Abstract
A vehicle suspension strut 1 comprising a telescopic hydraulic damper 2 and coaxial main suspension spring 3 is fitted with a brake pressure control valve 23. The control member 22 of the valve is acted on by a lever 20 pivotally mounted on a bracket 18 fast with the damper body. The lever 20 supports the end of a tubular support 7 which is movable axially of the damper body and which carries the support plate 9 for the main suspension spring. A compensating spring 12 acts between a ring 13 supported on bracket 18 and an adjustable collar 14 mounted on the tubular element. The compensating spring 12 reacts part of the main suspension spring load onto the damper body, and the remaining suspension spring load is transferred to the body via the lever 20 which distributes the force equally between the bracket 18 and the control member 22.
Claims8
A suspension strut assembly for a vehicle comprising a telescopic damper including a body, a main suspension spring coaxially surrounding said damper body, a tubular support also coaxially surrounding the damper body and including an abutment for one end of said main suspension spring, said support being mounted on the damper body and being guided thereon for axial movement relative to the damper body in response to the loading on said main suspension spring, a brake pressure control valve assembly, said valve assembly including a valve body mounted on the side of said damper body and being relatively immovable with respect thereto and a valve control member extending from said valve body, and means, separate from said abutment for said main suspension spring coupling said support to said control member and to said damper body, said coupling means being constructed and arranged that part of the load on the main suspension spring is transmitted through it and said support to said valve control member and the remainder of said load is transmitted through said coupling means and said support to the damper body whereby the suspension spring load exerted on said control member is independent of any change in position, during use, of said main suspension spring relative to said damper body.
