Abstract
This invention is directed to an improved device for connecting an elastic suspension leaf arranged between a load and a carrier, particularly of a vehicle, to the walls or the like and to the chassis. The suspension leaf comprises a composite material having in its vertical plane of symmetry a thickness increasing from the chassis to the end support of the wheel, its cross-section remaining approximately constant. At least one device for connecting to the chassis includes a lower part which retains the leaf and which has a trapezoidal shape in projection in a horizontal plane and a U-shaped cross-section in a vertical plane, and a semi-cylindrical upper part possessing an axial bore which receives a shock-absorbing device for fastening the device to the assembly. The dimensions of the lower part ensure that the part fits onto the gradually varying shape portion of the leaf at the fastening points of the leaf. This device, inter alia, utilizes the progressively varying shape of the elastic leaf to provide an enhanced assembly.
