    The invention relates to a device for storing and transforming energy.
    It is a common problem to store, transform or even produce energy in appropriate form. For example, attempts are being made to buffer braking energy in hybrid vehicles in order to be able to use them again in ferry mode in order to save fuel. One possible embodiment of the feedback of braking energy is the generation of electrical energy by means of generators, which is temporarily stored in a corresponding battery or a supercapacitor. One problem here is the occurrence of very high powers, which pose a major challenge to electronics and storage media. Another problem is the relatively high losses of multiple energy conversion. From the point of view of simplification, therefore, mechanical accumulators such as flywheel accumulators or spring accumulators are to be preferred, but here there is the problem that it is difficult to accommodate or provide respectively adapted rotational speeds or torques.
    The object of the present invention is to avoid these disadvantages and to provide a device which can be used in a variety of ways and makes it possible to provide mechanical energy with high efficiency and adapted rotational speeds or torques.
    According to the invention, this is a device for storing and transforming energy, with a working shaft, which is coupled to an energy storage device, and which alternatively with a first transmission and a first clutch device or with a second transmission and a second clutch device with a drive shaft is connectable, wherein the transmission ratio of the first transmission is different from that of the second transmission. Energy is fed into the system via the drive shaft or removed from the system according to the invention as available. About the first and the second gear, the working shaft can be connected to the drive shaft, for example, to charge the energy storage device. In order to adapt the rotational speed or the torque to the respective conditions, the first or the second clutch device is opened or closed, so that the
    Energy storage device can be charged either fast with high torque or slow with low torque. The energy storage device is preferably designed as a spring store, but may also include a flywheel.
    It is particularly preferred if the device comprises a plurality of independently operating shafts, which are each connected by a first and a second gear together with the coupling device with the one working shaft. In this way, it is possible to initiate torque from a first energy store at the first work in the drive shaft and at the same time to use this torque to charge the associated energy storage at another working shaft.
    The coupling devices of the individual energy storage devices are appropriately controlled by a corresponding control device in order to achieve the optimum results for the respective requirement. A certain simplification of the control can be achieved in that the coupling device are designed as freewheels, so that the torque can always be transmitted only in a predetermined direction.
    In the following, the present invention will be explained in more detail with reference to the embodiment variants shown schematically in the figures. 1 shows a device according to the invention in the most general case; Fig. 2 is an extension of the device of Fig. 1; Fig. 3 is a general schematic of the device according to the invention in an axial view; 4 and 5, details of the view of Fig. 3 in different operating conditions and Fig. 6 and 7 are longitudinal sections of the device according to the invention.
    The inventive device has a drive shaft 1, on which a first gear 2 and a second gear 3 are arranged to drive a working shaft 4 and to be driven by the working shaft 4. At the working shaft 4, a spring accumulator 5 is arranged. In addition, a flywheel 6 is provided to prevent torque peaks. Bearings are indicated by 7 and 8.
    The first transmission 2 consists of a first drive gear 2a, which is designed as a spur gear and meshes with a first output gear 2b. A first
    Coupling device 9, which is designed as a switchable coupling, is provided to connect the transmission 2 optionally with the working shaft 4 frictionally. In analogous catfish, the second transmission 3 consists of a second drive gear 3a and a second output gear 3b, which selectively produce the connection to the working shaft 4 via a second clutch device 10, which is likewise designed as a switchable clutch. It is essential that the first drive gears 2a and 3a have different diameters or numbers of teeth, so that the transmission ratio of the first transmission 2 is different from that of the second transmission 3. Schematically indicated at 11 is a working machine which, depending on the operating state, supplies or picks up mechanical work.
    In Fig. 2, an extended device is shown, are coupled to the drive shaft 2, a plurality of devices of the type shown in detail in Fig. 1, which are shown schematically with 12a, 12b, 12c and 12d. Each of these devices 12a, 12b, 12c, 12d consists of its own working shaft 4 with energy storage devices 5, 6 and two gearboxes 2, 3. Due to the gear ratios of the transmission 2, 3, therefore, in each operating state, a different speed at the working shaft 4 each the devices 12a, 12b, 12c, 12d are present. The energy of one of the devices 12a, 12b, 12c, 12d for charging another device 12a, 12b, 12c, 12d can also be used for this catfish.
    In Fig. 3 shows a concrete embodiment of the invention is illustrated by the position of the individual transmission axes. The drive shaft 1 is connected via a gear consisting of a first intermediate shaft 20, a second intermediate shaft 30 with the axis 30 a and a third intermediate shaft 50 with the working shaft 4, and it is explained above. On the first intermediate shaft 20 with the axis 20a, two gears 21, 22 are arranged with different diameters. Likewise, two gears 31, 32 are provided with different diameters on the second working shaft 30. The working shaft 4 carries gears 41, 42 with different diameters.
    The second working shaft 30 is pivotally mounted about the axis 40a of the working shaft 4, which is indicated by the double arrow 39. As a result, a freewheel is realized, which is the first coupling device 9 by jenach i
    Transmission direction of the torque engagement of the gears 32 and 21 hergestelit or not.
    In an analogous manner as stated above, the third intermediate shaft 50 with its axis 50a about the axis 20a of the first intermediate shaft 20 pivotally, so that here also a freewheel is formed, there in the corresponding direction of the torque, the gear 51 in the sense of the double arrow 59 from the gear 41 can swing away.
    It should be noted that Fig. 3 is shown to illustrate the function so that all the associated gears are engaged. This is not a permissible operating state per se, since during operation one of the two transmission paths must always be open, which will now be explained with reference to FIGS. 4 and 5.
    FIG. 4 shows a first operating mode which is realized in the above sense of the first transmission 2. In this operating mode, the drive shaft 1 is connected via its gear 19 with the first intermediate shaft 20 in connection by the gear 19 meshes with the second gear 22 of the first intermediate shaft 20. This second gear 22 of the first intermediate shaft 20 further meshes directly with the gear 51 of the third intermediate shaft 50, which in turn is in communication with a first gear 41 of the working shaft 4. This is the rule of the operating mode in which the spring accumulator 5 is charged to the working shaft 4. It can be seen that the diameter of the gear 41 of the working shaft 4 is about twice as large as the diameter of the gear 19 of the drive shaft 1 so that a translation of 2: 1 and on the working shaft 4, a torque can be applied, which is about twice is great as the torque on the drive shaft. 1
    FIG. 5 shows another operating state of the device realized in the above sense of the second transmission 3. In this operating mode, in turn, the gear 19 of the drive shaft 1 with the second gear 22 of the first intermediate shaft 20 is in intervention. In this case, however, the further power flow via the first gear 21 of the second intermediate shaft 20 is directed to the second gear 32 of the second intermediate shaft 30 and further from the first gear 31 of the second intermediate shaft 30 to the second gear 42 of the working shaft 4. From the perspective of the drive shaft 1 provides this circuit is a slow-gear ratio with a relatively large gear ratio of 1:10 or more. In practice, this will
    Operating mode, however, also used for an operating condition in which torque is required at the drive shaft 1. Since there is a large transmission ratio from the point of view of the working shaft 4, torque can be exerted on the drive shaft 1 with a relatively small release of the spring accumulator 5 over a relatively long period of time.
    6 shows a section through the axes 4a of the working shaft 4, 50a of the third intermediate shaft 50 and 30a of the second intermediate shaft 30.
    It can be seen that the first gear 41 of the working shaft 40 meshes with the gear 51 of the third intermediate shaft 50. The larger diameter second gear 42 of the working shaft 4, meshes with the first gear 31 of the second intermediate shaft 30. In the background, the drive shaft 1 can be seen. On the working shaft 4, moreover, the spring accumulator 5 is arranged.
    An arcuate sliding guide 58 allows the pivoting movement of the third intermediate shaft 50.
    FIG. 7 shows a section through the axes la of the drive shaft 1, 20a of the first intermediate shaft 20 and the axis 4a of the working shaft 4.
    It can be seen that the gear 19 of the drive shaft 1 meshes with the second gear 22 of the first intermediate shaft 20. The further power transmission to the working shaft 4 is not apparent in this illustration.
