Description

Field of the Invention

[0001] The present invention relates to a control device for a transmission, the control device having an actuator configured to generate a movement to move a transmission element of the transmission, in particular a switching fork, wherein the control device has a determination device configured to determine a control signal that describes the control state of the transmission element. Background Art

[0002] Control devices for transmissions, in particular motor vehicle transmissions, are generally known in the prior art and are used, for example, to control transmission elements, in particular claw elements of claw clutches. Here, for example, an actuator is provided which generates a rotational movement, for example by means of an electric motor, and this rotational movement can be converted into a linear movement by various elements of the control device. For example, a switching fork that engages with the transmission element to be controlled can be moved by means of the control device.

[0003] Here, it is also known from the prior art that it is advantageous for the operation of the transmission to monitor the state of the control device or the transmission element to be controlled. In other words, it is advantageous to be able to determine whether the transmission element has been set to the desired state or what state the transmission element is currently in. Here, various solutions are known from the prior art, such as axial displacement measurement, which can detect the axial position or axial displacement change of the transmission element along the rotational axis of the transmission. However, implementing such axial displacement measurement in a transmission is very complex.

[0004] In addition, a spring mechanism in the torque path can be used to enable the actuator to move between an initial position and a final position in any case, even when a so-called tooth-to-tooth position (Zahn-auf-Zahn-Stellung) is established at the transmission element. In this case, the spring mechanism is loaded such that after the tooth-to-tooth position is released by unloading the spring mechanism, the transmission element can move to its closed state, more precisely its engaged state. Therefore, the actuator can operate regardless of the blocking state, which significantly simplifies the control of the actuator. Thus, if a spring mechanism, such as a spring element, is located in the torque path of the control device, a determination device that only adapts to the operating state or position of the actuator cannot achieve an absolute determination of the state of the transmission element. Summary of the Invention

[0005] It is an object of the present invention to provide an improved control device for a transmission, in particular one that can clearly determine the state even when a spring mechanism is used.

[0006] This object is achieved by a control device having the features of claim 1. Advantageous designs are the subject of the dependent claims.

[0007] As described, the present invention relates to a control device for a transmission, such as a switchable transmission for a motor vehicle. The control device is configured to move a transmission element of the transmission, such as a switching fork. Thus, the control device can move the described transmission element to at least two different switching positions, in particular an open position and a closed position. The described transmission element can be connected to at least one further transmission element, such as a switching pawl of the transmission, such that the switching pawl can also be moved to the described switching states by the movement of the aforementioned transmission element.

[0008] By means of the control device, in particular an associated determination device or a determination device belonging to the control device, the control state of the transmission element can be described by means of a control signal. In other words, the determination device is configured to determine a control signal that describes the control state of the transmission element.

[0009] The present invention is based on the recognition that the determination device has a first detection mechanism and a second detection mechanism. The first detection mechanism is configured to detect first orientation information that describes the orientation, in particular the rotation angle, of a driving element on the driving side. The second detection mechanism is configured to detect second orientation information that describes the orientation, in particular the rotation angle, of a driven element on the driven side. Wherein, the driving element and the driven element are coupled by means of a spring mechanism. Wherein, the determination device is configured to determine the control state based on the first orientation information and the second orientation information. In other words, a superior determination device is provided to determine the control state of the transmission element. The control state is determined based on the information detected by means of the first detection mechanism and the second detection mechanism.

[0010] Here, the first detection mechanism is associated with the driving element on the driving side and can detect the first orientation information that describes the orientation of the driving element on the driving side. For example, the driving element on the driving side can be a first shaft, a first shaft portion, or a mechanical element on the first shaft or the first shaft portion, such as a first gear or a first sector gear. The first detection mechanism can here detect the orientation of the driving element, for example its current rotation angle or the change in the rotation angle. Similarly, the second detection mechanism is associated with the driven element on the driven side and is configured to detect its orientation, that is, to detect the second orientation information that describes the orientation of the driven element on the driven side. For example, the driven element can also be a second shaft, a second shaft portion, or a mechanical element on the second shaft or the second shaft portion, such as a second gear or a second sector gear.

[0011] The drive element on the drive side and the driven element on the driven side can be arranged on the same shaft, which is divided into different shaft sections, for example. The drive element and the driven element can also be arranged on different shafts that are in the same torque path. In other words, the movement generated by the aforementioned actuator is first conducted into the drive element on the drive side and then into the driven element on the driven side. The drive element is arranged closer to the actuator than the driven element, where the driven element is closer to the transmission element to be actuated than the drive element. The spring mechanism is located in the torque path between the drive element and the driven element.

[0012] The drive element and the driven element are directly coupled, for example, or indirectly coupled by means of a spring mechanism. The spring mechanism transfers the torque conducted into the drive element to the driven element. Also as described above, as long as the spring mechanism is arranged between the drive element and the driven element so as to transfer the movement from the drive element to the driven element accordingly, the spring mechanism can be arranged in any part of the torque path. For this, the spring mechanism does not have to be arranged directly at the drive element and / or the driven element, although this is also possible.

[0013] As described at the beginning, if a tooth-to-tooth position or other blocking state occurs with respect to the transmission element to be actuated, the drive element can be moved to its final position by the actuator, whereby the spring mechanism is preloaded due to the relative movement between the drive element and the driven element while the driven element remains fixed. Here, a relative movement occurs between the drive element and the driven element that remains fixed in the blocking state, which is permitted by the spring mechanism but causes preloading of the spring mechanism. Once the aforementioned blocking state is released, for example, the tooth-to-tooth position is released by rotating the transmission element, the spring mechanism can be unloaded again and also moves the driven element to its final position.

[0014] Since the first orientation information of the drive element and the second orientation information of the driven element are detected, all of the aforementioned states can be described by the first detection mechanism and the second detection mechanism. Therefore, it is possible to directly detect what state the drive element is currently in and what state the driven element is currently in, so that the actuating device or the transmission device, in particular the transmission element, can be determined unambiguously. The spring mechanism can be selected in particular such that torque can be transmitted in a normal operating state, and the spring mechanism does not accumulate elastic potential energy (Einfedern) to a significant extent. In other words, the spring stiffness of the spring mechanism is selected such that under the usually occurring actuating forces or torques, the spring mechanism only accumulates elastic potential energy insignificantly, and thus the torque can be transmitted from the drive element to the driven element through the spring mechanism. If the above-mentioned blocking state occurs, the torque input into the spring mechanism exceeds a certain limit torque, thereby preloading the spring mechanism. This is particularly likely to occur if the driven element remains fixed and the driven element is thus unable to move. As described, when the blocking state is released, the driven element then moves to its final position through the preloaded spring mechanism.

[0015] As described, the second detection mechanism detects the second orientation information that describes the orientation of the driven element. According to the design of the actuating device, the second detection mechanism can be configured to detect the second orientation information at the driven section of the output shaft of the actuating device that is configured as the driven element, and the output shaft is particularly directly connected to the transmission element. The "output shaft" of the actuating device is understood to be the shaft that leads the torque from the actuating device to the transmission element to be actuated. The output shaft, for example, leads out of the housing of the actuating device at least in part, so that the torque can be transmitted from the output shaft to the transmission element. The output shaft, for example, carries specific mechanical elements, such as gears or sector gears, which are connected to the corresponding tooth parts on the transmission element, such as the tooth parts of a switching fork. Here, an indirect connection can also be provided between the transmission element and the output shaft, such as an additional transmission stage.

[0016] This design enables the detection to be carried out at the part of the actuating device connected to the transmission element to be actuated, that is, the second orientation information is detected by the second detection mechanism. The output shaft, more precisely the output element of the output shaft, can be understood as the part of the actuating device that is arranged furthest downstream on the driven side. By detecting the second orientation information as far downstream as possible in the driven part of the actuating device, the tolerances in the torque path can be eliminated to the greatest extent, because these tolerances are located as "upstream" as possible of the driven element and thus do not affect the detection by the second detection mechanism. On the contrary, the second detection mechanism can detect the orientation of the driven element as directly as possible.

[0017] According to another design of the actuating device, the actuator can have an actuator shaft which is coupled directly or via an intermediate shaft to the output shaft of the actuating device, wherein the actuator shaft or the intermediate shaft or the output shaft is constructed in two parts, wherein the first shaft part on the drive side is constructed as a drive element and the second shaft part on the driven side is constructed as a driven element, and the first shaft part is coupled to the second shaft part by means of a spring mechanism. The described design proposes a shaft in two parts with a first shaft part and a second shaft part. In the context of the present application, the first shaft part can be understood as a drive element and the second shaft part can be understood as a driven element. As described at the beginning, the drive element and the driven element are kept coupled to each other by means of a spring mechanism.

[0018] Here, as long as the previously determined conditions of the torque path are maintained, i.e., the torque is introduced on the drive side into the drive part by the actuator and the torque is exported through the driven part, the shaft in two parts can be arbitrarily constructed as an actuator shaft, an intermediate shaft or an output shaft. In other words, it must be ensured that the drive element is arranged upstream of the spring mechanism in the direction of the torque flow or in the torque path, and the driven element is arranged downstream of the spring mechanism in the torque flow or in the torque path. Also as described above, the mechanical elements directly upstream and downstream of the spring mechanism do not necessarily have to be the drive element and the driven element, which is feasible and particularly advantageous in a shaft designed in two parts with a first shaft part and a second shaft part. However, the shaft part can be coupled to other mechanical elements, such as gears or sector gears arranged on other shafts, and the orientation information can be detected there. The term "shaft part" can also be understood as "shaft section".

[0019] As described above, the first shaft part and the second shaft part can be coupled directly or indirectly to each other by means of a spring mechanism. This enables the first shaft part arranged on the drive side to perform a relative movement with respect to the second shaft part in the blocked state of the second shaft part arranged on the driven side, and the spring mechanism is preloaded by this relative movement. In particular, the first shaft part can have a sleeve and the second shaft part can have a mandrel engaged in the sleeve, or the second shaft part can have a sleeve and the first shaft part can have a mandrel engaged in the sleeve, wherein a spring element of the spring mechanism is arranged between the first shaft part and the second shaft part, in particular between the inner surface of the sleeve and the outer surface of the mandrel, the first end of which is connected to the first shaft part and the second end of which is connected to the second shaft part.

[0020] The proposed design essentially provides a torsion bar, whose input part is configured as a first shaft part and whose output part is configured as a second shaft part. Here, the first shaft part can optionally be configured as a sleeve and the second shaft part as a mandrel, or the second shaft part can be configured as a sleeve and the first shaft part as a mandrel. The mandrel is engaged in the sleeve here such that the mandrel is surrounded by the inner surface of the sleeve. The spring element of the spring mechanism can be located between the sleeve and the mandrel and undergoes preloading in the manner of a torsion spring due to the relative movement, i.e., rotation, between the first shaft part and the second shaft part.

[0021] As described, the spring mechanism can have at least one torsion spring element, in particular a loaded leg torsion spring. Also as described above, here, the first end can be connected to the first shaft part and the second end can be connected to the second shaft part, or generally, the first end can be connected to the drive element and the second end can be connected to the driven element. In principle, the spring mechanism can also be integrated into other mechanical elements besides the shaft, for example with the first end located at a gear or sector gear connected to the drive element and the second end located at a shaft or gear or sector gear connected to the driven element. In principle, for example, in two opposite switching states relative to an intermediate neutral state, such as when the transmission element is to move from an initial state in a first direction and a second direction opposite to the first direction, the spring mechanism can allow relative movement between the drive element and the driven element in two rotational directions. The spring mechanism or the actuating device can also be designed to provide movement only in a single rotational direction and in the reverse direction starting from the first switching state to the second switching state.

[0022] An output gear engaged with the transmission element can be arranged on the output shaft, where the output shaft is coupled to the actuator by means of at least one input gear or sector input gear, in particular by means of an intermediate shaft. As described at the beginning, the output shaft is understood to be arranged on the driven side and used to derive the torque from the actuating device. In other words, the torque is derived from the output shaft, particularly introduced into the transmission element, through the output gear. The torque is introduced into the output shaft through the input gear or sector input gear. Here, the input gear or sector input gear can represent the drive element and the output gear can represent the driven element, which are coupled by means of the spring mechanism. The output shaft can also be configured in two parts as described above, where the first shaft part can have an input gear or sector input gear and the second shaft part can have an output gear.

[0023] Similarly as described above, the sector input gear can also be coupled to the mechanical elements of the actuating device, such as a gear on the intermediate shaft or a sector gear, or a gear on the actuator shaft of the actuator, in particular the rotor shaft of an electric motor. The described sector input gear can have a sector angle between 20° and 180°, in particular between 30° and 90°. Depending on the gear ratio selected between the previous mechanical element and the sector input gear, the rotational movement generated by the actuator is speeded up or slowed down. Here, for example, for reasons of installation space, the sector angle of the input gear can be selected to be as narrow as possible, so as to be sufficient to satisfy the movement of the transmission element without occupying unnecessary installation space.

[0024] According to another design of the actuating device, the actuator, the detection device (in particular the detection mechanism) and the drive element can be arranged in a common housing, and the driven element, in particular the driven section of the output shaft, can be led out of the housing at least partially. According to the described design, at least a part of the driven element or the part connected to the driven element, in particular the section of the output shaft connected to the driven element, can be led out of the housing. The remaining mechanisms, in particular the actuator, the first detection mechanism, the second detection mechanism, the intermediate shaft and the spring mechanism if necessary, are arranged in the common housing of the actuating device.

[0025] Therefore, the actuating device can be provided as a module or a partial assembly and integrated into the transmission. Thereby, the output shaft that must be coupled to the transmission element forms the only external interface. The remaining mechanisms described above form part of the actuating device and are arranged together in a common housing. In particular, a rotational angle sensor is used as the detection mechanism, and this rotational angle sensor can also be arranged in the common housing. The rotational angle sensor can detect, for example, the rotational angle or the change in the rotational angle of a shaft having a drive element or configured as such a drive element.

[0026] The actuating device can also have a control mechanism, which can be arranged, for example, in the form of a microcontroller on a circuit board in the common housing. The corresponding connections between the detection mechanism, the detection device and the control mechanism can also be arranged accordingly in the common housing. The detection mechanism and the detection device can be at least partially integrated into the control mechanism. The actuating device can have an external data interface, by means of which signals, such as the determined actuating state, can be transmitted from the actuating device to at least one higher-level control device.

[0027] In addition to the actuating device, the invention also relates to a transmission device comprising the actuating device described above. The invention also relates to a method for operating an actuating device for a transmission device, the actuating device having an actuator which is configured to generate a movement for moving a transmission element of the transmission device, in particular a switching fork, wherein the actuating device has a determination device which is configured to determine an actuating signal which describes the actuating state of the transmission element, wherein a first orientation information which describes the orientation, in particular the rotational angle, of a drive element on the drive side is detected by means of a first detection mechanism of the determination device, and a second orientation information which describes the orientation, in particular the rotational angle, of a driven element on the driven side is detected by means of a second detection mechanism of the determination device, wherein the drive element and the driven element are coupled by means of a spring mechanism, and wherein the actuating state is determined on the basis of the first orientation information and the second orientation information.

[0028] All advantages, details and features described with respect to the actuating device can be transferred to the transmission device and the method. Description of the Drawings

[0029] The invention will be explained below by way of examples with reference to the drawings. The drawings are schematic and:

[0030] Figure 1 show an actuating device for a transmission device;

[0031] Figure 2 show a sectional view of a part of the actuating device; and

[0032] Figure 3 show Figure 2 a perspective view of a part. Detailed Description of the Invention

[0033] Figure 1 An actuating device 1 for a transmission device, for example a switchable transmission of a motor vehicle, which is not shown in detail, is shown. The actuating device 1 comprises an actuator 2 which is configured to generate a movement for moving a transmission element 3 of the transmission device, in particular a switching fork. The actuating device 1 also has a determination device 4 which is configured to determine an actuating signal which describes the actuating state of the transmission element 3. For example, the actuating signal describes the switching state in which the transmission element 3 is located.

[0034] In the illustrated embodiment, the determination device has a first detection mechanism 5 and a second detection mechanism 6. The first detection mechanism 5 is configured to detect first orientation information, which describes the orientation, in particular the rotational angle, of the drive element 7 on the drive side. The second detection mechanism 6 is configured to detect second orientation information, which describes the orientation, in particular the rotational angle, of the driven element 8 on the driven side. Merely by way of example, in this embodiment, the drive element 7 on the drive side is arranged at the intermediate shaft through which the movement of the actuator 2 is transmitted, wherein the driven element 8 on the driven side is arranged on the output shaft of the actuating device 1. In this embodiment, the torque is transmitted from the actuator 2 to the intermediate shaft and, in particular, from the intermediate shaft to a gear arranged on the output shaft or a sector gear as shown in this embodiment by means of a gear. It can be seen that the drive element 7 and the driven element 8 are coupled to each other by a spring mechanism 9.

[0035] The determination device 4 is configured to determine the manipulation state described at the beginning based on the first orientation information and the second orientation information. In other words, the orientation of the drive element 7 is detected by the first detection mechanism 5, such that when the manipulation state changes, for example when the transmission element 3 moves from the engaged state to the disengaged state or from the disengaged state to the engaged state, the orientation of the drive element 7 changes because the rotational movement of the actuator 2 is transmitted through the drive element 7. The spring mechanism 9 hereby enables the actuator 2 to always be moved to its end position, regardless of whether a blocking state occurs with respect to the transmission element 3, for example whether a so-called tooth-to-tooth position occurs when the transmission element 3 is configured as a claw element.

[0036] For example, if the transmission element 3 moves from the disengaged position to the engaged position, the actuator 2 can perform a complete movement without stopping. If the aforementioned blocking position or blocking state occurs at the transmission element 3, which prevents the transmission element 3 from being able to move into the engaged state, the spring mechanism 9 is preloaded by the movement of the drive element 7 relative to the fixedly held driven element 8. If the blocking state is subsequently released, for example by releasing the tooth-to-tooth position, the transmission element 3 changes to the engaged state while the preloading of the spring mechanism 9 decreases.

[0037] Here, the first detection mechanism 5 can detect what state the actuator 2 is in, for example, whether the actuator has occupied its final position for the corresponding operating state. Since the drive element 7 and the driven element 8 are coupled to each other by the spring mechanism 9, but the fixed connection has been decoupled, the second detection mechanism 6 can detect what operating state the transmission element 3 is in. In other words, although the first detection mechanism 5 can detect that the actuator 2 has reached its final position, however, only the first detection mechanism 5 cannot give the absolute and defined state of the transmission element 3, because as described above, the transmission of motion can be decoupled by means of the spring mechanism 9. However, since, as described above, the orientation of the driven element 8 is also detected independently of the first detection mechanism 6 by the second detection mechanism 6, the state of the operating device 1, more precisely the transmission element 3, can be detected even if decoupling occurs, and thus, for example, the blocking state and its release can also be detected.

[0038] In Figure 1 it is shown that the drive element 7 and the driven element 8 are arranged on different axes of the operating device 1. Figure 2 , Figure 3 shows an alternative embodiment, in which the drive element 7 and the driven element 8 form different shaft sections of a common shaft. For example, Figure 2 it is shown in that the drive element 7 forms a first shaft section, which is provided with a sleeve 10. The core shaft 11 of the driven element 8 engages in this sleeve 10, and the driven element forms a second shaft section. The first shaft section and the second shaft section and thus the drive element 7 and the driven element 8 are coupled to each other by the spring mechanism 9, as described above. The distribution of the sleeve 10 and the core shaft 11 on the drive side and the driven side can be arbitrarily interchanged. In Figure 2 , Figure 3 the embodiment shown, the spring mechanism 9 directly connects the drive element 7 to the driven element 8. In Figure 1 the embodiment shown, the spring mechanism 9 is indirectly coupled to the drive element 7 and the driven element 8, because they are coupled to each other by a gear, more precisely a sector gear, and the spring mechanism 9 is arranged at this gear, more precisely at the sector gear.

[0039] In other words, the two shaft sections, more precisely the drive element 7 and the driven element 8 and the spring mechanism 9 together form a torsion bar. Here, the spring mechanism 9 is designed in terms of its spring stiffness such that the conventional motion of the actuator 2 for changing the operating state of the transmission element 3 can be transmitted without triggering a significant accumulation of elastic potential energy in the spring mechanism 9. In other words, the spring stiffness of the spring mechanism 9 is higher than the force or torque that occurs during the normal operation of the operating device 1. However, if a blocking state occurs, that is, the transmission element 3 cannot move further, the driven element 8 that is engaged or coupled to the transmission element 3 remains fixed on the output side or the driven side. As a result, the torque between the drive element 7 and the driven element 8 exceeds a specific threshold value, such that the spring mechanism 9 can be deformed and thus preloaded, as described above.

[0040] In principle, Figure 2 , Figure 3 the shaft composed of two shaft segments shown can be arbitrarily constructed as a drive shaft, an intermediate shaft or an output shaft. Depending on the specific embodiment, for example, what transmission ratio or what distance the transmission element 3 is to cover, the intermediate shaft can be omitted if necessary.

[0041] As described, the actuating device 1 can be part of a transmission. The method described above can be carried out by means of the actuating device 1. All advantages, details and features described in the individual embodiments can be fully transferred to one another, combined with one another and interchanged with one another.
