VACUUM BRAKE BOOSTER HAVING AN ASSEMBLY-FRIENDLY CHAMBER ARRANGEMENT AND METHOD FOR ASSEMBLING A VACUUM BRAKE BOOSTER

摘要

The invention relates to a vacuum brake booster (10) having a chamber arrangement (12) for producing a servo force that supports a brake actuating force, wherein the chamber arrangement (12) comprises a housing (14), in which a working chamber (22) is separated from a vacuum chamber (24) by a movable wall (26), wherein the housing (14) has a first housing shell (16) and a second housing shell (18), which are or can be connected to each other in a sealing manner in a connection area (20), wherein a flexible section (30) of the movable wall (26) is arranged in a sealing manner in the connection area (20), and wherein the housing shells (16, 18) of the housing (14) are penetrated by at least two fastening bolts (32) in order to fasten the vacuum brake booster (10) to a vehicle chassis. For easier assembly, at least one of the fastening bolts (32) is provided with an engagement formation (46, 50), with which one of the housing shells (16) can be brought into engagement during the assembly, and thus said housing shell can be permanently locked in a predetermined position relative to the other housing shell (18).
