An axle suspension for a motor vehicle includes a longitudinal leaf spring made of fiber composite and having ends coupled to the motor vehicle. The leaf spring has an attachment zone and two arms which extend from the attachment zone to the ends of the leaf spring to define a trailing arm and a leading arm in a travel direction of the motor vehicle, with the trailing arm having a cross sectional dimension which is greater than a cross sectional dimension of the leading arm. A clamping device couples an axle component to the leaf spring substantially in midsection of the leaf spring and is arranged offset in longitudinal direction from the midsection of the leaf spring.

Axle suspension with longitudinal leaf spring for a motor vehicle

A leaf spring for a motor vehicle is made from a fiber composite component including individual fibers in form of at least two textile layers stacked on top of each other and a matrix made of a duroplastic or thermoplastic resin surrounding the fibers. The resin is hardened in a mold tool by applying pressure and heat. The stacked textile layers are formed inside a mold tool and fixed by a dry binder applied to at least one of the textile layers to form a dry preform. A fiber composite blank is stamped from the preform and subsequently infiltrated with the resin in a RTM cavity and hardened. The binder applied in dry form may only be arranged in certain areas of the textile layers.
