Definitions

  • the present invention relates to improvements inv springs, particularly suspension springs for motor vehicles, whereby the n oscillations of these springs are autoiiiati U call damped.
  • .Tlie invention is essentially characterized by the combination of two superposed'leaves one of which is ⁇ connected at one end to the chassis, While the other leaf has its correo sponding end movable and guided by means of double shackles or of slides, so that the movement of yielding and recovery of this spring produce friction between these leaves by means of which the oscillations of this spring are rapidly damped.
  • the invention comprises all the modes of construction in which the above combination is found, which combination maybe either single or double or associated with other friction elements or with counter leaves serving to complete the spring.
  • Fig. 1 is a Side elevational view of one form of the improved supporting spring.
  • Fig. 2 is a top plan detail of the spring leaves with the securing means removed.
  • Fig. 3 is a fragmentary elevational detail of the arrangement shown inllig. 1
  • leaf springs Z and f arranged in superposed relation with each other, the spring Zhaving one end a pivoted to the forwardv end of the chassis while the opposite endl b is free to move i being pivoted to the outer end of a link jl in turn pivoted to a bracket suspended from the chassis.
  • the other leaf spring f has its opposite end pivoted to the pivot point of the link jl as at cZ while the other end'c is free to move relative to the leaf spring Z being pivoted at the outer end of a link j the inner end of which is pivoted at the fixed point of the support of the leaf spring Z.
  • the damping is thus constantly propor- 5 tional to the amplitude of the oscillations.
  • the new spring thus forms a powerful brake, which promptly and eectively clamps the oscillations.
  • the braking action due to the friction is increased as explained above by the initial curvature of the leaves and by the play of the shackles.
  • the new springs comprise no weak point -nor any break in cont-inuity over the whole of their length.
  • shock absorbers permit the shock absorbers to be dispensed with because they perform at the same time the function of springs and that of shock absorbers. Moreover, they prevent the movements of rolling and shimmy.
  • the entire spring is attached to the chassis by the fixed axes ca (Z of the two main leaveswithout any joint, thus eliminating the transverse reactions which produce rolling andV shiinmy, so that the vehicle holds the road more satisfactorily; besides, the double main leaf reinforces the'spring and constitutes a security element.
  • the springs maintain their ordinary appearance and the shock absorbers, their littings, their assemblage, their adjustmentand their inconveniences are eliminated.
  • a suspension spring comprising two leaves each of which is secured at one end to a fixed point while the other end is free and positioned adjacent the fixed end of the other leaf, one of said leaves being provided 45.1 with a slot, and a stationary spacing plate mounted in the slot allowing relative longitudinal movement of the two leaves.
  • a spring comprising two leaves one'of which has one end fixed while the opposite lend is mounted for movement while the other leaf has one end fixed near the movable end of the first leaf and its opposite end mounted for movement, said leaves being movable .securing means.
  • a suspension spring comprising two superposed leaves each having one end secured to the chassis and its opposite end free, the fixed end of the spring being remote from each other, securing means for the middle portions of the leaves, one of the leaves being provided with a slot, and a spacing plate mounted in the slot for allowing relative longitudinal movement of the two leaves and being fixed to the securing means.
  • a spring comprising two main leaves 'having reversely curved ends and movable relative to each other and in frictional vcontact with each other their entire length, securing means associated ⁇ with the middle portions of the leaves, one of the leaves being solid and the other being provided with a slot, a distance piece Amounted in. the slot,
  • a spring comprising two main leaves having reversely curved ends movable relative to-each other over the entirelength, and in friction with each other over their entire' extent, one leaf ⁇ being solid and the other 65- being provided with a slot, a'distance piece
