Abstract
A floor surface conditioning machine, typically a floor scrubbing machine comprising a support structure and supporting wheels, powered scrub brushes beneath the support structure, a brush carriage connecting the scrub brushes to the support structure, and a frictional motion dampener between the brush carriage and the support structure to dampen vibration of the brush carriage caused by the scrub brushes, this frictional motion dampener having a pair of friction members spaced from each other and astraddle a fixed member, and a pair of biasing springs biasing the pair of friction members against opposite sides of the fixed member. The fixed member includes a cam track and the friction members have a cam follower therebetween to follow the cam track during vertical movement of the brush carriage.
