Abstract
The utility model relates to the technical field of automobile dampers, in particular to an automobile compression valve seat which comprises a valve seat body. Elongated damping holes are distributed peripherally and uniformly. The valve seat body and the damping holes can be formed once by means of powder metallurgy to improve production efficiency and reduce production cost. Meanwhile, influences of burrs of the damping holes on a sealing oil piece on an automobile damper can be avoided, and integral performance of the automobile damper can be better guaranteed finally. In addition, the automobile compression valve seat is simple in structure, reasonable in design and low in manufacturing cost.
Description
Technical field
The utility model relates to the automobile absorber technical field, particularly a kind of automobile compression valve seat.
Background technique
Automobile absorber is a kind of damping member, for the rapid wear accessory in the automobile using process, is one of important component part of automobile suspension system, to stationarity, travelling comfort, Security and the steering operation property decisive role of vehicle.Wherein, the compression valve seat is one of key components and parts in the automobile absorber, and it has come the damping throttling action through the oil extraction and the oil suction of the damping hole on the compression valve seat.Brought into play certain function to the even circular damper apertures that distributed existing compression valve seat last week of using in existing automobile absorber.But still have deficiency in the practical application: the fluid amount that flows through damping hole for ability guarantor unit in the time; Need on valve body, process a lot of damping holes; And the space of valve body is very limited; So just make that the spacing between the damping hole is very little, so that can't reinstate powder metallurgy once-through compacting in company with valve body one.Force the processing damping hole to adopt machining process, the efficient of machining is lower, in course of working, is very easy to make the edge of damping hole to produce burr, and burr can influence the effect of sealing oil sheet on the vibration damper, thereby influences the damping performance of car load.How to satisfy the automobile shock performance, provide a kind of compression valve seat simple, that be prone to produce to become the topic of studying in the auto parts machinery industry.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, provides a kind of simple in structure, a kind of automobile compression valve seat reasonable in design, easy to use.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
The described a kind of automobile compression valve seat of the utility model, it comprises valve block, said valve block is provided with damping hole; Said damping hole is the waist shape; Said damping hole is with circumferential even distribution.
Further, said waist shape damping hole is provided with several.
Further, said valve block comprises that the surface of contact that contacts with the outer cylinder dish of automobile absorber is circular-arc.
After adopting said structure; The utility model beneficial effect is: the described a kind of automobile compression valve seat of the utility model; It is provided with waist shape damping hole at valve block, dwindles the distance between the damping hole effectively, makes valve block and damping hole once to push sinter molding with powder metallurgy; Thereby enhance productivity, reduce production costs.Simultaneously, avoid the burr of original damping hole to influence the effect of sealing oil sheet on the automobile absorber, finally guaranteed the performance of automobile absorber effectively.The utlity model has simple in structure, reasonable in design, low cost of manufacture.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model.
Description of reference numerals:
1, valve block; 2, damping hole; 3, surface of contact.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in 2, the described a kind of automobile compression valve seat of the utility model, it comprises valve block 1, said valve block 1 is provided with damping hole 2; Said damping hole 2 is the waist shape; Said damping hole 2 is with circumferential even distribution.Usually the width of waist shape damping hole 2 is bigger than the diameter of existing circular port; Can guarantee the smoothness of oily flow like this; Can reduce the quantity of damping hole 2 again, thereby strengthen the pitch-row between the damping hole 2, make damping hole 2 and valve body 1 can adopt powder metallurgy once to suppress and form; Enhance productivity, reduce cost.
Said waist shape damping hole 2 is provided with several, and the quantity of waist shape damping hole 2 can be confirmed according to the oil mass of valve block 1.
Said valve block 1 comprises the surface of contact 3 that contacts with the outer cylinder dish of automobile absorber for circular-arc, and the surface of contact 3 of existing outer cylinder dish contact is generally plane.When plane width was identical with arc diameter, the surface area of circular arc can be bigger than the surface area on plane; Under the identical situation of axial force, surface of contact 3 unit areas are bigger, and it is stressed just more little, thereby can reduce the wearing and tearing of the surface of contact of outer cylinder chassis and the contact of outer cylinder chassis, the usability and the life-span of improving the compression valve seat.
After the structure with the utility model, valve block and damping hole can be used the powder metallurgy once-through, thereby enhance productivity, and reduce production costs.Simultaneously, avoid the burr of original damping hole to influence the effect of sealing oil sheet on the automobile absorber, finally guaranteed the performance of automobile absorber effectively.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
