Embodiment

Below in conjunction with accompanying drawing in detail specific embodiment of the utility model is described in detail.

A kind of electronic controled multi-plate wet clutch comprises clutch part and armature component.

Please refer to Fig. 1, clutch part comprises bent axle 1, the driving gear 2 with bent axle 1 suit, clutch outer member 19, is positioned at the end cap 18 in shell 19 outsides, be provided with clutch with driving disc 25, driving disc 25 that shell 19 cooperates flies piece 20 and clutch spring 3, driving gear overcoat 24, becomes the driven hub 23 of screw pair structure and active friction plate 22 with driving gear overcoat 24 external tooths and from movable friction plate 21.

Described armature component comprises the rotating disk 4 that is fixed on the driving disc 25, be sleeved on the armature seat 5 outside the rotating disk 4, be arranged at the coil rack 6 in the armature seat 5, be fixed in the armature coil 7 on the coil rack 6, be arranged at the pole wheel 8 in the rotating disk 4, be fixed in the ball screw 16 at pole wheel 8 centers, ball screw 16 is provided with the bearing 17 that is positioned at end cap 18 centers near an end of clutch part, the other end of ball screw 16 is provided with feed screw nut 16A that is fixed together with armature seat 5 and the position-limited shaft 15 that is connected with ball screw 16, with the limited wheel 13 of position-limited shaft 15 by spline fitted, be positioned at the acceleration cable 12 of limited wheel 13 grooves and the banking stop 14 that cooperates with limited wheel 13.

Wherein feed screw nut 16A and armature seat 5 are fixed together by locating stud 9.Described limited wheel 13 is fixed together by set screw 11 with position-limited shaft 15, and the centre is provided with packing ring 10.

Please refer to Fig. 3 and Fig. 4, described banking stop 14 is coated at limited wheel 13, and limited wheel 13 is provided with restraining groove 13A, and described banking stop 14 is a C type structure, and banking stop 14 openings are provided with the interior convex portion 14A that is close together, and interior convex portion 14A cooperates with restraining groove 13A.Limited wheel 13 rotation angles thereby be subjected to the restriction of the interior convex portion of banking stop 14 have buffer function when therefore colliding.

Shown in Figure 1, the utility model electronic controled multi-plate wet clutch is complete lubricated wet clutch, adopts active friction plate 22 and driven 21 to compress the working principle that produces the frictional force transmitting torque.When bent axle 1 rotation reached certain rotating speed, clutch flies piece 20 because the pressure that centrifugal action produces reaches the precompression that overcomes clutch spring 3, makes active friction plate 22 and fits mutually from movable friction plate 21, produces frictional force, makes clutch be in bonding state.

When the clutch that is in bonding state acts on pressure on the end cap 18 when reaching the elastic force that overcomes clutch spring 3, clutch outer member 19 produces and moves axially, and breaks away from the restriction that clutch flies piece from movable friction plate, begins to reset.Be separated from each other from movable friction plate 21 and active friction plate 22 this moment, and clutch is in separated state again.

When the rotating speed of bent axle 1 hangs down, clutch is in separated state, at this moment, if driving gear 2 is reversed drag, driving gear overcoat 24 produces relative rotation with driven hub 23, and the internal tooth of the external tooth of driving gear overcoat 24 and driven hub 23 is the screw pair structure, so driven hub 23 moves axially, promotion is fitted mutually from movable friction plate 21 and active friction plate 22, produces friction, and makes clutch be in bonding state again.

Please in the lump with reference to figure 1 and Fig. 2, in use, during coil 7 energisings, armature seat 5, rotating disk 4, pole wheel 8 form a closed magnetic circuit, in magnetic field, because the magnetic line of force is closeer in the tooth utmost point 81 distributions of pole wheel 8, and it is rarer to distribute between cog 82, rotating disk 4 is installed on the driving disc 25, together rotate with driving disc 25, when clutch rotated, the rotating disk 4 and the tooth utmost point 81 were done relative movement, among the magnetic flux of rotating disk 4 each points is in and constantly repeats to change.Use the law of electromagnetic induction, induced potential produces eddy current on the rotating disk 4, and eddy current and tooth pole field interact, and the generation torque is rotated pole wheel 8 and rotating disk 4 works in the same way, drive ball screw 16 and rotate, and generation moves axially the formation end thrust.When end thrust reached the elastic force that can overcome clutch spring 3, clutch outer member 19 produced and moves axially, and is separated from each other from movable friction plate 21, active friction plate 22, makes clutch be in separated state.When electromagnetic coil 7 outages, the interaction torque of eddy current and magnetic pole and magnetic field disappears, and clutch disengaging spring elastic force promotes clutch outer member 19, end cap 18 produces and moves axially, thereby causes pole wheel 8 to reset.

When pole wheel 8 rotates, produce active force in the spacing breach of ball screw 16 limiting stoppers on position-limited shaft 15, promote position-limited shaft 15 and rotate, limited wheel 13 rotates simultaneously.When limited wheel 13 rotated, acceleration cable 12 produced displacement, and acceleration cable 12 the other ends and Carburetor link, the control carburetor throttle opening; Cut-off clutch has reduced the Carburetor accelerator open degree simultaneously, has limited engine speed, is beneficial to transforming gear.
