Abstract
The utility model discloses an air spring which comprises a rubber gasbag, wherein the rubber gasbag is fixedly connected with a plastic end cover, a through hole formed on the plastic end cover is hermetically inlaid an inner hole and a metal charging connector which is communicated with a cavity of the rubber gasbag; an inner hole wall of the metal charging connector is provided with an internal thread used for being in screw-thread fit with a charging head of an air compressor, and the plastic end cover is made of plastic; the plastic has the characteristics of high intensity, good tenacity, strong erosion resistance, smooth surface and the like, the quality of the air spring is reduced, thereby achieving the aim of light weight of an automobile; and in addition, the air spring adopts the metal charging connector, and the enough intensity and sealability are guaranteed when the air spring is connected with the charging head of the air compressor.
Description
Technical field
The utility model relates to the pneumatic spring that a kind of air suspension of automobile is used.
Background technique
Air suspension is used to improve automobile running stationarity and travelling comfort, has been widely used on some motorbuss, heavy goods vehicle and the car at present.Pneumatic spring is to be utilized in the flexible closed air chamber to charge into pressurized air as the vitals of air suspension, utilizes the compressibility of air to realize elastic reaction, has functions such as buffering, vibration damping and action.
Existing pneumatic spring comprises rubber pneumatic bag and the end cap that is fixedly installed on the rubber pneumatic bag upper end; End cap is provided with the gas-charging connection that is communicated with the inner chamber of rubber pneumatic bag; Gas-charging connection has the internal thread with the pneumatic head screw-thread fit of air compressor, just can in rubber pneumatic bag, charge into pressurized air through gas-charging connection.But further aggravation along with energy crisis; The energy-conserving and environment-protective design of automobile seems particularly important; Lightweight is an effective way of improving vehicle fuel economy; And the end cap of existing pneumatic spring adopts cast steel or other metallic material, has problems such as quality is heavy, perishable, and the lightweight development and the stablizing of pneumatic spring of automobile all had certain influence.
The model utility content
The purpose of the utility model provides a pneumatic spring, adopts metal end to cause that the pneumatic spring quality is heavier, the corrosion-prone problem of end cap in order to solve existing pneumatic spring.
The utility model adopts following technological scheme: a kind of pneumatic spring; Comprise rubber pneumatic bag; Be fixed with plastic end cover on the said rubber pneumatic bag; Closed set has the metal gas-charging connection that endoporus is communicated with the rubber pneumatic bag inner chamber in the through hole that is provided with on the said plastic end cover, has the internal thread that is used for the pneumatic head screw-thread fit of air compressor on the inner hole wall of metal gas-charging connection.
Said plastic end cover is a multidiameter shaft, and said rubber pneumatic bag has the groove adaptive with the reduced diameter section of plastic end cover, the axis of said metal gas-charging connection and the dead in line of plastic end cover.
The enlarged diameter section end face of said plastic end cover is provided with the stiffening rib that radially extends along plastic end cover.
Adopt the pneumatic spring of said structure, plastic end cover adopts plastics, and characteristics such as intensity height, good toughness, erosion resistance are strong because plastics have, smooth surface have reduced the quality of pneumatic spring, thereby realized the light-weighted target of automobile; In addition, pneumatic spring adopts the metal gas-charging connection, has guaranteed that pneumatic spring has enough intensity and sealing when being connected with the pneumatic head of air compressor.
Utilize the advantage of plastics easy-formation, on plastic end cover, be provided with stiffening rib, to improve the intensity of plastic end cover.
Description of drawings
Fig. 1 is the example structure schematic representation of the utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
The embodiment of the utility model pneumatic spring: like Fig. 1, shown in Figure 2; Comprise rubber pneumatic bag 3 and the plastic end cover 1 that is arranged on rubber pneumatic bag 3 upper ends; Said plastic end cover 1 is a multidiameter shaft; And have the groove adaptive on the rubber pneumatic bag 3 with the reduced diameter section of plastic end cover 1, the reduced diameter section of plastic end cover 1 be inserted into rubber pneumatic bag 3 in groove, what guaranteed that plastic end cover 1 can be firm is fixed on the rubber pneumatic bag 3.Closed set has the metal gas-charging connection 2 of the dead in line of axis and plastic end cover 1 in the through hole of plastic end cover 1; The endoporus of metal gas-charging connection 2 is communicated with the inner chamber of rubber pneumatic bag 3, has the internal thread with the pneumatic head screw-thread fit of air compressor on the inwall of this endoporus.
On the end face of plastic end cover 1 enlarged diameter section, be laid with stiffening rib 4; Stiffening rib 4 constitutes by the bar shaped stiffening rib that extends along plastic end cover 1 radial direction with along the ring stiffener of plastic end cover 1 circumference; The inwall apical grafting of one end of each bar shaped stiffening rib and metal gas-charging connection 2 apical graftings, the other end and ring stiffener can improve the intensity of plastic end cover 1 like this.
In the foregoing description, plastic end cover 1 can adopt means of fixation of the prior art with the means of fixation of rubber pneumatic bag 3.
Claims (3)
