Problems solved by technology

The existing omnidirectional wheels are all driven by belts, and the driving motor is separated from the omnidirectional wheels. The omnidirectional wheels in this transmission mode have low precision, large volume, unstable movement, and the rotation of the omnidirectional wheels is not smooth enough. , can not meet the requirements applied to the current AGV trolley platform

Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention will be further described:

[0035] As shown in the figure, the present invention proposes an integrated omnidirectional wheel, which includes an omnidirectional wheel 1, a transmission 2, and a brushless EC disc motor 3, where the brushless EC disc motor 3 and its transmission 2 are placed Inside the omni-directional wheel 1, the brushless EC disc motor 3 is connected to the transmission 2, and the gear at the output end of the transmission 2 is used as a sun gear to mesh with the internal planetary gear 9 of the omni-directional wheel, and meshes with the internal planetary gear 9 of the omni-directional wheel through the output end of the transmission , to drive the omnidirectional wheel 1 to move, so as to realize the operation of the omnidirectional wheel driven by the motor.

[0036] The output shaft 23 of the brushless EC disc motor transmission is coaxially connected to the Hall sensor 32, and...

Abstract

An integrated universal wheel comprises a universal wheel body, a transmission and a brushless EU disc type motor. The brushless EU disc type motor and the transmission of the universal wheel are placed in the universal wheel body. The brushless EU disc type motor is connected with the transmission. A gear at the output end of the transmission serves as a sun gear to be engaged with a planet gear in the universal wheel body to drive the universal wheel body to move. By the adoption of the integrated universal wheel, the brushless EU disc type motor is fixed into the universal wheel body, and the working efficiency of the brushless EU disc type motor is improved.

Description

technical field [0001] The invention relates to an omnidirectional wheel and a control method thereof, in particular to an omnidirectional mobile device in which a motor and an omnidirectional wheel are integrated. Background technique [0002] At present, omnidirectional wheels are widely used on AGV trolley platforms. Omni-directional wheels are wheels that can be used to build omnidirectional mobile platforms. Its characteristic is that there are rollers at a certain angle to the hub distributed around the hub, the hub is used as the driving wheel, the roller is used as the driven wheel, the driving wheel is driven by the motor, and the rollers roll freely. By controlling the speed combination between the wheels, the device can move directly in any direction without turning. Compared with the ordinary wheel train platform, this kind of omnidirectional wheel mobile platform has higher movement flexibility and can adapt to movement in a narrower space. The existing omnid...
