  • DEVICE FOR VARIABLY ADJUSTING THE CONTROL TIMES OF GAS EXCHANGE VALVES OF AN INTERNAL COMBUSTION ENGINE
    Publication number: 20110162603
    Abstract: A device for variably adjusting the control times of gas exchange valves of an internal combustion engine. The device has a driving element, an output element, at least one pressure chamber, at least one mechanism limiting the angle of rotation, and a pressure accumulator. A phase angle between the output and driving element is changed by delivering or discharging pressure medium to or from the pressure chambers. The mechanism limiting the angle of rotation has a receiving member and an engaging element to which a force is applied towards the receiving member (45). When locked, where the engaging element engages into the receiving member, the mechanism limiting the angle of rotation limits the phase angle of the output element relative to the driving element at least to an angular spread. The mechanism limiting the angle of rotation can be unlocked by applying pressure medium to the receiving member.

  • STEERING KNUCKLE WITH PRE-SEALING
    Publication number: 20110148182
    Abstract: A steering knuckle, which is provided for receiving an outer ring of a wheel bearing, and a wheel bearing arrangement with such a steering knuckle. The sealing arrangements of the wheel bearing has a pre-seal, which is designed as a labyrinth seal to provide sealing for an appropriate gap geometry. To this end, the steering knuckle has a collecting channel, which captures liquids and dirt particles and discharges them at the periphery. The hearing seal can be changed by this measure, so that savings are possible with a minimum of sealing action of the conventional sealing arrangement and with greatly reduced friction torque. Overall, the sealing action, which is now achieved by the bearing seal and the pre-seal together, is increased or remains at least at the same level while manufacturing costs are reduced.

  • CENTRIFUGAL RING WITH COLLECTING CHANNEL
    Publication number: 20110150380
    Abstract: A seal arrangement with a centrifugal ring for a sealing between a rotatable bearing part and a static bearing part. The centrifugal ring has a first end piece, which forms both an outer circumference of the centrifugal ring and a cutoff edge located on a disk-shaped outer face. The seal arrangement reduces the coefficient of friction without having to accept any loss of sealing effect, but in which the seal arrangement nevertheless remains cost-effective to manufacture. For this purpose, the centrifugal ring has a second end piece. The end pieces together form a first collecting channel in the vicinity of the cutoff edge and the end pieces each form an annular seal gap with a static bearing part.
