MOBILE APPARATUS, PARTICULARLY AN AUTONOMOUSLY MOBILE FLOOR CLEANING DEVICE

摘要

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.

主权项

1. Mobile apparatus (1), particularly an autonomously mobile floor cleaning device, having a chassis (2) and a plurality of wheels (3), wherein at least one wheel (3) is driven, and the driven wheel (3) is connected to the chassis (2) via a suspension element (5) that supports wheel (3) and is movable relative to the chassis (2),
wherein the wheel (3) for support on a subsurface (6) over which the mobile apparatus (1) can travel is influenced by a spring (7) exerting a spring force and can be retracted and extended relative to the chassis (2) with the aid of the suspension element (5), 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 (3) is extended farther.
