[0021] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0022] like Figure 1As shown, this application provides a drive system 1 for use in a vehicle. The drive system 1 is located inside the vehicle. The drive system 1 can provide power output to the vehicle, avoids the fuel loss caused by gear idling, and improves operating efficiency.

[0023] The drive system 1 includes a drive module 11, which is operable to output speed and torque. The drive module 11 includes a drive source such as an engine and / or an electric motor. The drive module 11 provides power to the drive system 1, enhancing power output and thus increasing the output power and torque range. The drive module 11 can be independently controlled, allowing for precise adjustment of power output during vehicle gear shifts.

[0024] The drive system 1 also includes an output module connected to the walking module. The walking module includes walking wheels connected to the output module. The output module is capable of outputting power to drive the walking wheels to rotate and move. The output module includes an output shaft 13 for transmitting power to the walking module (e.g., the walking wheels). The drive module 11 outputs power to the output shaft 13.

[0025] The drive module 11 includes an input gear that is rotatable. The drive module 11 actuates to cause the input gear to rotate. The drive module 11 may include an engine, a crankshaft, and an input gear connected to the crankshaft. The engine performs work to rotate the crankshaft, which in turn drives the input gear to rotate. The drive module 11 transmits power to the output shaft 13 via the input gear. The axial direction of the input gear is parallel to the axial direction of the output shaft 13.

[0026] The drive system 1 also includes a first shift sleeve 30 and a second shift sleeve 40, which can switch between multiple gears through different transmission paths. The first shift sleeve 30 can move to switch between different gears, thereby changing the power transmission path and gear ratio to meet the vehicle's needs under different driving conditions. Similarly, the second shift sleeve 40 can move to switch between different gears, thereby changing the power transmission path and gear ratio to meet the vehicle's needs under different driving conditions.

[0027] The drive system 1 also includes a transmission gear 21, which is loosely fitted onto the output shaft 13. The transmission gear 21 is connected to the output shaft 13 via a second shift sleeve 40. A bearing is provided between the transmission gear 21 and the output shaft 13. For example, a rolling bearing is provided between the transmission gear 21 and the output shaft 13. The rotation of the transmission gear 21 drives the output shaft 13 to rotate via the second shift sleeve 40. The drive system 1 includes multiple transmission gears 21, all of which are loosely fitted onto the output shaft 13. All of the multiple transmission gears 21 are connected to the output shaft 13 via the second shift sleeve 40.

[0028] The drive module 11 is connected to the output shaft 13 via the first shift sleeve 30. The input gear is also connected to the output shaft 13 via the first shift sleeve 30. The power output by the drive module 11 is transmitted to the output shaft 13 via the first shift sleeve 30. The power output by the drive module 11 can directly drive the output shaft 13 to rotate via the first shift sleeve 30.

[0029] The drive module 11 is connected to the output shaft 13 via a first shift sleeve 30 and a second shift sleeve 40. The drive module 11 is connected to the transmission gear 21 via the first shift sleeve 30. The input gear is connected to the transmission gear 21 via the first shift sleeve 30. The power output from the drive module 11 is transmitted to the transmission gear 21 via the first shift sleeve 30, and then to the output shaft 13 via the transmission gear 21. The power output from the transmission gear 21 is transmitted to the output shaft 13 via the second shift sleeve 40. The power output from the drive module 11 can indirectly drive the output shaft 13 to rotate via the transmission gear 21.

[0030] In this way, the first shift sleeve 30 can transmit the power of the drive module 11 to the output shaft 13 through different paths, so that the drive module 11 can work to provide power output, reducing drag loss and oil churning loss.

[0031] Furthermore, the first shift sleeve 30 includes at least two shift teeth, which are spaced apart. The input gear is connected to one of the at least two shift teeth, the output shaft is connected to the other of the at least two shift teeth, and the transmission gear is connected to yet another of the at least two shift teeth. Thus, the input gear can be connected to one shift tooth, and the other shift tooth can be connected to the output shaft. Alternatively, the input gear can be connected to one shift tooth, and the other shift tooth can be connected to the transmission gear, which in turn connects to the output shaft. This enables the switching between different gears.

[0032] According to the drive system 1 of this application, the drive system 1 includes a drive module, an output module, and a shift module. The drive module includes an input gear that is rotatable. The output module includes an output shaft 13. The shift module includes a first shift sleeve 30, a second shift sleeve 40, and a gear 21. The input gear is connected to the output shaft 13 via the first shift sleeve 30, or the input gear is connected to the output shaft 13 via the first shift sleeve 30 and the second shift sleeve 40. The gear 21 is loosely fitted onto the output shaft 13 and connected to the output shaft 13 via the second shift sleeve 40. The first shift sleeve 30 includes at least two shift teeth. The input gear is connected to one of the at least two shift teeth, the output shaft 13 is connected to the other of the at least two shift teeth, and the gear 21 is connected to the third of the at least two shift teeth. Thus, both the first shift sleeve 30 and the second shift sleeve 40 can allow the power of the drive module 11 to be transmitted to the output shaft 13 through different paths, realizing the switching of different gears.

[0033] Furthermore, the shift module includes a first gear 211 and a second gear 212, both of which are loosely fitted onto the output shaft 13. The first gear 211 and the second gear 212 are spaced apart. Preferably, the first gear 211 and the second gear 212 are spaced apart along the axial direction of the output shaft 13. The axial direction of the first gear 211 is parallel to the axial direction of the output shaft 13. A bearing is provided between the first gear 211 and the output shaft 13. The first gear 211 has a through hole through which the output shaft 13 passes. For example, a rolling bearing is provided between the first gear 211 and the output shaft 13. Rotation of the first gear 211 does not directly drive rotation of the output shaft 13. The first gear 211 is constructed in a generally disc-shaped manner. The first shift sleeve 30 includes a first shift tooth 311, a second shift tooth 312, a third shift tooth 313, and a first moving member 314, wherein the first shift tooth 311, the second shift tooth 312, and the third shift tooth 313 are spaced apart. The first moving member 314 is movable to connect with different shift teeth respectively.

[0034] The first shift tooth 311 is connected to the output shaft 13. The first shift tooth 311 is fixedly connected to the output shaft 13. The output shaft 13 is fixedly connected to the first shift tooth 311. The axial direction of the first shift tooth 311 is parallel to the axial direction of the output shaft 13. Preferably, the first shift sleeve 30 includes a first shift gear, which is generally disc-shaped. The first shift tooth 311 is a tooth of the first shift gear. The output shaft 13 is fixedly connected to the center of the first shift gear. Rotation of the first shift tooth 311 can drive the output shaft 13 to rotate. The first moving member 314 can be connected to the first shift tooth 311. For example, the first moving member 314 can mesh with the first shift tooth 311. When the first moving member 314 is connected to the first shift tooth 311, rotation of the first moving member 314 can drive the first shift tooth 311 to rotate, thereby driving the output shaft 13 to rotate.

[0035] The second shift gear 312 is connected to the drive module 11. Preferably, the second shift gear 312 is connected to the input gear. The second shift gear 312 is fixedly connected to the input gear. Rotation of the input gear can drive the second shift gear 312 to rotate. The power output by the drive module 11 can be transmitted to the second shift gear 312. The first moving member 314 can be connected to the second shift gear 312. For example, the first moving member 314 meshes with the second shift gear 312. When the first moving member 314 is connected to the second shift gear 312, rotation of the second shift gear 312 can drive the first moving member 314 to rotate.

[0036] The third shift tooth 313 is loosely fitted onto the output shaft 13. For example, the first shift sleeve 30 includes a third shift gear, which is generally disc-shaped. The third shift tooth 313 is a tooth of the third shift gear. The third shift gear has a through hole. The output shaft 13 passes through the through hole. For example, a bearing is provided between the third shift gear and the output shaft 13. The rotation of the third shift tooth 313 does not directly drive the output shaft 13 to rotate. The rotation of the output shaft 13 does not directly drive the third shift tooth 313 to rotate. The third shift tooth 313 is connected to the first transmission gear 211. For example, the third shift gear is connected to the first transmission gear 211. The end surface of the third shift gear is fixedly connected to the end surface of the first transmission gear 211. The rotation of the third shift tooth 313 can drive the first transmission gear 211 to rotate. When the first moving member 314 is connected to the third shift gear 313, the rotation of the first moving member 314 can drive the third shift gear 313 to rotate, thereby driving the first transmission gear 211 to rotate.

[0037] The first moving member 314 may be selectively connected to either the first shift tooth 311 or the third shift tooth 313.

[0038] In one optional implementation, the first moving member 314 is connected to both the first shift gear 311 and the second shift gear 312. Rotation of the second shift gear 312 can drive the first moving member 314 to rotate, thereby driving the first shift gear 311 to rotate, and in turn driving the output shaft 13 to rotate.

[0039] In one optional implementation, the first moving member 314 is connected to the second shift tooth 312, and the first moving member 314 is spaced apart from the first shift tooth 311 and the third shift tooth 313. The rotation of the second shift tooth 312 will not cause the first shift tooth 311 and the third shift tooth 313 to rotate.

[0040] In one optional implementation, the first moving member 314 is connected to both the second shift gear 312 and the third shift gear 313. Rotation of the second shift gear 312 can drive the first moving member 314 to rotate, thereby driving the third shift gear 313 to rotate, which in turn drives the transmission gear 21 to rotate, and in turn drives the output shaft 13 to rotate.

[0041] The first shift gear 311 and the second shift gear 312 are located on both sides of the first moving member 314 along the radial direction of the output shaft 13. The first shift gear 311 and the second shift gear 312 are spaced apart along the radial direction of the output shaft 13. The first shift gear 311 and the second shift gear 312 are arranged opposite each other along the radial direction of the output shaft 13. The third shift gear 313 and the second shift gear 312 are located on both sides of the first moving member 314 along the radial direction of the output shaft 13. The third shift gear 313 and the second shift gear 312 are spaced apart along the radial direction of the output shaft 13. The third shift gear 313 and the second shift gear 312 are arranged opposite each other along the radial direction of the output shaft 13. This saves space in the axial direction of the output shaft 13 and allows for the avoidance of the drive module 11.

[0042] The first moving member 314 is movable between different positions. The first moving member 314 is movable between a first empty position, a first left position, and a first right position. The first left position is closer to the drive module 11 than the first right position. The first moving member 314 located in the first empty position can move to the first left position. The first moving member 314 located in the first left position can move to the first empty position. The first moving member 314 located in the first empty position can move to the first right position. The first moving member 314 located in the first right position can move to the first empty position.

[0043] The first movable member 314, located in the first empty position, is connected to the second shift gear 312 to connect to the input gear. The first movable member 314, located in the first empty position, is connected to the second shift gear 312. The first movable member 314, located in the first empty position, is connected to the input gear.

[0044] The first moving member 314, located in the first empty position, is spaced apart from the first shifting tooth 311. The first moving member 314, located in the first empty position, is also spaced apart from the third shifting tooth 313. The rotation of the second shifting tooth 312 will not cause the first shifting tooth 311 to rotate, nor will it cause the third shifting tooth 313 to rotate, nor will it cause the output shaft 13 to rotate, thus reducing oil stirring losses.

[0045] The rotation of the first shift gear 311 will not cause the first moving member 314 located in the first empty position to rotate, nor will it cause the second shift gear 312 to rotate. Similarly, the rotation of the third shift gear 313 will not cause the first moving member 314 located in the first empty position to rotate, nor will it cause the second shift gear 312 to rotate. Thus, the rotation of the output shaft 13 and the transmission gear 21 will not cause the first moving member 314 located in the first empty position to rotate, nor will it cause the second shift gear 312 to rotate, nor will it cause the input gear to rotate, reducing oil churning losses and reducing drag losses of the drive module 11.

[0046] A first moving member 314 located in the first left position connects to a first shift gear 311 and a second shift gear 312. The first moving member 314 in the first left position meshes with the first shift gear 311. The first moving member 314 in the first left position also meshes with the second shift gear 312. When the drive module 11 operates, it causes the input gear to rotate, thereby driving the second shift gear 312 to rotate. The input gear is connected to the output shaft 13 via the first moving member 314 in the first left position. The rotation of the second shift gear 312 drives the first moving member 314 in the first left position to rotate, and the first moving member 314 in the first left position drives the first shift gear 311 to rotate, thereby driving the output shaft 13 to rotate.

[0047] The first moving member 314, located in the first right position, connects to the second shift gear 312 and the third shift gear 313. The first moving member 314 in the first right position meshes with the second shift gear 312. The first moving member 314 in the first right position meshes with the third shift gear 313. When the drive module 11 operates, it causes the input gear to rotate, thereby driving the second shift gear 312 to rotate. The input gear is connected to the first transmission gear 211 via the first moving member 314 in the first right position. The rotation of the second shift gear 312 drives the first moving member 314 in the first right position to rotate, and the first moving member 314 in the first right position drives the third shift gear 313 to rotate, thereby driving the first transmission gear 211 to rotate.

[0048] For example, the end surface of the third shift gear is fixed to the end surface of the first gear 211. This allows the third shift gear 313 to connect with the first gear 211. Rotation of the third shift gear 313 drives the first gear 211 to rotate. The first moving member 314, located in the first right position, can drive the third shift gear 313 to rotate, thereby driving the first gear 211 to rotate.

[0049] The first shift gear 311 and the third shift gear 313 are located at opposite ends of the first moving member 314 along the axial direction of the output shaft 13. The first moving member 314 is movable between a first left position and a first right position along the axial direction of the output shaft 13. Thus, the first moving member 314 moves along the axial direction of the output shaft 13 to connect with the first shift gear 311 and the second shift gear 312 respectively. This prevents misalignment of the first moving member 314 from causing shifting misalignment.

[0050] To ensure the output speed of the drive module 11 better matches the operating conditions, the drive module includes an input shaft 111, a first input gear 611, and a second input gear 612, which mesh with each other. The diameter of the first input gear 611 is smaller than the diameter of the second input gear 612. The first input gear 611 is connected to the input shaft 111. The input shaft 111 is directly connected to the first input gear 611. The center of the first input gear 611 is connected to the end of the input shaft 111. Rotation of the input shaft 111 drives the first input gear 611 to rotate. The input shaft 111 is connected to the second input gear 612 via the first input gear 611. Thus, the power output from one input shaft can be distributed to multiple input gears.

[0051] The second input gear 612 is loosely fitted onto the output shaft 13. The second input gear 612 has a through hole, through which the output shaft 13 passes. A bearing is provided between the second input gear 612 and the output shaft 13. For example, a rolling bearing is provided between the second input gear 612 and the output shaft 13. Rotation of the second input gear 612 does not directly drive the output shaft 13 to rotate. The second input gear 612 is connected to a second shift gear 312. The second input gear 612 and the second shift gear 312 are fixed together. The end surface of the second input gear 612 is fixed to the second shift gear 312. Rotation of the second input gear 612 can drive the second shift gear 312 to rotate. The first moving member 314 is arranged on the second input gear 612 and can slide left and right.

[0052] The rotation of input shaft 111 drives the first input gear 611 to rotate, which in turn drives the second input gear 612 to rotate. The rotation of the second input gear 612 then drives the second shift gear 312 to rotate.

[0053] In one optional implementation, the second shift gear 312 can be connected to the first moving member 314 located in the first left position. The second shift gear 312 can drive the first moving member 314 located in the first left position to rotate. The first moving member 314 located in the first left position can drive the first shift gear 311 to rotate, thereby driving the output shaft 13 to rotate.

[0054] In one optional implementation, the second shift gear 312 can be connected to the first moving member 314 located in the first right position. The second shift gear 312 can drive the first moving member 314 located in the first right position to rotate. The first moving member 314 located in the first right position can drive the third shift gear 313 to rotate, thereby driving the transmission gear 21 (first transmission gear 211) to rotate.

[0055] The drive system 1 also includes an intermediate shaft 22, through which the first gear 211 is connected to the second gear 212. The axial direction of the intermediate shaft 22 is parallel to the axial direction of the output shaft 13. Further, the drive system 1 also includes a third gear 213, which meshes with the first gear 211. The axial direction of the third gear 213 is parallel to the axial direction of the output shaft 13. The third gear 213 is connected to the intermediate shaft 22. The center of the third gear 213 is fixedly connected to the intermediate shaft 22. Rotation of the first gear 211 can drive the third gear 213 to rotate. Rotation of the third gear 213 can drive the intermediate shaft 22 to rotate. Correspondingly, rotation of the intermediate shaft 22 can also drive the third gear 213 to rotate. Rotation of the third gear 213 can also drive the first gear 211 to rotate.

[0056] The drive system 1 includes two third gears 213 and two intermediate shafts 22, with the two third gears 213 connected to the two intermediate shafts 22 respectively. The two third gears 213 are located on either side of the first gear 211. The first gear 211 meshes with both third gears 213 simultaneously. Rotation of the first gear 211 drives the two third gears 213 to rotate simultaneously, which in turn drives the two intermediate shafts 22 to rotate.

[0057] The drive system 1 also includes a fourth gear 214, which meshes with the second gear 212. The axial direction of the fourth gear 214 is parallel to the axial direction of the output shaft 13. The fourth gear 214 is connected to the intermediate shaft 22. The center of the fourth gear 214 is fixedly connected to the intermediate shaft 22. Rotation of the intermediate shaft 22 can also drive the fourth gear 214 to rotate. Rotation of the fourth gear 214 can drive the second gear 212 to rotate. Correspondingly, rotation of the second gear 212 can also drive the fourth gear 214 to rotate. Rotation of the fourth gear 214 can also drive the intermediate shaft 22 to rotate.

[0058] The drive system 1 also includes two fourth gears 214, which are respectively connected to two intermediate shafts 22. The two fourth gears 214 are located on either side of the second gear 212. The second gear 212 meshes with both fourth gears 214 simultaneously. Rotation of the second gear 212 drives both fourth gears 214 to rotate simultaneously, thereby driving the two intermediate shafts 22 to rotate.

[0059] The second shift sleeve 40 is located between the first gear 211 and the second gear 212 along the axial direction of the output shaft 13. The first gear 211 and the second gear 212 are located on both sides of the second shift sleeve 40 along the axial direction of the output shaft 13. The second shift sleeve 40 can be connected to the first gear 211 and the second gear 212 respectively.

[0060] Specifically, the second shift sleeve 40 includes a fourth shift tooth 411, which is connected to the output shaft 13. The fourth shift tooth 411 is fixedly connected to the output shaft 13. The second shift sleeve 40 may include a fourth shift gear, which is generally disc-shaped. The fourth shift tooth 411 is a tooth of the fourth shift gear. The output shaft 13 is fixedly connected to the center of the fourth shift gear. Rotation of the fourth shift tooth 411 can drive the output shaft 13 to rotate.

[0061] The second shift sleeve 40 also includes a fifth shift tooth 412, which is loosely fitted onto the output shaft 13. The fourth shift tooth 411 and the fifth shift tooth 412 are spaced apart along the axial direction of the output shaft 13. For example, the second shift sleeve 40 includes a fifth shift gear, which is generally disc-shaped. The fifth shift tooth 412 is a tooth of the fifth shift gear. The fifth shift gear has a through hole. The output shaft 13 passes through the through hole. For example, a bearing is provided between the fifth shift gear and the output shaft 13. Rotation of the fifth shift tooth 412 does not directly drive rotation of the output shaft 13. Rotation of the output shaft 13 does not directly drive rotation of the fifth shift tooth 412. The fifth shift tooth 412 is connected to the first transmission gear 211. For example, the fifth shift gear is connected to the first transmission gear 211. The end surface of the fifth shift gear is fixedly connected to the end surface of the first transmission gear 211. The rotation of the first gear 211 can drive the fifth gear 412 to rotate.

[0062] The second shift sleeve 40 also includes a second movable member 414, which is movable to connect with different shift teeth respectively. The second movable member 414 is arranged on the output shaft 13 and can slide left and right. The second movable member 414 can optionally be connected with the fourth shift tooth 411 and the fifth shift tooth 412. The second movable member 414 can be connected with the fourth shift tooth 411. For example, the second movable member 414 can mesh with the fourth shift tooth 411. When the second movable member 414 is connected with the fourth shift tooth 411, the second movable member 414 does not rotate, the fourth shift tooth 411 does not rotate, and the output shaft 13 does not rotate.

[0063] The second moving member 414 can be connected to both the fourth shift gear 411 and the fifth shift gear 412. For example, the second moving member 414 can mesh with the fourth shift gear 411, and the second moving member 414 can mesh with the fifth shift gear 412. When the second moving member 414 is connected to the fifth shift gear 412, the rotation of the fifth shift gear 412 can drive the second moving member 414 to rotate, thereby driving the output shaft 13 to rotate through the fourth shift gear 411.

[0064] The second shift sleeve 40 also includes a sixth shift tooth 413, which is loosely fitted onto the output shaft 13. For example, the second shift sleeve 40 includes a sixth shift gear, which is generally disc-shaped. The sixth shift tooth 413 is a tooth of the sixth shift gear. The sixth shift gear has a through hole. The output shaft 13 passes through the through hole. For example, a bearing is provided between the sixth shift gear and the output shaft 13. Rotation of the sixth shift tooth 413 does not directly drive rotation of the output shaft 13. Rotation of the output shaft 13 does not directly drive rotation of the sixth shift tooth 413. The sixth shift tooth 413 is fixed to the second transmission gear 212. For example, the sixth shift gear is connected to the second transmission gear 212. The end surface of the sixth shift gear is fixedly connected to the end surface of the second transmission gear 212. Rotation of the second transmission gear 212 can drive rotation of the sixth shift tooth 413.

[0065] The second moving member 414 may be selectively connected to the fourth shift tooth 411, the fifth shift tooth 412 and the sixth shift tooth 413.

[0066] As an alternative implementation, the second moving member 414 is connected to the fourth shifting tooth 411.

[0067] In one optional implementation, the second moving member 414 is connected to both the fourth shift gear 411 and the fifth shift gear 412. Rotation of the fifth shift gear 412 can drive the second moving member 414 to rotate, thereby driving the fourth shift gear 411 to rotate, and in turn driving the output shaft 13 to rotate.

[0068] In one optional implementation, the second moving member 414 is connected to both the fourth shift gear 411 and the sixth shift gear 413. Rotation of the sixth shift gear 413 can drive the second moving member 414 to rotate, thereby driving the fourth shift gear 411 to rotate, and in turn driving the output shaft 13 to rotate.

[0069] The second moving member 414 is movable between different positions. The second moving member 414 is movable between a second empty position, a second left position, and a second right position. The second empty position is located between the second left position and the second right position along the axial direction of the output shaft 13. The second left position is closer to the drive module 11 than the second right position. The second moving member 414 located in the second empty position can move to the second left position. The second moving member 414 located in the second left position can move to the second empty position. The second moving member 414 located in the second empty position can move to the second right position. The second moving member 414 located in the second right position can move to the second empty position.

[0070] The second moving member 414, located in the second empty position, is connected to the fourth shift gear 411 to connect to the output shaft 13. The second moving member 414, located in the second empty position, is connected to the fourth shift gear 411. The second moving member 414, located in the second empty position, is only connected to the output shaft 13.

[0071] The second moving member 414, located in the second empty position, is spaced apart from the fifth shift tooth 412. Rotation of the fifth shift tooth 412 will not cause the second moving member 414, located in the second empty position, to rotate, nor will it cause the fourth shift tooth 411 to rotate, thus reducing oil churning losses. The second moving member 414, located in the second empty position, is spaced apart from the sixth shift tooth 413. Rotation of the sixth shift tooth 413 will not cause the second moving member 414, located in the second empty position, to rotate, nor will it cause the fourth shift tooth 411 to rotate. Rotation of the transmission gear 21 will not cause the second moving member 414, located in the second empty position, to rotate, nor will it cause the fourth shift tooth 411 to rotate, thus reducing oil churning losses and reducing drag losses of the drive module 11.

[0072] The second moving member 414, located in the second left position, connects the fourth shift gear 411 and the fifth shift gear 412. The second moving member 414 in the second left position meshes with the fourth shift gear 411. The second moving member 414 in the second left position meshes with the fifth shift gear 412. The first transmission gear 211 is connected to the output shaft 13 via the second moving member 414 in the second left position. Rotation of the first transmission gear 211 drives the fifth shift gear 412 to rotate. Rotation of the fifth shift gear 412 drives the second moving member 414 in the second left position to rotate, which in turn drives the fourth shift gear 411 to rotate, thereby driving the output shaft 13 to rotate.

[0073] The second moving member 414, located in the second right position, connects the fourth shift gear 411 and the sixth shift gear 413. The second moving member 414 in the second right position meshes with the fourth shift gear 411. The second moving member 414 in the second right position meshes with the sixth shift gear 413. The second transmission gear 212 is connected to the output shaft via the second moving member 414 in the second right position. Rotation of the second transmission gear 212 drives the sixth shift gear 413 to rotate. Rotation of the sixth shift gear 413 drives the second moving member 414 in the second right position to rotate. The second moving member 414 in the second right position drives the fourth shift gear 411 to rotate, thereby driving the output shaft 13 to rotate.

[0074] As an alternative implementation method, such as Figure 2As shown, the drive system 1 includes at least two second shift sleeves 40, which are spaced apart along the axial direction of the output shaft 13. For example, two second shift sleeves 40 are spaced apart. Of course, the drive system 1 includes a larger number of second shift sleeves 40, such as three, four, or five, which are spaced apart along the output shaft 13. The drive system 1 includes three second shift sleeves 40, which are spaced apart along the axial direction of the output shaft 13.

[0075] This application also provides a vehicle that includes the aforementioned drive system 1.

The drive module includes an input gear that is rotatable. The output module includes an output shaft 13. The shift module includes a first shift sleeve 30, a second shift sleeve 40, and a transmission gear 21. The input gear is connected to the output shaft 13 via the first shift sleeve 30, or the input gear is connected to the output shaft 13 via the first shift sleeve 30 and the second shift sleeve 40. The transmission gear 21 is loosely fitted onto the output shaft 13 and connected to the output shaft 13 via the second shift sleeve 40. The first shift sleeve 30 includes at least two shift teeth. The input gear is connected to one of the at least two shift teeth, the output shaft 13 is connected to the other of the at least two shift teeth, and the transmission gear 21 is connected to the third of the at least two shift teeth. Thus, both the first shift sleeve 30 and the second shift sleeve 40 can allow the power of the drive module 11 to be transmitted to the output shaft 13 through different paths, realizing the switching of different gears.
