The invention discloses a balance valve and an automobile shock absorber using the balance valve, and the balance valve comprises a piston assembly which comprises a cylinder body and a lead screw suitable for doing linear motion in the cylinder body; a valve element suitable for synchronously moving along with the lead screw is arranged on the lead screw. The motor assembly comprises a motor shell fixedly connected with the cylinder body, a stator set and a rotor set, wherein the stator set and the rotor set are arranged in the motor shell. Wherein the motor shell comprises a shell body and an end cover which is in sealing fit with one side end, facing the piston assembly, of the shell body, and the interior of the shell body is divided into a stator section for accommodating the stator group and a rotor section for accommodating the rotor group, which are isolated from each other; the rotor group comprises a rotor shell which is in sealing fit with the end cover and a rotor shaft which is in running fit with an inner cavity of the rotor shell; the rotor shaft is provided with a matching cavity suitable for insertion of the lead screw and provided with an internal thread structure; and the screw rod penetrates through the end cover and then extends into the matching cavity so as to realize threaded connection between the rotor shaft and the screw rod. The service life of the whole balance valve can be prolonged.

    本发明公开了一种平衡阀及使用其的汽车减震器,包括:活塞组件,其包括缸体和适于在缸体内做直线运动的丝杆;丝杆上设置有适于随着丝杆同步运动的阀芯;电机组件,其包括与缸体固连的电机壳体和设于电机壳体内的定子组和转子组;其中电机壳体包括壳本体和与壳本体朝向活塞组件的一侧端密封配接的端盖,且在壳本体内分隔形成有相隔绝的用于容纳定子组的定子区间和用于容纳转子组的转子区间;以及转子组包括与端盖密封配接的转子外壳和与转子外壳的内腔转动配合的转子轴;转子轴具有适于丝杆插入的且具有内螺纹结构的配合腔;丝杆贯穿端盖后伸入至配合腔中以实现转子轴与丝杆的螺纹连接。本发明可以延长整体平衡阀的使用寿命。
