Problems solved by technology
[0002] The joint and the ball hinge assembly are important parts in the steering system of the automobile. The ball seat is a plastic part, and the ball seat is assembled in the ball seat cover. The existing single ball seat has the following disadvantages: 1. The ball seat with multiple ribs It is easy to warp and deform during the demoulding process; 2. The size of the spherical cavity is unstable; 3. It is difficult to control the height of the center of the ball; 4. The oil fluidity is poor

Embodiment Construction
[0018] Such as Figure 1 ~ Figure 2 A ball seat for an automobile steering system is shown, including a ball seat body, the inner spherical surface of the ball seat body is provided with a horizontal oil groove 1 arranged along the radial direction of the ball seat, and a plurality of longitudinal oil grooves 2 arranged along the axial direction of the ball seat .
[0019] The top of the outer spherical surface of the ball seat body is provided with a draft 3. The demoulding slope is 9°-11°, and can be 10°. The outer spherical surface of the ball seat body is transitionally fitted with the ball seat sleeve. The spherical tolerance of the outer spherical surface of the ball seat is within 0.1mm, and the surface roughness Ra value is generally 1.6-0.2μm. The wall thickness of the ball seat body gradually increases from the top to the bottom, and the wall thickness is determined according to the difference between the product hole size and the ball pin size. The inner spherica...

Abstract
The invention discloses a ball seat for an automobile steering system. The ball seat comprises a ball seat body, wherein a transverse oil groove arranged along the radial direction of the ball seat and a plurality of longitudinal oil grooves arranged along the axial direction of the ball seat are formed in the inner spherical surface of the ball seat body. With the structure, the ball seat has the following advantages: firstly, a single ball seat structure which is simple, easy to assemble and simple in manufacturing technology, can improve the comprehensive performance of product is adopted, and the problems that plastic ball seats are easily deformed, are untight and loosened in contact during the assembling process can be solved; secondly, the ball seat is good in dimensional stability, is not easily deformed, and is good in flowability of oil inside the ball seat, and thus the extrusion force and pulling force of a ball pin are improved, and the radial and axial displacement of ball joints are reduced.
Description
technical field [0001] The invention relates to the technical field of an automobile steering system, in particular to a ball seat for an automobile steering system. Background technique [0002] The joint and the ball hinge assembly are important parts in the steering system of the automobile. The ball seat is a plastic part, and the ball seat is assembled in the ball seat cover. The existing single ball seat has the following disadvantages: 1. The ball seat with multiple ribs It is easy to warp and deform during the demoulding process; 2. The size of the spherical cavity is unstable; 3. It is difficult to control the height of the center of the ball; 4. The fluidity of the grease is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ball seat for an automobile steering system that is not easily deformed during the demoulding process and improves the fluidity of grease. [0004] In order to solve the above...
