All-terrain adaptive wheel track and application thereof

Abstract

The invention relates to an all-terrain adaptive wheel track and application thereof. The all-terrain adaptive wheel track comprises a planetary gear speed reduction mechanism, a movable combined typewheel hub mechanism and a rubber caterpillar transmission mechanism. The planetary gear speed reduction mechanism is connected with the movable combined type wheel hub mechanism by expansion devicesand support rods, and the expansion devices can work, so that the external shape of the movable combined type wheel hub mechanism can be changed; the rubber caterpillar transmission mechanism and themovable combined type wheel hub mechanism are connected with each other, and the rubber caterpillar transmission mechanism can be switched between a wheel type form and a caterpillar type form when the external shape of the movable combined type wheel hub mechanism is changed. The all-terrain adaptive wheel track and the application have the advantages that a brake, a clutch and hydraulic cylinders are matched with one another, and accordingly the all-terrain adaptive wheel track can be switched between wheel type and caterpillar type forms; the all-terrain adaptive wheel track can be switchedto be in the wheel type form on flat hard pavements, accordingly, the running speeds can be increased, and power consumption can be reduced; the all-terrain adaptive wheel track can be switched to bein the caterpillar type form on soft grounds, accordingly, the ground contact areas can be enlarged, tractive force can be increased, and the passing ability can be improved.

Description

technical field [0001] The invention relates to an all-terrain self-adaptive wheel shoe and its application, belonging to the technical field of vehicle running parts. Background technique [0002] At present, there are mainly three types of engineering vehicles: wheeled, tracked and convertible wheel-tracked. For different working terrains, different models need to be selected. Wheeled vehicles are suitable for flat and hard roads, tracked vehicles are suitable for soft ground with complex terrain, and convertible wheeled tracked vehicles can take into account both wheeled and tracked vehicles. However, the working environment of modern engineering vehicles is mostly not a single terrain, so convertible wheel tracked vehicles need to change wheels and tracks frequently in order to adapt to different terrains, which reduces work efficiency. [0003] Wheeled vehicles have the advantages of simple structure, high speed, simple control, stable movement, and low energy consump...

Problems solved by technology

[0007] Although the technical solutions provided by the above two patent documents can change the shape of the tracked wheel to a certain extent, it is still a tracked running mechanism, which can only meet the single demand of special road conditions and improve the obstacle-surmounting ability of the tracked wheel. Realize the application of all-terrain and all-road conditions, and cannot freely switch between high-quality road conditions and special road conditions, and there is no all-terrain wheel track that has been published in the newspapers.
