An aircraft landing gear 1 comprises a sprung arm 10 mounted to a main pivot 11 and carrying one or more wheels 14. A swinging link 50 has a first end which is pivotally coupled to a crank arm 20 of the sprung arm via a first swinging link pivot 51 and a second end which is pivotally coupled to a transfer arm 33 via a second swinging link pivot 52. The transfer arm is attached to each of a plurality of leaf springs 30. The leaf springs are arranged to provide a resilient biasing force via the transfer arm and the swinging link which opposes rotation of the sprung arm about the main pivot. Each leaf spring only absorbs a portion of the landing loads, so load and stress levels in each individual spring are lower. The swinging link enables the leaf springs to be positioned remotely from the sprung arm, in a suitable position to optimise the use of space and distribute loads efficiently into the airframe. |
