Patent ID: 7793765

Claim:
A multi-disc brake comprising: a knuckle for supporting a wheel; a hub mounted for rotation on said knuckle about a rotation axis; an inboard disc mounted for rotation with said hub and for sliding movement on said hub along said rotation axis and having a first inboard engaging surface and a first outboard engaging surface; an outboard disc mounted for rotation with said hub and for sliding movement on said hub along said rotation axis and having a second inboard engaging surface and a second outboard engaging surface; an inboard brake pad assembly disposed adjacent to said first inboard engaging surface of said inboard disc for sliding movement along said rotation axis relative to said hub; an outboard brake pad assembly disposed adjacent to said second outboard engaging surface of said outboard disc; a center brake pad assembly disposed between said first outboard engaging surface of said inboard disc and said second inboard engaging surface of said outboard disc for sliding movement along said rotation axis relative to said hub; a brake fist having a bridge portion extending outboard from said knuckle around said discs and said brake pad assemblies to an outboard wall for supporting said outboard brake pad assembly against outboard movement along said rotation axis; an actuator for urging said discs and said brake pad assemblies together against said outboard wall to slow rotation of said hub; a first bolt extending along a first bolt axis and a second bolt extending along a second bolt axis spaced from said first bolt axis across said outboard wall for connecting said brake fist to said knuckle; and a reinforcing rib extending along a longitudinal axis from said first bolt axis to said second bolt axis, said reinforcing rib extending outwardly from and across said outboard wall in a plane perpendicular to said inboard and said outboard discs, wherein said first bolt axis extends through a first center point of said reinforcing rib and said second bolt axis extends through a second center point of said reinforcing rib such that said reinforcing rib limits deflection of said outboard wall, and wherein said reinforcing rib is formed directly on and is connected to said outboard wall along said longitudinal axis continuously in one connection from said first bolt axis to said second bolt axis.
