Abstract: A method for manufacturing a hydraulic housing for a braking system of a motor vehicle. A cylindrical or hollow-cylindrical first housing part and a second housing part of the hydraulic housing are integrally joined using friction welding. The method includes: a) attaching the first housing part to the second housing part, an end face of the first housing part being attached to the second housing part so that a shared contact area is created, b) plasticizing the two housing parts in the contact area and/or in a joint area adjoining the contact area by friction-based heat introduction, and c) compressing at least one housing part and/or pressing a friction welding tool against the housing parts so that material forming and/or material shearing is effectuated in the plasticized area of the two housing parts and both housing parts form an integral joint in the contact area and/or in the joint area.

Abstract: A fastening system for fastening an annular body, in particular a covering cap, end shield, or the like. The fasting system includes an annularly extending side wall having an outer side and an inner side and comprising a collar which projects radially from the outer side, to an element, in particular a housing, hydraulic block or the like, which includes a receiving region for the collar. For fastening the annular body to the element, the element is or will be plastically deformed in such a way that the material of the element is or will be displaced to engage behind the collar. The element includes an annular recess having a caulkable lateral outer wall and having a retaining contour which is radially spaced apart from the lateral outer wall. The retaining contour is configured to interact in a form-fitting manner with the collar.

Abstract: An axial force transmitter for an actuating device of a brake system. The axial force transmitter includes an elongate first component, and an elongate second component, wherein the first component has a sleeve portion, a first end portion of the second component axially protruding into the sleeve portion, and wherein the sleeve portion and the first end portion of the second component are connected to each other in an axially fixed manner. The sleeve portion and the first end portion of the second component are connected to each other in an axially fixed manner by pressure forming of the sleeve portion. A method of producing an axial force transmitter is also described.

Abstract: A pivot bearing of a ball screw of a power brake pressure generator for a hydraulic vehicle braking system is fastened at a hydraulic block with the aid of a sleeve that has an internal circumferential edge, which engages from above with the pivot bearing on a front face facing away from the hydraulic block. The sleeve has a flange that is caulked in an annular step in the hydraulic block.
