Definitions
- the invention relates to a motor vehicle with at least one electric drive machine for driving the motor vehicle and with at least one linkage, which is at least between a coupling position, in which the electric drive machine is coupled to a drive wheel of the motor vehicle in a torque-transmitting manner, and a decoupling position, in which the electric Prime mover is decoupled from the drive wheel, can be switched. Further aspects of the invention relate to a linkage for such a motor vehicle and a method for operating a motor vehicle.
- Such coupling gears make it possible, for example, to interrupt torque transmission between the electric drive motor and the drive wheels of a motor vehicle as required (decoupling position) and thus, for example, to allow the motor vehicle to coast while it is operating as a ferry and to establish torque transmission (coupling position) in order to drive the drive wheels by means of to allow the drive machine.
- DE 19923316 A1 describes a drive system for a motor vehicle with a starter and generator unit arranged in a drive train with a drive shaft.
- the starter and generator unit has an electric machine that can be operated as an electric motor with a starter function or as an electric generator, and a planetary gear.
- the object of the present invention is to provide a motor vehicle with a coupling mechanism that can be operated with little effort, a corresponding coupling mechanism for such a motor vehicle, and a method for operating such a motor vehicle.
- a first aspect of the invention relates to a motor vehicle with at least one electric drive machine for driving the motor vehicle and with at least one linkage which is coupled at least between a coupling position, in which the electric drive machine is coupled to a drive wheel of the motor vehicle in a torque-transmitting manner, and a decoupling position, in which the electric drive machine is decoupled from the drive wheel, can be switched.
- the coupling gear can preferably be automatically switched between the coupling position and the decoupling position.
- the motor vehicle can, for example, comprise a control unit, by means of which, for example, a switching device of the linkage can be controlled.
- a switching device of the linkage can be controlled.
- the latter can switch to the coupling position or the decoupling position as required and thereby couple or decouple the drive machine to the drive wheel.
- the term drive wheel is to be understood as meaning a drive element which is in direct contact with a contact area of the motor vehicle and accordingly has at least one rim and one tire connected to it.
- the at least one coupling gear for torque-transmitting coupling is provided with exactly one side of a drive axle of the motor vehicle and includes a positive-locking clutch for switching between the coupling position and the decoupling position.
- the at least one coupling mechanism is provided for torque-transmitting coupling with precisely one side of a drive axle of the motor vehicle means that the at least one coupling mechanism is designed and provided for individual wheel drive of the drive wheel. It is clear that this can also include any double tires on the drive wheel.
- the form-fitting clutch is to be understood as meaning a clutch in which, in the coupling position, torque is transmitted by positive engagement, ie by form-fitting of the respective clutch elements.
- positive engagement clutches advantageously do not require any holding force in order to maintain torque transmission.
- form-fitting clutches there is also no slippage between the respective coupling elements, via which torque can be transmitted in the coupling position, or is being transmitted.
- the torque-transmitting coupling between the electric drive machine and the drive wheel can be produced exclusively by switching from the decoupling position to the coupling position. Provision can therefore be made for no further clutches to be interposed for torque transmission between the drive wheel and the electric drive machine.
- the electric drive machine can be coupled to the drive wheel in the coupling position via the at least one coupling gear without a differential gear, in other words without the interposition of a differential gear of the motor vehicle and thus without a differential gear.
- the motor vehicle comprises a plurality of drive wheels, coupling gears and electric drive machines. At least one linkage and at least one electric drive unit can be assigned to each of the drive wheels. If the motor vehicle has four-wheel drive, for example, then the motor vehicle can have four drive wheels, four electric drive units and four linkages. As a result, for example, the respective front drive wheels assigned to a front part, i.e. the front of the motor vehicle, can be decoupled by shifting the (front) coupling gear assigned to these front drive wheels and setting the decoupling position, whereas the rear drive wheels assigned to a rear part, i.e.
- the rear of the motor vehicle be coupled by shifting the (rear) linkage and adjusting the coupling position and thus used to drive the motor vehicle.
- the front drive wheels are in what is known as “coasting operation” and, in contrast to the rear drive wheels, are not used to drive the motor vehicle. It is of course also conceivable that the front drive wheels are used to drive the motor vehicle and the rear drive wheels are in coasting mode.
- the coupling gear can be designed as a gearwheel stage, in particular an intermediate gearwheel stage, which can be switched between the coupling position and the decoupling position.
- This allows easy integration into a transmission, in particular Spur gear, the motor vehicle.
- the transmission can preferably be designed as an automatic transmission.
- the invention is based on the general finding that the coupling to precisely one side of the drive axle of the motor vehicle and the resulting individual wheel drive enable the driving wheel to be coupled and decoupled as required.
- the motor vehicle can be operated particularly efficiently if it has several, for example four, drive wheels, which can each be driven with a linkage and each with an electric drive motor and, as required, for example two of the drive wheels can be decoupled while the motor vehicle is moving by the respective decoupling position of the two linkages assigned to these drive wheels.
- the positive-locking coupling can be held in the coupling position and in the uncoupling position without any effort.
- the coupling gear comprises a first gear wheel, which is in at least indirect engagement with the drive motor, and a second gear wheel, which can be coupled to the first gear wheel in a torque-transmitting manner using the positive-locking clutch and is at least indirectly coupled to the drive wheel in a rotationally fixed manner.
- first gear wheel which is in at least indirect engagement with the drive motor
- second gear wheel which can be coupled to the first gear wheel in a torque-transmitting manner using the positive-locking clutch and is at least indirectly coupled to the drive wheel in a rotationally fixed manner.
- the positive-locking clutch comprises a first clutch element which is at least indirectly non-rotatably coupled to the first gear and a second clutch element which is at least indirectly non-rotatably coupled to the second gear.
- the positive-locking clutch comprises a connecting element which is coupled in a torque-proof manner at least indirectly to the first gear wheel and at least indirectly to the first clutch element.
- the connecting element allows a particularly simple configuration of the first coupling element.
- the connecting element can be reversibly detachable, in other words detachable without destroying it, for example by means of a spline, which can also be referred to as a spline, at least indirectly coupled to the first gear.
- the connecting element is designed as a fixed sleeve.
- the fixed sleeve can preferably have internal teeth with teeth running along an axis of rotation of the first gear wheel.
- This internal toothing can mesh with a complementary toothing, which can be associated with a first shaft that is non-rotatably connected to the first gear wheel.
- the connection of the internal toothing with the complementary toothing can preferably be designed as a play-free press fit.
- the form-fitting clutch includes a blocking element.
- the blocking element is designed to prevent switching from the decoupling position to the coupling position when there is a speed difference between the first gear wheel and the second gear wheel.
- the blocking element is designed to release a relative movement between the first clutch element and the second clutch element that causes switching from the decoupling position to the coupling position when the speeds of the first gear wheel and the second gear wheel are the same.
- the positive-locking clutch is designed as a claw clutch. This is advantageous because such a claw coupling is particularly robust and simple on the one hand and requires no effort on the other is necessary in order to maintain the coupling position or the decoupling position, but only for switching between the coupling position and the decoupling position, ie for switching from the coupling position to the decoupling position and vice versa.
- the linkage is integrated into a spur gear of the motor vehicle. This is advantageous since the linkage can be arranged in a particularly space-saving manner and accommodated in a housing of the spur gear. Preferably, the linkage can be designed as an intermediate gear stage of the spur gear.
- a second aspect of the invention relates to a linkage for a motor vehicle according to the first aspect of the invention.
- the coupling gear can be switched at least between a coupling position, in which the electric drive machine is coupled to a drive wheel of the motor vehicle in a torque-transmitting manner, and a decoupling position, in which the electric drive machine is decoupled from the drive wheel.
- the at least one linkage is designed for torque-transmitting coupling with precisely one side of a drive axle of the motor vehicle and includes a positive-locking clutch for switching between the coupling position and the decoupling position. This linkage can be operated particularly efficiently and with little effort.
- a third aspect of the invention relates to a method for operating a motor vehicle with at least one electric drive machine, which is designed to drive the motor vehicle and with at least one linkage, which is coupled to a drive wheel of the motor vehicle at least between a coupling position in which the electric drive machine transmits torque is, and a decoupling position, in which the electric drive machine is decoupled from the drive wheel, can be switched.
- the at least one linkage is provided for torque-transmitting coupling with precisely one side of a drive axle of the motor vehicle and includes a positive-locking clutch for switching between the coupled position and the uncoupled position.
- the coupling gear comprises a first gear wheel, which is at least indirectly engaged with the drive motor, and a second gear wheel, which can be coupled to the first gear wheel in a torque-transmitting manner using the positive-locking clutch and is at least indirectly coupled to the drive wheel in a rotationally fixed manner.
- the positive-locking clutch includes a first clutch element, which is at least indirectly coupled to the first gear wheel in a torque-proof manner, and a second one Coupling element which is at least indirectly rotationally coupled to the second gear.
- the positive-locking clutch includes a blocking element which, in the method, prevents switching from the decoupling position to the coupling position, while the electric drive machine compensates for a speed difference between the first gear wheel and the second gear wheel.
- the electric drive motor can be used before a torque-transmitting coupling between the drive wheel and the drive motor via the linkage to accelerate the motor vehicle , first compensate for the speed difference between the first and second gear. Only when the speed is the same, i.e. the speed difference between the first gear wheel and the second gear wheel has been balanced, does the locking element release the shift from the decoupling position to the coupling position and thus the torque-transmitting coupling between the electric drive motor and the drive wheel via the coupling gear. Switching from the decoupling position to the coupling position can now take place. As soon as the coupling position is set, torque can be transmitted from the electric drive machine to the drive wheel and used to drive or accelerate the motor vehicle.
- the transmission of torque from the electric drive machine to the drive wheel can be quickly interrupted by switching from the coupling position to the decoupling position.
- the drive wheel can also be used as a non-driven wheel, which is advantageous for so-called coasting of the motor vehicle, for example.
- Fig. 1 is a schematic perspective view of a spur gear, which a
- Coupling gear comprises, and is coupled to an electric drive machine which is used to drive a drive wheel of a motor vehicle shown highly abstracted;
- Fig. 2 is a schematic sectional view of the linkage shown in half section.
- FIG. 1 shows a schematic perspective view of a motor vehicle K, which comprises a total of four electric drive machines 10, four spur gears SG with four linkages 20 and four drive wheels 100.
- One of the linkages 20 is assigned to each of the spur gears SG.
- one of the linkages 20 is integrated into one of the spur gears SG of the motor vehicle K in each case.
- Each of the drive machines 10 is coupled to one of the spur gears SG.
- Each of the spur gears SG can also be coupled to one of the drive wheels 100 in that the respective coupling gear 20 of the respective spur gear SG is switched from a decoupling position ES to a coupling position KS.
- the respective drive wheel 100 is coupled to the respective drive machine 10 in a torque-transmitting manner, whereas the transmission of torque between the drive wheel 100 and the drive machine 10 is interrupted in the decoupling position ES.
- the respective electric drive machine 10 is decoupled from the drive wheel 100 in the decoupling position ES of the respective linkage 20 .
- this enables selective driving of the respective drive wheels 100, consequently, an individual wheel drive of each of the drive wheels 100 allows.
- each of the drive wheels 100 can be driven independently of the other drive wheels 100 by the electric drive machine 10 assigned to it.
- the spur gear SG comprises a first gear shaft 102, which is coupled to the electric drive motor 10 of the motor vehicle K in a torque-transmitting manner.
- the torque-transmitting and thus non-rotatable coupling between the first transmission shaft 102 and the drive engine 10 is carried out, for example, via a splined shaft end section 103, in other words an end section of the first transmission shaft 102, which has splines.
- the first transmission shaft 102 is in at least indirect engagement with the electric drive machine 10 via this spline.
- a first gear wheel 104 is also coupled in a torque-proof manner to the first gear shaft 102 .
- the first gear wheel 104 meshes with a first gear wheel 42 of the linkage 20 .
- the first toothed wheel 42 of the linkage 20 is thus in direct engagement with the drive motor 10 , that is to say it is indirectly coupled to the drive motor 10 .
- the spur gear SG also includes a second gear shaft 106 which is coupled to the drive wheel 100 to transmit torque.
- the first transmission shaft 104 serves to transmit torque on the drive side and the second transmission shaft 106 to transmit torque on the output side.
- the torque-transmitting and thus non-rotatable coupling between the second transmission shaft 106 and the drive wheel 100 is carried out, for example only, via internal splines 107 of the second transmission shaft 106.
- the drive wheel 100 engages with the internal splines 107 via a drive axle 110 shown in broken lines in Fig. 1 and thereby coupled in a torque-proof manner to the second gear shaft 106 of the spur gear SG.
- the linkage 20 is provided for torque-transmitting coupling to precisely one side of the drive axle 110 of the motor vehicle K, as a result of which the drive wheel 100 can be driven individually.
- the transmission of the torque between the electric drive machine 10 and the drive wheel 100 take place without the interposition of a differential gear.
- the torque can therefore be transmitted between the electric drive machine 10 and the drive wheel 100 without a differential gear (without a differential gear).
- a second gear wheel 108 of the spur gear SG is also coupled in a torque-proof manner to the second gear shaft 106 .
- the second gear wheel 108 meshes with a second gear wheel 52 of the linkage 20 .
- the second gear 52 of the linkage 20 is at least indirectly coupled to the drive wheel 100 in a rotationally fixed manner.
- Fig. 2 shows the linkage 20 in an enlarged sectional view and thereby in half section.
- the coupling mechanism 20 comprises a positive-locking clutch 40 designed as a claw clutch for shifting between the coupling position KS and the decoupling position ES.
- the first gear wheel 42 is connected in one piece to a shaft 46 .
- the first gear wheel 42 and thus the shaft 46 rotate in the circumferential direction U about an axis of rotation x, which is also a central axis of the shaft 46 and of the first Gear 42 represents.
- the first gear 42 can be coupled to the second gear 52 in a torque-transmitting manner using the positive-locking clutch 40 by the positive-locking clutch 40 and thus the coupling gear 20 being switched between the coupling position KS and the decoupling position ES.
- the positive-locking clutch 40 includes a first clutch element 44 which is coupled to a connecting element 70 .
- the first coupling element 44 is bidirectional and displaceable relative to the connecting element 70 according to a relative movement RB indicated by a double arrow parallel to the axis of rotation x and thus translationally.
- the first coupling element 44 and the connecting element 70 each have teeth, in particular splined teeth, which engage with one another. As a result, the first coupling element 44 and the connecting element 70 remain engaged during the relative movement RB.
- the first clutch element 44 is indirectly, namely via the connecting element 70 and the shaft 46, non-rotatably coupled to the first gear 42.
- a second clutch element 54 of the linkage 20 is coupled in a torque-proof manner (and thus transmits torque) to the second gear wheel 52 at a common coupling region 56 .
- this coupling area 56 for example, respective splines of the second clutch element 54 and the second gear wheel 52 can mesh.
- the connecting element 70 is designed as a fixed sleeve.
- the second gear wheel 52 is rotatably mounted on the shaft 46 via respective needle bearings 58a, 58b, as can also be seen in FIG.
- respective roller bearings 60a, 60b which can be designed as ball bearings, for example, the linkage 20 is supported on a housing of the spur gear SG, which is not shown in detail here, and is mounted therewith.
- the first gear wheel 42 or the shaft 46 is supported at least indirectly on the housing via the roller bearing 60a, whereas the second gear wheel 52 is supported at least indirectly on the housing via the further roller bearing 60b.
- the relative movement RB of the first clutch element 44 allows the coupling gear 20 to be shifted either into the decoupling position ES, in which the electric drive machine 10 is decoupled from the drive wheel 100, or into the coupling position KS, in which the first gear wheel 42 transmits torque with the second Gear 52 and thus the electric drive machine 10 as a whole is coupled to the drive wheel 100 .
- the first coupling element 44 which can also be referred to as the first claw element, is shown in the coupling position KS only in sections and with dots, but it can be seen that the first coupling element 44 in the coupling position KS is connected to the second coupling element 54, which can also be referred to as a second claw element, is engaged, that is coupled to transmit torque.
- the decoupling position ES are the first Coupling element 44 and the second coupling element 54, on the other hand, are separated from one another, i.e. decoupled, so that the power flow KF between the first coupling element 44 and the second coupling element 54 is interrupted and, accordingly, no torque can be transmitted between these coupling elements in 44, 54.
- the coupling mechanism 20 includes a shifting device 22 which is shown schematically in FIG. 1 and partially in FIG.
- the switching device 22 can exert a switching force on the first clutch element 44 in order to switch the latter back and forth between the coupling position KS and the uncoupling position ES according to the relative movement RB.
- the switching device 22 can be controlled by a control unit ECU.
- the control unit ECU can be assigned to the motor vehicle K, the spur gear SG or, for example, the linkage 20 .
- the electric drive machine 10 can also be controlled using the control unit ECU.
- the positive-locking clutch 40 includes a locking element 80.
- the blocking element 80 releases the relative movement RB between the first clutch element 44 and the second clutch element 54, which causes the shifting from the decoupling position ES into the coupling position KS.
- the speed difference can be compensated for by the electric drive machine 10 . Additionally or alternatively, the speed difference can also be compensated by the blocking element 80, so that the blocking element 80 can be used for synchronization.
- the blocking element 80 can generally assume the function of a synchronizing ring and/or be designed as a synchronizing ring.
- the blocking element 80 supports the electric drive machine, which can also be referred to as an electric motor, or electric motor for short, during synchronization.
- the electric drive machine 10 adjusts the speed of the first gear wheel 42 to the speed of the second gear wheel 52 at least to a large extent while the motor vehicle K is driving.
- the linkage 20 enables a particularly efficient operation of the motor vehicle K, since the linkage 20 allows a needs-based coupling and decoupling between the electric drive machine 20 and the drive wheel 100, particularly when the motor vehicle K has the plurality of electric drive machines 20, linkages 20 (Or spur gears SG, each with a coupling gear 20) and drive wheels 100, which can be coupled and decoupled independently of each other.
- the present positive-locking clutch 40 can maintain the coupling position KS or the decoupling position ES without force. After the relative movement RB has taken place and after the coupling position KS or the decoupling position ES has been set, no further holding force is required, for example by the switching device 22, in order to prevent an undesired movement of the first coupling element 44 parallel to the axis of rotation x.
- the blocking element 80 and/or the electric drive motor 10 enable a particularly rapid reduction in the speed difference between the first gear wheel 42 and the second gear wheel 52 during operation of the motor vehicle K and thus a particularly quick adjustment of the speed equality between these gear wheels 42, 52 particularly short switching times for switching between the coupling position KS and the decoupling position ES can be realized, with any noticeable jolt or unwanted acoustic feedback during switching being able to be at least dampened or even eliminated.
- the motor vehicle K with the coupling gear 20 permits synchronization between the first gear wheel 42 and the second gear wheel 52, i.e. synchronization on the input and output sides, while at the same time maintaining the coupling position KS or decoupling position ES at least largely without loss.
