Control friction plate 321 and the contact of clutch disk 322 separates, and the clutch effect of clutch 3 is realized with this.Friction plate 321
Contact area between the two can be promoted, is mentioned in the two contact with cross-superimposed set-up mode as clutch disk 322
The frictional force for rising contact surface, to the high-efficient of power transmitting.
Under the engagement state of clutch 3, abutted against between friction plate 321 and clutch disk 322, in the present embodiment
In, it is that spline housing 31 is mobile to power intake 11, band movable friction plate 321 resists clutch disk 322, at this time on transmission shaft 1
Kinetic energy can pass to gear 2 by clutch 3.
Under the discrete state of clutch 3, mutually separated between friction plate 321 and clutch disk 322.In the present embodiment
In, it is that spline housing 31 is mobile to power output end 12, is detached from the abutting with clutch disk 322 with movable friction plate 321, is driven at this time
Kinetic energy on axis 1 is interrupted by clutch 3, and transmission shaft 1 dallies, and gear 2 is inoperative.
Further, clutch 3 further includes the elastic component 34 for connecting spline housing 31, when clutch 3 is disengaged shape
When state, elastic component 34 is applied to a driving force on spline housing 31 under the effect of natural resiliency restoring force always, and driving force can make
Spline housing 31 is moved with respect to clutch box 32 so that clutch 3 replys engagement state.In the present embodiment, elastic component 34 is one
Spring, the setting of elastic component 34 are to restore engagement state by discrete state for spline housing 31 to provide restoring force, and elastic component 34 is two
Down trodden state is remained in a state, 34 pressure of elastic component is greater than clutch when clutch 3 is in discrete state
34 pressure of elastic component when mechanism 3 is in engagement state, the pressure on elastic component 34 can make friction plate 321 in joint shape
It is bonded when state with clutch disk 322 closer.
Further, elastic component 34 is set on transmission shaft 1, and one end resists clutch box 32, and the other end resists
Shoulder in spline housing 31.Elastic component 34 is compressed between spline housing 31 and clutch box 32 in the present embodiment, elastic component 34
On remain the stress of compression, this stress can be resetted to spline housing 31 to be provided power and makes friction plate 321
It is bonded in engagement state with clutch disk 322 closer.
Further, clutch pack further includes pushing mechanism 4, and pushing mechanism 4 can push spline housing 31 along transmission shaft 1
Axial movement so that clutch 3 by engagement state variation be discrete state.Pushing mechanism 4 is positioned to auxiliary in the present embodiment
Spline housing 31 is helped to realize that the engagement state of clutch 3 is switched to discrete state, pushing mechanism 4 is gone back in other embodiments
It is able to achieve switching of the spline housing 31 from discrete state to engagement state.
Further, pushing mechanism 4 is provided with capacity eccentric bearing 41 close to one end of spline housing 31, and capacity eccentric bearing 41 can be with inclined
