  • Patent number: 6526934
    Abstract: A drive arrangement for a vehicle including a drive assembly having a crankcase, and an oil sump arranged to close off the crankcase on one side. The oil sump and the crankcase have a common connecting plane. The oil sump has a first sidewall with an indent arranged to protrude into the oil sump, which indent is configured to receive a differential gear. The indent has an orifice for receiving an axle shaft projecting out of the differential gear. The orifice further has a center axis that runs through the connecting plane. The oil sump has a second wall with an orifice for an output shaft of the gear. A tunnel-like indentation is provided in the oil sump so as to connect the orifice to the indent for the differential gear. The tunnel-like indentation is configured so as to encase the output shaft relative to the oil sump.

  • Patent number: 6510827
    Abstract: An accessory drive for the valves of an internal combustion engine, especially an Otto engine, especially for a motor vehicle, with at least one camshaft, which is divided into two camshaft halves. A camshaft gear wheel is provided between the two halves of the camshaft. A hydraulic camshaft adjuster is installed between the two halves of the camshaft. This adjuster is designed as a thrust bearing for each of the two halves of the camshaft, and each camshaft half has a hydraulic fluid connection extending via the associated thrust bearing to the camshaft adjuster.

  • Patent number: 6378478
    Abstract: A control device for camshaft systems of an internal combustion engine with n banks of cylinders arranged in a V-shaped configuration. The control device has a distribution system with a first distributor gear which intermeshes with an output gear arranged on a crankshaft of the internal combustion engine. The distribution system has m<n secondary distributor gears which intermesh with the first distributor gear and transmit a driving force to the n camshaft systems of the n banks of cylinders through n endless-chain drives.
