Problems solved by technology

[0005] At present, the design of the traction device of road-rail dual-purpose vehicles is unreasonable, and there is no height adjustment device. The coupler with the center pin device has too much freedom of swinging head, which leads to the risk of unbalanced load when the vehicle is propelled; There is a risk of derailment through small, small curves

Abstract

The invention discloses a traction device of a road-railer. The traction device comprises a linear guide rail module, a traction seat, a central pin, a traction rod, a transverse stop part and a vertical stop part, wherein the traction seat is fixedly connected with the linear guide rail module and has an installation space; the central pin penetrates through the installation space and is fixed to the traction seat in the axial direction; one end of the traction rod is rotationally installed on the part, located in the installation space, of the body of the central pin through a joint bearing, and the other end of the traction rod extends out of the installation space and is provided with a vehicle hook connecting plate used for connecting vehicle hooks; the transverse stop part and the vertical stop part are fixed in the installation space of the traction seat; the rod body of the traction rod can make contact with the transverse stop part and the vertical stop part. The traction device enables the road-railer to safely pass in a linear or curve or slope mode.

Description

technical field [0001] The invention relates to a road-railway vehicle, in particular to a traction device for a road-railway vehicle. Background technique [0002] With the rapid development of my country's railways and urban rail transit, the repair of various types of railway vehicles and operating lines, railway shunting operations and maintenance of in-line ancillary facilities are facing increasing pressure. The road-rail vehicle has the advantage of fast switching operation between road and railway, so it can be widely used in the repair and operation of railway vehicles and line maintenance. [0003] Road-rail dual-purpose vehicles are also called land-rail dual-purpose vehicles, which can be divided into tractors and engineering vehicles according to their uses. The tractor runs at a low speed and has a large traction force. Different coupler heads are configured according to the type of trailer to realize the shunting operation of railway vehicles and the traction...
