Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1-2 illustrate some embodiments according to the invention.
Referring to fig. 1 to 2, the electrically controlled clutch device is composed of a valve plate body 11, a plug-in two-position three-way electromagnetic directional valve 12, a throttle speed regulating valve 13 and a safety valve 14. The throttle speed regulating valve and the electromagnetic reversing valve are coaxially arranged in the valve plate body in a left-right mode.
The valve plate body 11 is internally provided with a vertically extending oil duct 4 (namely a working oil duct), the outlet of the oil duct 4 is connected with the clutch power cylinder, the oil duct 4 is communicated with an oil duct 5 which horizontally extends in the lateral direction, the oil duct 5 is provided with a plug-in safety valve 14, the safety valve 14 is communicated with the oil duct 6 when opened, and the oil duct 6 is communicated with an oil return opening T1.
The oil passage 4 is communicated with another vertically extending oil passage 2 (i.e. a transition oil passage), and a starting end of the oil passage 2 is provided with a process plug. The plug-in type two-position three-way electromagnetic directional valve 12 is laterally installed on the oil duct 2, and when the electromagnetic directional valve 12 is powered on, the oil duct 1 (namely an oil inlet duct) for providing hydraulic oil is communicated with the oil duct 2, and the oil inlet of the throttle speed regulating valve 13 is cut off.
When the electromagnetic directional valve 2 is in power failure, the oil duct 1 is disconnected from the oil duct 2, and the oil duct 2 is communicated with an oil inlet of the throttling speed regulating valve 13.
The electromagnetic clutch device is a clutch power cylinder control valve plate, and is combined with other function valve plates such as an oil inlet valve plate, an oil return valve plate, a reversing valve plate and the like to form a multi-valve plate type hydraulic control valve group.
The working process of the electric control clutch device is as follows:
when the electromagnetic valve is electrified, high-pressure oil is switched to the oil duct through the oil duct 1, is rapidly pushed out of the clutch power-assisted oil cylinder through the oil duct 2 and the oil duct 4, and the high-pressure oil (for example, 3MPa) enters the oil return through the oil duct 5, the safety valve is opened, and the oil return is carried out through the oil duct 6. When the electromagnetic valve is powered off, oil of the clutch power-assisted oil cylinder enters the electromagnetic valve through the oil duct 4 and then flows into the oil duct 2, and at the moment, the oil of the oil duct 2 passes through the speed regulating valve, is combined by micro-motion buffering and then flows into the oil duct 3 to enter return oil. Therefore, the clutch assisting operation has the characteristics of quick clutch separation and buffering combination.
In one embodiment, the triggering of the control element (such as a travel switch and a sensor) of the solenoid valve, which loses power, is associated with the action of the clutch pedal, when the clutch pedal is pressed, the travel switch is triggered, so that the solenoid valve is powered on, the clutch is opened by the aid of the power assisting of the clutch power assisting oil cylinder, and after the clutch pedal is released, the solenoid valve loses power, the clutch is in buffering combination, the function of shifting without pressing the clutch (only pressing the clutch pedal) is realized, and the operation intensity of an operator is greatly reduced.
In another embodiment, the control element (such as a switch button and a sensor) for controlling the electromagnetic valve to be powered off is controlled by manual operation, so that the function of not stepping on the clutch is realized, and the left foot of an operator is liberated.
In yet another embodiment, a first control element for de-energizing the foot clutch control solenoid and a second control element for de-energizing the manual clutch control solenoid are provided simultaneously. The first and second control elements both control the solenoid valve to be energized when activated. The use of the first control element inherits the driving operation habit of an operator, and the use of the second control element enables the clutch operation to be flexible and changeable.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
