Description

一种电控阻尼减震器
技术领域
本发明涉及减震器领域,具体涉及一种电控阻尼减震器。
背景技术
传统的液压式可调减震器就是通过增减液压油的方式调整高度升降及阻尼大小,因为要增减液压油数量,整套系统比较复杂,成本高,对于生产工艺要求也高。以国内目前的生产水平,很难自主生产及大范围推广。
发明内容
本发明的目的在于:提供一种结构简单的电控阻尼减震器。
本发明是通过以下技术方案实现的:一种电控阻尼减震器,包括减震筒,所述减震筒的两端密封,所述减震筒内通过气液隔板分隔为气体仓与液体仓,所述气液隔板与减震筒内壁密封活动连接;所述液体仓内设有活塞,所述活塞上设有活塞杆,所述活塞杆沿减震筒轴向伸出减震筒,所述活塞与活塞杆均为金属材质,所述活塞上设有通孔,所述活塞杆端部设有线缆接头;所述液体仓内充满液压油,所述液压油内均匀分散有磁性微粒;所述气体仓内充有高压气体。
作为本发明的进一步优选方案,所述气液隔板上设有定位弹簧,所述定位弹簧位于气体仓内,所述定位弹簧的轴线与减震筒的轴线平行。
与现有技术相比,本发明具有以下有益效果:
本发明的减震器,通过电流控制阻尼的大小,结构简单,适于大范围推广。
附图说明
图1是本发明的结构示意图;
图2是活塞结构示意图。
具体实施方式
下面结合附图,对本发明作详细的说明。
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
如图1及图2所示一种电控阻尼减震器,包括减震筒1,所述减震筒1的两端密封,所述减震筒1内通过气液隔板2分隔为气体仓3与液体仓4,所述气液隔板2与减震筒1内壁密封活动连接;所述液体仓4内设有活塞5,所述活塞5上设有活塞杆6,所述活塞杆6沿减震筒1轴向伸出减震筒1,所述活塞5与活塞杆6均为金属材质,所述活塞5上设有通孔51,所述活塞杆6端部设有线缆接头61;所述液体仓4内充满液压油,所述液压油内均匀分散有磁性微粒;所述气体仓3内充有高压气体。所述气液隔板2上设有定位弹簧7,所述定位弹簧7位于气体仓3内,所述定位弹簧7的轴线与减震筒1的轴线平行。
在汽车或者摩托车或其他使用该减震器的交通/生产工具上,设置震动感应器,震动感应器与线缆接头61有效电连接,震动感应器将感应到的震动信号转为电信号,从而控制接通到活塞5的电流大小。活塞5接通电流,实现对减震器阻尼大小的调控。具体调控方式有两种:
(一)通过控制活塞5结构实现对阻尼大小的调控。根据接通到活塞5的电流大小,调控活塞孔打开和关闭的数量,调节流通活塞孔油液的流量,实现对减震器阻尼大小的调控;
(二)通过附着在活塞孔上的磁性微粒的磁力大小实现对阻尼大小的调控。活塞5接通电流触发磁力产生装置,液压油内的磁性微粒便会朝活塞5聚集,磁性微粒附着在活塞5及活塞孔51等孔中,通过接通的电流大小的不同,磁性微粒的附着力的强弱不同,调节流通活塞孔油液的流量,实现对减震器阻尼大小的调控。
当然,可以通过手动控制电流大小,以实现调节阻尼的效果。
气液隔板2在减震器工作的过程中会上下运动,定位弹簧7保证了气液隔板2的位置不偏移。
气体仓3内充有高压气体,使液体仓4内的液压油始终处于高压状态,从而使得液压油在工作过程中产生的气泡数量减少,大小减小。气泡的数量及大小减小,使得液压油通过活塞5的通孔51时速度均匀,避免间歇性的无阻力状态,保证了稳定性。
