在离合器从分离到接合的过程中，摩擦片与飞轮和压盘之间要发生摩擦，产生大量热量，这些热量需要及时散出，以避免摩擦片因温度过高而损坏。由于需要保证自身强度以避免受力变形，现有的离合器盖如中国授权公告号CN210484452U，一种散热良好的离合器盖板公开的技术方案：“离合器盖板本体的外壁上设置有安装孔，以使离合器盖板本体安装固定；所述离合器盖板本体与压盘接触的a端面上设置有第一散热孔以及b端面设置有第二散热孔；散热件，所述散热件设置在离合器盖板本体的中部位置，且位于第一散热孔与第二散热孔之间，所述散热件为硬性材质”。该技术方案公开的散热件为铜质材质，比较柔软，将铜质材质的散热件设置在离合器盖板本体的中部位置，结构设计不合理，会导致离合器盖板强度不好，容易受力变形；膜片弹簧无定位件，安装到离合器盖内后会导致膜片弹簧定位不可靠，实用性差。In the process of the clutch from separation to engagement, friction occurs between the friction plate, the flywheel and the pressure plate, and a large amount of heat is generated, which needs to be dissipated in time to avoid damage to the friction plate due to excessive temperature. Due to the need to ensure its own strength to avoid stress deformation, the existing clutch cover, such as the Chinese Authorized Notice No. CN210484452U, a disclosed technical solution of a clutch cover with good heat dissipation: "The outer wall of the clutch cover body is provided with mounting holes to The clutch cover plate body is installed and fixed; the a end surface of the clutch cover plate body in contact with the pressure plate is provided with a first heat dissipation hole and the b end surface is provided with a second heat dissipation hole; the heat dissipation part is arranged on the clutch cover plate The middle position of the body, and between the first heat dissipation hole and the second heat dissipation hole, the heat dissipation element is made of hard material". The heat sink disclosed in this technical solution is made of copper, which is relatively soft. If the copper heat sink is placed in the middle of the clutch cover body, the structural design is unreasonable, which will lead to poor strength of the clutch cover and easy deformation under force. ; Diaphragm spring has no locating parts, after being installed in the clutch cover, it will lead to unreliable positioning of diaphragm spring and poor practicability.
