Abstract

The utility model discloses a clutch active friction plate for a motorcycle clutch, which comprises a circular ring shaped plate body, at least three locating projections are arranged on a radial outer ring of the plate body, an arc-shaped gap is arranged at the middle portion of the outer edge of the locating projection, a plurality of oil grooves which communicate an inner ring with the outer ring of the plate body along the radial direction are arranged on the front face of the plate body, an oil groove which communicates the arc-shaped gap and the inner ring of the plate body is also arranged on the front face of the plate body, and the back face of the plate body is smooth. The clutch active friction plate for a motorcycle clutch is fine in lubricating and heat dissipating effect, and fast and complete in separation without noise, is wear resistant, and is not easy to skid without sudden rush.

Description

The clutch active friction plate

Technical field

The utility model relates to a kind of motorcycle accessories, especially a kind of clutch active friction plate that is used on the clutch of motorcycle.

Background technique

At present a main Quality of motorcycle is to send out to dash and skid, and cause that a main cause of send out dashing and skidding is that self of friction pair is bonding in the clutch and causes motorcycle to send out to dash, simultaneously because the friction plate self structure causes the friction pair oil storage not enough, quicken the excessive wear of friction plate, and cause skidding of clutch, friction pair comprises active friction plate and from movable friction plate, is to be constituted a cover friction and be used in combination from movable friction plate is stacked between mutually by five active friction plates and five.Existing active friction plate is made ring-like unilateral by materials such as lamination coating or bakelites, extend 8 galleyproof type strong points ring-like around unilateral, so that active friction plate is fixed on the clutch, in order to dispel the heat, clean the frictional loss legacy that produces in the friction process, the pros and cons rubbing surface has many oil seepage slots, thereby prevents that legacy from causing active friction plate in producing the gap between the movable friction plate, skids it.Because active friction plate is two-sided all is rubbing surface, so can not smoothly separate fast when separating, causes the moment of clutch separation also can send knock.

The model utility content

The utility model purpose provides a kind of lubricated good heat dissipation effect, wear-resistant, the clutch active friction plate that separates rapidly thoroughly, do not have when separating sound.

For solving the problems of the technologies described above, clutch active friction plate of the present utility model comprises the lamellar body of toroidal, on the radially outer ring of lamellar body, be provided with and be no less than three locating bumps, the middle part, outer of locating bump is provided with arc notch, on the front of lamellar body, be provided with many oil grooves that radially move towards to be communicated with lamellar body inner ring and outer ring, also be provided with the oil groove that is communicated with arc notch and lamellar body inner ring on the lamellar body front, the back side of lamellar body is even surface.

The number of described locating bump is eight, and they are evenly distributed on the radially outer ring of lamellar body.

After the utility model adopts said structure, by have the locating bump of arc notch in the external circle setting of circular ring plate, and be provided with the oil groove that is communicated with arc notch and lamellar body inner ring in the lamellar body front, the back side of lamellar body is even surface, the lubricant oil that engine spindle is thrown away accumulates in the arc notch place like this, be easy to penetrate into the oil groove at arc notch place, flow into rapidly through oil groove, play lubricated, effects such as cooling, two active friction plates can be combined by even surface, and then with use from the alternate stack of movable friction plate, play buffer function when separating like this, solve the knock that moment sends when separating.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the utility model front schematic view;

Fig. 2 is the utility model schematic rear view;

Fig. 3 is the utility model and the use schematic representation that superposes from movable friction plate.

Among the figure: 1 lamellar body, 2 locating bumps, 21 arc notch, 3,4 oil grooves, 5 from movable friction plate.

Embodiment

Fig. 1, shown in 2 and 3, clutch active friction plate of the present utility model comprises the lamellar body 1 of toroidal, uniformly extension has eight locating bumps 2 on the radially outer ring of lamellar body 1, middle part, outer at locating bump 2 is provided with arc notch 21, on the front of lamellar body 1, be provided with many oil grooves 3 that radially move towards to be communicated with lamellar body inner ring and outer ring, on lamellar body 1 front, also be provided with the oil groove 4 that is communicated with arc notch 21 and lamellar body 1 inner ring, the back side of lamellar body 1 is even surface, per two active friction plates combine by even surface and are one group and are superimposed again with from movable friction plate 5, five groups active friction plate with four from movable friction plate 5 alternate stacks, the outside at them is installed on the clutch by two driven platens, when separating like this, play buffer function, the knock that sends during solution moment separation, during clutch work, external force puts on two outsides of driven disc, make active friction plate and clamp mutually from movable friction plate 5, realize that active friction plate drives from movable friction plate 5 rotations, and then outputting power, noise was low when the utility model used on clutch and to have clutch with the conventional clutch ratio, be difficult for skidding, do not send out and dash, thorough rapidly during separation, not having any catching phenomenon takes place, and lubricated good heat dissipation effect, active friction plate are difficult for burning.

Claims

1, a kind of clutch active friction plate comprises the lamellar body (1) of toroidal, it is characterized in that: on the radially outer ring of lamellar body (1), be provided with and be no less than three locating bumps (2), the middle part, outer of locating bump (2) is provided with arc notch (21), on the front of lamellar body (1), be provided with many oil grooves (3) that radially move towards to be communicated with lamellar body inner ring and outer ring, also be provided with the oil groove (4) that is communicated with arc notch (21) and lamellar body (1) inner ring on lamellar body (1) front, the back side of lamellar body (1) is even surface.

2, clutch active friction plate according to claim 1 is characterized in that: the number of described locating bump (2) is eight, and they are evenly distributed on the radially outer ring of lamellar body (1).
