摘要： Systems and methods are provided for cooling an electric motor, the electric motor being fluidically coupled to a coolant sump of a gearbox. In one example, a system may include the gearbox including the coolant sump, the electric motor coupled to the gearbox, an outer shaft fluidically coupling the electric motor to the coolant sump, an inner shaft extending through each of the coolant sump and the outer shaft, and one or more surface features disposed along a portion of the inner shaft extending within the outer shaft. Upon rotation of the inner shaft during operation of the electric motor, a coolant in the coolant sump may be drawn through the outer shaft from the coolant sump into the electric motor. In this way, the coolant may be passively directed to the electric motor with minimal cost, packaging size, and system complexity and without significant losses in overall system efficiency.

摘要： A system for a driveline is provided. In one example a driveline may include a first and a second input shaft gear disposed on an input shaft. In one example, the first input shaft gear may selectively drivingly engage with the input shaft via a first clutch and the second input shaft gear may selectively drivingly engage with the input shaft via a second clutch. In another example, a first and a second counter shaft gear may be disposed on a countershaft and drivingly engage with the countershaft, wherein the first input shaft gear drivingly engages with the first countershaft gear and the second input shaft gear is drivingly engages with the second countershaft gear via an idler gear.

摘要： An electric driveline, comprising at least a first and a second electric machine, at least a first and a second output, and at least a first planetary gear set including three drivingly connected components including a sun gear, a planetary carrier and a ring gear. The first and the second electric machine are drivingly connected or connectable with the first and the second output via the first planetary gear set. At least one of the first and the second electric machine is selectively connected with the same one of the three components of the first planetary gear set via at least two different gear ratios, and/or the same one of the three components of the first planetary gear set is selectively connected with each of the first and the second output via at least two different gear ratios. The disclosure further concerns a method of operating an electric driveline.

摘要： A system and method for determining filling parameters of a wet clutch system used with a transmission is provided. The method comprises the steps of collecting information about the torque output of the torque converter of the transmission during a filling process associated with the wet clutch system, analyzing the signal associated with the torque output of the torque converter within a time period of the filling process associated with the wet clutch system, and identifying when the signal associated with the torque output of the torque converter changes with respect to the time period of the filling process of the piston to determine a filling parameter associated with the wet clutch system. The system and method eliminates a need for recalibrating the transmission and accommodates production variances for components and assembly of systems using wet clutch systems.
