ABSTRACT:
An improved axle clamp is provided, particularly for use with composite material leaf springs, to securely fix the position of the leaf spring relative to a wheel axle or other suspension system member. The axle clamp comprises a rigid clamp base, a resilient wedge insert, a rigid clamp plate, and a resilient cover pad. The clamp base provides a bottom wall and substantially parallel side walls extending from the bottom wall to form a channel adapted to receive the wedge insert. The inner surface of at least one side wall of the clamp base fairs from both ends into a channel-widening concavity, preferably at the longitudinal mid-point of the channel. The wedge insert has a bottom wall and substantially parallel side walls extending from the bottom wall and forming therewith an inner channel adapted to laterally jacket a leaf spring. The outer surface of the wedge insert substantially fills the clamp base channel and, so, provides a convexity adapted to register with the channel-widening concavity of the clamp base. The clamp plate attaches to the clamp base to clamp the leaf spring between them. The resilient cover pad lies between the clamp plate and the leaf spring. The cover pad and the wedge insert each provides a vertically raised support pad extending laterally across the channel at each end to contact and support the leaf spring. The resilient material is recessed between the support pads.
