Abstract
The invention discloses a three-arm flange, comprising a board, a cone-shaped boss and a cylindrical through hole which are arranged on the facade of the board, and a cylindrical boss and a cone-shaped groove which are arranged on the back facade of the flange. The bottom of the cone-shaped groove is communicated with the cylindrical through hole, wherein the cone-shaped boss, the cylindrical through hole, the cylindrical boss and the cone-shaped groove are arranged along a same axis. The ends of the three convex arms are formed a bulged platform, respectively. The junction of the platform and the facade of the board is the inner ribbed arc rim. The centers of the inner ribbed arc rim of three platforms are trisection points of the same circumference A. The center of the circumference A is located on the axis of the cone-shaped boss, wherein an outer contour line between the each two convex arms of the board is the inner ribbed arc. The centers of the three inner ribbed arcs are the trisection points of the same circumference B. The center of the circumference B is located on the axis of the cone-shaped boss. According to the invention, the technical scheme has the advantages of reasonable structure, convenient machining and manufacturing, reliable utilization and high cost performance.
Description
Technical field
The present invention relates to a kind of automobile component, relate in particular to a kind of three arm flanges.
Background technique
The chassis effect is supporting, installation motor car engine and each parts thereof, assembly, forms the moulded of automobile, and accepts the power of motor, makes automobile produce motion, guarantees cruising.The chassis by power train, running system, to turn to be to form with Brake System four parts.Three arm flanges are the transmission paries that are connected with transmission shaft, and structural design of these parts itself and quality of processing directly influence the transmission braking ability on chassis.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of three arm flanges, have rational in infrastructure, make things convenient for manufacturing, use reliable, cost performance advantages of higher.
In order to reach above-mentioned purpose, the technological scheme below the present invention has adopted:
A kind of three arm flanges comprise plate body, and the plate body front is provided with a truncated cone boss; Truncated cone boss center is provided with cylindrical hole; The plate body back side is provided with a cylindrical boss, and the cylindrical boss center is provided with the truncated cone groove, and the bottom of truncated cone groove is connected with cylindrical hole and forms step in both joints; Wherein, Said truncated cone boss, cylindrical hole, cylindrical boss and truncated cone groove coaxial line are provided with, and the cone angle of truncated cone boss is 30 °, and the cone angle of truncated cone groove is 10 °; Said plate body has equally distributed three protruding arms; The end of each protruding arm all is formed with one and protrudes from the positive platform of plate body; The positive junction of platform and plate body is convex circular arc edge, and the center of circle at the convex circular arc edge of three platforms is the trisection point of same circumference A, and the center of circle of this circumference A is positioned on the axis of truncated cone boss; Wherein, Plate body is interior concave circular arc at the outer contour between the protruding arm in twos, and the center of circle of three interior concave circular arcs is the trisection point of same circumference B, and the center of circle of this circumference B is positioned on the axis of truncated cone boss.
The present invention has been owing to adopted above technological scheme, have rational in infrastructure, make things convenient for manufacturing, use reliable, cost performance advantages of higher.
