Description
One, technical field:
The utility model relates to a kind of bumper, especially is applicable to the inversed front shock absorber in middle and high shelves cross-country car and the racing car.
Two, background technology:
At present, the domestic front shock absorber of producing voluntarily is conventional front set absorber, and this bumper mainly is made up of parts such as end tube, front fork tube, piston tube, damping spring and oil sealings.Its architectural feature be front fork tube up, end tube is downward, front fork tube and the upper and lower connecting panel of car load direction post are connected, the resistance hole of this structure is arranged on the piston tube, under the different motion speed condition, the variation of resistance hole is always constant, with the variation of speed, resistance speed is linear fully, and the kinematic pair friction force is bigger.In addition because the mounting means of positively fixed type bumper limits, the bending strength of its breeches pipe a little less than, influence in-use performance because of distortion easily.
Three, summary of the invention:
Problems such as the purpose of this utility model provides a kind of inversed front shock absorber, is the inversion type bumper by changing front set absorber, and it is poor to solve the front shock absorber in-use performance, and the kinematic pair friction force is big, and bending strength is low.
Concrete scheme of the present utility model is: comprise end tube, breeches pipe, damping spring, cover of dust, back-up ring, oil sealing, plain cushion, lining, end cap, screw, its structural feature is: be set with urceolus outside the breeches pipe of the breeches pipe combination that is made of end tube, positioning seat, breeches pipe, in breeches pipe, adorn damping spring, be set with clutch release slave cylinder in the damping spring, one is equipped with the bottom valve combination in the clutch release slave cylinder, connecting rod assembly and guide holder are equipped with in the other end, and connecting rod stretches out the work cylinder end and passes piston tube combination and be threaded with end cap.
Adopt such scheme, increased bending strength, reduced the friction drag of kinematic pair, resistance performance is stable, has improved in-use performance.
Four, description of drawings:
Fig. 1 is an integral structure scheme drawing of the present utility model.
Five, the specific embodiment:
Please see Figure 1, the utility model is mainly by end tube 1, positioning seat 2, breeches pipe 3, damping spring 4, anchor ear 5, clutch release slave cylinder 6, cover of dust 7, back-up ring 8, oil sealing 9, plain cushion 10, lining 11, urceolus 12, outer piston ring 13, open washer 14, jam nut 15, cushion rubber bumper 16, end cap 17, piston tube 18, liner clamp 19, inner carrier ring 20, connecting rod 21, guide holder 22, buffer spring 23, the spacing pad 24 of piston, piston body 25, screw 26, screw 27, spacing pad 28, piston body 29, foot valve seat 30, socket head cap screw 31 is formed, architectural feature of the present utility model is: by end tube 1, positioning seat 2, the breeches pipe 3 outer urceolus 12 that are set with of the breeches pipe combination that breeches pipe 3 constitutes, dress damping spring 4 in breeches pipe 3, be set with clutch release slave cylinder 6 in the damping spring 4, interior one of clutch release slave cylinder 6 is equipped with the bottom valve combination, connecting rod assembly and guide holder 22 are equipped with in the other end, and connecting rod 21 stretches out clutch release slave cylinder 6 ends and passes piston tube combination and be threaded with end cap 17.
Also can see from Fig. 1:
The bottom valve combination is by screw 27 spacing pad 28, piston body 29, foot valve seat 30 to be linked together, and oppositely fixing through socket head cap screw 31.
Connecting rod assembly is made up of connecting rod 21, buffer spring 23, the spacing pad 24 of piston, piston body 25, wherein buffer spring 23, the spacing pad 24 of piston, piston body 25 are sleeved on the connecting rod 21 that stretches in the clutch release slave cylinder 6, one is tightened on the connecting rod 21 by nut 26, and the other end is spacing by guide holder 22.
Bottom valve combination, connecting rod assembly, clutch release slave cylinder 6, guide holder 22 constitute damper.Owing in the breeches pipe combination damper has been installed, therefore, resistance performance is stable.
The piston tube combination is made up of piston tube 18, liner clamp 19 and inner carrier ring 20, and inner carrier ring 20 is installed on the liner clamp 19, and contacts with the inwall of breeches pipe 3; One headgear of piston tube 18 is contained on the liner clamp 19, and the other end is spacing by the open washer 14 that is installed on the connecting rod 21, is provided with nut 15 between open washer 14 and the end cap 17, and cushion rubber bumper 16 is installed in the end cap 17.
One end of damping spring 4 makes up interior positioning seat 2 end faces with breeches pipe and contacts, and the other end contacts with liner clamp 19 end faces of piston tube combination.
Between breeches pipe 3 and urceolus 12, be provided with outer piston ring 13, on breeches pipe 3, have fuel return hole 32, make breeches pipe 3 appearances and urceolus 12 interior table mating surfacess keep oil lubrication at any time, reduced the friction drag of kinematic pair, overcome the bigger shortcoming of conventional positively fixed type kinematic pair friction force.
Two disc brake holes 33 of vertically arranging are arranged on end tube 1, and each 33 next door, disc brake hole is provided with anchor ear 5.Changed the adapter plate design in the high spud angle band disc brake hole of external inversed front shock absorber, reduced installing space, made car load firmly compact more.
The utility model is performed such work: urceolus 12 under external force, on the drivening rod 21 piston body 25 of assembling towards (Fig. 1) lefts to motion.The resistance hole that forces clutch release slave cylinder 6 internal damping oil to be flowed through on the piston body 29 produces resistance to compression pression.At this moment, damping spring 3 is compressed.When damping spring 3 is replied original length, effort on liner clamp 19, on liner clamp 19 drivening rods 21 piston body 25 of assembling to the right motion, make the damping oil of its right-hand member flow through piston body 25 resistance hole and produce the recovery resistance.Damping oil in whole motion process in the breeches pipe 3 is lubricated by 32 pairs of urceolus 12 inside faces of fuel return hole, reduces friction of motion.
Because urceolus 12 is connected with the upper and lower connecting plate of car load direction post, therefore, the utility model has improved bending strength greatly than the front set absorber of same specification breeches pipe.
