The invention belongs to the technical field of bicycles, and relates to a six-connecting-rod damping device and a bicycle frame. The six-connecting-rod damping device comprises a first connecting rod, a second connecting rod, a third connecting rod, a damper body, a lower fork connecting rod and an upper fork connecting rod; the front end of the first connecting rod is rotationally connected with the front triangle, and the rear end is rotationally connected with the upper fork connecting rod; the lower end of the second connecting rod is rotationally connected with the rear upper end of the third connecting rod and the rear end of the shock absorber body; the front end of the third connecting rod is rotationally connected with the front triangle to form a third rotating position, and the rear lower end is rotationally connected with the lower fork connecting rod to form a fourth rotating position; the front end of the shock absorber body is rotationally connected with the front triangle; the upper fork connecting rod is rotationally connected with the rear end of the lower fork connecting rod; the suspension device has the advantages that in the suspension process, the lower fork connecting rod rotates around the fourth rotating position, the fourth rotating position rotates around the third rotating position, the motion trail of the axis of the rear wheel is approximately arc-shaped, the displacement of the suspension device in the horizontal direction is smaller, and the riding gravity center of a rider is more stable.
本发明属于自行车技术领域,涉及一种六连杆减震装置及自行车架,六连杆减震装置包括第一连杆、第二连杆、第三连杆、减震器本体、下叉连杆及上叉连杆;第一连杆的前端与前三角转动连接,后端与上叉连杆转动连接;第二连杆的上端与第一连杆转动连接,下端与第三连杆的后上端及减震器本体的后端转动连接;第三连杆前端与前三角转动连接形成第三转动位,后下端与下叉连杆转动连接形成第四转动位;减震器本体的前端与前三角转动连接;上叉连杆与下叉连杆的后端转动连接;其有益效果是,在避震过程中,下叉连杆围绕第四转动位旋转,第四转动位围绕第三转动位旋转,后轮轴心的运动轨迹近似圆弧形,其在水平方向的位移量更小,骑行者的骑行重心更稳定。
