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

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.
