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) .

Ein Mechanikstrang (100) zum Antrieb eines Kraftfahrzeugs, insbesondere eines Nutzfahrzeugs, wird beschrieben. Der Mechanikstrang umfasst ein zur Aufnahme eines Schmierstoffs abgedichtetes Gehäuse (102) mit mindestens einer Gehäusewand (104, 106, 108); eine im Gehäuse (102) angeordnete und vom Schmierstoff benetzte Mechanik (105, 107, 109) mit mindestens einer Welle zur Übertragung von Antriebsleistung in Längsrichtung; und eine Vielzahl an Kanälen (112) zur Aufnahme eines Fluids. Zumindest Abschnitte (113) der Kanäle (112) verlaufen innerhalb der Gehäusewand (104, 106, 108) in Längsrichtung und sind durch die Gehäusewand vom Schmierstoff getrennt.

A cooling system for a heavy road vehicle provided with a hybrid propulsion system includes a mechanical propulsion system and a hydraulic propulsion system. The cooling system includes a pump and a first cooling circuit including a gearbox cooling circuit a hydraulic propulsion system cooling circuit and a first radiator for cooling of a coolant flowing in the first cooling circuit. The radiator is connected in series with and located upstream of the gearbox cooling circuit and the hydraulic propulsion system cooling circuit. The cooling system is designed such that the hydraulic propulsion cooling circuit and the gearbox cooling circuit are connected in parallel.

The invention relates to a hydraulic controller for a dual-clutch gearbox in vehicles with an internal combustion engine, more particularly utility vehicles (NFZ), which can be used to operate and cool the clutches, comprising a hydraulic energy source. The invention is characterised in that the hydraulic energy source can be driven both by the internal combustion engine and by an electric machine.
摘要:
An oil tank (28) is disposed in a nacelle (7) supported on a tower (14) of a wind turbine generator (100), for storing oil used in an oil using unit (4) included in the wind turbine generator (100). The oil tank (28) at least includes: a first oil chamber (48) and a second oil chamber (50) for storing the oil; a partition wall (52) which separates the first oil chamber (48) and the second oil chamber (50); and an oil heater (56) for heating the oil in the oil tank. The partition wall (52) includes at least two openings (54a, 54b) through which the first oil chamber (48) is in communication with the second oil chamber (50) so that the oil is movable between the first oil chamber (48) and the second oil chamber (50).

A gear box for a working machine is arranged to be positioned in a first set of speed-changing gears and a second set of speed-changing gears. The gear box includes a gear box housing, an input shaft configured to receive torque, and an output shaft for supplying torque out, from the gear box, wherein the output shaft is connected to a planetary gear set of the gear box, a friction disc clutch arrangement which is arranged between a ring gear of the planetary gear set and the gear box housing for enabling connection of the ring gear to the gear box housing, and a control unit configured to controllably alternate the friction disc clutch arrangement between: an engaged state and an at least partially engaged state when the gear box is positioned in the first set of speed-changing gears, and between a disengaged state and an at least partially engaged state when the gear box is positioned in the second set of speed-changing gears. A corresponding method for controlling a gear box is also provided.
摘要:
A plurality of circumferential fins 22g are formed on an outer peripheral surface of a motor casing 22a, and a plurality of fins 22f are formed on an outer surface of a motor rear cover 22d. Lubricant circulates in a motor-casing oil passage 55 provided in the motor casing 22a, a motor-rear-cover oil passage 56 provided in the motor rear cover 22d, and a speed reduction portion B. This lubricant is cooled when flowing in the motor-casing oil passage 55 and the motor-rear-cover oil passage 56. Thus, an in-wheel motor drive device 21 is efficiently cooled.
