Drive system for a cleaning unit, and cleaning unit
First Claim
1. A drive system for driving an automatic cleaning unit, the drive system comprising:
- a carrier unit;
a drive motor attached to the carrier unit;
a drive shaft rotatably disposed on the carrier unit and drivable by the drive motor;
a forward propelling unit disposed on the drive shaft and rotatable about the drive shaft through a driving axle that is coupled to the drive shaft through a gear unit; and
a cleaning element;
wherein the forward propelling unit is coupled to the drive shaft so as to generate a forward propelling movement in perpendicular relation to a longitudinal direction of the drive shaft and to cause the forward propelling unit to rotate relative to the carrier unit whenever the forward propelling movement is obstructed;
wherein the carrier unit supports a mounting element that encloses the forward propelling unit;
wherein the cleaning element is attachable to the mounting element; and
wherein the carrier unit is constructed so as to rotate the cleaning element about the forward propelling unit when the forward propelling unit generates the forward propelling movement.
