Abstract: A disk brake for a vehicle having a bracket which is fixed with respect to the vehicle and on which brake linings and at least one brake caliper are mounted so as to be movable in an axial direction is disclosed. The bracket and the brake caliper engage around at least one brake disk, and the brake caliper includes a housing limb with at least one actuating device, a further housing limb with at least one housing finger, and a housing bridge. A spring arrangement which generates an elastic preload between the brake caliper and the bracket is provided in such a way that the preload is aligned substantially perpendicular to a movement direction of the brake caliper. The spring arrangement comprises a spring element and a protective panel.

Abstract: An oil filter assembly (10) has a receiving chamber (18) that can be closed by a cover element (14) and a spring-loaded supporting tube (22) that is fixed in the receiving chamber and is designed to receive a filter element (20) that can be radially traversed by oil. The supporting tube (22) is axially displaceable between an operating position and a drain position in such a way that, in the operating position when the receiving chamber is closed by the cover element (14), the tube closes a drain opening (42). When the receiving chamber is open in the drain position, the tube releases the drain opening. The supporting tube is mounted to rotate through a rotational angle that is limited by two rotational stops (41, 43) in the housing and the cover element has follower sections (66, 68, 70) that co-operate with the supporting tube and/or filter element to rotate the supporting tube through the rotational angle when the cover element is screwed on and/or unscrewed.

Abstract: A disk brake having a brake disk, a brake caliper including a bracket, a caliper housing and a brake lining. The bracket and the caliper housing engage axially around the brake disk, with the caliper housing and the brake lining movable in an axial direction. The caliper housing has outer housing limb comprising two housing fingers which run substantially in a radial direction and which span a limb window situated between them and which is open in the direction of the rotational axis, with the housing fingers having one end section facing the rotational axis. A protective screen covers end sections of the housing fingers and conceals a section of the limb window that faces the rotational axis, with an outer dimension of the protective screen in a circumferential direction such that a transition between the protective screen and the housing fingers is substantially stepless in an axial projection.

Abstract: An oil filter assembly (10) comprises a housing (12) that has a holding space for a filter element (20), which can be placed inside the housing and through which oil can radially flow, an oil inlet, an oil outlet, and a supporting tube (22), which supports the filter element. A guide (62) for a compensating body of the outlet valve is provided on a part that is separate from the housing (12). The compensating body (58) serves to compensate for axial tolerances of the housing and/or of the filter element.

Abstract: A disc brake for a motor vehicle having at least two axially stationary friction rings being connected to a rotatable hub. The disc brake comprises several brake pads cooperating with the associated friction rings during a braking operation. A favorable structural overall design of the disc brake is achieved by a brake caliper straddling all friction rings and the associated brake pads and including a first actuating device in a brake caliper portion that extends axially beside the friction rings, and a second actuating device that is arranged between two friction rings and acting axially on both sides. Said actuating device acts on the brake pads arranged between two friction rings and is arranged so as to be displaceable relative to the brake caliper.
