Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0020] figure 1 In the illustrated embodiment, it is a structural diagram of the existing straddle-type two-axle power bogie transmission in the background art. In order to better understand the transmission device of the present invention, the structure principle of the existing transmission device is explained: the motor 10 passes The flexible coupling transmits torque to the reducer 30; the reducer is composed of an input shaft, an intermediate shaft and an output shaft. The input shaft and the intermediate shaft are driven by a spiral bevel gear, and the intermediate shaft and the output shaft are driven by a spiral. Cylindrical gear transmission; the reducer is fixed on the frame; the axle is a hollow axle, and the drive shaft passes through the hollow axle and is connected to the running wheels, so that a reducer 30 and a brake disc 20 are arranged at ...

Abstract

The invention discloses a single axle bogie transmission of a straddle-type single rail vehicle. The transmission is arranged on a bogie frame and used for realizing that walking wheels are driven to walk through the torque of a motor. The transmission comprises the motor, a brake disc, a walking wheel assembly and a reducer. The motor and the brake disc are transversely arranged on the fixed end of an axle, and the walking wheel assembly and the wheel reducer are transversely arranged on the cantilever end of the axle; a walking wheel support shaft is unidirectionally fixed by adopting double fulcrums, one end of the support shaft is fixed on the bogie frame, the other end of the support shaft is suspended, the fixed end of the support shaft is supported by a self-aligning roller bearing, and the cantilever end of the support shaft is supported by a group of tapered roller bearings installed in an axle box in the reverse direction. Longitudinal symmetric planes of the walking wheels are coincided with longitudinal symmetric planes of track beams. The single axle bogie transmission of the straddle-type single rail vehicle has the technical beneficial effects that the bogie is compact in structure, tires are disassembled and assembled easily, and the curve passing performance of the cantilever beam straddle-type single rail vehicle is met.

Description

Technical field [0001] The invention belongs to the technical field of a straddle-type monorail vehicle bogie, and particularly relates to a transmission device for a cantilever beam-type straddle-type monorail vehicle bogie. Background technique [0002] At present, it is known that the biaxial power bogie of a straddle monorail vehicle adopts a cantilever beam structure. A bogie includes two sets of identical transmission devices, each of which is arranged in an "L" shape on both sides of the bogie. The outer end of the supporting axle of the running wheel is arranged on the axle mounting seat of the frame, and the inner end of the axle is suspended and located inside the frame. The motor, the reducer and the brake disc are longitudinally arranged at the fixed end of the axle, and the running wheel assembly is sleeved on the cantilever end of the axle transversely. When working, the torque of the electric motor or brake disc is transmitted to the running wheels through a two-...
