Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, and more particularly to a clutch actuator and an engine arrangement for a motorcycle. Background Art

[0002] Motorcycles are two-wheeled or three-wheeled vehicles driven by gasoline engines and steered by handlebars. They are light, flexible, and fast, and are widely used for patrols, passenger and cargo transportation, etc. As the power source of motorcycles, motorcycle engines ignite the fuel mixture entering the cylinder and convert the heat energy generated by its combustion into mechanical energy, and the crankshaft transmits the power to the rear wheel of the motorcycle through the transmission mechanism to convert it into the driving power of the vehicle.

[0003] Motorcycle actuators are usually used for shifting gears or controlling the release of the clutch. Actuators in the prior art usually adopt a power configuration form of electronically controlled hydraulic media. Using hydraulic oil circuits as actuators not only makes the structure complex, but also leads to high manufacturing and subsequent maintenance costs due to the large number of sensor elements. In addition, since the flow properties of hydraulic oil are affected by temperature, the actuator's execution speed remains unchanged at different temperatures, which in turn affects the handling performance. Summary of the invention

[0004] The present invention overcomes the shortcomings of the prior art clutch hydraulic actuator having a complex structure and poor maneuverability, and provides a motorcycle clutch actuator which has a simple structure and can reduce the weight of the overall control structure. The control is not affected by temperature and has excellent maneuverability.

[0006] In the present application, the worm gear transmission device is driven to move by the output end of the power output device, and the power is output from the output end of the worm gear transmission device, driving the first end rod to rotate, and then the first end rod drives the transmission rod to move, and then the transmission rod drives the second end rod to move, and the end of the second end rod away from the transmission rod is connected to the clutch lever, so that the second end rod can control the clutch lever to rotate, thereby controlling the separation and engagement of the clutch. The worm gear structure is used as the transmission component of the actuator, and the worm gear structure has the characteristic of one-way power transmission, so that the control performance is more stable. At the same time, the structure is simple, the weight of the overall control structure can be reduced, and the control is not affected by temperature, and it has the characteristics of excellent control performance.

[0009] Preferably, the transmission worm wheel is a fan-shaped structure, and the worm wheel cavity is a fan-shaped cavity adapted to the transmission worm wheel.

[0010] The transmission worm wheel is arranged in a fan-shaped structure, which can reduce the overall mass of the transmission worm wheel, save the installation space of the transmission worm wheel, and make the overall structure more compact compared with the traditional structure.

[0011] Preferably, an input structure installation cavity is provided between the worm cavity and the power installation cavity; an input transmission assembly is provided between the transmission worm and the power output device, and the input transmission assembly includes an input transmission member; an input transmission hole is provided on the input transmission member, an inner gear is provided on the inner side wall of the input rotating hole, an output gear is provided at the output end of the power output device and is eccentrically arranged with the inner gear; a transmission groove is provided at the bottom of the input transmission hole, and the transmission worm is inserted into the transmission groove.

[0012] In the present application, the output gear and the inner gear are eccentrically arranged, and the diameter of the output gear is smaller than the diameter of the inner gear, so that the power of the power output device can be directly transmitted to the input transmission member. At the same time, the inner gear and the output gear cooperate to form a simple reducer structure, which can convert the high speed and low torque of the power output device into a low speed and high torque output, thereby eliminating the need for the installation of the reducer, making the overall weight of the actuator lighter, and also making the overall structure more compact.

The output gear and the inner gear are eccentrically arranged, and the diameter of the output gear is smaller than the diameter of the inner gear, so that the power of the power output device can be directly transmitted to the input transmission member. At the same time, the inner gear and the output gear cooperate to form a simple reducer structure, which can convert the high speed and low torque of the power output device into a low speed and high torque output, thereby eliminating the need for the installation of the reducer, making the overall weight of the actuator lighter, and also making the overall structure more compact. The transmission worm wheel is arranged as a fan-shaped structure, which can reduce the overall mass of the transmission worm wheel compared to the traditional structure, save the installation space of the transmission worm wheel, and make the overall structure more compact.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figures 1 to 8 As shown, a motorcycle clutch actuator includes: a power output device 1, a worm gear transmission device 2 and a connecting rod transmission mechanism 3.

[0036] The connecting rod transmission mechanism 3 includes a transmission rod 33, a first end rod 31 and a second end rod 32. The first end rod 31 and the second end rod 32 are rotatably arranged at two ends of the transmission rod 33.

[0037] The input end of the worm gear transmission device 2 is connected to the output end of the power output device 1 ; the output end of the worm gear transmission device 2 is fixedly connected to the first end rod 31 .

[0038] The output end of the power output device 1 drives the worm gear transmission device 2 to move, and the power is output from the output end of the worm gear transmission device 2, driving the first end rod 31 to rotate, and then the first end rod 31 drives the transmission rod 33 to move, and then the transmission rod 33 drives the second end rod 32 to move, and the end of the second end rod 32 away from the transmission rod 33 is connected to the clutch lever 91, so that the second end rod 32 can control the clutch lever 91 to rotate, thereby controlling the separation and engagement of the clutch 9. The worm gear structure is used as the transmission component of the power actuator, and the worm gear structure has the characteristics of unidirectional power transmission, so that the control performance is more stable.

[0039] Specifically, the power output device 1 adopts a motor, and the power output device 1 includes but is not limited to the motor, and the output end of the motor is connected to the input end of the worm gear transmission device 2 .

[0040] In one embodiment, the worm gear transmission device 2 includes a housing 21, a transmission worm wheel 23 and a transmission worm 22, and the transmission worm wheel 23 and the transmission worm 22 are both arranged in the housing 21. The housing 21 is provided with a worm cavity 211 and a worm wheel cavity 212 which are interconnected, the transmission worm wheel 23 is arranged in the worm wheel cavity 212, and the transmission worm is arranged in the worm cavity 211; a power installation cavity 213 is arranged at one end of the worm cavity 211, the power installation cavity 213 is connected to the worm cavity 211, and the power output device 1 is fixedly arranged in the power installation cavity 213.

[0041] In the conventional structure, the motor needs to cooperate with the reducer to convert the high speed and low torque of the motor into low speed and high torque for external output. Since the reducer requires a certain installation space, in order to reduce the overall volume of the actuator in this application without affecting the normal power output of the power output device 1, an input transmission assembly 4 is arranged between the power output device 1 and the worm gear transmission device 2.

[0042] Specifically, an input structure installation cavity 214 is provided between the worm cavity 211 and the power installation cavity 213. An input transmission assembly 4 is provided between the transmission worm and the power output device 1, and the input transmission assembly 4 is installed in the structure installation cavity.

[0043] The input transmission assembly 4 in the present application includes an input transmission member 41; an input transmission hole 411 is provided on the input transmission member 41, an inner gear 412 is provided on the inner wall of the input rotating hole, an output gear 11 is provided at the output end of the power output device 1 with the inner gear 412 (i.e., an output gear 11 is provided at the output end of the motor), the output gear 11 is eccentrically arranged with the inner gear 412, and the diameter of the output gear 11 is smaller than the diameter of the inner gear 412. A transmission groove 413 is provided at the bottom of the input transmission hole 411, and a transmission head 221 matching the transmission groove 413 is provided at one end of the transmission worm; the transmission groove 413 in the present application is rectangular, the cross section of the transmission head 221 is the same as the shape of the transmission groove 413, and the transmission head at the end of the transmission worm 22 is inserted into the transmission groove 413.

[0044] The input transmission assembly 4 also includes an input bearing 42, which is disposed in the input structure mounting cavity 214, and the input gear sleeve is disposed on the periphery of the input transmission member 41. The input bearing 42 cooperates with the input transmission member 41, so that the input transmission member 41 can rotate more freely, and the power of the power output device 1 can be more stably transmitted to the transmission worm through the input transmission member 41.

[0045] In the present application, the output gear 11 and the inner gear 412 are eccentrically arranged, and the diameter of the output gear 11 is smaller than the diameter of the inner gear 412, so that the power of the power output device 1 can be directly transmitted to the input transmission member 41. At the same time, the inner gear 412 cooperates with the output gear 11 to form a simple reducer structure, which can convert the high speed and low torque of the power output device 1 into a low speed and high torque output, thereby eliminating the need for the installation of the reducer, making the overall weight of the actuator lighter, and also making the overall structure more compact.

[0046] In order to make the overall structure more compact and lighter, the transmission worm wheel 23 is set to a fan-shaped structure, and the worm wheel cavity 212 is set to a fan-shaped cavity adapted to the transmission worm wheel 23; a worm wheel cover 215 is set on one side of the worm wheel cavity 212, and the worm wheel cover 215 is removed to facilitate the installation of the transmission worm wheel 23. Compared with the traditional structure, the overall mass of the transmission worm wheel 23 can be reduced, the installation space of the transmission worm wheel 23 can be saved, and the overall structure can be more compact.

[0047] A limited abutment 5 is provided at the end of the input structure installation cavity 214. The limited abutment 5 includes a first plate 51 and a second plate 52. The first plate 51 and the second plate 52 are eccentrically arranged. The first plate 51 cooperates with the power installation cavity 213, and the second plate 52 cooperates with the input structure installation cavity 214. A central through hole 53 is provided through the limited abutment 5. The central through hole 53 penetrates the first plate 51 and the second plate 52. A boss 12 is provided at the end of the power output device 1. The boss 12 is matched with the central through hole 53 during assembly. The first plate 51 and the second plate 52 cooperate with the inner side walls of the power installation cavity 213 and the input structure installation cavity 214, respectively, and play a relative role on the power output device 1. Since the output gear 11 and the inner gear 412 are eccentrically meshed, when the output gear 11 is rotating, the power output device 1 is subjected to a large eccentric force, so that the power output device 1 is always in an unbalanced state, and the noise generated is relatively large. Therefore, by providing the limiting abutment member 5 , a buffering effect of limiting the power output device 1 can be achieved, thereby reducing the vibration generated when the power output device 1 is running.

[0048] In addition, a second rubber ring 7 is sleeved on the outer periphery of the second plate 52, and a first rubber ring 6 is arranged on the outer periphery of the boss 12. When the actuator is assembled, a ring groove is arranged inside the input structure installation cavity 214, and the second rubber ring 7 will abut against the ring groove; and the second rubber ring 7 will abut against the end of the power installation cavity 213. The first rubber ring 6 and the second rubber ring 7 both play a role in buffering and shock absorption, so that the vibration generated by the power output device 1 during operation can be smaller.

[0049] A worm output shaft 24 is arranged at the axis of the transmission worm wheel 23, and a spline groove 241 is arranged at the periphery of one end of the worm output shaft 24; a spline hole 311 matching the spline groove 241 is arranged on the first end rod 31; a spline opening 312 is arranged on the side wall of the spline hole 311, and both sides of the spline opening 312 are fastened and connected by threads. The power of the transmission worm wheel 23 is transmitted by the spline groove 241 and the spline hole 311, which is not only convenient for installation, but also can drive the first end rod 31 to rotate through the worm output shaft 24 when the transmission worm wheel 23 rotates.

[0050] The working principle of the present application is as follows: the output gear 11 of the power output device 1 rotates, and the output gear 11 meshes with the inner gear 412, thereby driving the output transmission member to rotate, and then driving the transmission worm to rotate, and the transmission worm meshes with the transmission worm wheel 23, driving the transmission worm wheel 23 to rotate, and then the transmission turbine drives the worm wheel output shaft 24 to rotate, thereby driving the first end rod 31 to rotate, the first end rod 31 drives the transmission rod 33 to move, the transmission rod 33 drives the second end rod 32 to rotate around the clutch lever 91, and the second end cover drives the clutch lever 91 to rotate, thereby realizing the control of the separation and engagement of the clutch 9.

[0051] In the present application, a worm gear structure is used as the transmission component of the actuator. By utilizing the characteristic of unidirectional power transmission of the worm gear structure, the handling performance can be more stable. The output gear 11 and the inner gear 412 are eccentrically arranged, and the diameter of the output gear 11 is smaller than the diameter of the inner gear 412, so that the power of the power output device 1 can be directly transmitted to the input transmission member 41. At the same time, the inner gear 412 and the output gear 11 cooperate to form a simple reducer structure, which can convert the high speed and low torque of the power output device 1 into a low speed and high torque output, thereby eliminating the need for the installation of the reducer, making the overall weight of the actuator lighter, and also making the overall structure more compact. The transmission worm wheel 23 is arranged in a fan-shaped structure, which can reduce the overall mass of the transmission worm wheel 23 compared with the traditional structure, save the installation space of the transmission worm wheel 23, and make the overall structure more compact.

[0052] Example 2: Reference Figures 1 to 8 As shown, an engine arrangement includes: a motorcycle clutch actuator, which also includes an engine 8 and a clutch 9 connected to the output end of the engine 8; a clutch lever 91 is arranged in the clutch 9. The end of the second end rod 32 away from the transmission rod 33 is connected to the clutch lever 91. When the second end rod 32 rotates, it can drive the clutch lever 91 to rotate.

[0053] Several support rods 81 are arranged outside the engine 8, and four support rods 81 are arranged in the present application. Support holes are arranged at the ends of the support rods 81; mounting holes 25 cooperating with the support holes are arranged outside the worm gear transmission device 2; the screw passes through the mounting holes 25 and is threadedly connected with the support holes. The coordination between the mounting holes and the support holes facilitates the installation of the clutch actuator of the motorcycle.

[0054] A motorcycle clutch actuator comprises: a power output device 1, a worm gear transmission device 2 and a connecting rod transmission mechanism 3.

[0055] The connecting rod transmission mechanism 3 includes a transmission rod 33, a first end rod 31 and a second end rod 32. The first end rod 31 and the second end rod 32 are rotatably arranged at two ends of the transmission rod 33.

[0056] The input end of the worm gear transmission device 2 is connected to the output end of the power output device 1 ; the output end of the worm gear transmission device 2 is fixedly connected to the first end rod 31 .

[0057] The output end of the power output device 1 drives the worm gear transmission device 2 to move, and the power is output from the output end of the worm gear transmission device 2, driving the first end rod 31 to rotate, and then the first end rod 31 drives the transmission rod 33 to move, and then the transmission rod 33 drives the second end rod 32 to move, and the end of the second end rod 32 away from the transmission rod 33 is connected to the clutch lever 91, so that the second end rod 32 can control the clutch lever 91 to rotate, thereby controlling the separation and engagement of the clutch 9. The worm gear structure is used as the transmission component of the power actuator, and the worm gear structure has the characteristics of unidirectional power transmission, so that the control performance is more stable.

[0058] Specifically, the power output device 1 adopts a motor, and the power output device 1 includes but is not limited to the motor, and the output end of the motor is connected to the input end of the worm gear transmission device 2 .

[0060] In the conventional structure, the motor needs to cooperate with the reducer to convert the high speed and low torque of the motor into low speed and high torque for external output. Since the reducer requires a certain installation space, in order to reduce the overall volume of the actuator in this application without affecting the normal power output of the power output device 1, an input transmission assembly 4 is arranged between the power output device 1 and the worm gear transmission device 2.

A transmission groove 413 is provided at the bottom of the input transmission hole 411, and a transmission head 221 matching the transmission groove 413 is provided at one end of the transmission worm; the transmission groove 413 in the present application is rectangular, the cross section of the transmission head 221 is the same as the shape of the transmission groove 413, and the transmission head at the end of the transmission worm 22 is inserted into the transmission groove 413.

[0063] The input transmission assembly 4 also includes an input bearing 42, which is disposed in the input structure mounting cavity 214, and the input gear sleeve is disposed on the periphery of the input transmission member 41. The input bearing 42 cooperates with the input transmission member 41, so that the input transmission member 41 can rotate more freely, and the power of the power output device 1 can be more stably transmitted to the transmission worm through the input transmission member 41.

[0064] In the present application, the output gear 11 and the inner gear 412 are eccentrically arranged, and the diameter of the output gear 11 is smaller than the diameter of the inner gear 412, so that the power of the power output device 1 can be directly transmitted to the input transmission member 41. At the same time, the inner gear 412 cooperates with the output gear 11 to form a simple reducer structure, which can convert the high speed and low torque of the power output device 1 into a low speed and high torque output, thereby eliminating the need for the installation of the reducer, making the overall weight of the actuator lighter, and also making the overall structure more compact.

[0065] In order to make the overall structure more compact and lighter, the transmission worm wheel 23 is set to a fan-shaped structure, and the worm wheel cavity 212 is set to a fan-shaped cavity adapted to the transmission worm wheel 23; a worm wheel cover 215 is set on one side of the worm wheel cavity 212, and the worm wheel cover 215 is removed to facilitate the installation of the transmission worm wheel 23.

A boss 12 is provided at the end of the power output device 1. The boss 12 is matched with the central through hole 53 during assembly. The first plate 51 and the second plate 52 cooperate with the inner side walls of the power installation cavity 213 and the input structure installation cavity 214, respectively, and play a relative role on the power output device 1. Since the output gear 11 and the inner gear 412 are eccentrically meshed, when the output gear 11 is rotating, the power output device 1 is subjected to a large eccentric force, so that the power output device 1 is always in an unbalanced state, and the noise generated is relatively large. Therefore, by providing the limiting abutment member 5 , a buffering effect of limiting the power output device 1 can be achieved, thereby reducing the vibration generated when the power output device 1 is running.

The power of the transmission worm wheel 23 is transmitted by the spline groove 241 and the spline hole 311, which is not only convenient for installation, but also can drive the first end rod 31 to rotate through the worm output shaft 24 when the transmission worm wheel 23 rotates.

[0069] The working principle of the present application is as follows: the output gear 11 of the power output device 1 rotates, and the output gear 11 meshes with the inner gear 412, thereby driving the output transmission member to rotate, and then driving the transmission worm to rotate, and the transmission worm meshes with the transmission worm wheel 23, driving the transmission worm wheel 23 to rotate, and then the transmission turbine drives the worm wheel output shaft 24 to rotate, thereby driving the first end rod 31 to rotate, the first end rod 31 drives the transmission rod 33 to move, the transmission rod 33 drives the second end rod 32 to rotate around the clutch lever 91, and the second end cover drives the clutch lever 91 to rotate, thereby realizing the control of the separation and engagement of the clutch 9.

[0070] In the present application, a worm gear structure is used as the transmission component of the actuator. By utilizing the characteristic of unidirectional power transmission of the worm gear structure, the handling performance can be more stable. The output gear 11 and the inner gear 412 are eccentrically arranged, and the diameter of the output gear 11 is smaller than the diameter of the inner gear 412, so that the power of the power output device 1 can be directly transmitted to the input transmission member 41. At the same time, the inner gear 412 and the output gear 11 cooperate to form a simple reducer structure, which can convert the high speed and low torque of the power output device 1 into a low speed and high torque output, thereby eliminating the need for the installation of the reducer, making the overall weight of the actuator lighter, and also making the overall structure more compact. The transmission worm wheel 23 is arranged in a fan-shaped structure, which can reduce the overall mass of the transmission worm wheel 23 compared with the traditional structure, save the installation space of the transmission worm wheel 23, and make the overall structure more compact.
