Abstract
The utility model discloses an air pressure type shockproof front fork for the bicycle. A tube body at one end of the axle center of the bicycle shockproof front fork is connected with a front fork bushing, a dust proof sleeve, axle center buffer rubber, an outer tube cover and a DU bearing are arranged in the tube body in the axle center, the tube body at the other end in the axle center is threaded in the outer tube by combining with a sliding bearing, to ensure that an outer cover arranged in the axle center is jointed with one end of the outer, and an air faucet is arranged on the outer tube cover; an air-blocking plug is arranged in the outer tube, and a sealing air chamber is formed between the end of the axle center positioned in the outer tube and the air-blocking plug. Since the sealing air chamber is arranged, the shockproof effect can be attained by charging through the air faucet, and the setting load can be adjusted in time through the air faucet. The rigid return spring of the traditional shockproof vertical tube is replaced, and the utility model has the advantages that the weight is light, the appearance is novel, and the front fork can be charged, etc.
Description
Technical field
The utility model relates to a kind of shock-proof front-fork assembly of bicycle, refers in particular to a kind of automatic shock-proof front fork of vapour-pressure type.
Background technology
At present, the front fork of bicycle generally comprises front fork and engages with the shock-absorbing standpipe.Play the shock-absorbing effect and be in the shock-absorbing standpipe with MCU or retracing spring as shake avoiding body, thereby reach shock-proof effect.Though the Front fork vibration abatement standpipe of said structure can reach the shock-absorbing purpose, weight is heavier, and profile is bigger and not attractive in appearance.
Summary of the invention
The purpose of this utility model is to provide a kind of vapour-pressure type shock-proof front-fork assembly, and it reaches shock-proof effect by the air chamber that forms in vertical tube of front fork, has in light weight, advantages such as outward appearance is novel, inflatable adjustment precompressed load.
In order to achieve the above object, the utility model is realized by following technical scheme.
A kind of vapour-pressure type shock-proof front-fork assembly, mainly form by front fork sleeve pipe, axle center, valve, axle center cushion compound, dust protecting cap, outer tube lid, DU bearing, plain bearing, outer tube, retaining vent plug, it is characterized in that: an end body in axle center connects the front fork sleeve pipe, on the body in axle center, be provided with dust protecting cap, axle center cushion compound, outer tube lid, DU bearing, the other end body in axle center is located in the outer tube in conjunction with plain bearing, make the outer tube lid that is located on the axle center close, cover at outer tube valve is set with outer tube one termination; In outer tube, also be provided with the retaining vent plug, place the axle center end in the outer tube and keep off sealed air chamber of formation between the vent plug.
Adopted the utility model with the shock-proof front-fork assembly of air as shake avoiding body, can reach shock-proof effect by valve inflation formation air chamber owing to be provided with a sealed air chamber, valve can in time be adjusted the precompressed load.The rigidity retracing spring that has replaced traditional shock-absorbing standpipe, have in light weight, outward appearance is novel, advantage such as inflatable.The start of the utility model shock-absorbing increases its sliding with the support of DU bearing, and with the spacing control beat of anise, can be assembled on the different front fork pin of diversification.

The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present utility model is further elaborated.
A kind of vapour-pressure type shock-proof front-fork assembly as shown in Figure 1 and Figure 2 mainly is made up of front fork sleeve pipe 1, axle center 2, valve 6, axle center cushion compound 4, dust protecting cap 3, outer tube lid 7, DU bearing 5, plain bearing 11, outer tube 12, retaining vent plug 15.Front fork sleeve pipe 1 is used to be assembled in various front fork pin.The one end body in axle center 2 connects front fork sleeve pipe 1, is provided with dust protecting cap 3, axle center cushion compound 4, outer tube lid 7, DU bearing 5 on the body in axle center 2.Dust protecting cap 3 is located between front fork sleeve pipe 1 and the outer tube lid 7, is used to protect this axes section; Cushion compound 4 forward fork sleeve pipes 1 in axle center also are close to axle center 2; DU bearing 5 places in the outer tube lid 7 in conjunction with X type ring 9 and contacts with axle center 2, and DU bearing 5 can support to increase sliding when the shock-absorbing start, and with the spacing control beat of anise.The other end body in axle center 2 is located in the outer tube 12 in conjunction with plain bearing 11, makes the outer tube lid 7 that is located on the axle center 2 close with outer tube 12 1 terminations.Joint at outer tube lid 7 and outer tube 12 is provided with O type ring 8; In the axle center 2 with outer tube 12 inwall joints also be provided with O type ring 10.On outer tube lid 7 valve 6 is set, the inflation inlet of valve 6 exposes outside outward to manage and covers 7, adjusts the precompressed load by valve 6 inflations.Also be provided with retaining vent plug 15 in outer tube 12, retaining vent plug 15 is provided with O type ring 13 with outer tube 12 inwall junctions, and retaining vent plug 15 utilizes 14 lockings of two hexagon socket countersunk flat cap head screws.Place axle center 2 ends in the outer tube 12 and keep off sealed air chamber of formation between the vent plug 15.
