The displacement passed by by piston, the task replacement above provided or additionally thus solve：For transmission device or piston configuration one
Displacement detector.The displacement detector is used to detecting the displacement actually passed by, the displacement then by the Displacement Ratio with being known compared with.
Brief description of the drawings
The present invention further advantage, feature and details by being learnt in following specification, in the following description by
Accompanying drawing explains in detail different embodiments.
Cartesian coordinate line chart is shown in unique accompanying drawing 1, having for control according to the present invention is illustrated by it
The method of the clutch of hydrostatic actuator.
Embodiment
One cartesian coordinate line chart is shown in accompanying drawing 1, there is x-axis 1 and y-axis 2.In y-axis 2 with suitable pressure unit,
Such as bar draws the pressure of active cylinder.Active cylinder contains hydraulic medium, such as hydraulic oil, and it is loaded by the piston in active cylinder
With pressure.Active cylinder is connected by underground with the slave cylinder of hydraulic clutch steerable system.
When piston moves in the axial direction in active cylinder, the pressure change in active cylinder.The motion of piston in the axial direction
Caused by the rotation of turn-screw, the turn-screw is coupled by transmission device with piston rod, and the piston rod is from active cylinder
Piston stretches out.The rotary motion of turn-screw is converted into by axial movement of the piston in active cylinder by the transmission device.It is living
The motion of plug is drawn in the form of displacement by suitable displacement unit, such as millimeter in x-axis 1 in Fig. 1 coordinate line chart.
The clutch indicatrix 10 of clutch, the clutch control that clutch passes through hydraulic pressure are shown in the coordinate line chart
System manipulation.Drive motor collectively constitutes the clutch actuator of hydraulic pressure with turn-screw, transmission device, piston and active cylinder.
Clutch indicatrix 10 includes characteristic curve branch 11, and it describes the situation of new clutch.The description mill of characteristic curve branch 12
The situation of the clutch of damage.For the clutch of abrasion, larger stroke is needed to manipulate clutch due to the abrasion of friction lining
Device.
The rotary motion of turn-screw is detected by rotor-position sensor, and the rotor-position sensor is embodied as angle
Sensor.Linear displacement transducer can be additionally used, for detecting piston displacement.Torque on clutch ideally with cause
Improve with moving the proportional pressure in device active cylinder.The proportionate relationship between pressure and clutch torque in active cylinder can be used
In the displacement for trying to achieve piston.
In clutch operation, the skidding between turn-screw and transmission device can cause the skew of offset axis 1.The worst
In the case of the skew can cause undesirably to be moved in the backstop 15 of turn-screw.Being moved in the backstop 15 can cause to activate
The damage of device.Especially this danger be present when being moved in being run in clutch on an exploration position 14.
Exploration refers to a process, and in this process, piston is returned in active cylinder in an extreme position, to release
Put at least one connecting hole between active cylinder and equalizing reservoir.It can realize that active cylinder is flat with this by the connecting hole being released
Pressure balance between weighing apparatus container.
The given displacement 5 that setting pressure 4 corresponds in x-axis 1.In order to prevent in the case where being moved on exploration position 14
Undesirably reach backstop 15, provided with a displacement detector 18.This is moved to all the time when being moved on the exploration position 14
On displacement detector 18.
See in Fig. 1, sound out position 14 and be arranged between backstop 15 and displacement detector 18.Pass through skew in Fig. 1
Offset axis 21 represent the displacement bias after sliding motion.The backstop 15 of turn-screw and displacement detector 18 bit shift
Put on offset axis 1 be consistent on the offset axis 21 after skew.
But by the double-head arrow 24 corresponding to corrected range, sound out position and offset by.On offset axis 21 after skew
Exploration position 34 after skew moves a corrected range 24 relative to position 14 is soundd out.When closing clutch next time,
Corrected range 24 is considered by given displacement 5, revised given displacement 35 is thus obtained on the offset axis 21 after skew.
Therefore, the manipulation of displacement detector 18 is leading on exploration position 14 is moved in the case where occurring sliding
The great-jump-forward of offset axis is caused to retract so that the exploration position that can be non-dangerously moved to after skew by rotor-position sensor
On 34.When closing clutch next time, corrected range 24 is removed from set-point in displacement pre-control, it is last to reach
The pressure regulation spectrum learnt.
