Abstract

802,021. Aircraft undercarriages. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Dec. 13, 1955 [Jan. 13, 1955], No. 35804/55. Class 4. In a retractable undercarriage for aircraft wherein means are provided to adjust the position of the wheel with respect to the leg to avoid obstacles during retraction, the leg J contains an inner sleeve C which carries at its lower end an arm C<SP>1</SP> to which is pivoted a further arm B carrying the wheel R. A shock absorber 1 is connected at its lower end to arm B and at its upper end to a plunger 3 within sleeve C, said plunger having a connection with a link 6 pivotally connected at 8 to a bell-crank 7 mounted on a pivot 5 carried by an extension of the leg J. One arm of bell-crank 7 is formed with a cam-slot 9 which co-operates with a pin 10 on the lower end of an arm 11 which is fixed in the aircraft and carries the retraction pivot 12 of the undercarriage. During retraction of the undercarriage, co-operation between pin 10 and cam slot 9 causes the bell crank to rotate with respect to leg J and thereby draw plunger 3 and shock absorber 1 upwardly within sleeve C to cause the axis of wheel R to follow the path T in order that the wheel may avoid the structural obstacles N.
