摘要： Methods and systems for operating a driveline that includes a dual clutch transmission are described. In one example, clutches of the dual clutch transmission may be cooled via activating and adjusting a flow rate of an electric pump. Further, driveline operating modes may be entered or exited in response to clutch operating conditions so that driveline robustness may be enhanced.

摘要： An object is to reduce the load on a driving device for turning a screw shaft (2) in a cooling liquid discharge apparatus (10) for use in a ball screw apparatus (100) used in a machine tool or the like to make the apparatus compact and to prevent an increase in the manufacturing cost. The cooling liquid discharge apparatus (10) according to the invention has a housing (14) that is provided with proximity portions (5d, 6f) that extend radially inwardly to be close to the screw shaft 2 and reservoirs (11, 12, 13) that temporally store cooling liquid (8), which are arranged alternately along the axial direction, and discharge ports (5e, 6e, 6g) through which cooling liquid (8) is discharged from the reservoirs (11, 12, 13).

摘要： An electric oil pump control method for operating a transmission of a hybrid vehicle which is driven by a first motor, a second motor, and an engine is provided. The method includes determining a number of revolutions of a low-pressure pump of an electric oil pump based on lubrication flow amount of the first motor, lubrication flow amount of the second motor, cooling flow amount of the first motor, and cooling flow amount of the second motor and determining a number of revolutions of a high-pressure pump of the electric oil pump based on control flow amount of a clutch of the transmission and lubrication flow amount of a rotation driver included in the transmission. A maximum value is determined of the determined number of revolutions of the low-pressure pump and the determined number of revolutions of the high-pressure pump as a number of revolutions of the electric oil pump.

摘要： A thermally actuated flow control valve comprises a wax filled actuator assembly including a guide, a piston, a cup and a diaphragm. The cup is disposed at the guide first end and defines a cavity that receives a thermally activated pellet. The thermally activated pellet, diaphragm and piston act in concert to exert a variable actuating force as a temperature of a fluid increases between a first temperature T1 and a second temperature T2. The valve is arranged so that the cup and wax are directly exposed to fluid flowing through the valve and a peripheral shoulder of the cup acts as a valve member to control flow through the valve. One end of the guide also acts as a valve member to control flow between an inlet and outlet of a return flow pathway.

摘要： A solenoid fluid control valve is disclosed for controlling fluid flow. The solenoid fluid control valve may comprise a transceiver that receives a signal via a controller area network (CAN) bus, and a micro controller unit that decodes the signal to determine a temperature. The micro controller unit may send a signal to a driver circuit based on the temperature. The driver circuit may send a current through a coil in response to the signal, wherein an armature moves in response to the current through the coil. The movement of the armature may direct a cooling fluid flow.

摘要： To improve workability and sealing performance of a coolant when a plurality of nuts in a ball screw are brought into contact with one another, the plurality of nuts being coupled to one another, assembled to one threaded shaft and cooled by flowing the coolant through through-holes formed in the plurality of nuts in axial directions of the plurality of nuts. The ball screw includes counterbores of the through-holes formed on opposing end faces of both of adjoining nuts, and a ring-shaped sealing member inserted thereto. The counterbores are formed such that a depth of one counterbore is larger than a length of the sealing member, and the a depth of the other counterbore is smaller than the length of the sealing member, and such that circumferential positions of the counterbores of the adjoining nuts face each other when a desired preload is exerted.
