Abstract
The utility model discloses a friction plate formula clutch, including center sleeve, pressure disk, initiative friction disc and driven steel sheet, the limit portion of upper story initiative friction disc or lower floor initiative friction disc is provided with spacing post, and the cover has buffer spring on the spacing post, and buffer spring's one end top is on upper story initiative friction disc, and buffer spring's the other end top is on lower floor initiative friction disc. When the clutch is separated, the buffer spring applies thrust to the uppermost layer of driving friction plate and the lowermost layer of driving friction plate, so that the friction plates can be separated from the steel sheet in a state of being parallel to each other, and the problem that the friction plates are not completely separated from the driven steel sheet due to adhesion of lubricating oil and deflection of the friction plates can be solved; and when the clutch is engaged, the buffer spring can prolong the combination time of the driving friction plate and the driven steel sheet, so that the combination of the clutch is softer, and the impact phenomenon of a vehicle when the clutch is engaged can be reduced.
Description
Technical Field
The utility model relates to a clutch technical field, in particular to friction plate formula clutch.
Background
A friction plate type clutch for a motorcycle comprises a center sleeve assembly and an outer cover assembly, wherein as shown in the attached figure 1 of the specification, the existing center sleeve assembly comprises a center sleeve 1, a pressure plate 2, a cover plate 3, a spring 4, a driving friction plate 5, a driven steel sheet 6 and other parts, the driving friction plate and the driven steel sheet sleeve are sleeved on the center sleeve in a staggered and overlapped mode, and transmission teeth matched with tooth grooves in the outer circumference of the center sleeve are arranged on the inner diameter of the driven steel sheet. In the process of the joint transmission of the driving friction plate 5 and the driven steel sheet 6, the power of the engine crankshaft is transmitted to the outer cover assembly, the outer cover assembly transmits the power to the driving friction plate 5 of the center sleeve assembly, the driving friction plate 5 transmits the power to the driven steel sheet 6, the driven steel sheet 6 transmits the power to the center sleeve 1, and the center sleeve transmits the power to the driven shaft for output. When the cover plate 3 is pushed by the clutch push rod to overcome the pushing force of the spring to loosen the pressure plate 2, the driving friction plate 5 and the driven steel sheet 6 are separated from each other, so that the power is cut off.
However, when the clutch works, lubricating oil is arranged between the driving friction plate and the driven friction plate for lubricating and cooling, and the lubricating oil is easy to cause incomplete separation of the driving friction plate 5 and the driven steel plate 6 when the clutch is separated; when the clutch is combined, when the push rod of the clutch is retracted, the pressure plate 2 can return rapidly to tightly press the driving friction plate 5 and the driven steel sheet 6 to be combined under the action of the thrust of the spring 4, and due to the lack of buffer time, the driving friction plate 5 and the driven steel sheet 6 can be combined rapidly to enable a vehicle to generate a collision phenomenon, so that the driving comfort is reduced.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides a friction plate clutch to solve the technical problems in the prior art that the driving friction plate and the driven steel plate are not completely separated when the friction plate clutch is separated, and the vehicle is likely to generate a collision phenomenon when the clutch is engaged.
The utility model discloses friction plate formula clutch, including center cover, pressure disk, initiative friction disc and driven steel sheet, the crisscross overlapping cover of initiative friction disc and driven steel sheet is put on the center cover, and the limit portion of upper layer initiative friction disc or lower layer initiative friction disc is provided with two piece at least spacing posts, spacing post evenly distributed on the circumferencial direction of initiative friction disc, and the cover has buffer spring on the spacing post, buffer spring's one end pushes up on upper layer initiative friction disc, and buffer spring's the other end pushes up on lower layer initiative friction disc; when the driving friction plate and the driven steel sheet are in an engaged state, the buffer spring is in a compressed state.
The utility model has the advantages that:
the utility model discloses friction plate formula clutch, it is through setting up buffer spring between the top layer initiative friction disc and the bottom layer initiative friction disc, when the clutch separation, buffer spring exerts thrust to the top layer initiative friction disc and the bottom layer initiative friction disc, makes the friction disc keep the state that is parallel to each other and the steel sheet separation to avoided lubricating oil adhesion and friction disc incline to lead to with the not thorough problem of driven steel sheet separation; and in the process of clutch engagement and pressing engagement of the driving friction plate and the charging friction plate by the pressure plate, the buffer spring can prolong the combination time of the driving friction plate and the driven steel sheet, so that the combination of the clutch is softer, the power transmission is smoother, the impact phenomenon of a vehicle when the clutch is engaged can be effectively reduced, and the driving comfort of the vehicle can be improved.

FIG. 2 is a schematic sectional view of a friction plate clutch according to an embodiment.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in the figures, the friction plate clutch of the present embodiment includes a central sleeve 1, a pressure plate 2, a driving friction plate 5 and a driven steel plate 6, the driving friction plate and the driven steel plate are alternatively overlapped on the central sleeve, and at least two limiting posts 7 are disposed at an edge of the driving friction plate at the uppermost layer. The limiting columns are uniformly distributed in the circumferential direction of the active friction plates, the limiting columns are sleeved with buffer springs 8, one ends of the buffer springs are abutted against the uppermost layer of active friction plate, and the other ends of the buffer springs are abutted against the lowermost layer of active friction plate; when the driving friction plate and the driven steel sheet are in an engaged state, the buffer spring is in a compressed state.
In the friction plate type clutch, the buffer spring is arranged between the uppermost layer of driving friction plate and the lowermost layer of driving friction plate, and when the clutch is separated, the buffer spring applies thrust to the uppermost layer of driving friction plate and the lowermost layer of driving friction plate, so that the friction plates can be separated from the steel sheet in a state of being parallel to each other, and the problem of incomplete separation from the driven steel sheet caused by adhesion of lubricating oil and deflection of the friction plates is solved; and in the process of clutch engagement and pressing engagement of the driving friction plate and the charging friction plate by the pressure plate, the buffer spring can prolong the combination time of the driving friction plate and the driven steel sheet, so that the combination of the clutch is softer, the power transmission is smoother, the impact phenomenon of a vehicle when the clutch is engaged can be effectively reduced, and the driving comfort of the vehicle can be improved.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
