The technical solution that the utility model adopts is:
The vibration damper that shock-stiffness is adjustable, comprises
One reserve tube, up/down perforation, and its sealed bottom is provided with oil sealing and sealing cover;
One piston rod, is up and downly arranged in reserve tube and its lower end and stretches out downwards through described sealing cover;
One piston, it is outer and be positioned at reserve tube that fixed cover is located at described piston rod, and reserve tube is divided into the first chamber and the second chamber by described piston;
One damping spring, is set in outside reserve tube and piston rod external part; And
One controlling device, described controlling device comprises rising block, slide block, adjusting handle and cylinder component, described slide block be placed on outside the external part of piston rod, it is outer and abut against with the lower end of damping spring that described rising block is slidably arranged in slide block, the top of described cylinder component is fixedly connected with rising block, and lower rotational connects described adjusting handle.
Preferably, this vibration damper also comprises the spring seat of honour and spring lower seat, and it is outer and abut against with the upper end of damping spring that described spring seat of honour fixed cover is located at reserve tube, and described spring lower seat is fixedly connected on the lower end surface of described slide block.
Preferably, this vibration damper also comprises upper connection and lower contact, described upper connection is fixedly connected on the upper end open of reserve tube and which is provided with the oilhole and oily cap that are connected with reserve tube, and described lower contact is fixedly connected with described spring lower seat, and the lower end of described piston rod is fixedly connected with lower contact.
Preferably, damping spring and guide sleeve is also provided with between described piston and oil sealing, described damping spring to be arranged between piston and guide sleeve and to be placed on outside piston rod, described guide sleeve arranges near oil sealing and is placed on outside piston rod, by described guide sleeve, piston rod is play the guiding role, make it to closely cooperate with reserve tube, not easy oil leakage.
The beneficial effects of the utility model: when vehicle is subject to impacting suddenly, in reserve tube between the first chamber and the second chamber because there is pressure difference, and liquid is flowed between the first chamber and the second chamber, play the effect of bumper and absorbing shock, again because the lower end at damping spring arranges controlling device, controlling device comprises slide block, rising block, cylinder component and adjusting handle, by rotating adjusting handle, rising block can be slided up and down by opposing slider, then make the precompressed amount of damping spring adjustable, thus it is adjustable to realize shock-stiffness of the present utility model, fast easy to adjust, ensure travelling comfort when riding, stationarity and Security.
