[0024] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Embodiments of the present utility model will be described in detail below.

[0025] Reference is made below to Figure 1 Describe the clutch control device according to an embodiment of the present utility model.

[0026] Refer to Figure 1 As shown, the clutch control device 100 according to the first aspect embodiment of the present utility model includes: a clutch slave cylinder 10, a fork assembly 20, and a driving mechanism 30. The fork assembly 20 is connected to the clutch slave cylinder 10. The driving mechanism 30 is disposed outside the cab of the vehicle, and the driving mechanism 30 is connected to the clutch slave cylinder 10. The driving mechanism 30 selectively drives the fork assembly 20 to move through the clutch slave cylinder 10.

[0027] Specifically, in a traditional clutch control device, a clutch pedal is generally provided at the main driver position of the vehicle. The driver can only operate the clutch pedal at the main driver position to control the engagement and disengagement of the clutch. When leaving the cab, the driver will be unable to operate. However, the driver usually needs to get out of the vehicle to operate the upper-mounted equipment, so the driver cannot control the disengagement and engagement of the clutch under the vehicle.

[0028] Therefore, it is necessary to optimize the design of the clutch control device 100. The clutch control device 100 mainly consists of a clutch slave cylinder 10, a fork assembly 20, and a driving mechanism 30. Among them, the driving mechanism 30 is disposed outside the cab. For example, the driving mechanism 30 can be disposed on the vehicle frame outside the cab. The driving mechanism 30 is connected to the clutch slave cylinder 10. In this way, the driving mechanism 30 can control the clutch slave cylinder 10 to work.

[0029] The driving mechanism 30 can selectively drive the fork assembly 20 to move through the clutch slave cylinder 10. That is to say, when the driver needs to control the clutch disengagement outside the cab, the driving mechanism 30 can be operated to drive the clutch slave cylinder 10 to work. The clutch slave cylinder 10 drives the fork assembly 20 to move, so that the pressure plate and the friction plate of the clutch can be separated. When the clutch needs to be engaged, the driver can operate the driving mechanism 30 outside the cab to make the fork assembly 20 return to the initial position, so that the pressure plate and the friction plate of the clutch can be engaged.

[0030] Thus, the clutch control device 100 can enable the driver to disengage or engage the clutch outside the cab, which is convenient for the driver to operate outside the vehicle.

[0031] According to some embodiments of the present invention, the driving mechanism 30 includes an oil storage tank, an oil pump and a controller. One end of the oil pump is connected to the oil storage tank, and the other end of the oil pump is connected to the clutch slave cylinder 10. The controller is electrically connected to the oil pump for controlling the start and stop of the oil pump.

[0032] Among them, the oil pump in the driving mechanism 30 is located between the oil storage tank and the clutch slave cylinder 10. In this way, the oil pump can provide power for the oil in the oil storage tank to enter the clutch slave cylinder 10. Since the clutch slave cylinder 10 is connected to the fork assembly 20, the clutch slave cylinder 10 can control the movement of the fork assembly 20 to achieve the disengagement of the clutch.

[0033] Furthermore, the controller is electrically connected to the oil pump, so that the controller can control the start and stop of the oil pump, and thus can control the flow rate of the oil between the oil storage tank and the clutch slave cylinder 10.

[0034] According to some embodiments of the present invention, the clutch control device 100 further includes a first valve body 31. The first valve body 31 is connected between the oil pump and the clutch slave cylinder 10, and the first valve body 31 is electrically connected to the controller.

[0035] Among them, the first valve body 31 is connected between the oil pump and the clutch slave cylinder 10. In this way, the first valve body 31 can control the on-off of the oil between the oil pump and the clutch slave cylinder 10.

[0036] According to some embodiments of the present invention, as Figure 1 shown, the clutch control device 100 further includes a clutch pedal 32 and a clutch master cylinder 33. One end of the clutch master cylinder 33 is connected to the clutch pedal 32, and the other end of the clutch master cylinder 33 is connected to the first valve body 31 through a pipeline. Among them, the first valve body 31 is a three-way valve.

[0037] Specifically, when the driver is in the cab, one end of the clutch master cylinder 33 is connected to the clutch pedal 32, and the other end of the clutch master cylinder 33 is connected to the first valve body 31 through a pipeline. The oil cup 35 is connected to the clutch master cylinder 33 through a pipeline, and the oil cup 35 can supply hydraulic fluid to the clutch master cylinder 33. When the driver steps on the clutch pedal 32, the clutch master cylinder 33 can deliver the hydraulic fluid to the first valve body 31, and the first valve body 31 can be opened under the pressure of the hydraulic fluid. Since the first valve body 31 is a three-way valve and is respectively connected to the clutch master cylinder 33, the clutch slave cylinder 10 and the oil pump pipeline, thus, when the hydraulic fluid of the clutch master cylinder 33 is delivered to the first valve body 31, the oil pressure can open the oil circuit between the first valve body 31 and the clutch slave cylinder 10, so that the hydraulic fluid of the first valve body 31 can enter the clutch slave cylinder 10, and the clutch slave cylinder 10 can drive the fork assembly 20 to move, thereby separating the pressure plate and the friction plate of the clutch in the cab.

[0038] According to a specific embodiment of the present invention, as Figure 1 shown, the clutch control device 100 further includes: an air storage tank 34. The clutch slave cylinder 10 has an air inlet 11, an air inlet valve and a piston rod. The air inlet valve is connected to the oil pump, the air inlet valve is movably arranged at the air inlet 11, and the air inlet valve is adapted to open the air inlet 11 under the pressure of the hydraulic fluid delivered by the oil pump. The air inlet 11 is connected to the air storage tank 34, and the piston rod is connected to the fork assembly 20.

[0039] Specifically, when the hydraulic fluid in the oil storage tank of the driving mechanism 30 is delivered under the oil pump pressure, the first valve body 31 can be opened, and the hydraulic fluid passes through the first valve body 31, so that the hydraulic fluid enters the clutch slave cylinder 10 under the oil pressure provided by the oil pump.

[0040] Since the clutch slave cylinder 10 has a master cylinder and an assist cylinder, the hydraulic fluid first reaches the oil chamber of the assist cylinder of the clutch slave cylinder 10. At this time, the hydraulic fluid has two directions. One is to push the master cylinder piston connected to the piston rod, and the other is to push the relay piston to move the air inlet valve to open, so that the air inlet 11 can be opened. The compressed air in the air storage tank 34 flows into the air chamber of the assist cylinder through the air inlet 11. At this time, under the simultaneous action of the air pressure and the hydraulic pressure, the piston rod can be pushed out.

[0041] Since the piston rod is connected to the fork assembly 20, the fork assembly 20 includes: a fork 21 and a release bearing 22. One end of the fork 21 is connected to the piston rod, and the other end of the fork 21 is connected to the release bearing 22. The piston rod of the clutch slave cylinder 10 drives the fork 21 to move, pushing the release bearing 22 forward, thereby separating the pressure plate and the friction plate of the clutch outside the cab.

[0042] According to some embodiments of the present utility model, the clutch control device 100 further includes: a position detector and an indicator. The position detector is used to detect the position of the piston rod, and the position detector is connected to the controller. The indicator is electrically connected to the controller. When the position of the piston rod moves to a predetermined position, the indicator emits an indication message according to the instruction of the controller.

[0043] Wherein, when the piston rod moves to the position where the pressure plate and the friction plate of the clutch are separated, the position detector can detect the position of the piston rod at this time. Since the position detector is electrically connected to the controller, the position detector can feedback the detected position information of the piston rod at this time to the controller. Since the indicator is electrically connected to the controller, the indicator emits an indication message according to the instruction of the controller, so that it can be determined that the pressure plate and the friction plate of the clutch are in a separated state.

[0044] According to a specific embodiment of the present utility model, the position detector includes: a second valve body, a return air pipe 13 and a gas sensing element. The clutch slave cylinder 10 further has a return air port 12. The second valve body is arranged at the return air port 12. When the position of the piston rod moves to a predetermined position, the piston rod contacts the second valve body, so that the second valve body can open the return air port 12. One end of the return air pipe 13 is connected to the return air port 12, one end of the gas sensing element is connected to the other end of the return air pipe 13, and the other end of the gas sensing element is electrically connected to the controller.

[0045] Wherein, the piston rod moves to a predetermined position. At this time, the pressure plate and the friction plate of the clutch are in a separated state, and the piston rod triggers the second valve body, so that the second valve body can open the return air port 12. Also, one end of the return air pipe 13 is connected to the return air port 12, the gas at the return air port 12 enters from one end of the return air pipe 13, and the gas passes through the other end of the return air pipe 13 and enters the gas sensing element. Since the other end of the gas sensing element is electrically connected to the controller, the gas sensing element can feedback the information to the controller. The indicator is electrically connected to the controller, and the indicator can be set as an indicator light. By the indicator light being on, it can be determined that the pressure plate and the friction plate of the clutch are in a completely separated state.

[0046] According to a specific embodiment of the present utility model, the gas sensing element is a check valve. The check valve is electrically connected to the controller. The check valve is provided with a switch. When the check valve is opened, the switch is triggered, and the controller detects that the switch is in an open state, and the indicator light is on.

[0047] Specifically, the gas sensing element can be set as a check valve. When the gas at the return air port 12 flows into the check valve through the return air pipe 13, the check valve is opened by the air pressure. At the same time, the check valve is provided with a switch. When the check valve is opened, the switch is triggered, and the controller detects that the switch is in an open state. Since the controller is electrically connected to the indicator, the indicator light is on, so that it can be determined that the pressure plate and the friction plate of the clutch are completely separated.

[0048] According to some embodiments of the present utility model, the drive mechanism 30 further includes: a control switch, and the control switch is disposed on the controller.

[0049] Wherein, the arrangement of the control switch on the controller can facilitate the controller to control the oil pump and other components.
