Aircraft undercarriage of tilting-beam type and of reduced bulk

An undercarriage having a longitudinal axis for an aircraft, comprising a casing which is connected to the structure of the aircraft and inside which are arranged a shock absorber means having one end to which is hinged a beam equipped at each of its ends with rolling means, the shock absorber means including:

• a hollow cylinder slidable inside the casing by a first end and projecting by a second end;
• a plunger stem of a first cross-section slidable at the first end of the hollow cylinder;
• a piston of a second cross-section slidable at the second end of the hollow cylinder, so that the latter, the plunger stem, the piston and the casing define at least one closed chamber which is variable as a function of the displacement of the hollow cylinder and of the piston, this chamber having at least one volume of compressible fluid cooperating with at least one respective volume of incompressible fluid, means of throttling being arranged inside the chamber whilst the second end of the hollow cylinder is provided with a hinge member comprising a hingepin at a point situated in front of and beyond the said second end, this pin serving for the hingeing of the beam at a point differing from its centre, the beam being connected to the piston by a connecting-rod hinged firstly to the said piston and secondly to the beam at a point differing from the point of hinge.
