Definitions
- the present invention relates to spring suspension systems for motor vehicles, and relates more particularly to sheath devices for such springs.
- the document FR2840966 thus proposes, for example, a sheath for part of the end turn of a helical suspension spring, whose opening, located on the inner periphery, makes it possible to protect said end of said spring from the accumulation debris and water, sources of corrosion.
- the sheath proposed by the document FR2840966 further comprises radial and axial bracing means allowing a reproducible centering of the suspension spring on its cup.
- the angular positioning of the end turn, and therefore of the spring, in the sheath is not fixedly defined.
- the angular position of the assembly in the centering cup is not defined, it follows, in particular, that the resultant forces exerted by the helical suspension spring does not have a reproducible orientation with respect to the axis of said spring: in particular, said resultant is not generally not exactly directed along the axis of said spring, which can lead to the exercise of parasitic forces on the vehicle train, and induce, for example, an oversteer of said vehicle.
- the invention aims to provide a device for reproducible angular positioning of the suspension spring in its sheath and on its centering cup, and easy assembly of the assembly.
- the invention achieves its goal by means of a suspension assembly of a motor vehicle, comprising a suspension spring, a sheath intended to be placed on at least part of the end turn of the suspension spring, and a cup of centering on which is placed the sheathed end of the suspension spring, characterized in that the sheath and the centering cup comprise means suitable for
- the appropriate means comprise a first set of means for indexing the angular position of the sheath with respect to the centering cup, and a second set of
- Means for indexing the angular position of the suspension spring relative to the sheath are provided.
- the first set of means comprises a male element capable of cooperating with a suitable complementary female element, the male and female elements being placed respectively on the
- the male element of the first set of means is a lug capable of cooperating with at least a suitable complementary orifice
- the second set of means consists of a stop placed on the sheath.
- FIG. 1 is a diagrammatic perspective view of the end turn of a suspension spring and of the sheath of a device according to the invention
- FIG. 2 is a diagrammatic sectional view of the end turn of the spring and the sheath of a preferred embodiment of the invention
- FIG. 3 is a representation of a centering cup according to one embodiment of the invention.
- FIG. 1 diagrammatically shows the end portion and the end turn 2 of a suspension spring 1, as well as the sheath 3 in a suitable housing, 4, in which at least a portion of the end turn 2 is inserted. .
- the angular position of the suspension spring 1 is indexed relative to the centering cup 7 by appropriate means.
- These means comprise, on the one hand, a first set of means 6 allowing indexing of the angular position of the sheath 3 relative to the centering cup 7, and, on the other hand, a second set of means 8 allowing indexing the angular position of the suspension spring 1 relative to the sheath 3.
- the appropriate means 6 allowing the indexing and the reproducible angular positioning of the sheath 3 with respect to the centering cup 7 comprise at least one male element 61 placed on the sheath 3 or respectively on the centering cup 7, adapted to cooperate with a suitable complementary female element 62, placed on the centering cup 7 or respectively on the sheath 3.
- the male element 61 is a lug secured to the sheath 3, adapted to cooperate by way of example by clipping with a suitable complementary orifice 62 placed on the centering cup 7.
- this lug 61 can be placed on the centering cup 7, said complementary orifice 62 then being placed on the sheath 3.
- the end of said lug 61 has a preferentially conical shape.
- the second set of means 8, permitting the indexing of the angular position of the spring 1 relative to the sheath 3, consists, in the preferred embodiment shown in the figures, of a stop 9 placed at one end 10 of the housing 4 of the sheath 3 in which is inserted at least a portion of the end turn 2 of the spring 1.
- the centering cup 7 comprises on its upper face, namely the face on which the spring bears, a stamp 11 of substantially circular shape, forming a hollow part adapted to receive the sheath 3 by the spring 1.
- the depth of the stamping varies continuously over the entire circumference of the stamping, so that the ramp thus formed can cooperate over the entire length of the sheath 3 and the coil of end 2 of the spring 1.
- the stop 9 thus allows a defined and reproducible positioning of said spring 1 in the housing 4 of the sheath 3 provided for this purpose.
- the appropriate means 6 placed on said sheath 3 and the centering cup 7 allow the operator responsible for mounting to achieve a fixed and reproducible positioning of the assembly " sheath 3 - suspension spring 1 "with respect to the centering cup 7. This results, in particular, in a reproducible orientation of the resultant of the forces exerted by the suspension spring I 3 favorable to a better behavior of the vehicle equipped with such a suspension device.
- the facing of the appropriate means 6 placed on said sheath 3 and the centering cup 7 is made easy by the guiding of the sheath 3 in the ramp formed by the stamping 11, and by the cooperation on the one hand formed ribs on the sheath 3 and boss 13 of the cup 7, and by abutment of the end 10 of the sheath 3 against the stop means 12 formed in the stamping 11.
