  • Patent number: 7465158
    Abstract: A gear pump for an axle assembly circulates lubricating fluid from a reservoir to a fluid cooler external to the axle assembly. The gear pump includes a first housing section and a second housing section and a center section located between the first and second housing sections. An input gear mounted on an input shaft is engaged with a reduction gear, which are located in a first housing section. Two pumping gears are located in the second housing section. The center section serves as a wall and separates the first housing section from the second housing section. The gear ratio between the input gear and the reduction gear is such that the pumping gears rotate at a speed between at about 47% and at about 75% of the speed of the input shaft.

  • Patent number: 6374686
    Abstract: An shifting mechanism located outside a transmission housing which includes a gear lever and shifting rails. The shift rails are responsive to the gear lever and operate in a manner to allow for movement of a shifting rail and at the same time prevent movement of the other shifting rails.

  • Patent number: 5816101
    Abstract: A manual transmission comprising a first pivot member operatively connected to a first coupling unit on an output shaft and is selectively rotatable to drive the first coupling unit between first, neutral and second positions. A second pivot member is operatively connected to a second coupling unit on the output shaft and is selectively rotatable to drive the second coupling unit between first, neutral and second positions. A first shift rail is operatively connected to the first pivot member and is adapted to slide axially within a shift rail guide in response to rotation of the first pivot member and a second shift rail is operatively connected to the second pivot member and is adapted to slide axially within the shift rail guide in response to rotation of the second pivot member. The first and second shift rails each comprise a lock-out detent in facing relation to one another.
