Aircraft landing gear having axle to brake plate integration
First Claim
Patent Images
1. In combination in a landing gear system, having a main shock absorber piston:
- a structure disposed between adjacent wheel brakes for joining a right hand brake stator (27) to a left hand brake stator (29), said structure assembled to a landing gear truck beam (16); and
,said structure having rotational freedom concentric with the relevant brake rotation, and being connected to a fixed structure comprising the main shock absorber piston by a single brake rod, thereby enabling the reaction of loads due to brake application for all positions of the landing gear system including landing gear extended through landing gear retracted, and including gear at static during aircraft roll out and ground maneuvering.

Abstract
An aircraft landing gear brake arrangement wherein a landing gear stub axle and brake pressure plate are integrated. Each of the integrated assemblies is attached to a support fitting which pivots on the truck axle thereby causing the torque links to be unaffected by steering operations.

2. In combination in a landing gear system:
-
a single compensating link for reacting loads due to brake application from two wheel and brake assemblies to a stationary structure; said compensating link maintaining parallelogram geometry with respect to wheel axles during all main gear steering cycles; and
,said compensating link moving in a plane normal to the axle center of rotation.
