Abstract: The invention relates to spring elements and bearings which contain these spring elements, the spring stiffness of the bearings and spring elements being individually adjustable by deformable elastomer bodies or elastomer layers by prestressing. The deformation of the elastomer layers and hence of the spring elements is achieved by an appropriately designed hydraulic device. The leak-tightness of the spring elements and bearing elements according to the invention is achieved through special hydraulically prestressed sealing elements, use of a pressure membrane and special structural features of the elastomer elements.

Abstract: An independent wheel suspension with a rotating steering knuckle which supports itself on a spring carrier is connected with the vehicle frame via a damper. The steering knuckle is connected with the spring carrier via a kingpin, and the wheel suspension has upper and lower transverse links which are positioned at the upper or lower ends of the kingpin. The steering knuckle and the transverse links are pivotally positioned relative to the kingpin and the spring carrier is connected with the kingpin in a rotationally fixed manner. The kingpin connects the spring carrier, the steering knuckle, and the upper end lower transverse links and is a two-piece part which comprises upper and lower parts. Axially, radially and rotationally fixing the upper and the lower parts and the spring carrier is achieved by a combination of the upper and the lower parts with the spring carrier.

Abstract: An arrangement for planetary gearsets comprises at least simple radially inner and radially outer planetary gearsets each comprising a sun gear, a ring gear and a carrier that carries planetary gears.

Abstract: The invention concerns an automated motor vehicle shift transmission (1) with an input shaft, an output shaft and several selectively engaged gears, the input shaft (W1) being connected to a drive motor (M) via an engine clutch (K) that can be engaged and disengaged. To avoid an interruption of the traction force during a shift process, a controllable friction clutch is provided as a change-under-load clutch (K5) to connect the input shaft (W1) directly to the output shaft (W3, W4) when necessary. The invention also concerns a method for controlling the gearshifts of an automated motor vehicle shift transmission comprising an input shaft, an output shaft and several selectively engaged gears, and in which the input shaft is connected to a drive motor via an engine clutch that can be engaged or disengaged, such that in a shift process between a loaded gear that is engaged and a target gear to be engaged, the engine clutch remains closed during the gear change.

Abstract: A device for connecting, in a rotationally fixed manner, a shaft to at least one component which is rotationally supported on the shaft, such as a gear wheel of a gear in a transmission. The device includes an actuating element that is rotationally fixed, but axially slides on the shaft, such that when the element is actuated by an actor, the element actively, frictionally communicates with the component to at least approximately equalize a rotational speed difference, between the component and the shaft. The actuating element can be actuated by the actor with a force to frictionally connect the component to the shaft in a rotationally fixed manner. The device further includes a holding device, which retains the actuating element in a shift condition essentially equivalent to the rotationally fixed condition of the component without further actuation of the actor.

Abstract: A spinal prosthesis has a prosthetic vertebral body in the form of a hollow cylinder (1) with perforated wall and attached prosthetic intervertebral discs formed by springs (7,8) molded into silicone-rubber beads (9,10). Anchoring of the cylinder (1) to the damaged vertebra (II) is by means of entrapment of an elongate lug (12) of the cylinder 1 within a slot (16) of a plate (11) retained by screws (12) within a recess (13) of the damaged vertebra (II). The springs (7,8) of the resilient beads (9,10) are attached to the natural vertebrae (I,III) superior and inferior to the damaged vertebra (II) by fixing plates (3,4) which have flanges (20,21) that are held by screws (22) to those vertebrae (I,III). Where adjoining vertebrae are damaged, two or more prosthetic cylinders (1) for anchoring to the individual vertebra are used with interconnecting resilient beads (9;10).

Abstract: A clutch system for producing and interrupting a force flow between the engine and transmission of a motor vehicle, with a clutch, which is disengaged unless actuated, and one or more valves, which regulate the flow of pressure medium and which are electrically actuated by a control and regulation unit. If there is electrical failure while driving and when a gear is engaged or when the vehicle is stationary, the engine is running and a transmission gear is engaged, unintended clutch engagement is prevented. The valves are designed such that if there is a failure of the voltage supply and consequently also of the actuation of the valves by the electronic control and regulation system, the operating condition of the clutch existing at the time of failure, namely the disengaged or engaged operating condition, remains as it is.
