FLOOR CLEANING OR BURNISHING MACHINE PIVOT SUSPENSION

摘要

A pivot suspension has two separate wheels and a channel, which has two ends axially extending across a floor cleaning or burnishing machine. One wheel is attached to a first end of the channel and the other wheel is attached to a second end of the channel. The pivot suspension further has a pivot rod that is pivotably attached to and is in line from front to rear with the machine. The pivot rod is fixedly connected to the channel at a location between the two channel ends. As a result, the wheels and channel are pivotably attached to the machine, by way of the pivot rod. In combination with at least one wheel or caster that is attached to a frame of the machine, the two channel wheels form three points of contact with a floor, even if there is dirt, debris, and unevenness on or in the floor.
