专利汇可以提供Aircraft landing gear专利检索，专利查询，专利分析的服务。并且This invention provides an aircraft landing gear in which a bogie axle is mounted horizontally in bearing means at the bottom of a vertical strut which incorporates a shock absorber cylinder. The bogie beam extends in either direction from the bearing means and the latter is constructed for minimal resistance to rolling movement, preferably by incorporating a spherical bearing surface. Resistance to rolling movement is provided by two torque linkages extending between the vertical strut above the shock absorber piston and the ends of the bogie beam.，下面是Aircraft landing gear专利的具体信息内容。

权利要求

1. An aircraft landing gear, comprising: a substantially vertical strut incorporating at its lower end a shock absorber cylinder, a shock absorber piston in said shock absorber cylinder adapted for reciprocal movement therewithin, a bogie axle mounted horizontally in bearing means in said shock absorber piston, a bogie beam mounted on said bogie axle at a location intermediate the ends of the bogie beam, wheel means mounted at either end of the bogie beam, a first torque linkage consisting of a first upper V-link and a first lower V-link pivotally joined together at their apices, the first upper V-link having its base pivoted to said strut, the first lower V-link having its base pivoted to the bogie beam at a point intermediate said location and one end of the bogie beam, a second torque linkage consisting of a second upper V-link and a second lower V-link pivotally joined together at their apices, the second upper V-link having its base pivoted to said strut, the second lower V-link having its base pivoted to the bogie beam at a point intermediate said location and the other end of the bogie beam, said bearing means having insufficient roll-resistant strength to resist by itself the normal rolling movement of the bogie beam about a roll axis extending longitudinally of the bogie beam, whereby the major resistance to such rolling movement is provided by the first and second torque linkages.

2. An aircraft landing gear as claimed in claim 1, in which said bearing means comprises a bearing seat fixed to the shock absorber piston and defining a spherical bearing surface, the bogie axle having a spherical bearing seated against said spherical bearing surface.

3. An aircraft landing gear as claimed in claim 2, in which said wheel means consists of two wheel axles, one at either end of the bogie beam, each wheel axle supporting two wheels.

4. An aircraft landing gear as claimed in claim 3, in which the dimension of said bearing means in the longitudinal direction of the bogie axle is small compared with the dimension through the shock absorber piston.
