Description of drawings
Other advantage of the present invention, feature and details are explained different embodiments by accompanying drawing in the following description in detail by learning in the following specification.
At cartesian coordinate line chart shown in unique accompanying drawing 1, illustrate according to the method that has the clutch of hydrostatic actuator for control of the present invention by its.
Embodiment
A cartesian coordinate line chart shown in the accompanying drawing 1 has x axle 1 and y axle 2.On y axle 2 with the pressure unit that is fit to, the pressure that for example bar draws active cylinder.Active cylinder contains hydraulic medium, hydraulic oil for example, and it is loaded with pressure by the piston in the active cylinder.Active cylinder is connected by the slave cylinder of underground with the hydraulic coupling control system.
When piston moved in active cylinder in the axial direction, the pressure in the active cylinder changed.The piston rotation that moves through turn-screw in the axial direction causes that this turn-screw is by transmission device and piston rod coupling, and this piston rod stretches out from the piston of active cylinder.Convert rotatablely moving of turn-screw the axial motion of piston in active cylinder to by this transmission device.The motion of piston with the form of displacement by the displacement unit that is fit to, draw such as the x axle 1 of millimeter in the coordinate line chart of Fig. 1.
At the clutch indicatrix 10 of clutch shown in this coordinate line chart, clutch is handled by the clutch operating system of hydraulic pressure.Drive motor and turn-screw, transmission device, piston and active cylinder form the clutch actuator of hydraulic pressure jointly.Clutch indicatrix 10 comprises characteristic curve branch 11, and it describes the situation of new clutch.The situation of the clutch of wearing and tearing is described by characteristic curve branch 12.For the clutch of wearing and tearing, the wearing and tearing that serve as a contrast owing to friction need larger stroke to come controlled clutch.
Rotatablely moving of turn-screw detects by rotor-position sensor, and this rotor-position sensor is embodied as angle transducer.Additionally can use linear displacement transducer, for detection of piston displacement.Torque on the clutch ideally with the actuator active cylinder in pressure improve pro rata.Pressure in the active cylinder and the proportionate relationship between the clutch torque can be used for trying to achieve the displacement of piston.
In service at clutch, skidding between turn-screw and the transmission device can cause the skew of offset axis 1.Under worst case, should skew can cause moving to undesirably on the backstop 15 of turn-screw.Move to the damage that can cause actuator on this backstop 15.Especially when moving to one and have this danger when souning out on the position 14 in that clutch being in service.
Exploration refers to a process, and in this process, piston returns in active cylinder in the limit position, in order to discharge at least one attachment hole between active cylinder and the equalizing reservoir.Can realize pressure balance between active cylinder and this equalizing reservoir by d/d attachment hole.
Setting pressure 4 is corresponding to the given displacement 5 on the x axle 1.In order to prevent in situation about moving on the exploration position 14, reaching undesirably backstop 15, be provided with a displacement detector 18.All the time to move on this displacement detector 18 in the time of on moving to this exploration position 14.
In Fig. 1, see, sound out position 14 and be arranged between backstop 15 and the displacement detector 18.In Fig. 1 by the displacement bias behind the offset axis 21 expression sliding movements that have been offset.The backstop 15 of turn-screw and displaced position displacement detector 18 are consistent with offset axis 21 after skew on offset axis 1.
But by the double-head arrow 24 corresponding to corrected range, sound out the position and be offset.A corrected range 24 has been moved with respect to souning out position 14 in exploration position 34 after the skew on the offset axis 21 after the skew.When closed clutch next time, consider corrected range 24 by given displacement 5, the offset axis after skew 21 obtains revised given displacement 35 thus.
Therefore, this manipulation of displacement detector 18 causes the jump type of offset axis to be retracted before souning out on the position 14 moving in the situation of occur sliding, so that can move to non-dangerously on the exploration position 34 after the skew by rotor-position sensor.When closed clutch next time, in the displacement pre-control, from setting value, remove corrected range 24, in order to reach the pressure regulation range of learning at last.
