Description

一种用于混合动力车的扭转减振器
技术领域
本发明涉及汽车制造的混合动力系统，具体是一种用于混合动力车的扭转减振器。
背景技术
现有客车混合动力系统中，在发动机与电机之间的扭矩传递存在很大的冲击，若直接以轴连接，易造成断轴故障。因此，发动机与电机之间常以传统离合器或单独的离合器中的从动盘连接。前者占用空间大，常不能正常与整车匹配，且盖总成转动惯量大，将进一步加剧冲击破坏；后者安装空间允许，但要求从动盘能够承受巨大的冲击，常造成弹簧甚至整个从动盘减振结构断裂，使用寿命短；液力扭转减振器效果较好，但成本太高。
发明内容
为提高混合动力系统中发动机与电机连接可靠性，提供了一种用于混合动力车的扭转减振器。这种减振器传递扭矩并卸载冲击，重量轻，转动惯量小，安装空间小，结构简单可靠，成本低。
实现本发明目的的技术方案是：
一种用于混合动力车的扭转减振器，包括从动盘，还包括从动盘的摩擦片上由下到上依次叠置的摩擦盘、碟簧和盖，盖将碟簧和摩擦盘罩住，盖的外圈设有安装孔，内圈边设有卡爪，摩擦盘内圈设有卡槽，卡槽与卡爪适配。
卡爪为至少2个。
摩擦盘外圆尺寸大于或等于摩擦片外圆尺寸。
摩擦盘的中心位置与从动盘的中心位置叠装。
安装孔为至少2个。
当发动机或电机输出扭矩较小时，通过压缩减振弹簧即可传递所需扭矩，此时减振弹簧工作在低应力区间，减振器不会发生破坏；当发动机或电机输出扭矩较大或变化过快，减振器无法通过压缩减振弹簧及时传递足够的扭矩，则从动盘开始打滑，通过摩擦片与摩擦盘和飞轮的滑磨传递扭矩，因为碟簧在安装状态下压紧力是固定的，而摩擦片的摩擦系数会随温度的变化而变化，但在正常工作温度内，摩擦系数基本稳定，所以滑磨扭矩相对固定。由于打滑，将原本作用于减振弹簧、减振盘、支承板等零件上的冲击部分转化成摩擦做功，卸载了扭矩冲击，从而保护电机轴和从动盘不受冲击损坏。
这种减振器传递扭矩并卸载冲击，重量轻，转动惯量小，安装空间小，结构简单可靠，成本低。
附图说明
图1为实施例的结构示意图；
图2为图1的A-A处剖面图；
图3为实施例的安装结构图。
具体实施方式
下面结合实施例和附图对本发明的内容作进一步的阐述，但不是对本发明的限定。
实施例：
如图1-3所示，一种用于混合动力车的扭转减振器，包括从动盘4，还包括从动盘4的摩擦片4-1上由下到上依次叠置的摩擦盘3、碟簧2和盖1，盖1将碟簧2和摩擦盘3罩住，盖1的外圈设有安装孔1-1，内圈边设有卡爪1-2，摩擦盘3内圈上设有卡槽3-1，卡槽3-1与卡爪1-2适配。
卡爪1-2为至少2个。
摩擦盘3外圆尺寸大于或等于摩擦片4-1外圆尺寸。
摩擦盘3的中心位置与从动盘4的中心位置叠装。
安装孔1-1为至少2个。
将减振器安装在飞轮上，当发动机或电机输出扭矩较小时，通过压缩减振弹簧4-6即可传递所需扭矩，此时减振弹簧4-6工作在低应力区间，减振器不会发生破坏；当发动机或电机输出扭矩较大或变化过快，减振器无法通过压缩减振弹簧4-6及时传递足够的扭矩，则从动盘4开始打滑，通过摩擦片4-1、摩擦盘3和飞轮的滑磨传递扭矩，因为碟簧2在安装状态下压紧力是固定的，而摩擦片4-1的摩擦系数会随温度的变化而变化，但在正常工作温度内，摩擦系数基本稳定，所以滑磨扭矩相对固定，由于打滑，原本将作用于减振弹簧4-6、减振盘4-3、支承板4-4等零件上的冲击被部分转移到打滑上，通过摩擦卸载了扭矩冲击，从而保护电机轴和从动盘4不受冲击损坏。
当发动机与电机正常运转，其输出扭矩小于最大扭矩且波动较小，此时减振器通过压缩减振弹簧4-6即可传递所需扭矩，不会发生滑磨。当车辆急加速和急减速时减振器会通过滑磨卸载扭矩冲击。
不同车型所需的减振器不同，可通过改变各部件的外形尺寸及调节碟簧2的工作压紧力，以调节减振器的最大传递扭矩。
