Abstract
A Yu An double DU liner bushing front shock damper applicable for an autobicycle has the structural characteristics that an inner end DU liner bushing 12, an opening locating collar 9, an outer end DU liner bushing 8 and an liner bushing retaining ring 7 are arranged in a deep hole inside a bottom cylinder 10 to form a bottom cylinder combination. A damping vibration spring 3, a Y-type pipe 11, a packing ring 13, a cushioning spring 14 and a piston pipe 15 form a Y-type pipe combination which is arranged inside the bottom cylinder combination to form a movable fitting working surface of the Y-type pipe 11 and the outer end DU liner bushing 8 in and the inner end DU liner bushing 12 inside the deep hole inside the bottom cylinder 10, thereby achieving the purpose of reducing motion frictional resistance and processing difficulty of the deep hole inside the bottom cylinder 10, leading damping performance to be more stable, and simultaneously keeping amenity of the shock damper on different roads with different loads.
Description
One, technical field:
The utility model relates to a kind of bumper, especially is suitable for the two DU lining front shock absorbers of Chongqing peace on the motor bike.
Two, background technology:
The end cartridge type front shock absorber of domestic production at present is conventional single DU lining front shock absorber, and this front shock absorber mainly is made up of plug, O type circle, damping spring, cover of dust, oil seal collar, oil sealing, outer end lining, end tube, breeches pipe, piston ring, buffer spring, piston tube, tightening seal washer, screw etc.; Its architectural feature is: in end cartridge type front shock absorber, outer end has only a DU lining in the end tube, this structure requires high to end tube processing technology, to the endoporus of processing end tube, particularly during deep hole, the straightness accuracy of its endoporus, garden degree, shape, dimensional accuracy, roughness of surface require high, cause the friction force instability between the surface of deep hole and breeches pipe outside face running-fit, undesirable in the end tube, make tube of the final end and breeches pipe running-fit poor, cause the front shock absorber traveling comfort poor.
Three, summary of the invention:
The purpose of this utility model provides the two DU lining front shock absorbers of a kind of Chongqing peace, be two DU lining front shock absorbers by changing single DU lining front shock absorber, solved at the bottom of the front shock absorber the high and quality control difficulty of deep hole working technological requirement in the tube, motion friction fit power is big, the problem of comfort difference.
Concrete scheme of the present utility model is: mainly comprise plug, O type circle, damping spring, cover of dust, oil seal collar, oil sealing, lining back-up ring, outer end DU lining, opening locating bush, end tube, breeches pipe, inner DU lining, piston ring, buffer spring, piston tube, tightening seal washer, screw composition.Its structural feature is: be made of the breeches pipe combination damping spring, breeches pipe, piston ring, buffer spring, piston tube, constitute end tube combination by end tube, lining back-up ring, outer end DU lining, opening locating bush, inner DU lining, breeches pipe is made up in the end tube combination of packing into, tube lower end, end piston tube, tightening seal washer, screw are connected and fixed, inject damping oil after oil sealing, oil seal collar, cover of dust pack into from the breeches pipe outer end again, seal with O type circle, plug last breeches pipe outer end.Adopt two DU linings to support the breeches pipe running-fit in end tube deep hole, the inner DU lining of end tube deep hole and outer end DU lining Wai Yuan and end tube endoporus interference fit contact with the breeches pipe surface with smooth inside and outside end DU lining bore area, as the driving surface of running-fit.
Adopt such scheme, tube interior surface of deep hole in the end is not re-used as the driving surface with the breeches pipe running-fit, so just reduce technology and quality control difficulty in the deep hole working in the end tube, reduce the friction coefficient when the tube combination is with its running-fit driving surface relative motion of breeches pipe at the bottom of the front shock absorber simultaneously, reduce the friction of motion resistance, make damping capacity more stable, improve the traveling comfort that front shock absorber uses.
Four, description of drawings:
Fig. 1 is an integral structure scheme drawing of the present utility model, also is a kind of embodiment of the present utility model.
Fig. 2 is the local enlarged diagram of architectural feature among Fig. 1.
Five, the specific embodiment:
As shown in Figure 1: the utility model mainly comprises by plug 1, O type circle 2, damping spring 3, cover of dust 4, oil seal collar 5, oil sealing 6, lining back-up ring 7, outer end DU lining 8, opening locating bush 9, end tube 10, breeches pipe 11, inner DU lining 12, piston ring 13, buffer spring 14, piston tube 15, tightening seal washer 16, screw 17 and forming.Can know in conjunction with Fig. 2 and to find out that architectural feature of the present utility model is: in by end tube 10 garden interference fit outside deep hole and the inner DU lining 12, put into opening locating bush 9, constitute end tube with the outer garden interference fit of outer end DU lining 8 and make up; The breeches pipe combination that constitutes by plug 1, O type circle 2, damping spring 3, breeches pipe 11, piston ring 13, buffer spring 14, piston tube 15 again; Breeches pipe is made up in the end tube combination of packing into, and piston tube 15 1 ends in the breeches pipe combination and tightening seal washer 16, screw 17 are connected and fixed with end tube 10.Form the outer end DU lining 8 and the inner DU lining 12 inside face running-fits of deep holes in breeches pipe 11 and the end tube 10, form piston ring 13 running-fits on breeches pipe 11 interior surface of deep hole and the piston tube 15.
Also can see from Fig. 1:
Opening locating bush 9 is to be resilient sleeve, and compression diameter is packed into and opened automatically behind the deep holes in the end tube 10, with 7 combined actions of lining back-up ring under guarantee not end float misalignment in end tube 10 deep holes of two DU linings.
The utility model is work like this: end tube 10 is under the effect of external force, drive fastening piston tube 15 upper piston rings 15 of screw 17 to Fig. 1 left to motion, damping hole produces resistance to compression pression on the piston tube 15 to force in the breeches pipe 11 the clutch release slave cylinder damping oils to be flowed through, and this moment, damping spring 3 was compressed; When damping spring 3 was replied original length, effort made end tube 10 to the right operation on piston tube 15, made the damping oil of its end tube 10 interior clutch release slave cylinders enter in the breeches pipe 10 interior clutch release slave cylinders by the resistance hole on the piston tube 15, produced and restored resistance.In whole crank motion process, breeches pipe 11 axial running-fit usable lengths are by piston tube 15 and piston ring 13 location, breeches pipe 11 is axial, garden surface alignment in running-fit inner end DU lining 12 and the outer end DU lining 8 radially, the surface, interior garden and the driving surface of surface, breeches pipe 11 outer garden of inner DU lining 12 and outer end DU lining 8 as running-fit, the interior surface of deep hole of thoroughly having isolated end tube 10, and the surface, outer garden and end tube 10 endoporus interference fit of inner DU lining 12 and outer end DU lining 8, static relatively, inner DU lining 12 is that smooth plastic-blasting surface contacts the friction coefficient when reducing running-fit with breeches pipe 11 surfaces with outer end DU lining 8 endoporus.
