ABSTRACT:
A braking system for a vehicle. The braking system provides continuous tactile feed back through the brake pedal to the operator of the vehicle that conforms to the degree to which the vehicle brakes are being applied so that the tactile feed-back to the operator conforms to the visual and kinesthetic input received by the operator. The braking system has a brake pedal that is mounted to be depressed in response to a force applied thereto by the vehicle operator. The braking system incorporates both a mechanical brake actuating mechanism and a hydraulic brake actuating mechanism. The braking system provides for selective actuation of the mechanical brake actuating mechanism sequentially in advance of the hydraulic brake actuating mechanism when the brake pedal is depressed. A linkage assembly is incorporated in the mechanical brake actuating mechanism. The linkage assembly provides tactile feed-back to the brake pedal throughout the range of operation of said braking system. Subsequent to the mechanical actuation of the braking system, continued depression of the brake pedal actuates the hydraulic brake actuating mechanism. This sequencing is provided by a brake actuating system embodying the concepts of the present invention and is responsible for the reliable tactile feed-back reflected in the brake pedal.
