Abstract
Abstract A motor vehicle suspension unit with a device for varying the static load of the suspension, comprising a pair of elements telescopically guided one within the other and a spring resting with its opposing ends on stops rigid with the one and other of the telescopic elements respectively. One of the stops consists of a sleeve able to be rotated coaxially to one telescopic element and provided with cam means for its axial positioning in accordance with the angular position assumed. The sleeve comprises peripherally a plurality of axial notches. A pair of ring elements is supported on the ring. One sleeve is provided with a radial lever and an axial projection arranged to penetrate into one of the notches and the other acts as a support for a spring urging the projection into one of the axial notches. The ring is disengageable from the sleeve to rotate the lever into a position in which it does not cause trouble for the passenger.

Claim 1
Independent Claim
232 words
A motor vehicle suspension unit of the type including means for varying the static load of the suspension, comprising a pair of cylindrical elements telescopically guided one within the other and each having means rigid therewith defining supporting plates, a coil compression spring having ends retained by said supporting plates, a sleeve member surrounding one of said cylindrical elements and angularly and axially adjustable thereon, said sleeve member having an inner cam surface defining recesses axially and radially spaced from one another, a lug member rigid with said one cylindrical element for engagement into said recesses, and means for positive displacement of said sleeve member thereby causing said lug member to engage a different one of said recesses for adjusting the static load of the suspension, wherein, according to the improvement, said sleeve member has an annular shoulder defining a plurality of axial notches arranged angularly spaced apart and said means for positive displacement of said sleeve member comprise a ring element surrounding said sleeve member and having a radial operating lever and at least an axial projection for engagement with said axial notches, said means further including a spring urging said axial projection into one of said notches, whereby said ring element is axially displaceable with respect to said sleeve member and disengageable therefrom for bringing said operating lever into a non-annoying rest position after positive displacement of said sleeve member.
