BRAKE BOOSTER ASSEMBLY

摘要

A brake booster assembly is provided. The assembly includes a rack including a plurality of rack teeth extending therefrom and moveable and extending along a first axis. A sensor is coupled with the rack for sensing force and axial displacement of the rack and outputting a signal proportional to the sensed force and the sensed displacement. A planetary gear subassembly is disposed about a second axis transverse to the first axis and is coupled with the rack for moving the rack along the first axis in response to rotation of the planetary gear subassembly about the second axis. A pair of motors are coupled to the planetary gear subassembly for rotating the planetary gear subassembly and moving the rack along the first axis. A controller is electrically connected to the sensor and to the motors for controlling rotation of the planetary gear subassembly in response to the signal from the sensor.

1. A brake booster assembly comprising:
a rack moveable along a first axis, at least one sensor coupled with said rack for sensing force and axial displacement of said rack and outputting a signal proportional to the sensed force and the sensed displacement, a planetary gear subassembly disposed about a second axis transverse to said first axis and coupled with said rack for moving said rack along said first axis in response to rotation of said planetary gear subassembly about said second axis, a first motor coupled to said planetary gear subassembly for rotating said planetary gear subassembly about said second axis to move said rack along said first axis, a second motor coupled to said planetary gear subassembly for rotating said planetary gear subassembly about said second axis to move said rack along said first axis, and a controller electrically connected to said at least one sensor and to said first motor and said second motor for controlling rotation of said planetary gear subassembly and axial movement of said rack in response to the signal from said at least one sensor.
