Abstract

The invention provides a travelling system used for a road-rail vehicle. A rail vehicle is connected with a road travelling system at the same time. A vehicle body translation mechanism and a vehicle body lifting mechanism are connected with the mass cg of a vehicle body. A rear road wheelset mainshaft and a rear rail wheelset mainshaft depend on a V-shaped belt pulley and commonly use a power system with the V-shaped belt pulley; two H-shaped guideways of a vehicle body translation mechanism are respectively vertical to the vehicle body; the corresponding position of the vehicle body is connected with a fixed bracket and the lower end thereof is connected with a supporting shaft and a rolling bearing which is coincident with the internal wall of the upper beam of the guideway; a fixed shaft is connected between adjacent fixed brackets; the rolling wheel on the fixed shaft is coincident with the upper beam surface of the guideway; the right internal wall of the bottom beam of the guideway is connected with a rack; a transmission shaft between the two guideways is connected with the V-shaped belt pulley and an axle box; gears at the two ends of the transmission shaft are respectively engaged with the rack; the axle box is fixedly connected with a vehicle chassis; the vehicle body can implement the translation from the station to the rail along the guideway; the lifting mechanism of the vehicle body can lead the railway wheelset to fall on the rail, thus implement the mutual road-rail conversion of the road-rail vehicle.

Description

technical field [0001] The invention relates to a dual-purpose vehicle that can be used for rail transit and land, in particular to a running and conversion system of a land-rail dual-purpose power supply line maintenance vehicle, and belongs to the technical field of urban rail transit. Background technique [0002] The completion of the urban rail transit system has greatly facilitated people's travel and alleviated the disadvantages of urban traffic to a large extent. It has the advantages of large transportation volume, fast speed, punctuality, low energy consumption, comfortable and convenient ride, etc. Electric energy is a necessary energy source for the rail transit system. Almost all rail transit equipment is inseparable from the power supply. Once the power supply is interrupted, the entire rail transit system will be paralyzed. Therefore there is an urgent need for some subway and light rail power supply line maintenance vehicles to ensure that urban rail transit...
