To provide a connecting means with ground having a wheel 2 fitted to a wheel support body 3 and the wheel support body 3 fitted to a support member 5 by a vertical suspension device.

The support member 5 is fitted to a chassis 1 by a load support arm 70, the support member is articulatedly joined with one side of the arm along a geometrical axis AA with an approximately horizontal camber, and the other side of the load support arm is connected to the chassis along an approximately vertical geometrical axis AK. A camber control rod 71 is articulately joined with the support member 5, the camber control rod 71 is separated from the geometrical axis AA of the camber and moves laterally to the chassis 1, and a member 6 forming a triangle connects the load support arm 70 to the chassis 1 so as to control a moment with around an approximately vertical geometrical axis AK.
