Description
Technical field
The utility model belongs to technical field of automobile parts, relates to a kind of compound vehicle bracket of shock absorber.
Background technique
Automobile is very universal, becomes the traffic tool indispensable in life.Along with growth in the living standard, people have higher requirement to the travelling comfort of car steering.When automobile travels on road, if run into the road surface of jolting, generally by the shock-absorbing spring, carry out the vibrations on absorbing and filtering road surface, but the shock-absorbing spring himself also has to-and-fro motion after compressed, and the concussion of vibration damper while being used to just to suppress bounce-back after the spring shock-absorbing and from the impact on road surface, to improve the smoothness of automobile running.
Vibration damper is arranged on automobile suspension system inside, the one end connects vehicle body, the other end connecting vehicle frame, the structure of vibration damper is generally in the piston rod insertion cylinder with piston, be full of oil in cylinder, throttle orifice is arranged on piston, make the oil in two-part space separated by piston to complement each other.
As Chinese practical new patent application (201020625491.6) discloses a kind of front shock absorber of automobile, mainly comprise holder assembly, rubber pad, front coil spring, bumper and vibration damper on dust cover, interior union, damping pad, plain washer, spring washer, nut, bolt, external connecting sleeve, end ring, bearing, helical spring: vibration damper comprises piston rod, work cylinder barrel, piston, rebound valve, oil storage cylinder barrel, compression valve, recuperation valve, flowing valve, guide holder, dust-proof cover, oil sealing; Be provided with interior union in described dust cover, interior union peripheral hardware has damping pad, be provided with bolt on external connecting sleeve, be provided with successively plain washer, spring washer and nut in interior union, be provided with successively holder assembly, rubber pad and front coil spring on end ring, bearing, helical spring at damping pad one end, this vibration damper can improve the intensity of vibration damping assembly and not reduce travelling comfort.But the heat that the piston of this vibration damper and cylinder barrel wall friction produce can't distribute by the cylinder arm timely, and heat dispersion is poor.
For above-mentioned heat dissipation problem, vibration damper adopts double-barrel structure at present, and vibration damper has inside and outside two cylinders, piston moves in inner core, due to the entering and extracting out of piston rod, in inner core, the volume of oil increases and contraction thereupon, therefore will be by with urceolus, exchange to maintain balance oily in inner core.But the heat that the piston of this kind of vibration damper and internal barrel wall friction produce can't distribute by the cylinder arm timely, another kind of vibration damper has appearred for this reason, this vibration damper is the individual layer Cylinder wall structure, piston rod is the hollow structure that insertion end is opening, be fixed with a compression valve in the opening end end of piston rod, hollow structure by piston rod replaces the shoe cream room that double-barrel structure forms, thereby makes piston contact and can directly dissipation of heat be gone out with barrel, reduces oil liquid temperature.But due to the vibration damper of this kind of structure, when piston moves downward, fluid can only move upward under pressure, and the fluid in the cylinder barrel bottom remains static, and can't flow fully, makes the damping property variation, anti-distortion ability reduces.
