Abstract
The utility model discloses a throwing block structure of a centrifugal clutch. The throwing block structure comprises a throwing block body, wherein a connecting hole is formed in one end of the throwing block body and a lug boss is formed in the outer side face of the throwing block body, close to the connecting hole. The throwing block structure of the centrifugal clutch is simple; the centrifugal force borne by the throwing block forms a lever structure through the lug boss, and is magnified and transmitted to a friction block, so that the pressure of a friction piece is effectively increased and the friction force between the friction piece and a clutch drum is increased, and therefore the transmission torque of the centrifugal clutch is increased.
Description
Technical field
The utility model relates to centrifugal clutch technical field, relates in particular to a kind of block structure that gets rid of for centrifugal clutch.
Background technique
Rotating speed clutch is normally for the clutch on motorcycle, traditional rotating speed clutch is mainly by clutch drum, brake pad, returning pull-spring and brake pad retainer, described brake pad retainer middle part has the output sleeve with spline, the middle part of clutch drum has the axle sleeve hole corresponding with this output sleeve, during assembling, friction plate retainer is installed in clutch drum, and the axle sleeve hole of one end of axle sleeve from clutch drum passes; One end of brake pad is connected with brake pad retainer edge by rotating shaft, and the other end of brake pad is connected with one end of returning pull-spring, and the other end of returning pull-spring is connected with adjacent brake pad; The inner side surface at described clutch drum edge is rubbing surface, axle sleeve reaches after certain rotating speed, and brake pad overcomes the pulling force of returning pull-spring under the effect of centrifugal force, with the inner side surface laminating at clutch drum edge, thereby produce friction with clutch drum, and drive clutch drum to rotate by frictional force.But because the volume weight of brake pad itself is limited, therefore in the course of the work, the centrifugal force that brake pad produces is less for such rotating speed clutch, thus cause and clutch drum between the frictional force that produces less, and then the moment of torsion that causes rotating speed clutch to transmit is less, cause outputting power not enough.
In order to increase output torque, be mainly at present increase the weight of brake pad or increase moment of torsion by other labyrinths by expanding the volume of clutch, but cause and make trouble so again, bulky, station poor stability, and cost increase, be unfavorable for promoting the use of.For this reason, claimant has designed a kind of friction plate of applicable and centrifugal clutch, but need to design a kind of block structure that gets rid of, and to increase the suffered pressure of friction plate, thereby increases the frictional force between friction plate and clutch drum, and then increases transmitting torque.
Model utility content
For prior art above shortcomings, technical problem to be solved in the utility model is how to increase the output torque that clutch transmits, and a kind of block structure that gets rid of for centrifugal clutch is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is such: a kind of block structure that gets rid of for centrifugal clutch, it is characterized in that: comprise and get rid of block body, described one end of getting rid of block body has an attachment hole, at the outer side surface that gets rid of block body, near connection hole, is provided with a boss.
Further, described boss is curved.
Further, described in get rid of block body and expand and form expansion section away from one end of attachment hole, this expansion section is positioned at the same side of boss curved, makes to get rid of the center of gravity of expansion section of block body near clutch drum.
A kind of friction component of centrifugal clutch, it is characterized in that: comprise above-mentioned block structure and the friction plate of getting rid of, the described block structure that gets rid of is located at friction plate inner side, and get rid of block structure and friction plate and there is overlapped part, and get rid of boss on block structure and be positioned at and get rid of block structure and the overlapping part of friction plate, make to get rid of block structured boss can act on friction plate on.
Compared with prior art, the utlity model has following advantage:
1, simple in structure, getting rid of block structure is formed suffered centrifugal force after lever construction amplifies and is passed to brake pad by boss, thereby can effectively increase the pressure that friction plate is subject to, thereby improve the frictional force between friction plate and clutch drum, and then increase the moment of torsion that centrifugal clutch transmits.
2, by split-type structural, can effectively dwindle the volume of clutch, reduce clutch weight.
3, simple in structure, working stability is reliable.
Accompanying drawing explanation
Fig. 1 is for originally getting rid of block structured structural representation;
Fig. 2 is the structural representation of this friction component;
Fig. 3 is the assembly structure schematic diagram of centrifugal clutch.
In figure: 1-block body got rid of, 2-attachment hole, 3-boss, 4-expansion section, 5-friction plate, 6-clutch drum.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, Fig. 2 and Fig. 3, a kind of block structure that gets rid of for centrifugal clutch, comprise and get rid of block body 1, described one end of getting rid of block body 1 has an attachment hole 2, when assembling, by rotating shaft and coordinating of this attachment hole 2, will get rid of block structure is arranged on retainer, making to get rid of block structure can freely rotate, easy for installation, quick.Near attachment hole 2 places, be provided with a boss 3 getting rid of the outer side surface of block body 1 side of friction plate (during assembling near), get rid of like this block structure when the rotating shaft around matching with attachment hole 2 is rotated, under centrifugal action, expand outwardly, boss 3 by outer side surface passes to power the friction plate 5 matching, thereby the power that friction plate 5 is subject to is larger, and then make the frictional force between friction plate 5 and clutch drum 6 larger, thereby can transmit larger moment of torsion.During concrete enforcement, get rid of block body 1 whole curved, boss 3 is positioned at the outer side surface that gets rid of block body 1.
Described boss 3 is curved; Make to get rid of block body 1 in getting rid of piece rotating shaft rotation process, even transition between boss 3 and friction plate 5, and lasting stressed, thus make the stressed more evenly increase of friction plate 5, and stable.
The described block body 1 that gets rid of expands and forms expansion section 4 away from one end of attachment hole 2, and this expansion section 4 is positioned at the same side (i.e. outside) of boss 3 curved, makes to get rid of the close clutch drum 6 of center of gravity (trying one's best) of the expansion section 4 of block body 1.The free end quality of getting rid of like this piece is larger, and the radius of gyration is also larger, can make to get rid of the power that piece passes to friction plate 5 through projection larger, thereby improve the frictional force between friction plate 5 and clutch drum 6, with transmitting torque better.
Referring to Fig. 2, a kind of friction component of centrifugal clutch, comprise above-mentioned block structure and the friction plate 5 of getting rid of, the described block structure that gets rid of is located at friction plate 5 inner sides, and get rid of block structure and friction plate 5 has overlapped part, and get rid of boss 3 on block structure and be positioned at and get rid of block structure and the overlapping part of friction plate 5, make to get rid of block structured boss 3 and can act on friction plate 5.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
