Abstract
A drive arrangement for driving a work machine includes a motor configured to generate a torque, and a transmission apparatus configured to transmit the torque from the motor to the work machine. The transmission apparatus includes a fluid coupling and at least one controllable torque transmitter configured to control transmission of the torque from the motor to the work machine.
Claims18
A drive arrangement for driving a work machine, said drive arrangement comprising:
- a motor configured to generate a torque;
- and
- a transmission apparatus configured to transmit the torque from the motor to the work machine, said transmission apparatus including a fluid coupling and at least one controllable torque transmitter configured to control transmission of the torque from the motor to the work machine,
- wherein the fluid coupling is cooled by load-free driving by the motor.
A work machine, comprising at least one drive arrangement which includes a motor configured to generate a torque, and a transmission apparatus configured to transmit the torque from the motor to the work machine, said transmission apparatus including a fluid coupling and at least one controllable torque transmitter configured to control transmission of the torque from the motor to the work machine, wherein the fluid coupling is cooled by load-free driving by the motor.
A method for operating a drive arrangement for a work machine, comprising:
- temporarily interrupting a torque transmission between a motor and a fluid coupling of the drive arrangement, or
- temporarily interrupting a torque transmission between the fluid coupling and the work machine,
- wherein the torque transmission is interrupted between the fluid coupling and the work machine by separating the motor from the work machine, and further comprising:
- powering up the motor to a predetermined speed;
- re-establishing the torque transmission between the fluid coupling and the work machine;
- driving the work machine by using a torque transmission from the motor via a transmission apparatus to the work machine;
- and
- driving the fluid coupling by the motor without load to cool the fluid coupling, during or after powering up the motor.
