    ment is delivered from the internal combustion engine and the electric machine to the gearbox and on to the vehicle's drive wheels. Since both the internal combustion engine and the electric machine are connected to the planetary gear, the maximum possible torque delivered by the internal combustion engine and the electric machine will be limited by one of these drives, whose maximum torque is lower than the highest torque of the other drive unit. In the event that the maximum torque of the electric machine is lower than the maximum torque of the internal combustion engine, the electric machine will not be able to generate a sufficiently large reaction torque to the planetary gear, which means that the internal combustion engine can not transmit its maximum torque to the gearbox and to the vehicle - wheels. Thus, the highest transferable torque to the gearbox is limited by the strength of the electric machine. Especially, when strong acceleration of the vehicle is desired and the electric machine is not able to generate a sufficiently large reaction moment, heat will be generated in the electric machine in an undesired manner.
    The document US-Al-2003/0078127 shows a drive system for a vehicle with an internal combustion engine and an electric motor, which are connected to a planetary gear. The planetary gear holder of the planetary gear unit is connected to an input shaft in a gearbox. The planetary gear holder and the planetary gear's sun gear can be fixedly connected to a sleeve, so that the electric motor and the input shaft of the gearbox can rotate as a fixed rotating unit.
    In a vehicle, the available space for the drive device is often limited. If the drive device comprises a number of components, such as an internal combustion engine, an electric machine, a gearbox and a planetary gear, the construction must be compact. For this reason, it is desirable that the dimensions of the electric machine be small, which means that the power of the electric machine and the highest possible generated torque are limited.
    There are also requirements for high reliability and high operational reliability of the components that were in the drive yesterday.
    SUMMARY OF THE INVENTION The object of the present invention is to provide a drive device for a vehicle, which drive device has a compact construction.
    A further object of the invention is to provide a drive device for a vehicle, which drive device has high reliability and high operational reliability. Yet another object of the invention is to provide a drive device for a vehicle, which drive device has a low weight. Yet another object of the invention is to provide a drive device for a vehicle, which drive device has a low manufacturing cost.
    These objects are achieved with the drive device of the kind mentioned in the introduction, which is characterized by the features stated in the characterizing part of claim 1.
    These objects are also achieved with the vehicle, which comprises such a drive device of the kind mentioned in the introduction, which is characterized by the features stated in the characterizing part of claim 13.
    These objects are also achieved with the method for controlling the drive device of the kind mentioned in the introduction, which is characterized by the features stated in the characterizing part of the patent claim 14.
    By firmly connecting the output shaft of the internal combustion engine to the input shaft of the gearbox via the planetary gear with the locking mechanism, a desired acceleration of the vehicle can be obtained while the dimensions and power of the electric machine can be limited, resulting in a compact drive with limited dimensions. Thus, the highest torque that the electric machine can generate can also be lower than the highest torque that the internal combustion engine can generate. With the sleeve provided with first splines '10, which is designed to be able to engage with second and third splines on the first and second moving components of the planetary gear, a drive device according to the invention is obtained which has a compact construction, has high reliability and high operational reliability and has low weight and low manufacturing cost.
    According to an embodiment of the invention, the first movable component is a planet gear holder and the second movable component is a sun gear. Thus, the power from the internal combustion engine in the second position of the sleeve will pass through the sun gear, the sleeve, the planet gear holder and on to the gearbox, which means that the planet wheels do not absorb torque. This means that the dimension of the planet gears can only be adapted to the torque of the electric machine instead of the torque of the internal combustion engine, which in turn means that the planet gears can be made with smaller dimensions. Thus, a drive device according to the invention is obtained which has a compact construction, low weight and low manufacturing cost.
    According to a further embodiment, the locking mechanism is designed as an annular sleeve, which substantially concentrically encloses the planetary gear holder. Thereby a drive device according to the invention is obtained which has a compact construction with low weight and low manufacturing cost.
    According to a further embodiment, the annular sleeve is provided with peripheral recesses, which co-operate with the planet wheels arranged on the flat wheel holder. Thus, the weight of the sleeve will decrease, which reduces the weight of the drive device and the manufacturing cost.
    According to a further embodiment, the sleeve is moved between the first and second positions by means of a force element which substantially concentrically encloses the input shaft of the gearbox or the output shaft of the internal combustion engine. This results in a compact design with low weight and low manufacturing cost.
    According to a further embodiment, a bearing is arranged between the sleeve and the force element, which bearing allows the sleeve to rotate relative to the force element. The power element “IO element can thus be designed so that it does not have to rotate, which means that the power element's construction can be simplified. The reliability and operational reliability of the drive device can then be increased.
    According to a further embodiment, at least one spring is arranged to surface the sleeve from the first to the second position. The spring can work independently of the force element or cooperate with the force element to move the sleeve. This can simplify the construction of the power element and increase the reliability and operational reliability of the drive device. Should the power element fail, the spring strives to move the sleeve to the second position, to allow operation of the vehicle.
    A planetary gear usually comprises three components which are rotatably arranged in relation to each other, namely a sun gear, a planet gear holder and a ring gear. With knowledge of the number of teeth of the sun gear and the ring gear, the mutual speeds of the three components can be determined during operation. According to the present invention, one of the components of the planetary gear is connected to an output shaft of the internal combustion engine.
    This component of the planetary gear thus rotates at a speed corresponding to the speed of the output shaft of the internal combustion engine. A second component of the planetary gearbox is connected to an input shaft of the gearbox. This component of the planetary gearbox thus rotates at the same speed as the input shaft of the gearbox. A third component of the planetary gear is connected to a rotor of an electric machine. This component of the planetary gear thus rotates at the same speed as the rotor of the electric machine if they are directly connected to each other. Alternatively, the electrical machine may be connected to the third component of the planetary gear via a transmission having a gear ratio. In this case, the electric machine and the third component of the planetary gear can rotate at different speeds. The speed of electrical machines can be regulated steplessly. During operating times when the input shaft to the gearbox is to be given a desired speed, a control unit calculates, with knowledge of the combustion engine speed, the speed at which the third component must be driven in order for the input shaft to the gearbox to obtain the desired speed. A control unit activates the electric machine so that it gives the third component the calculated speed and thus the input shaft to the gearbox the desired speed.
    Additional advantages of the invention will become apparent from the following detailed description.
    BRIEF DESCRIPTION OF THE DRAWINGS In the following, as an example, a preferred embodiment of the invention is described with reference to the accompanying drawings, in which: Fig. 1 shows a vehicle in a side view with a drive device according to the present invention, Fig. 2 shows a cross-sectional view of the drive device according to the present invention with a locking mechanism in a first position, Fig. 3 shows a cross-sectional view of the drive device according to the present invention with the locking mechanism in a second position, and Fig. 4 shows a circuit diagram of a method for controlling the drive device according to present invention.
    DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION Fig. 1 shows a side view of a vehicle 1, which comprises a drive device 2 according to the present invention. An internal combustion engine 4 is connected to an electric machine 6 and a gearbox 8 via a planetary gear 10. The gearbox 8 is further connected to the drive wheel 12 of the vehicle 1.
    Fig. 2 shows a cross-sectional view of the drive device 2 according to the present invention. The planetary gear 10 comprises movable components in the form of a sun gear 18, a ring gear 20 and a planet gear holder 22. According to the embodiment shown, the sun gear 18 is connected to the output shaft 14 of the internal combustion engine 4 and forms a continuous unit. It is also possible to connect the output shaft 14 of the internal combustion engine 4 to the ring gear 20 or the planet gear holder 22.
    The electric machine 6 comprises a stator 24 and a rotor 26. The stator 24 is fixedly connected to the vehicle 1 and therefore does not rotate. The rotor 26 is coupled to the ring gear 20 of the planetary gear 10 and can thus rotate relative to the stator 24. According to the embodiment shown, the ring wheel 20 and the rotor 26 of the electric machine 6 form a continuous unit. It is also possible to design the ring gear 20 and the rotor 26 as separate units, which are connected to each other.
    An input shaft 27 of the gearbox 8 is coupled to the planet gear holder 22, which comprises a number of gears, called planet gears 28. These are mounted on the planet gear holder 22 with, for example, roller bearings 36. In the embodiment shown, the sun gear 18 is also mounted on the planet gear holder. 22 with roller bearings 37. The teeth 30 of the planet gears 28 engage with teeth 32, 34, which are formed on the sun gear 18 resp. ring gear 20.
    During engine braking, the driver releases the vehicle's accelerator pedal (not shown). The input shaft 27 of the gearbox 8 then drives the electric machine 6 at the same time as the internal combustion engine 4 and the electric machine 6 engine brakes. The electrical machine 6 here generates electrical energy which is stored in a battery 50 in the vehicle. This operating condition is called regenerative burning. The electric machine 6 which thus functions as a generator. When the electric machine 6 functions as a generator, the electric machine 6 exerts a counteracting torque on the torque from the gearbox 8, which results in the vehicle 1 being braked, since the gearbox 8 is coupled to the drive wheel 12 of the vehicle 1.
    When accelerating the vehicle 1, an increased torque shall be delivered from the internal combustion engine 4 and the electric machine 6 to the gearbox 8 and further to the drive wheels 12 of the vehicle 1. Since both the internal combustion engine 4 and the electric machine 6 are connected to the planetary gear 10, the greatest possible torque supplied by the internal combustion engine 4 and the electric machine 6 to be limited by any of these drive units 4, 6 whose maximum torque is lower than the highest torque of the other drive unit 4, 6. If the maximum torque of the electric machine 6 is lower than the highest torque of the internal combustion engine 4, the electric machine 6 will not be able to generate a sufficiently large reaction torque to the planetary gear 10, which means that the internal combustion engine 4 can not transmit its maximum torque to the gearbox 8 and on to the drive wheel 12 of the vehicle 1. Thus, the highest transferable torque to the gearbox 8 is limited by the strength of the electric machine 6. In particular, when strong acceleration of the vehicle 1 is desired and the electric machine 6 is not able to generate a sufficiently large reaction moment, heat will be generated in the electric machine 6 in an undesired manner.
    By firmly connecting the output shaft 14 of the internal combustion engine 4 to the input shaft 27 of the gearbox 8 with a locking mechanism 38 via the planetary gear 10, a desired acceleration of the vehicle 1 can be obtained while limiting the dimensions and power of the electric machine 6, resulting in a compact drive 2 with limited dimensions. Thus, the highest torque that the electric machine 6 can generate can also be lower than the highest torque that the internal combustion engine 4 can generate.
    The locking mechanism 38 is fl removable between a first and a second position. In the first position the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox 8 are allowed to rotate at different speeds via the planetary gear 10. In a second position the locking mechanism 38 connects the output shaft 14 of the internal combustion engine 4 to the input shaft 27 of the gearbox 8 via the planetary gear 10.
    The locking mechanism 38 comprises a sleeve 40 provided with first splines 41, which in the first position engages with second splines 43 on a first movable component, which is constituted by the planet gear holder 22 of the planetary gear 10 and in the second position also engages with third splines 45 on a of the planetary gear 10 second movable component, which is constituted by the sole1. As mentioned above, the planetary gear holder 22 is connected to the input shaft 27 of the gearbox 8 and the sun gear 18 is connected to the output shaft 10 of the internal combustion engine 4. The locking mechanism 38 is formed as an annular sleeve 40 which substantially concentrically encloses the planetary gear holder 41. arranged on the sleeve 40 are formed around the inside of the sleeve 40 and extend in the axial longitudinal direction of the sleeve 40 corresponding to and slightly exceeding the total length of the second splines 43, which are arranged on the planet wheel holder 22 and the third splines 45, which are preferably arranged on the sun gear 18. Preferably, the sun wheel 18 is provided with a mandrel 51, which on its periphery is provided with the third splines 45, which engage with the sleeve 40. The second splines 43 arranged on the periphery of the planet gear holder 22 and the third splines 45 , which are arranged on the periphery of the 51 end 51 are preferably formed around the entire circumference of the 51 end 51 and the planet gear holder 22. Thus, a spline joint is formed when the first splines 41 on the sleeve 40 engage with the second and third splines 43, 45 on the planet gear holder 22 and the sun gear 18, respectively.
    With increased radial extension of the shaft 51 and the planet wheel holder 22, the torque absorbed by the sleeve 40 decreases, which in turn means that the dimensions of the sleeve 40 can be made smaller. Thus, a compact construction with low weight can be obtained. The sleeve 40 is provided with peripheral recesses 53, which are designed so that the sleeve 40 does not come into conflict with the planet wheels 28 arranged on the planet gear holder 22. The recesses 53 have an axial extension which allows the sleeve 40 to be displaced in the axial direction without coming in contact with the planet gear 28.
    A force element 54 in the form of a pneumatic cylinder, with an axially movable piston 61 arranged therein, which together substantially concentrically encloses the input shaft 27 of the gearbox 8, is arranged to surface the sleeve 40 between the first and second position. It is also possible to arrange the power element 54 so that it concentrically encloses the output shaft 14 of the internal combustion engine 4. The power element 54 can also be constituted by a hydraulic cylinder or a linear notor. Preferably, a number of springs 57 are provided to surface the sleeve 40 from the first to the second position. The springs 57 can operate independently of the pneumatic cylinder 54 or co-operate with the cylinder 54 to surface the sleeve 40. Thereby the construction of the power element can be simplified and the reliability and reliability of the drive device 2 can be increased. Should the power element 54 fail or a drive source, such as a compressed air source 56 for the power element 54, cease to function, the springs 57 strive to move the sleeve 40 to the second position, so that the sun gear 18 and the planet gear holder 22 are connected and a power transmission over the planetary gear 10 is possible. that propulsion of the vehicle 1 down there is also made possible. Even if the electric machine 6 fails, the vehicle 1 will be able to be propelled when the sun gear 18 and the planet gear holder 22 are coupled to the sleeve 40. In the embodiment shown, the springs 57 are designed as screw springs, which act with a pressure force on a first pressure surface 63 of the piston. 61 in the cylinder 54. When the pneumatic pressure decreases on a second pressure surface 65 of the piston 61, the piston 61 is displaced by the spring frame 57. When the pneumatic pressure increases on the second pressure surface 65 of the piston 61 and exceeds the compressive force of the springs 57, the piston 61 will be displaced by of the pneumatic pressure. Thus, it is the force from the pneumatic pressure which moves the sleeve 40 from the first to the second position and the force from the cap frame 57 which moves the sleeve 40 from the second to the first position.
    As an alternative to several springs 57, a single coil spring can be arranged in the cylinder, which coil spring substantially concentrically encloses the input shaft 27 of the gearbox 8.
    As an alternative to the cylinder 54 concentrically arranged with the shaft 27 included in the gearbox 8, the force element 54 can be constituted by a control fork (not shown), which is arranged to surface the sleeve 40 between the first and second position.
    A bearing 67 is arranged between the sleeve 40 and the pneumatic cylinder 54, which bearing allows the sleeve 40 to rotate relative to the cylinder 54. The bearing 67 allows the sleeve 40 to rotate relative to the cylinder 54, so that the cylinder 54 can be designed so that it does not need to rotate. Thus, the piston 61 in the cylinder will also not rotate relative to the cylinder 54, which means that seals between the cylinder 54 and the piston 61 can be simplified, which means that the construction of the cylinder 54 can be simplified. The bearing 67 according to that in f1g. 2 is a radial deep groove ball bearing, which can also absorb axial forces, so that the piston 61 in the cylinder 54 can surface the sleeve 40 axially. Another type of bearing is also conceivable, such as an axial bearing or an angular contact bearing. The output shaft 14 of the internal combustion engine 4, the rotor 26 of the electric machine 6, the input shaft 27 of the gearbox 8 and the sleeve 40 are rotatably arranged about a common axis of rotation 48.
    The sleeve 40 is axially displaceable along the input shaft 27 of the gearbox 8 at the displacement between the first and second position. In case the output shaft 14 of the internal combustion engine 4 is instead connected to the planetary gear holder 22, the sleeve 40 is axially displaceable with the output shaft 14 of the internal combustion engine 4 at the displacement between the first and second position.
    To displace and move the sleeve 40 from the first to the second position, the internal combustion engine 4 and the electric machine 6 are controlled so that a torque-free state is formed between the output shaft 14 of the internal combustion engine 4 and the planetary gear 10. A control unit 55 is also used for this. is adapted to control the electrical machine 6 so that during certain applicable operating conditions it uses stored electrical energy to supply driving force to the input shaft 27 of the gearbox 8 and during other operating uses the input shaft 27 of the input shaft 27 utilizes kinetic energy to extract and store electrical energy. The control unit 55 thus senses speed and / or torque of the output shaft 14 of the internal combustion engine 4, the input shaft 27 of the gearbox 8 and the rotor 26 of the electric machine 6, so as to control the internal combustion engine 4 and the electric machine 6 so that a torqueless state is formed between the internal combustion engine. 4 output shaft 14 and gearbox input shaft 27. When the torqueless state is reached, the sleeve 40 is displaced and moved to the second position by the control unit activating the compressed air source 56, which supplies the compressed air to the pneumatic cylinder 54 via a line 58, so that the cylinder 54 for the sleeve 40. The control unit 55 is connected to the internal combustion engine 4, the gearbox 8, the electric machine 6 and the compressed air source 56 via electrical conductors 60. The control unit 55 thus controls the movement of the sleeve 40. It is also possible to arrange a separate control unit for compressed air source 56.
    The control unit 55 is thus adapted to control the sleeve 40 and also adapted to determine at which times the electric machine 6 should operate as a motor and at which occasions it should operate as a generator. To determine this, the control unit 55 12 can receive current information from the above-specified suitable operating parameters. The control unit 55 may be a computer with suitable software for this purpose. The control unit 55 also controls the flow of electrical energy between a battery 50 and the stator 24 of the electrical machine 6. At times when the electric machine 6 operates as a motor, stored electrical energy is supplied from the battery 50 to the stator 24. At times when the electric machine 6 acting as a generator, electrical energy is supplied from the stator 24 to the battery 50.
    Fig. 3 shows a cross-sectional view of the drive device 2 according to the present invention with the locking mechanism 38 in the second position. In the second position, the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox are fixedly connected to each other with the sleeve 40 via the planetary gear 10. To enable this to move the sleeve 40, the control unit 55 first controls the internal combustion engine 4 and the electric machine 6 so that an instantaneous state is formed between the output shaft 14 of the internal combustion engine 4 and the input shaft of the gearbox, which is explained above in connection with fi g. 2.
    In the second position of the sleeve 40, the force from the internal combustion engine 4 will pass through the sun gear 18, the sleeve 40, the planet gear holder 22 and on to the gearbox 8, which means that the planet wheels 28 do not absorb torque. This means that the dimension of the planet gears 28 can be adapted only to the torque of the electric machine 6 instead of the torque of the internal combustion engine 4, which in turn means that the planet gears 28 can be made with smaller dimensions. Thus a drive device 2 according to the invention is obtained which has a compact construction, low weight and low manufacturing cost.
    When the vehicle 1 has been accelerated to the desired speed, the cylinder 54 is controlled so that the sleeve 40 is returned to the first position. At the same time, the internal combustion engine 4 and the electric machine 6 are controlled by the control unit 55 so that a torqueless state is formed between the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox 8. When the torqueless state is reached, the sleeve 40 is moved to the first position. When the sleeve 40 has been returned to the first position, the vehicle 1 can be driven by both the internal combustion engine 4 and the electric machine 6.
    Fig. 4 shows a circuit diagram concerning a method for controlling a drive device 2 according to the present invention. The method according to the invention is comprised of a first step a) where the internal combustion engine 4 and the electric machine 6 are controlled so that a substantially torque-free state is formed between the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox 8.
    In a next step b) the output shaft of the internal combustion engine 4 and the planetary gear 10 are connected to each other by moving a locking mechanism 38, which comprises a sleeve 40 provided with first splines 41, from a first position in which the output shaft of the internal combustion engine 4 14 and the input shaft 27 of the gearbox 8 are allowed to rotate at different speeds via the planetary gear 10, and to a second position in which the sleeve 40 firmly connects the output shaft 14 of the internal combustion engine 4 to the input shaft 27 of the gearbox 8 via the planetary gear.
    According to a further step or an alternative step c), the sleeve 40 is moved by spring force from the first to the second position.
    The stated components and features stated above can be combined within the scope of the invention between different specified embodiments.
