以下结合附图1-4对本发明作进一步详细说明。
本发明实施例提供一种阻尼连续可调减振器。参照图1，阻尼连续可调减振器包括缸体总成和电磁阀总成7，缸体总成包括储油缸1、工作缸2、中间缸3、复原阀4、压缩阀5、活塞杆6、以及油封导向总成；中间缸3与工作缸2固定连接；工作缸2上设有通孔21，连通工作缸2和中间缸3；活塞杆6与复原阀4固定连接；油封导向总固定在工作缸2的顶部。
参照图2和图3，电磁阀总成7包括外壳71、阀体72、阀座75、阀盘76、电磁组件79，电磁组件79包括线圈791、衔铁792和极靴底座793，外壳71的一端固设于储油缸1的侧壁，电磁组件79设置于外壳内远离储油缸1的端部。外壳71上设有与中间缸3连通的进油口711和与储油缸1连通的出油口712；电磁阀总成7位于阀体72内设有可沿外壳71轴向移动的阀芯杆73，阀体72的顶端均匀设有四个与进油口711和出油口712连通呈弧形的阻尼调节孔721，阀体72的顶端设有与旋转阀片74，旋转阀片74的叶片数量设置有四个并与阻尼调节孔721一一对应，阀芯杆73在移动过程中可驱动旋转阀片74转动用于调节阻尼调节孔721油液流通面积。
参照图3和图4，阀芯杆73上沿自身长度方向螺旋设有弧形凹槽731，旋转阀片74的端部设有与弧形凹槽731配合使用的球形凸起741。在普通道路行驶的情况下，电磁线圈791通小电流，衔铁792在磁力作用下带动磁阀芯杆73位移，阀芯杆73的弧形凹槽731将位移行程转换成旋转运动，旋转阀片74开始旋转，阀体72底部阻尼调节孔721流通面积逐渐增大，通过阀体72上较小的阻尼调节孔721和减振器本身的减振特性实现减振的功。在道路良好的情况下，线圈791通上较大电流，此时电磁阀芯杆73的位移行程达到最大，旋转阀片74的旋转角度也达到最大，阀体72底部的阻尼调节孔721流通面积达到最大，四个弧形阻尼调节孔721全部打开，此时电磁阀油液流通面积最大，减振器的阻尼力最小，汽车的舒适性和稳定性会提高。
参照图2，阀体72内设有用于使阀芯杆73复位的复位组件78，复位组件78包括复位弹簧781和弹簧底座782，弹簧底座782固设于阀体72的端部，复位弹簧781设置于弹簧底座782上，另一端与阀芯杆73的端部连接。当阀芯杆73移动时会使复位弹簧781处于拉伸状态，当电流逐渐减小时，复位弹簧781会使阀芯杆73向原始位置移动，电流消失后阀芯杆73移动至原始位置，完成复位。
参照图2和图3，同时为了限制旋转阀片74转动形成，在阀体72的端部设置有限位挡片722，限位挡片722设置有四个，并分别设置于每个阻尼调节孔721的一侧，且限位挡片722的高度高于旋转阀片74，旋转阀片74转动过程中会抵触到限位挡片722，限制转动角度的最大值，在初始状态，阀芯杆73没有位移行程，此时旋转阀片74的旋转角度为0度，此时阻尼调节孔721流通面积最小，随着电流的逐渐增大，阀芯杆73的位移增加，旋转阀片74的旋转角度不断增大，当旋转角度达到15度时，此时阀体阻尼调节孔721流通面积达到最大。
参照图2和图3，为了避免旋转阀片74转动过程中在阀芯杆73上移动的情况出现，阀体72位于限位挡片722上设有用于防止旋转阀片74沿阀芯杆73移动的挡片723，阀芯杆73穿过挡片723，挡片723能够将旋转阀片74限位在阀体72上，避免旋转阀片74移动的情况出现。
参照图2和图3，阀座75设置于外壳71进油口711的位置并与阀体72连接，进油口711贯穿阀座75，阀座75上设有阀盘76，阀盘76上设有用于使自身复位的主弹簧77，主弹簧77的另一端设置于阀体72上，阀盘76的底部设有多个与进油口711连通的进油孔761，阀座75与阀盘76形成上油腔，阀盘76与阀体72之间形成下油腔；阀体72的周侧均匀设有若干泄压小孔724，泄压小孔724与出油口712连通。当电磁阀断电或电磁阀失效的时候，油液从进油口711不断流入，上油腔的油液压力过大时，油液能够推动阀盘76移动，使主弹簧77压缩，油液从阀体72壁上的泄压小孔724流到外壳71，最终从外壳71的出油口712流出到储油缸1，达到泄压和断电保护作用。泄压后，当上油腔和下油腔油液压差不大时，主弹簧77将阀盘76复位至初始状态。
该种阻尼连续可调减振器的实施原理如下：在普通道路行驶的情况下，线圈791通小电流，衔铁792在磁力作用下带动磁阀芯杆73位移，阀芯杆73的弧形凹槽731将位移行程转换成旋转运动，旋转阀片74开始旋转，阀体72底部阻尼调节孔721流通面积逐渐增大，通过阀体72上较小的阻尼调节孔721和减振器本身的减振特性实现减振的功能。在道路良好的情况下，线圈791通上较大电流，此时电磁阀芯杆73的位移行程达到最大，旋转阀片74的旋转角度也达到最大，阻尼调节孔721流通面积达到最大，四个弧形阻尼调节孔721全部打开，此时电磁阀油液流通面积最大，减振器的阻尼力最小，汽车的舒适性和稳定性会提高。在路况不平整或者路况糟糕的情况时，线圈791断电，电磁阀的复位弹簧781使阀芯杆73复位至初始状态，此时所有的阻尼调节孔721都关闭，油液流通面积最小，减振器阻尼力最大，满足汽车在糟糕路况情况下的减振需求。当电磁阀断电或电磁阀失效的时候，油液从进油口711不断流入，上油腔的油液压力过大时，油液能够推动阀盘76移动，油液从阀体72壁上的泄压小孔724流到外壳71，最终从外壳71的出油口712流出到储油缸1，达到泄压和断电保护作用。泄压后，当上油腔和下油腔油液压差不大时，主弹簧77将阀盘76复位至初始状态。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
