Embodiment
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present invention and effect easily.
In order to can the present invention be described in detail, first, inversion type front damping device for motorcycle of the present invention is illustrated:
As shown in Figure 1 to Figure 2, for the structural representation of the embodiment of the present invention, the invention provides a kind of inversion type front damping device for motorcycle, comprise sleeve 1, one end of described sleeve is fixed on end cap 2, the other end is set in outside breeches pipe 3, is formed be slidably matched with breeches pipe, and the described breeches pipe the other end is connected in end cylinder 4; Described end cap 2 central position connects connecting rod 5, and connecting rod 5 one end is connected with the piston body 7 of damper clutch release slave cylinder 6 li through guide holder; One end of described connecting rod 5 assembles valve seat 8, spring sheet 9, valve block 10 and piston body 7 successively, and is fixed by self-locking nut 11; Described damper clutch release slave cylinder 6 the other end is connected with the integrated type plug 12 on end cylinder 4; The 3 stops multidiameter shaft that described integrated type plug 12 increases successively for diameter, described damper clutch release slave cylinder 6 is socketed in first paragraph axle 14 outer wall; Described breeches pipe 3 is socketed in second segment axle 15 outer wall, and cylinder of the described end 4 is socketed in the 3rd section of axle 16 outer wall; Ensure that damper clutch release slave cylinder 6 and breeches pipe 3 moment keep coaxial relation.
Wherein, center, described integrated type plug 12 upper-end surface is provided with bolt hole, is connected with the lower end bottom valve body of described damper clutch release slave cylinder 6 by bolt.Ensure piston and integrated type plug stable connection, axis and radial deflection can not be produced.
Wherein, center, described integrated type plug 12 lower end surface is provided with bolt hole, is bolted on cylinder of the described end 4.Ensure integrated type plug 12 and end cylinder 4 stable connection, axis and radial deflection can not be produced.
As shown in Figure 3, be the structural representation of integrated type plug in the embodiment of the present invention.
Wherein, the outer side surface of described integrated type plug first paragraph axle 14 is provided with the first annular groove 17.A non-removable entirety is formed with after damper clutch release slave cylinder 6 roll extrusion.Ensure that damper clutch release slave cylinder operationally can not produce axis and radial deflection, rock.
Wherein, the arranged outside of described integrated type plug second segment axle 15 has outside thread, is directly connected with described breeches pipe 3 internal thread.This Placement, can make the connection of integrated type plug and breeches pipe more firm.
Wherein, the arranged outside of described integrated type plug second segment axle 15 has peripheral groove 18, is provided with oil seal ring in groove.Prevent damping oil from revealing.
Wherein, described piston body 7 cylindrical is provided with the second annular groove 19, is provided with piston ring 20 in described second annular groove 19.
Wherein, described piston ring 20 adopts polyoxymethylene to make.Tradition front shock absorber piston ring adopts teflon, and cost is very high.The present invention adopts polyoxymethylene to substitute the material that teflon does piston ring, and do not affect the using effect of vibration damper after change, polyoxymethylene makes simple, and wear-resistance and oil-resistance again, can meet the needs in front shock absorber driving process completely, and reduce cost.
Working principle of the present invention is: vibration damper valve seat 8, spring sheet 9, valve block 10, piston body 7 are assemblied on connecting rod 5 and are tightened by self-locking nut 11, can play reliable anti-loose effect, and operating item is convenient simultaneously, and efficiency is high.Because integrated type plug 12 is the different concentric cylinder of three sections of radiuses, the damper clutch release slave cylinder 6 be socketed on first paragraph axle 14 outer wall can be ensured, the end cylinder 4 being socketed in the breeches pipe 3 on second segment axle 15 outer wall and being socketed on the 3rd section of axle 16 outer wall, under any circumstance all coaxial; When motorcycle is in rough road traveling, when vibration damper constantly pumps, damping spring 21 is also thereupon constantly reciprocating, now damping spring 21 constantly imports or derives damper clutch release slave cylinder, because integrated type plug 12 ensure that the coaxality of damper clutch release slave cylinder 6 and breeches pipe 3 well, namely ensure that the coaxality of damper clutch release slave cylinder 6 and breeches pipe 3 endoporus, can not impact damper clutch release slave cylinder 6 and produce metal strike sound when damping spring 21 imports damper clutch release slave cylinder, thus avoid vibration damper generation abnormal sound.
