  • Patent number: 12264736
    Abstract: A lubricant device is configured for supplying lubricant to a planetary carrier of a planetary gearset. A planetary bolt passes through and extends beyond an opening in the planetary carrier to form an axially projecting end area. A collecting tray is configured for guiding lubricant to flow along the collecting tray to the planetary bolt during use. The collecting tray has an annular intermediate element fixed to the collecting tray when assembled, and which faces axially toward the planetary carrier. The intermediate element has first and second radial projections that are spaced axially. At its projecting end area, the planetary bolt has corresponding spaced first and second fixing contours, enabling the first radial projection to be latched into the first fixing contour and the second radial projection to be latched into the second fixing contour to form an axially secure arrangement of the collecting tray and the planetary bolt.

  • Publication number: 20030137121
    Abstract: The offset axle for buses has a housing in which a differential is located, said differential being connected to two axle shafts; and a suspension for connecting the housing to the vehicle. Said suspension has single or multiple part spring carriers which consist of corelessly, completely cast metal. Humps can be provided in the area of the curvature between the spring element and the housing in order to increase strength.
