Abstract
The utility model discloses an improved shock absorber for an agricultural tricycle, which comprises a shock absorbing tube, a shock absorbing post, a fork head and a spring cover, wherein the shock absorbing post is arranged in the shock absorbing tube, the fork head is fixedly arranged at the lower end of the shock absorbing tube, the spring cover is fixedly arranged on the shock absorbing post,and a main shock absorbing spring is sheathed on the shock absorbing post under the spring cover. The utility model is structurally characterized in that a spring protective tube is sheathed outsidethe lower part of the shock absorbing tube, the lower end of the spring protective tube is fixedly connected on the fork head, a sub shock absorbing spring is sheathed on the shock absorbing tube andis arranged in an inner cavity of the spring protective tube, the rigidity of the sub shock absorbing spring is smaller than that of the main shock absorbing spring, the lower end of the sub shock absorbing spring is pressed on the fork head, and a force transmission device is arranged between the main shock absorbing spring and the sub shock absorbing spring. The shock absorber has good shock absorbing effect when the tricycle is in the idle load state or the load state.
Description
Technical field
The utility model relates to a kind of vibration damper, is specifically related to a kind of vibration damper that is used for agricultural tricycle.
Background technique
At present, the vibration damper that agricultural tricycle is used comprises damper cylinder and is contained in the interior shock structure of damper cylinder, is with damping spring on the shock structure, the upper end portion of shock structure is connected with the spring lid, be connected with spring abutment on the damper cylinder, the upper end of damping spring withstands on the spring cup, and the lower end of damping spring is pressed on the spring seat.The vibration damper of said structure, in order to satisfy load request, the damping spring rigidity is big, and damping effect is better during load, and vibrations are big during unloaded driving, drive uncomfortable.
The model utility content
The technical problems to be solved in the utility model is at above-mentioned deficiency, all has the vibration damper of good damping effect when a kind of vehicle zero load and load are provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of vibration damper of following structure, comprise damper cylinder, be contained in the shock structure in the damper cylinder, be fixed in the jaw of damper cylinder lower end and be fixed in spring cup on the shock structure, the spring cup below, be set with main damping spring on the shock structure, its structural feature is: be with outside the bottom of described damper cylinder and protect the spring tube, protecting spring tube lower end is fixed on the jaw, protect the spring tube inner chamber and be provided with the rigidity that is sleeved on the damper cylinder secondary damping spring less than main damping spring, the lower end of secondary damping spring is pressed on the jaw, is provided with force-transmitting device between main damping spring and the secondary damping spring.
The vibration damper of said structure, adopt the two-stage spring to carry out damping, during unloaded or low load, because the rigidity of main damping spring is greater than secondary damping spring, main damping spring does not produce resiliently deformable, pressure passes to secondary damping spring by main damping spring by force-transmitting device, has only secondary damping spring to have an effect, the damping effect that vehicle is obtained; When load or heavy duty, increase along with load, shock structure is pressed further in the damper cylinder, main damping spring shrinks secondary damping spring by force-transmitting device, when secondary damping spring is reduced to a certain degree, force-transmitting device is protected the spring tube and withstands no longer and move down, and this moment, main damping spring carrying was also had an effect.
Be not difficult to draw from foregoing description, the utility model all has good damping effect when vehicle zero load and load.
Mode of execution as force-transmitting device, force-transmitting device comprises the pressure spring plate that slides on the damper cylinder, the flip sleeve that contacts with pressure spring plate and the dustproof spring cover that contacts with flip sleeve, pressure spring plate is connected the upper end of secondary damping spring, the following end in contact of dustproof spring cover and main damping spring, the lower limb of dustproof spring cover with protect spring tube top edge and overlap.
As improvement of the technical scheme, be connected with fixed cover on the outer surface on the described damper cylinder, flip sleeve and dustproof spring cover slide on the fixed cover.
