Description

Shock absorber with sensitive damping adjustment

Technical Field

The utility model relates to an automobile shock absorber technical field, specific saying is the shock absorber that is equipped with sensitive damping and adjusts.

Background

With the rapid development of the automobile industry in the years, the automobile models at home and abroad are more and more abundant. Customer demands for vehicle handling and ride comfort are also increasing. However, due to the high price of the active damper. Except for some high-end models, most vehicles on the market now use conventional passive shock absorbers. The conventional shock absorber is limited by the valve train structure and cannot simultaneously provide a low damping force at a high frequency and a low amplitude, such as when a deceleration strip is used, and a high damping force enough to keep the posture of the vehicle body stable at a low frequency and a high amplitude. Sometimes, the balance between the active type shock absorber and the passive type shock absorber is difficult to achieve, and the gap between the active type shock absorber and the passive type shock absorber needs to be made up urgently.

It is therefore necessary to design shock absorbers with sensitive damping adjustment.

The spring disc and the support are arranged outside the outer barrel, the spring disc is located on the upper portion of the outer barrel, and the support is located on the lower portion of the outer barrel.

A dust cover is arranged between the piston rod and the outer cylinder.

An oil seal is arranged between the guider and the outer cylinder.

Compared with the prior art, the utility model, have SDC 2's shock absorber through the installation, can be according to the nimble damping force who adjusts the shock absorber of road conditions, comfort level when satisfying the low amplitude of high frequency simultaneously can guarantee again that the automobile body of the high amplitude of low frequency is stable, improves user's comfort level.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-3, the utility model designs a shock absorber with sensitive damping adjustment, including piston rod 1, supporting seat 4, sensitive damping adjustment system 5, piston valve 6, bottom cap 8, bottom valve 9, inner tube 10, outer tube 11, director 12, SDC2 valve 13, work spring 14, stop spring 15, SDC2 supporting seat 16, spring preloading valve piece 17, inner tube 10 inserts in outer tube 11, it is fixed through bottom cap 8 of inner tube 10 bottom, inner tube 10 entrance is equipped with director 12, piston rod 1 inserts in inner tube 10 through director 12, the last notch cut that has of piston rod 1, supporting seat 4 is connected with piston rod 1 through the riveting, sensitive damping adjustment system 5 is installed to the lower extreme of piston rod 1, sensitive damping adjustment system 5 includes SDC2 valve 13, work spring 14, stop spring 15, spring preloading valve piece 17, the both ends symmetry of SDC2 valve 13 is equipped with spring valve piece 17, the spring preloading valve plate 17 is connected with the working spring 14, the stop spring 15 is embedded into the working spring 14, the lower end of the stop spring 15 is connected with the piston valve 6, the SDC2 supporting seat 16 is arranged between the stop spring 15 and the piston valve 6, the bottom of the piston rod 1 penetrates through the SDC2 supporting seat 16 and the piston valve 6, the bottom of the inner cylinder 10 is provided with the bottom valve 9, and the bottom valve 9 is connected with the bottom cover 8.

The spring disc 3 and the support 7 are arranged outside the outer barrel 11, the spring disc 3 is positioned at the upper part of the outer barrel 11, and the support 7 is positioned at the lower part of the outer barrel 11.

A dust cover 2 is arranged between the piston rod 1 and the outer cylinder 11.

An oil seal is arranged between the guider 12 and the outer cylinder 11, and can play a role of sealing.

In the running process of a vehicle, the shock absorber provided with the SDC2 valve 13 does not generate damping force by the SDC2 valve 13 under the working condition of high frequency and low amplitude, and only the piston valve 6 and the bottom valve 9 generate the damping force, so that the damping force is lower, and the small damping force can meet the comfort level of an occupant under the working condition of high frequency and low amplitude; at low frequency and high amplitude, the SDC2 valve 13 will float to the top and bottom dead center positions, the stop spring 15 limits the valve to continue floating, the damping force value is the sum of the damping force of the piston valve 6 and the bottom valve 9 plus the SDC2 valve 13, and when the piston rod 1 is stretched or compressed, the oil pushes the spring pre-loaded valve plate 17 on the SDC2 valve 13 to generate additional damping force.
