Abstract
A suspension consisting of an elastic leaf (17) made of a composite material, having in its plane of vertical symmetry a height which increases towards the end or ends supporting the wheels. The leaf is fixed to the chassis (21) at two points (22) which are symmetrical relative to the longitudinal axis of the vehicle. The leaf may be mounted longitudinally or transversely. The leaf may consist of fibers extending longitudinally, without being cut, from one end to the other, embedded in an appropriate binder.
Claims5
An automobile suspension comprising a vehicle chassis, a wheel support, a damper, an elastic leaf having two free ends made of a composite material, and mounting means for mounting said leaf to said chassis;
- said leaf being fixed by said mounting means spaced from one of said free ends to said vehicle chassis and supporting at said free end said wheel support and said damper, said elastic leaf comprising a first section having a width and a thickness approximately constant and said first section extending approximately in a horizontal plane under said chassis between mounting means, and a second section with a decreasing width and an increasing thickness, said second section extending from said mounting means to the free end, the plane of symmetry of the free end being approximately perpendicular to the horizontal plane;
- said first and second sections of the leaf having constant and equal cross-sectional areas.
