Description

Forked sealing convex rib structure

Technical Field

The utility model belongs to the technical field of the technique of derailleur sealing system and specifically relates to a divide fork formula to seal protruding muscle structure, in particular to mechanical connection structure.

Background

A plurality of threaded holes are arranged on a sealing surface of a traditional transmission to connect and generate surface pressure required by sealing. The gasket is fixed between the two seal housings, and the seal structure is generally designed such that the fixing hole is provided outside the seal line.

Because the fixing hole is arranged at the outer side of the sealing line in the traditional structure, the requirement on the whole layout space is larger, and the volume and the weight of the part are increased; in addition, because the pressure generated by the bolt connection is in a mode that the connecting line of the two bolts is connected and the fixing hole is arranged at the outer side of the sealing line, the bolts with larger specification and larger torque are needed to achieve the same sealing pressure. Along with the continuous improvement of the electrification level of the automobile, the increase of the volume of parts is not beneficial to the arrangement of the whole automobile, and the increase of the weight can cause the reduction of the driving range of the automobile; this increases the cost of manufacturing the part due to the need for larger gauge bolts and greater torque.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a protruding muscle structure is sealed to branch fork, the position in this structure make full use of hole arranges sealed line on the line of two screw hole central lines, simultaneously, sets up the screw hole in the middle of sealed line, plays effectual sealed effect to the screw hole. Therefore, the space of the hole can be fully utilized, the structural size is minimized, the sealing line is informed to be on the central line of the two threaded holes and coincide with the pressure line of the bolt, and the pressure generated by the bolt is fully utilized. Play the role of saving space. Overcomes the defects in the prior art.

In order to realize the purpose, the technical scheme of the utility model is that: a forked sealing convex rib structure comprises a sealing pad body, wherein the sealing pad body is composed of a sealing pad strip-shaped body and a sealing pad bolt hole distribution body, at least two sealing pad bolt hole distribution bodies are arranged, a sealing pad strip-shaped body is arranged between the two sealing pad bolt hole distribution bodies, the sealing pad strip-shaped body and the sealing pad bolt hole distribution bodies are alternately distributed to form the sealing pad body, two parallel-distributed double-side convex ribs are distributed on the surface of the sealing pad strip-shaped body, the two double-side convex ribs are distributed along the length direction of the sealing pad strip-shaped body, the sealing pad bolt hole distribution body is of a circular structure, bolt holes are formed in the circle center position of the sealing pad bolt hole distribution body, the double-side convex ribs are distributed on the central connecting line of the two bolt holes, two sections of symmetrically-distributed single-side convex ribs are distributed at the sealing pad bolt, the two ends of the single-side convex rib are respectively connected with the end parts of the two-side convex ribs on the two sides into an integral structure, and the height of the two-side convex ribs is greater than that of the single-side convex rib.

The utility model discloses a forked sealing convex rib structure, the space width required by sealing is reduced, which is reduced by 2mm compared with the original space single side, and the whole space can be reduced by at least 4 mm; m6 bolt is used in traditional design, will seal protruding muscle and arrange on the pressure line of bolt, under the unchangeable condition of bolt quantity, the specification is M5's bolt just can satisfy sealed requirement, and this makes whole sealed design space littleer, can reduce entire system's cost simultaneously.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

The utility model discloses a divide fork to seal protruding muscle structure, including sealed pad body 1, it lies in different from prior art: the gasket body 1 is composed of a gasket strip-shaped body 2 and a gasket bolt hole distribution body 3, at least two gasket bolt hole distribution bodies 3 are arranged, a gasket strip-shaped body 2 is arranged between the two gasket bolt hole distribution bodies 3, the gasket strip-shaped body 2 and the gasket bolt hole distribution body 3 are alternately distributed to form the gasket body 1, two parallel-distributed double-side convex ribs 4 are distributed on the surface of the gasket strip-shaped body 2, the two double-side convex ribs 4 are distributed along the length direction of the gasket strip-shaped body 2, the gasket bolt hole distribution body 3 is of a circular structure, bolt holes 5 are formed in the circle center position of the gasket bolt hole distribution body 3, the double-side convex ribs 4 are distributed on the central connecting line of the two bolt holes 5, two sections of symmetrically distributed single-side convex ribs 6 are distributed at the gasket bolt hole distribution body 3, the single-side convex ribs 6 are in a semicircular arc shape, and the single, and the sealing lines are distributed between the outer edges of the sealing gasket bolt hole distribution bodies 3 and the outer edges of the bolt holes 5, so that the sealing lines can be closest to the bolt holes, and the two ends of the single-side convex rib 6 are respectively connected with the end parts of the two-side convex ribs 4 on the two sides to form an integral structure. The above configuration can reduce the width of the gasket strip 2 to about 6 mm.

In specific implementation, the height of the double-side ribs 4 is greater than that of the single-side ribs 6.

The foregoing is a more detailed description of the invention, taken in conjunction with the accompanying preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
