Description

一种汽车用液力变矩器的长行程扭转减振器
技术领域
本发明属于汽车液力变矩器技术领域，具体涉及汽车液力变矩器的长行程扭转减振器。
背景技术
汽车液力变矩器应用于AT、CVT等形式自动档变速箱，是汽车传动系统中的一个关键零部件。传动系统中会产生扭转振动，如果这一振动的频率与传动系统的自振频率相吻合，就将发生共振，这对传动系统零件的寿命有很大影响。液力变矩器在设计过程中要求有减振功能，避免产生共振，缓解传动系统所受的冲击载荷。
随着汽车技术的不断发展，其变速箱控制向低档闭锁发展，现市场已实现10公里/h～20公里/h时变速箱指令变矩器闭锁。就液力变矩器而言，在低速比、高速差的工况下对承担减振功能的扭转减振器提出了越来越高的要求。
现有的液力变矩器的扭转减振器，具体的结构如图1和图2所示，包括从动板1、保持架2、8个大弹簧4以及4个小弹簧6；其中从动板1、保持架2装配后形成大弹簧4与小弹簧6的安装空间。保持架2的外边缘沿圆周方向均布安装8个驱动爪201，每两个驱动爪201之间安装一个大弹簧4；保持架2内部沿圆周均匀设置有四个窗口204，窗口204上设置一个大翻边203和一个小翻边202；四个小弹簧6卡装在四个窗口204内。工作时，涡轮的拨盘旋转，压缩大弹簧4从而实现减振的目的。
但是，上述结构中从动板和保持架在拨盘压缩大弹簧时均保持相对不动，减振的效果仅仅依靠一个大弹簧的压缩量，压缩量有限则减振效果有限，另外，大弹簧的选取也存在问题：
1、若大弹簧数量过少的话，采用普通直弹簧时，不易装配并且普通弹簧会出现装配偏差，会出现磨损。
2、若选用大弹簧选取弧形弹簧，则成本过大。
发明内容
为了解决背景技术中的问题，本发明提供了一种汽车用液力变矩器的长行程扭转减振器，液力变矩器的扭转减振器，采用串联式的大弹簧连接方式不仅装配方便并且其扭转减振角增大，大大提高了在闭锁传动时的减振效果。
本发明专利的技术方案是：
一种汽车用液力变矩器的长行程扭转减振器，包括从动板、保持架、大弹簧以及小弹簧；所述保持架的外边缘沿圆周方向均匀分布有N个驱动爪；
其改进之处是：
还包括弹簧盖；从动板、保持架与弹簧盖装配后形成大弹簧与小弹簧的安装空间；弹簧盖的外边缘沿圆周方向均匀分布N个拨爪，N个拨爪与N个驱动爪错位布置形成2N个尺寸相同的弹簧周向定位空间，每个弹簧周向定位空间内安装一个大弹簧；所述小弹簧数量为M个且沿圆周方向安装在保持架内部；N≥3，M≥3。
上述大弹簧选用椭圆截面螺旋压缩弹簧，大弹簧的压缩量为31.5mm，大弹簧两两串联后的压缩量为63mm。
本发明的优点在于：
1.本发明在弹簧盖上设置拨爪，不仅实现了大弹簧两两串联，增大了弹簧的压缩量，同时工作过程中大弹簧被压缩时弹簧盖与之一起运动，增大扭转减振角，提高减振效果。
2.本发明中采用大小两组弹簧实现两级减振设计，该两组弹簧包括2N(N≥3)个大弹簧和M(M≥3)个小弹簧，均切向分布，按照弹簧长度在46.9～76mm时大弹簧耐疲劳1000万次，二级扭转减振行程达到34.7°，扭矩为174N.m以上，扭转减振效果显著，提高乘坐舒适性。
3.本发明中的大弹簧采用两两普通直弹簧串联形成一组，功能相当于一个长行程弧形弹簧，增大扭转减振器的扭转减振角，可在较小的刚度下传递扭矩，同时避免了弧形弹簧的高成本。

具体实施方式
本发明中一种汽车用液力变矩器的长行程扭转减振器，参见图3-6，包括从动板1、保持架2与弹簧盖3，从动板1与保持架2由铆钉5连接，将弹簧盖3轴向固定，其中从动板1、保持架2与弹簧盖3装配后形成大弹簧4与小弹簧6的安装空间(其中，大弹簧为6个以及小弹簧为3个)。如图3所示，保持架2内部均匀设置有三个窗口204，窗口上设置一个大翻边203和一个小翻边202；三个小弹簧6卡装在三个窗口204内。
保持架的外边缘沿圆周方向均匀分布有3个驱动爪；如图4所示，弹簧盖的外边缘沿圆周方向均匀分布3个拨爪，3个拨爪与3个驱动爪错位布置形成6个尺寸相同的弹簧周向定位空间，每个弹簧周向定位空间内安装一个大弹簧(大弹簧采用普通直弹簧)，每两个相邻的大弹簧相当于串联连接，功能相当于一个长行程弧形弹簧，增大扭转减振器的扭转减振角，可在较小的刚度下传递扭矩，同时避免了弧形弹簧的高成本。
工作时，涡轮上的拨盘压缩一个大弹簧4，大弹簧4通过拨爪301将扭矩传递给下一个大弹簧，同时弹簧盖产生旋转，以实现长行程大扭转角的目的，提高其减振特性。
优选的是，大弹簧选用椭圆截面螺旋压缩弹簧，大弹簧的压缩量为31.5mm，大弹簧两两串联后的压缩量为63mm。
图7是减振弹簧特性曲线，在一定的弹簧安装空间内，弹簧压缩量大，扭转角大，减振效果显著。
