Description

技术领域：
本发明涉及一种双质量飞轮总成， 属于汽车配件制造技术领域。 背景技术
双质量飞轮于上世纪 80年代末出现在汽车上，所谓双质量飞轮， 就是将原来的一个飞轮分成两个部分， 一部分保留在原来发动机一侧 的位置上， 用于起动和传递发动机的转动扭矩， 称为初级质量。 另一 部分则放置在传动系变速器一侧， 用于提高变速器的转动惯量， 称为 次级质量。 由于次级质量能在不增加飞轮的惯性矩的前提下提高传动 系的惯性矩， 令共振转速下降到怠速转速以下。 例如德国鲁克 (LUK) 公司的发动机双质量飞轮将共振转速从 1300转 /分降到了 300转 / 分。 目前一般汽车怠速在 800转 /分左右， 也就是说在任何情况下， 出现共振转速都在发动机运行的转速范围以外， 只有在发动机刚起动 和停机时才会越过共振转速。 双质量飞轮是当前汽车上隔振减振效果 最好的装置， DE3721712C2 , DE4117582AK DE4117579A 1等均涉及这 种装置。上世纪 90年代以来在欧洲得到广泛推广， 已从高级轿车推广 到中级轿车， 尤其是柴油机动车。 CN200710192763. 0 公开了一种双 质量飞轮， 该双质量飞轮由一个可与发动机输出轴相连接的初级质量 和一个可与变速器输入件相连接的次级质量组成， 该初级质量和该次 级质量借助于至少一个支承装置同轴心地且在轴向上彼此相对地定 位， 并且可抵抗一个具有能量储存器、 尤其是螺旋压簧的减振装置作 用受限制地彼此相对扭转。 CN 200820071783. 2公开了一种双质量飞 轮， 采用滑动轴承替代传统的滚珠轴承， 其齿圈与第一质量壳体过盈 配合连接， 弧型弹簧式阻尼机构位于第一质量壳体的腔中， 传力板铆 接在第二质量盘上， 轴承座与第一质量壳体铆接， 信号轮与该第一质 量壳体悍接， 滑动轴承与第二质量盘过盈配合连接， 该滑动轴承与轴 承座滑动配合连接。 上述的各种双质量飞轮虽取得了相当的成绩， 但 其初级质量与次级质量的连接不甚理想， 其整体价格也较高。 发明内容
