Switchable planet wheel and caterpillar travel mechanism

Abstract

The invention discloses a switchable planet wheel and caterpillar travel mechanism. The switchable planet wheel and caterpillar travel mechanism is characterized in that a rotary bracket, a first fixing bracket and a second fixing bracket are connected onto a driving shaft, a first supporting wheel is mounted on the rotary bracket, a tensioning wheel hydraulic cylinder is connected with the otherend of the rotary bracket, a tensioning wheel is mounted on a hydraulic shaft of the tensioning wheel hydraulic cylinder, a driving wheel hydraulic cylinder is connected with the other end of the first fixing bracket, a driving wheel is mounted on a hydraulic shaft of the driving wheel hydraulic cylinder, a second supporting wheel is mounted on the second fixing bracket, a guide wheel is mounted at the other end of the second fixing bracket, limit chucks are detachably mounted on two sides of a wheel hub of each of three planet wheels, a detachable caterpillar is wound on the outer sides of the three planet wheels and can be driven by the driving wheel, so that the switchable planet wheel and caterpillar travel mechanism can travel in a wheel and caterpillar manner. The switchable planet wheel and caterpillar travel mechanism has the advantages that the switchable planet wheel and caterpillar travel mechanism can be in a planet wheel set state and a caterpillar combination state, can be switched and used according to different road conditions and has good advancing and obstacle crossing functions adapted to the diversified road conditions.

Description

technical field [0001] The invention belongs to the technical field of all-terrain vehicle traveling mechanisms, and in particular relates to a switchable planetary wheel crawler traveling mechanism. Background technique [0002] The technical problems to be solved by all-terrain vehicles are adaptability to complex environments, good obstacle-surmounting ability and certain driving speed. At present, common all-terrain vehicle traveling mechanisms are divided into leg type, crawler type, wheel type, compound type and the like. The leg-type driving mechanism has good adaptability and strong obstacle-crossing ability, but the structure is too complicated, and there are disadvantages such as low moving efficiency and difficult control; the wheel-type driving mechanism has strong bearing capacity, fast moving speed, simple control and flexible steering, but Due to the small adhesion, the passing performance is poor; the crawler-type driving mechanism has good obstacle-crossing...

Problems solved by technology

The leg-type driving mechanism has good adaptability and strong obstacle-crossing ability, but the structure is too complicated, and there are disadvantages such as low moving efficiency and difficult control; the wheel-type driving mechanism has strong bearing capacity, fast moving speed, simple control and flexible steering, but Due to the small adhesion, the passing performance is poor; the crawler-type driving mechanism has good obstacle-crossing performance and high passing performance, but the driving speed is slow and the wear on the track is too large when turning; the compound traveling mechanism has multiple sets of transmission systems, which are suitable for It is suitable for some special environments, but its structure and control are relatively complicated; in the prior art, a traveling mechanism with a reversible planetary gear set is driven by three planetary gear sets, which has good obstacle-surpassing ability and is suitable for uneven road surfaces. However, the driving mechanism is single, and there are problems such as poor passability on soft and muddy roads, limited barrier functions and bumpy driving, and cannot adapt to various road conditions.
