Electric brake system with flexible force transfer member

摘要

A brake assembly and system (202) characterized by the use of a flexible force transfer member (230) to enable an electric motor (220) to be mounted remotely from other brake components and preferably at a location shielded from the elements and/or more easily accessible for maintenance and repair. By mounting the electric motor (220) in a less confining area, and using a force distribution device (350) to distribute force to a plurality of rams (342,344), one larger motor (220) may be used to drive multiple disk engagement members rather than several smaller motors mounted on the brake assembly. Since larger motors are typically more efficient than smaller motors, using one larger motor increases the overall efficiency of the brake.

1. An aircraft brake system comprising
an aircraft brake disk mounted proximate to a first portion of a strut; a master ram module positioned to apply braking force to the aircraft brake disk; a second ram module positioned to apply braking force to the aircraft brake disk; an electric motor for actuating the master ram module and the second ram module mounted directly on a landing gear well proximate to a second portion of the strut, the first portion of the strut opposite the second portion of the strut when the strut is in a deployed position; a first cable connecting the electric motor to a gearbox for transferring an input force from the electric motor to the gearbox, wherein the gearbox is mounted to the master ram module, the gearbox comprising a plurality of gears to reduce input force, wherein the gearbox distributes force equally between the master ram module and the second ram module, wherein the gearbox transfers a first force from the gearbox directly to the master ram module; and a second cable for transferring a second force from the gearbox to the second ram module, the second cable connecting the gearbox to the second ram module.
