Wheel suspension for suction robot, has primary semi-trailing arm and secondary semi-trailing arm on which forces caused by driving of wheel are applied during movement of wheel axle relative to chassis downwardly and upwardly, respectively

摘要

The wheel suspension (5) has a wheel axle (4) and a chassis (6) at which a primary semi-trailing arm (I) is fastened. The primary semi-trailing arm is pivotably connected by a linkage (8) with a secondary semi-trailing arm (II) in a movable manner. The secondary semi-trailing arm is pivotably mounted at a pivoting stop (7) of the chassis. Forces caused by driving of a wheel (3) are applied on the primary semi-trailing arm or are applied on the secondary semi-trailing arm during movement of the wheel axle relative to the chassis downwardly and upwardly, respectively.
