Definitions

• the present invention relates to a clutch device in which a clutch disk facing is arranged between a flywheel and a pre-sharp rate, and the clutch is intermittently intermittently moved by an axial movement of the pressure rate plate.
• FIG. 2 shows a conventional example of a pull-type clutch.
• the outer fulcrum is supported by the clutch cover 2 and the intermediate fulcrum is the pre-sharp plate 6.
• contact, c i.e. the diaphragm spring 3 1 inner peripheral support portion is engaged with the Lelie Zusuri over Bed 3 3 and serves to impart imposition load plexes sharp rate 6, Lelie Zusu Li when release - Bed It serves as a transmission lever for transmitting the release from 3 to pressure plate 6.
• the structure of the diaphragm spring 31 itself becomes a complicated shape having a so-called many radial slits and the like. Trouble occurs, transmission efficiency of release force is not good, and release operation performance is unstable.
• An object of the present invention is to eliminate the loss of the release stroke and improve the release operation performance.
• the present invention provides a clutch in which a clutch disk facing is arranged between a flywheel and a press plate, and the clutch is interrupted by moving the press plate in the axial direction.
• a projection part extending toward the axis is integrally formed on the plate shear plate, and a release bearing for directly engaging a release bearing with the projection and supporting the release bearing is provided.
• the valve can be moved in the axial direction by a hydraulic cylinder.
• FIG. 1 is a longitudinal sectional view of a clutch device to which the present invention is applied
• FIG. 2 is a longitudinal sectional view of a conventional example.
• FIG. 1 showing a longitudinal sectional view of a clutch device to which the present invention is applied
• a flywheel 1 of the clutch is connected to an engine output shaft via a flywheel damper F.
• the facing 9 of the clutch disk 5 and the pre-sharp rate 6 are arranged in order from the flywheel side.
• the clutch disk 5 has an inner spline hub 5a spline-fitted to an output shaft (not shown).
• the pre-sharp plate 6 has its outer peripheral projection 6 c clamped through a plurality of strap plates 12. It is connected to the tab cover 2 so as to be movable in the axial direction.
• the rear end face of the pressure plate 6 is formed with a full clamp 6b projecting rearward.
• An axis is provided between the full clamp 6b and the projection 2a of the rear end wall of the clutch cover 2.
• a disc spring 15 is contracted by itself in the directional compression, and the disc spring 15 urges the pre-sharper plate 6 forward to press against the facing 9.
• the inner peripheral end of the disc spring 15 is fixed to the funnel clamland 6b by the clip 10 and the clip 10 is fixed to the pressure plate 6 by the rebate 11 .
• annular projection 6a protruding toward the axis is integrally formed on the inner peripheral surface of the rear part of the pressure plate 6, an annular projection 6a protruding toward the axis is integrally formed.
• an outer race of a relief bearing 20 arranged on the axis side is provided on the other hand.
• An outwardly extending annular flange portion 22a is integrally formed with the projection 22.
• the rear surface of the annular flange portion 22a is in contact with the projection 6a.
• the inner race 21 of the release bearing 20 is fixed to the release sleeve 24 so that it cannot move in the axial direction.
• the rear part of the release sleeve 24 is axially movably fitted to the hydraulic cylinder 23 via seals 25 and 26, and the oil chamber 27 in the hydraulic cylinder 23 is an oil port. It communicates with a hydraulic control mechanism (not shown) via 30. By supplying hydraulic oil into the oil chamber 27, the release sleeve 24 is moved rearward.
• a conical stopper / damper spring 28 is disposed in the oil chamber 27 so as to be axially compressible.
• FIG. 1 shows the clutch connection state, in which the oil chamber 27 of the hydraulic cylinder 23 is in an open state, and the pressure plate 6 is applied to the facing 9 by the elastic force of the disc spring 15. We are in pressure contact.
• the projection 6a on the inner peripheral side of the pre-sharp plate 6 is an annular projection, but it may be a projection having a structure in which a slit for cooling air is formed radially.
• the present invention is not limited to a structure in which the flywheel 1 is directly connected to the engine output shaft via a flywheel damper F as shown in FIG. It can also be applied to clutches that have a damper on the clutch disk.
• a sleeve that directly engages the projection 6 a formed on the pressure plate 6 with the release bearing 20 and supports the ⁇ 0 release bearing 20. Since the hydraulic cylinder 23 allows the axis 24 to move in the axial direction, the hydraulic cylinder 23 does not require a lever component such as a diaphragm spring. Direct transmission is possible, so there is no loss of the release opening, and the transmission efficiency of the release force is improved and the release operation performance is improved.
• a spring having a simple structure that can be simply contracted between the clutch cover 12 and the pressure plate 6 can be used.
