Wheel side driving device for straddle type monorail vehicle

Abstract

The invention relates to a wheel side driving device for a straddle type monorail vehicle. The wheel side driving device comprises a gearbox and a traction motor, wherein the traction motor is fixedly arranged at the input end of the gearbox, and the output end of the gearbox is used for being fixedly connected with a frame body of a bogie. The gearbox internally comprises a sun wheel, an inner gear ring is inlaid on a shell of the gearbox, a planet gear is arranged between the sun wheel and the inner gear ring, and a planet carrier of the planet gear is fixedly connected with a driving shaft for driving walking wheels of the bogie to walk; an output shaft of the traction motor is fixedly connected with the sun wheel and is arranged in the transverse direction of the frame body. By means of the wheel side driving device, a driving device of the monorail vehicle is laid out more reasonably, the transmission efficiency is higher, and the requirements for light weight and low energy consumption of the bogie are met. In addition, by means of the layout of the driving device, it is possible to install a side-rolling-resisting torsion bar on the bogie, and a basis is provided for enhancing stability of the current bogie of the straddle type monorail vehicle.

Description

technical field [0001] The invention relates to the technical field of monorail vehicle manufacture, in particular to a wheel-side driving device of a straddle type monorail vehicle. Background technique [0002] With the acceleration of my country's new urbanization process, the urban population has grown rapidly, from small cities to large cities, from mountainous cities to plain cities, and problems such as serious environmental pollution, traffic congestion, and energy shortages have become more acute. The traditional public transportation system can no longer meet the needs of urban green and fast transportation development. The fundamental way to solve urban transportation problems lies in the development of urban rail transit. [0003] Straddle-type monorail transit is a typical urban rail transit system, which has unique advantages such as strong terrain adaptability, large climbing ability, small turning radius, less land resource occupation, low noise, short constr...

Problems solved by technology

[0007] Due to the large number of gears included, this kind of gearbox is not only heavy, but also has a large volume, which takes up a lot of space on the bogie, which is extremely unfavorable for the arrangement of other mechanisms on the bogie, which leads to the overall appearance of this kind of bogie. The problems of bulkiness and high energy consumption; at the same time, because the three-phase asynchronous motor and the gearbox are respectively located on both sides of the beam in the middle of the frame, the torque of the motor needs to go through multiple stages before it can be finally transmitted to the running wheels, and the transmission efficiency is low. Exacerbated the problem of high energy consumption of the bogie
