Description of the Invention: [Technical Field] The present invention relates to a clutch structure, and more particularly to a clutch structure in which a 1 engine shifts smoothly. ; σ < [Prior Art] For general vehicles, whether it is a car or a locomotive, the shifting mechanism of the disc engine is equipped with a clutch, which is more commonly used as a centrifugal clutch, which can provide an engine for rebranding. At this time, the shifting action of the shifting mechanism is achieved by the separation. "...Without today's sand shovel, its engine is mainly connected with a --segment shifting mechanism and a forward-reverse gear mechanism, so that the aforementioned ATV can move forward, and if necessary, retreat . However, when the sand truck is at idle speed, during the conversion from forward to reverse, or 15 to reverse to forward, the clutch plate on the clutch drive disc must be disengaged from the clutch casing, causing the clutch casing to stop rotating and promote: The rotating shaft set on the clutch casing stops rotating, so that the gear shifting action can be performed. The gear on the rotating shaft may not be completely correct on the corresponding gear of the groove to be changed, that is, the gear on the rotating shaft has It is possible that the 20 concave portions thereof also correspond to the aforementioned corresponding toothed concave portions>, so that the gears cannot be meshed very smoothly to achieve the purpose of shifting, which causes the ATV to be unsmooth when used, and is likely to cause abnormal sounds. The occurrence of this seriously affects the value of goods. 1290992 - SUMMARY OF THE INVENTION The clutch structure of the present invention includes a rotating shaft, a clutch housing, an alpha and a driving disc 'wherein the clutch housing includes a disc body, the disc body including a central hole, the central hole securing Provided on the rotating shaft, and the outer edge of the disc body 5 and extending axially has a ring flange, and the ring flange includes an inner annular surface. In addition, the driving plate includes a driving plate, a plurality of clutch plates, and a nut, wherein the plurality of clutch plates are respectively pivoted on the driving plate and are outwardly supported by centrifugal force and abut against the clutch. The inner side of the jacket is 10 toroids, and the nut is screwed onto the drive plate. The present invention is characterized in that the nut is disposed at least with an opening corresponding to the disc body of the clutch sleeve, and the at least one opening receives a friction device, and the friction device includes a friction column. It is outwardly threaded out of at least one opening of the nut and correspondingly abuts against the body of the clutch sleeve. φ Therefore, when the engine is idling, the clutch casing can still be rotated by the frictional force of the friction column of the friction ring, thereby driving the shaft protection: thus facilitating the gear meshing action during the shifting, and thereby reducing the abnormal sound With the generation of vibration. 〃 2〇 In addition, the above structure is provided with a friction device directly on the nut of the driving plate, so that the entire part configuration can be more simplified, and the manufacturing and grouping of the parts can be greatly improved, and at the same time, if damage occurs. In this case, only the nut can be replaced during maintenance, and the performance is better for the convenience of maintenance. The at least one opening of the above-mentioned nut may be provided with an upper opening and a lower opening, wherein the upper opening corresponds to the disc body of the clutch sleeve, and the friction column is received by the lower opening into the at least one opening, And outwardly out of the upper opening, and corresponding to the disk body against the clutch jacket. Further, the above-mentioned friction device may include a bottom plate which is coverable on the lower opening. In addition, the friction device may include an elastic member that is received in at least one opening of the nut and abuts between the friction column and the bottom plate, and the elastic member provides a resilient pre-force to urge the friction column toward The outer disk is pierced out of the upper opening 10 and corresponds to the disk body of the clutch outer casing. The number of at least one opening of the nut may be three and is equally angularly disposed on the nut. Of course, the number of openings is not limited to three, and may be one, two, four, five, and the like.

A cross-sectional view showing the above-described clutch structure 7 includes a rotating shaft 1, a clutch housing 2, and a driving plate 3. 7 1290992 The clutch casing 2 of the drawings comprises a disc body 21, and the disc body 21 comprises a central hole 211, which is fixed to the above-mentioned rotating shaft 1 at the same time, the disc body 21 The outer rim extends axially with a ring flange, and the ring flange 212 includes an inner annular surface 213. 5 _ . In addition, the driving plate 3 in the drawing includes a driving plate 31, a plurality of clutch plates 32, and a nut 33, wherein the plurality of clutch plates 32 are three in the number in the embodiment, and the system is respectively pivoted It is disposed on the driving plate 3 and is outwardly supported by the centrifugal force and abuts against the inner ring 213 of the clutch casing 2, and the nut 33 is screwed onto the driving plate 31. In addition, the nut 33 in the drawing is provided with three opening holes 331 which are disposed at equal angles on the nut 33, and each of the openings 331 includes an upper opening 332 and a lower opening 333, wherein The upper opening 332 corresponds to the disk body 21 of the clutch housing 2. Each of the openings 331 is provided with a friction device 4, so that there are a total of three 15 friction devices 4, each of which includes a friction column 41, a bottom plate 42, and an elastic member 43, wherein the friction column 41 The utility model is made of a polymer material, which is accommodated in the opening 331 by the opening 333 of the opening 331 and extends outwardly out of the upper opening 332 and correspondingly to the disc of the clutch outer casing 2 Body 21. 20, the bottom plate 42 of the friction device 4 is respectively disposed on the opening 333 below the opening 33 1 and the elastic members 43 of the friction device 4 are respectively received in the opening 331 and abut against the friction column 41 and the bottom plate 42 In the present embodiment, the elastic member 43 is a spring which can provide an elastic pre-force to urge the friction column 41 to 8 1290992.
外穿出上開口 332之外、並對應頂抵於離合器外套2之圓盤 體21。 因此’當引擎於怠速時，摩擦裝置4之摩擦柱41可利用 彈性元件43之彈性預力而對應頂抵於離合器外套2之圓盤 體21，亦即可使離合器外套2因為摩擦裝置4之摩擦柱“之 摩擦力而轉動，進而驅動轉軸丨保持轉動，如此可利於換檔 時之齒輪嚙合動作，並可藉以減少異音與振動之產生。The disk body 21 is disposed outside the upper opening 332 and correspondingly against the clutch casing 2.
