DETAILED DESCRIPTION

[0024] The embodiments of the present utility model are described in detail below.

[0025] Example 1:

[0026] like Figure 1-5 As shown, the present invention discloses a clutch control device, which includes a clutch actuator push rod 3 connected to the clutch for driving the clutch to disengage or engage. An automatic drive module, used to drive the clutch actuator push rod 3, includes a sensor unit, a control unit, and an actuator unit.

[0027] The sensor unit is used to monitor vehicle operating parameters related to clutch opening and closing control and send the vehicle operating parameters to the control unit. In a specific embodiment, vehicle speed, engine speed, and gear shift signal are closely related to clutch opening and closing control. Accordingly, the sensor unit includes at least: a vehicle speed sensor for real-time monitoring of vehicle speed; an engine speed sensor for real-time monitoring of engine speed; and a gear shift sensor, which is arranged on one side of the vehicle's gear lever and is used to detect the position of the gear lever. The control unit (ECU) can determine whether to perform a gear shift operation based on the gear lever position, and then determine whether the clutch is open or closed. It will be understood by those skilled in the art that if it is necessary to control the opening and closing of the clutch in combination with other vehicle operating parameters, corresponding sensors need to be provided to obtain the corresponding vehicle operating parameters. In a preferred embodiment, the sensor unit includes a position sensor for detecting the current position of the clutch actuator rod to determine the current clutch opening and closing state. Specifically, the position sensor can determine the current clutch opening and closing state by detecting the position of the clutch actuator rod or the transmission component that drives the clutch actuator rod.

[0028] The control unit processes the vehicle operating parameters and sends control instructions to the execution unit; in an embodiment, the control unit is an ECU, which processes the signal obtained by the transmitter unit and processes it to determine whether the clutch needs to be disengaged or engaged, and sends corresponding control instructions to the execution unit to drive the clutch push rod 3 to move.

[0029] The execution unit includes a drive motor 4 and a transmission assembly 5. The output shaft of the drive motor 4 is connected to the clutch execution push rod 3 through the transmission assembly 5. The drive motor 4 includes a first drive motor and a second drive motor. The output shafts of the first drive motor and the second drive motor are respectively connected to the transmission assembly 5. The first drive motor and the second drive motor can synchronously and independently drive the transmission assembly 5. A dual-motor drive is set up, and the first drive motor and the second drive motor are connected to the same set of transmission assembly 5. When both motors are working normally, they can synchronously drive the transmission assembly 5 and then control the clutch execution push rod 3 to move. Even if any drive motor 4 fails, the other drive motor 4 can still independently drive the transmission assembly 5 and then control the clutch execution push rod 3 to move.

[0030] The working process of the automatic drive module in this application is as follows:

[0031] The sensor unit monitors parameters such as the motorcycle's speed, engine speed, and gearshift signals, and transmits these parameters to the control unit. Based on these parameters, the control unit uses a pre-set algorithm to determine the current driving state and, in turn, controls the actuator unit to operate the clutch accordingly. The actuator unit is connected to the motorcycle's clutch and can engage and disengage the clutch according to commands from the control module.

[0032] When the motorcycle starts, the sensor unit transmits information such as vehicle speed and engine speed to the control unit. The control unit determines the current state and engages or disengages the clutch according to the control logic. The process begins with the engine idling. A gear is engaged without manual clutch operation. The accelerator is turned to start the motorcycle. The control unit determines that the vehicle is in motion and controls the actuator unit to gradually engage the clutch, ensuring smooth driving. During driving, if the vehicle speed decreases or a gear change is required, the control unit, based on the parameters transmitted by the sensor unit, promptly controls the actuator unit to disengage the clutch, ensuring smooth gear changes and preventing vehicle jerk.

[0033] In the above structure, the specific structure and operating principle of the clutch actuator push rod 3 driving the clutch to separate or engage are prior art in this field. The improvement of the present application mainly lies in the structure of driving the clutch actuator push rod 3 to act. Since the present embodiment adopts the above scheme, by setting up a dual-motor drive, the probability of servo motor failure can be avoided and the stability of the automatic drive control module can be improved. In terms of structure, there is no need to change the existing clutch structure, and only the clutch control device of the present application needs to be installed. The structure is simple and the modification of existing vehicles is simple.

[0034] Preferably, in this embodiment, the first drive motor and the second drive motor are disposed adjacent to each other and on the same side as the clutch swing arm 2. Furthermore, the transmission assembly 5 of the present application includes multiple stages of driven teeth, which are arranged parallel to each other. With this structure, the overall structure of the clutch control device is compact, which helps reduce the overall size of the clutch control device.

[0035] like Figure 5 As shown, the transmission assembly 5 in this embodiment includes a driving tooth 51 and a multi-stage driven tooth. The driving tooth 51 is arranged on the output shaft of the drive motor 4. The driving tooth 51 on the output shaft of the first drive motor and the second drive motor meshes with the same driven tooth for transmission. This structure enables the first drive motor and the second drive motor to be connected to the same set of transmission assembly 5. In addition, the multi-stage driven teeth are arranged parallel to each other, and the central rotation axis of the driven teeth is arranged parallel to the output shaft of the drive motor 4 and the central axis of the clutch actuator rod 3. The use of parallel tooth transmission makes the transmission assembly 5 more compact. At the same time, the parallel tooth transmission has a higher transmission efficiency, can reduce energy loss, and improve fuel economy; and the parallel teeth have high meshing accuracy, can ensure the smoothness and accuracy of power transmission, and reduce noise and vibration.

[0036] In this embodiment, there are four transmission teeth, including the first driven tooth 52 to the fourth driven tooth. The driving tooth 51 fixed to the output shaft of the drive motor 4 meshes with the first driven tooth 52, the first driven tooth 52 meshes with the second driven tooth 53, the second driven tooth 53 meshes with the third driven group, the third driven tooth 54 meshes with the fourth driven tooth 55, and the fourth driven tooth 55 is fixed on the clutch actuator rod to drive the clutch actuator rod to rotate synchronously. The above scheme uses the driving tooth 51 and multiple driven teeth to form a power transmission chain, forming a power transmission mechanism. The number of teeth, module and other parameters of the driven teeth cooperate with the driving tooth 51 to achieve the required transmission ratio. In this embodiment, multiple driven teeth share the load, so that the force borne by each driven tooth is relatively reduced, reducing the risk of deformation and damage of a single gear due to excessive load, thereby improving the stability of the entire transmission system. By adjusting the number of teeth and position relationship of different driven teeth, the four driven teeth can achieve a more precise transmission ratio. The distribution of the four driven teeth makes the transmission process smoother, reducing the noise and vibration caused by the uneven meshing of individual gears. In addition, the smooth transmission can also extend the service life of the gears and reduce maintenance costs.

[0037] The clutch control device of this embodiment includes a housing 1, a transmission assembly 5 is located in the housing 1, and a connection hole for connecting with a vehicle body is provided on the housing 1. The clutch control device can be mounted on the vehicle body through the housing 1.

[0038] The clutch control device of this embodiment also includes a clutch handle 71 and a hydraulic pump 7, and the clutch is manually opened and closed by the clutch handle 71 and the hydraulic pump 7. Figure 6 As shown, the clutch handle 71 is connected to the oil pot 72 of the hydraulic pump 7. Operating the clutch handle 71 compresses the hydraulic oil in the oil pot 72, causing the pressure signal output by the hydraulic pump 7 to change; the pressure signal transmission interface 73 of the hydraulic pump 7 is connected to the control unit 8 of the automatic drive module, and the control unit 8 is used to control the automatic drive module according to the pressure signal output by the hydraulic pump 7.

[0039] The operating principle of control via the clutch handle 71 and hydraulic pump 7 is as follows: When the driver squeezes the clutch handle 71, the volume of hydraulic oil in the hydraulic pump 7 is compressed. However, due to the near-impossibility of hydraulic oil to be compressed, power transmission is more efficient. When the hydraulic oil is compressed, a pressure value is generated. Once the pressure reaches a predetermined range, this pressure value is transmitted via a signal transmission interface to the control unit 8, which in this embodiment is the ECU. When the driver releases the clutch handle, the fluid pressure in the clutch hydraulic pump 7 is restored, and a zero signal is transmitted to the ECU. The ECU can then control the automatic drive module to perform different actions based on the different hydraulic signals detected from the hydraulic pump 7, thus achieving manual clutch opening and closing control.

[0040] like Figure 7 As shown, the clutch in this embodiment has an automatic control mode and a manual control mode. When the clutch handle 71 is not operated, the automatic control mode is executed by default. In the automatic control mode, the control unit 8 automatically determines whether it is necessary to control the clutch to be disengaged or engaged through the vehicle operating parameters fed back by the sensor unit. After operating the clutch handle to make the hydraulic pump 7 generate a pressure signal that is not 0, the clutch is switched to manual control mode. In the manual control mode, the control unit 8 directly drives the drive motor in the automatic drive module to work and drive the clutch to open and close; after detecting that the pressure from the hydraulic pump 7 returns to 0, the manual control mode ends and enters the automatic control mode.

[0041] Therefore, according to the above-mentioned clutch handle 71 and hydraulic pump 7, the hydraulic pump 7 and the linear switch can cooperate to output high-frequency electronic signals to the ECU to control the clutch, replacing the traditional cable mechanical structure, which can effectively reduce the volume of the automatic clutch actuator and reduce the weight to facilitate the layout of the entire vehicle.

[0042] Another embodiment of the present application provides a motorcycle, which includes a manual and automatic dual-purpose clutch control device as described in any of the above embodiments, wherein the clutch control device is installed on one side of the clutch, and the clutch execution push rod 3 is connected to the clutch.

[0043] Example 2:

[0044] like Figure 8 As shown, this embodiment differs from embodiment 1 in that a hydraulic pump is not provided, but a clutch cable and a clutch swing arm 2 are provided instead. The clutch cable connects the clutch handle and the clutch swing arm 2, and the clutch swing arm 2 is fixed to the clutch actuator push rod 3, directly driving the clutch actuator push rod 3 to move. This embodiment retains the traditional cable mechanical structure. Even if the automatic drive module partially fails, the clutch push rod can be manually driven to move through the clutch handle and clutch cable, without relying on the drive motor, transmission assembly and other structures to drive the clutch push rod. This avoids the clutch system from being paralyzed due to a partial failure of the automatic drive module, and ensures the stability of the vehicle clutch system.

[0045] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
