To make the stress equalization of fastener 3, shift fork 41 may be configured as multiple (three being provided with the present embodiment, such as Fig. 2), enclose
Around the arranged for interval of annular groove 31.But the present invention is not limited thereto, shift fork 41 may be arranged as more.
In present embodiment, drive mechanism 4 also includes the housing 43 being fixed in frame, and housing 43, which has, surrounds fastener
3 toroidal cavity, drive mechanism 4 also includes being connected with driver and being arranged on the mobile dish 42 in the toroidal cavity, mobile dish
42 be specially the annular disk with toroidal cavity shape adaptation, can move axially, is provided with mobile dish 42 in toroidal cavity
The shift fork 41 extended towards fastener 3, mobile dish 42 are moved under the driving of driver, so as to drive shift fork 41 to move.
It is arranged to drive the driver that mobile dish 42 are moved to specifically include in the toroidal cavity of housing 43 and difference
Compression spring 44 and telescopic air spring 45 positioned at the both sides of mobile dish 42, compression spring 44 are used to apply mobile dish 42
Axial thrust, air spring 45 can overcome the axial thrust and control the decrement of compression spring 44.Specifically, to air bullet
Spring 45 is inflated, and air spring 45 gradually extends, and compression spring 44 is gradually compressed in the presence of air spring 45, mobile dish 42
It is moved to the left;When air spring 45 is exhausted, air spring 45 shortens, and compression spring 44 gradually extends, mobile dish 42
Moved right under the axial thrust effect of compression spring 44.It is appreciated that the driver for promoting mobile dish 42 to move is not limited
In compression spring 44 and air spring 45 set by the both sides of mobile dish 42, also it can control to move by such as hydraulic pressure or the mode such as pneumatic
Moving plate 42 is moved back and forth.
It is the annular disk being adapted to toroidal cavity because of mobile dish 42, to make annular disk be moved in the case of uniform force,
Compression spring 44 can be set it is multiple, along the toroidal cavity circle spacing arrange.
In present embodiment, driver also includes being used to detect the clutch state sensor of the location status of fastener 3, with
Just the location status that the fastener 3 of conjunction state sensor acquisition is conducted away from according to controls the movement of shift fork 41.The clutch
State sensor can be electrically connected with the control unit of the equipment of the arrangement of clutch provided using the present invention, and control unit is received and come from
In the electric signal of the expression location status of fastener 3 of the clutch state sensor, and then shift fork 41 is controlled to move.
Preferably, the clutch state sensor is the linear transducer set in the toroidal cavity of housing 43, the length
Sensor is used for the length for obtaining the air spring 45, and fastener 3 is judged by obtaining the length information of air spring 45
Location status, be connected with air spring 45 and be additionally provided with magnetic valve, linear transducer and magnetic valve are electrically connected with control unit
Connect, linear transducer sends the length information of the air spring 45 of acquisition to control unit, and control unit is believed according to the length
Breath judges the location status of fastener 3, the signal that air spring 45 is inflated or is vented then is sent to magnetic valve, by magnetic valve
Control the inflation or exhaust of air spring 45.
When in the hydraulic power-assist steering system that the arrangement of clutch that the present invention is provided is applied to vehicle, power-assisted oil pump and driving
The detailed process that the power source of the power-assisted operation of oil pump carries out clutch is following (with reference to Fig. 1):
When normal vehicle operation need not be turned to, gassy in air spring 45, compression spring 44 is in air spring 45
In the presence of compressed, the connector 2 of fastener 3 and second be in released state, power-assisted oil air pump inoperative.
When Vehicular turn, control unit sends the signal being vented to air spring 45 to magnetic valve, and solenoid valve control is empty
Gas spring 45 is vented, and air spring 45 is gradually shortened, and compression spring 44 extends, mobile dish 42 in the presence of compression spring 44 to
Move right, shift fork 41 promotes fastener 3 gradually to be engaged with the second connector 2, meanwhile, linear transducer obtains air spring in real time
45 length information simultaneously sends the length information to control unit, and control unit judges fastener 3 and according to the length information
Whether two connectors 2 are sufficiently engaged with, and shorten to a certain extent in air spring 45, and fastener 3 is sufficiently engaged with the second connector 2
When, power-assisted oil pump is with driving the power source of the power-assisted operation of oil pump to be connected, power-assisted operation of oil pump, now, and control unit is to electromagnetism
Valve sends the signal for stopping exhaust, and solenoid valve control air spring 45 stops exhaust.
When vehicle stops turning to, control unit sends the signal inflated to air spring 45, magnetic valve control to magnetic valve
Air spring 45 processed is inflated, and compression spring 44 is compressed in the presence of air spring 45, and mobile dish 42 drive shift fork 41 to the left
Mobile, shift fork 41 promotes fastener 3 gradually to be separated with the second connector 2, meanwhile, linear transducer obtains air spring 45 in real time
Length information and send the length information to control unit, control unit judges fastener 3 and second according to the length information
Whether connector 2 is separated, and certain length, when fastener 3 is separated with the second connector 2, power-assisted oil pump are reached in air spring 45
With driving the power source of the power-assisted operation of oil pump to separate, power-assisted oil pump is stopped, now, and control unit is sent to magnetic valve stops
The signal only inflated, solenoid valve control air spring 45 stops inflation.
Herein it should be noted that, when vehicle air supply system break down when, air spring 45 can not be inflated, and at this moment be compressed
Spring 44 extends, and fork 41 can promote fastener 3 move right in the presence of compression spring 44, make the first connector 1 and the
Two connectors 2 are bonded together, so, even if the air supply system of vehicle breaks down or other reasons, the nothing of air spring 45
When method is inflated, the steering that power-assisted oil pump remains able to be connected as vehicle with power source provides power-assisted.
