Abstract
The utility model relates to an air exhaust valve for automobile air compressor, which comprises an air exhaust valve plate, a spring piece, a guide sleeve, a screw bolt, a limiting plate and a valve plate, wherein the limiting plate floated restricts the two ends of the air exhaust valve plate on the valve plate, a spring piece and a cushioning spring piece are installed between the upper part of the air exhaust valve plate and the limiting plate, the air exhaust valve plate is limited on the valve plate by the stamping positioning flange of the limiting plate and the air exhaust valve plate is fixed on the valve plate by a positioning pin. Only the spring piece is installed between the air exhaust valve plate and the limiting plate. The air exhaust valve structure greatly improves the service life of the air exhaust valve plate, makes the exhaust valve plate not produce upward and downward bending deformation under the exhaust pressure, not lose effectiveness, and reduce the noise. Moreover, the floating exhaust valve has the advantages of simple structure and easy processing.
Description
Technical field
The utility model relates to a kind of automobile air compressor outlet valve, belongs to the braking air compressor technical field of auto manufacturing technology.
Background technique
At present, the used braking of medium and heavy cargo vehicle is generally adopted two kinds of structures with the air valve of air compressor: (1) ring valve (2) Reed Valve.Because the ring valve clearance volume is big, charging efficiency is low, complex structure; The Reed Valve clearance volume is little, and the charging efficiency height is simple in structure, and long service life; So extensively adopt Reed Valve now, substituted ring valve gradually.And the structure of reed outlet valve all adopts the end with exhaust valve plate to be fixed on the valve plate at present, the X of space coordinates, Y, all there is not degrees of freedom on the Z direction, and the other end prevents that by being fixed on the guide sleeve on the valve plate or increasing the degrees of freedom that mode such as defining flange limits Y direction on the valve block limiting board exhaust valve plate from rotating.When the exhaust port exhaust, the stream pressure that exhaust valve plate is subjected to making progress makes exhaust valve plate produce resiliently deformable and is bent upwards; When air compressor is air-breathing, exhaust valve plate is owing to be subjected to downward stream pressure and the elastic deformation force of itself, make it return to original state, near each work cycle of the air compressor fixed end of exhaust valve plate, in exhaust process, produce bending deflection up and down, resiliently deformable repeatedly makes exhaust valve plate reach yield limit and produces crooked fatigue fracture at the exhaust valve plate root.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile air compressor outlet valve, and exhaust valve plate and limiting board structurally improve, and the orientation type of exhaust valve plate is completely fixed by an end and is floating type with the floating type two ends that change into of an end; Improved the working life of exhaust valve plate, can make exhaust valve plate under exhaust pressure, not produce up and down bending deflection, do not lost efficacy, and reduced noise.
The technical solution of the utility model is achieved in that the automobile air compressor outlet valve, form by exhaust valve plate, spring sheet, damping spring sheet, guide sleeve, bolt, limiting board, valve plate, wherein limiting board is limited on the valve plate the exhaust valve plate two ends are floating type, spring sheet and buffering spring sheet are housed between exhaust valve plate top and limiting board, exhaust valve plate can be limited on the valve plate with the punching press defining flange of limiting board, and exhaust valve plate can also be limited on the valve plate with locating stud.Between exhaust valve plate and limiting board, also spring sheet can only be housed.
Good effect of the present utility model is that when the exhaust port exhaust exhaust valve plate is subjected to the upwards unsteady bending elasticity up and down of having avoided of exhaust pressure and is out of shape; Improved the working life of exhaust valve plate widely, and can under exhaust pressure repeatedly, not produce bending deflection up and down, do not lost efficacy, and reduced noise.Floating type exhaust valve plate simple in structure, processing easily.
Description of drawings
Fig. 1-2 is first kind of structural representation of the present utility model;
Fig. 3 is second kind of structural representation of the present utility model;
Fig. 4 is the third structural representation of the present utility model;
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described: the automobile air compressor outlet valve, form by exhaust valve plate 1, spring sheet 3, damping spring sheet 4, guide sleeve 7, bolt 8, limiting board 2, valve plate 6, wherein limiting board 2 is limited in exhaust valve plate 1 two ends floating ground on the valve plate 6, spring sheet 3 and buffering spring sheet 4 are housed between exhaust valve plate 1 top and limiting board 2, exhaust valve plate 1 can be limited in the punching press defining flange of limiting board 2 on the valve plate 6, and exhaust valve plate 1 can also be limited on the valve plate 6 with locating stud 5.Between exhaust valve plate 1 and limiting board 2, also spring sheet 2 can only be housed.
As illustrated in fig. 1 and 2, the orientation type that exhaust valve plate 1 is fixing by an original end and an end floats changes two ends into and is floating type, and spring sheet 3 and buffering spring sheet 4 are housed between exhaust valve plate 1 top and the limiting board 2, limiting board 7 is fixed on the valve plate 6, when exhaust, exhaust valve plate 1 is stressed upwards unsteady, because top has the space that exhaust valve plate 1 can be set back, so well exhaust can improve the working life of exhaust valve plate 1 again.As shown in Figure 3, exhaust valve plate 1 is limited on the valve plate 6 by the defining flange on the limiting board 2.As shown in Figure 4, exhaust valve plate 1 is limited on the valve plate 6 by cylinder locating stud 5, also can only omit damping spring sheet 4 with spring sheet 3.Perhaps other the exhaust valve plate 1 ground structure form of on valve plate 6, floating.
Claims (4)
1, automobile air compressor outlet valve is made up of exhaust valve plate (1), limiting board (2), spring sheet (3), damping spring sheet (4), valve plate (6), guide sleeve (7), bolt (8); It is characterized in that: limiting board (2) is limited in exhaust valve plate (1) two ends floating ground on the valve plate (6), and spring sheet (3) and buffering spring sheet (4) are housed between exhaust valve plate (1) top and the limiting board (2).
