Abstract
The utility model relates to a clutch assembly with an auxiliary separating structure, which comprises a driving disc combination, a center sleeve, a pressure plate, a pressure spring, a lift slab, driving discs and driven discs, wherein the driving discs and the driven discs are matched to form a plurality of friction pairs. The friction pairs are respectively provided with through holes at the centers of the outer diameter edge teeth of the third driving disc and the fourth driving disc or the driving discs at even bits. Separating springs are arranged in the through holes. Both ends of each separating spring contact two driving disc teeth at both sides. The utility model separates the driving discs from the driven discs through the separating springs on friction plate, which avoids the phenomenon of cold starting of a motorcycle, and the effect is obvious. The utility model has the advantages of simple improved structure and low extra cost of the clutch.
Description
Technical field
The utility model belongs to the clutch for motorcycle technical field, is specifically related to a kind of clutch assembly with auxiliary separation structure.
Background technique
Clutch is being on the motorcycle between bent axle and the speed changer, and its function is to connect and cut off transmission of power to power train, makes the motorcycle can gentle start; Smoothly shifted and avoid the power train overload.Its working method of existing clutch of motorcycle assembly is: when the motorcycle engage a gear, hold with a firm grip the separation handle of solenoidoperated cluthes, under the effect of detaching cam power, the stage clip of compression clutch, because the central sleeve of clutch is an axial restraint, so platen axial motion (general mobile 1.5-2mm).Releasing is to the pressure of rotating plate and driven plate, so that their transmitting torques not are convenient to motorcycle and are realized engage a gear.But, in actual use, owing to be subjected to weather effect, as low season of temperature or in cold place, it is big that the viscosity of machine oil can become, the employed in the market rotating plate overwhelming majority is the rubber-based rotating plate simultaneously, adhesive force is strong, is running into cold day, when engage a gear, although rotating plate and driven plate are not subjected to the effect of stage clip power, they still can stick to one, this moment engage a gear they still can transmitting torque, cause motorcycle in preshoot rapidly in a flash, Here it is, and the problem of dashing is sent out in the normal cold start-up that occurs of motorcycle, brings dangerous factor to use.
Summary of the invention
The problems referred to above at the prior art existence, the purpose of this utility model is to provide a kind of clutch assembly with auxiliary separation structure, by the auxiliary separating mechanism of design on friction plate, help the separation between rotating plate and the driven plate, avoid motorcycle cold start-up to occur and send out the phenomenon of dashing.
The technical solution of the utility model is as follows:
This clutch assembly includes all parts of existing structure: driving disc combination, central sleeve, platen, stage clip, lift slab, rotating plate and driven plate etc., rotating plate cooperate with driven plate forms a plurality of friction pairs.Concern on the immovable basis that at existing structure at the outer diameter side uncinus center of the rotating plate that is in even bit or the 3rd, the 4th rotating plate processing through hole, this through hole can adopt more than two, is evenly distributed in the plural edge teeth respectively.The separation spring is set in the through hole, and the two ends of separating spring contact with two rotating plate teeth of both sides.Behind the screw of tightening the central sleeve combination, stage clip is compressed and produces axial pressure, and under this power effect, rotating plate and driven plate are compacted, and the rotating plate that separates the spring two ends simultaneously also will separate the spring compression when being subjected to the stage clip axial pressure.It is behind the pressure of platen releasing to rotating plate and driven plate that the purpose of separating spring is set, separate spring in being returned to the free state process in, distance support between the rotating plate at separation spring two ends is big, rotating plate that separately adheres to each other and driven plate, master and slave moving plate is disengaged, make corresponding the reducing of friction torque that their produce, reduce the ability that their transmit frictional force, thereby motorcycle is sent out and dashed when avoiding cold start-up.
Such architecture advances is fairly simple, and effect is obvious, and the cost that clutch is increased is also very little.
Description of drawings
Fig. 1 is the clutch assembly structural representation that has 8 groove outer covers of auxiliary separation structure through improved.
Fig. 2 is the structural drawing that is in the rotating plate of even bit among Fig. 1.
Fig. 3 is the structural representation of driven disc built-up section in the clutch assembly of improved 16 groove outer covers with auxiliary separation structure, and wherein Fig. 3 A is a plan view, and Fig. 3 B and Fig. 3 C are respectively A-A and the B-B sectional drawings of Fig. 3 A.
Embodiment
Referring to Fig. 1, this is the clutch assembly of one 8 groove cover structure, and its parts are formed to be had: driving disc combination 1, central sleeve 7, platen 2, stage clip 8, lift slab 9, rotating plate 31,32,33,34,35, driven plate 41,42,43,44, separation spring 5 etc.The rubbing surface of five rotating plates and four driven plates and central sleeve 7, platen 2 is formed ten friction pairs.Between two rotating plates 31 that are in the radix position are with 33,33 and 35, be provided with respectively and separate spring 5 at the outer rim place, separating spring 5 two ends contacts with two rotating plate teeth that are in the radix position, separate spring 5 middle parts and be in the through hole of two marginal tooth centers of symmetry of the rotating plate 32,34 of even bit opening 6 from the centre and pass, the partial structurtes of rotating plate that are in even bit are referring to Fig. 2.
After platen 2 axial motion left, rotating plate moves axially left under the effect that separates spring 5, like this, ten friction pairs have originally just become and have been less than 7 friction pairs, the moment of torsion that can transmit is just less than original 7/10, this friction torque that it is produced can not make motorcycle travel forward, efficiently solves cold start-up and sends out the problem of dashing.
Clutch for 16 groove cover structures, the realization of this structure is referring to Fig. 3 A, Fig. 3 B and Fig. 3 C, because 45 ° of first rotating plate 31 and other 4 rotating plates, 32,33,34,35 wrong shapes, therefore separating spring 5 is installed on respectively on third and fourth rotating plate 33 and 34, only the 3rd with 90 ° of the 4th packaged mutual wrong shapes in position of separating spring, see Fig. 3 B and Fig. 3 C, touch at the two ends of the separation spring 5 rotating plate toe joint of both sides respectively.
Claims (1)
1, the clutch assembly that has auxiliary separation structure includes driving disc combination, central sleeve, platen, stage clip, lift slab, rotating plate and driven plate, and rotating plate cooperates with driven plate forms a plurality of friction pairs; It is characterized in that, in the outer diameter side uncinus center of the rotating plate that is in even bit or the 3rd, the 4th rotating plate through hole is set respectively, the separation spring is set in the through hole, the two ends of separating spring contact with the rotating plate tooth of both sides.
