Definitions
- the invention relates to an actuating device for actuating/shifting two clutches, in particular two clutches of a hybrid transmission.
- the clutches to be actuated can preferably be positive-locking clutches, such as claw clutches.
- Each positive-locking clutch can be formed, for example, by a sliding sleeve carrier, a sliding sleeve and a clutch body.
- the actuating device has a first shift fork which can be adjusted in a first actuating direction against a first (axial) restoring force in order to actuate, in particular to open, a first clutch.
- the first shift fork can preferably engage in the sliding sleeve of the first clutch to be actuated.
- the actuating device has a second shift fork, which is adjustable in a second actuating direction for actuating, in particular for opening, a second clutch against a second (axial) restoring force.
- the second shift fork can preferably engage in the sliding sleeve of the second hitch to be actuated.
- the invention relates to a hybrid transmission with such an actuating device and a dual-clutch transmission with such an actuating device.
- a serial hybrid mode is understood to mean that the internal combustion engine no longer has a mechanical/torque-transmitting connection to the drive axle/output shaft.
- the internal combustion engine drives the first electric machine, which mainly functions as a generator, which in turn supplies the second electric machine, which mainly functions as a traction motor/drive motor, with electricity or charges a battery.
- the drive axle is driven by the second electric machine.
- a parallel hybrid mode is understood to mean that the internal combustion engine has a mechanical/torque-transmitting connection to the drive axle/output shaft.
- the second electric machine can run idle, boost or recuperate.
- a combustion engine mode is understood to mean that the second electric machine is decoupled from the drive axle and only the combustion engine (with the first electric machine) is connected to the drive axle.
- a first clutch (arranged between the internal combustion engine and the output shaft) and a second clutch (arranged between the second electric machine and the output shaft) are used in the hybrid transmission to connect the internal combustion engine and the first electric machine or to be able to connect or disconnect the second electric machine to the drive axle.
- the prior art always has the disadvantage that it is necessary for the desired switching states to be able to actuate the two clutches independently of one another, which results in greater or double the effort when using a known clutch actuation. It is therefore the object of the invention to avoid or at least alleviate the disadvantages of the prior art.
- a robust and inexpensive actuating device for independently actuating two clutches is to be provided.
- This object is achieved according to the invention in a generic device in that the first direction of actuation and the second direction of actuation are aligned opposite to one another. This means that the directions of action of the two clutches are opposite, ergo the geometric arrangement and design is chosen so that the first direction of actuation is opposite to the second direction of actuation.
- the two shift forks in an actuating device can each be subjected in the axial direction to a preload/restoring force, which causes each shift fork to move into a closed/engaged shift position, ie into a position in which the clutch to be actuated is closed , is pressed.
- each shift fork can be pressed into an open/disengaged shift position, ie into a position in which the clutch to be actuated is open.
- the actuating device can have a (preloaded) spring which is arranged axially between the first shift fork and the second shift fork in such a way that it applies the first restoring force and the second restoring force.
- a preload acts axially between the two shift forks and the two shift forks are pushed apart by the spring, so that the sliding sleeves are brought into engagement with the clutch body and both positive-locking clutches are closed.
- the actuating device can have a first spring for applying the first restoring force and a second spring have for applying the second restoring force.
- the actuating device can have a (transmission) housing relative to which the first shift fork and the second shift fork can be displaced axially in order to adjust them.
- the first spring can be arranged between the housing and the first shift fork and/or the second spring can be arranged between the housing and the second shift fork. This means that instead of a single preload spring, two individual preload springs (each acting between a shift fork and the housing) can also be used. The resulting direction of action on the shift fork must remain the same, ie opposite to one another.
- the actuating device can have an actuating actuator with two opposing effective surfaces, a first effective surface for adjustment acting on the first shift fork and a second effective surface for adjustment acting on the second shift fork.
- the first active surface or the second active surface can be brought into active engagement.
- the actuating actuator can have three switching positions. In a first shift position, for example in a middle position, the actuating actuator does not act on either of the two shift forks. In a second shift position, in which the second active surface presses on the second shift fork, the actuating actuator only acts on the second shift fork (and not on the first shift fork), so that the second shift fork pushes the associated sliding sleeve out of its engagement and opens the second clutch .
- the actuating actuator In a third shift position, in which the first effective surface presses on the first shift fork, the actuating actuator only acts on the first shift fork (and not on the second shift fork), so that the first shift fork pushes the associated sliding sleeve out of its engagement and opens the first clutch . It is thus possible to switch between three different operating modes in a simple manner.
- the actuating actuator can be designed to be self-locking. This has the advantage that the actuating actuator only has to be actuated to change between the switching positions and remains in its switching position without being actuated.
- the actuating device can have a first stop for limiting the maximum adjustability of the first shift fork in the direction of the first restoring force and/or a second stop for limiting the maximum adjustability of the second shift fork in the direction of the second restoring force.
- the first stop and/or the second stop can preferably be formed on the housing.
- the end positions of the shift forks in the closing direction are defined by stops between the respective shift fork and the housing, so that it is avoided that the shift fork in the closed end position (i.e. in the closed/engaged shift position) on the sliding sleeve of the to be actuated Coupling supported and by the relative rotation frictional heat and thus power losses and wear he testifies.
- the actuating device can have a displacement limiter for limiting the maximum adjustability in the first actuation direction and for limiting the maximum adjustability in the second actuation direction.
- This advantageously prevents one clutch from being opened before the other clutch is closed when switching between the switching states.
- the path limit thus forms a safeguard against inserting an unwanted idle and an overload protection for the spring.
- the travel limit can be dimensioned in such a way that the maximum adjustability of the two shift forks corresponds to the simple travel of the sliding sleeve to be actuated by the shift fork.
- the travel limitation can preferably be dimensioned in such a way that the maximum adjustability is limited to 5 to 8 millimeters.
- the object of the invention is also achieved by a hybrid transmission for a hybrid vehicle with such an actuating device.
- the hybrid transmission has a first drive shaft that can be connected to an internal combustion engine and a first electric machine, a second drive shaft that can be connected to a second electric machine, an output shaft that is connected to the first drive shaft and/or to the second drive shaft, a first separating clutch for the switchable connection of the first th input shaft to the output shaft and a second separating clutch for switchable connection of the second input shaft to the output shaft.
- the first separating clutch and the second separating clutch can be actuated/switched by the actuating device according to the invention.
- the object of the invention is also achieved by a double clutch transmission for a motor vehicle with such an actuating device.
- the dual clutch transmission has two drive shafts, each of which is connected to an output shaft via a partial transmission, a first clutch for shifting between two gears of a first partial transmission, and a second clutch for shifting between two gears of a second partial transmission.
- the first clutch and the second clutch can be actuated/switched by the actuating device according to the invention.
