The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; This creation aims to provide a kind of bicycle front fork that especially is fit to be applied in; To keep the original controllable function that turns to of bicycle; Even can make front fork combine the restraint device that turns to of shock-proof effect, its integral body turns to restraint device to consist essentially of: an outer tube 10, a central siphon 20, and plural first liner 30; Wherein: this outer tube 10 supplies to be connected with the handle of bicycle, and the predetermined segment internal face of this outer tube 10 is provided with the complex trace first rotation limited section 11; When implementing, each first rotation limited section 11 can be for extending axially the tangent plane of configuration along this outer tube 10; This central siphon 20 is arranged in this outer tube 10 inside relatively, supplies to be connected with the front fork of bicycle, and this central siphon 20 is provided with complex trace relative to the section outer wall that stretches into this outer tube 10 in it and first rotates the 11 cooresponding second rotation limited sections 21, limited section respectively with each; When implementing, each second rotation limited section 21 can be for extending axially the tangent plane of configuration along this central siphon 20; As for, each first liner 30 supplies to serve as a contrast respectively to be located between the cooresponding first rotation limited section 11 and the second rotation limited section 21; When implementing,, each first liner, 30 one serves as a contrast the section of being located between the cooresponding first rotation limited section 11 and the second rotation limited section 21 respectively but connecting a plurality of confessions; And; Each first liner 30 can with this outer tube 10 and this central siphon 20 displacement to axial; And by cooperatively interact (as shown in Figure 4) of each first liner and the first rotation limited section 11 and the second rotation limited section 21; Limit this outer tube 10 and relatively rotate, and then be able to the purpose that turns to the hand shift front fork by bicycle with this central siphon 20.
Basically; This creation turn to restraint device; The main first rotation limited section 11 and 21 designs of the second rotation limited section that see through between outer tube 10 and the central siphon 20 can limit outer tube 10 and rotate relatively with central siphon 20, are able to the purpose that turns to the hand shift front fork by bicycle; Especially, the restraint device that turns to of this creation utilizes first liner 30 to dwindle the contact gap (gap between the first rotation limited section 11 and the second rotation limited section 21) of 20 of outer tube 10 and central siphons, obtains comparatively stable, failure-free and turns to restriction effect.
Moreover; This creation turn to restraint device more can further in this central siphon 20, be equipped with one limit this central siphon 20 and these outer tube 10 slide relative strokes guide pillar 40; And between this guide pillar 40 and this central siphon 20, be provided with one in order to elastic parts 50 to this outer tube 10 and the 20 formation elastic reset effects of this central siphon, make integral body turn to restraint device to combine shock-proof effect with comparatively simple, failure-free design.
When implementing, above-mentioned outer tube 10 is provided with a fixed block 12 in its inwall place with respect to these central siphon 20 tops, and the center of this fixed block 12 is provided with a screw 121, the top of this guide pillar 40 pass this central siphon 20 and with screw 12 bolts of this fixed block 12; The bottom spiral shell of this central siphon 20 is provided with one in order to limit the disk cover 22 that this elastic parts 50 drops; These disk cover 22 centers are provided with a perforation 221; This guide pillar 40 is provided with a support ring 42 near bottom end position, and this guide pillar 40 is provided with the stop section 41 of an external diameter greater than these support ring 42 perforation 421 in its bottom of passing this support ring perforation 421; The position of these elastic parts 50 tops is located in this stop section 41, and with this elastic parts 50 join to; Certainly, among the embodiment that also can be as shown in Figure 3, this stop section 41 further see through a pushing block 43 and this elastic parts 50 join to.
Utilize the said structure design; In the time of can letting this central siphon 20 compress relatively with this outer tube 10; Form buffering, shock-proof effect; And produce the application force that makes central siphon 20 and this outer tube 10 reset, and can guarantee this central siphon 20 and these outer tube 10 firm engagement, avoid this central siphon 20 to get loose and drop with this outer tube 10.
What deserves to be mentioned is that no matter whether the restraint device that turns to of this creation combines shock-proof effect, the external diameter of said central siphon 20 21 sections in the second rotation limited section is relatively greater than the external diameter of its upper section; And; It is good greater than the external diameter of its upper section relatively that this outer tube 10 supplies the external diameter of these central siphon 20 slip sections; Cause is bigger with start object contact surface; The problem that is difficult for commentaries on classics of generation side and beat during start, its stability is better, and can further be provided with the elasticity dust protecting cap 60 that a confession correspondence is connected to this bicycle front fork place in these outer tube 10 bottoms.
Moreover, the turning in the restraint device of this creation shock-proof front-fork assembly, this central siphon 20 is installed with second liner 23 that a plurality of confessions and this outer tube 10 inwalls constitute moving contact in its section place with respect to 21 tops, the second rotation limited section; When implementing, registration mast 231 capable of using is fixed with the mode that knock hole 24 is embedded each other between each second liner 23 and this central siphon 20, makes under the effect of second liner 23, to make this central siphon 20 more firm with the slip of this outer tube 10; And each second rotation limited section 21 of this central siphon 20 can be concave arc shape, and each first liner 30 is provided with a plurality of protuberances 31 in its section place corresponding to the second rotation limited section 21; As for; Each first liner 30 is provided with a plurality of recesses 32 in its section place corresponding to the first rotation limited section 11; Concave, convex portion 32,31 designs of first liner 30 capable of using; Increase the effect that attaches of lubricating oil, make outer tube 10 more smooth and easy, and reduce associated component abrasion speed with the slip of central siphon 20; Certainly, also can be provided with a plurality of recesses, and its section place corresponding to the first rotation limited section is provided with a plurality of protuberances in each first liner, also can reach its identical effect in its section place of each first liner corresponding to the second rotation limited section.
Commonly use structure with tradition and compare, the restraint device that turns to of this creation shock-proof front-fork assembly can utilize first liner to dwindle the contact gap between outer tube and central siphon really, obtain comparatively stable, failure-free turning efficiency, and reduction turns to different sound; In case of necessity, need only change, can effectively prolong the service life that turns to restraint device to worn-down first liner.
Especially, this creation turn to restraint device comparatively simple, failure-free design capable of using, combine shock-proof effect easily; And utilize the concave, convex portion design of first liner; Increase the effect that attaches of lubricating oil, make the slip of outer tube and central siphon more smooth and easy, and reduce associated component abrasion speed.In addition, utilize the design of plural first liner encirclement central siphon, help turning to assembling, the maintenance activity of restraint device.
