Liftable variable track structure and wheel-track composite equipment

Abstract

The invention provides a liftable variable track structure and wheel-track composite equipment. The liftable variable track structure comprises a track, a driving wheel arranged in the track, and at least two groups of loading wheels, the driving wheel is fixedly mounted on a vehicle body, and the loading wheels are mounted on loading wheel shafts; and the track structure further comprises a supporting arm, one end of the supporting arm is connected with the loading wheel shaft, the other end of the supporting arm is connected with a supporting shaft, and the supporting shaft is installed on a support fixedly connected with the frame. The track structure further comprises a lifting mechanism for driving the supporting arm to swing up and down around the axis of the supporting shaft to drive the loading wheels to retract and release, the loading wheels are lower than the driving wheel when being in a descending state, and the track is of a triangular arrangement structure and is prevented from integrally sinking into mud flat and muddy road surfaces, so the track and wheel driving force help the vehicle is helped to escape from mudflat and muddy road surfaces, and the cross-country obstacle crossing capability of the track can also be improved. When the loading wheels are in a folded state, the track is of a horizontal arrangement structure, the ground clearance is guaranteed, and the trafficability of the vehicle on the land is improved.

Description

technical field [0001] The invention relates to the technical field of wheel-track compound equipment, in particular to a liftable modified track structure and wheel-track compound equipment. Background technique [0002] Wheel-track composite equipment, such as an amphibious transport vehicle with a track structure and wheels, can be driven independently by the wheels or cooperatively driven by the wheels and track structures according to the specific land working conditions of the vehicle. [0003] For example, the Chinese invention patent application with the application publication number of CN112918204A discloses a motor-carrying equipment and its floating crawler lifting mechanism, including a car body and a crawler running mechanism, and the crawler running mechanism is retractably assembled on the car body through the lifting mechanism. The lifting mechanism includes a supporting shaft and an oil-pneumatic spring. On the supporting shaft, an input crank arm and an ou...

Problems solved by technology

[0005] The purpose of the present invention is to provide a variable crawler track structure that can be lifted to solve the problems that the existing crawler track as a whole is easy to sink into the beach and muddy road, cannot cooperate with the driving force of the wheels, and the height of the crawler track participating in obstacle surmounting is limited; the present invention The purpose of the invention is also to provide a wheel-track composite equipment to solve the problem that the crawler track of the existing vehicle is easy to sink under the beach and muddy road as a whole, the driving force of the wheels cannot be coordinated, and the height of the track is limited for participating in obstacle surmounting.
