Abstract

The invention provides a road-rail dual-purpose tractor, comprising: a main body of the tractor, the main body of the tractor includes a car body, ground wheels, rail wheels and a steering drive structure, the ground wheels are arranged at the bottom of the car body, and the rail wheels are retractable Installed at the bottom of the car body, the steering drive structure is connected with the ground wheels to drive the ground wheels to turn; when the rail wheels are on the track and the direction of the ground wheels is a preset direction, the steering drive structure has a disabled first state. The technical scheme of the invention effectively solves the problem that the road-rail tractor in the prior art is derailed due to the turning of the ground wheels when the road-rail tractor is walking on the rails.

Description

technical field [0001] The invention relates to the technical field of road-rail dual-purpose tractors, in particular to a road-rail dual-purpose tractor. Background technique [0002] Road-rail dual-purpose tractor is a special equipment that can not only drive on the road, but also pull on the railway. It is mainly used for railway traction. It is widely used in the rail transportation industry. Road-rail dual-purpose vehicles are usually used in railway stations, port terminals, industrial and mining enterprises, large and medium-sized freight yards and other workplaces with dedicated railway lines, as tractor shunting vehicles. The road-rail dual-purpose tractor is generally composed of power transmission system, steering system, braking system, hydraulic system, electrical system, frame and suspension device, road-rail guiding device, coupler and other parts. Most road-rail dual-purpose tractors use rubber tires for road drive and railway drive. When the railway is ru...
