Crawler wheel capable of realizing interconversion between wheel type state and crawler type state

Abstract

The invention belongs to the technical field of vehicle running, and discloses a crawler wheel capable of realizing interconversion between a wheel type state and a crawler type state. The crawler wheel comprises a driving and braking assembly, a crawler belt, a retainer, an inducer, a loading wheel and an actuator. Due to the structure of combining the driving and braking assembly, the crawler belt, the retainer, a tensioning wheel, a carrier wheel, the inducer, the loading wheel and the actuator, deformation of the retainer can be controlled by virtue of the actuator, and conversion from the wheel type running state to the crawler type running state and conversion from the crawler type running state to the wheel type running state can be realized, so that the running state can be conversed according to the requirement of vehicle running. On soft and slippery pavements, the crawler wheel can be converted into crawler running to increase the ground contact area and improve adhesion and traction force so as to improve the trafficability; and on flat and hard pavements, the crawler wheel can be converted into wheel type running to reduce power consumption and increase the running speed, so that implementation of high maneuvering capability is benefited.

Description

technical field [0001] The invention relates to a vehicle running device, which belongs to the technical field of vehicle running. The invention proposes a crawler wheel that can realize the conversion between a wheeled state and a tracked state based on the deformation of the cage and the rotation of the track ring. The high-efficiency characteristics of high-speed driving and the high-passability of crawler walking are conducive to giving full play to the advantages of wheeled or crawler-type vehicles, allowing the vehicle to take into account both high-speed driving and high passability. Background technique [0002] In the history of continuous development of vehicle walking components, wheels and tracks have become the two main ways for vehicles to walk, namely wheeled and tracked. But both ways of walking have advantages and disadvantages. [0003] The use of wheels has a history of 6,000 years from today. Although there is no clear record of the invention of the whee...
