Description
Technical field
The invention belongs to technical field of automobile parts, are related to a kind of ball pin assembly.
Background technique
Effect of the ball head of suspension arm of automobile in suspension is the transmitting of power, and the service life of suspension arm is sizable
The use of bulb is depended in degree, and the perfect lubrication between ball pin and ball seat is then the basic item for guaranteeing bulb normal use
Part.Currently, ball-stud socket in the prior art is typically all an integral ring-shaped plastic sheath, ball pin is packed into the two synthesis after ball seat
The cushion performance of close-fitting ball-joint, this ball-stud socket is poor, and then directly affects the service life of suspension arm, and ball pin has
Ball pin shell, connection structure complexity is cumbersome, outer dimension is larger, and is unfavorable for that outer note grease structure is arranged.And setting exists
Sheath on the outside of ball pin is easy to fall off, and structural stability is poor.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, propose a kind of reasonable in design, stable
The good ball pin assembly of property.
Object of the invention can be realized by the following technical scheme:
This ball pin assembly, including ball pin and mounting base, the ball pin have bulb and the body of rod, have in the mounting base and use
In the mounting groove of installation bulb, the mounting base is equipped with the cover board for preventing bulb from falling off out of mounting groove, feature
It is, the buffer layer for enveloping bulb is equipped in the mounting groove, and the lateral surface of the buffer layer fits in the interior of mounting groove
Side is connected with sheath by fixed structure between the body of rod and mounting base.
In above-mentioned ball pin assembly, the fixed structure includes that gear on the body of rod along two and is set to along one, gear
It keeping off along one and keeps off retaining ring one between two, the gear is formed with annular groove along one and gear between two, and the one of the sheath
End is fixed on gear along one and gear in annular groove between two by retaining ring one.
In above-mentioned ball pin assembly, the fixed structure further includes the annular groove being set on the outside of mounting base and is located at
The other end of retaining ring two at annular groove, the sheath is fixed in annular groove by retaining ring two.
In above-mentioned ball pin assembly, the bottom of the mounting groove is equipped with bolster, and the bulb is resisted against the buffering
On part.
In above-mentioned ball pin assembly, the bottom of the mounting groove has the layer hole for installing bolster, and above-mentioned is slow
Stamping is mounted in this layer of hole, and the side of the bolster is resisted against the bottom in layer hole, and the other side is resisted against on bulb.
In above-mentioned ball pin assembly, the bolster far from the side of bulb have protrusion wave-shaped.Into
One step improves cushion performance.
Compared with prior art, this ball pin assembly has the advantage that
Reasonable in design, one end of sheath is fixed on gear along one and gear in annular groove between two by retaining ring one, retaining ring two
The other end of sheath is fixed in annular groove, sheath will not fall off, and buffer layer and bolster are arranged in mounting groove, can mention
High cushion performance.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of preferred embodiment provided by the invention.
In figure, 1, mounting base；21, bulb；22, the body of rod；3, cover board；4, buffer layer；5, sheath；61, gear is along one；62, it keeps off
Along two；63, retaining ring one；64, annular groove；65, retaining ring two；7, bolster；71, raised.
Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Ball pin assembly as shown in Figure 1, including ball pin and mounting base 1, ball pin have bulb 21 and the body of rod 22, mounting base 1
The interior mounting groove having for installing bulb 21, mounting base 1 are equipped with the cover board for preventing bulb 21 from falling off out of mounting groove
3.As shown in Figure 1, being equipped with the buffer layer 4 for enveloping bulb 21 in mounting groove, the lateral surface of buffer layer 4 fits in the interior of mounting groove
Side is connected with sheath 5 by fixed structure between the body of rod 22 and mounting base 1.
As shown in Figure 1, fixed structure include gear on the body of rod 22 along one 61, gear along 2 62 and be set to gear along 1 with
The retaining ring 1 between 2 62 is kept off, gear is formed with annular groove along one 61 and gear between 2 62, and one end of sheath 5 passes through retaining ring
One 63 are fixed on gear along one 61 and gear in annular groove between 2 62.
As shown in Figure 1, the fixed structure further includes set on the annular groove 64 in 1 outside of mounting base and positioned at annular groove 64
The other end of the retaining ring 2 65 at place, sheath 5 is fixed in annular groove 64 by retaining ring 2 65.
The bottom of mounting groove is equipped with bolster 7, and bulb 21 is resisted against on the bolster 7.Specifically, as shown in Figure 1, pacifying
