A straddle-type monorail operating vehicle with two pairs of wheels

Abstract

The invention relates to an urban rail operation vehicle and in particular relates to a straddle type monorail operation vehicle with a structure comprising two pairs of wheels. The straddle type monorail operation vehicle comprises a carriage, a steering frame, an engine, a transfer case and a walking pump, wherein the steering frame is connected with an underframe of the carriage through a central pin dragging device; the steering frame comprises a framework, a secondary suspension device and a dragging device; the overall framework is of an II-shaped full-steel installed and welded plate type box structure and comprises a side beam, end beams connected to two ends of the upper part of the side beam and two vertical beams which are connected between the end beams; a motor bracket is fixed between the upper part of the side beam and the corresponding vertical beam; two independently-driven walking wheel assemblies are mounted on two motor brackets; four guide wheel assemblies are mounted on two sides of the middle part of the side beam; two stabilizing wheel assemblies are mounted on two sides of the lower part; the secondary suspension device adopts a secondary steel coil spring assembly. The straddle type monorail operation vehicle can reasonably meet the circuit requirements of monorail PC beams and is high in safety coefficient, excellent in dragging performance, simple and compact in structure, easy to maintain, stable in running and excellent in brake performance.

Description

technical field [0001] The invention relates to an urban track operation vehicle, in particular to a straddle-type monorail operation vehicle with a two-pair wheel structure. Background technique [0002] With the development of 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 monorail operating vehicles are special engineering machinery used for construction operations of monorail transportation systems , the chassis space of the vehicle is narrow, and the requirements for running speed are not high, but it 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 bo...
