Abstract
The utility model discloses an air resistance buffering front shock absorber which comprises a barrel, an upper base seat, a base, a dust cap, a seal ring, an air bag and a spring, wherein the upper base seat is arranged at the top of the barrel, the base is arranged at the bottom of the barrel, a cylindrical convex column is fixedly connected to the upper base seat and the base, the dust cap and the seal ring are sequentially arranged at the top of the barrel along the inside of the barrel, the air bag is fixed around the cylindrical convex column on the base in the barrel, one end of the spring is clamped on the convex column on the upper base seat in the barrel, and the other end of the spring is clamped on the convex column on the base in the barrel. The air resistance buffering front shock absorber provided by the utility model is used for solving the problems that the parts and the components are miscellaneous and the cost of the buffer material is high, has the advantages of strong practicability, low cost, good shock absorption effect and the like; and the production cost of the enterprise is effectively reduced, .
Description
Technical field
The utility model belongs to front fork vibration damper technical field, more specifically relates to a kind of vapour lock vibration damper that is used on electric bicycle and the battery-operated motor cycle front fork.
Background technique
Along with the infiltration of green low-carbon theory, the development of new material and new technology in addition, electric motor car progresses into the development climax as zero delivery green traffic instrument.At present, the front fork of electric bicycle and battery-operated motor cycle mostly adopts hydra-shock absorber, its inner accuracy of manufacturing height, and complex structure, and its hydraulic pressure material adopts oil more, this just makes the cost of traditional hydraulic damper increase greatly; Traditional shock absorber reduces damping effect, even loses damping performance sometimes because of sealing the bad leakage that is very easy to cause hydraulic oil in the vibration damper.
The model utility content
The purpose of this utility model is to provide a kind of cost of production lower, simple in structure, and damping effect is better, and need not to inject the vapour lock buffering front shock absorber of hydraulic oil.
To achieve these goals, the utility model is by the following technical solutions:
A kind of vapour lock buffering front shock absorber, comprise cylindrical shell, top base, base, dust cover, seal ring, air bag and spring, it is characterized in that, described cylindrical shell top is provided with top base, the bottom is provided with base, all be fixedly connected with a cylindrical projection on described top base and the base, described cylindrical shell top is provided with described dust cover and seal ring successively along the cylindrical shell inboard, described air bag is fixed in the cylindrical shell around the cylindrical projection on the described base, described spring one end is arranged on the projection of described top base in the cylindrical shell, and the other end is arranged on the projection of base in the described cylindrical shell.
Preferably, be fixed with a cylindrical projection on the base in the described cylindrical shell, described projection middle part is provided with the thread groove of indent, and described both ends of the spring is arranged on the thread groove.
Preferably, described top base is stressed salable in the cylindrical shell top when moving downward.
Preferably, described base is that nylon material is made, and is sealed in the cylindrical shell bottom.
The utility model advantage compared to existing technology is: inner barrel simple in structure, and cost of production reduces greatly; Described cylindrical shell top is provided with top base, the bottom is provided with base, top base is stressed salable in the cylindrical shell top when moving downward, base is sealed in the cylindrical shell bottom, so just can not be because of sealing the bad damping effect variation that causes, the cylindrical shell top is provided with dust cover and seal ring along the cylindrical shell inboard, makes the better tightness of this equipment, strengthens damping effect; Both ends of the spring is arranged in respectively on the projection of interior top base of cylindrical shell and base, and projection is provided with the thread groove of indent, makes its steadiness splendid; And this equipment is to reach dual damping effect by the air bag on the base in spring and the cylindrical shell, and its travelling comfort is good, and increase working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, cylindrical shell; 2, top base; 3, base; 4, dust cover;
5, seal ring; 6, air bag; 7, spring; 8, projection.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is made further description explanation.
A kind of as shown in Figure 1 vapour lock buffering front shock absorber, comprise cylindrical shell 1, top base 2, base 3, dust cover 4, seal ring 5, air bag 6 and spring 7, cylindrical shell 1 top is provided with top base 2, the bottom is provided with base 3, top base 2 is stressed salable in cylindrical shell 1 top when moving downward, base 3 is sealed in cylindrical shell 1 bottom, so just can not be because of sealing the bad damping effect variation that causes, cylindrical shell 1 top is provided with dust cover 4 and seal ring 5 successively along cylindrical shell 1 inboard, it is in order to prevent that dust and other impurities from falling in the cylindrical shell 1 that dust cover 4 is set, influence the damping effect of vibration damper, it is in order to prevent that vibration damper is because of sealing the bad damping effect that reduces that seal ring 5 is set, even forfeiture damping performance, all be fixedly connected with a cylindrical projection 8 on described top base 2 and the base 3, described air bag 6 is fixed in the cylindrical shell 1 around the cylindrical projection 8 on the base 3, these projection 8 middle parts have the indent thread groove, being convenient to spring 7 firmly is fixed on the projection 8, described spring 7 one ends are arranged on the projection 8 of top base 2 in the cylindrical shell 1, and the other end is arranged on the projection 8 of base 3 in the cylindrical shell 1.Base 3 is by the nylon material manufacturing, because its crushing resistance is good, wear resistance is strong, can increase the working life of vibration damper, and with low cost.
Above-described only is optimal way of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these also should be considered as within the protection domain of the present utility model.
