Abstract
The utility model relates to a spring cushion oscillating damper suitable for a suspension gear of a vehicle chassis which is mainly characterized in that the oscillating damper is provided with a spring cushion piece in the working cylinder of the oscillating damper; the spring cushion piece is arranged on a piston rod; one end of the spring cushion piece is fixedly connected with a spring seat. The oscillating damper realizes to improve the cushion effect by increasing the cushion distance and time during a piston motion process, thereby eliminating the secondary oscillating brought by impact rebounding, achieving the best effects of lightening the bumping degree of the vehicle, improving the driving comfort, simultaneously reducing the damage of relevant components and prolonging the service life and the reliability of the oscillating damper.
Description
Technical field
The utility model belongs to the damper technique field, is a kind of spring buffer shock absorber that is applicable in the automobile chassis suspension device.
Background technique
In known technology, the vibration damper maximum tension buffering that is used for automobile chassis suspension realizes by a rubber cushion pad, because this rubber cushion pad elastic telescopic is less, in automobile is advanced under the vibratory impulse effect, moment promptly reaches its compression limit, thereby its cushioning effect is poor, and the rubber cushion pad is tired easily and aging, working life is short, often causes buffer invalidation.Especially when the road conditions of travelling are bad, be subjected to the influence of its structure and rubber cushion pad, make the effectiveness in vibration suppression of vibration damper not reach desirable requirement, have influence on and take advantage of the travelling comfort of driving, even can cause the early failue of vibration damper because of the damage ring of this part.
The model utility purpose
The purpose of this utility model provides a kind ofly can strengthen buffer distance, prolong buffer time, improves and takes advantage of the spring buffer shock absorber of driving travelling comfort and effectiveness in vibration suppression.
Realize that the technological scheme that the purpose of this utility model is taked is: this vibration damper is to be provided with spring buffer spare in the clutch release slave cylinder of vibration damper, and spring buffer spare is installed on the piston rod, and the one end is fixedlyed connected with spring seat.
Described spring buffer spare adopts pressure spring.
The spring buffer shock absorber of making according to such scheme, the bigger pressure spring of employing elastic telescopic reduces the impact between piston and the guide holder, and can be by increasing buffer distance and the time in the piston motion process, realize the improvement of cushioning effect, thereby can eliminate the secondary vibration that brings by bump bounce-back effectively, reach and alleviate the vehicle degree of jolting, improve and take advantage of the optimum efficiency of driving travelling comfort, reduce the damage of associated components simultaneously, prolong the working life and the reliability of vibration damper.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, spring buffer shock absorber of the present utility model, form by entrucking hanger 1, dust-proof cover 2, piston rod 3, guide holder 4, spring buffer spare 5, spring seat 6, piston 7, clutch release slave cylinder 8, oil storage cylinder 9 and bottom valve assembly 10, each member is assembled the formation vibration damper successively, wherein, spring buffer spare 5 is installed on the piston rod 3, and be arranged between the guide holder 4 and spring seat 6 in the clutch release slave cylinder 8, the one end is fixedlyed connected with spring seat 6, and the other end can contact with guide holder 4 and separate in piston 7 moving process.Spring buffer spare 5 adopts pressure spring, and has a bigger elastic telescopic distance, thereby when vibration takes place in automobile, can shift to an earlier date and prolong buffer time, thereby absorb the rebounding force of dissolving guide holder 4 more effectively, and eliminate the secondary vibrations that bounce-back thus causes, and reach and alleviate the vehicle degree of jolting, improve and take advantage of the optimum efficiency of driving travelling comfort.
Claims (2)
1, a kind of spring buffer shock absorber is characterized in that: this vibration damper is to be provided with spring buffer spare in the clutch release slave cylinder of vibration damper, and spring buffer spare is installed on the piston rod, and the one end is fixedlyed connected with spring seat.
