Definitions
- the present invention relates to a clutch device having a mechanism for pressing a clutch disk with a pressure plate.
- a clutch device is provided on a power transmission system path between the engine and the transmission in order to prevent the rotational power of the engine from being transmitted to the transmission at the time of starting the engine or shifting.
- a clutch operating force is transmitted through a release mechanism such as a hydraulic mechanism and a link mechanism by manual operation (manual operation, stepping operation, etc.) of an operation mechanism such as a clutch lever and a clutch pedal. And can be intermittent.
- the clutch device generally has a mechanism that presses a clutch disk that transmits rotational power to a transmission with a pressure plate against a flywheel that transmits rotational power of the engine.
- the pressure plate is biased toward the clutch disk by a diaphragm spring that can be operated by a release mechanism.
- the clutch disk is sandwiched between the flywheel and the pressure plate and frictionally engaged, whereby the rotational power of the engine is transmitted to the transmission.
- the clutch device when the rotational power from the engine is transmitted to the transmission, heat is generated by friction on the friction surface between the pressure plate and the clutch disk, and the back surface of the pressure plate (the surface on the diaphragm spring side) and the friction surface This causes a temperature difference between the back surface and the friction surface of the pressure plate, resulting in a difference in the amount of elongation due to thermal expansion, and the pressure plate is deformed.
- the torque transmission capacity decreases, which may cause problems such as clutch slippage and temperature rise.
- the surface changes toward the inner periphery), and the transmission torque becomes smaller. Further, due to the warping of the pressure plate 117, the area of the friction surface between the pressure plate 117 and the clutch disk 30 is reduced, and if slip occurs on the friction surface, the temperature is likely to rise rapidly, the friction material 31 deteriorates, and the friction coefficient increases. The transmission torque decreases. Eventually, the engine torque cannot be transmitted to the wheels, and there is a risk that the vehicle cannot climb up a slope.
- the pressure plate is constituted by a plurality of annular plate-like plate members, and is long in the radial direction formed on these plate members.
- a friction clutch in which a rivet is inserted into a hole and caulked with a wave spring interposed.

Moreover, since the pressure plate described in Patent Document 1 is divided into a plurality of plate members, the strength is lower than that of the integrated pressure plate, and heat dissipation (heat transfer) is reduced. Further, in the pressure plate described in Patent Document 1, since the plate members can be relatively moved in the radial direction, the friction material of the clutch disk deteriorates more than the integrated pressure plate due to the eccentricity of the plate members. May be easier.

- the back surface of the pressure plate can follow the elongation of the friction surface of the pressure plate during thermal expansion. Warpage during thermal expansion can be reduced.
- the bottom surface of the groove portion of the pressure plate is close to the friction surface, and the difference between the average temperature of the back surface of the pressure plate and the temperature of the friction surface is reduced, so that it is possible to reduce the warp during the thermal expansion of the pressure plate.
- the pressure plate is an integrated type, the number of parts is larger than that of the assembly type pressure plate, the cost is increased, the strength is lowered, the heat dissipation (heat conductivity) is lowered, the friction material of the clutch disk is deteriorated, etc. Disadvantages can be suppressed.

Abstract
Description
車両においては、エンジン始動時や変速時などにおいてエンジンの回転動力を変速機に伝達しないようにするために、エンジンと変速機との間の動力伝達系路上にクラッチ装置が設けられている。クラッチ装置は、クラッチレバー、クラッチペダル等の操作機構のマニュアル操作(手動操作、踏込操作等)により、油圧機構、リンク機構等のレリーズ機構を介してクラッチ操作力が伝達されて、エンジンと変速機とが断続可能になっている。クラッチ装置は、一般的に、変速機に回転動力を伝達するクラッチディスクを、エンジンの回転動力が伝達されるフライホイールに対して、プレッシャプレートで押付ける機構を有する。プレッシャプレートは、レリーズ機構によって操作可能なダイヤフラムスプリングによってクラッチディスク側に付勢されている。クラッチディスクがフライホイールとプレッシャプレートとの間に挟み込まれて摩擦係合することで、エンジンの回転動力が変速機に伝達される。
しかしながら、特許文献1のような組立型のプレッシャプレートでは、部品点数が多く、一体型のプレッシャプレートよりもコストがかかってしまう。また、特許文献1に記載のプレッシャプレートは複数のプレート部材に分かれているため、一体型のプレッシャプレートよりも強度が低く、放熱性(伝熱性)が低くなってしまう。さらに、特許文献1に記載のプレッシャプレートでは、プレート部材間が径方向に相対移動可能になっているため、プレート部材の偏芯によって、一体型のプレッシャプレートよりもクラッチディスクの摩擦材が劣化しやすくなる可能性がある。
