Description

联动式新能源车刹车卡钳 技术领域
本实用新型属于制动器技术领域，涉及一种刹车卡钳，特别涉及联动式新能源车刹车卡钳。
 背景技术
刹车卡钳属于碟式刹车是由一个与车轮相连的刹车圆盘和圆盘边缘的刹车钳组成，刹车时通过刹车油推动制动块使之夹紧刹车盘从而产生制动效果，现有技术中，为了增加制动性能通常将制动蹄片延长增大与刹车圆盘的摩擦面积，但是容易出现以下问题，制动蹄片过长会由于受力不平衡导致磨损不均，造成性能不够稳定且下降过快。
 技术问题
本实用新型的目的是针对现有技术中存在的上述问题，提供了一种分体式蹄片联动运行，独立活塞控制，不易发生相互影响使得制动效果更好的刹车卡钳。
 技术解决方案
本实用新型的目的可通过下列技术方案来实现：联动式新能源车刹车卡钳，包括壳体、端盖、制动蹄片和联动蹄片，所述的壳体和端盖相互配合成型用于安装制动蹄片和联动蹄片，其特征在于，所述制动蹄片的长度大于联动蹄片的长度，所述的制动蹄片通过并列设置的第一活塞和第二活塞推动，所述的第一活塞和第二活塞内部相互连通，所述的联动蹄片通过第三活塞推动，所述的第三活塞为独立设置与第一活塞第二活塞相互隔离，所述的壳体上具有与第一活塞第二活塞配合的制动软管接口和放气嘴一，所述的壳体上具有与第三活塞配合的联动软管接口和放气嘴二。
在上述的联动式新能源车刹车卡钳中，所述的壳体与端盖之间设置有若干与制动蹄片、联动蹄片配合的导向杆和弹片。
在上述的联动式新能源车刹车卡钳中，所述的壳体上固定有便于其安装的支架。
在上述的联动式新能源车刹车卡钳中，所述的壳体与端盖之间通过三个内六角螺钉相互紧固。
在上述的联动式新能源车刹车卡钳中，所述的壳体上设置有滑动轴，所述的滑动轴外部套设有胶套且端部与制动泵连接。
本联动式新能源车刹车卡钳将常规的前后联合制动的一副蹄片改为两副独立工作的蹄片（制动蹄片和联动蹄片），即使存在因前后制动的使用频率不同，引起蹄片的不均匀磨损，也不相互受影响。
常规的刹车卡钳，由于其结构形式与使用非前后联合制动的卡钳完全不同，所以安装支架均需重新开模，这样不仅延长了开发周期，也增加了开发成本，本实用新型所使用的支架与非前后联合制动所用的支架保持不变，无需重新开模，缩短了开发周期，降低了开发成本。
常规的刹车卡钳为三活塞整体式，既要考虑到三个活塞的分布，又要考虑钳口要承受三个活塞同时工作输出的液压强度，所以卡钳不仅高度高，而且体积大，本实用新型由壳体、端盖通过三个内六角螺钉联接而成，用三个内六角螺钉来承受液压，大大降低了钳口高度，体积也随之缩小。
本实用新型设置有三个活塞两副蹄片，其中两个相邻的第一活塞和第二活塞通过制动软管接口连通前制动管路，第三活塞通过联动软管接口连通后制动管路，他们自成体系，各自针对独立的蹄片工作，互不干涉。
 有益效果
与现有技术相比，本联动式新能源车刹车卡钳主要通过将蹄片设计成两个且相互独立，各自通过独立的活塞控制，具有性能更加稳定且制动效果更好的优点。

 本发明的最佳实施方式
以下是本实用新型的具体实施例并结合附图，对本实用新型的技术方案作进一步的描述，但本实用新型并不限于这些实施例。
如图1至图5所示，本联动式新能源车刹车卡钳，包括壳体1、端盖2、制动蹄片3和联动蹄片4，壳体1和端盖2相互配合成型用于安装制动蹄片3和联动蹄片4，制动蹄片3的长度大于联动蹄片4的长度，制动蹄片3通过并列设置的第一活塞5和第二活塞6推动，第一活塞5和第二活塞6内部相互连通，联动蹄片4通过第三活塞7推动，第三活塞7为独立设置与第一活塞5第二活塞6相互隔离，壳体1上具有与第一活塞5第二活塞6配合的制动软管接口8和放气嘴一9，壳体1上具有与第三活塞7配合的联动软管接口10和放气嘴二11。
本联动式新能源车刹车卡钳通过阀门将传统的液压管道一分为二，一路通过制动软管接口8与第一活塞5和第二活塞6连通，另一路通过联动软管接口10与第三活塞7连通，使蹄片独立工作互不干涉。
进一步说明，壳体1与端盖2之间设置有若干与制动蹄片3、联动蹄片4配合的导向杆12和弹片13，导向杆12用于对蹄片的活动轨迹进行限位使其与活塞运行方向相同，弹片13用于在制动力消失后将蹄片复位。
壳体1上固定有便于其安装的支架14，本刹车卡钳通过支架14安装于机动车的减震器上。
壳体1与端盖2之间通过三个内六角螺钉15相互紧固，用三个内六角螺钉15来承受液压，大大降低了钳口高度，体积也随之缩小。
壳体1上设置有滑动轴16，滑动轴16外部套设有胶套17且端部与制动泵连接，胶套17主要起到防尘的作用，滑动轴16用于调节被动侧蹄片的磨损，即蹄片是两边相互夹紧制动盘实现刹车，一侧蹄片磨损后可以通过活塞调节间隙，由于活塞只和其中一侧蹄片接触因此增加滑动轴16用于调节另一侧的间隙。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本实用新型的本质；把它们解释成任何一种附加的限制都是与本实用新型精神相违背的。
