Definitions
- the present invention claims the priority of French application 2209549 filed on September 21, 2022, the content of which (text, drawings and claims) is here incorporated by reference.
- the present invention relates to a suspension spring support for a motor vehicle.
- a suspension spring support is a part positioning, for example, a rear axle shock absorber spring on the underbody of the vehicle.
- the present invention aims to improve the rigidity of such a support.
- the invention proposes a suspension support comprising a patina intended to bear against a first face of a spar of a chassis for a motor vehicle.
- one edge of the support plate is extended by an appendage intended to bear against a second face of the spar, the second face of the spar being adjacent to said first face.
- the suspension support has increased rigidity.
- the appendage extending the plate forms an angle with the plate whose value is between 80° and 100°, preferably of the order of 90°.
- the plate includes a projection intended to hold one end of a helical spring.
- the protrusion is cylindrical or substantially cylindrical in shape.
- the invention also relates to a chassis for a motor vehicle, comprising a spar on which is mounted a support for a suspension spring as described above.
- the spar comprises a rebate bearing against at least two faces of the spar covered by the support.
- the profile of the spar is “u” shaped or substantially “u” shaped.
- the rebate has a stair-step profile.
- the support plate is welded to the first face of the spar, at the level of a step or a riser formed by the rebate.
- the appendage of the support is welded to the second face of the spar, at the level of a step riser or a step formed by the rebate.
- the chassis comprises a helical spring, one end of which bears against a support as described above.
- the appendage present at the level of the support plate is inserted at least partially into the helical spring.
- the chassis comprises a multi-link rear axle, linked to a second end of the helical spring.
- the invention also relates to a motor vehicle comprising a chassis as described above.
- FIG. 1 illustrates a perspective view of a chassis comprising a spring support according to the invention
- FIG. 2 illustrates a perspective view of a chassis comprising a spring support according to the invention, on which a helical spring is present;
- FIG. 3 illustrates a perspective cross section of the chassis shown in Figure 1;
- FIG. 4 illustrates a perspective view of a chassis represented by Figure 1, comprising a multi-link rear axle linked to a support according to the invention via a helical spring.
- the invention proposes a support for a motor vehicle suspension spring whose rigidity is increased.
- Figure 1 illustrates a non-limiting exemplary embodiment of the invention of a support for a suspension spring.
- the support 2 consists of a plate 4 bearing against a first face 6 of a spar 8 of a chassis 10 for a motor vehicle.
- An upper face 12 of the plate 4 includes a protrusion 14.
- the protrusion is cylindrical or substantially cylindrical in shape and extends perpendicularly or substantially perpendicularly to the upper face 12.
- the protrusion 14 is intended to be inserted into a helical spring 16, at the level of a first end 18 of said spring.
- the support 2 is remarkable in that one edge of the plate 4 is extended by an appendage 20, intended to bear against a second face 22 of the spar 8.
- the second face 22 is adjacent to the first face 6 of the spar.
- the appendix is identical or similar in shape to the plate.
- the appendix 20 forms an angle with the plate 4, the value of which is between 80° and 100°, preferably of the order of 90°.
- the support 2 has the shape of a square in order to bear against two adjacent faces of the spar 8.
- the particular shape of the support 2 gives it increased rigidity compared to the supports for suspension springs used in the automobile sector.
- the plate 4 and the appendix 20 form a single part.
- the support is preferably made from a metallic material.
- the profile of the spar 8 is similar or substantially similar to a “U”.
- the spar comprises a rebate 24 bearing against at least two faces of the spar which are covered by the support 2.
- the rebate 24 is present in the spar 8.
- the rebate has several faces arranged so as to form a stair-step profile.
- the plate 4 of the support is welded to the first face 6 of the spar 8, at the level of a step 26 formed by the rebate, and the appendage 20 of the support is welded to the second face 22 of the spar at the level of a riser 28 of the rebate 24.
- the welding points allowing the support 2 to be held against the spar 8 are made at the level of a wall composed of one face of the spar and a part of the rebate.
- the welding points are then formed at areas of the spar characterized by extra thickness and therefore increased rigidity.
- the presence of the rebate in the spar therefore makes it possible to locally increase the rigidity of the spar, in order to ensure better retention of the support on the spar 8 by a welding technique for example, without it being necessary for this. to increase the thickness of the spar 8.
- the invention thus allows better retention of the support on a spar, in a more economical manner.
- the invention also relates to a chassis 10 for a motor vehicle, as illustrated in Figure 4, comprising a helical spring 16, a first end 18 of which bears against a support 2 according to the invention, and a second end 30 of the spring is linked to a multi-link rear axle 32.
