Abstract
Description
Field of the Invention
[0001] The present invention relates to a slave device for a hybrid vehicle or an electric vehicle, such as a concentric slave cylinder, and a drive device for a hybrid vehicle or an electric vehicle. Background Art
[0002] Slave devices, such as concentric slave cylinders, are used in hybrid drives, for example to disconnect an electric motor from an internal combustion engine and to connect the electric motor to the internal combustion engine. Therefore, the perfect function of the slave unit in a transmission, such as in a hybrid transmission, is very important with respect to its functional safety.
[0003] Figure 1 and Figure 2 The slave device 1 shown in Figure 1 shows a piston element 21 in the retracted state, while Figure 2 shows the piston element in the extended state.
[0004] Generally, the piston element 21 can move axially relative to the housing element 2 due to pressure build-up in the pressure chamber D and the feed chamber Z, whereby a clutch device (not shown) of the drive device can be actuated. In this case, the clutch device closes when the piston element 21 disengages (extended state of the piston element 21). Once the clutch device is closed, full torque can be transmitted.
[0005] During pressure reduction, the piston element 21 moves back to the starting position and the clutch device (not shown) disengages. This means that no torque can be transmitted. A disc spring (not shown) presses the piston element 21 back to the retracted state.
[0006] In the extended state (piston element disengaged / pressure build-up - see Figure 2 ), and for example also at high speeds, the tilted position of the slave device 1 can lead to increased power and thus to high pressure pulsations in the pressure chamber D.
[0007] These pressure pulsations lead to an increased load on the housing element 2 and cause the housing element 2 to deform radially inwards (see Figure 2 ). This increases the clearance or distance between the housing element 2 and the housing 51 of the drive device on which the slave device 1 is arranged. This causes the O-ring 16 to be pressed out. This results in damage to the O-ring 16 and leakage occurs. Therefore, the slave device 1 no longer functions. Summary of the Invention
[0008] Against this background, the object of the present invention is to provide a driven device for a hybrid vehicle or an electric vehicle and a drive device for a hybrid vehicle or an electric vehicle, which can be produced at low cost and which solve the above problems or prevent deformation of the housing element of the driven device under increased pressure loads.
[0009] This object is achieved by the features of the independent patent claims. Other advantageous refinements are the subject matter of the dependent claims.
[0010] In a first aspect of the present invention, a driven device for a hybrid vehicle or an electric vehicle, such as a concentric slave cylinder, comprises a housing element having a first housing part and a second housing part, the first housing part and the second housing part being arranged offset from each other in the radial direction. The first housing part may be arranged more radially inwards compared to the second housing part. Furthermore, the housing element may be made in one piece and / or of plastic, which means that the housing element can be manufactured, for example, using an injection molding process.
[0011] Furthermore, the first housing part forms part of a pressure chamber, wherein the complete pressure chamber can be formed by the combination of the first housing part and a piston element of the driven device. This means that the piston element can move axially relative to the housing element due to the pressurized fluid in the pressure chamber.
[0012] In addition, the second housing part forms part of a feed chamber, wherein the complete feed chamber can be formed by the combination of the second housing part and the housing of the drive device which is another part of the feed chamber. The feed chamber and the pressure chamber can be connected to each other in fluid communication such that an increase or decrease in pressure in the feed chamber causes an increase or decrease in pressure in the pressure chamber.
[0013] The second housing part includes a first housing portion in the axial direction, which first housing portion forms the first axial end of the driven device.
[0014] Furthermore, the first housing portion forms a receiving portion for the housing of the drive device, wherein the receiving portion engages around the housing of the drive device such that in the case of a radially inwards directed deformation of the housing element, at least a part of the receiving portion abuts against the housing of the drive device to limit the deformation of the second housing part.
[0015] In addition, the first housing portion or the second housing part may have a radial stop, by means of which a radially inwards directed deformation of the housing element can be limited by a certain amount of deformation of the second housing part.
[0016] The radial stop may be part of the receiving portion or formed by the receiving portion. In other words, the radial stop may correspond to at least one section of the receiving portion.
[0017] When the piston element of the driven device disengages, the inward deformation of the housing element in the radial direction can be caused, for example, by an increased pressure level in the pressure chamber and the feed chamber. Additionally, misalignment of the coupling device during dynamic applications can also result in high-pressure pulsations. Both of these situations can lead to an increased load on the housing element and cause the housing element to deform radially inward, which increases the gap between the housing element and the housing of the drive device. For example, an increase in the gap may cause the seal to move away from its designated position and thus no longer perform its task correctly.
[0018] This radially inward-directed deformation can be counteracted by forming a receiving portion for the housing of the drive device. This is because the receiving portion engages around the housing of the drive device such that the described deformation of the housing element due to the engagement around this configuration results in a stop on the housing of the drive device, whereby the deformation of the second housing part can be restricted.
[0019] Furthermore, the receiving portion can be geometrically complementary to the housing of the drive device. This can improve the stop performance.
[0020] In addition, the receiving portion can be circular and, for example, have an axial cross-section that is shaped like a groove along the axial direction. In this way, the engagement around the housing of the drive device can be easily achieved.
[0021] It can also be provided that the receiving portion is, for example, U-shaped or semi-circular in the axial cross-section along the axial direction, such that a section or a stop region of the housing of the drive device can be accommodated.
[0022] Additionally, the receiving portion can have a first leg, a second leg, and a third leg, which are connected to each other, for example, to form a U-shaped cross-section.
[0023] Furthermore, the first leg and the third leg can be aligned in the same direction, and the second leg can connect the first leg to the third leg. The first leg and / or the third leg can be aligned or oriented in the axial direction.
[0024] The third leg can be designed to be more radially outward than the first leg.
[0025] The third leg of the receiving portion can also form a radial stop that restricts the inward deformation of the driven device in the radial direction.
[0026] It can also be envisaged that the second leg of the receiving portion forms an axial stop. The second leg can be aligned in the radial direction.
[0027] In addition, the second housing part can include a second housing portion.
[0028] The second housing part can be connected to the first housing part of the second housing component in the axial direction. Thus, the second housing part continues the first housing part.
[0029] Furthermore, the second housing part can have a receiving part for a seal which is used to seal the feed chamber in the axial and radial directions. The receiving part can be designed as a groove for receiving the seal.
[0030] Furthermore, it can be provided that the second housing component includes a third housing part.
[0031] The third housing part can be connected to the second housing part of the second housing component in the axial direction. Thus, the third housing part continues the second housing part.
[0032] The third housing part can be combined with the housing of the drive device to form the feed chamber.
[0033] The feed chamber can be limited and sealed by the second housing part and the fourth housing part of the second housing component.
[0034] In addition, the third housing part can have an annular gap which establishes fluid communication between the feed chamber and the pressure chamber. In this way, fluid can flow from the pressure chamber into the feed chamber and fluid can flow from the feed chamber into the pressure chamber.
[0035] The annular gap can form a transition from the pressure chamber to the feed chamber such that pressurized fluid can flow from the feed chamber into the pressure chamber or from the pressure chamber into the feed chamber to move the piston element of the driven device.
[0036] Furthermore, the second housing component can include a fourth housing part.
[0037] The fourth housing part can be connected to the third housing part of the second housing component in the axial direction. Thus, the fourth housing part continues the third housing part.
[0038] Furthermore, the fourth housing part can have a receiving part for a seal which is used to seal the feed chamber in the axial and radial directions. The receiving part can be designed as a groove for receiving the seal.
[0039] In addition, the fourth housing part can form the second axial end of the driven device.
[0040] The first housing part and / or the second housing part and / or the third housing part and / or the fourth housing part of the second housing component can be arranged one behind the other or after another in the axial direction.
[0041] In addition, the driven device may include a piston element that forms a pressure chamber through the combination of the first housing component, such that the piston element can move in the axial direction. More specifically, when the fluid is pressurized in the feed chamber and / or in the pressure chamber, the piston element can be switched from the retracted state to the extended state. By reducing the pressure level in the feed chamber and / or the pressure chamber, the piston element can move back from the extended state to the retracted state. The piston element can be designed as an annular piston.
[0042] The piston element may further include an inner ring seal and an outer ring seal for abutting against the housing element or the first housing component of the housing element.
[0043] The second aspect of the present invention includes a drive device for an electric vehicle or a hybrid vehicle.
[0044] Explicitly referring to the following fact: The features of the driven device as mentioned under the first aspect can be applied to the drive device individually or in combination with each other.
[0045] In other words, the features related to the driven device as mentioned above under the first aspect of the present invention can also be combined with other features under the second aspect of the present invention.
[0046] Therefore, the drive device for a hybrid vehicle or an electric vehicle includes a driven device according to the first aspect.
[0047] In addition, the drive device includes a housing for accommodating the driven device and for forming a feed chamber through combination with the driven device, wherein the housing element of the driven device is arranged on the housing. More specifically, the housing of the drive device and the housing element of the driven device together can form a feed chamber.
[0048] Furthermore, the housing of the drive device can be adapted to the housing element of the driven device such that the receiving portion of the driven device and the housing of the drive device match in terms of their shapes.
[0049] The radial stop of the driven device can be assigned to the section or the stop region of the same orientation of the housing of the drive device. Therefore, the housing of the drive device can form a stop region that is spaced apart from the radial stop of the housing element of the driven device and is adapted to the radial stop of the driven device in terms of the size and shape of the stop region. In other words, the stop region and the radial stop can be matched to be geometrically complementary to each other.
[0050] The stop region and the radial stop have geometries that optimally support the transfer of force from the radial stop to the stop region. In this way, the stop region and the radial stop can each form a surface for contacting the opposite side, and these surfaces are aligned in the same direction or oriented parallel to each other.
[0051] The distance or clearance in the radial direction between the stop region and the radial stop can be a deformation amount that allows the first housing part of the housing element to deform before contacting the stop region of the drive device and the radial stop of the driven device.
[0052] Furthermore, the drive device can include bearing means for supporting the housing on the input shaft or the output shaft.
[0053] The drive device can also have an input shaft for transmitting the torque from the rotating machine. The input shaft can be designed as a hollow shaft.
[0054] In addition, the drive device can have an output shaft for transmitting the torque to the transmission. The output shaft can be designed as a solid shaft.
[0055] Furthermore, the drive device can include a clutch device having an inner multi-disc element and an outer multi-disc element. The clutch device can interrupt or generate a torque flow between the inner multi-disc element and the outer multi-disc element.
[0056] The inner multi-disc element can be connected to the output shaft, and the outer multi-disc element can be connected to the input shaft. This allows the torque to be transmitted from the input shaft to the output shaft.
[0057] Furthermore, the drive device can include a release bearing for enabling or disabling the clutch device, whereby the clutch device or the entire drive device transmits the torque or interrupts the transmission.
[0058] The release bearing can rest against the piston element of the driven device. This means that the release bearing can be actuated directly by the piston element.
[0059] In addition, the drive device can have an intermediate element for transmitting the force from the release bearing to the clutch device. This allows the force of the piston element to be advantageously introduced into the clutch device.
[0060] The drive device can also have a disc spring for resetting the release bearing and thus the piston element of the driven device.
[0061] Hereinafter, the concept of the present invention described above is expressed again and in other words in a supplementary manner.
[0062] This concept, in simplified form, relates to the fact that after the driven device is mounted on the housing of the drive device, the driven device and the housing form a form-fit that prevents the housing element of the driven device from deforming under load.

[0068] Figure 5 Shows a drive device having Figure 3 A cross-sectional view of the driven device. Detailed Description
[0069] In the following description, the same reference numerals are used for the same components.
[0070] Regarding Figure 1 And Figure 2 , referring to the explanations at the beginning of the specification, no further explanation is required at this point.
[0071] Figure 3 Shows a cross-sectional view of the driven device 1 located on the housing 51 of the drive device 50, while Figure 4 Shows Figure 3 A cross-sectional view of the driven device 1 without the housing 51 of the drive device 50.
[0072] For simplicity and brevity, the following describes Figures 3 to 4 .
[0073] Figure 3 And Figure 4 Show a driven device 1 for a hybrid vehicle or an electric vehicle, such as a concentric driven cylinder.
[0074] The driven device 1 has a housing element 2, which has a first housing part 3 and a second housing part 4. The first housing part and the second housing part are arranged to be offset from each other in the radial direction R. The first housing part 3 is arranged more inward in the radial direction R than the second housing part 4. The housing element 2 is a single piece and is made of plastic.
[0075] The first housing part 3 forms part of a pressure chamber D, wherein the complete pressure chamber D can be formed by the combination of the first housing part 3 and the piston element 21 of the driven device 1. This means that the piston element 21 can move relative to the housing element 2 in the axial direction A due to the pressurized fluid.
[0076] Furthermore, the second housing part 4 forms part of the feed chamber Z, wherein the complete feed chamber Z can be formed by the combination of the second housing part 4 and the housing 51 of the drive device 50 which is another part of the feed chamber Z. The feed chamber Z and the pressure chamber D are in fluid communication with each other such that an increase or decrease in the pressure in the feed chamber Z causes an increase or decrease in the pressure in the pressure chamber D.
[0077] The second housing part 4 has a first housing portion 6 in the axial direction A, and this first housing portion forms the first axial end 10 of the slave device 1 (see Figure 4 ).
[0078] Furthermore, the first housing portion 6 forms a receiving portion 11 for the housing 51 of the drive device 50. In this case, the receiving portion 11 engages around the housing 51 of the drive device 50 such that in the case of a radially inwardly directed deformation of the housing element 2, at least a part of the receiving portion 11 abuts against the housing 51 of the drive device 50 to limit the deformation of the second housing part 4.
[0079] Furthermore, as Figure 3 and Figure 4 can be seen, the first housing portion 6 or the second housing part 4 has a radial stop 5 by which the radially inwardly directed deformation of the housing element 2 can be limited by a certain amount of deformation of the second housing part 4. However, the deformation can actually only be limited when the slave device 1 is arranged on the housing 51 of the drive device 50.
[0080] The radial stop 5 is part of the receiving portion 11 or is formed by the receiving portion 11. In other words, the radial stop 5 corresponds to at least one section of the receiving portion 11. Here, the receiving portion 11 is geometrically complementary to the housing 51 of the drive device 50.
[0081] Furthermore, the receiving portion 11 is U-shaped in the axial cross-section such that a section or a stop region 61 of the housing 51 of the drive device 50 can be accommodated.
[0082] The receiving portion 11 has a first leg 12, a second leg 13 and a third leg 14, and the first leg, the second leg and the third leg are connected to each other to form a U-shaped cross-section. The first leg 12 and the third leg 14 are aligned with each other in the same direction and are aligned in the axial direction A. The second leg 13 connects the first leg 12 and the third leg 14, wherein the second leg 13 is aligned in the radial direction R.
[0083] Furthermore, with regard to Figure 4, the third leg portion 14 is formed to be more radially outward than the first leg portion 12, wherein the third leg portion 14 of the receiving portion 11 forms a radial stop portion 5 that restricts the inward deformation of the driven device 1 in the radial direction R. The second leg portion 13 of the receiving portion 11 forms an axial stop portion.
[0084] In addition, Figure 3 and Figure 4 it is shown that the second housing member 4 has a second housing portion 7, wherein the second housing portion 7 abuts the first housing portion 6 of the second housing member 4 in the axial direction A.
[0085] Furthermore, the second housing portion 7 has a receiving portion 15 for a seal 16 that is used to seal the feed chamber Z in the axial direction A and the radial direction R. The receiving portion 15 is designed as a groove.
[0086] In addition, Figure 3 and Figure 4 it is shown that the second housing member 4 includes a third housing portion 8, wherein the third housing portion 8 abuts the second housing portion 7 in the axial direction A.
[0087] The third housing portion 8 and the housing 51 of the drive device 50 form a feed chamber Z, which is restricted and sealed by the second housing portion 7 and the fourth housing portion 9 of the second housing member 4.
[0088] In addition, the third housing portion 8 has an annular gap 17 that establishes fluid communication between the feed chamber Z and the pressure chamber D.
[0089] The annular gap 17 forms a transition from the pressure chamber D to the feed chamber Z such that pressurized fluid can flow from the feed chamber Z into the pressure chamber D or from the pressure chamber D into the feed chamber Z to move the piston element 21 of the driven device 1.
[0090] Figure 3 and Figure 4 It is also shown that the second housing member 4 includes a fourth housing portion 9 that abuts the third housing portion 8 in the axial direction A.
[0091] Here, the fourth housing portion 9 has a receiving portion 18 for a seal 19 that is used to seal the feed chamber Z in the axial direction A and the radial direction R. The receiving portion 18 is designed as a groove.
[0092] The fourth housing portion 9 forms the second axial end 20 of the driven device 1.
[0093] Briefly summarizing the housing parts 6, 7, 8, 9 of the housing element 2, it can be said that the first housing part 6, the second housing part 7, the third housing part 8, and the fourth housing part 9 are arranged one behind the other or after one another in the axial direction A.
[0094] As already indicated, the slave device 1 has a piston element 21 which, in combination with the first housing part 3 of the housing element 2, forms a pressure chamber D such that the piston element 21 can move in the axial direction A. More specifically, when the fluid is pressurized in the feed chamber Z and the pressure chamber D, the piston element 21 can be switched from the retracted state to the extended state. By reducing the pressure levels in the feed chamber Z and the pressure chamber D, the piston element 21 can move back from the extended state to the retracted state.
[0095] The piston element 21 is designed as an annular piston element, wherein the piston element 21 includes an inner ring seal 22 and an outer ring seal 23 for resting against the housing element 2 or the first housing part 3 of the housing element.
[0096] Figure 5 Shows a cross-sectional view of the drive device 50 of the slave device 1 having Figure 3 and Figure 4 of.
[0097] More specifically described, the drive device 50 for a hybrid vehicle or an electric vehicle has the slave device 1 described above and a housing 51 which is used to accommodate the slave device 1 and which, in combination with the slave device 1 or the second housing part 4 of the slave device, forms a feed chamber Z. The housing element 2 of the slave device 1 is arranged on the housing 51.
[0098] Furthermore, according to Figure 5 , the housing 51 of the drive device 50 is adapted to the housing element 2 of the slave device 1 such that the shape of the receiving part 11 of the slave device 1 and the shape of the housing 51 of the drive device 50 match each other in their shape. The radial stop 5 of the slave device 1 is opposite to a stop region 61 of the housing 51 of the drive device 50 which is oriented in the same direction.
[0099] In other words, the housing 51 of the drive device 50 forms a stop region 61 which is spaced apart from the radial stop 5 of the housing element 2 and which is adapted in its dimensions and shape to the radial stop 5. In other words, the stop region 61 of the drive device 50 and the radial stop 5 of the slave device 1 are matched to be geometrically complementary to each other.
[0100] The stop region 61 and the radial stop 5 have geometries which optimally support the transfer of force from the radial stop 5 to the stop region 61. Therefore, the stop region 61 and the radial stop 5 each have surfaces for mutual contact which are aligned in the same orientation with each other or are parallel to each other.
[0101] The distance or clearance between the stop region 61 and the radial stop 5 in the radial direction R is the amount by which the first housing part 6 of the housing element 2 or the housing element 2 can deform before the stop region 61 and the radial stop 5 come into contact.
[0102] In addition, Figure 5 it is shown that the drive device 50 has a bearing device 52 for supporting the housing 51 on the input shaft 53 and an input shaft 53 for transmitting the torque from a turning machine (not shown). The input shaft 53 is designed as a hollow shaft.
[0103] In addition, according to Figure 5 , the drive device 50 has an output shaft 54 for transmitting the torque to the transmission, wherein the output shaft 54 is designed as a solid shaft.
[0104] In addition, it can be seen from Figure 5 that the drive device 50 includes a clutch device 55 having an inner multi-disc element 56 and an outer multi-disc element 57, wherein the inner multi-disc element 56 is connected to the output shaft 54 and the outer multi-disc element 57 is connected to the input shaft 53.
[0105] The drive device 50 also has a release bearing 58 for enabling or disabling the clutch device 55, whereby the clutch device 55 transmits the torque or interrupts the transmission of the torque. The release bearing 58 abuts against the piston element 21 of the slave device 1. Thus, the release bearing 58 can be actuated directly by the piston element 21.
[0106] Furthermore, according to Figure 5 , the drive device 50 has an intermediate element 59 for transmitting the force of the release bearing 58 to the clutch device 55 and a disc spring 60 for resetting the release bearing 58 and thus the piston element 21 of the slave device 1.
[0107] This is described again below Figures 3 to 5 , but in other words.
[0108] The CSC housing or the housing element 2 of the slave device 1 and the housing 51 of the drive device 50 are optimized. This is for the following effect: a form-fit is created between the slave device 1 and the housing 51 of the drive device 50 after the assembly of the slave device 1.
[0109] The collar or the first housing part 6 of the housing element 2 extends for this purpose. This optimization enables the CSC housing / housing element 2 to engage in the housing 51 of the drive device 50 (form-fit) and support itself.
[0110] In order for the CSC housing / housing element 2 of the slave device 1 to be engaged in the housing 51 of the drive device 50, the housing 51 of the drive device 50 is also adapted, i.e., has a suitable recess or a suitable stop area 61. This means that the housing element 2 of the slave device 1 can only be deformed to a certain extent under increased loads.
