Abstract
The utility model provides a combined type air spring of an automobile suspension. The combined type air spring comprises an upper cover, clamping hoops, a capsule shell, a bumper block base, a bumper block and a lower piston. The bumper block is fixed to the bumper block base at the lower end of an upper cover assembly through a screw. The upper end and the lower end of the capsule shell are fixed to the upper cover and the lower piston through the clamping hoops respectively. A spiral spring is arranged on the bumper block base in a sleeved mode. One end of the spiral spring is fixed to the upper end of the upper cover assembly through a locking plate, and the other end of the spiral spring makes contact with the bottom face of an inner cavity of the lower piston. The combined type air spring of the automobile suspension is simple in structure, and the spiral spring in the air spring and the air spring can jointly bear a load, so the bearing capacity is high; the rigidity of the spring is enhanced, so the phenomenon that the offset frequency of an independent suspension system with the overlarge lever ratio is too low to cause poor stability can be avoided; the bearing capacity of the combined type air spring can be adjusted according to the installation height and inflation pressure of the combined type air spring and can also be adjusted by means of changing the size parameters of the spiral spring in the air spring.
Description
Technical field
The utility model relates to a kind of automotive suspension combination type air spring.
Background technique
Current automotive suspension pneumatic spring, is single formula pneumatic spring mostly, and damping rubber block is equipped with in some pneumatic springs inside, but damping rubber block is not used as elastic element.In a lot of compact car suspension systems, owing to being subject to the restriction of arrangement space, be difficult to meet bearing capacity requirement with single formula pneumatic spring.
Summary of the invention
The purpose of this utility model is just to provide a kind of simple in structure, automotive suspension combination type air spring that bearing capacity is strong.
Automotive suspension combination type air spring of the present utility model, comprises upper cover, clip, capsule skin, buffer stopper base, buffer stopper, lower piston, and buffer stopper is fixed by screws on the buffer stopper base of cap assembly lower end,
The upper and lower end of capsule skin is separately fixed on upper cover and lower piston with clip, and helical spring is nested with on buffer stopper base, and helical spring one end is fixed on upper cap assembly upper end with locking plate, and the helical spring the other end contacts with lower piston inner chamber bottom surface.
Automotive suspension combination type air spring structure of the present utility model is simple, helical spring in pneumatic spring can with the common bearing load of pneumatic spring, bearing capacity is strong, by increasing the rigidity of spring, can avoid the excessive independent suspension system offset frequency of lever ratio too low, and cause the bad phenomenon of stability to occur; The large I of its bearing capacity regulates by setting height(from bottom) and the inflation pressure of combined air air spring, also can regulate by the dimensional parameters that changes its internal helicoid spring.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
