Modularized rubber crawler wheel

Abstract

The invention discloses a modularized rubber crawler wheel, and relates to a crawler walking device. The modularized rubber crawler wheel comprises a frame, a modularized drive wheel, a guide wheel train, a modularized load bearing wheel train, an independent swing arm suspension and a rubber crawler. A plurality of load bearing wheel sets, a multi-dimensional balance suspension and a linear-moving type following tension structure or a fixed type tension structure are adopted, a bend steering function and a power-assisted steering function are achieved, all components and the integrated wheel are modularized, quick wheel and crawler exchanging of high-speed and heavy-duty cross-country engineering vehicles can be achieved, ground pressure of the vehicles is substantially reduced, adhesive force is improved, smoothness, stability and passing ability of the vehicles on rough topography are improved, stable traction is maintained, working reliability is improved, and using and maintaining are convenient. Meanwhile, different structures of the modularized rubber crawler wheel can be selected according to vehicle loads.

Description

technical field [0001] The invention relates to a crawler walking device, which belongs to the technical field of crawler vehicles, in particular to a modular rubber track wheel with interchangeable wheels and tracks. Background technique [0002] At present, there are mainly two types of construction vehicles: wheeled and tracked. For different terrains, different models need to be used for operations. Wheeled vehicles are suitable for ordinary ground with flat terrain and hard surface. Tracked vehicles are suitable for soft ground and harsh terrain. The track wheel is a special walking device with the characteristics of both tires and tracks. It is mainly used to solve the problem of poor passability of vehicles in complex and harsh terrains such as tidal flats, swamps, deserts, fields, ice and snow, and gravel. Compared with the integral track , track wheels have better terrain adaptability and smaller turning radius; compared with ordinary tires, track wheels have the...

AI Technical Summary

Problems solved by technology

[0009] One is the lack of steering power. Due to the large ground contact area, a larger steering force is required compared to the tires, which makes it difficult to turn the vehicle and is prone to belt stripping;

[0010] The second is that the number of road wheels is relatively small, and two sets of four-row road wheels are basically used. The total number of road wheels does not exceed 8, the ground pressure distribution is uneven, the average maximum ground pressure is high, and the passability is relatively low when supporting heavy vehicles (above 8t). Poor; at the same time, the modular road wheel train balance suspension has less dimensions and poor ride comfort;

[0011] The third is that when the modular road wheel system uses three road wheel sets, the middle road wheel set does not use the swing arm suspension. When driving on uneven terrain, the modular road wheel system is not strong enough to adapt to terrain changes and has poor ride
