摘要： The purpose of the present invention is to provide a clutch seal capable of increasing the durability of a membrane section, which is a component of the seal and is obtained from a rubber-like elastic body. Additionally, the purpose is to provide a clutch seal capable of limiting the accumulation of working fluid on the concave surface of the membrane section. Said purposes are achieved by a clutch seal, which: is a ring-shaped seal interposed between a clutch plate and a piston for pressing the clutch plate in a dry clutch; has a middle ring that is fixed to the piston between an outer ring and an inner ring that are fixed to the clutch housing; and has membrane sections between the outer ring and the middle ring and between the inner ring and the middle ring, respectively, the membrane sections being obtained from rubber-like elastic bodies. The clutch seal is characterized in that, in the initial shape of the membrane sections, the middle ring is disposed at an intermediate position of the stroke thereof. The clutch seal is also characterized in that the straight portion of the outer membrane section has an angle of inclination oriented so that the radius decreases from a first fold back portion to a second foldback portion.

摘要翻译：本发明的目的是提供一种离合器密封件，该离合器密封件能够提高作为密封件的部件的膜部分的耐久性，并且由橡胶状弹性体获得。此外，目的是提供一种能够限制工作流体在膜部分的凹面上的积聚的离合器密封件。所述目的通过离合器密封件实现，该离合器密封件是插入在离合器板和活塞之间的环形密封件，用于将离合器板压在干式离合器中; 具有固定到固定到离合器壳体的外圈和内圈之间的活塞的中间环; 并且在外圈和中间环之间以及内圈和中间环之间分别具有膜部分，膜部分由橡胶状弹性体获得。离合器密封件的特征在于，在膜部的初始形状中，中间环设置在其行程的中间位置。离合器密封件的特征还在于，外膜部分的直线部分具有倾斜角度，使得半径从第一折回部分减小到第二折回部分。
