  • Patent number: 11702966
    Abstract: A fluid pan for a motor vehicle has a main pan and a secondary pan that is separate from the main pan, wherein the main pan has a main space for fluid and a passage is provided on a side wall of the main pan. The secondary pan has a secondary space and an opening, wherein the secondary pan is attached to the side wall of the main pan in such a manner that the opening of the secondary pan connects to the passage of the main pan and thus the main space and the secondary space are fluidically connected.
    Type: Grant
    Filed: November 23, 2020
    Date of Patent: July 18, 2023
    Assignee: Bayerische Motoren Werke Aktiengesellschaft

  • Patent number: 7530281
    Abstract: A gear set for differential shafts of internal combustion engines. The gear set includes a toothed wheel which can be moved parallel to its axis for adjustment of backlash. A spacer is arranged removably between tooth faces of interacting teeth of engaging toothed wheels and serves to adjust the backlash between the toothed wheels. The spacer is arranged free of play between corresponding tooth faces of the toothed wheels by way of the movable toothed wheel which can be moved with a predetermined force to the other toothed wheels.

  • Patent number: 6997077
    Abstract: A method of obtaining a desired tooth flank backlash for a transmission having at least two interlocking toothed gears, comprises applying a removable coating on at least one of the toothed gears for purposes of setting the backlash, the coating comprising a mixture containing a bonding agent and a filling material; adjusting the least two interlocking toothed gears with the coating relatively to each another essentially play-free or with only small play; and removing the coating.

  • Patent number: 6308558
    Abstract: In a method used for checking the effect of swirl ducts in multicylinder internal combustion engines, especially engines with direct injection, swirl numbers are determined with a swirl measuring device in a simultaneous cylinder that can be connected to a cylinder head and related to an engine-specific swirl tolerance band. With a sharp deviation of the swirl number from the swirl tolerance band as a function of the swirl number outside the swirl tolerance band, the corresponding swirl duct and/or filling channel in the cylinder head is subsequently made or designed to be smaller or larger in cross section in one duct section.
