Abstract
The utility model relates to a double-spring damper, which comprises a direction column, an upper connecting plate, a lower connecting plate, damping rods, first straight springs, damping cylinders and second straight springs, wherein the two ends of the upper connecting plate and the lower connecting plate are respectively, symmetrically and fixedly connected with the two damping cylinders in a penetrating way, the direction column is connected with the middle parts of the upper connecting plate and the lower connecting plate, the upper end of each damping cylinder is connected with the upper connecting plate through bolts, an inner cavity of each damping cylinder is provided with a guide rod, the bottom end of each damping cylinder is connected with each damping rod through each first straight spring and each second straight spring which are sheathed on each damping rod, each damping rod is correspondingly matched with each guide rod and does reciprocating movement in each damping cylinder along each guide rod, and the lower end of each damping rod is provided with a hinging hole. The double-spring damper has the advantages that the shockproof and damping performances are good, the service life is long, and the safety performance is good.
Description
Technical field
The utility model relates to a kind of vibration damper, relates in particular to a kind of motor tricycle dual spring vibration damper.
Background technique
Along with motorcycle technology development, the travelling comfort that motorcycle is driven, the requirement of Security are more and more higher.At present, most of motorcycles have all disposed forward and backward vibration damper, to reduce vibrations that Uneven road causes to motorcycle and driver and passenger's influence.The motorcycle vibration absorber of prior art adopts the preceding damping of the straight-tube of two-wheeled motorcycle mostly, also be that the upper end of decoupling rod is fixedly mounted in the mounting hole of joining plate up and down, the lower end of decoupling rod is plugged at the bottom of the damping in the tube, be provided with damping spring in the decoupling rod, be provided with damping oil in damper cylinder and the decoupling rod, be provided with seal ring and oil sealing between the upper end of damper cylinder and the decoupling rod, the mode that adopts inner spring to combine with hydraulic damping, vibration energy in absorption and the consumption motorcycle driving process is to reduce vibrations to motorcycle and driver and passenger's influence.Syndeton length between existing vibration damper and the vehicle frame is short, the external diameter of decoupling rod is little, be easy to generate in the running process and tremble shake, influence Security and travelling comfort that motorcycle is driven, and impact resistance is poor, flexible distortion produces security incident, and the spacing between symmetrically arranged decoupling rod is less, and the enforcement space is less in the unloading process.
Summary of the invention
In order to overcome many defectives that vibration damper in the prior art exists, the purpose of this utility model provides that a kind of shock resistance, damping performance are good, long service life, motor tricycle dual spring vibration damper that Safety performance is high.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of dual spring vibration damper, it is characterized in that comprising the direction post, last joining plate, second line of a couplet fishplate bar, decoupling rod, the first straight spring, damper cylinder and the second straight spring, last joining plate and second line of a couplet fishplate bar two ends are symmetrical fixedly cross-under two damper cylinders all, the direction post is connected in joining plate and second line of a couplet fishplate bar neutral position, the damper cylinder upper end is connected on the joining plate by bolt, the damper cylinder inner chamber is provided with guide rod, the bottom of damper cylinder is connected decoupling rod through being socketed on the straight spring of first on the decoupling rod with the second straight spring elasticity, decoupling rod and guide rod corresponding matching are along guide rod and move back and forth in damper cylinder, and the decoupling rod lower end is provided with hinging hole.
The diameter of described decoupling rod is 50-70mm, preferred 55-65mm.
The centre distance of described two damper cylinders or two damper cylinders is 220-300mm, preferred 240-280mm.
Described guide rod and damper cylinder articulating point to the distance of decoupling rod upper end greater than 800mm, preferred 800-950mm.
After adopting above technological scheme, the beneficial effect that the utility model reaches is: guide rod and damper cylinder articulating point to the distance of decoupling rod upper end greater than 800mm, be not easy in the running process to produce and tremble shake, strengthened and vehicle frame between linking intensity, that improves the driver can be handling; The diameter of decoupling rod is 50-70mm, and preferred 55-65mm has improved the impact resistance of vibration damper, is difficult for taking place because of the crooked security incident that causes of decoupling rod; The centre distance of two damper cylinders or two damper cylinders is 220-300mm, preferred 240-280mm, strengthened the distance between two decoupling rods, make things convenient for the exchange of front and back wheels, improved the bearing capacity of motor tricycle simultaneously, after the hinging hole assembling locking of wheel axle and two damper cylinders, make whole vibration damper form a firm rectangular tank bracket, impact resistance is strong.The utility model vibration damper has effectively improved the damping of front damper of motorcycle, and the travelling comfort of motorcycle driving and Security.
