摘要:
A drive unit is in working connection with a power takeoff by way of a wrap spring, which has a predetermined number of turns between its two ends and which serves as a load torque interlock. The wrap spring has a first actuating area assigned to a selected direction of rotation on at least one of its two ends and a second actuating area assigned to the opposite direction of rotation, where the first actuating area can be brought into nonrotatable working connection with the drive unit and the second actuating area into nonrotatable working connection with the power takeoff. By the application of a drive torque produced by the drive unit on the first actuating area, a first change in the diameter of the turns in the direction away from a braking device can be obtained, with the result that the frictional connection between the turns and the braking device is at least weakened. By the absorption of a restoring torque which originates from the power takeoff and acts in the opposite direction of rotation on the second actuating area after the drive has been turned off, a second change in the diameter of the turns in the direction toward the braking device can be obtained, with the result that the frictional connection between the turns and the braking device is increased.

An actuating drive for transmitting drive torque to a power takeoff, comprising a drive unit; a braking device comprising a cylindrical surface; and a wrap spring having a plurality of turns which are concentric to the cylindrical surface, a pair of ends, a first actuating area on one of the ends, and a second actuating area on one of the ends. When the drive unit exerts a drive torque in a first direction, the first actuating area is nonrotatably connected to the drive unit, the turns undergo a diameter change away from the cylindrical surface, and the second actuating area is nonrotatably connected to the power takeoff for transmitting drive torque. When the drive torque is interrupted, the turns undergo a diameter change toward the cylindrical surface and frictionally engage the cylindrical surface to block transmission of restoring torque from the power takeoff to the drive unit.

An actuating device for applying actuating forces in a friction clutch device for engaging and disengaging a friction clutch assembly of the friction clutch device. The torque transmission device comprises the actuating device for transmission of torque between a drive unit and a transmission which also includes the friction clutch device. A method for installing a torque transmission device of this type. Various aspects relate to setting of a pre-load on a bearing of the actuating device, setting an over-dead-point configuration for a compensation spring associated with at least one rotary member of the actuating device, setting a rotation movement range for the rotary member and/or an axial movement range for an actuating element which can be displaced axially by rotation movement imparted to the rotary member, and producing either a normally engaged or disengaged characteristic in a normally-engaged or normally-disengaged friction clutch assembly with the compensation spring.

A device for lubricating a rolling bearing. The inventive device comprises a lubricant dispenser (1) connected to the lubricating point of the rolling bearing (7) and a measuring unit (8) allocated to the rolling bearing (7) for detecting the condition of the bearing. The lubricant dispenser (1) comprises a lubricant container with a supply of lubricant (2), a discharge device with an electromotor drive (3) and a control device (4) lined with the measuring device (8). The control device (4) of the lubricant dispenser (1) emits control signals to the electromotor drive (3) at certain intervals prompting it to discharge small amounts of lubricant and changes the discharge times and/or the duration of the discharge intervals if the measuring signal emitted by the measuring unit (8) exceeds a defined value. In this case, a signal for displaying an incipient bearing defect is also emitted.

A coupling arrangement includes a first clutch device for establishing a working connection between an electric machine and an internal combustion engine and a second clutch device for establishing a working connection between at least one of the machines and a takeoff. Each of the two clutch devices has its own clutch components in the form of at least one piston and a predetermined number of clutch elements. By means of the piston in question, a pressure space is at least essentially sealed off from a cooling space, which holds the clutch elements. Each of the pressure spaces of the two clutch devices has its own supply line, whereas only one of the cooling spaces of the two clutch devices has its own supply line, the cooling space of the other clutch device being connected by a line leading to the cooling space of the first-mentioned clutch device.

摘要:
A clutch arrangement has a clutch device with a clutch housing capable of rotating around an axis of rotation, where the clutch device is designed to establish or to separate a working connection between a drive and a take-off and is provided with clutch components in the form of a piston and clutch elements. The piston produces a seal between a pressure space and a cooling space holding the clutch elements. The pressure space or the cooling space is connected to a supply unit so that it can be supplied with fluid medium, by connecting at least one supply line of the clutch device is connected to an infeed line of a gearbox and possibly by connecting at least one discharge line of the clutch device is connected to an outfeed line of the gearbox. An actuating line for a first supply line is assigned to the clutch device. The first supply line is independent of the infeed line for a second supply line or of the outfeed line for a discharge line.
