CALIPER MOUNTING ARRANGEMENT
First Claim
Patent Images
1. A brake caliper assembly, comprising:
- a caliper body for supporting a brake pad having a braking surface that selectively engages a brake rotor;
a torque plate connected to the caliper body, the torque plate having a mounting member for connection to a vehicle support;
a fastener that fastens the caliper body to the torque plate, andwherein one of the caliper body and the torque plate includes at least two protrusions extending outwardly therefrom and the other of the caliper body and the torque plate includes at least two cavities that are shaped to correspond to the protrusions and mate therewith so that forces generated during braking are transferred between the caliper body and the torque plate via the protrusion and cavity and said fastener is isolated from shear forces generated by said braking, andwherein each of said protrusions has two opposing surfaces that are substantially parallel to an axis of rotation of said brake rotor and two opposing surfaces that are substantially orthogonal to said axis of rotation, and each of said cavities is complementary in shape to its respective protrusion such that each of said opposing surfaces of said protrusion abuts a surface of its respective cavity to isolate said fastener from said shear forces.

Abstract
A brake caliper assembly includes a caliper body connected to a torque plate via a mating protrusion and cavity that transfer torque through facing abutment surfaces to reduce twisting of the caliper. The mating protrusion and cavity provide a stiff connection and also allow use of a smaller, lighter connecting bolt. This arrangement eases removal and reinstallation of the caliper.

28. A caliper assembly for use with a disc brake system for a vehicle, comprising:
-
a caliper body having a bottom surface and a pair of side walls defining a space therebetween for accepting a portion of a brake rotor; a torque plate having a top surface that connects with the bottom surface of the caliper body and having a mounting flange for mounting the caliper assembly to a fixed mounting member; and
,a fastener fixing the caliper body to the torque plate; means for isolating said fastener from shear forces caused by relative flexing between the caliper body and torque plate during a braking operation including at least two protruding members extending from one of the bottom surface and the top surface and at least two corresponding depressed areas located in the other of the bottom surface and the top surface that mate with the protruding members to form a connection between the caliper body and torque plate through which shear forces are transferred during braking, and a corrosion resistant clip disposed between the protruding members and the depressed areas, wherein each of said protrusions has two opposing surfaces that are substantially parallel to an axis of rotation of said brake rotor and two opposing surfaces that are substantially orthogonal to said axis of rotation, and each of said cavities is complementary in shape to its respective protrusion such that each of said opposing surfaces of said protrusion abuts a surface of its respective cavity to isolate said fastener from said shear forces. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
