Straddle type single-track operating vehicle with four-wheel-pair structure

Abstract

The invention relates to an urban railway operating vehicle and particularly relates to a straddle type single-track operating vehicle with a four-wheel-pair structure. The problems of heavy carriage, complex driving mode, low driving efficiency, heavy bogie, and the like, of the present operating vehicle are solved. The straddle type single-track operating vehicle comprises a carriage, a front bogie, a rear bogie, an I position wheel pair, an II position wheel pair, an III position wheel pair and an IV position wheel pair, wherein each bogie comprises a frame, a vehicle body supporting device and a dragging device; the whole frame has an II-shaped all-steel welded plate type box structure and comprises a lateral beam, an end beam, a central beam and a longitudinal beam; a motor bracket is fixed between the upper part of the lateral beam and the longitudinal beam; the I position wheel pair and the II position wheel pair are mounted on the motor bracket of the rear bogie; the III position wheel pair and the IV position wheel pair are mounted on the motor bracket of the front bogie; a guide wheel assembly is mounted in the middle of the lateral beam; a stable wheel assembly is mounted on the lower part of the lateral beam. The line demand on a single rail PC beam is reasonably met; the safety factor is high; the traction performance is excellent; the structure is simple; the repairing is easy; the vehicle running is stable; the braking performance is excellent.

Description

technical field [0001] The invention relates to an urban track operation vehicle, in particular to a straddle type monorail operation vehicle with a structure of four pairs of wheels. Background technique [0002] With the development of straddle-type monorail railway lines at home and abroad, there is a huge demand for high-quality rail operating vehicles for construction, repair and maintenance of its lines. Straddle-type monorail operating vehicles are special projects for the construction of monorail transportation systems For machinery, the vehicle chassis has a narrow space and does not require high operating speed, but requires good low-speed stability and large starting torque. The existing straddle-type monorail vehicle has a heavy compartment, small space, complex transmission mode, and relatively high energy consumption in energy conversion, resulting in low transmission efficiency and affecting the running stability of the vehicle. The existing design of the ...
