The front shock absorber comprises a shock absorber body and a spring, the shock absorber body comprises a lower fork and a piston rod inserted into the lower fork from an opening in the upper end of the lower fork, a damping column is arranged at one end of the piston rod, and the damping column is connected with the cavity bottom of the lower fork; the other end of the piston rod extends to the position above the lower fork and is fixedly provided with a sleeve shaft, the upper portion of the sleeve shaft is sleeved with a locking nut in a threaded mode, the upper portion of the peripheral side face of the lower fork is fixedly sleeved with a sleeve, a shaft seat is fixedly arranged on the sleeve, and the central axis of a shaft hole in the shaft seat is perpendicular to the central axis of the sleeve. The lower fork and the piston rod are fixedly sleeved with a lower top cover and an upper top cover respectively, and the spring is fixedly arranged between the lower top cover and the upper top cover and arranged on the lower fork and the piston rod in a sleeving mode. According to the shock absorber, the two shock absorber bodies are connected through the connecting rod to form an integrated frame, after the shock absorber is connected with an agricultural vehicle, the situation that the weight applied to a front axle by the whole vehicle is eliminated, the front axle is slightly bent, and the two lower forks are in an unparallel splayed shape can be avoided, so that the shock absorption effect is better, and the shock absorption sensitivity is higher.

    本发明公开了一种机动电动三轮车前减振器,包括减振器本体和弹簧,减振器本体包括下叉和从下叉上端开口插入至下叉内的活塞杆,活塞杆的一端设置有阻尼柱,阻尼柱与下叉的腔底相连;活塞杆的另一端延伸至下叉的上方并固设有套轴,套轴的上部螺纹套设有锁紧螺母,下叉的外周侧面上部固定套设有套筒,套筒上固设有轴座,轴座上轴孔的中轴线与套筒的中轴线垂直;下叉上和活塞杆上分别固定套设有下顶盖和上顶盖,弹簧固设于下顶盖和上顶盖之间,且套设于下叉和活塞杆。本发明通过连杆连接两个减振器本体,形成一体式框架,在与农用车相连后,可以消除整车施加给前轴重量后,前轴微量弯曲使两下叉出现不平行的八字,使得减振效果更好,减振灵敏度更高。
