Wheel module with at least one wheel; has drive motor with drive shaft and steering motor to steer wheel about steering angle, where one shaft is hollow and other shaft rotates in it

摘要

The module has a drive motor (110) to drive the wheel through a drive shaft (170) and a steering motor (120) to steer the wheel about a steering angle. One of the steering shaft or the drive shaft is formed as a hollow shaft, in which the other shaft is arranged so that it can rotate. Preferably, the support point of the wheel is offset laterally relative to the steering axis and transversely to the rotation direction of the wheel. An Independent claim is included for a method for electronic coupling of the wheel module to additional wheel modules.
