Problems solved by technology

The above road-rail vehicles are mainly used for manual traction operations, have certain mobility, and the railway speed is low (20-30km / h), not suitable for rapid rescue and unmanned road-rail vehicles.
When switching between highways and railways, it mainly relies on manual work. If accurate positioning cannot be achieved, alignment needs to be repeated many times. The alignment time is long and the efficiency is low.
Moreover, the above-mentioned public-rail dual-purpose vehicles are mainly switched at level crossings, and the line environment at other positions on the track cannot be switched smoothly.
In addition, the driving method is manual driving. However, when driving manually, the environmental speed limit conditions such as different curves cannot be accurately controlled, it is easy to overturn, and the reliability is very low. There is a strict speed limit when driving on the railway. Generally, the speed limit is within 45km / h, and it is mostly within 30km / h for daily use.
In addition, road-rail dual-purpose vehicles are heavy, and cannot carry heavy equipment under road-wheel driving conditions

Embodiment 1

[0034] Figure 1 to Figure 3 A preferred embodiment of a road-rail vehicle according to the invention is shown. As shown in the figure, the road-rail vehicle includes a vehicle body 1 and a lifting and rotating mechanism 4 located at the bottom of the vehicle body 1 and connected to the vehicle body 1. The road-rail vehicle also includes a track wheel drive system 3 and a road wheel drive system 2 that are respectively connected to the vehicle body 1, wherein the track wheel drive system 3 is used for running on the track 6, and the road wheel drive system 2 is used for running on the track 6. Driving on roads, wet dirt roads, etc.

[0035]When in use, first the road-rail vehicle is driven perpendicular to the longitudinal direction of the track 6 onto the track 6 through the road wheel drive system 2, and then the lifting and rotating mechanism 4 is extended downwards and the road-rail vehicle is lifted to a certain extent. height, so that the lowest point of the road-rail ...

Embodiment 2

[0077] This embodiment is basically the same as Embodiment 1. For the sake of brevity, in the description process of this embodiment, the same technical features as Embodiment 1 will not be described, and only the differences between this embodiment and Embodiment 1 will be described:

[0078] Such as Figure 13 As shown, in this embodiment, the track wheel drive system 3 is rotationally connected with the vehicle body 1 through the rotating mechanism 8, and the road wheel drive system 2 remains stationary relative to the vehicle body 1, so that the bottom of the road wheel drive system 2 is higher than Or lower than the bottom of the track wheel drive system 3, thereby realizing the switching between the road wheel drive system 2 and the track wheel drive system 3.

[0079] Specifically, the track wheel drive system 3 includes a front track wheel drive unit and a rear track wheel drive unit at the front end of the vehicle body 1, respectively, and the front track wheel drive ...

Abstract

The invention relates to the technical field of railway equipment, in particular to a vehicle dually used for highways and railways. The vehicle comprises a vehicle body, a track wheel driving systemand a highway wheel driving system. The track wheel driving system and the highway wheel driving system are connected with the vehicle body. The bottom of the vehicle body is equipped with an elevating rotary mechanism. The highway wheel driving system can elevate relative to the track wheel driving system such that the bottom of the highway wheel driving system is higher or lower than the bottomof the track wheel driving system. Therefore, switch between the highway wheel driving system and the track wheel driving system is achieved. The vehicle used for highways and railways automatically and freely switches between the track wheel driving system and the highway wheel driving system such that the vehicle used for highways and railways can rapidly switch between highways and railways under multiple roadbed conditions. Accordingly, the vehicle can rapidly go up and down a track under intelligent control.

Description

technical field [0001] The invention relates to the technical field of railway equipment, in particular to a road-rail dual-purpose vehicle. Background technique [0002] The dual-purpose technology of highway and railway at home and abroad is mainly used for railway traction, which can realize fast switching between different railway lines. Foreign countries are represented by the Unimog road-rail vehicles of the American Tramobi Company and German Mercedes-Benz, and the domestic road-rail vehicles of Harbin Railway Bureau Internal Combustion Machinery Factory and Dalian Tiefeng United Technology Co., Ltd. to represent. The above road-rail vehicles are mainly used for manual traction operations, have certain mobility, and the railway speed is low (20-30km / h), which is not suitable for rapid rescue and unmanned road-rail vehicles. When switching between highways and railways, it mainly relies on manual work. If accurate positioning is not possible, alignment needs to be re...
