Abstract
Description
Technical Field
[0001] The present invention relates to a switching assembly for establishing and releasing a connection between a driven part of a driving part, and a clutch device for establishing and releasing a connection between a driving part and a driven part of a vehicle.
Background Art
[0002] In order to be able to detect the tooth-on-tooth position during the operation (for example, meshing or coupling) of a form-fit clutch (for example, a dog clutch) of a so-called DCU (decoupling unit), a travel distance sensor may be installed on the switching claw in a known manner. This travel distance sensor is required because the actuator that moves the switching claw may already have completely reached the final position of the switching claw where the clutch is normally closed (when establishing frictional connection). In that case, a travel distance sensor on the switching claw requires wiring that is equally important to assemble at the same time as the travel distance sensor.
Summary of the Invention
Problems to be Solved by the Invention
[0003] Based on this background, an object of the present invention is to provide a switching assembly and a clutch device for establishing and releasing a connection between a driving part and a driven part of a vehicle, which reduce assembly costs.
Means for Solving the Problems
[0004] This problem is solved by the features of the independent patent claims. Further advantageous developments are the subject matter of the dependent claims.
[0005] The first aspect of the present invention includes a switching assembly for establishing and releasing a connection between a driven part of a driving part.
[0006] The switching assembly has a switching device for establishing and disengaging the clutch device from the driven device. In this case, the switching device has a sliding component that is displaceable in the engagement direction and the disengagement direction.
[0007] To this end, the switching assembly includes an actuator device for displacing the sliding component. In this case, the actuator device has a position adjustment element that is movable between a first position and a second position. The distance traveled (Weg) between the first position and the second position may be referred to as the position adjustment range (Stellweg).
[0008] Furthermore, the sliding component and the position adjustment element are configured such that the movement of the position adjustment element causes displacement of the sliding component, thereby enabling or disengaging of the connection with the driven part.
[0009] Therefore, the movement of the adjustment element, more specifically, the movement of the adjustment element from its first position to its second position, can move or displace the sliding component in its coupling direction. Conversely, the movement of the adjustment element, more specifically, the movement of the adjustment element from its second position to its first position, can move or displace the sliding component in its release direction.
[0010] Furthermore, in the first state, when the position adjustment element moves from its first position to its second position and / or the switching device is not functioning to establish engagement of the clutch device with the driven device, the sliding component and the position adjustment element are geometrically adjusted and aligned with respect to each other so that the sliding component prevents the position adjustment element from reaching the second position.
[0011] As a result, the actuator device is unable to move the position adjustment element to its second position. In other words, the actuator device is unable to move the position adjustment element to its second position because the engagement of the switching device to the driven device of the clutch device is not functioning or does not allow engagement.
[0012] Furthermore, in a second state in which the position adjustment element moves from its first position to its second position and / or the switching device is permitted to establish engagement of the clutch device with the driven device, the sliding component and the position adjustment element are geometrically adjusted and aligned with respect to each other so that the sliding component can enable the position adjustment element to reach the second position.
[0013] Accordingly, the actuator device can move the position adjustment element to its second position. In other words, the actuator device can move the position adjustment element to its second position by acknowledging or allowing the switching device to engage with the driven device of the clutch device.
[0014] Using this configuration, it is possible to determine whether and / or whether the tooth-on-tooth position or the engagement of the switching device to the driven device of the clutch device is possible or has been achieved by evaluating the electrical quantity in the actuator device. This is because torque can only be transmitted when a connection with the driven part can be established. Otherwise, the connection with the driven part remains disconnected, and thus the connection with the driven part is either not possible or disconnected.
[0015] In this case, the actuator device may have a force sensor and / or a travel distance sensor, and the force sensor and / or the travel distance sensor can be used to detect a force acting along the position adjustment range of the position adjustment element or in the direction of a second position, and / or a travel distance sensed along the position adjustment range of the position adjustment element or in the direction of a second position.
[0016] The actuator device or force sensor may be configured to detect a first force level, which signals the unhindered, free, and / or unblocked movement of the position adjustment element in the direction of a second position.
[0017] Furthermore, the actuator device or force sensor can be configured to detect a second force level, which signals a stop at a certain distance of movement of the position adjustment element in the direction of the second position.
[0018] In that case, the actuator device and / or force sensor and / or travel distance sensor may be configured to interrupt the movement of the position adjustment element in the direction of the second position if a second force level is detected or an insufficient position adjustment range is detected.
[0019] Furthermore, the actuator device and / or force sensor and / or travel distance sensor may be configured to continue moving the position adjustment element in the direction of the second position if a decrease in the direction from the second force level to the first force level is detected, or if a sufficient or operable position adjustment range is detected.
[0020] Therefore, the switching assembly can use an actuator device to detect whether the tooth-on-tooth position or the engagement of the switching device with the driven device of the clutch device is possible and / or has been achieved. Furthermore, compared to the prior art, assembly costs can be reduced because, for example, a travel distance sensor is not required for the switching claw or dog clutch.
[0021] Furthermore, the sliding parts may be integrally constructed.
[0022] Furthermore, the sliding component has a contact portion, and the position adjustment element is movable toward the contact portion, and the position adjustment element can be blocked by the contact portion when it reaches a second position. In this case, the contact portion may have a geometry configured in the shape of an inclined path in order to generate a pressing force in the connecting direction by being added to the sliding component via the position adjustment element.
[0023] Furthermore, the abutting portion may have a chamfered and / or bent at a certain angle and / or fabricated with low friction geometry, so that, for example, the notching portion of the connection portion of the sliding part or the connection portion configured as the first part of the dog clutch (for example, the switching claw) is not prevented in the engagement or establishment of the connection by the axial force of the actuator or the actuator device.
[0024] The abutting portion may be configured in a hollow cylinder shape and / or an inclined path shape.
[0025] In addition, the sliding part may have a connection portion, and using the connection portion, the frictional connection and / or the form connection with the driven part or the driven device of the clutch device can be established or released. The connection portion may be configured in a hollow cylinder shape and / or an annular disk shape.
[0026] In addition, the connection portion may have a notching portion or be configured as the first part of the dog clutch. The notching portion may be configured like that in the case of bevel gears.
[0027] Furthermore, the sliding part may have an intermediate part that mechanically interconnects the connection part and the abutting part. The intermediate part may be configured in a hollow cylinder shape.
[0028] Furthermore, the sliding part may be configured in an L shape or have an L shape when viewed in half. In that case, the shorter leg of the L shape may form the connection portion of the sliding part. The longer leg of the L shape may form the abutting portion of the sliding part and / or the intermediate part of the sliding part.
[0029] In addition, the switching device has a muff component, the muff component is displaceable in the connecting direction and the releasing direction, and is movable relative to the sliding component. The muff component may be disposed relatively displaceably and / or relatively movably on the sliding component. Additionally, the muff component may be configured to be displaced by a switching element of the actuator device. In other words, the muff component may be displaceable by a switching element of the actuator device.
[0030] Furthermore, the muff component may be configured in a hollow cylinder shape and / or may be configured in a U-shape or have a U-shape when looking at half of it.
[0031] In addition, the muff component may have a receiving portion, and for displacing or moving the muff component in the connecting direction and the releasing direction, the switching element of the actuator device fits into the receiving portion.
[0032] Also, the switching device may have a spring element disposed between the muff component of the switching device and the sliding component of the switching device. The spring element may be supported on the muff component on one hand and the connecting portion of the sliding component on the other hand. Also, the spring element may bias the muff component and the sliding component in opposite directions. In that case, the force of the spring element may be greater than the gripping force / frictional force between the sliding component and the position adjusting element, which is generated on the sliding component by the abutment of the position adjusting element or the first end portion of the position adjusting element. Therefore, it may be ensured that when the tooth-on-tooth position is released, for example, as soon as the claws of the dog clutch engage with each other, the switching device or its sliding component can reliably engage with the driven part or the driven device of the clutch device, or can reliably establish a connection.
[0033] Furthermore, the actuator device may have a switching element, and displacement movement can be transmitted to the switching device using the switching element. The switching element may be configured similar to a switching fork. Also, the switching element may be configured in an L-shape or have an L-shape.
[0034] Furthermore, the switching element may be rotatably located at the transition point from one leg to the other, for example, in the housing of a clutch device.
[0035] The first end of the switching element may be movably or rotatably positioned within the housing of the muff component of the switching device.
[0036] Furthermore, the first end of the switching element may have a ball head.
[0037] The second end of the switching element may be movably and / or rotatably connected to the position adjustment element of the actuator device. In this case, the second end of the switching element may have an elongated hole to allow relative rotation and relative displacement of the switching element with respect to the position adjustment element of the actuator device.
[0038] Furthermore, the position adjustment element of the actuator device may be configured as a shaft or as a linearly movable rod.
[0039] In addition, the position adjustment element may have a first end and / or a free end that form a contact portion for the muff component of the switching device in the release direction.
[0040] Furthermore, the position adjustment element may have a first end and / or a free end that can contact the sliding component of the switching device when moving in the direction of the second position in the first state. Also, in combination with the contact portion of the sliding component, the position adjustment element may be restricted in the second direction within its movement path or within its position adjustment range by its first end and / or free end.
[0041] In addition, the position adjustment element may have a second end located inside the actuator device or inside the actuator of the actuator device.
[0042] Furthermore, the actuator device may have a connecting element for connecting a position adjustment element to a switching element of the actuator device. The connecting element may be configured to transmit the linear movement of the position adjustment element to the switching element of the actuator device. Furthermore, the connecting element may be rotatably connected to the switching element of the actuator device.
[0043] A second aspect of the present invention includes a clutch device for establishing and disengaging a connection between a drive unit and a driven unit of a vehicle.
[0044] It should be clearly noted that the features of the switching assembly can be applied to the clutch device, either alone or in combination, as described under the first aspect.
[0045] In other words, with respect to the features described above under the first aspect of the present invention, the switching assembly can also be combined with further features under the second aspect of the present invention as described herein.
[0046] A clutch device for establishing and disengaging the connection between the drive unit and the driven unit of a vehicle has a switching assembly according to a first embodiment. In this case, the switching device of the switching assembly is connectable to the drive unit.
[0047] Furthermore, the clutch device has a driven device that includes a connecting element that can be connected to a driven part.
[0048] The connecting element may have a geared portion or may be configured as a second part of a dog clutch. The geared portion may be configured as in the case of a bevel gear.
[0049] In the first state of the switching assembly, the connecting element and the connecting portion of the sliding part are not interlocked or connected to each other in a friction joint and / or shape joint manner, so that the spring element of the switching device of the switching assembly can be compressed or compressed or reduced by the muff component of the switching device and by the connecting portion of the sliding part of the switching assembly. In this case, the connection between the drive unit and the driven unit of the vehicle may be disengaged or can be disengaged.
[0050] Furthermore, in the first state of the switching assembly, the spring element of the switching device of the switching assembly can be compressed, depressed, or reduced by the muff component of the switching device and by the connecting portion of the sliding component of the switching assembly.
[0051] As a result, the gear teeth of the connecting element and the gear teeth of the connecting portion of the sliding part may be positioned tooth-on-tooth, or they may be at a distance from each other equivalent to the sum of the tip diameters of both gear teeth.
[0052] Alternatively, this may result in a state where force transmission between the connecting element, which is configured as the second part of the dog clutch, and the connecting part of the sliding component of the switching assembly, which is configured as the first part of the dog clutch, is eliminated or impossible. This is because, when the dog clutch is not closed, the first and second parts of the dog clutch are tooth-on-tooth rather than interlocked.
[0053] Furthermore, in the first state, the first end of the position adjustment element is in contact with the sliding component of the switching device, so the sliding component of the switching device prevents the position adjustment element of the actuator device from reaching the second position.
[0054] In the second state of the switching assembly, the extension of the spring element of the switching device of the switching assembly pushes the connection between the muff component of the switching device of the switching assembly and the connection between the sliding component of the switching assembly in opposite directions, so that the connection element and the connection between the sliding component can mesh or connect with each other in a frictional and / or geometric connection manner. In this case, a connection can be established between the drive unit and the driven unit of the vehicle.
[0055] Furthermore, in the second state of the switching assembly, the geared portion of the connecting element and the connecting portion of the sliding part can engage by applying the spring element of the switching device of the switching assembly.
[0056] Alternatively, in the second state of the switching assembly, by applying the spring element of the switching device of the switching assembly, the connecting element formed as the second part of the dog clutch and the connecting part of the sliding component of the switching assembly, which is configured as the first part of the dog clutch, can be engaged, and both can be connected to transmit force.
[0057] Furthermore, in the second state, the sliding component of the switching device may enable the position adjustment element of the actuator device to move toward the second position, so that the sliding component of the switching device allows for a further position adjustment range relative to the first end of the position adjustment element or relative to the position adjustment element by displacement in the release direction.
[0058] In both alternative cases, the spring element of the switching device in the switching assembly can push the muff component of the switching device in the switching assembly and the sliding component of the switching assembly in opposite directions.
[0059] Finally, it should be noted that the clutch device may have a housing to separate it from the outside. In that case, the position adjustment elements of the actuator device may be located in the housing.
[0060] In addition, it should be noted that at least the sliding parts, muff parts, and connecting elements may be rotationally symmetric with respect to the axis of rotation.
[0061] Below, the concept of the present invention described above will be further supplemented and expressed in different terms.
[0062] This idea, in short, relates to a geometry of shape connection (limiting the range of movement) such that while the claw or teeth are in the tooth-on-tooth position, the geometry does not allow movement to a fully moved position (e.g., engaged in the claw) or a second position by the actuator device or the actuator of the actuator device, and only when the claw or teeth are much more fully engaged does the actuator range or position adjustment range become possible.
[0063] Therefore, it is possible to determine how far the actuator or position adjustment element of the actuator device has moved via sensors or force sensors and / or distance sensors located in the actuator of the actuator device. As long as it is impossible for the actuator to move to a fully moved position or a second position (due to limitations in distance travel), this information can be fed back to a higher-level control device (vehicle), for example.
[0064] As a result, information regarding the claw position can be obtained only through sensors or force sensors and / or distance sensors located in the actuator of the actuator device, thereby eliminating the need for additional sensors in, for example, the switching claw or the claw, or in, for example, the first part of the dog clutch.
[0065] The present invention will be described in more detail below based on examples and in relation to the corresponding drawings. [Brief explanation of the drawing]
[0066] [Figure 1]This is a cross-sectional view of a switching assembly for establishing and disconnecting the drive unit from the driven unit. [Figure 2] Figure 1 is a cross-sectional view of the switching assembly in its first state. [Figure 3] Figure 1 is a cross-sectional view of the switching assembly in its second state. [Modes for carrying out the invention]
[0067] In the following explanation, the same reference numeral is used for the same object.
[0068] Figure 1 shows a cross-sectional view of the switching assembly 1 for establishing and disconnecting the drive unit from the driven unit. Figures 2 and 3 show cross-sectional views of the switching assembly in Figure 1, one in the first state (Figure 2) and the other in the second state (Figure 3).
[0069] To keep things concise, Figures 1 through 3 will be explained together below.
[0070] As shown in detail in Figures 1 to 3, the switching assembly 1 for establishing and disengaging the connection between the drive unit and the driven unit includes a switching device 2 for establishing and disengaging the engagement of the clutch device 30 with the driven unit 31. In this case, the switching device 2 has a sliding component 3 that is displaceable in the coupling direction R1 and the disengagement direction R2.
[0071] Furthermore, Figures 1 to 3 show that the switching assembly 1 includes an actuator device 4 for displacing the sliding component 3, and that the actuator device 4 has a position adjustment element 5. The position adjustment element 5 is movable between a first position P1 and a second release position P2. The distance of movement between the first position P1 and the second position P2 is referred to as the position adjustment range.
[0072] As shown in Figures 1 to 3, the sliding component 3 and the position adjustment element 5 are configured such that the movement of the position adjustment element 5 causes displacement of the sliding component 3, thereby enabling or disengaging a connection with the driven part.
[0073] In the first state, when the switching device 2 is not functioning to establish engagement of the clutch device 30 with the driven device 31, the sliding device 3 and the position adjustment element 5 are geometrically adjusted and aligned with each other so that the sliding device 3 prevents the position adjustment element 5 from reaching the second position (see Figure 2).
[0074] As a result, as can be seen in Figure 2, the actuator device 4 is unable to move the position adjustment element 5 to its second position P2 because, more specifically, the engagement of the clutch device 30 with the driven device 31 is not functioning or does not allow engagement.
[0075] In addition, Figures 1 to 3 show that in the second state, which allows the switching device 2 to establish engagement of the clutch device 30 with the driven device 31, the sliding device 3 and the position adjustment element 5 are geometrically adjusted and aligned with respect to each other so that the sliding device 3 can reach the second position (see Figure 3).
[0076] Accordingly, as shown in Figure 3, at this point the actuator device 4 can move the position adjustment element 5 to its second position P2 by, more specifically, by acknowledging or allowing the clutch device 30 to engage with the driven device 31.
[0077] To this end, the actuator device 2 is equipped with a force sensor (not shown) capable of detecting a force acting in the direction of the second position P2.
[0078] The actuator device 2 or force sensor is configured to detect a first force level, which signals the unhindered, free, or unblocked movement of the position adjustment element 5 in the direction of the second position P2 (see Figure 3).
[0079] Furthermore, the actuator device 2 or force sensor is configured to detect a second force level, and the second force level signals a stop for the movement distance of the position adjustment element 5 in the direction of the second position P2 (see Figure 2).
[0080] Additionally, the actuator device 2 is configured to interrupt the movement of the position adjustment element 5 in the direction of the second position P2 when it detects a second force level (see Figure 2).
[0081] In addition, the actuator device 2 is configured to continue moving the position adjustment element 5 in the direction of the second position P2 when it detects a decrease in the direction from the second force level to the first force level (see Figure 1).
[0082] As can be seen in Figures 1 to 3, the sliding part 3 is integrally formed and has a contact portion 6, the position adjustment element 5 is movable toward the contact portion 6 and the position adjustment element 5 can be blocked by the contact portion 6 when it reaches a second position P2. In this case, the contact portion 6 may have a geometric shape configured as an inclined path in order to generate an additional pressing force in the connecting direction R1 to the sliding part 3 via the position adjustment element 5. The contact portion 6 may also have a geometric shape that is chamfered / bent at a certain angle and / or manufactured to have low friction. Furthermore, the contact portion 6 is configured as a hollow cylinder.
[0083] Furthermore, the sliding component 3 includes a connecting portion 7, which enables or disables frictional and / or geometric connections between the clutch device 30 and the driven device 31. The connecting portion 7 is configured in an annular disc shape on one side and as the first part of a dog clutch on the other.
[0084] In addition, the sliding part 3 has an intermediate portion 8 which is configured as a hollow cylinder, and the intermediate portion 8 mechanically connects the connecting portion 7 and the contact portion 6.
[0085] According to Figures 1 to 3, the sliding part 3 is configured in an L-shape when viewed in half, or has an L-shape. The short L-shaped legs form the connecting portion 7 of the sliding part 3, and the long L-shaped legs form the contact portion 6 and the intermediate portion 8 of the sliding part 3.
[0086] Furthermore, as shown in Figures 1 to 3, the switching device 2 has a muff component 9, which is displaceable in the coupling direction R1 and the release direction R2, and is movable relative to the sliding component 3. In other words, the muff component 9 is positioned on the sliding component 3 in a relatively displaceable or relatively movable manner.
[0087] The muffler part 9, when viewed in half, is configured as a hollow cylindrical U-shape or has a U-shape.
[0088] In this case, the muff component 9 has a housing portion 10, and the switching element 12 of the actuator device 4 fits into the housing portion 10 in order to displace or move the muff component 9 in the connecting direction R1 and the release direction R2.
[0089] Furthermore, Figures 1 to 3 show that the switching device 2 has a spring element 11 positioned between the muff component 9 and the sliding component 3. In this case, the spring element 11 is supported on one side by the muff component 9 and on the other side by the connecting portion 7, and the spring element 11 biases the muff component 9 and the sliding component 3 in opposite directions. The force of the spring element 11 is greater than the gripping force / friction force between the sliding component 3 and the position adjustment element 5, which is generated on the sliding component 3 by the contact of the position adjustment element 5 or its first end 15. Therefore, it can be ensured that the switching device 2 or its sliding component 3 can reliably establish a connection between the clutch device 30 and the driven device 31.
[0090] As already explained, the switching device 2 includes a switching element 12 capable of transmitting displacement motion to the switching device 2. In this case, the switching element 12 is configured similarly to a switching fork. In other words, the switching element 12 is configured in an L-shape or has an L-shape.
[0091] In addition, as shown in Figures 1 to 3, the switching element 12 is positioned, for example, in the housing of the clutch device 30 so as to be rotatable from one leg to the other during transmission.
[0092] In this case, the first end 13 of the switching element 12 is movably or rotatably positioned within the housing 10 of the muff component 9, and the first end 13 of the switching element 12 has a ball head. In contrast, the second end 14 of the switching element 12 is movably or rotatably connected to the position adjustment element 5 of the actuator device 4, and the second end 14 has an elongated hole to allow relative rotation and relative displacement of the switching element 12 with respect to the position adjustment element 5.
[0093] As shown in Figures 1 to 3, the position adjustment element 5 of the actuator device 4 is configured as a linearly movable rod and has a first free end 15. This end 15 forms a contact portion for the muff component 9 of the switching device 2 in the release direction R2. In this case, the first free end 15 contacts the sliding component 3 of the switching device 2 when moving in the direction of the second position P2 in the first state (see Figure 2). Furthermore, in combination with the contact portion 6 of the sliding component 3, the position adjustment element 5 can be restricted in the second direction P2 within its movement path or position adjustment range by its first free end 15. Naturally, the position adjustment element 5 has a second end (not shown) located inside the actuator device 4 or inside the actuator of the actuator device 4.
[0094] Furthermore, Figures 1 to 3 show that the actuator device 4 has a connecting element 16 for connecting the position adjustment element 5 to the switching element 12. In this case, the connecting element 16 is configured to transmit the linear movement of the position adjustment element 5 to the switching element 12, and the connecting element 16 is rotatably connected to the switching element 12.
[0095] Furthermore, Figures 1 to 3 show a clutch device 30 for establishing and disengaging the connection between the drive unit and the driven unit of the vehicle.
[0096] The clutch device 30 has the aforementioned switching assembly 1 which can be connected to the drive unit. In addition, the clutch device 30 has a driven device 31 which has a connecting element 32 which can be connected to the driven unit. The connecting element 32 is configured as a second part of the dog clutch.
[0097] In that case, in the first state of the switching assembly 1 in Figure 2, the connecting element 32, which is configured as the second part of the dog clutch, and the connecting portion 7 of the sliding part 3, which is configured as the first part of the dog clutch, are positioned relative to each other in such a way that force transmission between them is impossible. Therefore, the spring element 11 of the switching device 2 is compressed or compressed by the muff part 9 of the switching device 2 and by the connecting portion 7 of the sliding part 3. This is because the first and second parts of the dog clutch are not interlocked but are positioned tooth-on-tooth, and the dog clutch is not closed.
[0098] In other words, Figure 2 shows that in the first state, the first end 15 of the position adjustment element 5 is in contact with the sliding part 3 of the switching device 2, and that when the position adjustment element 5 reaches the second position P2, the sliding part 3 is blocked.
[0099] In the second state of the switching assembly 1 shown in Figure 3, the spring element 11 of the switching device 2 is applied so that the connecting element 32, which is configured as the second part of the dog clutch, and the connecting portion 7 of the sliding part 3, which is configured as the first part of the dog clutch, engage with each other, and both are connected in a way that transmits force. In this case, the spring element 11 of the switching device 2 pushes the muff part 9 of the switching device 2 and the connecting portion 7 of the sliding part 3 in opposite directions.
[0100] Therefore, in the second state, the sliding part 3 of the switching device 2 enables the position adjustment element 5 of the actuator device 4 to move toward the second position P2, so that the sliding part 3 can move toward the second position P2, thereby enabling a further position adjustment range relative to the first end 15 of the position adjustment element 5 or the position adjustment element 5 by displacement toward the release direction R2.
[0101] Finally, it should be noted that at least the sliding component 3, the muff component 9, and the connecting element are rotationally symmetric with respect to the axis of rotation D. [Explanation of Symbols]
