Roadway and railway two-purpose tractor

Abstract

The invention discloses a roadway and railway two-purpose tractor which comprises a tractor frame, seats arranged on the tractor frame and a steering wheel arranged on the tractor frame. The seats are foldable; the steering wheel is as high as the top end of the tractor frame or is lower than the top end of the tractor frame; when the roadway and railway two-purpose tractor needs to pass through a roadway or a tunnel or goods are long and the front ends of the goods extend to the upper side of the tractor and block the view of a driver or a drive position, the seats can be folded, so backrests of the seats are flush with the tractor frame, and the steering wheel is flush with the top end of the tractor frame or the steering wheel is a little higher than the top of the tractor frame. After the seats are folded, the height of the whole tractor can be effectively reduced, the steering wheel does not influence placement of the goods and the goods can be transported conveniently.

Description

technical field [0001] The invention relates to the technical field of tractors, in particular to a road-rail dual-purpose tractor. Background technique [0002] Road-rail dual-purpose tractor is an industrial vehicle that can be used to haul goods on the road and on the railway. The vehicle needs to switch its working mode when the traction conditions of the road and railway are changed. [0003] There are four groups of bridges for the road-rail dual-purpose tractor, namely, the road steering bridge, the road driving bridge, the railway supporting bridge, the railway guiding bridge, the road steering bridge and the driving bridge are equipped with road wheels, the railway supporting bridge and the railway guiding bridge. There are railway wheels installed on the bridge. [0004] During traction work on the road, the railway support bridge and the railway guide bridge are retracted, the railway wheels are separated from the ground by a certain height, and the wheels instal...

AI Technical Summary

Problems solved by technology

The steering wheel of the road-rail dual-purpose tractor with both car and remote control in the prior art is generally located directly in front of the driver, protruding from the driver's platform of the vehicle frame, and the seat cannot be folded, resulting in the overall failure of the road-rail dual-purpose tractor. The height is high. When the vehicle needs to enter the roadway or tunnel, due to the high seat or steering wheel height of the road-rail tractor, the road-rail tractor cannot pass through the roadway or tunnel, or the length of the cargo is long. The length of the cargo exceeds the front end of the trailer. Due to the influence of the seat or steering wheel of the road-rail tractor, it is impossible to carry the cargo with a long length
