Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically to a hybrid drive shifting system and a vehicle including the hybrid drive shifting system. Background Art

[0002] With the application of new energy power in vehicles, hybrid vehicles are becoming increasingly popular. Hybrid power systems include at least an engine and a drive motor. The switching and coupling of power is usually achieved through multiple clutches and clutch straight mechanisms, which leads to an increase in the number of components in the shifting system, a more complex structure, which is not conducive to cost savings and also occupies more space, increasing the difficulty of vehicle layout. Summary of the Invention

[0003] In view of this, this application aims to provide a simple gear shifting system that does not require the use of a clutch to switch the power type and gear of hybrid power. While having multiple gear modes, the structure of the gear shifting system is simplified, which helps to reduce costs and improve the convenience of vehicle installation.

[0004] This application mainly provides a hybrid drive shifting system, including:

[0005] The engine drives the shaft to be connected to the first shaft. The first shaft is fitted with a first gear, which is used to connect to the power terminal shaft for transmission.

[0006] A drive motor drives a rotating shaft connected to a second shaft. The second shaft is connected to the power terminal shaft via a gear set. The gear set includes a second gear loosely fitted on the second shaft or the power terminal shaft.

[0007] The first shift fork mechanism includes a first shift fork slide assembly having a first shift fork and a first slide sleeve, and a second shift fork slide assembly having a second shift fork and a second slide sleeve. The first shift fork is used to drive the first slide sleeve to move so that the first slide sleeve engages or disengages with the first gear, and the second shift fork is used to drive the second slide sleeve to move so that the second slide sleeve engages or disengages with the second gear, thereby forming three gear modes: the engine outputs power, the drive motor outputs power, and the engine and drive motor jointly output power.

[0008] In one possible implementation, the first shift fork mechanism further includes a first shift fork shaft and a first shift block slidably sleeved on the first shift fork shaft. The first shift fork and the second shift fork are both slidably sleeved on the first shift fork shaft and both are fixedly connected to the first shift block.

[0009] The first shift block drives the first shift fork and the second shift fork to move synchronously and form three positions corresponding to the three gear modes by being driven by the shift lever or the first drive mechanism.

[0010] In one possible implementation, a generator is also included, with a third gear mounted on the generator's shaft. The third gear meshes with the first gear to enable the generator to transmit power to the power terminal shaft.

[0011] In one possible implementation, the third gear is loosely fitted onto the generator shaft, and the hybrid drive shifting system further includes a third shift fork sleeve assembly, which includes a third shift fork and a third sleeve fitted onto the shaft.

[0012] The third shift fork is used to drive the third sliding sleeve to move so that the third sliding sleeve engages or disengages from the third gear, thereby forming a gear mode in which the generator and the engine jointly output power, or a gear mode in which the engine or the generator outputs power alone.

[0013] In one possible implementation, the transmission structure of the first gear and the power terminal shaft includes an intermediate shaft, on which a fourth gear meshes with the first gear and a fifth gear meshes with a sixth gear on the power terminal shaft.

[0014] The hybrid drive shifting system also includes a fourth shift fork sliding sleeve assembly, which includes a fourth shift fork and a fourth sliding sleeve. Any one of the fourth gear, the fifth gear, and the sixth gear is loosely fitted. The fourth sliding sleeve is mounted on the shaft where the loosely fitted gear is located and is used to mesh or disengage with the loosely fitted gear, so that the generator shaft can be connected to the power terminal shaft to transmit power and can be disengaged from the power terminal shaft to enable a charging mode.

[0015] In one possible implementation, the third shift fork slide group and the fourth shift fork slide group form a second shift fork mechanism, the second shift fork slide mechanism further including a second shift fork shaft and a second shift block sleeved on the second shift fork shaft;

[0016] Both the third and fourth shift forks are fixedly connected to the second shift block, and the second shift block drives the third and fourth shift forks to move by means of a shift lever or a drive mechanism.

[0017] In one possible implementation, the generator shaft is connected to the ninth gear on the first shaft via an eighth gear, so that the generator has a charging mode and a power output mode. The third shift fork is sleeved on the second shift fork shaft, and the second shift fork shaft is also provided with a second shift block. The second shift block is connected to the shift handle or the second drive mechanism to drive the third shift fork to move.

[0018] In one possible implementation, a control system is also included.

[0019] The first shift block, which moves the first shift fork and the second shift fork, is driven by a first drive mechanism, and the second shift block is connected by a second drive mechanism. The control system includes a controller and a command component. The controller is used to control the first drive mechanism and the second drive mechanism according to the shift command of the command component.

[0020] In one possible implementation, the instruction component includes any one or any combination of a button, a rotary knob, and a voice acquisition device.

[0021] This application also provides a vehicle including the hybrid drive shifting system as described in any of the preceding claims.

[0022] The hybrid drive shifting system provided in this application includes a shift fork and a sliding sleeve assembly between the engine's drive shaft and the power terminal shaft, and another shift fork and sliding sleeve assembly between the drive motor's drive shaft and the power terminal shaft. The shift fork is driven by a shift lever or drive mechanism to move the sliding sleeve, causing the gears of the sliding sleeve and the neutral sleeve to mesh and transmit power. The gears of the sliding sleeve and the neutral sleeve can also be disengaged to disconnect power. Thus, the two sets of shift fork and sliding sleeve assemblies can achieve three gearing modes: engine-only power output, drive motor-only power output, and combined engine and drive motor power output. This design eliminates the need for multiple clutches and gear sets with different transmission ratios, achieving hybrid power mode and gear switching through a simple component composition and transmission structure. In each gearing mode, the automatic transmission vehicle can adjust the vehicle speed according to the driver's accelerator pedal input.

[0023] Therefore, the gear shifting system provided in this application meets the driving needs of power switching and speed switching of the vehicle. Moreover, the gear shifting system has a simple structure, which not only helps to save costs but also reduces the space occupation requirements and makes it easy to install on the vehicle.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please refer to the attached document. Figures 1-6 The embodiments of this application provide a hybrid drive shifting system, which includes an engine 16, a drive motor 14, and a first shift fork mechanism. The drive shaft of the engine 16 is connected to a first shaft 5 (the two shafts can also be an integral shaft). A first gear 6 is loosely fitted on the first shaft 5. The first gear 6 is used to drive and connect with the power terminal shaft 10, such as the first gear 6 directly meshing with the gear on the power terminal shaft 10, or the first gear 6 meshing with the gear on the intermediate shaft 18, and the intermediate shaft 18 is connected to the power terminal shaft 10 through a gear set. The drive shaft of the drive motor 14 is connected to a second shaft (the two shafts can also be an integral shaft). The second shaft is driven and connected to the power terminal shaft 10 through a gear set. The gear set includes a loosely fitted second gear 9, that is, the second gear 9 is loosely fitted on the second shaft or loosely fitted on the power terminal shaft 10.

[0034] The first shift fork mechanism includes a first shift fork sleeve assembly and a second shift fork sleeve assembly. The first shift fork sleeve assembly has a first shift fork 3 and a first sleeve 7 connected to the first shift fork 3. The second shift fork sleeve assembly has a second shift fork 4 and a second sleeve 8 connected to the second shift fork 4. The first sleeve 7 is sleeved and connected to the first shaft 5 and rotates synchronously with the first shaft 5. The first sleeve 7 is used to engage or disengage with the first gear 6, which is loosely fitted on the first shaft 5. When the first sleeve 7 and the first gear 6 are engaged, the first gear 6 can be driven to rotate, and the drive shaft of the engine 16 can output power to the power terminal shaft 10 through the first gear 6. When the first sleeve 7 and the first gear 6 are disengaged, the first sleeve 7 cannot drive the first gear 6 to rotate, the drive shaft of the engine 16 is disconnected from the power terminal shaft 10, and power cannot be transmitted.

[0035] The second sliding sleeve 8 is connected to the shaft where the second gear 9 is located and rotates synchronously with the shaft. It is used to engage or disengage with the second gear 9. When the second sliding sleeve 8 and the second gear 9 are engaged, the drive shaft of the drive motor 14 can transmit power to the power terminal shaft 10. When the second sliding sleeve 8 and the second gear 9 are disengaged, it cannot drive the second gear 9 to rotate, and the drive shaft of the drive motor 14 cannot transmit power to the power terminal shaft 10.

[0036] The first shift fork 3 moves the first sliding sleeve 7 to adjust the engagement and disengagement of the first sliding sleeve 7 with the first gear 6. The second shift fork 4 moves the second sliding sleeve 8 to adjust the engagement and disengagement of the second sliding sleeve 8 with the second gear 9. Thus, by adjusting the first shift fork 3 and the second shift fork 4, three gearing modes can be formed: only the engine 16 outputs power, only the drive motor 14 outputs power, and both the engine 16 and the drive motor 14 output power. In other words, the shift forks can switch the driving power used, forming three modes. Each mode has a different power output due to the different driving power used. Furthermore, the transmission paths of the first gear 6 and the second gear 9 can be set to have different transmission ratios, thus creating three different gears.

[0037] As can be seen, the hybrid drive shifting system provided in this application has a shift fork and sleeve assembly (hereinafter referred to as shift fork and sleeve assembly) between the drive shaft of the engine 16 and the power terminal shaft 10, and a shift fork and sleeve assembly is also provided between the drive shaft of the drive motor 14 and the power terminal shaft 10. The shift fork is driven by the shift lever or drive mechanism to move the sleeve, so that the gears of the sleeve and the empty sleeve mesh to realize the transmission of power, and the gears of the sleeve and the empty sleeve can be separated to realize the disconnection of power. Thus, the two sets of shift fork and sleeve assemblies can realize three gear modes: only the engine 16 outputs power, only the drive motor 14 outputs power, and the engine 16 and the drive motor 14 output power together.

[0038] In automatic transmission vehicles, the vehicle speed is automatically adjusted by the control system based on the monitored throttle opening (i.e., the degree to which the driver presses the accelerator). Therefore, the shifting system provided in this application meets the driving needs for power and speed switching. Furthermore, the shifting system has a simple structure, eliminating the need for multiple clutches and gear sets with different transmission ratios. Through its simple component composition and transmission structure, it can achieve the switching of three power modes and gears in a hybrid vehicle, which not only saves costs but also reduces space requirements, making it easy to install in the vehicle.

[0039] like Figure 1 As shown, the second gear 9 can be sleeved on the power terminal shaft 10, and the drive shaft of the drive motor 14 is provided with a seventh gear 15 that meshes with the second gear 9. The second sliding sleeve 8 is provided on the power terminal shaft 10 and is connected to the power terminal shaft 10 through a spline to rotate synchronously. Figure 2 As shown, the second gear 9 has a connecting portion on the side facing the second sliding sleeve 8. The connecting portion has external gear teeth for meshing with the internal teeth of the second sliding sleeve 8. The second sliding sleeve 8 can be displaced towards the second gear 9 to fit onto the connecting portion of the second gear 9 and mesh with it. When the second sliding sleeve 8 is axially displaced away from the second gear 9, it can disengage from the second gear 9. The first gear 6 and the first sliding sleeve 7 have similar structures to achieve meshing and disengagement. In this application, the meshing and disengagement of each sliding sleeve with the corresponding gear are all achieved through this type of structure, which will not be elaborated further below.

[0040] The first shift fork mechanism also includes a first shift fork shaft 2 and a first shift block 1 slidably sleeved on the first shift fork shaft 2. The first shift fork 3 and the second shift fork 4 are both slidably sleeved on the first shift fork shaft 2 and are both fixedly connected to the first shift block 1. The first shift block 1 drives the first shift fork 3 and the second shift fork 4 to move synchronously through the shift lever or the first drive mechanism to adjust the first sliding sleeve 7 and the second sliding sleeve 8. It can form three positions: the first sliding sleeve 7 and the first gear 6 are engaged, the second sliding sleeve 8 and the second gear 9 are disengaged, the first sliding sleeve 7 and the first gear 6 are engaged, the second sliding sleeve 8 and the second gear 9 are engaged, and the first sliding sleeve 7 and the first gear 6 are disengaged, the second sliding sleeve 8 and the second gear 9 are engaged. Thus, three gear modes are formed accordingly.

[0041] For example, such as Figures 3-5 As shown, specifically, the first shift block 1 can be connected to the first drive mechanism. For example, the first drive mechanism includes a cylinder, which drives the first shift block 1 to move back and forth on the first shift fork shaft 2. The first shift fork 3 and the second shift fork 4 can be located on opposite sides of the first shift block 1's axial direction. The first shift block 1, along with the first shift fork 3 and the second shift fork 4, is displaced and can move to a first position where the first sliding sleeve 7 and the first gear 6 are fully engaged (the radial projections of their teeth are essentially completely coincident) and the second sliding sleeve 8 and the second gear 9 are separated. Figure 3 As shown; when the first shift block 1 is driven to move the first shift fork 3 and the second shift fork 4 in the direction of separating the first sliding sleeve 7 and the first gear 6, the first sliding sleeve 7 and the first gear 6 are slightly misaligned in the axial direction, but the teeth of the first sliding sleeve 7 and the first gear 6 are still meshed, only their radial projections partially overlap. The second sliding sleeve 8 is partially fitted onto the second gear 9, and their teeth are meshed, but their radial projections only partially overlap. At this point, the device has moved to the second position where the first sliding sleeve 7 and the first gear 6 are meshed, and the second sliding sleeve 8 and the second gear 9 are meshed. Figure 4 As shown; when the second drive block, along with the first shift fork 3 and the second shift fork 4, continues to move in the direction of separating the first sliding sleeve 7 and the first gear 6, the first sliding sleeve 7 and the first gear 6 are completely separated and disengaged, while the teeth of the second sliding sleeve 8 and the second gear 9 remain engaged and their radial projections are almost completely overlapping. At this point, the device has moved to the third position where the first sliding sleeve 7 and the first gear 6 are separated, and the second sliding sleeve 8 and the second gear 9 are engaged. Figure 5 As shown.

[0042] With this configuration, the first shift fork mechanism reacts quickly, the shifting action is smooth and fast, and the gear switching response is sensitive.

[0043] Hybrid power systems typically include a generator 13; therefore, this application further considers the generator 13 as a driving force as well. For example, a third gear 11 is provided on the shaft of the generator 13, and the third gear 11 meshes with the first gear 6. Thus, the generator 13 is used as a drive motor, and its shaft rotation transmits power to the power terminal shaft 10 via the third gear 11 and the first gear 6. Therefore, when the first sliding sleeve 7 and the first gear 6 are meshed, the engine 16 and the generator 13 can jointly output power, forming a gear mode.

[0044] Furthermore, the third gear 11 is loosely fitted on the rotating shaft of the generator 13. The hybrid drive shifting system also includes a third shift fork sliding sleeve assembly, which includes a third shift fork 24 and a third sliding sleeve 12 fitted on the rotating shaft. The third shift fork 24 and the third sliding sleeve 12 are connected and used to drive the third sliding sleeve 12 to move, so that the third sliding sleeve 12 engages or disengages with the third gear 11. Thus, when the first sliding sleeve 7 and the first gear 6 are engaged, and the third sliding sleeve 12 and the third gear 11 are also engaged, the generator 13's shaft can transmit power to the third gear 11, and the engine 16 and the generator 13 together output power to the power terminal shaft 10 through the first gear 6. When the first sliding sleeve 7 and the first gear 6 are engaged, but the third sliding sleeve 12 and the third gear 11 are disengaged, the generator 13's shaft cannot transmit power to the third gear 11; in this case, only the engine 16 transmits power to the power terminal shaft 10. When the first sliding sleeve 7 and the first gear 6 are disengaged, but the third sliding sleeve 12 and the third gear 11 are engaged, the generator 13 transmits power to the power terminal shaft 10 through the third gear 11 and the first gear 6, while the engine 16 cannot transmit power. By combining the engagement and disengagement of the second sliding sleeve 8 and the second gear 9, three different power transmission scenarios can also be formed.

[0045] Therefore, as can be seen from the above, if the above embodiments of this application are combined, the hybrid drive shifting system provided by this application can form six gear modes: First, the first sliding sleeve 7 and the first gear 6 are engaged, the second sliding sleeve 8 and the second gear 9 are disengaged, the third sliding sleeve 12 and the third gear 11 are engaged, and the generator 13 and the engine 16 jointly output power; Second, the first sliding sleeve 7 and the first gear 6 are engaged, the second sliding sleeve 8 and the second gear 9 are disengaged, the third sliding sleeve 12 and the third gear 11 are disengaged, and the engine 16 outputs power alone; Third, the first sliding sleeve 7 and the first gear 6 are disengaged, the second sliding sleeve 8 and the second gear 9 are disengaged, the third sliding sleeve 12 and the third gear 11 are engaged, and the generator 13 outputs power alone; Fourth, the first sliding sleeve 7 and the first gear 6 are disengaged, the second sliding sleeve 8 and the second gear 9 are disengaged, the third sliding sleeve 12 and the third gear 11 are engaged, and the generator 13 outputs power alone; The first gear mode is characterized by the following configurations: 8 and 9 are engaged, the third sleeve 12 and the third gear 11 are disengaged, and the drive motor 14 outputs power independently; 5, the first sleeve 7 and the first gear 6 are engaged, the second sleeve 8 and the second gear 9 are engaged, the third sleeve 12 and the third gear 11 are disengaged, and the drive motor 14 and the engine 16 output power together; 6, the first sleeve 7 and the first gear 6 are disengaged, the second sleeve 8 and the second gear 9 are engaged, the third sleeve 12 and the third gear 11 are engaged, and the drive motor 14 and the generator 13 output power together; 7, the first sleeve 7 and the first gear 6 are engaged, the second sleeve 8 and the second gear 9 are engaged, the third sleeve 12 and the third gear 11 are engaged, and the drive motor 14, the generator 13, and the engine 16 output power together.

[0046] When it is necessary to switch to the charging mode of generator 13, simply disconnect the power transmission path between the rotating shaft of generator 13 and the power terminal shaft 10.

[0047] For example, the transmission structure of the first gear 6 and the power terminal shaft 10 includes an intermediate shaft 18, on which a fourth gear 17 and a fifth gear 19 are mounted. A sixth gear 20 is mounted on the power terminal shaft 10. The fourth gear 17 meshes with the first gear 6, and the fifth gear 19 meshes with the sixth gear 20. Any one of the fourth gear 17, fifth gear 19, or sixth gear 20 is left unmounted. The hybrid drive shifting system also includes a fourth shift fork sleeve assembly, which includes a fourth shift fork 25 and a fourth sleeve 21 connected to the fourth shift fork 25. The fourth sleeve 21 is mounted on the shaft containing the unmounted gear and is used to engage or disengage with the unmounted gear. Figure 1 As shown, if the sixth gear 20 is empty and the fourth sliding sleeve 21 is installed on the power terminal shaft 10, when the fourth sliding sleeve 21 and the sixth gear 20 are meshed and connected, the generator 13 shaft can transmit power to the power terminal shaft 10. When the fourth sliding sleeve 21 and the sixth gear 20 are separated, the generator 13 shaft is separated from the power terminal shaft 10, and the generator 13 can enter the charging mode.

[0048] The third shift fork 24 and the fourth shift fork 25 can also be driven by the same handle or drive mechanism. For example, the third shift fork sliding sleeve group and the fourth shift fork sliding sleeve group form a second shift fork mechanism. The second shift fork mechanism also includes a second shift fork shaft 22 and a second shift block 23 sleeved on the second shift fork shaft 22. The third shift fork 24 and the fourth shift fork 25 are both sleeved on the second shift fork shaft 22 and are both fixedly connected to the second shift block 23. The second shift block 23 is driven by the shift handle or drive mechanism to move back and forth along the second shift fork shaft 22 and drive the third shift fork 24 and the fourth shift fork 25 to move.

[0049] Preferably, the second shift block 23 is connected to the second drive mechanism. The second drive mechanism includes a power component such as a cylinder or a motor. The power component drives the second shift block 23 to reciprocate along the second shift fork shaft 22. The second shift block 23 simultaneously drives the third shift fork 24 and the fourth shift fork 25 to move, forming three position states: the third sliding sleeve 12 and the third gear 11 are engaged, and the fourth sliding sleeve 21 and the fourth gear 17 are disengaged (corresponding to the charging mode); the third sliding sleeve 12 and the third gear 11 are engaged, and the fourth sliding sleeve 21 and the fourth gear 17 are engaged (applicable to the first, third, and sixth gear modes mentioned above); and the third sliding sleeve 12 and the third gear 11 are disengaged, and the fourth sliding sleeve 21 and the fourth gear 17 are engaged (applicable to the second, fourth, fifth, and seventh gear modes mentioned above).

[0050] The specific implementation details are the same as those in the first shift fork mechanism described above, and will not be repeated here.

[0051] With this configuration, seven gear modes and a charging mode can be switched and adjusted through the cooperation of two sets of shift fork mechanisms. In simple terms, when the fourth gear 17 and the fourth sliding sleeve 21 are engaged, seven gear modes can be formed by adjusting the first sliding sleeve 7, the second sliding sleeve 8, and the third sliding sleeve 12. The engine 16, generator 13, and drive motor 14 can output independently, or they can be combined in pairs or in all three groups, as detailed above. When the fourth gear 17 and the fourth sliding sleeve 21 are disengaged, the third sliding sleeve 12 and the third gear 11 are engaged, forming the generator 13 charging mode (in the charging mode, the first sliding sleeve 7 and the second sliding sleeve 8 are usually disengaged from the gears).

[0052] Of course, besides setting a fourth shift fork sliding sleeve assembly between the intermediate shaft 18 and the power terminal shaft 10 to achieve the charging mode of the generator 13, the generator 13's rotating shaft can also be connected to the ninth gear on the first shaft 5 via the eighth gear. In this way, by keeping the first sliding sleeve 7 and the first gear 6 separated, and the third sliding sleeve 12 and the third gear 11 engaged, both the engine 16 and the generator 13 can be disconnected from the power terminal shaft 10. The engine 16's drive shaft can rotate freely on the first shaft 5 with the first gear 6, and through the first gear 6 and the third gear 11, it can drive the generator 13's rotating shaft to rotate, thus charging the generator 13. In this embodiment, there is no need to set a fourth shift fork sliding sleeve assembly; only the third shift fork 24 is fitted onto the second shift fork shaft 22. The second shift block 23 on the second shift fork shaft 22 is connected to the shift lever or the second drive mechanism to drive the third shift fork 24 to move.

[0053] The hybrid drive shifting system also includes a control system. The first drive mechanism drives the first shift block 1 to a certain displacement, and the second drive mechanism drives the second shift block 23 to a certain displacement. The controller of the control system is electrically connected to the power components of the first drive mechanism and the second drive mechanism. The control system also includes an instruction component that is communicatively connected to the controller. The instruction component is used to receive shifting instructions, and the controller is used to control the operation of the first drive mechanism and the second drive mechanism according to the shifting instructions from the instruction component.

[0054] Specifically, the instruction components include any one or any combination of buttons, rotary knobs, and voice acquisition devices.
