Self-locking deformation wheel with movable spoke

Abstract

The invention discloses a self-locking deformation wheel with a movable spoke. The self-locking deformation wheel is a running gear and comprises self-locking devices of the spoke, an axle, the spoke, a cam, a wheel disc, a rim, a spoke arbor wheel, spoke legs and wheel plates. The self-locking deformation wheel is characterized in that the movable supporting spoke is provided with the self-locking devices, and a plurality of spoke arbor wheel slide shaft holes are radially and uniformly distributed along the wheel disc and the rim and face the center of the wheel to form channel slots of the built-in self-locking devices; equal-height slide shafts which can slide and / or have self-locking functions are fittingly arranged in the various channel slots; one end of each self-locking device is connected with a fixed end of the supporting spoke, and the other end of each self-locking device is connected with a movable end of the supporting spoke; the slide shafts are provided with ball ends and slide along a side surface of a regulating and controlling cam body and side surfaces of position control plates, and accordingly the spoke arbor wheel is locked to form a 'leg' elastically on the outside of the wheel disc. The self-locking deformation wheel with the movable spoke has the advantages that the self-locking deformation wheel can run on flat road surfaces at high speeds, and can also pass soft road surfaces or even road surfaces under stepped conditions, the running performance and the traffic capacity of a vehicle can be effectively improved, and the self-locking deformation wheel can actually replace an existing running mechanism of the vehicle.

[0002] At present, achievements in the field of variable diameter wheels and deformation wheels are rare. The patent disclosure crawler-type multi-road condition automatic deformation wheel CN195837520, the deformation wheel deformation wheel 200710062122 for the electric vehicle for climbing stairs and the deformation wheel for climbing stairs vehicles, and a deformation wheel device 200910249947.5 , these devices are complex in structure and bulky; multi-road condition walking deformation wheel 201020268767, a variable-diameter wheel that automatically adapts to the road surface 201010290940, described in Yang Chun's master's degree thesis "Research on Mobile Mechanism Based on Deformable Wheels" on June 18, 2010 Deformed wheels are unsatisfactory when the load is deformed; the dual-purpose wheel for motor vehicle horizontal driving and ladder 200720188178, and the dual-purpose wheel for motor vehicle horizontal driving and ladder 200820238520 with a clutch mechanism are all added to the original base wheel to form auxiliary wheels. Therefore, two trajectories are formed to make the center of gravity of the wheel drift and become unstable, and the sliding pin is easily damaged due to repeated sliding when climbing the ladder

In this way, either the sliding pin is easily damaged due to repeated sliding, or the expansion and closing operation of each supporting spoke is implicated and restricted when the load wheel needs to be deformed.
