Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Embodiment 1：As shown in figure 1, a kind of centrifugal clutch, including inner ring 1 and the concentric outer ring 2 of the inner ring 1,
Outer ring 2 is used for external work mechanism, and clutch chamber 3 is provided between the inner ring 1 and the outer ring 2, and clutch chamber 3 is in annulus
Shape, the inner side of the inner ring 1 are provided with the phantom ring 4 of annular shape, and the phantom ring 4 is interference fit with inner ring 2, and inner ring 2 is installed
On bearing, the lateral surface of the phantom ring 4 is provided with convex body 5 corresponding to the position of each clutch chamber 3, it is characterised in that described
The position that each convex body 5 is corresponded on outer ring 2 is provided with the first sliding groove 21, and the outer ring 2 is internally provided with and corresponded to first
The second sliding groove 22 that sliding groove 21 connects, first is respectively arranged with first sliding groove 21 and second sliding groove 22
The sliding bar 24 of sliding bar 23 and second, the bottom of the sliding bar 24 of the first sliding bar 23 and second is respectively by spring and described
First sliding groove 21 is connected with the bottom land of second sliding groove 22, it is preferred that the first sliding groove 21 and second sliding groove
Hydraulic oil is full of in 22, ensures the stability slided, the other end of second sliding bar 24 is provided with the first magnet piece 25, institute
State and be provided with and correspond to the second magnet piece 26 that the first magnet piece 25 repels each other on outer ring 2 so that outer ring 2 rotates, the convex body
5 by with the phase separation of the first sliding bar 23 so that the first magnet piece 25 is close to second magnet piece 26, specifically, described
Force inclined-plane 51 is provided with convex body 5, being provided with first sliding bar 23 has and the force phase separation of inclined-plane 51
The skewback 232 on stress inclined-plane 231.
In the present embodiment, when inner ring 1 rotates, phantom ring 4 rotates therewith, and the force inclined-plane 51 on phantom ring 4 is right
Stress inclined-plane 231 applies pressure, promotes the first sliding bar 23 to be put in the first sliding bar 23, simultaneously so that the second sliding bar 24
The second sliding bar 24 is stretched out, the first magnet piece 25 is close to the second magnet piece 26, repulsion enhancing, finally outer ring 2 is rotated, whole
Individual process, realized in outer ring 2 before rotating, the first magnet piece 25 is in discontiguous state all the time to the second magnet piece 26, and this is just
It ensure that less noise yield and heat.
Preferably, first sliding groove 21 is in 40 ° -60 ° each other with second sliding groove 22.
Preferably, the magnetic pole of all first magnet pieces 25 is set by the path that circumferentially rotates of the outer ring 2, also
It is to say, the magnetic force that the first magnet piece 25 is applied to the second magnet piece 26 prolongs circumferential direction substantially, this setting, at utmost improves magnetic
Force efficiency, the second sliding bar 24 and outreach of the first magnet piece 25 can suitably reduce thereon, that is to say, that can suitably reduce
The rotating speed of inner ring 1 ensures less outreach, and the less rotating speed of inner ring 1 can suitably reduce the generation of heat and the production of noise
It is raw, it is better obvious especially under this internal use environment complicated, air circulation is bad of clutch.
Preferably, it is provided with corresponding spacing ring on the cell wall of first sliding groove 21 and second sliding groove 22.
Embodiment 2：In order that convex body 5 preferably promotes the first sliding bar 23, as shown in Fig. 2 each skewback 232
The arcuate extensions 233 for prolonging the axial direction of inner ring 1 extension are provided with end face, the phantom ring 4 is provided with and corresponding institute
Multiple centrifugal-blocks 6 of the arcwall face phase separation of arcuate extensions 233 are stated, one end of the centrifugal-block 6 is hinged on the phantom ring 4
On, the centrifugal-block 6 is circular arc, and an annulus is formed when all centrifugal-blocks 6 are to contract.
This is set so that centrifugal-block 6 is under certain rotating speed of inner ring 1, its centrifugal action to arcuate extensions 233, should
The thrust of centrifugal force and convex body 5 promotes the first sliding bar 23 jointly, and the present embodiment can be reduced suitably relative to embodiment 1
The rotating speed of the rotating speed of inner ring 1, the same rotation for completing outer ring 2, so that in this internal complicated, air circulation of clutch not
Under good use environment, the less rotating speed of inner ring 1 can suitably reduce the generation of heat and the generation of noise.Meanwhile arc prolongs
The arcwall face of extending portion 233 keeps linear contact lay with centrifugal-block 6, equally can suitably reduce the generation of heat and the generation of noise.
Remaining is the same as embodiment 1.
Embodiment 3：The force inclined-plane 51 and the stress inclined-plane 231 are the magnetic face repelled each other.This is set, and can reduce
The generation of noise and heat during the first sliding bar 23 of promotion of convex body 5.
Remaining is the same as embodiment 2.
