Description
Technical field
The utility model relates to technical field of automobile accessories more particularly to a kind of suspension ball pin assemblies.
Background technique
Suspension ball pin assembly is the key part in the system of independent suspension chassis, its quality directly affects vehicle
The safety of service life, stroke.Suspension ball pin assembly includes shell, ball cup and ball pin, is equipped between shell and ball pin anti-
Dust hood is to form a closed chamber, and dust cover must have good sealing function in any condition, to guarantee that ball pin assembly exists
It can normal use under the adverse circumstances such as muddy water and high and low temperature.
However, dust cover is under the external forces such as assembly or tool, dust cover easily collides with, and leads to breakage, then outer
The silt or water (especially under cross-country operating condition, silt can be more) on boundary will enter inside dust cover, enter back into spherical surface, shadow
The service life of suspension ball pin assembly is rung, and then influences the driving safety of automobile.
Utility model content
The utility model provides a kind of suspension ball pin assembly, and which overcome the prior arts described in background technology not
Foot.
The utility model solve technical solution used by its technical problem first is that:
A kind of suspension ball pin assembly, it includes:
Ball pin, including bulb and pin rod；
Ball cup wraps up the bulb；
Shell, has accommodating space, which accommodates the ball cup and bulb；
PTFE composite self-lubricating liner, is set between bulb and ball cup；
Dust cover, both ends are connect with the shell and pin rod respectively, and it is close that one is formed between the dust cover, shell and ball pin
Closed chamber；
It further include a sealing ring, between the ball cup and bulb in closed chamber.
Among one embodiment: the shell has the joint for being detachably connected with vehicle suspension ontology.
Among one embodiment: the sealing ring is the sealing ring with skeleton.
Among one embodiment: the joint is a body of rod, is externally threaded on the circumferential surface of the body of rod.
Among one embodiment: the central axis of the body of rod and the central axis of ball pin form angle.
Among one embodiment: PTFE composite self-lubricating liner includes two panels, and two panels PTFE composite self-lubricating liner is altogether
The bulb is wrapped up with enclosing.
Among one embodiment: the ball cup, which is equipped with to draw, splits slot, is formed using groove milling technique.
Among one embodiment: further including a cover board, which is fixed on the shell and abuts with the ball cup.
Among one embodiment: the cover board is fixed on the shell using threaded connection.
The technical program compared with the background art, it has the following advantages:
1, by setting sealing ring between the bulb and ball cup in dust cover, double-layer seal is formed in conjunction with dust cover,
It can prevent silt and water from entering spherical surface in the case where seal closure breakage, influence the service life of ball pin and ball pin assembly.
2, the shell has the joint for being detachably connected with vehicle suspension ontology, convenient by the way that joint is arranged
The assembly and disassembly of the ball pin assembly and suspension ontology only need to be by the joint from suspension when the ball pin assembly is needed replacing or repaired
It is removed on ontology, without removing entire suspension transverse arm as the prior art.
3, the ball cup, which is equipped with to draw, splits slot, is formed using groove milling technique, and slot is split in drawing for avoiding being formed using notching process
It squeezes to form protrusion in ball cup inner face, PTFE composite self-lubricating liner is caused to be pasted not strongly, and drawing for notching process formation is split
Slot specification is smaller, is split slot specification using drawing of being formed of groove milling technique and can avoid subsequent difficulty more greatly and draw the problem of splitting.
4, PTFE composite self-lubricating liner is set to the friction pair between bulb and ball cup as bearing, it can be achieved that exempting from
It safeguards self-lubricating function, extends bearing life and bearing reliability.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the schematic cross-sectional view of suspension ball pin assembly described in the present embodiment.
Fig. 2 is the explosive view of suspension ball pin assembly described in the present embodiment.
Fig. 3 is the top view of ball cup described in the present embodiment.
Fig. 4 is the half sectional view of ball cup described in the present embodiment.
Specific embodiment
Please refer to Fig. 1 and Fig. 2, a kind of suspension ball pin assembly, it includes ball pin 10, ball cup 20, shell 30, PTFE compound
Selflubricating liner 40, dust cover 50 and sealing ring 60.
The ball pin 10 includes bulb 11 and pin rod 12；The ball cup 20 wraps up the bulb 11；The shell 30 has receiving
Space 31, the accommodating space 31 accommodate the ball cup 20 and bulb 11；PTFE composite self-lubricating liner 40, is set to bulb 11
Between ball cup 20, as the friction pair between bulb 11 and ball cup 20, in the present embodiment, PTFE composite self-lubricating lining
Pad 40 includes two panels, and two panels PTFE composite self-lubricating liner 40 encloses jointly wraps up the bulb 11；The both ends of the dust cover 50
It is connect respectively with the shell 30 and pin rod 12, and forms a closed chamber 51 between the dust cover 50, shell 30 and ball pin 10；This is close
Seal 60 is set between ball cup 20 and bulb 11 in closed chamber 51, and specifically, which is set in closed chamber 51
Gap inlet between ball cup 20 and bulb 11, to prevent dust or water from entering ball cup 20 and ball from the gap inlet
Between first 11, in the present embodiment, which is the sealing ring with skeleton.
