Floor cleaning machine
View Patent ↗A floor cleaning machine includes a cleaning system, a front wheel, two rear wheels, and a drive mechanism. Each of the two rear wheels is independently driven by the drive mechanism. The operator is placed on the machine such that the operator is standing on a platform located along and above the geometrical center axis between the two rear wheels. The maximum vertical distance between the platform and the floor is 200 mm.
1. A floor cleaning machine comprising:
a cleaning system;
a front wheel;
two rear wheels; and
a drive mechanism, wherein each of the two rear wheels is independently driven by the drive mechanism and wherein the operator is placed on the machine such that the operator is standing on a platform located along and above the geometrical center axis between the two rear wheels, wherein the maximum vertical distance between the platform and the floor is 200 mm.
2. The floor cleaning machine according to claim 1 , wherein the front wheel is a castor wheel and the two rear wheels are independently driven by two drive motors.
3. The floor cleaning machine according to claim 1 , wherein the front wheel is a first front castor wheel and further including a second front castor wheel, and further wherein the two rear wheels are independently driven by two drive motors, wherein the distance between the first and second castor wheels is smaller than the distance between the rear wheels.
4. The floor cleaning machine according to claim 1 , wherein the front wheel is a steered wheel driven by a drive motor and wherein the two rear wheels are independently suspended.
5. The floor cleaning machine according to claim 1 , wherein the drive mechanism is a hub motor.
6. A floor cleaning machine comprising:
a cleaning system;
a front wheel;
two rear wheels; and
a drive mechanism, wherein each of the two rear wheels is independently driven by the drive mechanism and wherein the operator is placed on the machine such that the operator is standing on a platform located along a geometrical center axis between the two rear wheels, wherein the maximum vertical distance between the platform and the floor is 200 mm, and further wherein the drive mechanism is positioned forward of the center axis.
