发明名称 Floor cleaning machine and method
摘要 A floor cleaning machine having a body in which the body cover assembly is hollow and serves as the recovery solution reservoir; while the lower body assembly, which is also hollow, serves as the cleaning solution tank or reservoir. In addition, the lower body has a recessed area proportioned to receive and secure the batteries required for driving the motors involved in the floor cleaning machine. A trans-axle drive supports the lower body and has a drive wheel at each end powered by a motor differential engaging the axles coupled to the wheels. Together the body and trans-axle drive comprise a modular power unit. Mounting means are provided on the forward portion of the lower body of the power unit for lift arms to be secured to various power floor scrubbers for use on hard floors or a carpet extractor for cleaning carpeted floors. The linkage for the floor scrubber mode and carpet cleaning mode is the same. Such linkage also uses a maximum number of resiliently mounted bushings which, along with the monocoque body and retained fluid movement, cushion against damage by impact under power.
