Abstract
A wheel suspension with a transverse leaf spring (1a–1c) which is articulated at both ends on wheel carriers. The transverse leaf spring shaped symmetrically to the vehicle longitudinal axis (L) has a curved profile with a middle region (1a) offset parallel to the wheel axis. The transverse leaf spring is supported on the vehicle body by means of two transverse leaf spring bearings (2) with high lateral rigidity. The curved profile of the transverse leaf spring with four arcs (1d, 1e) allows for a bending of the middle region (1a) to take place essentially without a change in the tread width.

A motor vehicle having a wheel suspension including a transverse leaf spring, wherein the transverse leaf spring comprises:
- a middle region extending generally transversely to the motor vehicle;
- a torsional portion extending generally parallel with a longitudinal axis of the motor vehicle;
- a first arc connecting a first end of the middle region with a first end of the torsional portion;
- an end portion extending generally transversely to the motor vehicle and having a wheel-side end adapted for connection to at least one wheel carrier;
- a transverse leaf spring bearing connected to the end portion and adapted for connection to a body of the vehicle;
- and
- a second arc connecting a second end of the torsional portion with a second end of the end portion.
