Description
Technical field
The utility model relates to a kind of for the hydraulic damper on bicycle, electric bicycle.
Background technique
At present, vibration damper on the bicycle, the electric bicycle that use, 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, the designed one of the utility model is used for bicycle, 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 first piston, described first piston is provided with piston tube, described piston tube is passed lock nut and is connected with upper branching holder, described first piston is provided with piston tube one side and is provided with the second piston, described the second piston is provided with piston rod, described piston rod passes first piston and oil storage cylinder and stretches in lower bearing support, in described piston tube, being provided with spring one end is connected with the second piston, the other end is connected with piston tube upper end, in described first piston, be provided with flowing valve and rebound valve.
Further, described oil storage cylinder is outwardly and one-body molded near lock nut one end, and described oil storage cylinder protrusion place is provided with guide holder, and described guide holder one side is provided with outside framework oil seal.By guide holder, first piston is fixed to effect.
Further, in described lock nut, be provided with anti-dust seal.
Further, between described oil storage cylinder and lower bearing support, between piston tube and upper branching holder, between piston tube and first piston, between first piston and oil storage cylinder and be provided with seal ring between piston rod and first piston.
Further, the shell of described upper branching holder, lower bearing support, oil storage cylinder and piston tube is aluminum alloy.Adopt aluminum alloy, can extend the working life of vibration damper.
Pass mounting hole with the bolt of vehicle frame and be fixed on vehicle frame, in the time of compression stroke, the first piston in vibration damper moves down, the second piston moves up, oil pressure in oil storage cylinder raises, and fluid is flowed through flowing valve in piston tube, has produced damping force in the time of compression movement.In the time of extension stroke, first piston moves up, and the oil pressure in piston tube 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: carry out damping by inner hydraulic structure, even if vibrations are larger, also can reach desirable damping effect, and can extend working life of vibration damper, reduce replacement cost.
