The invention discloses a hydraulic buffer for an automobile. The hydraulic buffer for the automobile comprises a pipe body, a piston, a piston rod, a spring, a bearing, an oil inlet cavity and an oilreturn cavity. The pipe body is internally provided with a damping unit. The damping unit comprises a base fixedly arranged in the pipe body, the base is fixedly provided with a sleeve body, and thesleeve body is internally provided with an extension sleeve in dynamic seal with the piston. A core body is embedded in the sleeve body, and the core body has a degree of freedom of axial movement along the pipe body relative to the sleeve body. By means of the hydraulic buffer for the automobile, the shock absorption effect of the buffer is improved, the impact force generated when the spring moves back and forth is lowered, and the comfort is improved; and meanwhile, through the design of the damping unit structure, flowing of oil is buffered, flowing of the oil is more stable, then the damping stability is improved, and vibration caused by unstable flowing of the oil is lowered.
本发明公开了一种汽车用液力缓冲器,包括管体、活塞、活塞杆、弹簧、轴承、进油腔以及回油腔;所述管体内设置有阻尼单元,所述阻尼单元包括固定在所述管体内的底座,所述底座上固定有套体,所述套体上固定有延伸套,并与所述活塞动密封,所述套体内嵌有芯体,所述芯体相对于所述套体具有沿着所述管体轴向位移的自由度。本发明提高了该缓冲器的减震效果,降低弹簧往返时产生的冲击力,提高舒适性,同时通过阻尼单元结构的设计,对油的流动进行缓冲,使得油的流动更加稳定,进而提高阻尼的稳定性,降低油流动不稳而导致的振动。
