  • Patent number: 10907396
    Abstract: A rear vehicle assembly includes a body structure defining an opening having a first side edge and a second side edge and including a tailgate that is movable relative to the structure between at least one open position, in which the opening of the structure is accessible, and a closed position, in which the tailgate closes the opening of the structure, wherein the tailgate comprises at least a first side edge and a second side edge. The assembly includes an opening and closing device fixing the tailgate to the structure. The opening and closing device includes at least a first jack and a second jack, wherein the first and second jacks are each fixed between the structure and the first side edge.

  • Patent number: 8840509
    Abstract: A fluid supply system is provided for cooling and lubricating a transmission of an automobile, which includes, but is not limited to a cooling channel for cooling the transmission and a lubrication channel for lubricating the transmission. The lubrication channel communicates with the cooling channel via a shift valve. The shift valve is adapted to provide at least a first valve status, by which the cooling channel is connected to the lubrication channel via only one first valve path, and a second valve status, by which the cooling channel is connected to the lubrication channel via at least the first valve path and by which the cooling channel is connected in addition via a second valve path to a bypass channel bypassing the lubrication channel. Since at least two different valve statuses optimized for low and high power are provided, it is possible to reduce unnecessary spin losses over the whole range of applied powers.

  • Publication number: 20070000728
    Abstract: The apparatus of the present invention provides a multiple path fluid flow architecture for cooling and lubricating an automatic transmission. More precisely, the apparatus of the present invention is adapted provide a first flow rate of transmission fluid to meet the transmission cooling requirements, and a second reduced flow rate of transmission fluid adapted to meet the transmission lubrication requirements. In this manner, a high flow rate may be provided to cool the transmission and a reduced flow rate may be provided to lubricate the transmission such that the cooling capacity of the system is increased without reducing the efficiency of the transmission.
