Embodiment
Through embodiment,, do further bright specifically below to the technological scheme of the utility model in conjunction with accompanying drawing.
Embodiment 1.
As shown in Figure 1, a kind of damping shock absorption device is nested in the aluminum barrel 1 by a fork arm 2; Opening end at aluminum barrel is provided with the airtight active chamber 4 of oil sealing 3 formation; Be positioned at this active chamber by damper rod 5 and long spring 6 through the damping force controlling device 10 that link connects and composes, described damper rod 5 constitutes built-in spring by pipe 12 in piston rod 11 parcels; Reduced the overall volume of vibration damper, structure is compact more.
One end of said damper rod is provided with two mutually perpendicular damping holes 7; Damping hole 7 is key influence factors of hydraulic shock-absorption effect, and mutually perpendicular damping hole increases the polytrope of damping oil flow direction; Glide path is circuitous, tortuous; Prolong the time that damping force changes, strengthened the effect of hydraulic shock-absorption, comfort level increases in the damping process; Damper rod 5 should be connected with aluminum barrel 1 by end, and the sealing of both tie points, in case oil leakage phenomenon; Aluminum barrel 1 one ends are provided with mounting hole 18, and aluminum barrel 1 end of vibration damper can be fixed on the wheel axle of vehicle through this mounting hole 18; Damper rod 5 is connected with long spring 6, and long spring 6 is connected with fork arm 2 again, and fork arm 2 peripheries are provided with dust-proof cover 9, and fork arm 2 one ends are provided with chock plug 19, and seal ring 20 is arranged on the chock plug 19, to guarantee to form airtight working space; The chock plug 19 of fork arm is as the tie point of vibration damper and headstock; Described piston rod 11 is supported by a buffering bearing 13; This buffering bearing 13 connects two bearings 15 by a little spring 14 two ends and constitutes; On near long spring 6 bearing on one side, piston ring 16 and fork arm 2 flexible connections are set, an end fixing seal that stretches into aluminum barrel 1 at fork arm 2 overlaps 17, and sealing is overlapped 17 ring sets on piston rod 11; And be connected with buffering bearing 13; Two cushion holes 8 along damper rod 5 linear array that are provided with on the damper rod 5 cooperate with stuffing box gland 17 and buffering bearing 13, utilize the elastic strain of spring to influence the relative movement of aluminum barrel 11 and fork arm 2; 17 pairs of active chambers 4 of stuffing box gland are separated, and between aluminum barrel 1 and piston rod 11, form airtight cavity a21, and another cavity b22 that interior pipe 12 forms and cavity a21 are through damping hole 7 UNICOMs, and damping hole 7 is as the changing channel of damping oil.
When vibration damper receives less vertical pressure, only need the elastic strain generation restoring force of the long spring 6 of utilization to reach damping effect, the 13 main effects of buffering bearing are to reduce the displacement of aluminum barrel 1 and fork arm 2, the balance of maintenance hydraulic pressure as far as possible in this process; When vibration damper received great vertical pressure, only the elastic strain by long spring 6 was not enough to produce enough restoring forces, and excessive pressure makes the relative displacement of 2 of aluminum barrel 1 and fork arms increase fast; The damping force that the mobile generation of the variation of hydraulic pressure and damping oil constantly changes, in this process, the main effect of buffering bearing 13 is to slow down the increase and the minimizing of relative displacement; Prolong the time that damping force changes; Improve damping effect, make the process of damping relax more, feel more comfortable.
In the using process; The aluminum barrel end of vibration damper is fixed on the front wheel spindle of motorcycle through mounting hole; And that end of the chock plug of fork arm is fixed on the headstock, and when motorcycle crossed protruding on the road surface, front-wheel can up be lifted; Thereby form the relative movement between aluminum barrel and the fork arm, can be pressed into the damping oil among the cavity a among the cavity b through damping hole this moment; And when front-wheel fell, because the elastic force effect of long spring promotes aluminum barrel and moves downward, the damping oil among the cavity b flow back among the cavity a through damping hole again, the bigger shock transfer on the front-wheel to headstock the time vibrations just fainter; Less when the vibrations that motorcycle receives, damping process is so accomplished through elastic strain by long spring.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
