Single-axle bogie with tumbler journal boxes for straddle type single rail vehicle

Abstract

The invention relates to a single-axle bogie with tumbler journal boxes for a straddle type single rail vehicle. The single-axle bogie with the tumbler journal boxes for the straddle type single rail vehicle comprises a frame, a pair of running wheels, two pairs of guide wheels and a pair of stabilizing wheels; the frame is a square-shaped frame and comprises two side beams and two cross beams; an axle is connected with a transmission component and a brake disc; the running wheels are mounted on the axle and rotate together with the axle; a pair of tumbler journal boxes are arranged on the axle on the external sides of the running wheels; one ends of the tumbler journal boxes are connected with one cross beam of the frame through rotation joints; and air springs are arranged between the other ends of the tumbler journal boxes and the other cross beam of the frame. Compared with the prior art, the single-axle bogie with the tumbler journal boxes for the straddle type single rail vehicle has the advantages that the vertical stability is good because vertical buffering is achieved by using the tumbler journal boxes and the air springs; the transverse stability is good because transverse buffering is achieved by using lifting rods; curve passing ability is good because the single-axle bogie adapts to the displacements of a vehicle body and the bogie on a curve by using the lifting rods; and the bogie design is simplified, the mass of the bogie is reduced and the structure of the bogie is compact.

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 using a pivoting arm type axle box. 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 ...

Problems solved by technology

[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
