Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the application. In the present application, unless otherwise indicated, terms of orientation such as "upper", "lower", "left" and "right" are generally used to refer to the directions of the upper, lower, left and right sides of the device in actual use or operation, and are specifically shown in the drawings.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.
The present application provides a hybrid module, which will be described in detail below. It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.
As shown in fig. 1, in the present application, "axial direction a", "radial direction R", and "circumferential direction" relate to the central rotation axis L of the hybrid module 1. Where "axial direction a" means a direction along the rotation axis L, "radial direction R" means a direction perpendicular to the rotation axis L and "circumferential direction" means a direction along a circumferential line extending concentrically around the rotation axis L.
More specifically, "axial one side" refers to the left side in fig. 1, "axial other side" refers to the right side in fig. 1, "radial outer side" refers to the upper side in fig. 1 (i.e., the side away from the central axis L), and "radial inner side" refers to the lower side in fig. 1 (i.e., the side closer to the central axis L).
As shown in fig. 1, the present application provides a hybrid module 1, the hybrid module 1 having an axial direction a, a radial direction R, and a circumferential direction. The hybrid module 1 includes an electric motor 200 and a dual clutch module 100. The motor 200 includes a stator 210 and a rotor 220 located radially inward of the stator 210 and rotatable with respect to the stator 210. The dual clutch module 100 includes a rotor support 10, a dual clutch 20, and a hydraulic steering system 30. The rotor support 10 is located at a radial inner side of the rotor 220 and is fixedly connected with the rotor 220, and an accommodating space 101 is defined at the radial inner side of the rotor support 10. The double clutch 20 is provided in the housing space 101 and has a first clutch 21 and a second clutch 22 arranged in the radial direction R. The hydraulic steering system 30 is provided in the housing space 101 and has a plurality of disc-shaped members 31 and an oil supply member 32. The plurality of disc members 31 are arranged on the same axial side of the double clutch 20 in the axial direction a, and the plurality of disc members 31 constitute two hydraulic chambers 301 corresponding to the first clutch 21 and the second clutch 22, respectively. The oil supply member 32 is supported on the radially inner side of the plurality of disc members 31 in a manner coaxially disposed with the double clutch 20, and is fluidly connected to each of the hydraulic chambers 301 for selectively supplying a hydraulic medium to each of the hydraulic chambers 301.
In the radial direction R, the hydraulic actuation system 30 and the double clutch 20 are located radially inside the rotor support 10; in the axial direction a, the axial extension of the rotor support 10 substantially overlaps the sum of the axial extensions of both the hydraulic actuating system 30 and the double clutch 20. In short, the hydraulic actuation system 30 can be integrated in the receiving space 101. The axial space required by the hybrid power module 1 is remarkably reduced, which brings convenience to the layout of the automobile and can improve the carrying performance of the hybrid power module 1. In particular, the hybrid module 1 can solve the problem of difficulty in installation due to a small engine compartment.
Specifically, the hybrid module 1 of the present application may be a P1 hybrid module.
As shown in fig. 1, one axial end of the rotor bracket 10 is used to connect with an engine. While the radially outer side of the other axial end of the rotor support 10 is used for carrying the rotor 220 of the motor 200, while the radially inner side of the other axial end of the rotor support 10 defines the accommodation space 101. The rotor support 10 is used to introduce the power of the engine and/or the electric machine 200 into the entire hybrid module 1. In this way, the degree of integration of the hybrid module 1 can be increased, facilitating the reduction of the size of the above hybrid module 1.
Illustratively, the rotor support 10 is generally stepped in shape as viewed in axial cross-section. The rotating shaft bracket 10 includes a flange portion 11, a supporting portion 12, and a connecting portion 13. The flange portion 11 extends in the radial direction R. The connection portion 13 is formed at a radially inner end of the flange portion 11 and extends from the radially inner end of the flange portion 11 toward one axial side. And the support portion 12 is formed at the radially outer end of the flange portion 11 and extends from the radially outer end of the flange portion 11 toward the other side in the axial direction. The connecting portion 13 is for connecting an engine, and for example, the connecting portion 13 may be connected to an engine output shaft by means of a damper. The outer peripheral surface of the supporting portion 12 is used for receiving or mounting the rotor 220 of the motor 200, and the inner peripheral surface of the supporting portion 12 and the flange portion 11 form the receiving space 101.
Further, the flange 11, the support 12 and the connection 13 are integrally provided. The integrated arrangement means that the connection portion 13, the flange portion 11, and the support portion 12 are integrally formed by punching, stretching, bending, or other manufacturing processes. More specifically, the rotor support 10 is an integrally formed member. It should also be noted that the specific implementation of the rotor support 10 of the present application is not limited thereto. For example, in other embodiments, the rotor support 10 may be a split structure.
As shown in fig. 1, the dual clutch 20 further includes a first output hub 23 and a second output hub 24. Wherein the first output hub 23 corresponds to the first clutch 21 and the second output hub 24 corresponds to the second clutch 22. The first clutch 21 is used to connect or disconnect torque transmission between the rotor support 10 and the first output hub 23. The second clutch 22 is used to connect or disconnect torque transmission between the first clutch 21 and the second output hub 24.
Based on the above embodiment, the hybrid module 1 further includes an engine and a transmission. The engine is connected to the rotor support 10 in a rotationally fixed manner, and the transmission comprises a first input shaft connected to the first output hub 23 in a rotationally fixed manner and a second input shaft connected to the second output hub 24 in a rotationally fixed manner. At this time, for the entire hybrid module 1: the rotor support 10 is connected to both the engine and the motor 200 power sources in a rotationally fixed manner. The first clutch 21 is used to connect or disconnect the torque transmission between the rotor carrier 10 and the first input shaft of the transmission, i.e. the engine and/or the electric machine 200 is coupled to or decoupled from the first input shaft of the transmission by means of the first clutch 21. The second clutch 22 is used to connect or disconnect the torque transmission between the first clutch 21 and the second input shaft of the transmission, i.e. the engine and/or the electric machine 200 is coupled to or decoupled from the second input shaft of the transmission by means of the first clutch 21 and the second clutch 22.
The second clutch 22 is located radially inward of the first clutch 21 as viewed in the radial direction R. The axial extension of both the first clutch 21 and the second clutch 22, seen in the axial direction a, substantially overlap. In this way, the overall axial dimensions of the double clutch 20 can be reduced in order to arrange the hydraulic operating system 30 in said housing space 101.
Specifically, the first output hub 23 and the second output hub 24 are arranged along the axial direction a and are located in the accommodating space 101. Further, the second output hub 24 is sleeved on the other axial end of the first output hub 23.
With continued reference to fig. 1, the first clutch 21 and the second clutch 22 each include a pressure plate 201 and a friction plate 202.
Further, the dual clutch 20 further includes a first bracket 25 and a second bracket 26 to facilitate mounting of the pressure plate 201 and the friction plate 202. The first bracket 25 is L-shaped overall, and the radially inner end of the first bracket 25 is mounted on the periphery of the first output hub 23 in a torsion-proof manner. The second support 26 is generally L-shaped, and the radially inner end of the second support 26 is mounted on the periphery of the second output hub 24 in a torsion-proof manner. Preferably, both the first support 25 and the first output hub 23 are integrally formed. Thus, the number of components of the entire hybrid module 1 can be reduced.
Based on the above embodiment, in the first clutch 21: the pressure plate 201 is disposed radially inward of the support portion 12 of the rotor holder 10, and the friction plate 202 is mounted on the first holder 25. In the second clutch 22: the pressure plate 201 is disposed on the first bracket 25, and the friction plate 202 is mounted on the second bracket 26. In other embodiments, the positions of the pressure plate 201 and the friction plate 202 may be interchanged.
Referring to fig. 1, the plurality of disc members 31 are further formed with two balance cavities 302 corresponding to the first clutch 21 and the second clutch 22, respectively. The first clutch 21 and the second clutch 22 have an operating piston 203 located in the hydraulic chamber 301 and a return spring 204 located in the balance chamber 302, respectively. The operation piston 203 is supported on the outer periphery of the oil supply member 32 so as to be axially movable with respect to the oil supply member 32, and the return springs 204 are respectively abutted against the operation piston 203 so as to be axially spaced apart. By constructing the hydraulic chamber 301 and the balance chamber 302 with the plurality of disc members 31, the structure of the hydraulic operating system 30 can be simplified, the axial dimension of the hydraulic operating system 30 can be reduced, the torque transmission path can be simplified, and the torque transmission efficiency can be improved. Furthermore, the oil supply member 32 is disposed radially inside the operating piston 203 to supply the hydraulic medium to the hydraulic chamber 301, so that the oil path is simplified, the size of the hydraulic operating system 30 is reduced, and the cost is reduced.
More specifically, in the hydraulic operating system 30, the plurality of disc members 31 define two cavities. The two cavities are arranged adjacent to one side of the double clutch 20 in the axial direction a and serve to construct hydraulic chambers 301 corresponding to the first clutch 21 and the second clutch 22, respectively. And an oil supply member 32 for supplying a hydraulic medium is located radially inside the two cavities, and the oil supply member 32 extends in the axial direction a and is fitted over the other axial end of the second output hub 24 remote from the first output hub 23.
Since the hydraulic operating system 30 operates the first clutch 21 and the second clutch 22 substantially identically. Hereinafter, the specific embodiment and the working principle of the hydraulic operating system 30 will be specifically described by taking the operation of the first clutch 21 by the hydraulic operating system 30 as an example.
In the first clutch 21, an operation piston 203 is disposed in a cavity corresponding to the first clutch 21 and is supported on the outer periphery of the oil supply member 32 so as to be axially movable with respect to the oil supply member 32, so as to divide the cavity into a balance chamber 302 and the hydraulic pressure chamber 301. The hydraulic chamber 301 is fluidly connected to the oil supply member 32 to move the operating piston 203 by a hydraulic medium, and the return spring 204 is disposed in the balance chamber 302 to provide a return force to the operating piston 203.
More specifically, the operating piston 203 is capable of moving axially from an initial position against the action of the return spring 204 under the driving action of the hydraulic medium in the hydraulic chamber 301, so as to engage the pressure plate 201 and the friction plate 202, and thus engage the first clutch 21. In the case of withdrawal of the hydraulic medium in the hydraulic chamber 301, the return spring 204 can drive the operating piston 203 back to the initial position, so that the pressure plate 201 is separated from the friction plate 202, and the first clutch 21 is disconnected.
Further, the above-described two balance chambers 302 are respectively configured as seal chambers. And, two of the balance chambers 302 are respectively fluidly connected to the oil supply member 32, and the oil supply member 32 is capable of selectively supplying a hydraulic medium to each of the balance chambers 302. Continuing with the specific description of the operation of the first clutch 21 by way of the hydraulic operating system 30, the balance chamber 302 is configured to receive the hydraulic medium of the oil supply member 32 to drive the operation piston 203 to return. More specifically, when the return spring 204 urges the operating piston 203 to return, the balance chamber 302 receives the hydraulic medium and applies a force to the operating piston 203 that urges the operating piston 203 to return, thereby assisting in the return spring 204 to quickly return, and thus the first clutch 21 to quickly release.
Illustratively, the plurality of disc members 31 includes a first disc member 311, a second disc member 312 and a third disc member 313 that are sequentially spaced apart in an axial direction adjacent to the dual clutch 20. The first disc member 311 and the second disc member 312 constitute a cavity corresponding to the first clutch 21, and the second disc member 312 and the third disc member 313 constitute a cavity corresponding to the second clutch 22.
Further, the first disk member 311 is configured as an end cap of the rotor holder 10. More specifically, the housing space 101 has an opening facing the other side in the axial direction, and the first disk member 311 is mounted on the radially inner side of the rotor frame 10 so as to cover the opening, thereby isolating the housing space 101 from the outside. Specifically, the radially inner sides of the first disc member 311, the second disc member 312, and the third disc member 313 are respectively mounted on the outer peripheral surface of the oil supply member 32 in a sealing manner by press-fitting or plugging. Meanwhile, a seal is provided on the radially outer side of each disk member to achieve a sealing connection with the corresponding operating piston 203, ensuring a sealing effect of the balance chamber 302 and the hydraulic chamber 301, preventing leakage of the hydraulic medium. At this time, a seal ring may be provided on the outer peripheral surface of the oil supply member 32, and dynamic sealing of both the operation piston 203 and the oil supply member 32 may be achieved by the seal ring. In particular embodiments, the first disc member 311, the second disc member 312, and the third disc member 313 are rigid members. In this way, the strength of the plurality of disc-like members can be ensured to prevent the operations of the first clutch 21 and the second clutch 22 from interfering with each other.
Illustratively, the oil supply member 32 is implemented in the form of an oil supply pipe. More specifically, the oil supply member 32 is integrally a hollow sleeve member extending in the axial direction a. The oil supply means 32 is formed with a plurality of independent oil supply lines for supplying the hydraulic medium to the hydraulic chamber 301 and/or the balance chamber 302. Preferably, a plurality of the oil supply lines extend in the axial direction of the oil supply member 32, respectively, and are arranged at intervals in the circumferential direction of the oil supply member 32.
As shown in fig. 1, the hybrid module 1 further includes a housing 300 and a resolver 400.
Illustratively, the housing 300 is generally L-shaped as viewed in the axial direction A. The housing 300 includes an axial section 310 extending in an axial direction a and a radial section 320 extending in a radial direction R. The axial section 310 is located radially outward of the support 12, and the axial section 310 and the support 12 have a radial spacing 3001 along the radial direction R. The radial outer side of the radial section 320 is connected with one axial side of the axial section 310 in a torsion-proof manner, the radial inner side of the radial section 320 is mounted on the periphery of the connecting part 13 of the rotor holder 10 in a torsion-proof manner, and the radial section 320 and the flange part 11 have an axial spacing 3002 in the axial direction.
Wherein the radially inner side of the radial section 320 is mounted by means of bearings at the periphery of the connection 13 of the rotor support 10. Further, a locking nut is disposed on the outer periphery of the connecting portion 13, and a limiting member is disposed on the radially inner side of the radial section 320. The locking nut and the limiting piece jointly limit the bearing axially so as to prevent the bearing from axially moving. The radial space 3001 is used for arranging the motor 200. The stator 210 is mounted radially inward of the axial section 310, and the rotor 220 is mounted radially outward of the support 12 of the rotor bracket 10.
As shown in fig. 1, the resolver 400 is mounted in the axial space 3002 for detecting the angular position of the rotor support 10. By disposing the resolver 400 on one axial side of the motor 200 closer to the engine, accuracy of angle detection can be improved.
The resolver 400 includes a resolver stator 410 and a resolver 420 located radially outward of the resolver stator 410 and rotatable relative to the resolver stator 410. Wherein the rotary stator 410 is connected to the side of the radial section 320 facing the rotor carrier 10 in a rotationally fixed manner, and the rotary rotor 420 is connected to the side of the rotor carrier 10 facing the housing 300 in a rotationally fixed manner.
The axial extension of the spin-on stator 410 at least partially overlaps the axial extension of the spin-on rotor 420 as viewed in the axial direction a. With this arrangement, the axial dimension of the resolver 400 can be reduced to further reduce the axial dimension of the hybrid module.
