Abstract
The utility model discloses a hydraulic damper used for a bicycle and an electric bicycle. The hydraulic damper comprises an upper supporting base, a lower supporting base and an oil storage cylinder. The upper supporting base and the lower supporting base are provided with installation holes respectively, the oil storage cylinder is filled with oil, one end of the oil storage cylinder is connected with the lower supporting base, the other end of the oil storage cylinder is connected with a locking nut, a piston is arranged in the oil storage cylinder, the piston is provided with a piston rod, the piston rod penetrates through the locking nut to be connected with the upper supporting base, a thread is arranged on the oil storage cylinder, an adjusting nut is arranged at the position of the thread in a sleeved mode, the oil storage cylinder is sleeved with a spring, one end of the spring is connected with the adjusting nut, the other end of the spring is connected with the upper supporting base, and a flow valve and a rebound valve are arranged in the piston. The hydraulic damper has the advantages that damping is achieved through an internal hydraulic structure, even if vibration is larger, the ideal damping effect can be achieved, the service life of the damper can be prolonged, and the replacement cost is reduced.
Description
Technical field
The utility model relates to a kind of for the hydraulic damper on bicycle, electric bicycle.
Background technique
At present, at the bicycle using, the vibration damper on electric bicycle, structure is all fairly simple, often adopts spring to reach damping effect, although, spring also can play damping effect, still, and after after a while, spring just there will be fatigue phenomenon, cause damping effect obviously to decline, need to often change, cost is high.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, thereby provide a kind of long service life and damping effect significantly for the hydraulic damper on bicycle, electric bicycle.
To achieve these goals, designed a kind of for bicycle of the utility model, hydraulic damper on electric bicycle, comprise upper branching holder, lower bearing support and oil storage cylinder, in described upper branching holder and lower bearing support, be respectively equipped with mounting hole, in described oil storage cylinder, be filled with oil, described oil storage cylinder one end is connected with lower bearing support, the other end is connected with lock nut, in described oil storage cylinder, be provided with piston, described piston is provided with piston rod, described piston rod passes lock nut and is connected with upper branching holder, described oil storage cylinder is provided with screw thread, described screw thread place cover has regulating nut, described oil storage cylinder overcoat has spring, described spring one end is connected with regulating nut, the other end is connected with upper branching holder, in described piston, be provided with flowing valve and rebound valve.
Further, in described oil storage cylinder, near lock nut one end cover, there is guide holder, between described guide holder and lock nut, be provided with outside framework oil seal.By guide holder, piston is fixed to effect.
Further, in described lock nut, be provided with anti-dust seal.
Further, between described oil storage cylinder and lower support seat and between piston and oil storage cylinder, be provided with seal ring.
Further, the shell of described upper support seat, lower support seat, oil storage cylinder and piston rod is aluminum alloy.
With the bolt of vehicle frame, through mounting hole, be fixed on vehicle frame, when compression stroke, the piston in vibration damper moves down, and the oil pressure in oil storage cylinder raises, and fluid is flowed through flowing valve in piston upper chamber, has produced damping force when compression movement.When extension stroke, piston moves up, and the oil pressure in epicoele raises, and flowing valve is closed, and fluid is pushed rebound valve open and flowed in oil storage cylinder.In compression stroke and extension stroke, all can produce damping force, reach the requirement of rapid damping.
What the utility model obtained is a kind of for the hydraulic damper on bicycle, electric bicycle, its technique effect is: by inner hydraulic structure, carry out damping, even if vibrations are larger, also can reach desirable damping effect, and can extend working life of vibration damper, reduce replacement cost.
