Embodiment

[0019] Such as figure 1 As shown, a rack drive system includes an axle 1 and wheels 2 installed at both ends of the axle 1, and also includes a rack drive gear 3, a reducer and a traction motor 6, and the rack drive gear 3 is fixed in an interference fit form Installed in the middle of the axle 1, the housing 5 of the reducer is hugged on the axle 1 through tapered roller bearings on both sides and positioned axially, the input shaft of the reducer is connected with the output shaft of the traction motor 6, and the deceleration The transmission gear 4 of the reducer is assembled as the output shaft of the reducer by its output end gear and the axle shaft 1 in the form of interference fit. The traction motor 6 is suspended on the vehicle bogie.

[0020] The transmission gear 4 of the speed reducer is in the form of a two-stage reduction gear.

[0021] There is no cog on the track with a slope not greater than 40‰, and the traction torque generated by the traction motor 6 is t...

Abstract

The invention discloses a toothed rail driving system. The toothed rail driving system comprises an axle and wheels mounted at the two ends of the axle, and further comprises a toothed rail driving gear, a reducer and a traction motor. The toothed rail driving gear is fixedly mounted in the middle of the axle in an interference fit mode; a shell of the reducer is held on the axle through bearingson the two sides of the shell and axially positioned; an input shaft of the reducer is connected with an output shaft of the traction motor; and a transmission gear of the reducer enables an output end gear of the transmission gear and the axle to be assembled in an interference fit mode to serve as an output shaft of the reducer. The toothed rail driving system has the beneficial effects that a vehicle provided with the toothed rail driving system can climb a toothed rail line with the line slope being larger than 4%, transportation is convenient and fast, intercity rail traffic transportation can also be achieved at a conventional rail line with the slope being smaller than 4%, and meanwhile the toothed rail driving system adapts to compound transportation of the conventional line and the toothed rail line, and is suitable for traffic of tourist attractions with the large passenger flow volume and high altitude.

Description

technical field [0001] The invention relates to a cog rail drive system, which is used for a cog rail vehicle 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 40‰. As the line slope further increases, wheel and rail slippage will occur in driving accidents. [0003] The rack vehicle is a rail transit train used on rack tracks, and is suitable for climbing large ramp lines with a slope greater than 40‰. The rack drive system is installed on the bogie of the rack vehicle, and has the following characteristics: the weight of the vehicle is carried by steel wheels on two ordinary rails of a certain gauge; a rack is set between the two ordinary rails, and the wheel set There is a drive gear meshing with the rack rails to provide traction and braking force for vehicles on the steep track.
