Abstract
An aircraft undercarriage includes an upper element for connecting to an aircraft structure and a lower element carrying an axle. The lower element is mounted to be movable in translation relative to the upper element along a longitudinal axis, and a shock absorber is arranged to damp movements in translation of the lower element relative to the upper element. First and second portions of a spring are connected respectively to the upper element and to the lower element so that during movement in translation of the lower element relative to the upper element, the spring opposes any turning of the lower element relative to the upper element about said longitudinal axis.

An aircraft undercarriage comprising an upper element configured to be connected to an aircraft structure, a lower element carrying an axle, said lower element being mounted to be movable in translation relative to the upper element along a longitudinal axis of the upper element, and a shock absorber configured to damp movements in translation of the lower element relative to the upper element, wherein the undercarriage includes a spring having first and second portions that are spaced apart from said longitudinal axis, the first portion of the spring being secured to the upper element and the second portion of the spring being secured to the lower element in such a manner that during movement in translation of the lower element relative to the upper element the spring opposes any turning of the lower element relative to the upper element about the longitudinal axis,
- wherein said spring is a helical spring that is compressible along a longitudinal axis of the spring by moving the first portion closer to the second portion, and
- wherein the first portion of the spring is secured to the upper element via a portion of the upper element that projects outwards from the upper element, radially relative to the longitudinal axis of the upper element, and wherein the second portion of the spring is secured to the lower element via a portion of the lower element that projects outwards from the lower element, radially relative to the longitudinal axis of the upper element.
