The first spring limb (5) forms the resilient section (8). The bending joint section (11) contains the second spring limb (6). The second spring limb (6) is shorter than the first spring limb (5) and oriented approximately perpendicularly to the first spring limb (5). The leaf spring (1) is integrally produced from unidirectional prepregs having a duroplastic or thermoplastic matrix by means of a pressing method.

A method for annealing a strip of steel having a variable thickness in its length direction with at least thicker and thinner sections, wherein the strip has been cold rolled to form the thicker and thinner sections, one thicker and one thinner section having a length of at most a few meter. The annealing is performed by continuous annealing.

Abrégé

A wheel suspension is described with a wheel-guiding McPherson strut unit which has a helical compression support spring, a shock absorber which is connected on one end to the body and on the other end to the wheel, and a suspension arm, the helical compression spring being made such that the helical compression spring at least partially compensates for transverse forces which occur on the shock absorber without the action of the helical compression spring. To enable the weight of the helical compression spring to be reduced, the helical compression spring is constructed and arranged so that the stress in the spring is at least approximately, preferably exactly, the same on the side of the spring center line or line of action of the spring force facing the wheel as on the side facing away from the wheel. This makes it possible to reduce the weight throughout by roughly 10%.
