Abstract
The invention relates to a removable thrust rod in a brake-booster of the partial vacuum type. The thrust rod (24) is attached securely to a skirt-shaped component (42) which surrounds the reaction disk (30) and to a component (44). A detachable component (50) comprises clipping fingers (54) which interact with the periphery of the component (44) and an annular part (52) which is flattened onto the piston (18) of the booster by a return spring (34).
Claims3
A vacuum brake-booster comprising a casing separated into two chambers by a diaphragm, a piston attached securely to a central part of said diaphragm, a reaction disk, a thrust rod disposed in said casing, means for attaching securely said thrust rod and reaction disk to said piston, and resilient means applied to said piston, characterized in that the attachment means comprises plate-forming means attached securely to one end of the thrust rod, said plate-forming means comprising a ring-forming part surrounding the reaction disk and interacting with said piston and a portion applied against one face of said reaction disk and having a periphery, and fastening means having a part forming a bearing surface applied at a surface of said piston by said resilient means and a clipping part interacting with a peripheral portion of the plate-forming means so that said rod and plate-forming means can be detached from said piston by action on said clipping part.
