[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0036] Reference below Figure 1-Figure 5 A drive system assembly 100 according to an embodiment of the present invention is described, and the present invention also provides a vehicle.

[0037] Reference Figure 1-Figure 5 As shown, the drive system assembly 100 of the embodiment of the present invention includes: a transmission 10 and a steering pump 20 .

[0038] The transmission 10 includes a first input shaft 11, a first output shaft 12, and a second output shaft 13. The first input shaft 11 can selectively connect to the first output shaft 12 and / or the second output shaft 13. That is, power is transmitted between the first input shaft 11 and the first output shaft 12 and / or the second output shaft 13. Specifically, the first input shaft 11 can transmit power transmitted by a power source to the first output shaft 12 and the second output shaft 13. The first output shaft 12 can output power transmitted by the first input shaft 11 or power transmitted by the power source, and the second output shaft 13 can output power. The power source connected to the first input shaft 11 can be the driving power of the vehicle, and the power source connected to the first output shaft 12 is the inertia power of the vehicle.

[0039] It can be understood that the driving power is the power that drives the vehicle forward. The first output shaft 12 is connected to the driving power output 71. The driving power output 71 means that the driving power is finally transmitted to the wheels to make the vehicle move forward. When the vehicle is braking or coasting, the driving power is not output, but the wheels still move forward. At this time, the inertia of the vehicle can be used as a power source, and the power is transmitted from the first output shaft 12 to the first input shaft 11 and the second output shaft 13.

[0040] The steering pump 20 is used to pump hydraulic oil to assist vehicle steering. The steering pump 20 is connected to the second output shaft 13, which drives the steering pump 20. In other words, the power source transmits power to the second output shaft 13 via the first input shaft 11 or the first output shaft 12. The second output shaft 13 then distributes part of the power to the steering pump 20, enabling the steering pump 20 to assist vehicle steering.

[0041] In this way, in addition to the function of driving power shifting, the transmission 10 can also provide power for accessories such as the steering pump 20 and the brake pump 30 without adding new parts. The drive system structure is more compact, the degree of integration is high, and the cost is reduced.

[0042] In some embodiments, accessories other than the steering pump 20 may also be powered through the transmission 10 .

[0043] Therefore, through the first input shaft 11, the first output shaft 12 and the second output shaft 13 of the transmission 10, the power of the power source can be distributed to accessories such as the steering pump 20, making the drive system structure more compact, highly integrated and cost-reduced.

[0044] Reference Figure 1-Figure 5 As shown, the first input shaft 11 is selectively connected to the second output shaft 13 via a first transmission mechanism. The first transmission mechanism includes a first gear set 14, a second gear set 15, and a first coupling sleeve 131. The first coupling sleeve 131 is disposed on the second output shaft 13 and can selectively engage at most one of the first gear set 14 and the second gear set 15. The first coupling sleeve 131 is slidably connected to the second output shaft 13 and can enable the second output shaft 13 to engage with the first gear set 14 or the second gear set 15. When the vehicle is in parking mode, driving mode, braking mode, or coasting mode, the first coupling sleeve 131 engages with the first gear set 14. When the vehicle is in reverse mode, the first coupling sleeve 131 engages with the second gear set 15. Regardless of whether the first coupling sleeve 131 engages with the first gear set 14 or the second gear set 15, power can be transmitted from the first input shaft 11 to the second output shaft 13.

[0045] Reference Figure 1-Figure 5As shown, the first gear set 14 includes a first gear 141 and a second gear 142. The first gear 141 is fixedly connected to the first input shaft 11 and rotates coaxially therewith. The second gear 142 meshes with the first gear 141 and is loosely mounted on the second output shaft 13. The first coupling sleeve 131 selectively connects the second gear 142 to the second output shaft 13. When the vehicle is in parking mode, driving mode, braking mode, or coasting mode, driving power is transmitted from the first input shaft 11, the first gear 141 rotates coaxially therewith, and the first gear 141 drives the second gear 142 to rotate. When the first coupling sleeve 131 is connected to the second gear 142 and the second output shaft 13, power can be distributed to the steering pump 20 via the second output shaft 13.

[0046] Reference Figure 1-Figure 5 As shown, the second gear set 15 includes a third gear 151, a fourth gear 152, and a fifth gear 153. The third gear 151 is fixedly connected to the first input shaft 11 and rotates coaxially. The fourth gear 152 is meshedly connected to the third gear 151 and the fifth gear 153 respectively. The fifth gear 153 is loosely mounted on the second output shaft 13. The first coupling sleeve 131 selectively connects the fifth gear 153 to the second output shaft 13. In the vehicle reverse mode, the first input shaft 11 rotates in the opposite direction. By adding a gear and externally meshing the third gear 151, the fourth gear 152, and the fifth gear 153, the direction of the fifth gear 153 is opposite to that of the fourth gear 152. Even if the first input shaft 11 rotates in the opposite direction, the direction of the second output shaft 13 remains unchanged, and the driving power can be distributed to the steering pump 20 via the second output shaft 13.

[0047] Reference Figure 1-Figure 5 As shown, the drive system assembly 100 further includes a brake pump 30 , which can be selectively connected to the second output shaft 13 , so that when connected to the second output shaft 13 , the brake pump 30 is driven to operate via the second output shaft 13 .

[0048] The brake pump 30 compresses the air into high-pressure gas and stores the gas in the gas tank. When the vehicle needs to brake, the high-pressure gas will push the control piston, thereby causing the brake shoe to expand and generate friction with the brake drum, thereby achieving the braking effect. Therefore, the air pressure in the gas tank affects the braking effect.

[0049] Specifically, the power source transmits power to the second output shaft 13 via the first input shaft 11 or the first output shaft 12. When the air tank pressure reaches a lower threshold, the second output shaft 13 engages with the brake pump 30, distributing some of the power to the brake pump 30, enabling the brake pump 30 to cooperate with the brake system to achieve braking. When the air tank pressure reaches an upper threshold, the power from the second output shaft 13 is not distributed to the brake pump 30.

[0050] In some embodiments, the transmission 10 may be used alone to distribute power to the steering pump 20 or the brake pump 30 .

[0051] Reference Figure 1-Figure 5 As shown, the brake pump 30 includes a second input shaft 31, and the drive system assembly 100 also includes a clutch 40. The clutch 40 is connected between the second output shaft 13 and the second input shaft 31. The second input shaft 31 can be selectively connected to the second output shaft 13 via the clutch 40. That is, depending on the air pressure in the air tank, the clutch 40 engages or disengages the second output shaft 13 and the second input shaft 31, thereby controlling whether the power transmitted to the second output shaft 13 is distributed to the brake pump 30. Specifically, when the air pressure in the air tank reaches a lower threshold, the clutch 40 engages the second output shaft 13 and the second input shaft 31, and the second output shaft 13 distributes part of its power to the brake pump 30, so that the brake pump 30 cooperates with the brake system to achieve braking. When the air pressure in the air tank reaches an upper threshold, the clutch 40 disengages the second output shaft 13 and the second input shaft 31, and the power of the second output shaft 13 is not distributed to the brake pump 30.

[0052] The clutch 40 may be an electromagnetic clutch 40 , and a clutch 40 may also be provided between the steering pump 20 and the second output shaft 13 to control whether the power of the second output shaft 13 is distributed to the steering pump 20 .

[0053] Reference Figure 1-Figure 5 As shown, the drive system assembly 100 further includes a drive motor 50, whose output shaft 51 is connected to the first input shaft 11. In this embodiment, drive power is provided by the drive motor 50. When the vehicle is in parking mode, driving mode, or braking or coasting mode, the drive motor 50 rotates forward, and the output shaft 51 of the drive motor 50 drives the first input shaft 11 to rotate forward, transmitting power to the first input shaft 11 in the transmission 10. In reverse mode, the drive motor 50 rotates reversely, and the output shaft 51 of the drive motor 50 drives the first input shaft 11 to rotate reversely, transmitting power to the transmission 10.

[0054] In some embodiments, the driving power of the vehicle can be provided jointly by the engine and the drive motor 50. When the engine and the drive motor 50 are coaxially connected in parallel, the engine is driven alone and the drive motor 50 rotates without being driven, or the engine and the drive motor 50 are driven at the same time, and the combined force of the two can be distributed to the steering pump 20 and the brake air pump 30.

[0055] Reference Figure 1-Figure 5As shown, the drive system assembly 100 also includes an intermediate shaft 60, which is drivingly connected to the first input shaft 11 and optionally drivingly connected to the first output shaft 12. The intermediate shaft 60 is drivingly connected to the first input shaft 11 via a sixth gear and a seventh gear 61. The sixth gear is fixedly connected to the first input shaft 11, and the seventh gear 61 is fixedly connected to the intermediate shaft 60. The sixth and seventh gears 61 mesh with each other. In other words, driving power can be transmitted through the first input shaft 11 and the intermediate shaft 60 to the first output shaft 12, and then to the driving power output 71, propelling the vehicle forward. Vehicle inertia can also be transmitted to the intermediate shaft 60 via the first output shaft 12.

[0056] Among them, the sixth gear can be the first gear 141, the third gear 151 or a new gear between the first transmission mechanism and the intermediate shaft. Regardless of whether the first input shaft 11 rotates forward or reverse, it can be engaged with the seventh gear 61 of the intermediate shaft 60 to meet different power transmission routes.

[0057] The intermediate shaft 60 is selectively connected to the first output shaft 12 via a second transmission mechanism. The second transmission mechanism includes a second coupling sleeve 121 and at least one third gear set 16. The second coupling sleeve 121 is disposed on the first output shaft 12. The two third gear sets 16 are also used to transmit power. Driving power can be transmitted from the intermediate shaft 60 to the third gear sets 16, and then to the first output shaft 12. Vehicle inertia can be transmitted from the first output shaft 12 to the third gear sets 16, and then to the intermediate shaft 60. The third gear sets 16 can amplify the driving power to drive the vehicle. Different third gear sets 16 have different transmission ratios, which can achieve different driving effects.

[0058] The second coupling sleeve 121 can selectively engage with at most one third gear set 16 . The transmission ratios of the plurality of third gear sets 16 are different. Different driving effects can be achieved by engaging the second coupling sleeve 121 with different third gear sets 16 .

[0059] Reference Figure 1-Figure 5 As shown, the third gear set 16 includes an eighth gear 161 and a ninth gear 162. The eighth gear 161 is fixedly connected to the intermediate shaft 60 and rotates coaxially. The ninth gear 162 meshes with the eighth gear 161 and is loosely mounted on the first output shaft 12. Thus, when driving power is transmitted, the sixth gear meshes with the seventh gear 61. The rotation of the intermediate shaft 60 synchronously drives the eighth gear 161, and the eighth gear 161 meshes with the ninth gear 162, transmitting power to the first output shaft 12. When vehicle inertia is the source of power, the power transmission process is reversed.

[0060] The second coupling sleeve 121 can selectively connect any ninth gear 162 to the first output shaft 12 , and different transmission ratios can be selected according to the required state of the vehicle to achieve different driving effects.

[0061] In summary, combined Figure 1-Figure 5 Table 1 describes the power transmission routes of different vehicle working modes.

[0062] Table 1

[0063]

[0064] Reference Figure 2 As shown in Table 1, in the vehicle's parking mode, the first coupling sleeve 131 is engaged with the first gear set 14, the second coupling sleeve 121 is in an intermediate state, and no driving power is output 71. Driving power is transmitted to the first input shaft 11, the first gear set 14, and the second output shaft 13. Depending on the vehicle's steering state and the air pressure in the air tank, the clutch 40 is selectively engaged or disengaged, and the second output shaft 13 distributes power to the steering pump 20 and the brake pump 30.

[0065] Reference Figure 3 As shown in Table 1, in the vehicle's driving mode, the first coupling sleeve 131 meshes with the first gear set 14, and the second coupling sleeve 121 meshes with one of the third gear sets 16, resulting in forward drive power output. The drive power is transmitted to the first input shaft 11. A portion of the power is transmitted to the intermediate shaft 60 via the seventh gear 61, and then to the first output shaft 12 via one of the third gear sets 16, ultimately output to the drive power output 71, driving the vehicle forward. The remaining power is transmitted to the second output shaft 13 via the first gear set 14. Depending on the vehicle's steering state and the air pressure in the air tank, the clutch 40 selectively disengages or engages, and the second output shaft 13 distributes the power to the steering pump 20 and the brake pump 30.

[0066] Reference Figure 4 As shown in Table 1, in braking or coasting mode, the first coupling sleeve 131 meshes with the first gear set 14, and the second coupling sleeve 121 meshes with one of the third gear sets 16. Vehicle inertia causes forward rotation and no drive power is generated. Vehicle inertia is transmitted through one of the third gear sets 16 on the first output shaft 12, and then via the intermediate shaft 60 to the first gear set 14. The first gear set 14 then transmits power to the second output shaft 13. Depending on the vehicle's steering state and the air tank pressure, the clutch 40 selectively engages or disengages, and the second output shaft 13 distributes power to the steering pump 20 and brake pump 30.

[0067] Reference Figure 5As shown in Table 1, in the vehicle's reverse mode, the first coupling sleeve 131 meshes with the second gear set 15, and the second coupling sleeve 121 meshes with one of the third gear sets 16, resulting in reverse output of the driving power. The driving power is transmitted to the first input shaft 11. A portion of the power is transmitted to the intermediate shaft 60 via the seventh gear 61, and then to the first output shaft 12 via one of the third gear sets 16, and finally output to the driving power output 71, driving the vehicle backward. The remaining power is transmitted to the second output shaft 13 via the second gear set 15. Depending on the vehicle's steering state and the air pressure in the air tank, the clutch 40 selectively disengages or engages, and the second output shaft 13 distributes the power to the steering pump 20 and the brake pump 30.

[0068] In addition, the drive system also includes a power battery 73, a motor controller 72 and an electronic control unit 74, which are used to coordinate the operation of the drive system. The specific control logic is as follows:

[0069] Vehicle parking mode: When there is a need to turn on the spot, the electronic control unit 74 detects that the steering wheel angle is greater than the threshold a, and controls the first coupling sleeve 131 to engage with the first gear set 14. If the air tank pressure is less than the lower limit threshold P1, the electronic control unit 74 controls the clutch 40 to engage. When the air pressure rises to be greater than the upper limit threshold P2, the electronic control unit 74 controls the electromagnetic clutch 40 to disengage. At this time, the second coupling sleeve 121 is in the middle state, and the driving power is not output, only the steering pump 20 or the brake air pump 30 is driven.

[0070] Vehicle Drive Mode: To ensure safety during driving, the steering pump 20 must operate continuously, and the brake pump 30 must operate in a time-sharing manner based on the air tank pressure. The electronic control unit 74 controls the first coupling sleeve 131 to engage with the first gear set 14. If the air tank pressure is less than the lower threshold value P1, the electronic control unit 74 controls the clutch 40 to engage. When the air pressure rises above the upper threshold value P2, the electronic control unit 74 controls the clutch 40 to disengage. At this time, the second coupling sleeve 121 engages with one of the third gear sets 16 according to the required gear position, driving the power output in the forward direction, driving the entire vehicle and driving the steering pump 20 or the brake pump 30.

[0071] Vehicle braking or coasting mode: To ensure safety during driving, the steering pump 20 must operate continuously, and the brake pump 30 must operate in a time-sharing manner based on the air tank pressure. The electronic control unit 74 controls the first coupling sleeve 131 to engage with the first gear set 14. If the air tank pressure is less than the lower threshold value P1, the electronic control unit 74 controls the clutch 40 to engage. When the air pressure rises above the upper threshold value P2, the electronic control unit 74 controls the clutch 40 to disengage. At this time, the second coupling sleeve 121 engages with one of the third gear sets 16 according to the required gear position. The power of the steering pump 20 or brake pump 30 is provided by the vehicle inertia. The drive motor 50 can now be in a state of energy recovery or idling with the vehicle's inertia.

[0072] Vehicle Reverse Mode: To ensure safety during driving, the steering pump 20 must operate continuously, and the brake pump 30 must operate in a time-sharing manner based on the air tank pressure. The electronic control unit 74 controls the first coupling sleeve 131 to mesh with the second gear set 15. If the air tank pressure is less than the lower threshold P1, the electronic control unit 74 controls the clutch 40 to engage. When the air pressure rises above the upper threshold P2, the electronic control unit 74 controls the clutch 40 to disengage. At this time, the second coupling sleeve 121 engages one of the third gear sets 16 according to the required gear position. The motor then reverses its drive, generating reverse power output, driving the vehicle and the steering pump 20 or brake pump 30.
