US 2006/0213729 A1 · Gain stabilizing self-energized brake mechanism

Abstract

A self-energized disk brake assembly includes gain stabilization features for controlling the multiplication of applied force against a rotatable brake member. The brake assembly includes a first brake pad supported about a first pivot and a second brake pad supported about a second pivot. An actuator applies a force to drive the brake pads into the rotatable brake member. Frictional force between the brake pads and the rotatable brake member pulls the brake pads into further engagement generating an increase in braking force from self-energization. A position of the first and second pivots is adjustable to control the amount of braking force generated from self-energization.

Dependent claims

A self-energizing brake assembly comprising:

a rotatable brake member that is rotatable within a plane of rotation;
a first arm pivotally attached about a first pivot axis and including friction material for engaging said rotatable brake member;
a second arm pivotally attached about a second pivot axis including friction material for engaging said rotatable brake member;
a hinge member attached to said first arm on an end opposite said first pivot axis, and to said second arm on an end opposite from said second pivot axis;
and
an adjustable member for controlling a gain in braking force from self-energization by adjusting a distance between said first pivot axis and said second pivot axis, wherein said adjustable member comprises a first threaded member threadingly engaged to said first arm and said second arm at said first pivot axis and said second pivot axis.
