one deck rubber pipe, technology is like this, helical spring sprays one deck elastomer latex as spraying paint, prior art is feasible, can also be helical spring dipping elastomer latex, helical spring can give heat once slightly, the helical spring sulfuration good spray or dipping is good, helical spring garden post outer round surface, surface, interior garden is pasted and is added the flexible rubber skin of one deck, inside and outside garden post surface elasticity rubber skin has been unified sulfuration with spring steel bar outer layer rubber leather block, above-mentioned being combined in the mould carried out, rubber material claims the flat spin both ends of the spring, in order to connect with stressed two ends, the two ends mold pressing has fixed connection apparatus, according to quiet section or design needs, in mould, give pressure of helical spring, example: a helical spring free height is 40 centimetres, the compression height is 20 lis in mould, the rubber mold pressing claims the flat spin both ends of the spring in mould, and the sticking flexible rubber skin of one deck is pasted in post outer garden in helical spring garden, behind the molded vulcanization, helical spring free height is 25 centimetres, and the constraint that helical spring has been subjected to elastic caoutchouc has a flexible pulling force.Use on a certain vehicle, the helical spring height is 20 centimetres of compression strokes in the time of quiet section, and the rubber skin is stressed to be 0, and the extension stroke lower dead center uphold to arrive 20 centimetres of equilibrium positions just from small to large an elastic pulling force up the time, and damping is upheld.Spongy rubber is installed in the helical spring, in the equilibrium position 20 centimetres the time, spongy rubber is stressed to be 0, and compression stroke just has cushion effect from small to large, extension stroke, elastic force is from big to small just arranged, equilibrium position elastic force is zero, and it is big more that rubber suitcase helical spring and spongy rubber spring have a general character to leave the equilibrium position big more reverse elastic force pulling force of distance, and the equilibrium position is near more, power is more little, and they are opposite each other.As quiet section helical spring of vehicle is 22 lis high, the spongy rubber spring is that down 2 centimetres of springs are softer in 20 centimetres of high equilibrium positions, same principle vibration damping, so just can design comparatively ideal quiet winding degree as required, with moving winding degree, mould is to stabilization, the front and back stabilization, a kind of four-wheel car the right and left of example is parked on a slope, existing helical spring runs into this road surface, because of the body sway center of gravity all over moving 16 centimetres of low 20 centimetres of boil down tos in spring balancing position, one side, 20 centimetres of extensions of high one side spring are 24 centimetres, when the equilibrium position has all been departed from both sides 20 centimetres, suspension elastic element of the present invention, low one side foam spring stress, the flexible rubber pulling force in high one side has certain transverse stabilization function.Stabilization before and after two front-wheels and two trailing wheels in like manner have has certain antidive effect.This suspension elastic element is made garden column piece (1) by the spongy rubber of above-mentioned multi-level different hardness density and is installed in the helical spring (2), slide-and-guide post (3) passes from the post center hole of spongy rubber garden, one is connected and fixed vehicle body, one is passed and can slide up and down from rotating incorgruous post (4) center hole, rotating directional post guarantees to connect reliable by the same supporting base of bearing (5) (6) Joining clasp (7), supporting base (6) connects the helical spring fixing device by screw (8), and the helical spring fixing device is connected and fixed vehicle body by screw (9).
The present invention compared with prior art has following advantage:
This suspension elastic element, the vibration isolation sound insulation is easy to maintenance, compact structure, have the life-span long, because of not needing the vibration damper cost low, have certain lateral stability longitudinal stability effect, obtain comparatively ideal quiet winding degree easily, move winding degree.
