Oleopneumatic suspension with telescopic leg for vehicles

An oleopneumatic suspension having a substantially vertical telescopic leg for use in a vehicle steering wheel assembly, comprising:

• a lower element for supporting a vehicle wheel connected to the structure of the vehicle by a substantially transverse articulated lever;
• an upper element articulated to the structure of the vehicle and serving to guide the lower element, the upper and lower elements being slidable in relation to one another along an axis, and
• means for causing a pressurized liquid to separate the two elements from one another, the improvement being that
• one of the two elements includes an elongated tubular member filled with said pressurized liquid and having at one end a bore sealed by an elongated piston of no greater diameter than said bore throughout its length so that said piston can slide freely away from said elongated tubular member along its longitudinal axis without liquid dampening, said pressurized liquid serving only to damp shock forces which act to slide said piston toward said elongated tubular member,
• whereas the other element includes a cylinder surrounding the tubular member and coaxial therewith, this cylinder being closed at one end by a bottom against which said piston bears.
