Embodiment
Embodiment 1, by Fig. 1, Fig. 2 and Fig. 5 are as can be known, the present invention is made up of the right side half friction disk 8 that left half friction disk 3 and secure fit on the activity cooperation suit driven shaft 1 are sleeved on the driving shaft 10, a left side half friction disk 3 is provided with clutch and dials circle 2, it is a left side half friction disk bulge loop 4 and 1 left side half friction disk groove 5 of center line that a left side half friction disk 3 is provided with 2 the shaft axis with a left side half friction disk 3, it is center line and the right side half friction disk groove 6 and right half friction disk annular convex ring 7 that match with a left side half friction disk bulge loop 4 and left half friction disk annular groove 5 that right half friction disk 8 is provided with the corresponding shaft axis with the right side half friction disk 8 of left half friction disk, a left side half friction disk bulge loop 4, a left side half friction disk annular groove 5, right half friction disk groove 6 and right half friction disk annular convex ring 7 are tapering groove or the tapering bulge loop of band taper angle Q, and taper angle Q spends less than 45 greater than 0 degree.The shape specification with the right side half friction disk groove 6 and right half friction disk annular convex ring 7 is identical respectively with left half friction disk annular groove 5 for a left side half friction disk bulge loop 4, the bulge loop both side surface of the bulge loop of half friction disk or right half friction disk installs the bigger wearing piece of wear-resisting friction factor 11 on a left side, the inner of wearing piece 11 and bottom portion of groove keep certain interval, go deep in the groove so that bulge loop contacts with wearing piece all the time so that bulge loop can be stretched after wearing piece is worn a part again.
A left side half friction disk adopts splined, both can closely cooperate between wheel Hubs inwall and the driven shaft and also can keep Spielpassung, can make its integrity better because of both closely cooperating, and Spielpassung can compensate the various displacements between the diaxon, can cooperate better when making it to move.
The central authorities of half friction disk or right half friction disk establish cavity on a left side, establish boss 12 at the corresponding with it right side half friction disk or the central authorities of left half friction disk, the specification of the central cavity of left or right half friction disk both can be identical with the central boss of right or left half friction disk keeps in touch making it, to increase transmission torsion.Also can make central cavity make it not contact friction, thereby can avoid passing to driving shaft and driven shaft in frictional heat near driving shaft and the generation of driven shaft place greater than central boss 12.
Because of having changed the transmission principle of clutch, according to mechanical analysis, can make clutch do forr a short time, left and right half friction disk can use low-cost grey cast iron to make, thereby saves manufacture cost.
By accompanying drawing as can be known, the present invention must be by not making left and right sides friction disk separate fully like that when cut-off clutch shown in the accompanying drawing, need only mobile small distance can disengage and realize clutch separation.
Embodiment 2, by Fig. 3-5 as can be known, it is a left side half friction disk bulge loop 4 and 2 left side half friction disk grooves 5 of center line that a left side half friction disk 3 is provided with 3 the shaft axis with a left side half friction disk 3, it is center line and 2 or 3 right sides, half friction disk groove 6 and 2 right side half friction disk annular convex rings 7 that match with a left side half friction disk bulge loop 4 and left half friction disk annular groove 5 that right half friction disk 8 is provided with the corresponding shaft axis with the right side half friction disk 8 of left half friction disk, and the height of central boss can be less than the degree of depth of central cavity.All the other together
Embodiment 1.
Embodiment 3, and a left side half friction disk among embodiment 1 and the embodiment 2 and the mode of structure of right half friction disk surface of contact can exchange, i.e. the interchangeable setting of the structural type of corresponding central cavity, central boss, groove and boss.And more groove and bulge loop can be set as required.All the other are with embodiment 1 and embodiment 2.
In the time of Q=2.5 °, Fn=Fa/sinQ=Fa/sin2.5 °=Fa/0.0436=22.94Fa.Therefore the frictional force F that produces of each rubbing surface is 22.94 times of the frictional force that produces of planar friction dish.
In the time of Q=3.5 °, Fn=Fa/sinQ=Fa/sin3.5 °=Fa/0.061=16.39Fa.Therefore the frictional force F that produces of each rubbing surface is 16.39 times of the frictional force that produces of planar friction dish.
In the time of Q=5 °, Fn=Fa/sinQ=Fa/sin5 °=Fa/0.087=11.494Fa.Therefore the frictional force F that produces of each rubbing surface is 11.49 times of the frictional force that produces of planar friction dish.
In the time of Q=7 °, Fn=Fa/sinQ=Fa/sin7 °=Fa/0.12=8.33Fa.Therefore the frictional force F that produces of each rubbing surface is 8.33 times of the frictional force that produces of planar friction dish.
