Convertible vehicle guiding device for road and rail

Abstract

The present invention discloses a guide device of a convertible vehicle on railway and highway, pertaining to the field of transportation machinery. The device comprises a vehicle framework, a drive bridge, a driving wheel, a single-axle bogie, a guide wheel and a lifting mechanism; the single-axle bogie is connected with the guide wheel; the drive bridge and the wheel are arranged on the vehicle framework by a drive bridge suspension fork; the single-axle bogie is arranged on the vehicle framework by a guide mechanism suspension fork; the drive bridge suspension fork and the guide mechanism suspension fork both adopt a rigidity-variable mechanism such as an air spring or a hydraulic device and the rigidity-variable mechanism can automatically configure the bearing capacity of the drive bridge suspension fork and the guide mechanism suspension fork; the lifting mechanism and the single-axle bogie are connected so as to change the vehicle purpose by controlling the position of the single-axle bogie. The guide device provided by the present invention not only meets the adhesion requirement of the guide device under different loads in railway driving and prevents the vehicle from derailing under any condition and at any speed, but also satisfies the adhesion requirement for driving the vehicle drive bridge.

Description

technical field [0001] The invention relates to a dual-purpose vehicle for road and rail, in particular to a guiding device for a dual-purpose road and rail vehicle. Background technique [0002] Road and rail vehicles at home and abroad are mainly divided into two categories, one is to install a railway running system on ordinary vehicles, that is: the guide device in this paper, to realize the dual-purpose function of road and rail; The vehicle has a self-propelled hydraulically driven power bogie, and uses different driving methods to drive the vehicle on the railway and highway. The domestic vehicles are mainly the first type of vehicles, all of which are installed on the existing vehicles for various roads, and the railway running system is installed, and the original road rubber driving wheels are used to directly walk on the guide rails. [0003] Since the 1950s, Western countries have developed a lot of dual-purpose road and rail vehicles with different purposes in ...

AI Technical Summary

Problems solved by technology

Due to the limitation of the guide device, it can only be used as a railway tractor

[0005] In terms of structure, the guide devices of most road and rail vehicles are installed directly on various road vehicles. The hydraulic cylinder is connected with the frame of the vehicle, and the load shared by the guide device is basically fixed. value, when the load changes, the load on the guide device is basically unchanged, so that when the vehicle is running on the railway, its adhesion cannot change with the load change

It will cause the vehicle to run safely on the railway when it is fully loaded, but unsafe situations such as derailment may occur when it is unloaded; if it is safe when it is unloaded, it may cause insufficient adhesion on the driving rubber wheels, and the vehicle cannot walk

Therefore, most of the current road and rail vehicles are only used as special-purpose vehicles whose total mass without cargo can remain basically unchanged, and their application scope and prospects have been greatly limited.
