Description

离合器减震盖总成
技术领域
本发明涉及一种汽车离合器的核心零件领域，特别涉及一种离合器减震盖总成。
背景技术
离合器是汽车中连接发动机与变速箱的关键部件，起着离合扭矩的作用。压盘是离合器的核心零件，膜片弹簧与压盘上的支承山接触变形来提供压紧力，压盘大断面把压紧力均匀地施压在从动盘的摩擦片上。传统离合器压盘随盖总成一起旋转，在结合的瞬间，压盘与摩擦片产生摩擦力矩，对传动带的拉扯是阶跃式的，并因转速差太大，存在相对滑移，导致产热多。压盘就是一个巨大的铸铁件，材料一般为灰铁。通过传动带铆接于零件盖上，在发动机运行过程中，会随着飞轮一起旋转。
传动带在离合过程中会受到较大冲击，这是因为在结合过程中，压盘与摩擦片接触产生扭矩，会拉伸传动带。当完全结合后，由于发动机转速存在波动情况，会出现逆扭矩，从而压缩传动带。尤其是随着环保要求的不断提高，发动机逐渐向小排量方向发展，比如三缸发动机、停缸等技术，虽然这些技术有助于燃油经济性的提高，不过却提高了转速的不稳定性及震动，这对离合器传动带来说也是巨大的挑战。
除此之外，离合器在设计之初会考虑滑摩功。滑摩功就是在结合过程中，压盘与摩擦片相会摩擦产生的热量。其中有个关键参数滑摩时间，滑摩时间越长产生的热量越大。因为要保证离合器在工作过程中温度不能太高，一般会通过增加压盘质量来吸收和释放滑摩热量。因此导致在一些大功率的动力平台上，压盘尺寸都很大。
传统的动力传输过程中，减震机构只布置于飞轮与离合器从动盘上，如图1所示。
以上是本申请需要着重改善的地方。
发明内容
本发明所要解决的技术问题是要提供一种离合器减震盖总成，提高发动机传动系统的减震效果，保护离合器传动带，减小滑摩功。
为了解决以上的技术问题，本发明提供了一种离合器减震盖总成，离合器盖总成上增加了大转角减震压盘，所述大转角减震压盘包括主压盘和次级压盘，主压盘包括大角度减震部件和次级压盘连接组件，次级压盘与次级压盘连接组件进行连接，主压盘通过三搭子与传动带铆接，次级压盘与从动盘柔性结合，膜片弹簧通过主压盘的支承山传递压紧力，再通过次级压盘连接组件传递压紧力，施压于从动盘上的摩擦片上，带动从动盘旋转。
所述大角度减震部件分布于主压盘的内腔，包括独段的弹性部件，或多段的弹性部件，及每段弹性部件两端的阻尼滑块，大角度减震部件的一端与次级压盘连接组件接触，另一端与主压盘的外壳体接触，次级压盘与主压盘存在转速速差时，大角度减震部件开启减震功能。
所述次级压盘，是指具有一个与从动盘摩擦面接触的从动盘受力面，所述从动盘受力面最大外径比从动盘摩擦片最大外径大1-2mm，内径比从动盘摩擦片内径小1-2mm。所述次级压盘还设有与传力板铆接的铆钉孔，铆钉孔均匀分布于次级压盘的内圈。
所述次级压盘连接组件包括传力板、铆钉、蝶形弹簧、Z型圆环和滚子。所述传力板用于传递扭力和压紧力，且仅在垂直于传动轴一定距离的两个面之间运动。所述传力板通过铆钉与次级压盘铆接在一起，传力板的阻尼滑块受力面与大角度减震部件中的阻尼滑块接触，传力板的推力轴承支撑面与滚子接触。蝶形弹簧一端与Z型圆环接触，另一端与传力板接触，起到支撑传力板的作用。Z型圆环一端与主压盘盖板接触，另一端与蝶形弹簧接触，起到限定蝶形弹簧位置的作用。
本发明的优越功效在于：
1）本发明通过改变传统压盘的结构，将压盘分为主压盘和次压盘，赋予压盘以减震功能，使传动系统的减震机构有更多的布置选择，有效地增强了传动系统的减震性；
2）可以代替双质量飞轮的功效，降低车辆制造成本；
3）起到保护传动带的作用；
4）本发明压盘可以柔性地与从动盘结合，对传动带的受力是抛物线式，次级压盘快速与从动盘结合，缩短了结合时间，从而减小了滑摩功。

具体实施方式
以下结合附图对本发明的实施例进行详细说明。
图2示出了本发明实施例的离合器减震盖总成的结构示意图。如图2-图6所示，本发明提供了一种离合器减震盖总成，离合器盖总成上增加了大转角减震压盘，所述大转角减震压盘包括主压盘和次级压盘9，主压盘包括大角度减震部件和次级压盘连接组件，次级压盘9与次级压盘连接组件进行连接，主压盘通过三搭子102与传动带铆接，次级压盘9与从动盘柔性结合，碟形弹簧5通过主压盘的支承山101传递压紧力，再通过次级压盘连接组件传递压紧力，施压于从动盘上的摩擦片上，带动从动盘旋转。
所述大角度减震部件分布于主压盘的内腔，包括独段的弹性部件，或多段的弹性部件，及每段弹性部件两端的阻尼滑块，本实施例中大角度减震部件是选用单根长弹簧，减震弹簧8的一端与次级压盘连接组件接触，另一端与主压盘外壳体1接触，次级压盘9与主压盘存在转速速差时，传力板2受到主压盘中阻尼滑块的力，和或传力板2的力施加到主压盘中阻尼滑块上，从而大角度减震弹簧8开始工作。
所述次级压盘9，是指具有一个与从动盘摩擦面接触的从动盘受力面902，所述从动盘受力面902最大外径比从动盘摩擦片最大外径大1-2mm，内径比从动盘摩擦片内径小1-2mm。所述次级压盘9还设有与传力板2铆接的铆钉孔901，铆钉孔901均匀分布于次级压盘9的内圈。
所述次级压盘连接组件包括传力板2、铆钉6、蝶形弹簧5、Z型圆环4和滚子7。所述传力板2仅在垂直于传动轴一定距离的两个面之间运动。所述传力板是用于传递扭力和压紧力，其中压紧力传递通过限位装置或推力轴承机构实现，本实施例选用推力调心轴承，其中201相当于推力轴承的内圈，103相当于推力轴承的外圈。所述传力板2通过铆钉6与次级压盘9铆接在一起，传力板2的阻尼滑块受力面202与大角度减震部件中的阻尼滑块接触，传力板2的推力轴承支撑面与滚子7接触。蝶形弹簧5一端与Z型圆环4接触，另一端与传力板2接触，起到支撑传力板2的作用。Z型圆环4一端与主压盘盖板3接触，另一端与蝶形弹簧5接触，起到限定蝶形弹簧5位置的作用。
本发明离合器减震盖总成在结合过程中蝶形弹簧5施加压力于主压盘上，该压力再通过滚子7施加于传力板2上，从而让次级压盘从动盘受力面902压向从动盘摩擦片。相较于传统压盘，本发明离合器盖总成增加了大角度减震部件，因此该结合过程是柔性的，降低了滑磨时间，从而减小了滑磨功。同时传动带的受力变化也更加平顺，保护了传动带。位于主压盘内腔的大角度减震部件，减震弹簧8利用内腔空间布置独段减震弹簧或多段减震弹簧，从而提高了减震效果。
以上所述仅为本发明的优先实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
