Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
See Fig. 1, the invention provides a kind of spring clutch, described spring clutch comprises wheel hub 1, clutch cap 6, fan-shaped flywheel 2, directional post 3, Flexible Connector 4 and fan-shaped friction plate 5; And the number of described fan-shaped flywheel 2, described directional post 3, Flexible Connector 4 and described fan-shaped friction plate 5 is 3; Described wheel hub 1 is arranged in described clutch cap 6 coaxially; The peripheral part that 3 described directional posts 3 are circumferentially connected to described wheel hub 1 at each interval extends radially outward respectively; 3 described fan-shaped flywheels 2 and 3 described directional post 3 one_to_one corresponding, be provided with the radial guide groove coordinated with described directional post 3 in described fan-shaped flywheel 2, fan-shaped flywheel 2 described in each to be set on corresponding described directional post 3 by described radial guide groove and can to move radially; 3 described fan-shaped friction plates 5 and 3 fan-shaped flywheel 2 one_to_one corresponding, described fan-shaped friction plate 5 is arranged between described fan-shaped flywheel 2 and described clutch cap 6, fan-shaped friction plate 5 described in each is combined as a whole with corresponding described fan-shaped flywheel 2 respectively, is all connected by described Flexible Connector 4 elasticity between two described fan-shaped friction plates 5 of arbitrary neighborhood.
When wheel hub 1 rotates, be arranged on the effect outwards movement of the fan-shaped flywheel 2 on wheel hub 1 peripheral part due to centrifugal force.When wheel hub 1 rotational velocity is more and more faster, centrifugal force continues to increase, and makes fan-shaped flywheel 2 be subjected to displacement peripheral part away from wheel hub 1 further.Now, be arranged on fan-shaped friction plate 5 on fan-shaped flywheel 2 peripheral part simultaneously near clutch cap 6 inwall until the two contact friction, reach the object of combination.After wheel hub 1 rotational speed declines, centrifugal force weakens, and fan-shaped flywheel 2 sets back, and the combination between fan-shaped friction plate 5 and clutch cap 6 separately.In the movement process of whole fan-shaped flywheel 2, because the mating reaction of directional post 3 and radial guide groove makes the movement of fan-shaped flywheel 2 be in fixing direction always, when avoiding High Rotation Speed, fan-shaped flywheel 2 misplaces.The Flexible Connector 4 connected between fan-shaped friction plate 5 can make whole spring clutch obtain better stability, makes the movement of fan-shaped flywheel 2 and replys better effects if.
Under the effect of the centrifugal force formed in the rotation of wheel hub 1 to make described fan-shaped friction plate 5 and described fan-shaped flywheel 2 away from the inwall near described clutch cap 6 so that fan-shaped friction plate 5 and inwall carry out fricting movement.In whole process, rotational resistance should be reduced as far as possible, make the internals motion in described clutch cap 6 flexible, reduce and rotate energy consumption, improve rotational efficienty, preferably, the described fan-shaped friction plate 5 of integrative-structure and the radial overall length of described fan-shaped flywheel 2 are less than the radial spacing between the outer circumferential face of described wheel hub 1 and the inner peripheral surface of described clutch cap 6.
