DETAILED DESCRIPTION

[0031] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] like Figure 1 - Figure 8 As shown, the bidirectional transmission for a two-wheeled vehicle provided in this embodiment includes a main shaft 1, a sun gear 2 is rotatably connected to the main shaft 1 through a bearing, a planet carrier 3 is provided on the outside of the sun gear 2, a ring gear 4 is provided on the outside of the planet carrier 3, a hub 5 is provided on the outside of the ring gear 4, a primary clutch 6 is provided between the hub 5 and the ring gear 4, and a ratchet groove 7 is provided at one end of the planet carrier 3, an adjustment assembly 8 is provided on one side of the ratchet groove 7, and the other side of the adjustment assembly 8 corresponds to the sun gear 2, an end cover 9 is provided on the side of the sun gear 2 away from the adjustment assembly 8, the end cover 9 is fixedly connected to the hub 5 by bolts, and a secondary clutch 10 is provided between the end cover 9 and the hub 5;

[0033] The adjusting component 8 includes a pawl seat 801, which is fixedly mounted on the main shaft 1, and has two slots 802 on the pawl seat 801, and a pawl 803 is provided inside the slot 802, and the pawl 803 corresponds to the ratchet groove 7, and the upper ends of the two pawls 803 are fixedly connected with a pawl ring 804, and the end of the pawl ring 804 away from the pawl 803 is fixedly connected with a rotating plug 805, and the rotating plug 805 is fixedly connected with a cable locking piece 806. The main shaft 1 cooperates with the ring gear 4, the primary clutch 6 and the hub 5 to form a transmission structure to achieve power output, and then drives the pull wire on the cable locking piece 806 to drive the pull wire. The rotary plug 805 rotates, thereby causing the pawl ring 804 to drive the pawl 803 to move. Different power input paths can be achieved through the cooperation and separation of the pawl 803 and the ratchet groove 7. When the pawl 803 is embedded in the ratchet groove 7, the power transmission path in the planetary structure can be changed through the mutual cooperation of the planetary carrier 3, the sun gear 2, the end cover 9 and the secondary clutch 10, thereby achieving different transmission ratios. This allows the driver to adjust the power input path and input speed of the two-wheeled vehicle according to the actual riding situation, thereby improving riding comfort, controllability and overall vehicle performance, so that the driver can better adapt to various road conditions and riding needs.

[0034] Further, such as Figure 1 - Figure 8 As shown, the inner side of the pawl ring 804 is fixedly connected to the bearing seat 11, the bearing seat 11 is fixedly connected to the main shaft 1, and a return spring 12 is provided on the bearing seat 11, one end of the return spring 12 is connected to the bearing seat 11, and the other end of the return spring 12 is connected to the pawl ring 804. When the pawl ring 804 drives the pawl 803 to move to realize the change of the power input path by pulling the wire, the return spring 12 can quickly restore the pawl ring 804 to the initial position or the appropriate standby position, so that the pawl 803 can accurately cooperate with the ratchet groove 7 after the power input path is changed next time, thereby ensuring the smoothness and timeliness of the two-wheeled vehicle in the process of switching between different power input paths;

[0035] Among them, such as Figure 1 - Figure 8As shown, the end of the ring gear 4 close to the rotating plug 805 is fixedly connected to the flywheel 13, the outer side of the primary clutch 6 is connected to the hub 5, and the inner side of the primary clutch 6 is connected to the ring gear 4, the end cover 9 is rotatably connected to the main shaft 1 through a bearing, the outer side of the secondary clutch 10 is connected to the end cover 9, and the inner side of the secondary clutch 10 is connected to the sun gear 2, the planetary carrier 3 corresponds to the end cover 9, and the end of the planetary carrier 3 close to the end cover 9 is connected to the sun gear 2 through a bearing, the outer side of the end cover 9 is connected to the disc 14, and the disc 14 is provided with an oil brake 15. The flywheel 13 can store and release energy while the vehicle is running, improve power utilization efficiency, and enhance The vehicle operates efficiently and adapts to different riding conditions; through the primary clutch 6, the power transmission between the ring gear 4 and the hub 5 can be controlled as needed to achieve different transmission states; and the end cover 9 not only plays a sealing and supporting role, but the secondary clutch 10 inside it can regulate the power connection and separation between the sun gear 2 and other components; the disc 14 and the oil brake 15 outside the end cover 9 form a braking system, which can apply braking force to the disc 14 through the oil brake 15 when necessary to slow down or stop the vehicle and ensure driving safety, thereby realizing the power transmission, speed control and safe braking functions of the two-wheeled vehicle, meeting the needs of the two-wheeled vehicle under various driving conditions;

[0036] Furthermore, if Figure 1 As shown, the planet carrier 3 is fixedly connected to a plurality of evenly distributed planetary gears 16 via a rotating shaft. The plurality of planetary gears 16 are all meshed with the outer teeth on the sun gear 2, and the ends of the plurality of planetary gears 16 away from the sun gear 2 are meshed with the inner teeth of the ring gear 4. The meshing of the planetary gears 16 with the outer teeth of the sun gear 2 and the inner teeth of the ring gear 4 can transmit power and adjust the speed, thereby transmitting the power of the sun gear 2 to the ring gear 4. At the same time, by changing the relative motion relationship between the planet carrier 3, the sun gear 2 and the ring gear 4, different transmission ratios are achieved, thereby enabling the two-wheeled vehicle to obtain different speeds, meeting the power and speed requirements under various driving conditions, and improving the power performance and adaptability of the two-wheeled vehicle.

[0037] Furthermore, both ends of the main shaft 1 are threadedly connected with fastening nuts 17. Through the threaded connection, the fastening nuts 17 can tightly fix the components connected to the main shaft 1 on the main shaft 1 to prevent these components from loosening or displacement during the operation of the two-wheeled vehicle, ensure the stable connection between the components of the two-way transmission, and ensure the normal operation of the transmission.

[0038] like Figure 1 - Figure 8 As shown, the principle of a two-wheeled vehicle bidirectional transmission provided in this embodiment is as follows:

[0039] When the two-wheeled vehicle moves forward, the flywheel 13 rotates in the forward direction, and when the two-wheeled vehicle moves backward, the flywheel 13 rotates in the reverse direction. When the flywheel 13 rotates forward, the flywheel 13 cooperates with the ring gear 4, the primary clutch 6 and the hub 5 through the main shaft 1 to form a transmission structure to realize power output, and the two-wheeled vehicle moves forward. By pulling the cable on the cable locking member 806, the rotating plug 805 is driven to rotate, so that the pawl ring 804 drives the pawl 803 to move. At this time, the pawl 803 is embedded in the ratchet groove 7, driving the flywheel 13 to rotate in the reverse direction. The flywheel 13 drives the planetary carrier 3 to rotate through the main shaft 1, and then drives the sun gear 2, the end cover 9 and the secondary clutch 10 through several planetary gears 16 to drive the hub 5 to rotate, realizing power output, and the two-wheeled vehicle moves forward. In addition, the driver can adjust the power input path and input speed of the two-wheeled vehicle according to the actual riding situation, thereby improving the riding comfort, controllability and overall performance of the vehicle, so that the driver can better adapt to various road conditions and riding needs.

[0040] When the flywheel 13 is running in the forward direction, power can be input through the ring gear 4 and output from the sun gear 2. The sun gear 2 rotates in the reverse direction relative to the ring gear 4. At this time, although the planetary structure can achieve speed change, it cannot output power from the secondary clutch 10. Therefore, the power input from the flywheel 13 is output from the first-stage clutch 6 to the hub 5 through the ring gear, and the transmission ratio is 1:1.

[0041] When the flywheel 13 reverses, power can be input through the ring gear 4 and output through the sun gear 2. At this time, the sun gear 2 reverses relative to the ring gear 4 (at this time it rotates forward relative to the tire), and power is output from the secondary clutch 10 to the hub 5, with a transmission ratio of 1:1.29.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
