Abstract
The utility model relates to a shock-absorbing front fork base for a bicycle, which has two straight pipes and bridge connection part, wherein, two ends of the bridge connection part are connected with the upper sections of the straight pipes together in an integrating molding way; the bridge connection part internally has an empty room; therefore, the shock-absorbing front fork base has the advantages of high structure strength, long service life, and the like, and is especially suitable for off-road vehicles or mountain climbing vehicles.
Description
Technical field
The utility model is relevant with bicycle, is meant a kind of shock-proof front-fork assembly base of bicycle especially, has high structural strength, and long service life is particularly suitable for cross-country car or mountain-climbing car.
Background technology
The shock-proof front-fork assembly that generally is used for bicycle includes puts on the shelf and a base, and this is put on the shelf and has a vertical tube, and a shoulder is covered on this vertical tube bottom, and two breeches pipes are extended downwards by these shoulder lid two ends; This base then has two straight tubes to be planted wherein for these two breeches pipes of putting on the shelf, and a bridging part connects this two straight tube; Front-wheel is established in order to connect in this straight tube bottom, in this straight tube and be equipped with fluid and/or spring, in order to the shock-absorbing effect to be provided.
The base of existing shock-proof front-fork assembly is respectively after the moulding, to utilize glue to bind in two straight tubes and bridging part again, and after the long-term use, the glue layer between straight tube and bridging part easily produces the slit because of fatigue or deterioration, even causes straight tube and bridging part disconnected from each other.
The utility model content
A purpose of the present utility model is to provide a kind of shock-proof front-fork assembly base of bicycle, has high structural strength.
Another purpose of the present utility model is to provide a kind of shock-proof front-fork assembly base of bicycle, its long service life.
Take off purpose for before reaching, the shock-proof front-fork assembly base of bicycle provided by the utility model includes two straight tubes and a bridging part, wherein, this bridging part is that the epimere with its two end and described straight tube links together in integrated mode, in this bridging part and had a chamber.
Wherein has a foaming heartwood in the empty chamber of this bridging part.
Wherein this two straight tube and this bridging part system is made by fibre reinforced resin.
Wherein this straight tube has a large-diameter portion and a minor diameter part, and this large-diameter portion is the epimere that is positioned at this straight tube.
The beneficial effects of the utility model are: a kind of shock-proof front-fork assembly base of bicycle is provided, has high structural strength.Provide a kind of shock-proof front-fork assembly base of bicycle, its long service life.

10 shock-proof front-fork assembly bases
20 straight tubes, 21 epimeres
22 large-diameter portions, 24 minor diameter parts
30 bridging parts empty chambers 32
34 foaming heartwoods
The utility model specifies representative graph to be: Fig. 5.
The specific embodiment
In order more to understand characteristics of the present utility model place, lift with next preferred embodiment now and cooperate graphic being described as follows, wherein:
See also the front elevation of Fig. 1 the utility model one preferred embodiment; The top view of Fig. 2 the utility model one preferred embodiment; The lateral plan of Fig. 3 the utility model one preferred embodiment; Fig. 4 is the cutaway view of Fig. 1 along the 4-4 direction, the shock-proof front-fork assembly base 10 that the utility model one preferred embodiment is provided is to be made by the carbon fiber reinforcement resin, fiber can adopt but be not limited to carbon fiber, glass fibre, boron fiber or Ke Weila (Kevlar) fiber, resin can be thermosetting resin or thermoplastic base resin, and this shock-proof front-fork assembly base 10 includes two straight tubes 20 and a bridging part 30.
This straight tube 20 has a large-diameter portion 22 and a minor diameter part 24, and this large-diameter portion 22 is the epimeres 21 that are positioned at this straight tube 20, uses for an oil sealing (figure do not show) ccontainingly, and 24 of this minor diameter parts can be planted for a breeches pipe of putting (figure does not show) on the shelf.
This bridging part 30 is that the epimere 21 with its two end and described straight tube 20 links together in integrated mode, has had chamber 32 in this bridging part 30, has a foaming heartwood 34 in this room 32.
During actual the manufacturing, this two straight tube 20 is first hardened formings, then, form the blank of bridging part 30 with the fiber weaving cloth looping of pre-soaked resin in the epimere 21 of two straight tubes 20, in this bridging part 30 and be coated with a foaming heartwood 34, insert in the lump again to heat in the mould (figure does not show) and make the hardening of resin moulding, this foaming heartwood 34 makes expanded by heating fiber weaving cloth to paste the inwall that is butted on mould simultaneously, so this bridging part 30 can link together with this two straight tube 20, and there is not the gap fully between this bridging part 30 and this two straight tube 20, as Fig. 5 is that Fig. 1 is along shown in the cutaway view of 5-5 direction, its structure is firm, structural strength is high, can bear high strength stress and long service life, is specially adapted to cross-country car or mountain-climbing car.
Based on spirit of the present utility model, the structure of this shock-proof front-fork assembly base 10 can be changed, for example: also can not establish foaming heartwood 34 in this bridging part 30, change with other liquid or solid material that can be transformed into gas that is heated and also can, the large-diameter portion 22 of this two straight tube 20 also can be according to need and not if change shape with minor diameter part 24, such as these easy full of beard and structural change, all should be the utility model claim and contain.
