Description

Technical Field

[0001] The invention relates to the field of rotating wheels, in particular to an omnidirectional rotating wheel and a vehicle equipped with the rotating wheel. Background Art

[0002] It is difficult for engineering vehicles to park or turn around in a narrow space, especially in warehouses, where forklifts, scrap trucks, etc. are affected in turning around. In order to solve these problems, various forms of omnidirectional mobile technologies have appeared on the market, with wheels that can rotate at different angles; For example, the Chinese invention patent with the current publication number CN108819612A discloses an omnidirectional drive wheel, including an omnidirectional drive wheel body and a rubber-coated wheel, a support cover is arranged above the omnidirectional wheel body, a large synchronous pulley and a small synchronous pulley are rotatably arranged on the support cover, the small synchronous pulley is driven by the output of the travel drive motor, and the small synchronous pulley drives the large synchronous pulley, and finally the large synchronous pulley drives the rubber-coated wheel to rotate through the reduction mechanism, and in addition, the outer ring teeth are arranged on the slewing support member through the meshing of the steering drive gear on the steering drive motor, so as to drive the rubber-coated wheel to rotate 360° without dead angles; Although the above-mentioned omnidirectional drive wheel can realize 360° steering of a single drive wheel, the vehicle is generally equipped with four rotating wheels, each of which adopts a separate steering drive structure, which increases the cost and requires separate control of the steering of each rotating wheel, which is not convenient for steering control during vehicle driving.

[0003] The existing solutions on the market mainly include several forms. One is a car that can park laterally, which is characterized by the fact that both the front and rear wheels can rotate 90 degrees. The second is the design of a slag truck. The characteristic of this type of vehicle is that the front wheels can also rotate 90 degrees, but the rear wheels cannot rotate more than 90 degrees due to structural limitations. This is inconvenient for the driver to operate. When turning during normal driving, only the front wheels need to be controlled to rotate, and the rear wheels do not need to rotate. When moving the vehicle sideways, the steering of the front and rear wheels needs to be controlled synchronously, and the steering angles need to be synchronized.

A vehicle according to claim 8, characterized in that: The vehicle steering method comprises the following steps: Step 1: Control the steering wheel (b1) to rotate to drive the connecting shaft (43) of the front omnidirectional steering wheel to rotate through the transmission shaft assembly (b6); the connecting shaft (43) rotates through the driven bevel gear (44), the transmission shaft four (45) and the worm (46) to drive the worm wheel (47) to rotate; the worm wheel (47) drives the sleeve (58) to rotate; the sleeve (58) drives the rotating frame (56) and the running wheel (57) to turn, and the running wheel (57) rotates in all directions; Step 2: The steering angle of the sleeve (58) is monitored by the steering angle detection component (59), and the steering angle of the running wheel (57) of the front omnidirectional steering wheel is monitored. The connecting shaft (43) of the rear omnidirectional steering wheel is driven by the rear wheel steering drive motor (b5), so as to drive the running wheel (57) of the rear omnidirectional steering wheel to steer, and the steering of the running wheels (57) of the two sets of omnidirectional steering wheels is synchronously controlled.
