Description

Technical Field

[0001] The present application relates to the technical field of mechanical transmission, and in particular to a continuously variable transmission device. Background Art

[0002] Traditional transmissions, as key components in mechanical transmission systems, have long played a pivotal role in various industrial applications. However, with the advancement of technology and the continuous improvement of industrial standards, these traditional transmissions have gradually exposed some inherent limitations, especially in terms of the sense of frustration during gear shifting and the limitation of the speed range.

[0003] Gear shifting is a common phenomenon in most traditional transmission devices, mainly caused by the instantaneous power interruption or mutation when switching gears. This inconsistent speed shifting experience not only affects the operating efficiency of the equipment, but may also cause additional wear on the transmission system, thereby shortening the overall service life. In addition, the sense of frustration may also cause operational inconvenience. Even in some high-precision or high-sensitivity application scenarios, this unstable speed shifting characteristic may become a key factor limiting system performance.

[0004] On the other hand, the limited speed range is also a major shortcoming of traditional speed change devices. With the increasing demand for diversified and complex transmission in modern industry, the traditional limited speed range can no longer meet the speed change requirements of various mechanical equipment under different working conditions. This not only limits the scope of application of the equipment, but may also lead to reduced energy efficiency and increased costs in actual applications. Summary of the invention

DETAILED DESCRIPTION

[0030] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0031] A continuously variable transmission device according to an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 4 As shown, a continuously variable transmission device according to an embodiment of the present application may include a bearing 1, a center shaft 2, a cone 3, a torque adjustment mechanism 4, an electronic control system 5 and a transmission device 6, wherein the center shaft 2 may be movably disposed in the bearing 1.

[0033] It can be understood that the bearing 1 is the basic supporting component of the entire speed change device, and the bearing 1 ensures that the central shaft 2 can rotate smoothly and accurately. The central shaft 2 is the core transmission component of the speed change device. The central shaft 2 not only supports the cone 3 and the torque adjustment mechanism 4, but also transmits power through its rotation. Its design allows the cone 3 and the torque adjustment mechanism 4 to rotate and adjust around it.

[0034] The cone 3 is rotatably disposed on the central shaft 2 .

[0035] It is understandable that the cone 3 is rotatably disposed on the central shaft 2, and its unique cone design is the key to achieving stepless speed change. The side wall of the cone 3 is connected to the first transmission mechanism 61 and the second transmission mechanism 62. By adjusting the rotation angle of the cone 3, the transmission ratio of the transmission device 6 can be changed, thereby achieving stepless speed change.

[0036] The torque adjustment mechanism 4 is movably arranged on the central shaft 2 , and the torque adjustment mechanism 4 is movably connected to the inner wall of the cone 3 .

[0037] It is understandable that the torque adjustment mechanism 4 is movably arranged on the central shaft 2 and movably connected to the inner wall of the cone 3. The function of the torque adjustment mechanism 4 is to adjust the torque received by the cone 3, so as to achieve fine adjustment of the transmission ratio.

[0038] The electric control system 5 is connected to one end of the central shaft 2 .

[0039] It can be understood that the electronic control system 5 is connected to one end of the central shaft 2 and is the intelligent control center of the entire continuously variable transmission device.

[0040] The transfer device 6 includes a first transfer mechanism 61 and a second transfer mechanism 62 , wherein the first transfer mechanism 61 and the second transfer mechanism 62 are rotatably arranged on both sides of the cone 3 , and the first transfer mechanism 61 and the second transfer mechanism 62 are connected to the side walls of the cone 3 , respectively.

[0041] It can be understood that the transmission device 6 includes a first transmission mechanism 61 and a second transmission mechanism 62, which are rotatably disposed on both sides of the cone 3 and connected to the side walls of the cone 3. The transmission device 6 is responsible for transmitting power from the central shaft 2 to the external load. By changing the relative position or angle between the cone 3 and the first transmission mechanism 61 and the second transmission mechanism 62, stepless speed change can be achieved to meet different power transmission requirements.

[0042] Users can flexibly switch between automatic and manual control modes according to actual needs to accurately adjust the speed parameters.

[0043] In the automatic mode, the electronic control system 5 can intelligently adjust the transmission ratio of the transmission device according to the preset algorithm and parameters to adapt to different loads and working conditions. In the manual mode, the user can directly control the rotation of the central shaft 2 through simple operations to quickly achieve speed change.

[0044] Whether in automatic or manual mode, the transmission ratio of the transmission will change accordingly as long as the central shaft 2 is moved, and the torque will be adaptively adjusted. This design enables the transmission to respond quickly to changes in external loads and maintain stable output torque and speed, thereby performing well in various application scenarios.

[0045] In one embodiment of the present application, Figure 1 and Figure 3 As shown, the torque adjustment mechanism 4 includes a groove 41, two variable pull rods 42, two pulleys 43, two springs 44 and two spring clutches 45, wherein the groove 41 is arranged on the central shaft 2, the two variable pull rods 42 are respectively movably arranged at both ends in the groove 41, the two pulleys 43 are rotatably arranged on the two variable pull rods 42, one end of the two springs 44 is connected to the side wall of one end of the central shaft 2, and the other end is respectively connected to one end of the two variable pull rods 42, one end of the two spring clutches 45 is respectively connected to the other end of the two variable pull rods 42, and the other end is respectively connected to the other end of the central shaft 2.

[0046] It is understandable that the groove 41 is carefully arranged on the central shaft 2, and its shape and size are precisely calculated to ensure that the variable tie rod 42 can move smoothly and remain stable therein. The design of the groove 41 allows the variable tie rod 42 to have a certain range of movement in the axial direction, thereby achieving precise adjustment of the torque.

[0047] Two variable pull rods 42 are movably arranged at the two ends of the groove 41. The length of the variable pull rod 42 can be adjusted as needed, and this feature enables the torque adjustment mechanism 4 to flexibly adapt to different torque requirements. The design of the variable pull rod 42 also ensures a reliable connection with the pulley 43 and the spring clutch 45.

[0048] Two pulleys 43 are rotatably arranged on two variable rods 42. The main function of the pulleys 43 is to transmit torque and balance and adjust the tension in the system through their rotation. When the variable rod 42 moves, the pulleys 43 will change their positions accordingly, thereby changing the contact point with the cone 3 or other transmission components and the torque transmitted.

[0049] One end of the two springs 44 is connected to the side wall of one end of the central shaft 2, and the other end is connected to one end of the two variable rods 42. The springs 44 play a role of reset and buffering. When the variable rod 42 is moved by an external force, the springs 44 absorb and store energy, and then help the variable rod 42 return to the initial position after the external force disappears. This design helps to maintain the stability and reliability of the system.

[0050] One end of the two spring clutches 45 is connected to the other end of the two variable pull rods 42, and the other end is connected to the other end of the central shaft 2. The design of the spring clutch 45 allows flexible connection and disconnection with the central shaft 2 when the variable pull rod 42 moves. This flexible connection helps to reduce shock and vibration in the system while ensuring that torque can be transmitted smoothly. When the electronic control system 5 issues an instruction, the spring clutch 45 will adjust its connection state as needed to achieve precise control of the torque.

[0051] How it works

[0052] During the operation of the continuously variable transmission, the electronic control system 5 sends instructions to the torque adjustment mechanism 4 according to actual needs. When the torque needs to be adjusted, the electronic control system 5 controls the variable rod 42 to move in the groove 41. As the variable rod 42 moves, the pulley 43 changes the contact point with the cone 3 or other transmission components and the magnitude of the transmitted torque. At the same time, the spring 44 absorbs and stores energy, and then helps the variable rod 42 return to its initial position after the external force disappears. The spring clutch 45 adjusts its connection state according to the instructions of the electronic control system 5 to achieve precise control of the torque. During the whole process, the torque adjustment mechanism 4 can respond quickly to the instructions of the electronic control system 5 to ensure the smooth operation and precise control of the transmission.

[0053] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the first transmission mechanism 61 includes a second bearing 611, a power output shaft 612 and a plurality of transmission wheels 613, wherein the power output shaft 612 is rotatably disposed in the second bearing 611, the plurality of transmission wheels 613 are respectively rotatably disposed on the power output shaft 612, and the plurality of transmission wheels 613 are respectively rotatably connected to the side walls of the cone 3.

[0054] It can be understood that the second bearing 611 is a key component for supporting the power output shaft 612. It ensures that the power output shaft 612 can rotate smoothly and freely inside it while bearing the radial and axial loads from the transmission system.

[0055] The power output shaft 612 is a core component rotatably disposed in the second bearing 611. It is responsible for transmitting the rotational power of the cone 3 to an external load.

[0056] A plurality of transmission wheels 613 are rotatably disposed on the power output shaft 612, and they are key components for realizing power transmission. The design of the transmission wheels 613 needs to consider the contact mode and friction coefficient between the transmission wheels 613 and the side wall of the cone 3 to ensure the efficiency and stability of power transmission. At the same time, the number and distribution of the transmission wheels 613 need to be reasonably configured according to the rotation angle of the cone 3 and the range of transmission ratio to realize the function of stepless speed change.

[0057] The transmission wheel 613 and the side wall of the cone 3 are usually in contact with each other by rolling friction or sliding friction. In the rolling friction mode, the surface of the transmission wheel 613 may be equipped with rollers or needle rollers to reduce friction loss and improve transmission efficiency. In the sliding friction mode, the wear resistance and lubrication performance of the material of the transmission wheel 613 need to be considered to ensure long-term reliability.

[0058] How it works

[0059] During the operation of the continuously variable transmission, the rotational power of the cone 3 is transmitted to the power output shaft 612 through the contact between the cone 3 and the transmission wheel 613. As the rotation angle of the cone 3 changes, the position of the transmission wheel 613 on the power output shaft 612 will also be adjusted accordingly, thereby changing the transmission ratio. During this process, the second bearing 611 ensures that the power output shaft 612 can rotate smoothly and freely while bearing the load from the transmission system. The friction between the transmission wheel 613 and the side wall of the cone 3 efficiently transmits the rotational power to the power output shaft 612, thereby driving the external load. During the entire transmission process, the first transmission mechanism 61 can quickly respond to the rotation changes of the cone 3 to ensure the smooth operation and precise control of the transmission.

[0060] In one embodiment of the present application, Figure 4 As shown, the second transmission mechanism 62 includes a third bearing 621, a power transmission center shaft 622 and a sliding power transmission wheel 623, wherein the third bearing 621 is arranged parallel to the side wall of the cone 3, the power transmission center shaft 622 is rotatably arranged in the third bearing 621, and the sliding power transmission wheel 623 is slidably arranged on the power transmission center shaft 622.

[0061] It is understandable that the third bearing 621 is an important component supporting the power transmission central shaft 622, and is arranged parallel to the side wall of the cone 3. This parallel arrangement ensures that the power transmission central shaft 622 can rotate smoothly and freely inside it, while reducing friction and loss caused by angle deviation.

[0062] The power transmission center shaft 622 is a core component rotatably disposed in the third bearing 621, and is responsible for further transmitting the rotational power of the cone 3 to the sliding power transmission wheel 623, and finally transmitting it to the external load.

[0063] The sliding power transmission wheel 623 is a key component slidably arranged on the power transmission central shaft 622. It realizes the transmission of power by contacting with the side walls of the cone 3 or other transmission components.

[0064] The sliding adjustment of the sliding power transmission wheel 623 on the power transmission central shaft 622 is one of the keys to realize stepless speed change. By adjusting the position of the sliding power transmission wheel 623 on the shaft, the contact point and the transmission ratio between the sliding power transmission wheel 623 and the side wall of the cone 3 or other transmission parts can be changed, thereby realizing the function of stepless speed change.

[0065] How it works

[0066] During the operation of the continuously variable transmission device, the rotational power of the cone 3 is transmitted to the power transmission center shaft 622 through the contact between the cone 3 and the sliding power transmission wheel 623. As the rotation angle of the cone 3 changes, the position of the sliding power transmission wheel 623 on the power transmission center shaft 622 will also be adjusted accordingly, thereby changing the transmission ratio. During this process, the third bearing 621 ensures that the power transmission center shaft 622 can rotate smoothly and freely, while reducing the friction and loss caused by angle deviation. The friction between the sliding power transmission wheel 623 and the side wall of the cone 3 or other transmission parts efficiently transmits the rotational power to the power transmission center shaft 622, and finally transmits it to the external load. During the entire transmission process, the second transmission mechanism 62 can quickly respond to the rotation changes of the cone 3, and work in conjunction with the first transmission mechanism 61 to ensure the smooth operation and precise control of the transmission device.

[0067] In one embodiment of the present application, Figure 1-Figure 2 As shown, the cone 3 is divided into a plurality of rotatable small cones 31, and the outer side walls of the plurality of transmission wheels 613 are respectively a slide rail surface, a rubber surface, a friction surface and a gear surface, which are rotatably connected to the side walls of the plurality of small cones 31.

[0068] It is understandable that the small cone 31 can rotate relatively independently, thereby providing more delicate speed adjustment under different speed and torque requirements.

[0069] The multi-faceted design of the transmission wheel 613

[0070] The transmission wheel 613 is a key component for connecting the cone 3 and the power output shaft 612, and the design of its outer side wall is very important. The outer side wall of the transmission wheel 613 in this embodiment adopts a variety of different surface treatment methods to adapt to different side walls of the small cone 31 to ensure the efficiency and stability of power transmission.

[0071] Slide surface: This surface treatment method is mainly used to match the slide structure on the side wall of the small cone 31, and realize the transmission of power through sliding friction. The design of the slide surface reduces friction loss and improves transmission efficiency. The center axis matching wheel is a rigid guide wheel.

[0072] Rubber surface: The rubber surface has good elasticity and wear resistance, and can form a close fit with the side wall of the small cone 31 to ensure the stability of power transmission. At the same time, the friction coefficient of the rubber surface is moderate, which can transmit sufficient torque without damaging the transmission parts due to excessive friction. The center shaft matching wheel is a rubber guide wheel.

[0073] Friction surface: This surface treatment is mainly used in situations where high friction is required to transmit power. The friction surface is specially treated to increase the friction coefficient with the side wall of the small cone 31 to ensure the reliability of power transmission under high speed or high torque conditions. The center shaft matching wheel is a friction guide wheel.

[0074] Gear surface: The gear surface is mainly used to match the gear structure on the side wall of the small cone 31, and realize the transmission of power through gear meshing. The design of the gear surface improves the accuracy and stability of the transmission, and is suitable for occasions that require precise control of the transmission ratio. The center shaft matching wheel is a rigid guide wheel.

[0075] How it works

[0076] During the operation of the stepless speed change device, the plurality of small cones 31 rotate relatively independently according to actual needs, thereby changing the contact point and transmission ratio between the drive wheel 613. The outer wall of the drive wheel 613 adopts a corresponding surface treatment method according to the difference of the side walls of the small cones 31 to ensure the efficiency and stability of power transmission. As the small cones 31 rotate, the position of the drive wheel 613 on the power output shaft 612 will also be adjusted accordingly, thereby realizing the function of stepless speed change. During the entire speed change process, the cooperation between the cone 3 and the small cones 31 and the drive wheel 613 is tight and flexible, ensuring the smooth operation and precise control of the speed change device.

[0077] In one embodiment of the present application, Figure 2 and Figure 4 As shown, the sliding power transmission wheel 623 is rotatably connected to the side walls of multiple small cones 31 respectively.

[0078] It is understandable that the working principle

[0079] During the operation of the stepless speed change device, as the cone 3 rotates, each small cone 31 will adjust the rotation angle according to actual needs, thereby changing the contact point and transmission ratio with the sliding power transmission wheel 623. The sliding power transmission wheel 623 maintains good contact with the side wall of the small cone 31 by sliding adjustment thereon, ensuring the smooth and efficient transmission of power. In this process, the power transmission center shaft 622 serves as a supporting component to ensure that the sliding power transmission wheel 623 can rotate smoothly and freely, while reducing the friction and loss caused by angle deviation. During the entire speed change process, the sliding power transmission wheel 623 and the small cone 31 cooperate closely and flexibly, ensuring the smooth operation and precise control of the speed change device.
