Clutch main body of the present invention and relative position schematic diagram of the clutch cap under discrete state, the main work of freewheel clutch of the present invention
It is as follows to make principle：
It is (as shown in Figure 3) that clutch main body 1 enters the operation principle engaged with clutch cap 5：
1) original state, cam 11, roller 14 and backing ring 12 are opposing stationary；
2) in the moment for surging the starting of arbor 3, cam 11 rotates clockwise therewith, and backing ring 12 is still kept with roller 14 at this time
Static, under relative motion and inertia force effect, roller 14 is pushed by cam 11 and is constrained simultaneously by backing ring 12, from point of cam 11
16 plane of higher region of engagement is risen to from 17 plane of area, contacted with clutch cap 5 and enters engagement；
3) clutch main body 1 is engaged with clutch cap 5, forms the torque transmitting assembly of a synchronous rotary.
The operation principle that clutch main body 1 is disengaged with clutch cap 5 is (as shown in Figure 4)：
When clutch cap 5 rotates very fast relative to clutch main body 1, under the action of frictional force, clutch cap 5 drives roller 14
From the region of engagement of cam 11,16 plane falls on 17 plane of lower Disengagement zone, and roller 14 is disengaged with clutch cap 5, clutch master
Body 1 is no longer engaged with clutch cap 5.
Clutch main body 1 of the present invention uses non-spring structure, by the opposite fortune between cam 11 and backing ring 12, roller 14
It is dynamic realize with clutch cap engage and disengagement.It is as follows in meshing state power transmission line：Under hydraulic motor drive mode, power by
The axis 3 of hydraulic motor exports, and by two flat keys 2, is transmitted to cam 11, then passes to clutch cap 5 by roller 14, then pass through
Spline connects the axis 6 for passing to motor.Drive motor shaft and the plunger pump rotation coaxially connected；Motor drive mode
Under, the arbor that surges does not rotate, and clutch cap 5 disengages automatically with clutch main body 1.The use of non-spring structure, it is real by mechanical movement
Now engagement and disengagement automatically, compares the freewheel clutch of spring structure, has higher reliability.
Using split structure, clutch main body 1 is arranged in active member hydraulic motor and driven element with clutch cap 5
On motor, two kinds of elements produce respectively, each Self management is pacified without separately installed combination with the installation of two kinds of elements automatically
It is attached to position.Easy disassembly is used and is managed.
Split type no spring freewheel clutch according to the present invention, is mainly used in new generation's carrier rocket hydraulic servo
System is transmission/control element of Hydrauservo System, has the functional characteristics of " one way engagement/transmission, reversed to disengage ", with
Adapt to the autonomous switching of servo mechanism day/ground drive mode.
