The invention relates to an improved wet double clutch, with an axle sleeve on the left side of the main hub, the outer cylindrical cylinder of the shaft sleeve is connected with the piston, the inner cylindrical cylinder of the shaft sleeve is connected with the outer circumference of the main hub, and the left end of the cylindrical surface of the shaft sleeve is equipped with a conical opening and corresponds to the pressure hole position on the main hub, and the right of the pressure oil hole is on the right. The side hole edge matches the small end of the conical opening, the right end of the cylindrical surface in the shaft sleeve is provided with a sealing surface, and a sealing ring is arranged between the main rotary hub and the sealing surface of the shaft sleeve. The invention reduces the overall axial distance of the clutch, is more compact, and is favorable for customer arrangement, and will adapt to more vehicle environment. Lightweight is achieved by decreasing axial length, which is in line with the current development direction of vehicle. The axial length reduces to the gear shaft and other components in the axial length to extend the axial expansion space, and can expand the design of greater torque transmission, but does not increase the axial length of the existing transmission, and the parts are less, and the cost is lower.

一种改进的湿式双离合器
本专利技术涉及汽车双离合变速器技术,具体是涉及一种改进的湿式双离合器。
技术介绍
近年来,双离合变速器(DCT)由于其优秀的性能表现受到越来越多汽车厂商的青睐,其中双离合器作为双离合变速器的核心部件,其性能及成本对于双离合器来说就显得尤为关键。双离合器分为干式和湿式,都具有两个离合器,其中湿式双离合器结构更为复杂,结构尺寸也相对较大。中国专利公开了一种“用于双离合器变速器的双离合器组件”(公告号:CN104768786A),其径向从外到内依次布置第一离合器,第二离合器,两个轴向平行布置的活塞结构。其中活塞结构中通常包含活塞、活塞盖、支撑板、卡环、弹簧组件、平衡活塞以及支撑这些零部件的主转毂,由于主转毂上从左至右依次需要布置卡环、支撑板、活塞盖、油孔、活塞及相应活塞行程,因此轴向尺寸较大。弹簧组件轴向上也因平衡活塞及平衡活塞右侧的冷却油道导致其轴向尺寸偏大。从而导致双离合器轴向尺寸大,双离合变速器轴向尺寸大,最终影响整车布置。
技术实现思路
针对上述技术问题,本专利技术提供一种湿式双离合器,使该湿式离合器及装有该湿式双离合器的变速器轴向更紧凑、零件更少、重量更轻、成本更低,可在有限空间拓展设计更大扭矩。为实现上述目的,本专利技术采用以下技术方案。一种改进的湿式双离合器,包括主转毂,所述主转毂上设有压力油孔和冷却油孔,在主转毂的左侧套装有轴套,轴套的外圆柱面与活塞连接,轴套的内圆柱面与主转毂外周连接;轴套内圆柱面的左端设有锥形开口且与主转毂上的压力油孔位置相对应,压力油孔出口的右侧孔边与锥形开口的小端相匹配,轴套内圆柱面的右端设有密封面,主 ...
