Definitions

• the present invention has a diaphragm spring with an enlarged opening at the outer end of the radial slit, and the outer fulcrum of the diaphragm spring is supported by a clutch force bar.
• the fulcrum of the I-plate contacts the press plate of the press plate, the inner fulcrum is supported by the release ih support, and the release support is released. This is related to the bullet clutch that releases the clutch by pulling it toward $ J on the opposite side of the lesser plate side.
• this type of pull type clutch is supported by the outer fulcrum C1 of the diaphragm spring 8 (clutch cover) and the inner fulcrum C2 is pressed. It contacts the file clamp 1 ⁇ of the shear plate 7, and the inner fulcrum C 3 is engaged with the release bearing 12.
• the pressure plate 7 and the clutch cover 1 are connected so as to be able to rotate integrally via a strap plate 4, and the inner fulcrum C 3 is connected to the release plate 12 with the release plate 12. By pulling it backward, the elastic force of the strap plate 4 moves the brusher plate 7 rearward, so that the clutch can be cut.
• an air introducing body 48 having an air scoop portion 49 is provided for sending cooling air to the pressure plate 7, and the guide plate 48 is used to externally press the pressure plate from the outside. Air is introduced into seven sections.
• the purpose of the present invention is to improve the shape of the air introduction body to ensure that the press plate moves in the direction of the clutch, and that the engine moves. This is to eliminate the phenomena caused by dragging.
• Masaaki Akira included a diaphragm spring with a widened opening at the outer end of the radial slit, and clamped the outer fulcrum of the diaphragm spring. Fulcrum, and the fulcrum of the middle abuts against the file clamp of the brake blade, and the inner fulcrum is supported by the release bearing ⁇ After the diaphragm spring in a bull tie clutch that releases the clutch by pulling the release bearing axially rearward on the side opposite to the pressure plate side.
• An air introduction body is disposed on the air guide body, and the mounting leg of the air guide body is fixed to the presser plate through the opening, and a projection is formed on the air introduction body so as to protrude toward the diaphragm spring. And the protrusion and the plate of the presser plate It is ⁇ the middle fulcrum of the die arrow La Musupuri ring in fig with Noreku Ramla down mode.
• the diaphragm spring moves (deforms) backward using the outer fulcrum as a fixed fulcrum.
• Middle of diaphragm spring Since the fulcrum is sandwiched between the flange of the press plate and the projection for air introduction, the fulcrum is integrated with the diaphragm spring. The shear plate will move backwards, and the clutch will surely cut.
• the pressure plate is in contact with and supported by the diaphragm spring, the pressure between the clutch disk and the pressure plate caused by engine vibration is increased. Prevents contact and no dragging.
• the air introducing body takes in the outside air from the scoop part, supplies it to the press plate, and cools the brake plate.
• FIG. 1 is a longitudinal section of a pull-out clutch to which the present invention is applied.
• FIG. 2 is a perspective view of FIG. 1 and FIG. 2 is a longitudinal section of the conventional example.
• FIG. 1 shows a pull-type clutch to which the present invention is applied.
• the clutch disc 5 has its inner peripheral spline hub spline-fitted to the output peg 3, and the outer periphery of the clutch disk 5 has a ferrule.
• Thing 6 is provided.
• the flywheel 2 is arranged on the front side (engine side) of the casting 6, and the presser plate 7 is arranged on the rear side thereof. 7 is connected and supported to the clutch cover 1 by a plurality of strap plates 4 so as to be movable in the direction, and is urged rearward (clutch cut side) by the elastic force of the strap plate 4.
• Clutch cover 1 is connected to the outer edge of flywheel 2.
• the diaphragm spring 8 is arranged on the rear side of the brake plate 7, and its outer fulcrum C 1 is supported by the M curved portion of the clutch cover 1 via the ring Q, and the width fulcrum C 2 is in contact with the pressure plate 7 of the pressure plate 7], and the inner fulcrum C 3 is related to the release: S 12.
• a plurality of file lamps 1 ⁇ are formed at intervals in the circumferential direction.
• an air introducing body 18 for arranging the air gap part 2 is arranged on the rear side of the diaphragm spring 8.
• Fig. 2 shows a perspective partial view of Fig. 1.
• the diaphragm spring 8 has a number of radial slits 16, and the radially outer end of each slit 16 is enlarged. Oval holes) 17 are formed.
• the air introducing body 18 has a plurality of mounting legs 27 and a plurality of air scoop portions 2 ⁇ integrally on the inner side of the annular main body portion 21, and the mounting legs 27 and the scoop portion 2 are integrated.
• the holes are respectively arranged at positions corresponding to 17 in the opening.
• the mounting legs 27 are arranged, for example, at positions corresponding to every two openings 17, and the scoop portions 2 ⁇ are arranged at positions corresponding to the openings between the mounting legs 27.
• the air scoop portion 20 is formed so as to protrude rearward. The end portion in the rotation direction R side and the inside end portion are opened, and the inside is pressurized through the opening portion 17. — Communicates with the front side.
• the mounting leg 27 passes through the opening 17 to the upper surface (rear surface) of the press plate 7, and is attached to the press plate 7 by the mounting bolt 25.
• the cross-sectional shape of the ⁇ -shaped main body 21 is formed to be inclined toward the diaphragm spring side (front side) as it goes inward, and the front-projecting shape is formed at the cylinder corresponding to the intermediate support point C 2.
• the projection 23 is formed, and the intermediate fulcrum C 2 of the diaphragm spring 8 is formed by the question of the projection 23 and the fan-load land 10 of the press plate 7. It is pinched.
• the pressure plate 7 is always in contact with and supported by the diaphragm spring 8, the movement of the pressure plate 7 due to engine vibration is prevented, and the engine movement is prevented. As a result, the flushing 6 and the presser plate 7 do not come into contact with each other, and no entrainment occurs.
• Air can be taken from the opening in the direction of rotation of the trap unit 20 by rotation in the direction of the arrow R in FIG. Air is supplied to the pressure plate 7 through 7 to cool the pressure plate 7.
• the air introducing body 18 in the embodiment shown in the drawing has the force of having the annular main body 21, and 3 ⁇ 4 the main body 21 is divided into two or three parts to form a diaphragm spring. It is also possible to harden.
• a raised portion 2 is formed on an air guide 18 fixed to a press plate 7, and a pressurized portion is formed with the raised portion 23. Since the diaphragm 10 of FIG. 7 sandwiches the fulcrum C 2 of the diaphragm spring 8 at the diaphragm spring 10, when the clutch release operation is performed, the diaphragm 7 is not used. The unit moves in the direction of cutting along with the spring 8, and the clutch is cut reliably.
• the release operation of the clutch can be reliably performed.
• the protrusions 23 are formed on the air introduction body 18 as parts that perform the functions of the clip for holding the diaphragm spring of the push type clutch and the M. Saves number.
• the pull-type clutch assembly according to the present invention is suitable for a clutch for an F] vehicle train, and is particularly used for a twin clutch having a 1 mm clutch disk. Then, the effect of the dragging prevention is remarkable.
