Description

Technical Field

[0001] This utility model relates to the field of motorcycle transmissions, specifically to continuously variable transmissions (CVTs) and motorcycles. Background Technology

[0002] A continuously variable transmission (CVT) is an automatic transmission system that can continuously change the gear ratio. Its core feature is that it does not require fixed gears; instead, it achieves smooth acceleration and deceleration by adjusting the contact radius of the drive belt or chain. This type of transmission is widely used in automobiles, motorcycles, and other vehicles, offering advantages such as simple structure, small size, good fuel economy, and high driving comfort.

[0003] In existing scooter motorcycles, the continuously variable transmission (CVT) is mounted on the outside of the motorcycle body and connected to the engine crankshaft on the inside of the motorcycle body. The CVT includes a drive wheel and a driven wheel, which are connected by a transmission belt. The drive wheel's shaft is connected to the crankshaft. The drive wheel consists of two cone discs. The outer cone disc is fixed, while the inner cone disc can slide back and forth on the shaft. In the prior art, the inner cone disc is often set as a pulley. The driven wheel also consists of two cone discs, and a clutch is provided between the cone disc on one side of the driven wheel and its shaft.

[0004] However, the existing variator structure mainly relies on the centrifugal force during rotation to adjust the gap between the cones on both sides of the drive wheel by squeezing the cones inside the drive wheel with the variator balls. The inclined housing and the variator balls squeeze the sliding cones to move the cones. During this process, there is a lot of friction between the variator balls and the housing and cones. Long-term use will cause severe wear and eventually lead to failure. Therefore, it requires frequent maintenance. However, since the continuously variable transmission mechanism is connected to the crankshaft of the engine or power structure inside the vehicle body, and the variator is located between the drive wheel and the inside of the vehicle body, disassembly and installation are relatively complicated. Utility Model Content

[0005] The present invention aims to provide a continuously variable transmission (CVT) and a motorcycle to solve the problems of severe wear and cumbersome disassembly and maintenance of the CVT mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a continuously variable transmission (CVT), comprising a CVT mechanism and an actuator mounted on the outside of the CVT mechanism, wherein the drive wheel is coaxially connected to the crankshaft, the inner cone of the drive wheel near the vehicle body is coaxially fixed to the crankshaft, and the outer cone is slidably disposed relative to the crankshaft, and the actuator comprises a mounting bracket for fixed connection with the CVT mechanism, a coaxial sliding structure disposed on the mounting bracket, and a drive structure for driving the coaxial sliding structure, wherein the coaxial sliding structure is used to coaxially push the outer cone of the drive wheel to slide on the crankshaft.

[0007] The beneficial effects of this solution are as follows: by inverting the cone discs on both sides of the drive wheel, the cone discs on both sides of the driven wheel also need to be inverted. At this time, the actuator only needs to be installed on the side of the continuously variable transmission mechanism away from the vehicle body, that is, connected to the outside of the vehicle body. When the product is damaged or aged and needs to be replaced or repaired, it is not necessary to completely disassemble the continuously variable transmission mechanism, which reduces the amount of manual labor and also reduces the maintenance costs for consumers.

[0008] In existing technologies, the drive wheel is connected to the crankshaft, and the cone disc inside the drive wheel is set as a jacking disc. The jacking disc slides through the centrifugal force of the jacking balls and the friction between the jacking balls and the housing, which pressurizes the cone disc. This transmission efficiency is relatively low. In addition, jacking disc continuously variable transmission systems are usually used in small-displacement vehicles, which has a narrow range of applications. Compared with existing technologies, in this solution, the actuator is mounted on the outside of the continuously variable transmission mechanism. It is connected to the slidable cone disc on the outside of the drive wheel through a coaxial sliding structure, and the coaxial sliding of the outer cone disc is achieved through the drive structure. Therefore, the drive of the transmission system and the drive of the engine are completely separated, which can effectively reduce additional fuel consumption and is more suitable for motorcycles with high torque and high output performance.

[0009] Furthermore, for manufacturers, the continuously variable transmissions (CVTs) they produce are mass-produced, comprising both the CVT structure and the actuator structure—two complete components. Therefore, consumers or operators can directly purchase and assemble both components in bulk for resale. This increases sales volume and allows manufacturers to raise prices, while for operators, it reduces the number of wholesalers and associated fees and procedures, making it a beneficial product for the market. For users, the reduced maintenance costs are also a benefit, thus playing a positive role in promoting the overall market.

[0010] On the other hand, for the continuously variable transmission (CVT) systems involved in the existing technology that have already been mass-produced, since the mass-produced CVT systems are centrally stored in preparation for the next production, there is usually a large inventory of the produced transmission systems. The actuator of this solution can be adapted to the large number of existing CVT systems. If the operator has demand, it can be installed and sold in batches. It only needs to purchase the compatible model actuator from the manufacturer separately, remove the pulley and put it into production of other models, install the cone discs on both sides of the drive wheel and driven wheel in reverse, and then install the actuator on the outside of the CVT system.

[0011] Furthermore, the continuously variable transmission (CVT) includes a housing fixedly connected to the vehicle body, and a driven shaft rotatably connected inside the housing. The driven wheel is coaxially disposed on the driven shaft. The drive wheel includes a primary moving cone disc and a primary fixed cone disc, and the driven wheel includes a secondary moving cone disc and a secondary fixed cone disc. The primary fixed cone disc and the primary moving cone disc are located on the inner and outer sides of the crankshaft near the vehicle body, respectively.

[0012] Furthermore, the coaxial sliding structure includes a guide cylinder formed on the mounting bracket, the guide cylinder being coaxially formed with the crankshaft, and a release bearing slidably connected to the outer ring of the guide cylinder near the housing. The drive structure is connected to the release bearing and is used to drive the release bearing against the drive wheel.

[0013] The beneficial effects of this solution are as follows: the inner ring of the release bearing is slidably connected to the guide cylinder, and the outer ring is pressed against the primary moving cone disk under the pressure of the drive structure. After the primary moving cone disk comes into contact with the release bearing, the primary moving cone disk drives the primary moving cone disk to rotate coaxially through dynamic friction. There is no relative motion between the two, so there is no wear and the service life is long.

[0014] Furthermore, the diameter of the guide tube is larger than the diameter of the crankshaft, and the guide tube is for the crankshaft to pass through.

[0015] The beneficial effects of this solution are as follows: the guide cylinder provides support for the release bearing without interfering with the rotation of the crankshaft. The two do not come into contact, and for installation, disassembly, and replacement, the engine system and the transmission system are completely separated and do not interfere with each other, further ensuring improved replacement and maintenance efficiency and reduced maintenance costs.

[0016] Furthermore, the drive structure includes a drive cavity axially opened at the end of the guide cylinder away from the housing, a first piston being slidably connected between the end of the drive cavity near the housing and the outer ring of the guide cylinder, and a drive cylinder communicating with the drive cavity. Fluid is disposed in the drive cylinder and the drive cavity, and a drive component is installed in the drive cylinder. The drive component is used to drive the first piston against the release bearing through the fluid, thereby causing the release bearing to abut against the drive wheel.

[0017] Furthermore, the fluid is hydraulic oil, the driving component is a motor, a second piston is slidably connected inside the driving cylinder, and a lead screw is coaxially mounted on the output end of the motor, with the lead screw threadedly connected to the second piston.

[0018] The beneficial effects of this solution are as follows: the motor drives the second piston to push the hydraulic oil to the drive chamber and push the first piston to slide. Compared with the prior art, the force loss of hydraulic drive is smaller, and there is no oil consumption caused by speed change, which further improves the transmission efficiency.

[0019] Furthermore, the mounting bracket is also equipped with a sensing system, which includes a resistor fixed to the mounting bracket and coaxially arranged with the guide cylinder, and a sensor connected to the resistor. The resistor is slidably arranged relative to the release bearing, and the sensor circuit voltage change detects the displacement of the release bearing.

[0020] The beneficial effects of this solution are as follows: whether the primary moving cone is advancing or retreating, the sensor can measure the voltage change through the resistive element, convert it into a corresponding value, and send it to the TCU for processing, thereby improving the controllability and flexibility of speed regulation.

[0021] Furthermore, a first elastic element is provided between the secondary moving cone disk and the housing, and the clutch includes a brake hub fixed to the housing and a brake shoe hinged to the secondary moving cone disk, with a second elastic element connecting the brake shoe and the secondary moving cone disk.

[0022] Furthermore, a third elastic element is provided between the mounting bracket and the release bearing, and a fourth elastic element is provided between the second piston and the drive cylinder.

[0030] The reference numerals in the accompanying drawings include: actuator 1, mounting bracket 11, third elastic element 111, coaxial sliding structure 12, drive structure 13, guide cylinder 14, release bearing 141, drive ring 142, drive cavity 15, first piston 151, drive cylinder 131, second piston 1311, fourth elastic element 1312, motor 132, lead screw 1321, sensing system 2, resistive element 21, sensor 22, displacement slider 23, continuously variable transmission mechanism 3, housing 31, crankshaft 311, driven shaft 312, drive wheel 4, primary moving cone disk 41, primary fixed cone disk 42, driven wheel 5, secondary moving cone disk 51, first elastic element 511, secondary fixed cone disk 52, brake disc 53, brake shoe 54.

[0031] Example

[0032] The basic implementation examples are as follows: Figure 1-5 As shown, Figures 1-2The continuously variable transmission (CVT) shown includes a CVT mechanism 3 for connection to the vehicle body. The CVT mechanism 3 includes a housing 31 fixedly connected to the vehicle body. A crankshaft 311 and a driven shaft 312 are rotatably mounted at both ends of the housing 31. A drive wheel 4 and a driven wheel 5 are coaxially mounted on the crankshaft 311 and the driven shaft 312, respectively. A transmission belt drives the drive wheel 4 and the driven wheel 5. The drive wheel 4 includes an inner primary fixed cone disc 42 close to the vehicle body and an outer primary moving cone disc 41 away from the vehicle body. The primary fixed cone disc 42 is coaxially fixed to the crankshaft 311, and the primary moving cone disc 41 is coaxially slidably connected to the crankshaft 311. A sleeve is coaxially fixedly welded to the primary moving cone disc 41. The inner circle of the sleeve has the same diameter as the cross-sectional circle of the crankshaft 311. The crankshaft 311 and the inner circle of the sleeve are axially slidably connected through a groove and an axial slider, thereby achieving a sliding connection between the primary moving cone disc 41 and the crankshaft 311.

[0033] like Figures 2-3 As shown, it also includes an actuator 1 mounted on the outer side of the housing 31. The actuator 1 includes a mounting bracket 11 for fixed connection with the housing 31. The mounting bracket 11 is fixedly connected to the housing 31 by bolts. The actuator 1 also includes a coaxial sliding structure 12 disposed on the mounting bracket 11. The coaxial sliding structure 12 includes a guide cylinder 14 fixedly disposed on the mounting bracket 11. The guide cylinder 14 is located on the side of the mounting bracket 11 closer to the housing 31, and the inner diameter of the guide cylinder 14 is larger than the diameter of the crankshaft 311. The mounting bracket 11 When installed in housing 31, the guide cylinder 14 is for the end of crankshaft 311 inside housing 31 to pass through. Neither the guide cylinder 14 nor the mounting bracket 11 is in contact with crankshaft 311. The coaxial sliding structure 12 also includes a release bearing 141 that is slidably connected to the end of guide cylinder 14 near the end of primary moving cone 41. The inner ring cross-sectional diameter of release bearing 141 is equal to the outer ring cross-sectional diameter of guide cylinder 14. A groove and slider structure are also provided between the outer ring of guide cylinder 14 and the inner ring of release bearing 141 to realize the sliding connection between release bearing 141 and guide cylinder 14.

[0034] like Figures 2-5As shown, the actuator 1 also includes a drive structure 13 connected to the mounting bracket 11 and used to drive the release bearing 141 to slide on the guide cylinder 14. The drive structure 13 includes a drive cavity 15 axially formed on the outer ring of the guide cylinder 14. The drive cavity 15 is located at the end of the guide cylinder 14 away from the housing 31. The drive cavity 15 is configured as an annular space coaxial with the guide cylinder 14. A first piston 151 is slidably connected between the drive cavity 15 and the outer wall of the guide cylinder 14. The first piston 151 is annular and embedded in the annular space of the drive cavity 15. The top of the drive cavity 15 forms a sealed space through the first piston 151. A drive ring 142 is also slidably connected to the outer ring of the guide cylinder 14. The drive ring 142 is fixedly connected to the release bearing 141. A third elastic element 111 is connected between the drive ring 142 and the mounting bracket 11. The third elastic element 111 is set as a tension spring. Under normal circumstances, the third elastic element 111 pulls the release bearing 141 away from the housing 31 through the drive ring 142. The inner ring of the drive ring 142 and the outer ring of the guide cylinder 14 have the same cross-sectional diameter. A sliding groove and a slider structure are also provided between the inner wall of the drive ring 142 and the outer wall of the guide cylinder 14, so as to realize the sliding connection between the drive ring 142 and the guide cylinder 14. The radial thickness of the drive ring 142 along the guide cylinder 14 is not greater than the radial thickness of the drive cavity 15 along the guide cylinder 14.

[0035] like Figures 2-5 As shown, the drive structure 13 also includes a drive cylinder 131, which is a hydraulic cylinder. An oil pipe connects the drive cylinder 131 to the drive chamber 15, and the drive chamber 15 and drive cylinder 131 are connected by the oil pipe. The internal cavity of the drive cylinder 131 is a cylindrical space. From the cylinder opening to the bottom of the cylinder, the drive cylinder 131 is sequentially equipped with an oil reservoir connected to the drive cylinder 131, a second piston 1311 slidably connected to the inner cavity of the drive cylinder 131, a connecting block fixedly connected to the second piston 1311, and a motor 132 installed at the bottom of the drive cylinder 131. A lead screw 1321 is coaxially provided at the output end of the motor 132, and the lead screw 1321 is threadedly connected to the connecting block. The drive cylinder 131 is installed horizontally, and a vertical opening at the top of the drive cylinder 131 is provided for connecting... The oil can is connected to the inside of the drive cylinder 131 through the oil flow port. The second piston 1311 is connected to the opening of the drive cylinder 131 by a fourth elastic element 1312, which is a spring. When the motor 132 rotates, it drives the lead screw 1321 to rotate coaxially. Since the lead screw 1321 is threadedly connected to the connecting block, the connecting block also tends to rotate when the lead screw 1321 rotates. However, since the second piston 1311 and the inner wall of the drive cylinder 131 are provided with an axial sliding groove and a slider to achieve axial sliding connection, the rotation of the lead screw 1321 will not drive the second piston 1311 to rotate. The second piston 1311 can be smoothly driven to slide horizontally in the drive cylinder 131 by the rotation of the motor 132.

[0036] like Figures 2-5 As shown, when the second piston 1311 slides horizontally towards the opening of the drive cylinder 131 under the drive of the motor 132, the second piston 1311 squeezes the hydraulic oil in the drive cylinder 131 and enters the drive chamber 15 through the oil pipe. The oil drives the first piston 151 to push against the drive ring 142, thereby driving the release bearing 141 to slide towards the housing 31, so that the release bearing 141 pushes against the primary moving cone disk 41. When it is necessary for the release bearing 141 to slide away from the housing 31, the motor 132 drives the second piston 1311 to slide towards the motor 132. When the second piston 1311 slides in the opposite direction, the hydraulic oil in the drive chamber 15 is drawn back to the drive cylinder 131 under pressure. At this time, the third elastic element 111 pulls the drive ring 142 to slide in the opposite direction, thereby causing the release bearing 141 and the primary moving cone disk 41 to disengage.

[0037] The secondary moving cone disc 51 is located inside the housing 31 on the side close to the vehicle body. A first elastic element 511 is connected between the secondary moving cone disc 51 and the housing 31. The first elastic element 511 is a spring. The clutch includes a circular brake disc 53 fixedly mounted on the transmission. The brake disc 53 and the driven shaft 312 are coaxially arranged. The clutch also includes a number of brake shoes 54 centrally symmetrically arranged on the outer ring of the driven shaft 312. A second elastic element is connected between the brake shoes 54 and the driven shaft 312. The second elastic element is a tension spring.

[0038] When the actuator 1 uses hydraulic oil from the drive cylinder 131 to push the release bearing 141 against the primary moving cone disc 41, the primary moving cone disc 41 slides towards the primary fixed cone disc 42. Simultaneously, the primary moving cone disc 41 and the primary fixed cone disc 42 rotate coaxially. As the primary moving cone disc 41 moves, the distance between the drive wheels 4 decreases. At this time, the transmission belt, compressed by the inclined surface of the cone discs, increases the circumference of the transmission belt around the drive wheel 4, while the total length of the transmission belt remains unchanged. Therefore, at one end of the driven wheel 5, the tension of the transmission belt on the driven shaft 312 increases, and it compresses the cone discs on both sides of the driven wheel 5. Throughout the process, the first elastic element 511 continuously compresses the secondary moving cone disc 51 towards the secondary fixed cone disc 52, ensuring that the circumference of the transmission belt at the driven wheel 5 remains constant. When the elastic force of the first elastic element 511 is less than the squeezing force of the transmission belt, the radius of the transmission belt at the driven pulley 5 changes, resulting in a change in the transmission ratio and achieving speed change. When the crankshaft speed is very low, the crankshaft 311 and driven shaft 312 will naturally have low speeds. At this time, several brake shoes 54 move closer to the driven shaft 312 under the tension of the second spring. Therefore, the brake shoes 54 will not contact the brake disc 53. The brake disc 53 is coaxially set with the vehicle body rollers, so the rollers will not rotate. When the speeds of the crankshaft 311 and driven shaft 312 are high, the centrifugal force of several brake shoes 54 is greater than the tension of the second elastic element. At this time, the centrifugal force breaks free from the tension of the second elastic element, causing several brake shoes 54 to abut against the brake disc 53, thus achieving transmission connection.

[0039] like Figure 3 , Figure 5 As shown, the system also includes a sensing system 2 mounted on the mounting bracket 11. The sensing system 2 includes a displacement slider 23 fixedly connected to the drive ring 142. Since the drive ring 142 and the release bearing 141 are coaxially connected, the movement of the release bearing 141 can be directly measured by detecting the movement of the drive ring 142. A resistor 21 is also fixedly mounted on the mounting bracket 11. The resistor 21 is rod-shaped and coaxially arranged with the guide cylinder 14. The resistor 21 is parallel to the guide cylinder 14. A processor is also mounted on the mounting bracket 11. The processor is connected to the resistor 21, and a closed loop is formed between the processor and the resistor 21. The displacement slider is made of a conductive material. When the drive ring 142 drives the displacement sliding block to slide on the resistor 21, the processor detects the change in voltage in the closed loop and makes a judgment based on the program written in the processor. The judgment program associates the movement of the primary moving cone disk 41 with the corresponding transmission ratio of the transmission belt. In this judgment program, relevant experiments need to be performed in advance. The experiment is to push the primary moving cone disk 41 and detect the rotation speed of the drive wheel 4 and the driven wheel 5 respectively to calculate the transmission ratio. The transmission ratio, the movement of the primary moving cone disk 41 and the rotation speed are listed separately, and a structure tree is established based on the experimental data. The judgment program detects the speed change based on the structure tree.
