Front rigid-flexible conversion device for highway-railway dual-purpose vehicle and highway-railway dual-purpose vehicle

Abstract

The invention provides a front rigid-flexible conversion device for a highway-railway dual-purpose vehicle and the highway-railway dual-purpose vehicle, and relates to the technical field of vehicles.The device comprises a swing rod, a base, a pressing assembly and a driving assembly; a sliding block is arranged at one end of the swing rod, a guide sliding groove matched with the sliding block isformed in the base, and the base is connected with an automobile front axle through the pressing assembly. The driving assembly is connected with the swing rod and used for driving the swing rod to move, and the swing rod is separated from the base under the action of the driving assembly or slides into the guide sliding groove through the sliding block to be connected with the base. According tothe device, the swing rod is controlled to move to limit the base, locking of the automobile front axle is achieved, the defect that in the prior art, when an axle damping spring plays a role, an automobile body shakes is overcome, and the rail running stability of the highway-railway dual-purpose vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a road-railway vehicle, in particular to a front rigid-flexible conversion device for a road-railway vehicle and a road-railway vehicle. Background technique [0002] The road-rail vehicle is a kind of special equipment that can not only perform traction and shunting on the track, but also drive on the road. With the development of rail transit, public-rail vehicles have been widely used. [0003] As a key part of a car, the automobile axle's position and structure directly affect the driving stability of the car. When the car encounters a bumpy road, under the action of the axle damping spring, the impact received by the wheels will be greatly reduced, but at the same time it will cause the car body to shake in different degrees. When the road-rail vehicle is performing track traction operations, the shaking of the vehicle body caused by the axle damping spring will affect th...

AI Technical Summary

Problems solved by technology

[0004] The present invention overcomes the deficiencies in the prior art, and proposes a front rigid-flexible conversion device for road-rail vehicles and road-rail vehicles to solve the problem caused by axle damping springs when road-rail vehicles are performing track traction operations. The shaking of the car body affects the stability of the road-rail vehicle
