1. An engine starting method for an internal combustion engine of a motor vehicle having an internal combustion engine and having at least one electric motor as a drive motor, wherein the internal combustion engine and the electric motor are arranged on a common shaft, wherein the internal combustion engine andor the electric motor can introduce torque into a transmission arranged downstream in the drivetrain, and a separating clutch is provided between the internal combustion engine and the electric motor, having the steps:
a. increasing the torque of the electric motor,
b. increasing the rotational speed of the electric motor and setting slip conditions at least one clutch of the downstream transmission,
c. engaging the separating clutch to a transmissible torque greater than a reserve torque of the electric motor and no greater than a maximum transmissible torque, thereby decreasing the rotational speed of the electric motor and increasing a rotational speed of the internal combustion engine,
d. reducing the transmissible torque of the separating clutch while maintaining the rotational speed of the electric motor constant when the rotational speed of the internal combustion engine has at least substantially reached the ignition rotational speed,
e. starting the internal combustion engine, disengaging the separating clutch, and ending the slip conditions of the at least one clutch of the downstream transmission,
f. ending the increase of the torque of the electric motor when starting the internal combustion engine, and
g. closing the separating clutch when the rotational speed of the internal combustion engine equals the rotational speed of the electric motor.
2. The method of claim 1, wherein the increase of the rotational speed of the electric motor takes place to such an extent that the kinetic energy thereby stored is sufficient to increase a rotational speed of the internal combustion engine to a rotational speed value at least close to the ignition rotational speed of the internal combustion engine.
3. The method of claim 1, wherein the engagement or disengagement again of the separating clutch takes place in a torque-modulated manner in multiple phases.
4. The method of claim 3, wherein the torque transmissible by the separating clutch set in a first phase is at least twice as great as the reserve torque of the electric motor.
5. The method of claim 4, wherein the transmissible torque set in a second phase is reduced in relation to the torque set in the first phase.
6. The method of claim 5, wherein the transmissible torque is reduced to the value of the reserve torque or to zero.
7. The method of claim 1, wherein the friction time of the separating clutch lies in the range from less than 50 ms to 150 ms.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A support structure for a splitter of a cutting tool having a table, comprising:
a guide device constructed to permit movement of the splitter between an operational position and a storage position;
a lock device constructed to lock and unlock the splitter at either of the operational position and the storage position, at least a part of the splitter extending upward from an upper surface of the table when the splitter is in the operational position, and the entire splitter being positioned below the upper surface of the table when the splitter is in the storage position; and
an ejecting device constructed to automatically move the splitter from the storage position to an ejected position between the operational position and the storage position upon unlocking of the splitter at the storage position, the ejecting device including an engaging member and a biasing device coupled to the engaging member,
wherein:
as the splitter is moved from the operational position toward the storage position, the engaging member engages the splitter when the splitter reaches the ejected position, and the engaging member maintains engagement of the splitter until the splitter reaches the storage position; and
the biasing device accumulates the movement force of the splitter from the ejected position to the storage position as a biasing force in a direction opposite to the moving direction of the splitter.
2. The support structure as in claim 1, wherein the ejecting device comprises an operation lever for a remote operation of the splitter for the movement from the storage position to the ejected position.
3. The support structure as in claim 1, wherein:
the splitter has an engaging hole engageable with the engaging member; and
the engaging member does not engage the engaging hole during the movement of the splitter between the operational position and the ejected position.
4. The support structure as in claim 3, wherein the biasing device is a tension spring connected between the engaging member and the guide device.
5. The support structure as in claim 1, wherein the splitter moves between the operational position and the storage position within a plane parallel to the splitter.
6. A cutting tool comprising:
a table having an upper surface;
a cutting blade constructed to cut a workpiece placed on the upper surface of the table;
a splitter proximate the cutting blade and constructed to enter a kerf of the workpiece formed by the cutting blade, the splitter being movable between a first position and a second position relative to the table, and the splitter being movable between the first position and the second position within a plane that is parallel to the splitter;
a lock device constructed to lock and unlock the splitter at the first position;
a moving device constructed to automatically move the splitter from the first position to the second position upon unlocking of the splitter at the first position by the lock device, the moving device comprising a first biasing device arranged and constructed to apply a biasing force to the splitter to move the splitter from the first position to the second position; and
an engaging device coupled to the first biasing device and arranged and constructed to engage and disengage the splitter, so that the biasing force is applied to the splitter when the engaging device engages the splitter,
wherein the engaging device can engage the splitter as the splitter moves from the second position to the first position and the engaging device can disengage the splitter as the splitter moves from the first position to the second position by the biasing force of the first biasing device.
7. The cutting tool as in claim 6, wherein:
the first biasing device comprises a tension spring; and
the engaging device comprises an engaging member pivotally connected to the tension spring.
8. The cutting tool as in claim 6, further comprising a second biasing device constructed to bias the engaging device in an engaging direction with the splitter.
9. The cutting tool as in claim 6, further comprising an operation device coupled to the lock device, wherein the operation device includes an operation member operable at a position remote from the lock device.
10. The cutting tool as in claim 6, wherein:
substantially the entire splitter is positioned below the upper surface of the table when the splitter is in the first position; and
at least a part of the splitter extends upward from the upper surface of the table when the splitter is in the second position.
11. The cutting tool as in claim 6, wherein the first biasing device is configured to accumulate the moving force of the splitter from the second position to the first position as the biasing force in a direction opposite to the moving direction of the splitter.
