Abstract
The utility model discloses an air bag type damper, comprising a damper body, an air bag, a support saddle and a connection board. The support saddle is closely covered on the damper body; the connection board is closely covered on the piston rod at the upper part of the damper body; two ends of the air bag are respectively covered on the connection board and the support saddle; the support saddle is arranged with an air hole to communicate the air bag and the outside. By adopting the technic proposal, the utility model has the advantages of strong adaptability to meet the needs of different pavements, good comfortability, simple structure, low manufacturing cost; only an air bag is needed to be covered on the outer side of the prior damper, thus a complete separation of oil and air is realized to avoid the reaction between the damper oil and air in high temperature completely and further the emulsification phenomenon, ensuring the damping effect of the damper well; in order to increase the air tightness of the air bag, a fastening sleeve is arranged at each end of the air bag, and a sealing saddle is arranged on the connection board as well as the piston rod of the damper body.
Description
Technical field
The utility model relates to the technical field of vibration damper, more particularly relates to a kind of air-cushion shock absorber that is used on the automobile.
Background technique
Vibration damper can both be seen on various automobiles, the quality of its vibration damper quality can directly have influence on the travelling comfort of automobile, at present, employed vibration damper all is air-cushion shock absorbers on most of high-grade automobiles, and following 2 deficiencys of present air-cushion shock absorber ubiquity, the first can not the different road surfaces of fine adaptation demand, it two is that what to adopt is that oil gas is hybrid, its complex structure, the manufacture cost height, vibration damper is in when work, its connecting rod and guide holder and oil sealing, the rubbing action between piston and the clutch release slave cylinder, oil temperature in the vibration damper is constantly raise, gas and shock absorber oil in the vibration damper react under high temperature condition, and shock absorber oil will produce emulsion, will have a strong impact on the damping property of vibration damper.
The model utility content
The purpose of this utility model provides a kind of simple in structure in order to solve the problems of the technologies described above exactly, low cost of manufacture, and adaptability is strong, and travelling comfort is good, and the air-cushion shock absorber that separates fully of oil gas.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Air-cushion shock absorber, comprise damper main body, air bag, bearing and connecting plate, bearing closely is nested with on damper main body, connecting plate closely is nested with on the piston rod of damper main body upper end portion, the two ends of air bag closely are nested with respectively on connecting plate and bearing, offer pore on the bearing, air bag is in communication with the outside.
The outer opening of described pore is provided with valve.
A described end that is nested with at the bearing upper gasbag also is provided with adapter sleeve.
A described end that is nested with at the connecting plate upper gasbag also is provided with adapter sleeve.
Also be provided with sealing seat between the piston rod of described connecting plate and damper main body upper end portion.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: adaptability is strong, the needs that can adapt to different road surfaces, travelling comfort is good, simple in structure, low cost of manufacture, only be to be nested with an air bag again in the outside of original damper main body to get final product, so just accomplished Oil-gas Separation fully, also just avoided shock absorber oil under high temperature condition, to react fully with air, and the emulsion that occurs, favourable assurance the effectiveness in vibration suppression of vibration damper, in order to increase the tightness of air bag, two ends at air bag are provided with adapter sleeve, and on the piston rod of connecting plate and damper main body sealing seat are set also.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
By shown in Figure 1, air-cushion shock absorber, comprise damper main body 1, air bag 2, bearing 3 and connecting plate 4, bearing 3 closely is nested with on damper main body 1, in order to increase the tightness of 1 of bearing 3 and damper main body, be provided with seal ring 5 at bearing 3 and 1 of damper main body, connecting plate 4 closely is nested with on the piston rod of damper main body 1 upper end portion 6, equally, in order to increase the tightness of 6 in connecting plate 4 and piston rod, be provided with sealing seat 7 at connecting plate 4 and 6 in piston rod, and all also be provided with seal ring 8 between sealing seat 7 and the piston rod 6 and between sealing seat 7 and the connecting plate 4, the two ends of air bag 2 closely are nested with respectively on connecting plate 4 and bearing 3, and also be provided with adapter sleeve 9 at the two ends of air bag 2,10, on bearing 3, offer pore 11, this pore 11 is in communication with the outside air bag 2, be used in air bag 2, inflating by this pore 11, for the ease of keeping in repair and make-up gas in air bag 2 with rear gasbag 2, can also valve 12 be set at the outer opening of this pore 11, if the central control unit on the utility model and the automobile is used, can realize making automobile lifting voluntarily on different road surfaces, improve the travelling comfort of automobile to greatest extent.
