Description

一种车用离合器 技术领域
本申请涉及一种车用离合器。
背景技术
传统双离合器自动变速器，其单一离合器承受动力源所有扭矩。比如电机峰值扭矩为200牛米，则单一离合器承载能力则为200牛米。现在也有一些将两个离合器进行锁定的方式，但是其锁定的结构可靠性较差，且操控较为不便，实用性远未达到要求。
现阶段一般是采用锁环式惯性同步器，通过摩擦力把齿圈以及锁环以保持同步，但是该种方式对于车用离合器的复合来讲，操作起来较为不便，在车用离合器的结合以及分离之时都有非常多的不适宜之处。
发明内容
为了解决上述问题，本申请提出了一种车用离合器，包括初级离合器，在初级离合器的另一侧设有第一驱动器和第二驱动器，在初级离合器内设有第一次级离合单元和第二次级离合单元，所述第一驱动器与第一次级离合单元动力相连，所述第二驱动器与第二次级离合单元动力相连；所述第一次级离合单元包括第一次级离合器和与第一次级离合器配合设置的摩擦单元，所述第二次级离合单元包括第二次级离合器和与第二次级离合器配合设置的摩擦单元，在第一次级离合器和第二次级离合器之间还设有一同步器，所述同步器设置成第一次级离合器以及第二次级离合器分离时，所述同步器将第一次级离合器与 第二次级离合器锁止为一个整体。本申请通过设置两次级离合单元，使得可以根据不同的工况选择是采用单一离合器承受，还是两个离合器共同承受，在使用时，一般是利用一个次级离合器承受额定扭矩，在峰值扭矩的状态下，则通过同步器将两个离合器进行锁止，从而更好的承载峰值扭矩，且采用离合器进行锁止之后，两离合器的之间的同步性更好，增强其承载峰值扭矩的可靠性。

优选的，还包括离合器压紧板，所述离合器压紧板与第一次级离合单元或第二次级离合单元抵接设置，在离合器压紧板与初级离合器之间设有压紧弹簧。

如图中所示，为了更清楚的阐释本申请的整体构思，下面结合说明书附图以示例的方式进行详细说明。
另外，在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非 另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接，还可以是通信；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。
在第一个实施例中，如图1所示，一种车用离合器，包括初级离合器1，在初级离合器1的另一侧设有第一驱动器2和第二驱动器3，在初级离合器1内设有第一次级离合单元和第二次级离合单元，第一驱动器2与第一次级离合单元动力相连，第二驱动器3与第二次级离合单元动力相连；第一次级离合单元包括第一次级离合器4和与第一 次级离合器4配合设置的摩擦单元5，第二次级离合单元包括第二次级离合器6和与第二次级离合器6配合设置的摩擦单元5，在第一次级离合器4和第二次级离合器6之间还设有一同步器7，同步器7设置成第一次级离合器4以及第二次级离合器6分离时，同步器7将第一次级离合器4与第二次级离合器6锁止为一个整体。
使用时，手动或者自动触发第一驱动器2和/或第二驱动器3，第一驱动器2带动第二次级离合单元，第二驱动器3带动第二次级离合单元，在满足指定条件下，同步器7将两次级离合器进行锁止或者结合，的指定条件可以是扭矩到达一定值之后，通过电控的方式控制同步器7动作将二者结合，也可以是同时触发第一驱动器2和第二驱动器3之后，二者在机械结构的作用下通过同步器7完成锁止。此处所说的同步器7是指的可以将第一次级离合器4以及第二次级离合器6进行同步的原件，可以是普通的机械同步器7也可以是电子形式的同步器7，只要可以满足第一次级离合器4以及第二次级离合器6完成同步即可。
在第二个实施中，如图2所示，摩擦单元5包括与第一次级离合器4或第二次级离合器6相连的离合器摩擦片8以及与初级离合器1固连的钢片9。第一次级离合器4包括与离合器摩擦片8相连的第一竖板10，第一竖板10通过第一横板11与第一连接板12相连；第二次级离合器6包括与离合器摩擦片8相连的第二竖板13，第二竖板13通过第二横板14与第二连接板15相连；第一连接板12上设有第一卡接环16，第二连接板15上设有第二卡接环17，同步器7设在第 一卡接环16、第二卡接环17的一侧；同步器7包括一同步环18，同步环18的侧部设有一归位环19，归位环19通过一弹性件20与第一横板11和/或第二横板14抵接设置；第一卡接环16，第二卡接环17以及同步器7相邻抵接设置；弹性件20设在归位环19以及第二横板14之间；弹性件20为弹簧；第二连接板15上设有一侧接环21，侧接环21与第二卡接环17相连；同步器7上设有花键，第一卡接环16以及第二卡接环17上设有与花键卡接设置的卡接键；卡接键上设有斜向设置的锥面齿。第一驱动器2包括第一分离杠杆22，第一分离杠杆22与第一分离轴承23配合设置，第一分离轴承23与第一连接杆24相连，第一连接杆24穿过初级离合器1与第一次级离合器4相连。第一连接杆24包括与第一分离轴承23相连的第一横向分离杆25，第一横向分离杆25与一沿第一横向分离杆25运动方向延伸的第一竖向分离杆26相连，第一竖向分离杆26与第一传动分离杆27相连，第一传动分离杆27穿过初级离合器1设置，第一传动分离杆27与第一次级离合器4相连。第一竖向分离杆26嵌入到初级离合器1内。第二驱动器3包括第二分离杠杆28，第二分离杠杆28与第二分离轴承29配合设置，第二分离轴承29与第二连接杆30相连，第二连接杆30穿过初级离合器1与第二次级离合器6相连。第二连接杆30包括与第二分离轴承29相连的第二横向分离杆31，第二横向分离杆31与一沿第二横向分离杆31运动方向延伸的第二竖向分离杆32相连，第二竖向分离杆32与第二传动分离杆33相连，第二传动分离杆33穿过初级离合器1设置，第二传动分离杆33与第二次级离合器 6相连。第二竖向分离杆32嵌入到初级离合器1内。还包括离合器压紧板34，离合器压紧板34与第一次级离合单元或第二次级离合单元抵接设置，在离合器压紧板34与初级离合器1之间设有压紧弹簧35。
该实施例是选择的在第一个实施例的基础上，一种纯机械的实施方式。具体的联动方式，第一次级离合单元的部分与第二次级离合单元的部分基本相同。因此，仅以第一次级离合单元说明联动方式，其他与第一个实施例相同。第一驱动器2带动第一连接杆24动作，第一连接杆24带动钢片9完成脱离，然后第一竖板10动作，第一竖板10带动第一横板11动作，第一横板11带动第一连接板12动作，随后完成摩擦部分的结合或者脱离。至于结合器部分，则是首先是第二竖板13上的摩擦片与钢片完成脱离，然后第二横板14带动第二卡接环17动作，随之是第一竖板上的摩擦片与钢片完成脱离，然后第一横板带动第一卡接环16动作，由于第一卡接环16以及第二卡接环17此时同时脱离，同步器7进入第一卡接环16以及第二卡接环17完成卡接锁止作业。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领 域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
