Abstract
The invention discloses a damping device, which comprises a shock absorber and a first supporting spring, wherein the first supporting spring is sheathed on the outer side of the shock absorber; one end of the first supporting spring is fixedly arranged on the outer side wall of the shock absorber; the other end of the first supporting spring is arranged on a spring gland; the first supporting spring is provided with a spacing block; the spacing block is vertically moved along with the extension and the compression of the first supporting spring; the shock absorber is at least sheathed with a second regulation spring; one end of the second regulation spring is fixedly arranged on the outer side wall of the shock absorber; and the other end of the second regulation spring is arranged below the spacing block for a certain distance. According to the damping device disclosed by the invention, two springs are arranged on the shock absorber; when the first supporting spring is downwards moved under the vibration, the spacing block is downwards moved; when the second regulation spring is touched by the spacing block, the spacing block drives the second regulation spring to downwards move; and the buffer force is largened so as to change the buffer force characteristic and improve the driving stability.
Description
Technical field
The present invention relates to a kind of damping device, be used for buffering passes to vehicle according to road conditions vibration.
Background technique
[0002] vehicle set has suspension system usually, in driving procedure, strengthens driving comfortability by buffering from impact or the vibration that reason is delivered to vehicle bridge, and one of them parts that consists of suspension system are vibration dampers.Vibration damper is arranged between vehicle bridge and the vehicle body.Vibration damper comprises cylinder and reciprocating piston rod in cylinder.Cylinder is filled with working fluid, for example gas or oil, thereby thereby working fluid is moved by piston valve and produces cushion effect, and described piston valve is fixed to an end of piston rod.
Common vibration damper generally all has constant damping force characteristics, and therefore low damping force characteristics can improve the driving comfortable feel, but can not guarantee the stability of vehicle.On the contrary, high damping force characteristics can keep the stable attitude of vehicle, descends but cause driving comfortable feel.Like this, common vibration damper can not be controlled damping force characteristics in response to the variation of road conditions or vehicle attitude.
Therefore in order to solve this problem of traditional shock absorber, improve the travelling comfort of driving and handling, work out a kind of vibration damper that changes damping force characteristics necessary.
Summary of the invention
The present invention is directed to the prior art deficiency, a kind of damping device is provided, this kind damping device can change damping force characteristics along with moving of piston rod, thereby improves the travelling comfort of driving.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: damping device, comprise vibration damper and the first supported spring, described the first supported spring is set in the vibration damper outside, described the first supported spring one end is fixed on the vibration damper outer side wall, the other end is arranged on the spring capping, be provided with limiting stopper on described the first supported spring, described limiting stopper is along with the elongation of the first supported spring and compression move up and down, at least also be arranged with the second Regulation spring on the described vibration damper, described the second Regulation spring one end also is fixed on the vibration damper outer side wall, and the described second Regulation spring the other end is arranged on from the below of limiting stopper one segment distance.At damping device two springs are set, the first supported spring is subject to vibrating when moving downward, limiting stopper also moves downward, limiting stopper drives the second Regulation spring and moves downward when limiting stopper touches the second Regulation spring, so that cushion effect becomes large, thereby changed damping force characteristics, improved the stability of driving.
In the technique scheme, preferably, be provided with spring seat on the described vibration damper outer side wall, described the first supported spring and described the second Regulation spring all are arranged on the spring seat, spring seat is set so that the installation of spring on vibration damper becomes convenient, and fixes more firmly.
In the technique scheme, preferred, be provided with some radiating fin on the described vibration damper sidewall.Can produce a large amount of heats because vibration damper vibrates back and forth, the excess Temperature meeting arranges the temperature that radiating fin can effectively reduce vibration damper so that the vibration damper rate of wear is accelerated, and prolongs the life-span of vibration damper.
In the technique scheme, preferably, described limiting stopper is arranged on the centre of the first supported spring, be provided with two the second Regulation springs on the described vibration damper, described two the second Regulation springs are separately positioned on described limiting stopper both sides, described two the second Regulation spring one ends are fixed on the vibration damper outer side wall, and the other end is separately positioned on from the both sides of limiting stopper one end distance.
The present invention compared with prior art, have following beneficial effect: the present invention arranges two springs at damping device, the first supported spring is subject to vibrating when moving downward, limiting stopper also moves downward, limiting stopper drives the second Regulation spring and moves downward when limiting stopper touches the second Regulation spring, so that cushion effect becomes large, thereby change damping force characteristics, improved the stability of driving.
