Sweeping Machine and Compensation Method for Uneven Patches
First Claim
1. A sweeping machine, comprising:
- a housing;
at least one circular broom rotatable about an essentially vertical axis of rotation and disposed on the housing;
at least one roller disposed in the housing by way of an axle bracket concentric with respect to the circular broom so that the roller is rotatable about the essentially vertical axis of rotation, and a rolling movement of the roller along a ground surface being transmissible to the circular broom so that the circular broom rotates about the essentially vertical axis of rotation; and
a mechanical coupling device which converts a rotating movement of the roller about the essentially vertical axis of rotation to an axial relative movement between the roller and the housing.

Abstract
A sweeping machine includes a housing, at least one circular broom disposed on the housing so as to be rotatable about an essentially vertical axis of rotation, and at least one roller supported on a ground. The roller is disposed in the housing of the sweeping machine by way of an axle bracket concentric with respect to the circular broom so that the roller may be rotated about the essentially vertical axis of rotation. A rolling movement of the roller along the ground is transmitted to the circular broom so that the circular broom rotates about the essentially vertical axis of rotation. Devices, which convert a rotating movement of the roller about the essentially vertical axis of rotation to an axial relative movement between the roller and the housing, are provided. The method and machine improve the running smoothness of the sweeping machine.

13. A method for operating a sweeping machine to improve a running smoothness, the sweeping machine including a housing, at least one circular broom rotatable about an essentially vertical axis of rotation and disposed on the housing, and at least one roller disposed in the housing by way of an axle bracket concentric with respect to the circular broom so that the roller is rotatable about the essentially vertical axis of rotation, the method comprising the acts of:
-
transmitting a rolling movement of the roller along a ground surface to the circular broom so that the circular broom rotates about the essentially vertical axis of rotation; and
converting a rotating movement of the roller about the essentially vertical axis of rotation to an axial relative movement between the roller and the housing.
