Disc brake caliper body and a disc brake caliper comprising such a body

摘要

A body for a disc brake caliper has a mounting side limb and a non-mounting side limb, each limb housing at least one hydraulic brake cylinder. The body has a peripheral stiffening band that extends about an outer lateral surface of at least one of the limbs. In a preferred embodiment, a peripheral stiffening band extends about an outer lateral surface of each of the limbs. The stiffening band or bands provide stiffness in the body under dynamic braking conditions with a minimum of material. A method of designing and manufacturing a body for a disc brake caliper involves analyzing the stiffness of the body under dynamic rather than static braking conditions and producing a caliper body with a desired level of stiffness under dynamic conditions while reducing the amount of material used to a minimum.

主权项

1. A disc brake caliper body, the disc brake caliper body having opposite longitudinal ends, a mounting side and a non-mounting side, and comprising a mounting side limb and a non-mounting side limb, said limbs being rigidly interconnected at either longitudinal end of the caliper body by a respective bridging member, the disc brake caliper body defining a pair of longitudinally spaced mounting holes located in the mounting side of the body, each limb having an outer lateral surface and at least two hydraulic brake cylinders defined therein, said brake cylinders suitable for receiving corresponding hydraulic brake pistons, and each limb being profiled to define a housing portion about each cylinder, in which the body has two peripheral stiffening bands, each peripheral stiffening band extending about an outer lateral surface of a respective one of the limbs and interconnecting outer lateral end regions of the cylinder housing portions of said respective limb, at least one of said peripheral stiffening bands having a portion extending about a longitudinal And of its respective limb and connecting with a respective bridging member at that longitudinal end of the caliper body, at least one opening, separate from said mounting holes, being defined in a region of the caliper body located between said extending portion of said at least one peripheral stiffening band, said longitudinal end of said respective limb and said respective bridging member.
