The utility model provides the shock absorber for the bicycle, which has the advantages of simple structure, good stress, no easy breaking, good restoration performance and various shock absorption capacities presetting. The utility model comprises a shock absorption element, a first connecting seat and a second connecting seat. The shock absorption element is an elastic saccule pipe which is provided with a saccule at least. The both ends of the elastic saccule pipe are respectively provided with a bulge loops, and one of the connecting seats is provided with a gas nozzle communicated with the inner cavity of the shock absorption element. The first and the second connecting seats are arranged at the bulge loops positions at the both ends of the shock absorption element, and inner cavity of the shock absorption element is sealed.
Description
The utility model belongs to bicycle assembly parts, particularly a kind of bicycle damper.
Bicycle damper is divided into front shock absorber and rear shock absorber.Wherein front shock absorber places the front fork place.As shown in the figure, rear shock absorber tends to usually crouch and is contained between rear wheel frame and the body framework.The damper element of the forward and backward bumper of commonly using is all coil spring usually, in helical spring axial centre, must be provided with the oil pressure guide rod as axial location and prevent that the moment bullet from stretching.Since rear wheel frame be not along rear shock absorber axially to rear shock absorber extruding, cause often the oil pressure guide rod bending, fracture and the oil hydraulic cylinder leakage of oil was lost efficacy.Therefore, when the rear shock absorber be contained in as crouching with this structure between rear wheel frame and the body framework, be vulnerable to injury most.Install the bicycle of bumper in addition, be commonly the leisure cross-country car that uses on rugged ground, when on uneven ground, travelling, under irregular powerful the collision, the easy oil leakage of the oil hydraulic cylinder of front shock absorber oil pressure guide rod was lost efficacy, the steering handle strenuous vibration of bicycle in causing advancing.In addition, the bicycle weight-saving tends to, and has also limited the specification of this traditional shock absorber, forms the factor that influences strength of parts.
The purpose of this utility model provide a kind of simple in structure, stressed good, not easy fracture, restore the bicycle damper that performance is good, can preestablish various cushioning abilities.
The utility model comprises damper element, first joint seat and second joint seat.Damper element is the elastomeric bladder pipe with retractility; At least be provided with a sacculus on it; Its two ends are respectively equipped with bulge loop; A joint seat is provided with the valve that is communicated with inner chamber; First, second joint seat is installed in bulge loop place, damper element two ends, the inner chamber of sealing damper element.
Wherein:
It also can comprise damper element, last joint seat, following joint seat, arm, arm top cover, damping cylinder and damping cylinder top cover, and damper element is the elastomeric bladder pipe with retractility; At least be provided with a sacculus on it; Its two ends are respectively equipped with bulge loop; Last joint seat center and periphery are respectively equipped with axially extending bore and axial air channel; The arm top cover is provided with valve; The damping cylinder lower end extends engaging lug; Upper and lower joint seat is installed in outside the bulge loop of damper element two ends; Last joint seat engages with the arm lower end; Arm top cover lid is contained in the arm top; Top and bottom ends is placed in the damping cylinder from the damping cylinder top with upper and lower joint seat osed top damper element, the damping cylinder top cover was overlapped the arm lid be contained in the damping cylinder top, following joint seat is locked in the end in the damping cylinder.
Damper element is provided with plural sacculus; The damper element perisporium is the sandwich structure that is embedded with nylon endoplasmic reticular enhancement Layer, strengthens perisporium intensity with netted enhancement Layer.
Plural sacculus has different wall thickness.
Plural sacculus has different external diameters.
Damper element is provided with plural sacculus; And the sheathed ring wall of periphery is provided with the guider ring of axially extending bore between two adjacent sacculus.
The arm free end is provided with communicating pipe.
Because the utility model comprises damper element, first joint seat and second joint seat.Damper element is the elastomeric bladder pipe with retractility; At least be provided with a sacculus on it; Its two ends are respectively equipped with bulge loop; A joint seat is provided with the valve that is communicated with inner chamber; First, second joint seat is installed in bulge loop place, damper element two ends, the inner chamber of sealing damper element.When external force during with axial compression, the sacculus on the damper element then follows radial expansion, and damper element is shortened.When axial force disappeared, sacculus restored, and damper element is by axial extension, reinstatement.Therefore, the telescopicing performance of damper element is given by sacculus.Promptly when being installed in the utility model on the bicycle, sacculus on the damper element reaches the effect of bumper and absorbing shock, not only simple in structure, and stressed good, not easy fracture, to restore performance good, particularly can be with the wall thickness or the external diameter that change the damper element sacculus, preestablish various cushioning abilities, thereby reach the purpose of this utility model.
