Single-axle bogie of straddled-type single-rail vehicle with rotating arm type swing bolsters

Abstract

The invention relates to a single-axle bogie of a straddled-type single-rail vehicle with rotating arm type swing bolsters. The single-axle bogie of the straddled-type single-rail vehicle with the rotating arm type swing bolsters comprises a pair of traveling wheels, two pairs of guiding wheels, a pair of stabilizing wheels and a framework for mounting the traveling wheels, the guiding wheels and the stabilizing wheels; wherein the framework is 'square'-shaped and comprises side beams and cross beams; two pairs of swing bolsters are symmetrically arranged above the cross beams of the framework in the transverse direction; the swing bolsters have rotating arm type structures; the inner ends of the swing bolsters are connected with the cross beams of the framework through rotating joints and rotate in the side rolling direction; and an air spring is arranged between the outer end of each swing bolster and the frame in the vertical direction. Compared with the prior art, the single-axle bogie of the straddled-type single-rail vehicle with the rotating arm type swing bolsters has the characteristics that vertical buffering is realized by the rotating arm type swing bolsters and the air springs, and the vertical stability is good; transverse buffering is realized by a boom, and the transverse stability is good; by the boom, deflection between a vehicle body and the bogie in the curve is adapted, and the curved passing ability is good; by the rotating arm type swing bolsters and side rolling resisting springs, side rolling resisting rigidity is provided, and the anti-roll ability of the vehicle body is improved; and the height of a floor surface of a passenger room can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of straddle-type monorail vehicles, in particular to a single-axle bogie of a straddle-type monorail vehicle adopting a swing arm type bolster. Background technique [0002] The straddle-type monorail transportation system has the advantages of strong adaptability to complex terrain, less land occupation, moderate transportation volume, and low cost. It has become one of the preferred types of rail transit in small and medium-sized cities, mountainous cities, and cities with complex geology. The straddle monorail vehicle is mainly supported, guided and stabilized by a track beam. The vehicle rides on the track beam, and the center of gravity of the vehicle is above the track. The main difference from traditional railway vehicles is that the running part of the vehicle uses rubber tires, and guide wheels and stabilizing wheels are set on both sides of the track beam. The track beam of the straddle monorail h...

[0004] The Bombardier straddle monorail vehicle adopts a single-axle bogie. The main structure of the bogie includes: 1 pair of running wheels, 4 guide wheels, 2 stabilizing wheels, a "mouth"-shaped frame, an hourglass-shaped rubber spring, and 4 space linkages for traction System, wheel hub motor and current collector shoe, the axle of the running wheel is fixed on the side beam of the frame, the stator of the permanent magnet synchronous motor is arranged on the axle, the rotor is arranged on the wheel hub, the wheel rotates but the axle does not rotate, the suspension system adopts The hourglass-type rubber spring provides both vertical and lateral buffering functions. The space 4-link traction system not only transmits the longitudinal force between the car body and the bogie, but also restrains the nodding movement between the bogie and the car body. However, the existing single The vertical stability, lateral stability and curve passability of axle bogie are not ideal
