- Assemble the ball joint 1 by covering the 14 and mounting the dust cano 1-5.
- the ball joint 1 connects the connection part (not shown) of the housing 2 to the mounting part of the first mounting member, and furthermore, connects the housing 2 to the mounting part of the first mounting member. In a state where the male screw portion 34 of the first stand 3 is connected to the mounting portion of the second mounting member, and the first mounting member and the second mounting member are connected.
- the ball joint 1 is assembled to form, for example, a suspension system and a steering system of an automobile.
- the ball stand 3 swings with the movement of the mounting portion.
- the end face of the bearing sheet 4 through which the through hole 36 is opened is the flange 1 of the plug 15 of the nozzle 2.
- the bearing seat 4 is not moved, and the ball head 31 is moved to the bearing seat because it is abutted so as to be pressed against the bearing 8.
- the inner surface of the unit 4 is smoothly slid.
- the inner surface of the bearing sheet 4 especially the wedge effect Accordingly, the load can be absorbed by the inclined plate portion 38 of the bearing sheet 4 which comes into contact with the inclined surface portion 24 of the nozing 2. For this reason, the abrasion-resistant material 27 disposed on the inner bottom surface 23 of the housing 2 does not receive an excessively large load.
- the muddy water or the like is damaged. From the damaged part of No.5 There is a danger of intrusion through the ball entry 3, the bearing sheet 4, and the paging 2 through the opening 14 in the housing. Then, the muddy water and the like penetrate and intervene between the ball sand 3, the bearing seat 4 and the housing 2. When the ball 3 swings, it slides with each other.
- the outer surface of the ball head 31 of the ball 3 and the inner surface of the bearing sheet 4 As a result, the inner surface of the soft bearing sheet 4 is likely to be worn out early, and if the bearing sheet 4 is worn, For example, the driver of the vehicle can smoothly mount the mounting part when the ball head 3 of the bearing seat 4 is tied to the ball base 3. No movement is obtained 'A. ii, p8' and replace ball point 1.
- the bearing sheet 4 may be damaged by muddy water and the like. In some cases. Then, when the bearing sheet 4 is broken, the bouncing amount of the ball / sunlight 3 is further increased. Since the body portion 37 of the bearing sheet 4 is not overloaded, the premature wear of the bearing sheet 4 is limited. However, it is likely to occur on the inclined plate part 38 and the bottom plate part 39 where the load is easily applied. Then, when the bearing sheet 4 is broken by premature wear, the ball head 31 of the ball start 3 and the bottom 1 of the housing 2 are broken. The inner surface of 2 faces without bearing sheet 4.
- the bottom of housing 2 Since the wear-resistant material 27 is disposed on the ball 2, the ball head 31 of the ball stud 3 is in contact with the wear-resistant material 27. It faces through such an interval. For this reason, even when muddy water is present between the socket 13 of the nose ring 2 and the ball head 31, the ball sunset 3 is not used. Part of the bottom part 12 of the soft socket 13 wears out early, but after a certain amount of wear, only the hard wear-resistant material 27 becomes the ball head 3 As a result, the wear of the socket 13 is suppressed, and the time until the socket 13 is finally broken is lengthened. If the bearing sheet 4 is damaged and the wear-resistant material 27 is in direct contact with the ball stud 3, the ball stabilizing member 4 is damaged. The amount of rattling of head 3 will be very large, and the driver will be able to clearly recognize the abnormality due to the knock of ball stud 3 Inspections and repairs will be made before the function of the Ruler Sunset 3 is impaired.
- socket 13 is made of an alloy of aluminum alloy, it is compared with a configuration in which the socket is made of steel.
- the ball joint 1 can be reduced in weight and the wear-resistant material 27 is provided, so that early wear of the socket 13 can be suppressed.
- the socket 13 made of an aluminum alloy and the ball head 31 of the ball stage 3 are included, and the inner chamber of the socket 13 is included.
- the inner bottom surface 23 of the bottom portion 12 having a plane facing the opening portion 14 of the nozing 2 and the inner bottom surface portion 23 are brought into contact with each other. Since the wear-resistant material 27 is interposed between the bottom plate portion 39 of the bearing seat 4 and the overload from the outside that is applied to the ball-and-sandboard 3 Is absorbed by the inclined plate portion 38 of the bearing sheet 4 which abuts against the inclined surface portion 24 of the nozing 2, and the wear-resistant material 27 is a comparative load. Because it is located at the inner bottom surface 23 of the nozzle housing 2 and intervenes, the load capacity of the ball joint 1 is reduced. Even if the bearing sheet 4 wears out early, the bearing sheet is likely to wear out early, especially in the direction in which the load acts. The wear-resistant material 27 located between the bottom plate 39 of the housing 4 and the inner bottom surface 23 of the housing 2 prevents premature wear of the socket 13 of the housing 2. It can be prevented efficiently.
- the socket 13 of the nozing 2 is applied to the surface facing the bearing sheet 4, and the wear-resistant material 27 is applied to the bearing sheet 4.
- the recessed part 26 for accommodating and positioning and holding it in contact is provided, so the ball head of the ball Even if stress is applied from the outside, such as when the 3 slides, the concave structure 26 has a simple structure and the abrasion-resistant material 27 is positioned so that it does not move. In this case, the movement of the wear-resistant material 27 can prevent the socket 13 of the bearing sheet 4 and the nodging 2 from being worn early.
- the ball joint 1 used for the suspension system and the steering system of the vehicle was explained, but the toy was used. It can be applied to any type of self-contained fittings such as tools and various machine tools.
- the aluminum alloy constituting the socket 13 the aluminum alloy which flows by the pressurized pressure, and the ball joint 1 has nodging.
- the wear-resistant material 27 is housed in the recess 26 formed in the inner bottom surface 23 of the nozzle 2, but, for example, the inner peripheral surface of the housing 2.
- the entire surface between the outer peripheral surface of the bearing sheet 4 and the outer peripheral surface of the bearing sheet 4 may cause some rails to be easily worn out early due to the load.
- the inclined plate For example, at least a part between the socket 13 and the ball start 3 may be interposed.
- the wear-resistant material 27 was placed in the concave portion 26 and positioned.However, the concave portion 26 was not provided, and the wear-resistant material 27 was positioned in either configuration. You may.
- the socket 13 of the nozzle 2 is not limited to a bottomed cylindrical body having the bottom portion 12 integrally, but the plug 15 is swaged.
- the bottom part 12 of the separate body may be integrally attached and formed into a bottomed cylindrical shape.
- the shape is not limited to a square shape, but may be a square tube shape or a bottomed tube shape.
- the knowsing 2 may form a plug 15 for receiving the bearing sheet 4 integrally with the socket 13. it can .
- an insertion hole is opened on the opposite side to the opening portion 14 to be reduced in diameter, and a separate bottom portion 12 is attached to the insertion hole to close the insertion hole.

For example, it is possible to install female screws to be screwed with this, or to connect them by welding or the like to the part to be mounted without installing these male threads 34 and female threads. You can do it.
- the bearing sheet 4 is described as being formed in a block shape, the ball head 31 may have any shape that can be slidably included. .
- the dust box 15 may be used. It is preferable that the dust canisters 5 are provided to prevent foreign substances such as muddy water from entering, thereby preventing early wear. Possibility of industrial use
