<p>This device for locking a pneumatic suspension system of the bellows type comprises a hydraulic ram (1), arranged axially inside two of the suspension bellows (2), between the support points of the latter between an axle (15) and the chassis (11) on either side of the latter. The said ram (1) is a single action hydraulic ram connected to a low pressure fluid reservoir by way of a slide directional control valve adapted to selectively assume a first position in which it makes the said connection by way of a non-return valve only allowing outflow from the ram, a second position in which it makes the said connection directly and freely, and a third position in which the said ram is isolated from the said reservoir. <IMAGE></p> |
