Technical Field

The invention belongs to the technical field of automobile parts, and particularly relates to a reinforced end face tooth flange yoke for a commercial vehicle.

Background

The flange is also called a flange plate or flange. The flange pipe fitting is a part for connecting a pipe and a pipe with each other, is connected to a pipe end, is provided with holes for bolts to pass through so as to enable the two flanges (flanges) to be tightly connected, is sealed by a gasket between the flanges (flanges), and can be formed by casting or connected by threads or welded.

As in application No.: 201720951323.8 the invention provides a flange yoke, comprising a flange body, a pair of ear yokes arranged on one side surface of the flange body, a step hole extending towards the ear yokes arranged on the other side surface of the flange body, a large diameter hole in the step hole is positioned on the outer side of the hole, a small diameter hole in the step hole is positioned on the inner side of the hole, a sealing sleeve is coaxially arranged in the large diameter hole, the outer circumferential surface of the sealing sleeve is attached to the inner circumferential surface of the large diameter hole, and the inner circumferential surface of the sealing sleeve is provided with a convex sealing part. The sealing part of the invention can prevent lubricating oil in the small-diameter hole from leaking out of the step hole and prevent impurities such as silt and the like outside the step hole from entering the small-diameter hole, thereby avoiding the corrosion of the pin shaft and the small-diameter hole, facilitating the disassembly of the pin shaft and the flange yoke, prolonging the service life of the flange yoke and reducing the maintenance cost of a transmission part.

The existing commercial vehicle flange yoke does not always have a certain reinforcing structure on the surface of the structure, the ratio of the length to the height of the bottom of the flange yoke is large, when the flange yoke is used for a commercial vehicle transmission system, the probability of transverse fracture is large due to high use strength, and when the end face tooth structure is inserted, the flange yoke is labor-consuming when being inserted due to the fact that an auxiliary sliding structure is not arranged, and during installation, gaps of part prefabricated parts are too tight and are sewn, and installation is labor-consuming.

In view of the above, the present invention provides a reinforced end-toothed commercial vehicle flange yoke which is improved in view of the conventional structure and drawbacks, and is intended to achieve a more practical purpose.

Disclosure of Invention

In order to solve the technical problems, the invention provides a reinforced end face tooth flange yoke for a commercial vehicle, which aims to solve the problems that the existing commercial vehicle flange yoke is not provided with a certain reinforcing structure on the structure surface, the flange yoke has a high length-height ratio at the bottom, when the reinforced end face tooth flange yoke is used for a commercial vehicle transmission system, the probability of transverse fracture is high due to high use strength, when an end face tooth structure is inserted, the insertion is difficult due to no auxiliary sliding structure, and when the reinforced end face tooth flange yoke is installed, gaps of part of prefabricated parts are too tightly matched, and the installation is difficult.

the invention relates to a purpose and an effect of a reinforced end face tooth commercial vehicle flange yoke, which are achieved by the following specific technical means:

A reinforced end face tooth flange yoke for a commercial vehicle comprises a flange yoke blank body, a ball insertion hole, a fixing screw hole and an arc-shaped threshold; the top end of the flange fork blank body is provided with two lug-shaped bulges, and the insides of the lugs are respectively provided with a ball insertion hole with a round hole structure; the base of the flange fork blank body is circular, two fixing screw holes are formed in each side of the base of the flange fork blank body, and the fixing screw holes are symmetrical left and right; the outer edges of the flange fork blank body where the fixed screw hole is located are respectively provided with an arc groove structure, namely an arc-shaped threshold.

Furthermore, the flange fork blank body is of an integrally formed casting structure; the bottom end surface of the flange fork blank is provided with a regular hexagon shallow groove; the regular hexagonal shallow groove is of a fine gap groove structure.

furthermore, the ball jack main body is of a circular hole structure; the inside top of ball jack is equipped with a cavity, and cavity internally mounted has a ball.

furthermore, a raised annular reinforcing structure is arranged outside the fixed screw hole; a longitudinal rifling with a protrusion vertical to the horizontal line is arranged in the fixed screw hole; the longitudinal rifling intersects the internal thread of the screw hole.

Further, an elliptical rubber structure is embedded in the center of the outer wall of the arc-shaped threshold; the surface of the elliptical rubber structure is provided with point-shaped bulges.

Compared with the prior art, the invention has the following beneficial effects:

A protective net-shaped external reinforcing structure is formed through the regular hexagonal shallow groove structure on the surface of the flange fork blank body, and the overall external structural strength is enhanced.

Through the design improvement smoothness when inserting of the inside ball structure of ball jack, when the subassembly inserts the bead fork opening, the ball auxiliary assembly slides.

Through the design of the longitudinal rifling in the fixed screw hole, the surface contact pressure is increased by using the raised rifling structure, and the stability of screw connection is improved.

Through the design of the outer oval rubber structure of arc que kou, the fault-tolerant space of improvement of arc structure, the installation of being convenient for, the punctiform arch on the surface of oval rubber structure is convenient for consolidate fixed position after the installation simultaneously.
