Abstract: A speaker can have a main body with a generally spheroidal shape, which can be supported standing on its end. The speaker can include a subwoofer that faces forward. A plurality of mid-range drivers can be distributed around the sub-woofer, facing generally forward and radially outward. A plurality of tweeters can be distributed around the sub-woofer, facing generally forward and generally outward. The outer housing portion of the speaker can be covered with a fabric material. A user interface ring 162 can be touch sensitive to receive input, and can have a plurality of lights that can be illuminated separately to convey information to the user.

Abstract: For fastening an mounting part to a hydraulic block of a hydraulic power unit of a hydraulic power vehicle braking system, holes are configured in a fastening flange of the mounting part with collars, which are clampingly inserted in mounting holes of the hydraulic block. A perforated disk is situated on the fastening flange as a fastening part and is fastened by screws screwed into the mounting holes of the hydraulic block.

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 stroke of a piston of a pedal travel simulator is limited via a spring ring that is inserted into a circumferential groove in a cylinder of the pedal travel simulator. The spring ring relieves the load on a cover of the pedal travel simulator that closes the cylinder of the pedal travel simulator.

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.

Abstract: A method for fixing a plurality of workpieces via a hollow rivet element with an open setting end and a closed closing end. The method includes passing the rivet element through mutually aligned openings of the workpieces. The method also includes introducing a fluid, in particular air, under high pressure from the setting end of the rivet element in a hollow space of the rivet element. The method also includes plastically deforming and setting of the rivet element by the fluid at the closed closing end of the rivet element.

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 method is provided for joining a plurality of workpiece parts, in particular body parts, in which: a) the workpiece parts are inserted into a joining tool, b) the workpiece parts in the joining tool are monitored for damages, c) the workpiece parts are joined by the joining tool, and d) the joined workpiece is monitored for damages in the joining tool.

Abstract: A connection arrangement is provided between a fiber-plastic composite profiled part and a vehicle body frame part. An intermediate piece is connected to the vehicle body frame part. The intermediate piece has a connection portion which is plug-connected and adhesively bonded to an end of the fiber-plastic composite profiled part. The end of the fiber-plastic composite profiled part is plugged onto the connection portion of the intermediate piece and is adhesively bonded on the inner surface to the connection portion.

Abstract: A method and device are provided for directly screwing together at least two components using a self-drilling and tapping screw which has a head and a shank formed onto the head with a self-tapping thread section and a hole-drilling section for flow drilling. The components are held pressed against one another by a holding down clamp while the screw is screwed in. The holding down force, with which the holding down clamp presses the components against one another while the screw is screwed in, is varied.
