Abstract
An automatic clutch comprises a driving gear with housing, a shoe block combination and an isolator. The utility model is characterized in that: The isolator includes an isolator cover plate, rollers and an underpan spline support; involute slots are provided on inside wall of the isolator cover plate and the rollers are inside the involute slots; the isolator cover plate is sleeved onto the driving gear shaft sleeve; the isolator cover plate and the underpan spline seat are mounted with the shoe block retainer on the shoe block combination. The utility model has the advantages of simple structure and convenient assembling, with which simple assembling and convenient maintenance effects can be fulfilled, so that production cost and maintenance cost can be lowered considerably and skid phenomenon can be eliminated.
Description
(1), affiliated technical field
The utility model relates to a kind of clutch, particularly a kind of automatic clutch that is used on the motorcycle engine.
(2), technical background
At present, the automatic clutch of motorcycle engine generally is to be formed with clutch hoof piece combine and assemble by the clutch housing combination.Wherein the separating mechanism of clutch is the one group of one-way element that is contained in the clutch housing combination.This one-way element structure adopts the mode of welding to be welded on the outer cover, and the structure of this one-way element is also comparatively complicated, can be divided into one-way element body, one-way element spring, one-way element roller, one-way element inner spline housing and back-up ring; This hoof piece combination mostly is with one-way element inner spline housing and engine crankshaft carries out spline fitted, the spline housing of hoof piece and hoof piece retainer are for being welded, so just make the complex structure of its clutch, manufacture cost is very high, and it is very inconvenient in assembling, the expense of maintenance during startup, still skidding can occur than higher.
(3), summary of the invention
It is low and assemble automatic clutch more easily that the purpose of this utility model just provides a kind of simple in structure, processing and maintenance cost, and it can avoid the generation of skidding.
The purpose of this utility model is to realize by such technological scheme, it includes driving gear, the combination of hoof piece and the one-way element of band outer cover, it is characterized in that: one-way element includes one-way element cover plate, roller and chassis spline fitting, the inwall of one-way element cover plate is provided with gradually fluting, gradually be placed with roller in the fluting, the one-way element cover plate is placed on the axle sleeve of driving gear, and the hoof piece retainer in one-way element cover plate, chassis spline fitting and the combination of hoof piece is fixed together.
The utility model is work like this: when clockwise rotating under the startup of driving gear at motor of band outer cover, roller in the one-way element is gradually rolling along gradually narrow direction in the fluting, thereby its one-way element cover plate and driving gear axle sleeve are adjacent to each other by roller, thereby the rotation of the one-way element cover plate that has been adjacent to by the driving gear of band outer cover drives the combination of hoof piece and rotates, and the clutch of this moment is in bonding state; When the rotation of hoof piece combination arrives certain speed, the hoof piece of hoof piece combination outwards opens, the outer cover that makes up with outer cover reaches and fits tightly, guaranteed the generation of non-slip phenomenon, realize rotating together reliably of combination of hoof piece and outer cover combination, at this moment, the combination of hoof piece is just given motorcycle engine transmission of power, make the engine start of motorcycle, the motorcycle engine high speed operation makes the driving gear of being with outer cover be in respect to the combination of hoof piece and rotates counterclockwise, at this moment, roller in the one-way element is under the frictional force action of centrifugal force and driving gear axle sleeve, direction along the broad of gradually slotting is rolled, and the one-way element and the driving gear of band outer cover is separated, at this moment, the power of hoof piece combination just can not pass to driving gear, and clutch just is in separated state automatically.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to assembly, use it can play assembling effect simple, easy to maintenance, obviously reduced cost of production and maintenance cost, avoided the generation of skidding.

Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a hoof piece composite structure schematic representation of the present utility model;
Fig. 3 is a B-B sectional view among Fig. 2;
Fig. 4 is an one-way element structural representation of the present utility model;
Fig. 5 is an outer cover composite structure schematic representation of the present utility model;
Fig. 6 is the A-A sectional view of Fig. 5.
Among the figure: 1. hoof piece retainer; 2. be with the driving gear of outer cover; 3. one-way element; 4. one-way element cover plate; 5. chassis spline fitting; 6. roller; 7. one-way element spring; 8. gradually slot; 9. driving gear axle sleeve;
(5), embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes driving gear 2, the combination of hoof piece and the one-way element 3 of band outer cover, and as can be known in conjunction with Fig. 2,3,4,5,6, it is characterized in that: one-way element 3 includes one-way element cover plate 4, roller 6 and chassis spline fitting, the inwall of one-way element cover plate 4 is provided with gradually slots 8, gradually slotting is placed with roller 6 in 8, and one-way element cover plate 1 is placed on the driving gear axle sleeve 9, and the hoof piece retainer 1 in one-way element cover plate 4, chassis spline fitting 5 and the combination of hoof piece is fixed together.
The utility model is work like this: when clockwise rotating under the startup of driving gear 2 at motor of band outer cover, roller 6 in the one-way element 3 rolls along gradually narrow direction in 8 gradually slotting, thereby its one-way element cover plate 4 is adjacent to each other by roller 6 with driving gear axle sleeve 9, thereby the rotation of the one-way element cover plate that has been adjacent to 4 by the driving gear 2 of band outer cover drives the combination of hoof piece and rotates, and the clutch of this moment is in bonding state; When the rotation of hoof piece combination arrives certain speed, the hoof piece of hoof piece combination outwards opens, the outer cover that makes up with outer cover reaches and fits tightly, guaranteed the generation of non-slip phenomenon, realize rotating together reliably of combination of hoof piece and outer cover combination, at this moment, the combination of hoof piece is just given motorcycle engine transmission of power, make the engine start of motorcycle, the motorcycle engine high speed operation makes the driving gear 2 of being with outer cover be in respect to the combination of hoof piece and rotates counterclockwise, at this moment, roller 6 in the one-way element 3 is under the frictional force action of centrifugal force and driving gear axle sleeve 9, direction along 8 broads of gradually slotting is rolled, and the one-way element 3 and the driving gear 2 of band outer cover is separated, at this moment, the power of hoof piece combination just can not pass to the driving gear 2 of band outer cover, and clutch just is in separated state automatically.
As shown in Figure 4, gradually slot 8 number is three.
As shown in Figure 4, be provided with one-way element spring 7 in 8 gradually slotting, one-way element spring 7 one ends are against gradually slots on 8, and the other end is against on the roller 6.When the driving gear 2 of band outer cover is in when rotating counterclockwise with respect to hoof piece combination, roller 6 in the one-way element 3 is under the frictional force action of centrifugal force and driving gear axle sleeve 9, direction along 8 broads of gradually slotting is rolled, one-way element spring 7 promotes rollers 6 to be made that it is faster, better rolls along direction of 8 broads of gradually slotting, thereby the driving gear 2 that makes one-way element 3 and band outer cover reliably, separate better.
