On the end face of clutch plunger；Eddy current displacement sensor is threaded into connector sleeve, until end face and mobile bar flange-type
Head end fitting after and tight locking nut, Eddy current displacement sensor is fixed；Displacement sensor connecting line passes through transmission shaft
On threading hole export to the outside of gear-box；
After clutch oil cylinder oil suction chamber is passed through pressure oil, clutch plunger is gradually moved to the left pressure under the action of pressure oil
Friction-tight piece group, mobile bar also follow piston closely and are moved to the left, Eddy current displacement sensor measures at this time under holddown spring effect
End face and the distance between end face be exactly clutch plunger moving distance.
As preferred: flat gesture of the pressure oil leaked at the mobile bar and cylinder body cooperation through mobile club head, into
Enter in the cavity where holddown spring, and under the action of clutch rotary centrifugal force, is thrown away from oil leak hole, make the chamber always
Under low-pressure state, avoids displacement sensor and contacted with the direct of high temperature high pressure oil in cylinder body, make it to work normally.
The present invention, which has, has not only carried out effective partition for sensor and in-oil cylinder high temperature and pressure oil liquid, greatly improves
The working environment of sensor, while the features such as measurement accuracy can also be improved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail: shown in Fig. 1, a kind of hydraulic clutch of the present invention
The measuring mechanism of piston displacement, mainly by clutch oil cylinder body 4, mobile bar 5, holddown spring 6, threaded connecting sleeve 7, locking spiral shell
Female displacement sensor 9, the transmission shaft 11 with threading hole B form；Mobile piston 3 is installed inside the cylinder body 4, is being leaned on
It is machined with the mounting hole for placing sensor 9 on the end wall of nearly piston 3, and has the radial oil leak hole A of connection therewith；
The mobile bar 5 is made of the bar portion and flange-type head of minor diameter, the aperture opened up in bar portion and cylinder body 4
Cooperation forms clearance seal, and the top of bar portion is contacted with 3 end face of clutch plunger；The head flanges of mobile bar 5 are equipped with step,
Play the role of support and positioning compression spring, and circumferentially has flat gesture everywhere；
The internal screw thread that the threaded connecting sleeve 7 is machined with the external screw thread coupled with cylinder body 4 and couples with sensor 9, interior
Rank hole can accommodate holddown spring 6；
The transmission shaft 11 is equipped with the axial hole and radial hole of perforation, the axial direction that the joint lines of sensor 9 pass through the perforation
Hole and radial hole are drawn from the inside of gear-box；Clutch oil cylinder body 4 is fixedly connected with transmission shaft 11.
A kind of measurement method of the measuring mechanism using hydraulic clutch piston displacement, the measurement method is:
When clutch oil cylinder oil suction chamber E is not passed through operating pressure oil, clutch plunger 3 under the action of clutch return spring 1,
Right side is close on the end face of clutch oil cylinder body 4, and also under the action of holddown spring 6, bar portion presses closer mobile bar 5 at this time
On the end face of clutch plunger 3；Eddy current displacement sensor 9 is threaded into connector sleeve 7, until end face C and end face D is bonded
(i.e. elimination mobile bar 5 and Eddy current displacement sensor 9 measure the gap between head) afterwards and tight locking nut 8, by eddy current
Displacement sensor 9 is fixed；Displacement sensor connecting line 10 exports to the outside of gear-box by the threading hole B on transmission shaft 11.
After clutch oil cylinder oil suction chamber E is passed through pressure oil, clutch plunger 3 is under the action of pressure oil, gradually to the left
Mobile pressing friction piece group 2, mobile bar 5 also follow piston closely and are moved to the left under the effect of holddown spring 6, and eddy current is displaced at this time
The distance between end face C and end face D that sensor 9 measures are exactly the moving distance of clutch plunger 3.Mobile bar 5 and cylinder body 4
