Abstract: A brake pad of a vehicle brake, in particular of a disc brake of a commercial vehicle, includes a brake pad carrier having a support surface, a friction lining attached to the support surface, a recess extending into the support surface in an axial direction, and a wear indication device arranged at least partially inside the recess. The brake pad carrier includes a clamping member coupled to the wear indication device that rests against an inner wall of the recess. The clamping member is configured to apply a clamping force on the wear indication device in a radial direction. The wear indication device and the clamping member are inserted axially into the recess.

Abstract: A solenoid valve including a non-sliding plunger assembly. The solenoid valve disclosed herein generally includes a plunger assembly that is moveably suspended within an internal chamber of a housing of the solenoid valve away from any sliding contact with adjacent surfaces. The plunger assembly may not be in sliding contact with any of the adjacent surfaces, and thus a radial gap may be defined between the plunger assembly and all non-moving, non-flexing features and surfaces of the solenoid valve. The solenoid valve may include a flexural washer that is resiliently flexible and is configured to enable selective axial movement of the plunger assembly in response to energizing the solenoid coil. In various embodiments, the flexural washer is configured to moveably suspend the plunger assembly within the internal chamber away from any sliding contact with adjacent surfaces.

Abstract: A system and corresponding method to move a rod of build material in a three-dimensional (3D) printing system uses a pusher. The rod of build material has distal and proximal ends relative to an extrusion head. The distal and proximal ends having distal and proximal end surfaces, respectively. The pusher engages with the rod and applies an axial force to at least a portion of the distal end surface of the rod for at least a portion of a path the rod travels toward the extrusion head. The axial force actuates the rod of build material without alteration, such as by shaving, fracturing, or otherwise deforming the rod of build material.

Abstract: A pull-type friction clutch having an annular part that is axially clamped to a disk spring and is axially fixedly connectable to an actuation sleeve of an actuation system. The annular part has axially raised lugs on its face bearing against the disk spring, and the lugs engage in slots that are provided between the disk spring tongues where the tongues are appropriately widened, to provide a form locking connection in the peripheral direction. As a result of the peripherally fixed attachment of the annular part to the disk spring, wear caused by a relative twist between the annular part and the disk spring is prevented.

Abstract: A starting clutch, particularly for racing and sports vehicles, has clutch plates, of which at least one is non-rotatably coupled with a clutch cage of the starting clutch and at least one is non-rotatably coupled with a clutch hub of the starting clutch. A set of springs composed of at least two diaphragm-spring-type spring elements presses the clutch plates together when the starting clutch is closed and permits a torque transfer from the clutch cage to the clutch hub and vice-versa. Viewed from the clutch plates, the first or second spring element has at least a first elevation on its side facing the respective second or first spring element, which elevation presses against the respective second or first spring element when the starting clutch is closed.

Abstract: A diaphragm spring for a friction clutch includes a ring-like body area and a plurality of spring tongues arranged at the inner edge in a row in a circumferential direction and extending radially inward from the body area. Openings are formed between adjacent spring tongues, each opening having a radially outer base area, at least one of the openings being limited in the circumferential direction by a wall area having a curvature which increases as the wall proceeds from the base area.

Abstract: A force-exerting element for a friction clutch includes a ring-like body with an outer edge area and an inner edge area. Openings provided in the body include a first group of openings open toward the outer edge area and a second group of openings open toward the inner edge area. The radial extent of circumferentially adjacent openings of the first group of opening and of the second group of openings overlap each other in the radial direction at the ends facing way from their associated edge areas or extend along approximately the same radial area. A radial support arrangement is arranged on the body to provide at least certain areas of support in the radial direction against the effects of centrifugal force.

Abstract: A first clutch area produces a first torque-transmitting connection between a drive element and a first driven element, and a second clutch area produces a second torque-transmitting connection between the drive element and a second driven element. A common engaging/disengaging mechanism actuates the first clutch area and the second clutch area to produce and to nullify the first and second torque-transmitting connections.

Abstract: A clutch having narrow housing and including a disengagement unit for a clutch pressure plate with a device for applying an essentially radially directed force onto the pressure plate, and wherein the device is driven in a radial direction.

Abstract: A friction clutch wherein a pressure plate is movable axially of and rotates with a housing which is driven by the engine of a motor vehicle. The pressure plate cooperates with a coaxial engine-driven counter-pressure plate to bear upon the respective friction linings of a clutch disc when the clutch is engaged to drive the input shaft of a transmission in the power train of the vehicle. A diaphragm spring is tiltable relative to an annular seat at the inner side of the housing and urges the pressure plate against the adjacent friction linings when the clutch is engaged. An automatic wear compensating unit serves to move the diaphragm spring and the seat axially relative to and away from the inner side of the housing to thus compensate for wear upon the friction linings. The diaphragm spring has resilient prongs which bear, directly or indirectly, upon portions of the housing to urge the diaphragm spring against the seat and to thus bias the seat toward the inner side of the housing.

Abstract: A friction damping device (50) capable of generating friction torque for controlling the relative rotation of a first and a second flywheel mass of the twin mass flywheel (10), the friction damping device comprising a first (62) and a second (51) friction member operatively connected with one flywheel mass (12) via a common drive formation (cdf) which forms part of the second friction member. A third friction member (56) is sandwiched between the first and second friction members and is operatively connected with the other flywheel mass (11), and actuating means (61, 67) is operative to axially displace the first and second friction members relative to each other to modify the friction generated by the device upon rotation of the third friction member relative to the first or second friction members resulting from relative rotation of the flywheel masses.

Abstract: A clutch cover 25 is disposed opposite to a pressure surface 26a of a pressure plate 26 and is fixed to a flywheel. The pressure plate 26 has the pressure surface 26a facing a friction surface 15 of a clutch disk. An annular lever plate 28 is supported at its outer circumferential edge to a clutch cover 25 and is contacted at a radially intermediate portion to the pressure plate 26. The pressure plate 26 is biased to be disengaged from the friction surface 15 of the clutch disk. A release bearing 31 is in contact with an inner circumferential edge of the lever plate 28 on the transmission side. A hydraulic cylinder 32 serves to move the release bearing 31 in the axial direction.
