Problems solved by technology

There is a large difference in hardness between the spherical shell of the automotive tie rod and the ball pin. 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 of the automotive tie rod, which will cause abnormalities in the spherical shell of the automotive tie rod for a long time wear and tear
The unreasonable design of the automotive tie rod spherical shell will also make the force of the automotive tie rod spherical shell unreasonable, and the automotive tie rod 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] like figure 1 and figure 2 As shown in the drawing, the tie rod spherical shell includes a ball head 1 and a ball handle 2. The ball head 1 is a cylinder with one side protruding in an arc shape, and the ball head 1 is provided with a concave structure. 3. The concave structure 3 runs through the upper and lower end faces of the ball head 1. The concave structure 3 includes an upper hole 4, a middle hole 5 and a lower hole 6. The middle hole 5 is a cylindrical through hole, the upper hole 4 is a conical hole, and the upper hole 4 is a conical hole. The hole 6 shrinks gradually from top to bottom, the upper end of the upper hole 4 and the upper end surface of the ball head 1 have a circular arc transition, the lower end of the upper hole 4 is the upper end of the middle hole 5, the lower hole 6 is a U-shaped hole, and the lower hole 6 The length is greater than the length of the upper hol...

Abstract

The invention belongs to the technical field of automobile parts, and relates to a drag link ball shell. The drag link ball shell comprises a ball head and a ball handle. The ball head is a cylinder, wherein one side portion of the cylinder protrudes outwards in an arc shape. The ball head is provided with a concave structure which penetrates through the upper end face and the lower end face of the ball head, the concave structure comprises an upper hole, a middle hole and a lower hole, and the length of the lower hole is larger than that of the upper hole. The ball handle comprises a crank and a straight shank, one end of the crank is fixedly connected with the lower side portion of the ball head, the position, located close to the ball head, of the upper portion of one end of the crank is provided with an arc-shaped chute, and the other end of the crank is connected with the straight shank. The crank is provided with an inward concave arc surface and an outward convex arc surface, the radian of the inward concave arc surface ranges from 5 degrees to 10 degrees, the radian of the outward convex arc surface ranges from 2 degrees to 6 degrees, and the crank is provided with an inward concave through hole penetrating through the crank. The drag link ball shell is reasonable in structure, and the service life of the drag link ball shell 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 tie rod spherical shell. Background technique [0002] The tie rod spherical shell for automobile is a part of the automobile parts, mainly used to install the ball pin and play the role of steering. There is a large difference in hardness between the spherical shell of the automotive tie rod and the ball pin. 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 of the automotive tie rod, which will cause abnormalities in the spherical shell of the automotive tie rod for a long time wear and tear. The unreasonable design of the automotive tie rod spherical shell will also make the force of the automotive tie rod spherical shell unreasonable, and the automotive tie rod spherical shell will crack from the stress concentration, and it will brea...
