Linear motor-driven straddle type monorail vehicle

Abstract

The invention relates to a straddle type monorail vehicle, specifically to a linear motor-driven straddle type monorail vehicle. The linear motor-driven straddle type monorail vehicle comprises at least one vehicle body and two bogies, wherein the bogies are positioned under each vehicle body; each bogie also comprises a bogie main framework, a running wheel axle, a guide wheel bracket, a stabilizing wheel bracket, a suspension device and a central traction device, wherein the running wheel axle, the guide wheel bracket, the stabilizing wheel bracket, the suspension device and the central traction device are arranged on the bogie main framework; the bogie main frameworks are connected with a linear motor mounting frame; a linear motor stator is arranged on the linear motor mounting frame;and an electromagnetic push force generated by the linear motor stator and a linear motor rotor arranged on a track beam running surface after the linear motor stator is electrified drives the vehicleto run. According to the linear motor-driven straddle type monorail vehicle, the driving performance and the braking performance of the straddle type monorail vehicle on the ice and snow or slipperytrack beam running surface are effectively guaranteed, the deadweight and later maintenance cost of the straddle type monorail vehicle are reduced, the service life of a running tire is prolonged, theuniversality is enhanced, and the operation safety is enhanced.

Description

technical field [0001] The invention relates to a straddle-type monorail vehicle, in particular to a straddle-type monorail vehicle that can effectively ensure the driveability and braking performance of the straddle-type monorail vehicle on the running surface of ice and snow or wet slippery track beams, reduce its own weight and later maintenance costs, and prolong the service life of running tires , a straddle-type monorail vehicle driven by a linear motor with versatility and improved operational safety. Background technique [0002] The structure of the current straddle type monorail vehicle is shown in the appendix Figure 10 , which adopts a rotary motor to drive the traveling wheels (2) to tow the vehicle, and a single bogie (B) has traveling wheels (2), guide wheels (3) and stabilizing wheels (4). [0003] The problems existing in the operation of straddle-type monorail vehicles with existing structures are: because the straddle-type monorail vehicles are driven by ...

AI Technical Summary

Problems solved by technology

[0003] The problem existing in the running process of the straddle monorail vehicle with the existing structure is: the straddle monorail vehicle is driven by rubber tires, and the running wheel attachment conditions on the ice and snow or wet slippery track beam running surface become worse, resulting in vehicle start-up and brake slip

Since the rotary motor drives the traveling wheel (2), a gearbox is required, resulting in heavy weight, complex transmission system, and high maintenance costs in the later period

The running tire not only has the function of supporting the vehicle, but also drives and brakes the vehicle, so the running tire wears a lot, the operation and maintenance cost is high, and the operation safety is deteriorated
