Description

Technical Field

[0001] The present invention relates to the field of ECVT, and particularly to a motorcycle ECVT actuator. Background Art

[0002] The ECVT actuator of a motorcycle is an electronic continuously variable transmission technology. Its core lies in achieving continuous changes in the transmission ratio through an electronic control system, thereby optimizing the vehicle's power output and fuel economy. An automatic transmission system that can continuously change the transmission ratio is characterized by the fact that it does not require fixed gears. It realizes a smooth acceleration and deceleration process by adjusting the contact radius of the drive belt or chain. This type of transmission is widely used in vehicles such as cars and motorcycles, and has the advantages of simple structure, small volume, good fuel economy, and high driving comfort.

[0003] The existing continuously variable transmission mechanism of a scooter mainly adjusts the continuously variable transmission through the method of a pulley disc and pulley beads. The continuously variable transmission mechanism includes a gearbox installed on the vehicle body. A crankshaft is provided at the output of the gearbox. A housing is installed on the cylinder block of the gearbox. A driven shaft is rotatably provided inside the housing. A driving wheel and a driven wheel are respectively provided on the crankshaft and the driven shaft, and the two are connected by a drive belt. The driving wheel includes a primary movable cone disc and a primary fixed cone disc, and the primary movable cone disc is set as the pulley disc. The driven wheel includes a secondary movable cone disc and a secondary fixed cone disc.

[0004] However, in the existing pulley disc structure, it mainly relies on the centrifugal force during rotation to squeeze the inner cone disc of the driving wheel through the pulley beads to adjust the gap between the two cone discs on both sides of the driving wheel. The inclined housing and the pulley beads squeeze the sliding cone disc to achieve the movement of the cone disc. The speed change process mainly relies on the frictional transmission of the pulley beads, resulting in low transmission efficiency and high fuel consumption. Summary of the Invention

[0005] The present invention aims to provide a motorcycle ECVT actuator to solve the problems of low transmission efficiency and high fuel consumption in continuously variable transmission.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A motorcycle ECVT actuator includes a coaxial sliding structure and a driving structure connected to the coaxial sliding structure. The coaxial sliding structure is used to push the primary movable cone disc to slide on the crankshaft. The driving structure is used to drive the coaxial sliding structure to slide. The driving structure includes a driving chamber and a driving cylinder communicated with the driving chamber. The driving chamber is coaxially arranged with the crankshaft. A first piston is arranged inside the driving chamber. A fluid is arranged between the driving cylinder and the driving chamber. The driving cylinder drives the first piston to slide through the fluid, so that the first piston drives the primary movable cone disc to slide on the crankshaft through the coaxial sliding structure.

[0007] The beneficial effects of this solution are as follows: By setting up an actuator, the actuator is separately installed in the gearbox, and the driving method and mechanism of the primary moving conical disk are completely separated from the crankshaft. In the prior art, the rotation of the crankshaft drives the pulley disk, i.e., the primary moving conical disk, to rotate, and the speed is adjusted by changing the rotational speed of the output crankshaft of the gearbox. The gearbox drives the crankshaft to rotate and generates centrifugal force on the pulley beads in the pulley disk, and the pulley disk is pushed through friction, resulting in the pulley disk sliding on the crankshaft. In this solution, the housing is installed on the cylinder block of the gearbox, and a coaxial sliding structure is coaxially arranged with the crankshaft on the cylinder block, and the sliding of the coaxial sliding structure is adjusted by a driving structure fixedly installed with the housing separately, so that the coaxial sliding structure abuts against the primary moving conical disk. Therefore, the continuously variable transmission driving form in the prior art is changed. Instead of relying on friction transmission, the primary moving conical disk is driven to slide without affecting coaxial rotation, thereby changing the distance between the driving wheels.

[0008] In the prior art, the friction transmission and speed change of the pulley disk result in a reduction in the transmission efficiency of the crankshaft. After the transmission efficiency of the crankshaft is reduced, it directly leads to an increase in fuel consumption. In addition, the pulley disk is extremely prone to wear under long-term friction work, so it needs to be replaced regularly. However, due to the complex structure inside the gearbox and the fact that the pulley disk is installed on the inner side of the crankshaft close to the vehicle body, the disassembly and installation are relatively cumbersome, increasing the consumption cost of users. In this solution, the coaxial sliding structure will push it on the premise of coaxial rotation with the crankshaft and the primary moving conical disk. The coaxial sliding structure and the primary moving conical disk are relatively stationary, so the structure is stable and not easily damaged. Therefore, this solution can improve the transmission efficiency in continuously variable transmission and reduce fuel consumption.

[0009] In addition, the driving cavity uses a fluid to drive the release bearing to abut against the primary moving conical disk. Since the fluid is incompressible, smooth speed changes and precise control can be achieved. Compared with the prior art, it can be applied to large-displacement vehicle models.

[0010] Preferably, as an improvement, the coaxial sliding structure includes a guide cylinder coaxially arranged with the crankshaft and sleeved outside the crankshaft, and also includes a release bearing axially slidably connected to the guide cylinder. The driving structure is connected to the release bearing and is used to drive the release bearing to abut against the primary moving conical disk.

[0011] The beneficial effects of this solution are as follows: The guide cylinder and the crankshaft are coaxially arranged, the release bearing is slidably connected to the guide cylinder, and the driving structure abuts the release bearing against the primary moving conical disk. The release bearing can not only satisfy the sliding along the guide cylinder but also satisfy the coaxial rotation with the crankshaft. Therefore, when the driving structure abuts the release bearing against the primary moving conical disk, the release bearing can rotate coaxially and at the same speed as the crankshaft and the primary moving conical disk, that is, the release bearing and the crankshaft and the primary moving conical disk are relatively stationary, and it can also ensure the relative sliding between the release bearing and the guide cylinder, and the function of the coaxial sliding structure can be realized.

[0012] Preferably, as an improvement, a driving member is installed on the driving cylinder, and the driving member drives the first piston to slide and abut against the primary moving cone disk through a fluid.

[0013] Preferably, as an improvement, the fluid is set as hydraulic oil, the driving member is set as a motor, a second piston is slidably connected in the driving cylinder, a lead screw is coaxially arranged at the output end of the motor, and the lead screw is threadedly connected with the second piston.

[0014] The beneficial effect of this solution is that the motor drives the second piston to slide in the driving cylinder through the lead screw, which can improve the flexibility of the structure.

[0015] Preferably, as an improvement, a first elastic member is arranged between the cylinder block and the release bearing, the first elastic member is set as a tension spring, and the tension spring is used to drive the release bearing to reset on the guide cylinder.

[0016] The beneficial effect of this solution is that the first piston abuts against the release bearing, and finally the release bearing abuts against the primary moving cone disk. Therefore, the driving structure is mainly used to push out the first piston. When resetting, the tension spring drives the release bearing to reset, which can ensure the stability of the structure.

[0017] Preferably, as an improvement, a second elastic member is arranged between the second piston and the driving cylinder.

[0018] Preferably, as an improvement, the housing is provided with a sensing system. The sensing system includes a resistance member and a sensor fixed to the housing. The resistance member is arranged coaxially with the guide cylinder, and the release bearing is arranged to slide relative to the resistance member. The housing is also installed with a processor, and the processor is used to convert the movement signal of the release bearing into an electrical signal.

[0019] The beneficial effect of this solution is that by setting the sensing system, since the release bearing is arranged to slide relative to the resistance member, when the release bearing slides along the axial direction of the guide cylinder under the drive of the driving structure, in the closed loop formed among the processor, the resistance member and the release bearing, due to the change of the resistance on the resistance member, finally the current and voltage in the closed loop change. Therefore, the processor can detect the change, achieving the purpose of converting the movement signal of the release bearing into an electrical signal.

[0020] Preferably, as an improvement, a mounting frame is fixed outside the housing, and the coaxial sliding structure and the driving structure are externally hung on the housing through the mounting frame.

[0021] The beneficial effects of this solution are as follows: Since the coaxial sliding mechanism in the prior art is separately installed on the gearbox cylinder block and the driving mechanism is installed on the housing, which is arranged inside the vehicle body through the housing, and its structure has no strong correlation with the structure inside the gearbox, it is possible to achieve the purpose of externally mounting it on the gearbox; however, in the prior art, since the driving wheel needs to be driven by the gearbox, the conventional setting is to place the primary driving cone disk on the side close to the vehicle body and the secondary driving cone disk on the side far from the vehicle body. But when the actuator in this solution needs to be externally mounted on the gearbox, only the primary driving cone disk and the primary fixed cone disk, and the secondary driving cone disk and the secondary fixed cone disk in the prior art need to be installed in reverse, so that the primary driving cone disk is located on the side far from the vehicle body inside the gearbox and the secondary driving cone disk is located on the side close to the vehicle body inside the gearbox, thus realizing the external mounting of the actuator. When the product is damaged or aged and needs to be replaced or repaired, it is not necessary to disassemble the entire continuously variable transmission mechanism, reducing the manual workload and also reducing the maintenance cost for consumers.

[0022] In addition, since the continuously variable transmission structure in the prior art has been mass-produced and sold, a large number of products already exist in civilian use. Due to the influence of variables such as quality, usage environment, and usage frequency, the variable speed structures of thousands of users are frequently damaged or aged. However, in the past, in such cases, users could only request replacement or repair at a high price. During this period, depending on the degree of damage and aging, the parts to be replaced are also different. Users have to pay both for the parts and the labor cost. Neither consumers nor repairers can guarantee when the next failure will occur; but for the actuator in this solution, for customers and users, they have more options. They can directly disassemble the variable speed structure and reverse-install the driving wheel, and directly externally mount the ECVT actuator of this solution on the gearbox. For merchants, they can not only ensure the complete sale of the ECVT actuator product but also ensure the quality problem, ultimately leading to the good reputation of merchants and manufacturers standing firm. Therefore, it is beneficial for both the market and has a positive promoting effect on the market.

[0023] Preferably, as an improvement, the guide cylinder is fixedly arranged on the cylinder block, and the guide cylinder does not contact the crankshaft.

[0024] The beneficial effect of this solution is that the guide cylinder does not contact the crankshaft, that is, the inner diameter of the guide cylinder is larger than the diameter of the crankshaft, which can ensure the normal operation of the coaxial sliding structure.

[0025] Preferably, as an improvement, the drive chamber is arranged in an annular shape and is coaxially arranged with the guide cylinder. The drive chamber is arranged near the end opening of the release bearing. The drive chamber is sealed by a first piston. The guide cylinder wall is located between the release bearing and the drive chamber and is slidably provided with a drive ring. The drive ring is coaxially arranged with the guide cylinder, and the radial thickness of the drive ring along the guide cylinder is not greater than the radial thickness of the drive chamber along the guide cylinder.

[0026] The beneficial effects of this solution are as follows: the driving mechanism drives the release bearing to slide on the guide cylinder through the first piston and the driving ring. In addition, by setting the thickness of the driving ring and the driving cavity, when the release bearing is reset, the driving ring can be embedded in the driving cavity. Since there is residual hydraulic oil on the inner wall of the driving cavity, the driving ring can be soaked with hydraulic oil. The reciprocating sliding causes the driving ring to bring the hydraulic oil into the sliding connection between the driving ring and the guide cylinder, and the sliding connection between the release bearing and the guide cylinder, respectively, so that most of the mechanism is in contact with the hydraulic oil, thereby improving the lubrication performance and increasing the service life of the parts.

DETAILED DESCRIPTION

[0028] The following is further described in detail through specific implementation methods: The reference numerals in the drawings of the specification include: actuator 1, mounting frame 11, tension spring 111, coaxial sliding structure 12, driving structure 13, driving cylinder 131, second piston 1311, second elastic member 1312, motor 132, screw rod 1321, guide cylinder 14, release bearing 141, driving ring 142, driving chamber 15, first piston 151, sensing system 2, resistor 21, sensor 22, displacement slider 23, ECVT transmission mechanism 3, housing 31, crankshaft 311, driven shaft 312, driving wheel 4, primary movable cone disc 41, primary fixed cone disc 42, driven wheel 5, secondary movable cone disc 51, secondary fixed cone disc 52.

[0029] Example 1 Embodiment 1 is basically as attached Figure 1-2As shown in the figure, the motorcycle ECVT actuator includes a housing 31 fixedly connected to the transmission. The housing 31 is fixedly connected to the transmission cylinder block by bolts. The actuator 1 further includes a coaxial sliding structure 12 disposed in the cylinder block. The coaxial sliding structure 12 includes a guide cylinder 14 fixedly provided in the cylinder block, and the inner circle cross-sectional diameter of the guide cylinder 14 is larger than the cross-sectional diameter of the crankshaft 311. The end of the crankshaft 311 in the transmission passes through the guide cylinder 14. Neither the guide cylinder 14 nor the housing 31 contacts the crankshaft 311. The coaxial sliding structure 12 further includes a separating bearing 141 slidably connected to the end of the guide cylinder 14 near the primary driving cone disc 41. The inner circle cross-sectional diameter of the separating bearing 141 is equal to the outer circle cross-sectional diameter of the guide cylinder 14. A chute and slider structure is provided between the outer circle of the guide cylinder 14 and the inner circle of the separating bearing 141 to achieve the sliding connection between the separating bearing 141 and the guide cylinder 14.

[0030] As Figure 1-2 shown in the figure, the actuator 1 further includes a driving structure 13 connected to the housing 31 and used to drive the separating bearing 141 to slide on the guide cylinder 14. The driving structure 13 includes a driving cavity 15 axially provided on the outer circle of the guide cylinder 14. The driving cavity 15 is set as an annular space coaxial with the guide cylinder 14. A first piston 151 is slidably connected between the driving cavity 15 and the outer wall of the guide cylinder 14. The first piston 151 is annular and is embedded in the annular space of the driving cavity 15. A sealed space is formed at the top of the driving cavity 15 through the first piston 151. A driving ring 142 is also slidably connected to the outer circle of the guide cylinder 14. The driving ring 142 is fixedly connected to the separating bearing 141. A tension spring 111 is connected between the driving ring 142 and the cylinder block. Under normal circumstances, the tension spring 111 pulls the separating bearing 141 away from the primary driving cone disc 41 through the driving ring 142. The inner circle cross-sectional diameter of the driving ring 142 is equal to the outer circle cross-sectional diameter of the guide cylinder 14. A chute and slider structure is also provided between the inner wall of the driving ring 142 and the outer wall of the guide cylinder 14 to achieve the sliding connection between the driving ring 142 and the guide cylinder 14. The radial thickness of the driving ring 142 along the guide cylinder 14 is not greater than the radial thickness of the driving cavity 15 along the guide cylinder 14.

[0031] The drive structure 13 further includes a drive cylinder 131. The drive cylinder 131 is set as a hydraulic cylinder. There is an oil pipe connected between the drive cylinder 131 and the drive chamber 15. The drive chamber 15 and the drive cylinder 131 are communicated through the oil pipe. The internal cavity of the drive cylinder 131 is set as a columnar space. From the opening of the cylinder body to the bottom of the cylinder, the drive cylinder 131 is successively provided with an oil pot 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 end of the drive cylinder 131. The output end of the motor 132 is coaxially provided with a lead screw 1321. The lead screw 1321 is threadedly connected to the connecting block. When the drive cylinder 131 is installed, it is placed horizontally. A fluid flow port for connecting the oil pot is vertically opened at the top end of the drive cylinder 131. The oil pot is communicated with the inside of the cylinder body of the drive cylinder 131 through the fluid flow port. A second elastic member 1312 is connected between the second piston 1311 and the opening of the drive cylinder 131. The second elastic member 1312 is set as 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, when the lead screw 1321 rotates, the connecting block also has a tendency to rotate. However, since an axial sliding connection is realized between the second piston 1311 and the inner wall of the drive cylinder 131 through an axial chute and a slider, the lead screw 1321 will not drive the second piston 1311 to rotate when it rotates. The second piston 1311 can be smoothly driven to slide horizontally in the drive cylinder 131 by the rotation of the motor 132.

[0032] 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 to enter the drive chamber 15 through the oil pipe. The oil drives the first piston 151 to press against the drive ring 142, thereby driving the release bearing 141 to slide towards the primary driving cone disc 41, so that the release bearing 141 presses against the primary driving cone disc 41. When the release bearing 141 needs to slide in the reverse direction, the motor 132 drives the second piston 1311 to slide towards the motor 132. When the second piston 1311 slides in the reverse direction, the hydraulic oil in the drive chamber 15 is drawn back into the drive cylinder 131 under the action of pressure. At this time, the tension spring 111 pulls the drive ring 142 to slide in the reverse direction, so that the release bearing 141 and the primary driving cone disc 41 are separated from contact.

[0033] As Figure 2As shown in the figure, it further includes a sensing system 2 disposed on the housing 31. The sensing system 2 includes a displacement slider 23 fixedly connected to the driving ring 142. Since the driving ring 142 and the release bearing 141 are coaxially connected, the movement amount of the release bearing 141 can be directly measured by detecting the movement amount of the driving ring 142. A resistance member 21 is fixedly provided on the housing 31. The resistance member 21 is provided in a rod shape and is coaxially arranged with the guide cylinder 14. The resistance member 21 is parallel to the guide cylinder 14. The housing 31 is also equipped with a processor, and the processor is connected to the resistance member 21. A closed loop is formed between the processor and the resistance member 21. The displacement slider is made of a conductive material. When the driving ring 142 drives the displacement slider to slide on the resistance member 21, the processor detects the change in voltage in the closed loop and makes a judgment according to the program written in the processor. In the written judgment program, the movement of the primary moving cone disk 41 and the transmission ratio of the corresponding transmission belt are associated. In this written judgment program, relevant experiments need to be done in advance. The experiment is to calculate the transmission ratio by pushing the primary moving cone disk 41 and detecting the rotational speeds of the driving wheel 4 and the driven wheel 5 respectively. The transmission ratio, the movement of the primary moving cone disk 41, and the rotational speed are listed as data respectively, and a structure tree is established based on the test data. The judgment program detects the speed change according to the structure tree.

[0034] Embodiment 2 Embodiment 2 is basically as shown in the appendix Figures 3-5 As shown in the figure, the difference between Embodiment 2 and Embodiment 1 is that: As Figures 3-5 As shown in the figure, a mounting bracket 11 is fixedly installed on the outside of the housing 31. The actuator 1 is externally hung and fixedly installed on the housing 31 through the mounting bracket 11. Specifically, the guide cylinder 14 is fixedly provided on the mounting bracket 11. At this time, it is necessary to reinstall the direction arrangement of the driving wheel 4 on the crankshaft 311 in the gearbox, and other structures remain unchanged. That is, a crankshaft 311 and a driven shaft 312 are respectively rotatably provided at both ends in the gearbox. A driving wheel 4 and a driven wheel 5 are coaxially provided on the crankshaft 311 and the driven shaft 312 respectively. A transmission belt is connected between the driving wheel 4 and the driven wheel 5. The driving wheel 4 includes a primary fixed cone disk 42 close to the inner side of the vehicle body and a primary moving cone disk 41 far from the vehicle body on the outside. The primary fixed cone disk 42 is coaxially fixed to the crankshaft 311, and the primary moving cone disk 41 is coaxially slidably connected to the crankshaft 311. The primary moving cone disk 41 is coaxially fixedly welded with a sleeve, and the inner diameter of the sleeve is equal to the cross-sectional diameter of the crankshaft 311. Axial sliding connection is realized between the crankshaft 311 and the inner circle of the sleeve through the cooperation of a chute and an axial slider, so as to realize the sliding connection between the primary moving cone disk 41 and the crankshaft 311.

[0035] The mounting bracket 11 of the actuator 1 is fixedly installed on the outside of the transmission by bolts. At this time, the guide cylinder 14 is opened on the side of the mounting bracket 11 close to the housing 31, the driving cavity 15 is arranged at one end of the guide cylinder 14 away from the housing 31, the secondary moving cone disk 51 is located on the side close to the vehicle body inside the housing 31, and a spring for pressing the secondary moving cone disk 51 against the secondary fixed cone disk 52 is connected between the secondary moving cone disk 51 and the housing 31. A clutch is also provided, which includes a circular brake disk fixedly arranged on the transmission. The brake disk and the driven shaft 312 are coaxially arranged. The clutch also includes a plurality of brake shoes symmetrically arranged around the outer circle of the driven shaft 312. An elastic member is connected between the brake shoes and the driven shaft 312 to mainly pull the brake shoes towards the center of the driven shaft 312.

[0036] When the actuator 1 uses the hydraulic oil of the driving cylinder 131 to make the release bearing 141 press against the primary moving cone disk 41, at this time, the primary moving cone disk 41 slides towards the primary fixed cone disk 42. At the same time, the primary moving cone disk 41 and the primary fixed cone disk 42 rotate coaxially together. As the primary moving cone disk 41 moves, the distance between the centers of the driving wheels 4 decreases. At this time, the transmission belt is extruded by the inclined surface of the cone disk, so that the circumferential radius of the transmission belt around the driving wheel 4 increases. At the same time, the total length of the transmission belt remains unchanged. Therefore, at one end of the driven wheel 5, the pulling force of the transmission belt on the driven shaft 312 becomes larger, and the cone disks on both sides of the driven wheel 5 are squeezed. During the whole process, the spring always presses the secondary moving cone disk 51 towards the secondary fixed cone disk 52, so that the circumferential radius of the transmission belt at the driven wheel 5 always remains the largest. When the spring force is less than the extrusion force of the transmission belt, the circumferential radius of the transmission belt at the driven wheel 5 changes, resulting in a change in the transmission ratio and realizing speed change. When the rotational speed of the crankshaft is very low, it will naturally lead to a low rotational speed of the crankshaft 311 and the driven shaft 312. At this time, a plurality of brake shoes approach the driven shaft 312 under the pulling force of the elastic member. Therefore, the brake shoes will not contact the brake disk at this time. The brake disk is coaxially arranged with the vehicle body roller, so the roller will not rotate. When the rotational speeds of the crankshaft 311 and the driven shaft 312 are relatively large, the centrifugal force of a plurality of brake shoes is greater than the pulling force of the second elastic member 1312. At this time, the centrifugal force breaks away from the pulling force of the second elastic member 1312, so that a plurality of brake shoes press against the brake disk to realize transmission connection.

[0037] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as known characteristics are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solutions of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners in the specification can be used to interpret the content of the claims.
