Definitions

  • ABSTRACT Foreign Application Priority Data Leaf spring having at least one lead and a fastening clip Aug. 4, 1970 France 7028761 in the centre part of the leaf or leaves. A corrugation extending throughout the width of the leaf or leaves ad- [52] US. Cl. 267/52 joins twocorrugations in the clip on each side of the [51] Int. Cl. F161 l/22 leaf or assembled leaves. [58] Field of Search 267/52 4 Claims, 6 Drawing Figures The present invention relates to vehicule suspension leaf springs comprising at least one leaf and interposed between the suspended part and the unsuspended part of the vehicule.
  • An object of the invention is to provide a centering and fastening device for a leaf spring which does not reduce the section of the spring or result in sudden variations which permits the utilization of relatively short clips .and which also permits the submission of the spring to a preforming operation over its entire length so as to ensure a substantially prolonged spring life.
  • the invention provides a leaf spring comprising at least one leaf and a detachable fixing clip disposed in the centre part of the spring, wherein the or each leaf has in its fastened or clipped centre part acorrugation extending throughout its width, the clip having on each side of the springtwo faces having corrugated portions of corresponding'shape.
  • FIG. 1 is a longitudinal sectional view of a first embodiment of'a leaf spring according to the invention
  • FIG. 2 is a sectional view taken along line 2-2 of FIG. 1
  • FIGS. 3 and 5 are views similar to FIG. 2 of modifications, and
  • FIGS. 4 and 6 are sectional views taken along lines 4-4 and 66 of FIGS. 3 and 5.
  • FIGS. 1 and 2 show a spring R, comprising respec-' tively a single leaf 1 which has at its ends fixing eyes 2 and is integral in its centre portion with a fastening clip 3.
  • the leaf 1 has in the centre portion a corrugation la whose concavity is upwardly facing in the presently described embodiment, that is, it has the same orientation as the whole of the spring.
  • the clip 3 is composed of two parts 4 and 5 having a U-shaped section (FIG. 2), these two parts 4 and 5 having in the web portion thereof 4a, 5a, a corrugation corresponding to the corrugation la of the leaf and being provided in their flanges 4b, 5b, with apertures'4c, 50, for the passage of suitable fixing means.
  • the illustrated spring R has two leaves ll, 12, which are corrugated in their centre part and the fastening clip 13 is constructed in a somewhat different way.
  • This clip 13 is inone piece anddefines two corrugated strips 13a, 13b, which are disposed on each sideof the leaves and flanges 15a, 15b, which extend in a direction perpendicular to the leaves and are provided with openings 16 for the passageof fixing means.
  • the spring R shown-in FIGS. Sand 6 also has two" leaves 21,22, which are corrugated in their centre part andthe fastening clip 23 is soconstructed as-to permita different fixing method, two fixing tabs 24a, 24b extending fromthe upper strip of the clip in a direction
  • two fixing tabs 24a, 24b extending fromthe upper strip of the clip in a direction
  • the essential feature of the invention in all these embodiments resides-in the. fact that the centering of the leaveswith respect'to each other and with respect to the clip is achieved by forming in the leaves and in the adjacent strips of the clip corrugations which extend throughout the width of the leaves and therefore do not constitute a region of reduced section which would weakenthe spring.
  • the utilization of such centering means enables relatively short clips to be employed so that maximum resiliency of the spring is achieved.
  • a leaf spring structure comprising at least one leaf, a corrugation extending throughout the width of the leaf in 'a centre part the latter thelatter and a detachable fastening clip disposed in a centre part of the spring, said clip comprising two flanges which extend each in one side of said spring in a direction perpendicular to the plane of the leaf, two bearing surfaces extending from one flange to the other and each adjoining one opposite face of said spring, fixing tabs fast to said flanges, means defining apertures in these tabs for the passage of fixing means and corrugations in each of said bearing surfaces, said corrugations having a shape corresponding to the corrugation of the leaf.
  • a leaf spring structure as claimed in claim 1, wherein the clip comprises two members one inside the other, each member having twofianges and a web portion interconnecting the flanges and defining a U- shaped cross section, bearing surfaces on said two web portion adjoining opposite faces of the spring and being corrugated, the flanges of outer member extending beyond the inside member and forming two first fixing tabs and the flange of inside member forming two second fixing tabs parallel to the first, one on each side of the spring, and means defining apertures in said tabs for the passage of fixing means.
