Abstract
The utility model relates to a damping adjusting mechanism of a non-delay time highly-reliable vibration damper with adjustable damping, which includes an inner shaft arranged in an axial through hole in a piston rod of the vibration damper; a sliding center integrated with the inner shaft is arranged at the bottom of the inner shaft; the sliding center is in threaded fit with the axial through hole at the bottom of the piston rod; the inner shaft is in drive connection with an electric adjusting system; a piston is arranged at the bottom of the piston rod, and a first flow hole is arranged on the piston; a second flow hole is arranged at the threaded matching section of the bottom part of the piston rod and the sliding center; and the electric adjusting system drives the inner shaft to rotate, and further adjust the position of the sliding center, so as to adjust the opening degree of the second flow hole and finally realize damping adjustment. When the vibration damper is in work, the damping of the vibration damper is adjusted through the opening or the closing of the electric adjusting system, that is, the electric adjusting system controls the sliding center to move downward to a limit position to close the second flow hole, thereby increasing the damping, and on the contrary, the damping is reduced.
Description
Technical field
The utility model relates to a kind of damper regulation mechanism of vibration damper.
Background technique
In the suspension system of automobile,, elastic element produces vibration because being hit, for improving vehicle running smoothness, be installed in parallel vibration damper with elastic element in the suspension, be attenuation vibration, adopt vibration damper to be mostly hydraulic shock absorber in the automobile suspension system, its working principle is that the piston in the vibration damper moves up and down when being subjected to vibration relative movement to occur between vehicle frame (or vehicle body) and vehicle bridge, and the fluid in the vibration damper chamber just flows in another chamber through different holes from a chamber repeatedly.The intermolecular interior friction of friction between hole wall and fluid and fluid at this moment forms damping force to vibration, makes automobile vibrational energy be converted into fluid heat energy, is dispersed in the atmosphere by the vibration damper absorption again.
Vibration damper of the prior art is located at the top and piston rod 5 screw-thread fit of the interior axle 4 in the piston rod 5 as shown in Figure 1; During work, axle 4 rotations in motorized adjustment knob 1 drives, because the top and piston rod 5 screw-thread fit of interior axle 4, interior axle 4 is two individual components that are distributed in up and down in the piston rod 5 with slip thimble 17, because the lower end of axle 4 in in-oil cylinder hydraulic pressure, slip thimble 17 withstand on is by the aperture of described second opening 28 of displacement may command of axle 4 in controlling, thereby play the effect of damming, promptly realize the damping adjusting.
There is following deficiency in the prior art: interior axle 4 is split-type structural with slip thimble 17,4 a moment in rapid adjustment to top offset, often there is the gap between interior axle 4 and the slip thimble 17, causes damping to be regulated and have bigger time-delay, influenced the using effect of vibration damper; In addition, in case slip thimble 17 exists by impurity situations such as " stuck ", this vibration damper has just lost the damping regulatory function, and promptly reliability is lower.
The model utility content
Technical problem to be solved in the utility model provides the damper regulation mechanism that a kind of simple in structure, Adjustable Damping joint does not have time-delay and reliability better damping device.
For solving the problems of the technologies described above, the utility model provides a kind of damper regulation mechanism of vibration damper, comprising: be arranged on the interior axle in the axial hole in the piston rod of vibration damper, the bottom of interior axle be provided with should in the slip thimble of axle one; The axial hole screw-thread fit of slip thimble and piston rod bottom; Interior axle is in transmission connection with described electronic adjustment system; The bottom of piston rod is provided with piston, and piston is provided with first-class through hole; The screw-thread fit section with described slip thimble of piston rod bottom is provided with second opening; Described electronic adjustment system drives described interior axle rotation, and then adjusts the position of described slip thimble, to adjust the aperture of described second opening, promptly realizes the damping adjusting.
Vibration damper when work, close or open by electronic adjustment system, regulate the resistance of shock absorber size, when electronic adjustment system is controlled described slip thimble and is displaced downwardly to limit position, described second opening is closed, make the damping increase, otherwise, then deattenuation.
The utlity model has positive effect: in the damper regulation mechanism of vibration damper of the present utility model, interior axle is made one with the slip thimble, when described electronic adjustment system drives described interior axle rotation and adjusts the position of described slip thimble, the gap that does not have moment between interior axle 4 and the slip thimble, aperture that promptly can described second opening of rapid adjustment has realized that the Adjustable Damping joint does not have time-delay; In addition, because described electronic adjustment system and interior axle directly are in transmission connection, interior axle is one with the slip thimble, and the rotating power on the slip thimble is bigger, so be not prone to by the situation of impurity " stuck ", promptly reliability is better.
