<p>An aircraft landing gear 10 includes a bogie beam 12 and an axle 14 pivotally connected to the bogie beam and steerable by means of a hydraulic actuator 18. The axle pivots about a pivot pin 16 and moves with a linkage 20. The linkage 20 cooperates with a locking member 40 such that movement of the axle invokes movement of the locking member, said movement of the locking member defining a swept volume. A locking mechanism 60 is coupled to the bogie beam and includes first and second cam members (65a,65b, fig 3). The locking mechanism being arranged to move the cam members between locking positions where cam members are engaged with cam surfaces 41b 41c on opposing sides of the locking member and in which position the locking mechanism is arranged to lock the locking member in a predetermined position and non-locking positions, where the locking mechanism is arranged to permit movement of the locking member. The cam members are located at the end of L-shaped arms (64a,64b, fig 3) which are moved by an actuator 68.</p> |
