摘要：【中文】本发明实施例公开了一种洗衣机减震器，涉及洗衣机技术领域，包括外管、上盖、摩擦环和活塞杆，外管设有连通的第一腔室和第二腔室，第一腔室位于外管的端部，上盖设置于第一腔室，上盖设有通孔和安装槽，摩擦环设置于安装槽内，摩擦环的两端设有波浪形端面，活塞杆的一端穿过上盖和摩擦环后插设于第二腔室，且活塞杆的杆身与摩擦环紧密贴合。在换向过程中，摩擦环的波浪形端面发生弹性形变，摩擦环先随着活塞杆一同移动，然后摩擦环再与活塞杆相对移动，活塞杆受到摩擦环的静摩擦力从0增加至动摩擦力，活塞杆受到的换向冲击减小，进而震动和噪音也相应的减小。 【EN】The embodiment of the invention discloses a washing machine shock absorber, which relates to the technical field of washing machines and comprises an outer tube, an upper cover, a friction ring and a piston rod, wherein the outer tube is provided with a first cavity and a second cavity which are communicated, the first cavity is positioned at the end part of the outer tube, the upper cover is arranged in the first cavity, the upper cover is provided with a through hole and an installation groove, the friction ring is arranged in the installation groove, the two ends of the friction ring are provided with wavy end faces, one end of the piston rod penetrates through the upper cover and the friction ring and then is inserted into the second cavity, and a rod body of the piston rod is tightly attached. In the reversing process, the wavy end face of the friction ring is elastically deformed, the friction ring moves along with the piston rod, then the friction ring moves relative to the piston rod, the static friction force of the piston rod on the friction ring is increased from 0 to the dynamic friction force, the reversing impact on the piston rod is reduced, and further the vibration and the noise are correspondingly reduced.
