Description

Clutch device

Technical Field

The utility model relates to a motorcycle engine technical field specifically is a clutch.

Background

The engine of motorcycle is a machine which ignites the fuel mixture in the cylinder to burn and generate heat energy to be changed into mechanical energy, and the power is transmitted to the rear wheel of the motorcycle by a crankshaft through a transmission mechanism to be changed into the driving power of the vehicle. The clutch is used as a structure in the engine and mainly used for transmitting or cutting off the power of the engine to realize the forward movement and gear shifting of the motorcycle. In addition, when the motorcycle suddenly encounters large impact, the clutch can slip between the driving friction plate and the driven friction plate, and the impact of external force on the engine is relieved to a certain extent, so that a certain protection effect can be generated on the engine.

The friction plate of the clutch of the existing motorcycle engine has two setting modes, one mode is that the active friction plate of the clutch is directly contacted with the aluminum alloy surfaces of the central sleeve and the pressing plate, but the setting can lead the clutch to have the phenomenon that the central disc and the pressing plate are abraded after the clutch is used for a period of time, the replacement frequency of the clutch is increased, aluminum scrap impurities can also cause abrasion to other parts of the engine after the abrasion, and the service life of the whole engine can be influenced; the other mode is that steel inserts are additionally arranged in the surfaces of the central sleeve and the pressure plate, which are in contact with the friction plate, although the structure can solve the problem of abrasion of an aluminum alloy surface, the mode can cause the defects of complex casting process, large heat treatment deformation, large machining difficulty and the like, and the machining cost of the engine is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a clutch to solve the problem that current clutch easily weares and teares.

The utility model provides a basic scheme is: a clutch comprises a pressure plate, a center sleeve and a driving friction plate, wherein the center sleeve is provided with a limiting groove, the pressure plate is provided with a limiting boss matched with the limiting groove, the driving friction plate is sleeved on the center sleeve, and the center sleeve is connected to the pressure plate;

wherein: the central sleeve is provided with a limiting lug matched with the limiting groove, and the central sleeve is provided with a limiting lug matched with the limiting lug.

The basic scheme has the beneficial effects that: compared with the prior art, in this scheme, utilize the setting of spacing piece on the one hand, avoid the direct contact of initiative friction disc and center cover and pressure disk to can reduce the wearing and tearing of other spare parts that arouse because of wearing and tearing produce aluminium bits impurity, and aluminium bits impurity reduces and can also improve the lubricating oil cleanliness, and on the other hand, spacing lug can make things convenient for the installation or the dismantlement of spacing piece on the clutch with the cooperation of spacing draw-in groove, easy operation.

Furthermore, the limiting sheet is a steel sheet. Has the advantages that: in this scheme, adopt the steel sheet that intensity is big as spacing piece, can guarantee the long-term use of spacing piece to the life of clutch has been improved.

Furthermore, the limiting convex blocks are provided in a plurality. Has the advantages that: the arrangement of the plurality of limiting lugs can ensure that relative motion cannot be generated between the limiting plate and the central sleeve as well as between the limiting plate and the pressure plate, so that the abrasion caused by the relative motion between the limiting plate and the central sleeve as well as between the limiting plate and the pressure plate can be reduced, and the service life of the clutch is further prolonged.

Furthermore, four limiting lugs are arranged. Has the advantages that: the four limiting lugs are arranged to ensure that relative motion cannot be generated between the limiting piece and the central sleeve as well as between the limiting piece and the pressure plate, and meanwhile, the production cost of the limiting piece can be reduced.

Furthermore, four spacing lugs are evenly arranged at intervals. Has the advantages that: the spacing lugs arranged at even intervals ensure that the stress of each spacing lug is even, thereby prolonging the service life of the spacing piece.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the friction plate comprises a limiting plate 1, a limiting lug 10, a pressure plate 2, a limiting boss 21, a limiting clamping groove 22, a central sleeve 3, a limiting groove 31 and an active friction plate 4.

The embodiment is substantially as shown in figures 2 to 5: the clutch comprises a pressure plate 2, a center sleeve 3, a driving friction plate 4 and a driven friction plate, wherein a limiting groove 31 is formed in the center sleeve 3, a limiting boss 21 matched with the limiting groove 31 is formed in the pressure plate 2, the driving friction plate 4 is sleeved on the center sleeve 3 and is located between the driven friction plate and the pressure plate 2, and the center sleeve 3 is connected to the pressure plate 2.

Still be provided with spacing piece 1 between initiative friction disc 4 and preforming, as shown in fig. 1, spacing piece 1 still is provided with the spacing lug 10 that matches with spacing groove 31, is provided with the spacing draw-in groove 22 that matches with spacing lug 10 on the spacing boss 21 of pressure disk 2, and in this embodiment, evenly provided with four spacing lugs 10 at the interval on the interior circumference on spacing piece 1, relatively, on pressure disk 2, correspondingly be provided with four spacing draw-in grooves 22 on the even four spacing bosses 21 in interval.

The clutch in this embodiment is applicable to all kinds of engines that have clutch mechanism, utilizes spacing piece 1 to avoid the wearing and tearing that initiative friction disc 4 led to the fact to center sleeve 3 and pressure disk 2, promotes clutch life, improves lubricating oil cleanliness simultaneously, reduces and closes heavy spare part wearing and tearing, increases engine life.
