| 摘要 |
The invention relates to a floor-surface treating machine (1) comprising a chassis (2), on which at least three wheels (4, 5, 6) are mounted, these wheels bearing against the floor surface (3) and being capable of rolling therealong. In each case one (4) of the wheels is driven by drive means, so as to enable the machine to be moved over the floor surface (3), and one (4) of the wheels is steerable so as to enable the machine (1) to be steered along a path adapted for the displacement of a number of rotatable floor-treating devices (7, 8, 9). When seen in a straight movement direction (F), the driving and steering wheel (4) is the centermost wheel, whereas one wheel (5) mounted on one side of the machine is fixed and rotates in the direction of machine movement, and a wheel (6) mounted on the other side of the machine is pivotably mounted. |
