The adjustable damper comprises an outer cylinder, an oil seal, a top valve, an inner cylinder, a piston rod, a piston valve, a bottom valve, a connecting ring, a damping valve seat, a damping valve body, a damping return spring, a damping valve element, a sealing ring and a control unit. The piston rod divides the inner cylinder into an upper working cavity and a lower working cavity; a gap between the inner cylinder and the outer cylinder is an oil storage cavity, and an additional cavity is arranged on the outer side of the inner cylinder; the damping valve body is provided with a center hole, a damping adjusting hole and an adjusting cavity, the center hole is communicated with the connecting ring and the adjusting cavity, and the damping adjusting hole is communicated with the adjusting cavity and the oil storage cavity. The adjustable damper not only has the damping effect of an existing damper, but also can adjust the damping change amplitude in real time according to the actual needs of a user, the damping adjustment range of the adjustable damper is larger than the damping range of the existing damper, and the application range of the damper is wider due to the unique totally-closed design principle of the adjustable damper.
本发明公开了一种可调阻尼器,所述可调阻尼器包括外筒、油封、顶阀、内筒、活塞杆、活塞阀、底阀、连接环、阻尼阀座、阻尼阀体、阻尼回位弹簧、阻尼阀芯、密封圈、控制单元;所述活塞杆将所述内筒分为上工作腔和下工作腔;所述内筒与所述外筒之间空隙为储油腔,所述内筒外侧设有附加腔室;所述阻尼阀体设置中心孔、阻尼调节孔、调节腔室,所述中心孔连通所述连接环和所述调节腔室,所述阻尼调节孔连通所述调节腔室和所述储油腔。该可调阻尼器不仅拥有现有阻尼器的阻尼效果,还可以根据用户实际需要,对阻尼变化幅度进行实时调节,其阻尼调节范围也比现有阻尼器阻尼范围更大,其独特的全封闭设计原理,也导致该阻尼器应用范围更加广泛。
