Title:
REACTION ARRANGEMENT FOR BRAKE BOOSTER
Document Type and Number:
WIPO Patent Application WO2006036342
Kind Code:
A3
Abstract:
A reaction arrangement (400) for a brake booster (10) having a control valve (100) selectively activated by a manual input force or an electromagnetic force to allow air to create a pressure differential with 5 vacuum and produce an output force that is transmitted through an output member (422) in effecting a brake application. The output member (422) encounters resistance during the brake application that is defined by a reaction force transmitted through a disc (224). A first shaft (550) engages the disc (224) and communicates the reaction force to balance the manual 10 input force while a smaller second shaft (404,404') engages the disc (224) and communicates the reaction force to balance the electronic force such that a resulting output force to effect a brake application is similar whether initiated by an operator (38) or an electronic control unit (40).
