Mobile apparatus, particularly an autonomously mobile floor cleaning device
First Claim
1. Mobile apparatus, having a chassis and a plurality of wheels,wherein at least one wheel is driven, and the driven wheel is connected to the chassis via a suspension element that supports the driven wheel and is movable relative to the chassis,wherein the driven wheel for support on a subsurface over which the mobile apparatus can travel is influenced by a spring exerting a spring force and can be retracted and extended relative to the chassis with the aid of the suspension element, andwherein the spring force is adjustable independently of an increase or decrease in the spring force caused by such extension or retraction and independently of the degree to which the mobile apparatus is tilted.

Abstract
A mobile apparatus, particularly an autonomously mobile floor cleaning device, has a chassis and wheels, wherein at least one wheel is driven, and the driven wheel is connected to the chassis via a suspension element that supports the wheel and is movable relative to the chassis. In order to create an alternative mobile apparatus for negotiating an obstacle, the wheel for support on a subsurface over which the mobile apparatus can travel is influenced by a spring exerting a spring force and can be retracted and extended relative to the chassis with the aid of the suspension element, wherein the spring force is adjustable independently of an increase or decrease in the spring force caused by such extension or retraction, and in particular may be increased as the wheel is extended farther.
