Title:
ACTUATING UNIT FOR A HYDRAULIC BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/158626
Kind Code:
A3
Abstract:
The invention relates to an actuating unit (1) for a hydraulic brake system, comprising an actuating pedal (11), at least one working piston (16) of a main brake cylinder (3), a booster piston (13) of a hydraulic brake booster guided in a booster housing (10) for actuating the working piston (16), a pedal connection element (30) for charging the booster piston (13) with an actuating force, an elastically deformable reaction disk (23), which on one side absorbs the actuating force and the boosting force of the hydraulic brake booster, and on the other side releases the sum of said forces to the working piston (16), an electrically controllable pressure supply device (2), the output pressure of which acts upon the booster piston (13). The actuating unit further comprises means (29, 129, 130) for detecting the differential path between the pedal connection element (30) and the booster piston (13), a sensor device (28, 128) for detecting the differential path, and an electronic control and regulating unit (18), which receives the signals delivered by the sensor device (28, 128) and uses said signals for controlling the pressure supply device (2). The means (29, 129, 130) comprise at least one extension arm (29, 129, 130), by way of which at least one path information for detecting the differential path is transported to a location near the sensor device (28, 128) that is radially and axially offset by the reaction disk (23).
