Abstract
The present invention provides a variable ratio brake pedal actuating assembly with an early increase of geometric ratio or force ratio and a subsequent decrease. The actuating assembly comprises a mount, an arm, an input portion and an input connector. The input connector is operatively connected to the arm such that the ratio varies as the arm moves. The ratio reaches a maximum peak prior to moving 30% of the fully stroked position. Also provided is an actuating assembly that uses a cam guide structure with a contoured cam surface and a link member. A configuration of the contoured cam surface, a guide slot, and the link member are such that the ratio varies as the arm is moved. Yet another aspect of the present invention is to provide a cam guided booster pin linkage assembly that provides a variable pedal ratio.
