Abstract
Official abstract text for this publication.
An electro-mechanical brake assembly comprising a brake disk stack having a center axis; and a plurality electro-mechanical actuators for applying braking pressure to the brake disk stack. The actuators are circumferentially arranged around the center axis, and each actuator includes a housing, a linearly movable ram, a screw for linearly moving the ram, a nut mounted for rotation in the housing and operatively engaged with the screw such that rotation of the nut effects linear movement of the screw for urging the ram into forceful engagement with the brake disk stack, an electric motor for rotating the nut, and an anti-rotation device for preventing rotation of the screw relative to the housing when the nut is rotated to effect linear movement of the screw. The foregoing arrangement provides for greater stroke than prior art actuators without sacrificing durability and performance.
First claim
Opening claim text (preview).
What is claimed is: 1. An electro-mechanical brake assembly, comprising: a brake head; a brake disk stack adjacent the brake head and having a center axis; and an electro-mechanical actuator mounted to the brake head for applying braking pressure to the brake disk stack, the actuator being radially offset from the center axis; the actuator including: a housing removably mounted to the brake head such that the housing can be removed from the brake head without removal of the…
