    The invention relates to a drive system for a vehicle having a primary drive shaft having a primary engine which is driveabverbindverbindbar with a main drive train and a PTO, wherein in the PTO a planetary gear is arranged, which at least one connected to the primary machine or connectable PTO, one with at least one secondary machine Has connected or connectable secondary drive shaft and connected to a PTO or connectable power take-off shaft. Furthermore, the invention relates to a method for operating this drive system.
    Agricultural vehicles such as tractors or the like are usually equipped with PTO units (PTO = Power Take Off) for driving implements. Such PTO units typically consist of two to four mechanical gear stages to provide different PTO speeds for different applications and implements. Due to the mechanical drive connection, these speeds depend directly on the speed of the primary machine, which is generally designed as an internal combustion engine.
    WO 2012/110617 A1 describes a power take-off unit wherein a load-sensitive pump designed as a variable displacement pump is used in combination with a hydraulic motor to provide different rotational speeds at the power take-off shaft. However, the range of different speeds is very limited by the arrangement.
    The object of the invention is to avoid this disadvantage and to provide a high speed flexibility for the PTO in the simplest possible way. Another object is to provide an alternative drive in a simple manner.
    According to the invention, this is done by the secondary drive shaft can be braked via a first brake device and the PTO shaft via a second brake device.
    In this case, in at least a first operating range of the vehicle, the secondary drive shaft of the planetary gear be braked by a first braking device, in particular held, and braked in at least a second operating range of the vehicle, the output shaft of the planetary gear by a second braking device, in particular held. This allows a high variability in the operation.
    In a preferred embodiment of the invention in which a large number of different modes of operation is possible, the primary machine - for example an internal combustion engine - can be drive-connected to the main drive train via a first clutch and to the auxiliary drive train via a second clutch. The first and the second clutches can be designed as friction clutches, in particular as a double clutch. It is particularly advantageous if the first drive shaft can be drive-connected to the main drive train via at least one third clutch. The third clutch can be designed in a simple manner as a dog clutch.
    As a result, in at least one operating region of the vehicle, preferably the second operating region, the primary engine can be separated from the secondary driveline via a first clutch and / or from the main driveline via a second clutch.
    The vehicle can be directly at least partially, in particular exclusively, driven by the secondary engine when the auxiliary drive train is connected via a third clutch to the main drive train.
    The secondary machine may be formed by a hydraulic motor or an electric motor.
    As a braking device, for example, a friction brake can be used. This makes it possible by slipping operation to apply a variable braking torque to the first drive shaft or the output shaft. In a particularly simple embodiment, it is provided that at least one braking device is designed as a dog clutch.
    The invention will be explained in more detail below with reference to the non-limiting figures.
    1 schematically shows a drive system according to the invention in a first embodiment, and FIG. 2 shows a drive system according to the invention in a second embodiment variant.
    The figures each show a drive system 10 for a vehicle. The drive system 10 has a - formed for example by an internal combustion engine - primary engine 12, which via a primary drive shaft 11, a first clutch 13 and a second clutch 14 with a main drive train 15 for driving a rear axle 16 and front axle 17 of the vehicle and / or a PTO 18 for driving a PTO shaft 19 (PTO drive) can be connected. The first clutch 13 and second clutch 14 may be formed as a double clutch 134, as shown in the figures.
    In the main drive train 15 designed as a multi-group transmission 20 shift transmission is arranged, wherein the multi-group transmission 20, a main gear 21 for a plurality of gear stages 1, 2, 3, 4, a downstream range group transmission 22 for two different transmission ranges H and L and an upstream reversing stage 23 for forward drive F and reverse R has
    In the auxiliary drive train 18, a planetary gear 25 is disposed between the second clutch 14 and the PTO shaft 19. The example, as a three-shaft gear - with the elements sun gear, planet carrier and ring gear-executed planetary gear 25 has a connectable to the primary engine 12 PTO shaft 24, connected to a secondary machine 26 second secondary drive shaft 27 and connected to the PTO 19 PTO shaft 28 on. In this case, secondary drive shaft 24, secondary drive shaft 27 and power take-off shaft 28 are connected to different elements of the planetary gear 25. The auxiliary drive shaft 24 can be braked or held by a first braking device 29. Furthermore, a second braking device 30 is provided for braking or holding the power take-off shaft 28.
    The main drive train 15 and the auxiliary drive train 18 can be directly connected to one another via a gear stage 31 and a third clutch 32, bypassing the dual clutch 134. In this way, it is possible to use the secondary machine 26 exclusively for driving the vehicle.
    Fig. 1 shows a first embodiment of the invention, in which the secondary machine 26 is designed as a hydraulic motor, with which a drive torque, or a braking torque can be applied.
    In the second embodiment of the invention shown in Figure 2, the secondary machine 26, however, is designed as an electric motor. In this case, another electric machine 33 may be drive-connected to the primary drive shaft 11. The further electric machine 33 can be operated by a motor or generator, and thus apply an additional drive or braking torque to the primary drive shaft 11.
    With the arrangement described, the following modes of operation can be realized, among others: A) Drive of the vehicle only via primary machine 12 without PTO drive:
