  • Patent number: 8522638
    Abstract: A Shift fork is provided for shifting gears of a transmission assembly of a gear box that includes, but is not limited to a basin for collecting splash oil. The basin includes, but is not limited to an outlet channel for guiding the collected oil away from the basin. By means of the basin splash oil can be collected and led via the outlet channel to nearly every place of the transmission assembly, where additional lubrication is wanted. This provides a better lubrication of parts of the transmission assembly with low effort.

  • Patent number: 8312858
    Abstract: A lubrication system and method are disclosed. The system includes a main engine bearing and a crankshaft in operational association with the bearing. The crankshaft includes an end having a cavity with a power transmitting element (e.g., splines). The cavity can receive and engage a mating mechanism to transmit power thereto. The crankshaft further includes a first oil passage that is disposed within the end and a second oil passage that extends from the main engine bearing into the crankshaft. The first oil passage intersects the second oil passage. The system can also include a pump mechanism for circulating lubricating oil from the main engine bearing to the crankshaft through the second oil passage and the first oil passage, and to the cavity to lubricate the power transmitting element. During engine operation, a constant supply of lubricating oil can be provided to the power transmitting element to reduce component wear.

  • Patent number: 8167758
    Abstract: An axle assembly having an axle assembly with first and second sumps for holding a lubricant. A rotating ring gear associated with a differential can rotate through the lubricant in the first sump to cause a portion of the lubricant to cling to the ring gear. A portion of the lubricant that has clung to the ring gear can be removed from the ring gear and transferred to the second sump. The lubricant in the second sump can be drained to lubricate teeth of a pinion that is in meshing engagement with the ring gear and/or to lubricate bearings that support the pinion. A related method is also provided.
