  • Patent number: 9217482
    Abstract: The invention relates to a leaf spring (1) for motor vehicles, which is made of a fiber-reinforced synthetic material and can absorb potentially occurring lateral forces and transfer them to a leaf spring receiving device, comprises a first end (2) and a second end (3), which can each be fixed in a leaf spring receiving device in a torsion-proof and non-displaceable manner, and a bending joint section (11), which can compensate for a change in length of a resilient section (8) of the leaf spring (1) during a load-induced deformation of the resilient section (8). The leaf spring (1) comprises a first spring limb (5) and a second spring limb (6) which are connected to each other via a transition section (7). In a non-loaded state, both the first spring limb (5) and the second spring limb (6) are approximately planar and disposed at an angle relative to each other. The first spring limb (5) forms the resilient section (8). The bending joint section (11) contains the second spring limb (6).

  • Patent number: 6805370
    Abstract: An independent rear suspension for a motor vehicle chassis includes a pair of independent rear corner modules. Each rear corner module includes a generally-longitudinally-extending leaf spring whose forward end is adapted to be pivotally mounted to the vehicle chassis at a first forward attachment point, and whose rearward end is nonrotationally-coupled to a knuckle, such that the leaf spring operates as a trailing arm to longitudinally position the knuckle relative to the chassis. A shackle adapted to be pivotally mounted on the chassis at a second forward attachment point includes an eye that encompasses a portion of the spring intermediate the first and second end of the spring. The shackle permits a predetermined, nonzero range of relative longitudinal, transverse, and torsional movement of the intermediate portion of the leaf spring while otherwise transferring vertical loads from the intermediate portion of the spring to the chassis.

  • Patent number: 4927124
    Abstract: Assembly comprising a spring in the form of a zig-zag strip of fibre reinforced plastics material with limbs (10-16) connected by reflex portions (17,22), wherein end limbs (10,16) of the spring are mounted at an attitude they would adopt when loaded if they were pin-jointed so as to be free to move as the spring is loaded so that over-stressing of the reflex portions (18,21) of the spring is thereby avoided when the spring is loaded. In modifications of the invention, a spring end limb (39) may be progressively engaged by a surface (42) of a mounting to be supported at a range of attitudes corresponding to a range of spring loads; or a spring mounting may be associated with pivotable members so that end limbs of the spring move arcuately therewith and change their relative attitude as if they were pin-jointed.
