Problems solved by technology

The material hardness difference between the spherical shell and the ball pin of the automobile is large, and the long-term frictional contact, especially when the road condition is poor and the ball pin twists and rubs against the spherical shell of the automobile when the vehicle is turning, will cause abnormal wear of the spherical shell of the automobile for a long time
The unreasonable design of the automotive spherical shell will also make the force of the automotive spherical shell unreasonable, and the automotive spherical shell will crack from the stress concentration point, and it will break after long-term movement

Embodiment Construction

[0008] Combine below figure 1 and figure 2 Specific description embodiment:

[0009] Such as figure 1 and figure 2 As shown, the suspension spherical shell includes a ball head 1 and a suspension plate 2. The ball head 1 is a cylinder, and the ball head 1 is provided with a pin hole structure that runs through the upper and lower end surfaces of the ball head 1. 3. The pin hole structure 3 includes an upper hole 31, a middle hole 32 and a lower hole 33. The middle hole 32 is a cylindrical hole, the upper hole 31 is a tapered hole that gradually shrinks from top to bottom, and the lower end of the upper hole 31 is a middle hole. The upper end of the hole 32, the lower hole 33 is a U-shaped hole; the suspension plate 2 is arranged on the outer wall of the ball head 1 at an oblique angle, and the oblique angle is 20-25 degrees, and the suspension plate 2 The front is a triangle with a triangular arc transition, and one corner of the suspension plate 2 is connected with the ...

Abstract

The invention belongs to the technical field of articles for automobile parts and particularly relates to a hung spherical shell. The hung spherical shell disclosed by the invention comprises a spherical head and a hung board, wherein the spherical head is a cylindrical body and is provided with a pin shaft hole structure which penetrates through the upper and lower end faces of the spherical head, the pin shaft hole structure comprises an upper hole, a middle hole and a lower hole, the middle hole is a cylindrical hole, an arc-shaped bulge is formed on an opposite side of one corner of the hung board through outwardly extending, the arc-shaped bulge and two other corners of the hung board are of arc transition, hanging holes are formed in the arc-shaped bulge and the two other corners of the hung board, and an equilateral triangle is formed through interconnecting center points of the three hanging holes. The hung spherical shell has the advantages that the structure is reasonable, the manufacturing is simple, and the service time can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile parts and appliances, and in particular relates to a suspension spherical shell. Background technique [0002] The spherical shell for automobile is a part of the automobile parts, and it is mainly used to install the ball pin and play a steering role. There is a large difference in material hardness between the spherical shell and the ball pin for automobiles. Long-term frictional contact, especially in poor road conditions and when the vehicle is turning, the ball pin twists and rubs against the spherical shell for automobiles, which will cause abnormal wear of the spherical shell for a long time. The unreasonable design of the spherical shell for automobiles will also cause unreasonable stress on the spherical shells for automobiles. Cracks will appear on the spherical shells for automobiles from the stress concentration, and they will break after long-term movement. Contents of the invent...
