Abstract
The utility model relates to a damper of a motorcycle, which is provided with a damping device. A detachable seal ring is arranged between the end of a hydraulic cylinder and a movable piston rod. The device with the advantages of obvious vibration damping effect and reasonable structure is an ideal vibration damping device for the motorcycle.
Description
The utility model relates to the elastic vibration clamper of a kind of Motor Vehicle, particularly motorcycle.
The vehicle frame of general motorcycle all has a cover vibration damping equipment, the vibration that produces when alleviating motorcycle driving, and vibration acutely makes the cyclist feel bad very much.For vibration damping, technique known has spring cushion, or oil gas mixing vibration damper etc., for example a known air oil shock absorber etc. generally all comprises a ram pot and makes movingly piston with the ram pot inner chamber, piston is connected with piston rod, ram pot one end and wheel shaft are hinged, be with a pressure spring on the stack shell, and be provided with the device that spring is located along the stack shell axis, the other end of pressure spring is connected with a gland, described gland and vehicle seat are movably hinged, the affixed piston rod of the other end; Oiling in the piston cylinder, or oil gas mixing are not leaked for making oil, and nozzle is provided with seal ring, in order to obtain slow shaking, be provided with rubber damping etc. piston rod and vehicle seat hinged, but these structures have plenty of disposable, mounting or dismounting are difficult for, and it is undesirable to have plenty of effect, and it is necessary therefore improving.
The purpose of this utility model is to provide that a kind of effectiveness in vibration suppression is obvious, durable, the quick-wear part mounting or dismounting are easy to damper of motorcycle.
For achieving the above object, scheme of the present utility model is, a kind of damper of motorcycle, be provided with a ram pot, and and ram pot inwall work piston movingly, piston is connected with piston rod, and ram pot one end and wheel shaft are hinged, overlaps a pressure spring and be provided with the device that makes spring one end location on stack shell, the other end of pressure spring is connected with a spring capping, described gland outer end and vehicle seat are hinged, and the other end is fixedlyed connected with hydraulic rod, particularly, its hydraulic rod is hollow, disconnectable seal ring is housed between the end of ram pot and the hydraulic rod, and ram pot and piston in position are drilled with the hole of its unlatching of may command, particularly piston.
By adopting said apparatus, then be easy to realize the purpose of this utility model.
Below in conjunction with diagram and embodiment the utility model scheme is described in more detail.
Be illustrated as the front view of damper of motorcycle.
As shown, this vibration damper is provided with a hydraulic pressure installation, comprise ram pot (1), hydraulic piston (2), and the piston rod (3) that is connected with piston (2), a cover pressure spring (4) on the stack shell of ram pot (1), one end of spring (4) props up the positioning device (5) that is located on the stack shell, the other end is connected with a spring capping (6), one end of ram pot (1) has a garden ring (7) with holes, and hinged by pivot pin and vehicle seat, spring capping (6) is hinged by hole (8) and vehicle seat, the other end is fixedlyed connected with hydraulic rod (3), and present embodiment is fixing by screw thread.Hydraulic rod (3) is hollow, is fixed with piston (2) at the free end of hydraulic rod (3).
End at hydraulic rod (3) and ram pot (1) is provided with seal ring (9), a described seal ring (9) and a fixed cover (10) are stacked in the end of ram pot inwall, and seal ring (9) is fixing by the ring washer that is positioned at the ram pot end (11) up and down with fixed cover (10).
Be drilled with hole (12) on the piston (2), described hole (12) is vertical with the end face of piston (2), unlatching for control hole (12), be provided with a plane valve (13), described valve (13) is an annulus with the piston rod location, its end face is close on the hole (12), is provided with the back-up ring (14) of control valve (13) position in the appropriate location of piston rod.
Go up near shelves figure (14) at piston rod (3) and to be drilled with hole (15), the neglecting the power that needs vibration damping greatly and decide of hole (15).
Be provided with filler opening (16) in the bottom of ram pot, shut with the oil sealing screw after the oiling.
The working principle of this vibration damper is as follows: when motorcycle driving during on mild road surface, vibration insulating system relies on the elastic damping of spring.When motorcycle builds up speed, or when travelling on the road surface situation in bad order, the people is thrown to fall to very big active force of vehicle seat then heavyly, so spring is compressed, when beginning is to be compressed rapidly, spring capping drives piston rod and piston presses down rapidly, so filling with the cavity of oil and air is compressed, the pressure of an oily gas mixture is increased, make the piston downward speed that slows down for the reaction force of piston, iff being like this, the reaction force that this oil gas mixes can give reaction of spring soon and stop spring again toward lower compression, also promptly give reaction force of cyclist and make the cyclist uncomfortable, but because this programme also has its its feature, when the pressure of in-oil cylinder gas mixture reaches certain value, oil one gas mixture backs down valve (13) by the aperture on the piston (12) and enters in the top cavity, be full of top cavity and order about piston (2) and move downward, but the speed of this piston motion is by the pressure difference decision of two cavity oil gas mixture, thereby piston only is to move downward very lentamente, the reaction force that gives vehicle seat is very little, makes the cyclist feel very mildly to fall.When the cavity pressure on top during greater than the gas mixture pressure of lower cavity, the piston stop motion is so the compression process of spring stops.When spring extended under the elastic force effect, it was up to drive piston rod, above the oil of cavity be compressed to get back in the oil cylinder and go by aperture (15), so a dynamic process finishes.Said process be it seems more intuitively from the viewpoint of vibration, and spring system is a vibration system, and oil gas is a damping device, and vibration is owing to be subjected to the decay of damped system, drives in steadily so vibration weakening motion gradually.
The utility model is practical on principle, structurally because the structural type of seal ring (9) is convenient to dismounting and change, and the seal ring of prior art is disposable, can't change, and therefore uses this structure more economical.
In sum, the utility model is effective.
