The invention relates to an automobile seat part, in particular to a rubber spring mechanical suspension. The rubber spring mechanical suspension comprises an upper support frame and a lower support frame. The upper support frame and the lower support frame are connected by a revolving bracket. The rubber spring mechanical suspension is characterized in that moving shafts are fixed to the front parts of the upper and lower ends of the revolving bracket; chutes are formed in the two inner sides of the upper support frame and the lower support frame; the two moving shafts are movably embedded in the chutes; a rubber block is fixed to the top end of the upper moving shaft; revolving shafts are fixed to the back parts of the upper and lower ends of the revolving bracket; the upper and lower revolving shafts are installed in shaft holes in the upper support frame and the lower support frame movably; cylinder rubber is sleeved on the upper and lower revolving shafts. The rubber spring mechanical suspension has the advantages that 1, the rubber block, serving as a rubber spring, has high nonlinearity, thus a rigid adjusting mechanism does not need to be provided, so the structure is simple, and manufacturing cost is low; 2, the rubber spring has a small size, thereby being suitable for being arranged inside the limited space of a suspension seat and capable of meeting the requirement for fatigue life.
