Abstract

Abstract A vehicle suspension unit which comprises a telescopic hydraulic damper and a coil compression spring fitting over the body of the damper and abutting at one end against a collar on the piston rod of the damper and at the other end against a sleeve adjustably surrounding the body, the sleeve engaging the body through the intermediary of cam means such that angular movement of the sleeve around the body causes adjustment of the axial position of the sleeve on the body, the cam means positively locating the ring in at least two different positions of adjustment, mainly characterized in that the sleeve comprises an inner portion (4) whose end face is shaped to constitute a cam surface (7) engaging projections (h) on the body of the damper and an outer portion (3) surrounding the inner portion and projecting axially beyond the shaped end face thereof.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 144 words
In a vehicle suspension unit, comprising: a telescopic hydraulic damper including a cylindrical body, a piston working in said body and a piston rod connected to said piston; and a coil compression spring fitting over said damper body and abutting at one end against a collar on said piston rod and at the other end against a sleeve surrounding said damper body and angularly and axially adjustable thereon, said sleeve engaging said body through the intermediary of cam means which cause axial adjustment of said sleeve in response to angular adjustment thereof and which positively locate said sleeve in each of at least two different positions of adjustment, the improvement which comprises said sleeve having a radially inner portion having an end face constituting a cam surface, and a radially outer portion surrounding said inner portion and projecting axially beyond said end face thereof.
