Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle parts field, concretely relates to electric split drive type tooth pack and vehicle. BACKGROUND

[0002] The utility model discloses a main reduction assembly shell and main reduction assembly, namely discloses a tooth pack, the specific structure and principle of this existing patent are disclosed.

[0003] The tooth pack can be used on the front axle or rear axle of a vehicle (for example, a sand vehicle or an off-road vehicle), and the power of an engine is input to the tooth pack through an input shaft on the tooth pack, and the tooth pack then transmits the power to the front axle or rear axle of the vehicle. However, the input shaft of a conventional tooth pack does not have a power cut-off and transmission switching function, so that the vehicle does not have a four-wheel drive / two-wheel drive switching function.

[0004] At present, even if the input shaft has a power cut-off and transmission switching function, manual power cut-off and connection are still used, which is troublesome and laborious. UTILITY MODEL CONTENTS

[0005] The utility model intends to provide an electric split drive type tooth pack and vehicle to realize power input cut-off and power connection transmission switching in an electric manner.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electric split drive type tooth pack, comprising an input shaft, a synchronizing ring, an electric drive source, and a drive unit for moving the synchronizing ring; the electric drive source and the drive unit are connected, and the synchronizing ring is rotationally connected to the drive unit.

[0007] The input shaft comprises a first input shaft and a second input shaft for extending into the tooth pack shell, and the first input shaft and the second input shaft are coaxially arranged.

[0008] The synchronizing ring acts on both the first input shaft and the second input shaft at the same time, and the first input shaft and the second input shaft are power connected; the synchronizing ring only acts on one of the first input shaft and the second input shaft, and the first input shaft and the second input shaft are power transmission cut-off.

[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vehicle, comprising an engine and an electric split drive type tooth pack, the power of the engine is transmitted to the front axle of the vehicle on one hand, and the power of the engine is transmitted to the rear axle of the vehicle through the electric split drive type tooth pack on the other hand.

[0010] Alternatively, the power of the engine is transmitted to the rear axle of the vehicle on one hand, and the power of the engine is transmitted to the front axle of the vehicle through the electric split drive type tooth pack on the other hand.

[0011] The principle and advantages of this patented solution are as follows: The engine transmits power to the first input shaft, causing the first input shaft to rotate. The electric drive source drives the drive unit, providing power for its operation. The drive unit can move the synchronization ring. The movement of the synchronization ring controls whether it acts on only one of the first or second input shafts, or whether both input shafts act simultaneously.

[0012] When the synchronizer ring operates on only one of the first or second input shafts, there is no power transmission between them. The first input shaft will idle and will not transmit power to the second input shaft, so the second input shaft will not rotate, and therefore there is no power input to the dental assembly. When the synchronizer ring operates on either the first or second input shaft simultaneously, the first input shaft is connected to the second input shaft through the synchronizer ring. In this case, the first input shaft transmits power to the second input shaft, causing the second input shaft to rotate, and power input is received to the dental assembly.

[0013] Therefore, by controlling the movement of the synchronous ring, it is possible to control whether there is power input within the gearbox. The gearbox is installed on the front or rear axle of the vehicle. If the gearbox is installed on the rear axle, the engine power is transmitted to the front axle on one hand, and the engine power is transmitted to the rear axle via the electric drive gearbox on the other hand. When the engine is running, if there is no power transmission between the first and second input shafts, only the front axle wheels have rotational power, and the vehicle is in front-wheel drive mode. When there is power transmission between the first and second input shafts, both the front and rear axle wheels have rotational power, and the vehicle is in simultaneous front- and rear-wheel drive mode. If the gearbox is installed on the front axle, the engine power is transmitted to the rear axle on one hand, and the engine power is transmitted to the front axle via the electric drive gearbox on the other hand. When the engine is running, if there is no power transmission between the first and second input shafts, only the rear axle wheels have rotational power, and the vehicle is in rear-wheel drive mode. When there is power transmission between the first and second input shafts, both the front and rear axle wheels have rotational power, and the vehicle is in simultaneous front- and rear-wheel drive mode.

[0014] Therefore, this patented solution achieves vehicle drive mode switching by electrically controlling whether the dental pack receives power. Since power input to the dental pack is electrically controlled, no manual operation is required, making operation simple and convenient.

[0015] Preferably, as an improvement, the electric drive source is a motor or a solenoid valve.

[0016] Preferably, as an improvement, the drive unit includes a shift fork, on which a synchronizing ring is rotatably connected. Thus, by moving the shift fork, the shift fork drives the synchronizing ring to move. Since the synchronizing ring is rotatably mounted on the shift fork, the shift fork does not affect the rotation of the synchronizing ring.

[0017] Preferably, as an improvement, the drive unit includes a gear and a rack, the gear being connected to an electric drive source, the gear and rack meshing, and the rack being arranged parallel to the first input shaft. Thus, the electric drive source drives the gear to rotate, the gear drives the rack to move, and the rack ultimately drives the synchronizing ring to move. By changing the direction of gear rotation, the direction of rack movement is changed, thereby changing the direction of synchronizing ring movement.

[0018] Preferably, as an improvement, the drive unit includes a shift fork, with a synchronizing ring rotatably connected to the shift fork; a rack is connected to the shift fork. Thus, movement of the rack drives movement of the shift fork, and the shift fork drives movement of the synchronizing ring.

[0019] Preferably, as an improvement, the drive unit includes a guide member, on which the rack is slidably connected. The guide member limits and guides the movement of the rack, preventing it from separating from the gear and ensuring stable rack movement.

[0020] Preferably, as an improvement, the rack has a sliding hole into which a guide is inserted. The guide, inserted into the sliding hole, limits the position of the rack, ensuring it can only slide along the guide and will not move in other directions and separate from the gear.

[0021] Preferably, as an improvement, a protective shell is provided on the outer side of the first input shaft, and a first receiving space is provided on the protective shell for the first input shaft to pass through. A second receiving space is provided on the side of the protective shell, and an electric drive source is installed on the side of the protective shell, with the drive unit located in the second receiving space.

[0022] The protective shell is used to enclose and protect the first input shaft and the drive unit. The first accommodating space is used to accommodate the first input shaft, and the second accommodating space is used to accommodate the drive unit.

[0023] Preferably, as an improvement, the protective shell is provided with positioning holes for fixing the guide member, and the guide member is inserted into the positioning holes. Thus, by inserting the guide member into the positioning holes, the positioning of the guide member is achieved. Attached Figure Description

[0030] The basic implementation examples are as follows: Figures 1-4 The diagram shows an electrically driven dental assembly, comprising a housing 1, an input shaft, a synchronizing ring 10, an electric drive source 2, and a drive unit for moving the synchronizing ring 10. The input shaft includes a first input shaft 19 and a second input shaft 20. The first input shaft 19 is located outside the housing 1, and one end of the second input shaft 20 extends into the housing 1, while the other end is located outside the housing 1. The second input shaft 20 is used to input power into the housing 1. The housing 1 contains, but is not limited to, components such as pelvic teeth, an internal rotating body, two planetary teeth, and two half-shaft teeth. These components and their connections are clearly described in the existing patent CN221323227U and are not part of the invention of this application; therefore, they will not be elaborated upon in this embodiment.

[0031] In this embodiment, a protective shell 3 is fixed to the end of the dental casing 1 by a first bolt 12. The protective shell 3 has a first receiving space 17 for the first input shaft 19 to pass through. The first input shaft 19 and the second input shaft 20 are coaxially aligned, with the end of the first input shaft 19 located outside the protective shell 3. A connecting disc 4 is connected to the end of the first input shaft 19 located within the protective shell 3. A bearing 8 is provided between the first input shaft 19 and the first receiving space 17 of the protective shell 3, providing support for the first input shaft 19 and enabling its smooth rotation. An oil seal 9 is provided between the first input shaft 19 and the first receiving space 17 of the protective shell 3, providing a seal and reducing oil leakage within the protective shell 3.

[0032] In this embodiment, the electric drive source 2 is connected to the drive unit, and the synchronization ring 10 is rotatably connected to the drive unit.

[0033] Specifically, the electric drive source 2 is a motor or a solenoid valve. The protective shell 3 has a second receiving space 18 on its side. The electric drive source 2 is installed on the side of the protective shell 3 by a second bolt 14 (the side of the protective shell 3 has a bolt connection part 15 for connecting with the second bolt 14). The electric drive source 2 covers the opening of the second receiving space 18, and the drive unit is located in the second receiving space 18.

[0034] The drive unit in this embodiment includes a shift fork 11, a gear 5, and a rack 6. The gear 5 is coaxially and fixedly connected to the output shaft of the electric drive source 2. The gear 5 and the rack 6 mesh, and the rack 6 is connected to the shift fork 11 (e.g., integrally connected, fixed with screws, or welded). The outer side of the synchronization ring 10 is provided with an annular groove, and the shift fork 11 is located in the annular groove, thereby realizing the rotatable connection of the synchronization ring 10 to the shift fork 11. The rack 6 and the first input shaft 19 are arranged in parallel. In this way, the electric drive source 2 drives the gear 5 to rotate, the gear 5 drives the rack 6 to move, the rack 6 drives the shift fork 11 to move, and the shift fork 11 drives the synchronization ring 10 to move. By changing the rotation direction of the gear 5, the movement direction of the rack 6 is changed, thereby changing the movement direction of the shift fork 11.

[0035] The driving unit in this embodiment may further include a guide member 7, which is a guide post, and the rack 6 is slidably connected to the guide member 7. Specifically, the rack 6 has a sliding hole along its length, and the guide member 7 is inserted into the sliding hole. Figure 4 As shown, the second receiving space 18 of the protective shell 3 is provided with a positioning hole 16, which extends upward to the top of the protective shell 3. This allows the guide member 7 to be inserted downward into the positioning hole 16 through the top of the protective shell 3, thus connecting the guide member 7 to the protective shell 3 and fixing the guide member 7. A fixing screw 13 is provided at the top of the protective shell 3 to seal the positioning hole 16, thereby preventing the guide member 7 from slipping out of the positioning hole 16 and falling out.

[0036] In this embodiment, the first input shaft 19 has a first meshing tooth on its end circumferential side surface, the second input shaft 20 has a second meshing tooth on its end circumferential side surface, the synchronizing ring 10 is sleeved on the first input shaft 19, the synchronizing ring 10 has an inner tooth, the inner tooth meshes with the first meshing tooth, and the inner tooth can also mesh with the second meshing tooth.

[0037] Thus, when the synchronizing ring 10 acts on the first input shaft 19 and the second input shaft 20 simultaneously, the internal teeth mesh on the first meshing tooth and the second meshing tooth at the same time, and the first input shaft 19 and the second input shaft 20 are connected by power; when the synchronizing ring 10 acts only on the first input shaft 19 (or the second input shaft 20), the internal teeth mesh only on the first meshing tooth (or the second meshing tooth), and the power transmission between the first input shaft 19 and the second input shaft 20 is cut off.

[0038] The toothed axle in this embodiment is applied to vehicles, such as ATVs, off-road vehicles, and go-karts, specifically to the rear axle. The vehicle's engine power is transmitted to the front axle, supplying power to the front wheels, and simultaneously to the first input shaft 19, which in turn transmits power to the rear axle via the electric drive toothed axle, supplying power to the rear wheels.

[0039] When the synchronizing ring 10 operates on only one of the input shafts, the first input shaft 19 or the second input shaft 20, there is no power transmission between them. The first input shaft 19 will remain idle and will not transmit power to the second input shaft 20. Therefore, the second input shaft 20 will not rotate, and there is no power input to the dental assembly. When the synchronizing ring 10 operates on both the first input shaft 19 and the second input shaft 20 simultaneously, the first input shaft 19 is connected to the second input shaft 20 via the synchronizing ring 10. In this case, the first input shaft 19 transmits power to the second input shaft 20, causing it to rotate, and power is input to the dental assembly.

[0040] Therefore, in actual vehicle use, switching between four-wheel drive and two-wheel drive can be achieved. Specifically, when two-wheel drive is required, the electric drive source 2 drives the gear 5 to rotate, the gear 5 drives the rack 6 to move, the rack 6 drives the shift fork 11 to move, the shift fork 11 drives the synchronizer ring 10 to move, and the synchronizer ring 10 moves onto the first input shaft 19. The internal teeth of the synchronizer ring 10 are not engaged with the second meshing teeth. At this time, the first input shaft 19 rotates freely, the second input shaft 20 does not rotate, the gearbox has no power, so the rear wheels at the rear axle of the vehicle have no power output, only the front axle wheels of the vehicle have rotational power, and the vehicle is driven in a two-wheel drive mode.

[0041] When four-wheel drive is required, the electric drive source 2 drives the gear 5 to rotate, the gear 5 drives the rack 6 to move in the opposite direction, the rack 6 drives the shift fork 11 to move, the shift fork 11 drives the synchronizer ring 10 to move, and the synchronizer ring 10 moves towards the second input shaft 20. The internal teeth of the synchronizer ring 10 simultaneously mesh with the first meshing tooth and the second meshing tooth. At this time, the first input shaft 19 and the second input shaft 20 are connected together through the synchronizer ring 10. The engine inputs power to the first input shaft 19, the first input shaft 19 transmits power to the second input shaft 20, and there is power input in the gearbox. The gearbox finally transmits power to the rear axle wheels. At this time, both the front and rear axle wheels of the vehicle have rotational power, and the vehicle is in four-wheel drive mode.

[0042] Of course, in other embodiments, the driveshaft can also be mounted on the front axle of the vehicle. In this case, the engine's power is transmitted to the rear axle, and the engine's power is transmitted to the front axle via the electric driveshaft. Similarly, when the engine is running, if there is no power transmission from the first input shaft 19 and the second input shaft 20, only the rear axle wheels of the vehicle have rotational power, and the vehicle is rear-wheel drive. When there is power transmission from the first input shaft 19 and the second input shaft 20, both the front and rear axle wheels of the vehicle have rotational power, and the vehicle is simultaneously driven by both front and rear axles.

[0043] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
