Straddle type monorail vehicle framework and bogie thereof

Abstract

The invention discloses a straddle type monorail vehicle framework. The straddle type monorail vehicle framework comprises a pair of side beams and a crossbeam, wherein each of the side beam is in a Tshape, and the crossbeam is connected with the upper ends of the vertical portions of the two side beams at the same time; the longitudinal end face of a connecting region of each side beam and the crossbeam is provided with a drive device installation seat, and the two drive device installation seats are symmetric about the vertical central axis of the crossbeam; and a traction motor installation boss is installed on the outer side of each drive device installation seat, an axle installation boss is installed on the inner side of each drive device installation seat, each traction motor installation boss is provided with a shaft hole, and each shaft hole is parallel to the crossbeam and penetrates through the corresponding axle installation boss. The invention further provides a bogie ofthe framework. By the adoption of the framework, the transmission efficiency is improved, meanwhile, drive devices and axles tightly abut against each other, a whole drive system is assembled more compactly, the structure of the framework is simpler, the number of parts is reduced, cost is reduced, and vehicle operation stability and the comfort level are improved.

Description

technical field [0001] The invention belongs to the field of rail transportation, and particularly relates to a straddle type monorail vehicle frame and its bogie. Background technique [0002] There are two main types of straddle-type monorail bogies at present. One is a double-axle bogie with two axles per bogie and two running wheels on each axle; the other is that each bogie is equipped with two axles. A single axle bogie with two running wheels on each axle. Regardless of whether it is a double-axle or a single-axle, the straddle bogie needs to be equipped with guide wheels and stabilizing wheels. Generally, there are four guide wheels, two on each side of the track beam, which clamp the upper half of the track beam. There are two or four stabilizing wheels that clamp the lower half of the track beam. The guide wheel, the stabilizing wheel and the running wheel hug the track beam from three directions together to keep the vehicle running stably. [0003] In the prio...

AI Technical Summary

Problems solved by technology

[0007] 1. For the double-axle monorail bogie, the traction motor is generally arranged at an angle of 90° to the drive shaft, and bevel gear transmission is required, which affects the transmission efficiency

[0008] 2. Poor anti-rolling ability affects the stability and comfort of vehicle operation

[0009] 3. The structure of the bogie is complex and the layout is unreasonable, and the space is not optimized enough
