Towing vehicle capable of being used for both roads and rails

Abstract

The invention discloses a towing vehicle capable of being used for both roads and rails. The towing vehicle capable of being used for both roads and rails can make full use of the weight of the entire vehicle, is good in driving stability, is high in speed, and has low requirements for sites. The towing vehicle capable of being used for both roads and rails comprises a vehicle frame, a front axle, a rear axle, a front towing mechanism, a rear towing mechanism, a front guide mechanism and a rear guide mechanism, wherein a front wheel is arranged on the front axle, a rear wheel is arranged on the rear axle, the vehicle frame is a hinged type vehicle frame, the hinged type vehicle frame comprises a front vehicle frame and a rear vehicle frame, the front vehicle frame is connected with the rear vehicle frame through a pin shaft, vehicle frame driving hydraulic cylinders are respectively arranged at two sides of the vehicle frames, two ends of each vehicle frame driving hydraulic cylinder are hinged to the front vehicle frame and the rear vehicle frame respectively, a revolution rail-getting-on device is arranged at the front end of the rear vehicle frame, the front wheel and the rear wheel are both of a double-tire structure, and the center distance of each inside tire is the same as the rail gauge. The towing vehicle capable of being used for both roads and rails adopts the hinged type vehicle frame, permits both the front axle and the rear axle to be provided with double tires, guarantees that the inside tire of the front axle and the inside tire of the rear axle are contacted with a rail when the towing vehicle drives on the rail, and achieves full-wheel driving.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a road-rail dual-purpose tractor. Background technique [0002] The road-rail dual-purpose tractor is a special equipment that can not only pull and shunt cars on the track, but also drive on the road. With the development of rail transit, public-rail vehicles have been widely used. [0003] At present, the existing road-rail dual-purpose tractors, a class is based on the refitting of truck chassis, and a class is a special-purpose railway-road dual-purpose tractor. The road-rail dual-purpose tractor modified with the truck chassis is easy to derail due to the lack of corresponding rail running guides, poor power performance, and small adhesion of the turbine. At the same time, due to the difference between the wheel base and the track gauge of the tractor, the weight of the whole vehicle is not fully utilized, which reduces the traction capacity and causes waste of energy.

AI Technical Summary

Problems solved by technology

The road-rail dual-purpose tractor refitted from the truck chassis is easy to derail due to the lack of corresponding rail running guides, poor power performance, and small adhesion of the turbine

At the same time, due to the difference between the wheel base and the track gauge of the tractor, the weight of the whole vehicle is not fully utilized, which reduces the traction capacity and causes waste of energy

Due to the small wheelbase of the road-rail dual-purpose tractor dedicated to the site, the driving stability of the vehicle on the road is not enough. The driving speed is not fast, and the weight is light and the traction is small. It is mainly suitable for shunting operations in small freight yards, factories and mines, special warehouses, railway vehicle factories, railway depots, subway light rail depots and other places.
