motor vehicle, and a toothed rail and wheel rail integrated steering frame is arranged at the end, away from the second motor vehicle, of the bottom of each of the first motor vehicle and the third motor vehicle. Every two adjacent motor vehicles are subjected to end portion connection through a suspension hinge connecting device, and gravity at the end portions, close to the second motor vehicle, of the first motor vehicle and the second motor vehicle can be transmitted to the second motor vehicle. By the implementation of the technical scheme, configuration of power steering frames can be effectively reduced, power can be output to wheels or drive gears on the same wheel axle, the traction power of the train can be sufficiently exerted, and the requirement for a mixed line of the maximum 4% of a common wheel rail ramp and the maximum 25% of a toothed rail ramp can be effectively met.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rack train with a power switching function and a suspension hinge structure. Background technique [0002] The cog railway is a kind of mountain-climbing railway, in which one or more special toothed tracks are laid in the middle of the ordinary railway track, and one or more gears are equipped on the bogies of the locomotives running on the cog railway correspondingly, when the train When running on the rack line, the traction force and braking force are transmitted through the meshing of the gear and the rack railway rack, so as to overcome the problem of insufficient adhesion of ordinary rolling stock on the line with a large slope, and have a strong climbing ability. [0003] At present, cog railways are generally pure cog railways, which are mostly used for sightseeing railways in scenic spots. The maximum ramp can reach 250‰, and the line distance is generally...

Problems solved by technology

[0005] In order to solve the technical problem that the above-mentioned existing cog trains cannot meet the requirements of the 40‰ ordinary wheel-rail ramp and the 250‰ cog ramp mixed line, the purpose of the present invention is to provide a cog with power switching function and suspension hinge structure For trains, a suspension articulated connection device is used between two adjacent carriages of each train, which can effectively reduce the configuration of power bogies; because the driving force of the climbing rack train depends on the gear drive, the biggest resistance to its operation is the train on the ramp. The component force of gravity along the slope, thereby reducing the weight of the train can effectively reduce the climbing resistance of the train and thus improve the climbing ability of the rack train; The power is output to the wheels or driving gears on the wheel shaft, so that the traction power of the train can be fully exerted, which can effectively meet the mixed line requirements of a maximum 40‰ ordinary wheel-rail ramp + a maximum 250‰ rack ramp
