  • Auxiliary oil pump system
    Patent number: 10514089
    Abstract: An auxiliary oil pump system for a gearbox, comprising: an auxiliary battery; a controller electrically connected to the auxiliary battery; and an auxiliary oil pump driven by the controller using a self-adaptive process, wherein the self-adaptive process comprises: the controller receives current operational pressure signal and compared the current operational pressure signal to a pressure threshold; if the current operational pressure signal is bigger than the pressure threshold, the auxiliary oil pump keeps current rotational speed; if the current operational pressure signal is smaller than the pressure threshold, the auxiliary oil pump improves the rotational speed by a pre-determined speed.
    Type: Grant
