Title:
BRAKE BOOSTER AND METHOD FOR PRODUCING A BRAKE BOOSTER
Document Type and Number:
WIPO Patent Application WO/2019/137657
Kind Code:
A1
Abstract:
The invention relates to a brake booster for a brake system of a vehicle having a first input piston component (10) which can be moved from its starting position by an input travel in a braking direction (12), and a valve body (18) which can be moved out of its starting position by a booster travel in the braking direction (12), and there is a differential travel of greater than zero at least temporarily between the booster travel and the input travel, wherein the brake booster has a second input piston component (26) which is pressed by means of a compression spring (28) away from the first input piston component (10) in the braking direction (12), and a locking mechanism (34) is configured in such a way that, as long as the differential travel between the booster travel and the input travel is smaller than a predefined first limit differential travel (Δx1), the second input piston component (26) can be moved together with the valve body (18) away from the first input piston component (10) by means of the compression spring (28), whereas, as soon as the differential travel exceeds the first limit differential travel (Δx1), the second input piston component (26) is locked on the first input piston component (10).
