Abstract
The invention concerns a method and a device for mounting a MacPherson strut suspension radius rod, comprising steps which consist in: inserting the elements forming the control rod beneath a mounting head having at least a tilting degree of liberty; bringing the control rod top end alongside a portion of the mounting head; compressing the spring by the relative movement of the mounting head with respect a locking member engaged in its prestressed spring, when the mounting head portion comes to a stop and when the shock-absorber rod moves beyond the upper spring retainer.
Claims9
A method of mounting a MacPherson suspension strut comprising a shock absorber having a body and a rod, and a coil spring to be compressively preloaded between a lower spring retainer secured to said shock absorber body and an upper end of said suspension strut including an upper spring retainer to be secured to an upper end of said shock absorber rod, said method comprising the steps of:
- a) providing a mounting device having a shock absorber holding means and a mounting head which are movable one with respect to the other along a spring compression direction, said mounting head comprising a part having at least one degree of freedom in tilting about an axis transverse to said spring compression direction and at least a limit stop for stopping said part in a chosen predetermined orientation corresponding to a position in which said upper spring retainer is centered in a predetermined way with respect to said shock absorber rod;
- b) introducing the suspension strut to be mounted into said mounting device by engaging the shock absorber body of said suspension strut in said shock absorber holding means, and placing the upper end of said suspension strut under said mounting head;
- c) mating the upper end of said suspension strut with said part of the mounting head;
- d) compressing the spring of said suspension strut by causing a relative movement between said shock absorber holding means and said mounting head along said spring compression direction, until said part of said mounting head comes into abutment with said limit stop and said shock absorber rod protrudes through a central hole of the upper spring retainer;
- and
- e) securing the upper end of said shock absorber rod lo said upper spring retainer.
A device for mounting a MacPherson suspension strut comprising a shock absorber having a body and a rod, and a coil spring to be compressively preloaded between a lower spring retainer secured to said shock absorber body and an upper end of said suspension strut including an upper spring retainer to be secured to ;m upper end of said shock absorber rod, said mounting device comprising:
- a) a shock absorber holding means for holding the body of the shock absorber of the suspension strut to be mounted;
- b) a mounting head for accommodating the upper end of said suspension strut, said shock absorber holding means and said mounting head being movable one with respect to the other along a spring compression direction;
- wherein said mounting head comprises a body and a part having at least one degree of freedom with respect to the body of said mounting head, said part being able to tilt about an axis transverse to said spring compression direction, and said mounting head body having a limit stop for stopping said part in a chosen predetermined orientation corresponding to a position in which said upper spring retainer of said suspension strut, when mated with said part and when the spring of said suspension strut is compressed to such an extent that the shock absorber rod of said suspension strut protrudes through a central hole of said upper spring retainer, is centered in a predetermined way with respect to said shock absorber rod.
