Description

Technical Field

[0001] The present invention relates to an operating device for operating a transmission element, in particular a sliding sleeve, the operating device comprising an operating element and a spring device, wherein the operating element can be moved at least between a disengaged position and a coupled position in order to operate the transmission element, and the spring device is configured to apply a spring force to the transmission element in a tooth-to-tooth state between a tooth portion of the transmission element and a tooth portion to be coupled. Background Art

[0002] Actuating devices for actuating transmission elements are generally known from the prior art. For example, such actuating devices are used to actuate a transmission element, such as a sliding sleeve, between a disengaged position and a coupled position. For this purpose, the actuating device has an actuating element that can be coupled to a spring device. The spring device can thus exert a spring force on the actuating element. For example, when the toothing of the transmission element and the toothing to be coupled are in a tooth-on-tooth position, if the actuating element is moved against the action of the transmission element, the spring device exerts a spring force on the transmission element. If the tooth-on-tooth position is released, the spring force decreases and the transmission element is brought into its coupled position.

[0003] Since most of the components (in particular the spring device, the actuating element, the intermediate element usually arranged between the actuating element and the transmission element and any damping devices and their parts) are usually designed as separate components, the production and assembly of such an actuating device is complicated. Summary of the invention

[0004] The object of the present invention is to provide an actuating device for actuating a transmission element which is improved compared to the prior art and which in particular can be assembled in a less complicated manner.

[0005] This object is achieved by an actuating device having the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0006] As mentioned at the outset, the invention relates to an actuating device for actuating a transmission element, such as a sliding sleeve. The actuating device comprises an actuating element and a spring device, wherein the actuating element is provided for actuating the transmission element. The actuating element can be designed, for example, as a shift fork. The spring device is designed to build up a spring force when a tooth-on-tooth state occurs at the transmission element, i.e., at the toothing of the transmission element relative to the toothing to be coupled, for example, when the toothing of the sliding sleeve is in a tooth-on-tooth state with the toothing of another transmission element, such as a driven gear or a coupling body.

[0007] The invention is based on the recognition that the actuating device has at least one contact element, in particular a switch plate, which is arranged on the actuating element and supported on the actuating element by means of a spring device. The invention therefore proposes to "integrate" the spring device and the contact element into the actuating element. By providing the contact element, it is possible to "compress" the contact element, for example the switch plate, which is supported on the actuating element in a spring-loaded manner by the spring device, when a tooth-on-tooth state occurs.

[0008] In other words, when the operating element is operated, i.e. when the operating element is moved in the direction of the transmission element, the contact element contacts the corresponding contact surface of the transmission element with the first contact surface. The contact element thus realizes the contact between the operating element and the transmission element and moves the transmission element, for example, into its coupled state or coupled position. The movement of the operating element is thus transmitted to the transmission element by the contact element.

[0009] If a tooth-on-tooth condition occurs when the transmission element is moved into its coupled position, the contact element can be moved relative to the operating element in which the contact element is arranged, wherein the spring device is deformed and exerts a spring force between the contact element and the operating element. Once the tooth-on-tooth condition is released, the spring device moves the contact element relative to the operating element in its coupled position so that the transmission element moves into its coupled position. In other words, in the tooth-on-tooth condition, the contact element can be preloaded so that when the tooth-on-tooth condition is released, the transmission element moved by the contact element can "bite" into the corresponding toothing.

[0010] Advantageously, a large number of components do not have to be provided and assembled separately, but the actuating element can be assembled, in particular, as a preassembled assembly. The actuating element can carry the spring device and the contact element as an already preassembled assembly, so that the spring device and the contact element can be assembled together when the actuating device is assembled. To generate the spring force, the spring device can have at least one spring element, for example a helical spring, a spring assembly or any other suitable spring element.

[0011] The described actuating element can have at least one recess with a support section and a seating section, wherein at least one spring element of the spring device is supported in the support section of the recess and the at least one contact element is seated in the seating section of the recess. The seating section and the recess can be designed, for example, to be concentric with each other, for example with respect to an axis of symmetry or an actuation direction of the actuating element. The spring element can in turn be arranged concentrically with a part of the contact element or coaxially around a part of the contact element.

[0012] The support section can be configured, for example, as a depression in the operating element extending in the axial direction. The placement section can also be configured as a depression in the operating element, wherein the placement section can have a smaller diameter than the diameter of the support section. The basic cross-sectional shape of the support section and the placement section can be selected arbitrarily, for example circular. The placement section can extend completely through the operating element in the axial direction in a perforated manner. On the side opposite to the contact element, the contact element can be connected to a docking element, which can determine the maximum separation displacement relative to the operating element. A second contact surface can be provided on the docking element, which is used to contact the transmission element when moving to the separation position.

[0013] The spring element preferably has a defined spring characteristic curve, so that the contact element can basically trigger the movement of the transmission element when it comes into contact with the transmission element, without the spring element being significantly compressed, as long as a tooth-on-tooth condition does not occur. Only when a tooth-on-tooth condition occurs, the spring element is compressed, thereby applying a preload to the contact element, as described above.

[0014] The operating device can define a reference point at which the contact element moves towards the operating element, in particular comes into contact with the operating element, when the spring element is deformed. In other words, for example, in the coupled state of the transmission element, a further movement of the operating element can be carried out, in particular beyond the coupled position in the operating direction, in order to compress the spring element until the contact element comes into contact with the operating element or until the spring element is maximally compressed. This reference point can be used to determine the position of the operating device, for example, in order to actuate an actuator that actuates the operating element. This reference point can be stored, for example, in the control device and checked or updated within the scope of a calibration. Based on this reference point, for example, a coupled position and a decoupled position or a zero point can be defined.

[0015] According to another design of the operating device, a plurality of contact elements, especially distributed in the circumferential direction, can be arranged on the operating element, and / or at least one contact element can be configured as a ring segment. By providing a plurality of contact elements distributed in the circumferential direction or configuring at least one contact element as a ring segment, the operating force of the operating element can be introduced into the transmission element more uniformly via the contact element. This reduces the tipping moment when operating the transmission element and thus improves the operating movement. Here, for example, the contact element can be designed as an annular segment, which extends between the two ends of the operating element designed as a shift fork. The annular segment can be placed at any number of placement sections, for example, at two placement sections, which are opposite to each other in the radial direction relative to the rotation axis of the transmission element or arranged at opposite circumferential positions. Accordingly, the contact element can also be supported by a plurality of spring elements, which are also arranged at the placement section, more precisely, at the support section in the area of ​​the placement section.

[0016] According to another embodiment of the actuating device, it can be provided that the spring device is designed to hold the contact element in the coupling position, in particular by a defined preload. In principle, the preload of the spring device can be adjusted as desired. For this purpose, the entire system, more precisely the entire actuating device or transmission device, can be adapted by the selection or geometry of the at least one spring element, for example, by the configuration as a helical spring, a disc spring, a leaf spring and the respective spring stiffness. For example, stiffnesses in the transmission path or the actuating path can be taken into account here. In addition, the spring stiffness can be selected according to the requirements of the switching time. By providing a defined preload in the coupling position, the contact element can remain prestressed relative to the transmission element and thus hold the transmission element in its coupling position until the actuating element is moved back into the separated state again.

[0017] The operating device may also include a damping device, which has at least one damping element, which is at least partially accommodated in a fluid space constructed in the operating element, the damping element is connected to the at least one contact element and is configured to damp the movement of the contact element, in particular the movement from the tooth-to-tooth state to the coupling position, by displacing the fluid from the fluid space. As mentioned above, the contact element is accommodated in a mounting section in the operating element and is prestressed by the at least one spring element or generally by a spring device when the tooth-to-tooth state occurs. If the tooth-to-tooth state is released, the contact element moves to the coupling position together with the transmission element due to the reduction of the spring energy. In order to prevent collisions that cause acoustic anomalies and can be perceived as interference by the occupants of the motor vehicle during such a movement, a damping device is provided.

[0018] Finally, the damping device is configured to damp the movement of the contact element. To this end, the damping device is connected to the contact element so that when the contact element moves, in particular by elastic force, the contact element is prevented from hitting the operating element or the movement is damped, so that acoustic anomalies can be reduced or prevented. To this end, a fluid space is configured in the operating element, in which the damping element described can be accommodated or at least partially accommodated. For example, a fluid (such as air or oil) present in the field of the operating element can be used as the fluid space. When the spring element is compressed, the fluid space is filled with fluid, wherein, when the elastic force decreases and the contact element withdraws, the fluid is at least partially expelled from the fluid space, and thus the movement of the contact element is damped by the outflow of the fluid, or more precisely, by expelling the fluid from the fluid space. Therefore, due to the relative position of the damping element with respect to the fluid space, the fluid space in the compressed state is larger than the fluid space in the rebound state.

[0019] The fluid space can be understood, for example, as a cylinder in which a damping element constructed as a piston is accommodated. Through the connection between the damping element and the contact element, the movement of the contact element is transmitted to the damping element, which displaces the fluid out of the fluid space by movement and thus damps the movement of the contact element. In order to displace the fluid out of the fluid space, a dedicated opening can be provided, for example, using a retractable or expandable orifice or a throttle valve. A gap portion can also be provided around the fluid space between the damping element and the inner wall of the fluid space, through which the fluid can be displaced and ejected in a defined manner when the damping element moves into the fluid space. The shapes of the damping element and the fluid space should be coordinated with each other, but in principle can be selected arbitrarily, such as circular or rectangular.

[0020] As described, the damping element is connected to the contact element so that the movement of the contact element can be damped or the movement of the contact element can be transmitted to the damping element, so that as described above, the fluid can be displaced from the fluid space so as to damp the movement of the contact element. The operating device can also be configured so that the at least one damping element is connected to the at least one contact element via a through-portion in the operating element, in particular a channel-shaped through-portion. The through-portion described can also be arranged concentrically with respect to the center axis of the contact element, in particular relative to the placement section and the support section described above. In particular, it is provided that the individual components are arranged symmetrically on the operating element. To this end, the contact element, the spring element, the support section, the placement section, the fluid space, the damping element and the through-portion can be symmetrically arranged on the same center axis according to any selection and combination.

[0021] Therefore, the through-portion can connect the two sides of the operating element to each other in the form of a channel. Here, in particular, the placement section can be connected to the fluid space located on the opposite side of the operating element. Here, the contact element and the damping element can be connected in the area of ​​the placement section or in the area of ​​the through-portion. The movement of the contact element is therefore directly converted into the movement of the damping element. For example, the contact element and the damping element can be made of plastic, such as PEEK or PA. At least one of the two parts, i.e. the contact element or the damping element, can also be made of this plastic. Finally, the contact element and the damping element can be connected in any way, such as by snap connection, by threaded connection or other connection methods. In addition, multiple contact elements can be set. In this case, a corresponding number of damping elements can be set. If the contact element extends on the circumferential area on the operating element, for example in the form of an annular segment, multiple damping elements can be connected to the same contact element in the same way.

[0022] At least one damping element can have a second contact surface opposite to the first contact surface of the contact element. The first contact surface of the contact element is used to achieve contact between the contact element and the transmission element. In other words, the contact element contacts the transmission element with the first contact surface in order to move the transmission element into the coupling position. The damping element can have a second contact surface, which is opposite to the first contact surface in the actuation direction. With this second contact surface, for example, a movement of the transmission element into the separation position can be carried out. Therefore, the damping element can also be used as a contact element during the opposite movement and thus establish contact between the actuating element and the transmission element. When carrying out the separation movement, no spring arrangement is required, because no tooth-to-tooth state occurs in this direction, but the transmission element and its toothing are ultimately pulled out of the toothing to be coupled.

[0023] As described, the actuating device, in particular the actuating element, can be designed as a preassembled component. For example, the actuating element, which can be designed in the form of a shift fork, can in this case have, as preassembled components, a spring element of a spring device attached to the actuating element and a contact element. In addition, it can be provided that the damping element can also be mounted on the actuating element together with the contact element and the spring element. This allows the actuating element to be mounted as a preassembled component, for example in a transmission of a motor vehicle, and during assembly, it is not necessary to separately provide and separately assemble the actuating element, the contact element, the spring element, the damping element and, if necessary, intermediate elements that connect the individual components to one another.

[0024] In addition to the actuating device, the invention also relates to a transmission device having an actuating device, the actuating device described above and at least one transmission element, wherein an actuator is configured to move at least one actuating element of the actuating device in order to actuate the transmission element. The described transmission device can be used in various devices, for example in motor vehicles, in particular in passenger cars or trucks, in construction machines, etc. The transmission element can in principle be assigned to any device, for example a disconnect device or a clutch, for example in order to actuate a transmission element configured as a sliding sleeve.

[0025] Furthermore, the invention relates to a motor vehicle comprising the transmission device described above and / or the operating device described above. All advantages, details and features described above with respect to the operating device can be fully transferred to the motor vehicle and the transmission device. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be explained below according to embodiments with reference to the accompanying drawings. These drawings are schematic diagrams and show:

[0027] Figure 1 It is a cut-off part of a transmission device with a control device;

[0028] Figure 2 yes Figure 1 A longitudinal sectional view of an operating device of the operating device in a first state; and

[0029] Figure 3 yes Figure 2 A longitudinal sectional view of the operating device in the second state. DETAILED DESCRIPTION

[0030] Figure 1 A cutout of a transmission device 1, for example for a motor vehicle, is shown, which has an actuating device 2, which is provided for actuating a transmission element 3, for example a sliding sleeve, of the transmission device 1. The actuating device 2 has an actuating device 4, which is provided with an actuating element 5 and a spring device 6. The spring device 6 has at least one spring element 7, which can exert a spring force on a contact element 8, with which the actuating device 4 actuates the transmission element 3 via the actuating element 5. In addition to the contact element 8 shown, the actuating device 2 can also have at least one further contact element 8, which is arranged, for example, at a circumferential position opposite to the axis of rotation. The number and design of the contact elements 8 can be varied as desired, for example, the contact element 8 can be designed to pass through a defined circumferential area, for example, in the shape of a C or a ring segment. In addition, the actuating device 2 has an actuator, not shown in detail, which is designed to move the actuating element 5, for example, which is designed as a shift fork, in the axial direction, i.e. in a direction of rotation. Figures 1 to 3 Move from left to right or right to left.

[0031] exist Figure 1 , Figure 2 In the case shown, the operating element 5 can be moved into the coupling position in order to couple the transmission element 3 with another transmission element to be coupled. Figure 1 The state in can also be understood as a "disengaged position" or "disengaged state". The transmission element 3 is designed, for example, as a sliding sleeve, which has a toothing, for example an internal toothing, which is intended to be coupled with a corresponding toothing of another transmission element. If the operating element 5 is moved to the coupled position, the contact element 8 also moves with the operating element 5. The contact element 8 contacts the transmission element 3 at the first contact surface 16 and moves the transmission element 3 to the coupled position.

[0032] The spring element 7 is designed or selected, in particular with regard to its spring hardness or spring rate, such that no significant compression of the spring element 7 occurs when the transmission element 3 is moved. However, if a tooth-on-tooth situation is formed between the toothing of the transmission element 3 and the toothing to be coupled, the actuating force exceeds a defined threshold value, so that the spring element 7 can be compressed and thus the contact element 8 can be pushed into the actuating element 5, so that the actuating device 4 is moved from Figure 2 The status shown changes to Figure 3The state shown. Advantageously, the actuating element 5 can thus be moved continuously between the disconnected position and the coupled position. This is particularly advantageous for the control of the actuator and the service life of the actuator, since the actuator of the actuating device 2 only has to perform fewer start-up steps during its service life.

[0033] from Figure 2 and Figure 3 It can be seen that the actuating element 5 has a support section 9 in which the spring element 7 is accommodated and at which the spring element 7 supports the contact element 8 relative to the actuating element 5. In addition, the actuating element 5 has a seating section 10 in which the contact element 8 is seated or guided. Figure 2 The situation shown or Figure 2 The first state shown transitions to Figure 3 During the second state shown, the spring element 7 is compressed and the contact element 8 is pushed further into the seating section 10 in the actuating element 5. Here, for example, the surface of the actuating element 5 facing the contact element 8 can limit the maximum distance that the contact element 8 can be pushed in. The movement of the contact element 8 in the axial direction can also be limited by the extension of the seating section 10 in the axial direction.

[0034] Figure 3 The fully compressed state is shown. If the current tooth-to-tooth state is based on Figure 3 If the state shown is released, the spring energy of the spring device 6 can be reduced and the transmission element 3 can be pushed in. Therefore, once the tooth-to-tooth state is released, the toothing of the transmission element 3 can be brought into the toothing to be connected as the spring element 7 is unloaded.

[0035] The illustrated design also allows approaching or checking the reference position of the operating device 2 or the reference point of the operating device 2. Figure 2 In the state shown, for example, after successfully releasing the tooth-to-tooth state, the operating element 5 can be moved further in the operating direction, in particular beyond the coupling position. Figure 2 Start entering Figure 3 The situation shown is one in which the actuating element 5 is in contact with the contact element 8. The reference position can be used, for example, for calibration or checking of a displacement sensor and can be stored or updated in the control device.

[0036] The spring element 7 of the spring device 6 can also be designed or selected so that Figure 2In the case shown, the contact element 8 is preloaded. If the actuating device 2 is in the coupled position, the spring element 7 holds the contact element 8 in the coupled position. Since the contact element 8 (which can also be referred to as a switching plate or can have such a switching plate) is in contact with the transmission element 3, the transmission element 3 is also held in its coupled position. In order to release the coupled position, the actuating element 5 is moved in the opposite actuating direction, i.e. to the right in the figure shown, so as to transfer the transmission element 3 from the coupled position to the decoupled position.

[0037] like Figures 1 to 3 As further shown, the operating device 2 has a damping device 11, which provides a damping element 12. The damping element 12 is also arranged in the operating element 5, that is, in a recess on the side of the operating element 5 opposite the contact element 8. In particular, the damping element 12 is accommodated in a fluid space 13, which is configured as a recess in the operating element 5. Therefore, depending on the operating state, the damping element 12 is more or less accommodated in the fluid space 13.

[0038] The fluid space 13 and the aforementioned mounting section 10 are connected to each other by a particularly channel-shaped through-portion 14. In this embodiment, the support section 9, the mounting section 10, the fluid space 13 and the through-portion 14 are arranged concentrically with respect to the center axis of the contact element 8 or the damping element 12. Other designs are also possible, in which only the individual elements described are arranged on the same axis in any selected and combined manner.

[0039] The contact element 8 and the damping element 12 can be made of any material. For example, at least one of the two components can be made of plastic, such as PEEK or PA. It is also possible that only one of the two parts is made of plastic and the other component is made of metal. The two components are obviously connected to each other, for example, by a screw connection or a snap connection. In principle, the operating device 4 can be provided as a fully assembled component and assembled in the transmission device 1, more precisely, the operating device 2. The operating device 4 can be connected to the actuator and assembled in the transmission device 1, for example.

[0040] The damping device 11 is particularly provided for damping the contact element 8 from Figure 3 The compression position shown is Figure 2 In other words, during the transition from the tooth-to-tooth state to the coupled position, i.e. during the reduction of the spring energy of the spring device 6, the movement of the contact element 8 is suppressed in order to reduce or eliminate acoustic anomalies. Figure 3 The status shown moves to Figure 2 In the state shown, an element of the operating device 4 , for example an abutment of the contact element 8 , could strike the operating element 5 and cause acoustic disturbances.

[0041] The damping device 11 prevents this by displacing at least part of the fluid from the fluid space 13. Figure 3 Move to the position shown Figure 2 In the position shown, the fluid (e.g., air or oil) is forced out of the fluid space 13, for example, via the gap 15 between the fluid space 13 and the damping element 12, so that the movement is braked or inhibited. For example, a limited opening of the fluid space 13 can also be provided by a retractable or expandable orifice or a throttle valve instead of the gap 15 to achieve the desired damping characteristics.

[0042] As described, the contact element 8 moves toward the transmission element 3 to move the transmission element 3 to the coupled position, wherein the contact element 8 contacts the transmission element 3 with the first contact surface 16. In order to move the transmission element 3 from the coupled position back to the decoupled position, the actuating element 5 moves in the opposite direction. Here, the damping element 12 can contact the transmission element 3 via the second contact surface 17 and thus move the transmission element 3 from the coupled position to the decoupled position.

[0043] In the embodiment shown, the damping element 12 therefore takes over the contact with the transmission element 3 during the movement of the transmission element 3 from the coupled position into the decoupled position by contacting the transmission element 3 at the second contact surface 17 .

[0044] As described, for this purpose, the operating element 5 is moved together with the contact element 8 and the damping element 12 in the direction opposite to the operating direction, that is, from left to right in the figure shown. Here, the damping element 12 contacts the transmission element 3 with the second contact surface 17. Therefore, the contact element 8 and the damping element 12 act as a so-called "switching plate" during the movement of the transmission element 3. In the embodiment shown, the contact element 8, the spring element 7 and the damping element 12 are functionally integrated into the operating device 4, in particular, they are directly arranged on the operating element 5. This results in a particularly easy-to-assemble component. Due to the functional integration of the damping element 12, the damping element 12 not only realizes damping but also realizes the operation of the transmission element 3.

[0045] In addition to the damping device 11 shown, the operating device 2 can also be provided with at least one further damping device 11, which is used, for example, for another contact element 8. As described above, the contact element 8 can also be designed in a certain circumferential area, for example, in the form of a ring segment. Here, the contact element 8 can be arranged on at least two arrangement sections 10 and connected to at least two different damping elements 12.

[0046] The transmission device 1 may be part of a motor vehicle, ie a motor vehicle (not shown in detail) may have the transmission device 1, in particular the actuating device 2 having the actuating device 4. All advantages, details and features are transferable to such a motor vehicle.
