Abstract
The invention concerns a shock strut for a MacPherson wheel suspension comprising a shock absorber with a body (21) and a rod (22). A coil spring (24) is mounted on a lower spring retainer (23) integral with the shock absorber body (21). The first turn of the spring (24) of the MacPherson strut can be immobilized on and relative to the lower spring retainer (23) in various predetermined positions on the lower spring retainer (23).
Claims10
A MacPherson strut for a MacPherson wheel suspension, comprising a shock absorber with a body (1, 11, 21) and a rod (2, 12, 22);
- said rod (2, 12, 22) being surrounded by a coil spring (4, 14, 24);
- said coil spring (4, 14, 24) being mounted between a lower spring retainer (3, 13, 23) non-pivotally secured to the shock absorber body (1, 11, 21) and an upper spring retainer through which the shock absorber rod passes;
- wherein said MacPherson strut comprises means capable of immobilizing a first turn of the spring (4, 14, 24) on and with respect to the lower spring retainer (3, 13, 23) in a plurality of predetermined positions on the lower spring retainer (3, 13, 23), said predetermined positions defining a direction of translation that allows adjustment of an inclination of the spring with respect to an axis of the shock absorber.
