Problems solved by technology

[0003] On the dry railway track surface, the friction coefficient between the road and railway dual-purpose wheels and the rails is relatively large, but in rainy and snowy weather, the friction coefficient between the road and railway dual-purpose wheels and the rails will decrease sharply, so the existing road and railway dual-purpose wheels Wheels cannot be used in rainy or snowy weather conditions

Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] Such as figure 1 As shown, a road and rail dual-purpose wheel with anti-skid function includes a wheel hub 1, a tire 2 and a telescopic mechanism, the tire 2 is sleeved on the outer periphery of the wheel hub 1, and the tire 2 is interference fit with the wheel hub 1. The tire 2 is provided with at least two anti-skid mechanisms, and the anti-skid mechanisms are evenly distributed in the tire 2 in the circumferential direction;

[0029] The telescoping mechanism includes a driving unit and at least two moving units, the driving unit is arranged in the hub 1, the driving unit is connected to the moving unit, and each moving unit is evenly distributed ar...

Abstract

The invention relates to a highway and railway dual-purpose wheel with an anti-skid function. The wheel comprises a hub, a tire and a telescopic mechanism. At least two anti-skid mechanisms are arranged in the tire. The telescopic mechanism comprises a drive unit and at least two movement units. The drive unit comprises a first motor, a lead screw and a nut. Each movement unit comprises a connecting rod, a movable rod, a limiting board, a limiting groove and two limiting components. Each limiting component comprises a reset component, a first groove, an elastic block and a second groove. Eachanti-skid mechanism comprises a second motor, a sliding unit, a rotary rod, a limiting block and an anti-skid block. By the adoption of the highway and railway dual-purpose wheel with the anti-skid function, a highway and railway dual-purpose function can be achieved through the telescopic mechanism, furthermore, through the anti-skid mechanisms, the roughness of the surface of the highway and railway dual-purpose wheel becomes larger in rainy and snowy weather, the friction coefficient between the highway and railway dual-purpose wheel and a track or a road surface is increased, and thereforethe anti-skid performance of the wheel is improved.

Description

technical field [0001] The invention relates to the field of road and rail dual-purpose wheels, in particular to a road and rail dual-purpose wheel with an anti-skid function. Background technique [0002] The road-rail vehicle refers to a special tractor that can run on the road and on the track. It is mainly used for track traction and shunting operations. The wheels are wheels suitable for road and rail vehicles. [0003] On the dry railway track surface, the friction coefficient between the road and railway dual-purpose wheels and the rails is relatively large, but in rainy and snowy weather, the friction coefficient between the road and railway dual-purpose wheels and the rails will decrease sharply, so the existing road and railway dual-purpose wheels The wheels cannot be used in rainy or snowy weather conditions. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a road and rail dual-purpose wheel with anti...
