Description
Technical field
It the utility model is related to technical field of automobile parts, and in particular to a kind of suspension ball with Novel dust cover
Head.
Background technology
Suspension bulb is one of key safety part of automotive suspension, plays a part of connecting control arm and knuckle, such as Fig. 1
It is shown.In vehicle operation, ball stud shaft constantly swings and rotated relative to its housing, therefore bulb internal lubrication fat needs
It is maintained at good state.Ball end dustproof cover is the primary structure for protecting its internal lubrication fat, can if breakage occurs in dust cover
Extraneous dust, muddy water etc. is caused to enter inside bulb, lubricating grease fails and then bulb breaks down and scrapped.To existing suspension
The phenomenon of the failure of bulb is found after being studied, and when ball end dustproof cover is tapped by larger external force accidentally, external force applies thing with preventing
Bellows are squeezed in centre by the hard shell inside dust hood, dust cover is produced cut, so as to cause suspension ball
Head getting up early failure.Such as vehicle every time carry out chassis maintenance when, it is necessary to be fastened to chassis bolt, to brake caliper etc.
Part carries out status checkout, or vehicle when needing to change damper, hub bearing, the other parts such as power transmission shaft, it is necessary to disassemble
Connection between bulb and knuckle.Nearby part is more, space is small for suspension bulb, when being maintained or tear down operations, behaviour
Make instrument easily to collide with to dust cover generation, if dynamics is slightly larger accidentally, instrument then easily racks dust cover with hard shell.Therefore,
It is necessary to propose a kind of suspension bulb with Novel dust cover, makes it that there is self-protection effect in detachable maintaining, improves
The maintenanceability of suspension bulb, reduce decreasing failure rate.
Utility model content
A kind of the defects of the purpose of this utility model is aiming at prior art, there is provided suspension ball with Novel dust cover
Head.
The technical solution adopted in the utility model is：Including housing, the ball seat being arranged in housing, it is arranged in ball seat
Ball pin, for the ball pin with being provided with dust cover outside housing junction, the dust cover is interior to be provided with dust cover protection ring, described dust-proof
Cover protection ring is and Nian Jie with housing upper surface between dust cover and housing.
Further preferred structure, the dust cover protection ring on the inside of dust cover with being fixedly connected.
Further preferred structure, the dust cover protection ring are cirque structure.
Further preferred structure, the dust cover lower edge are installed in the annular groove of housing.
Further preferred structure, the lower spherical of the ball pin are forced upward into enclosure interior from housing lower end.
Further preferred structure, in addition to bottom plate, the bottom plate are forced upward into housing from housing lower end, under the housing
End margin rotation rivet clasp determines bottom plate, and ball pin and ball seat are sealed.
Further preferred structure, in addition to spring coil, the spring coil by dust cover banding in the annular groove of housing, will in
Portion's sealing structure.
The utility model is soft due to being provided with the high dust cover protection ring of pliability between dust cover and hard shell
Degree is high, and good buffering effect can be produced to impact, can effectively avoid bulb caused by when being tapped by larger external force
Dust cover is damaged, it is ensured that is not extruded when dust cover is tapped by external force by hard material directly, can effectively prevent cut
Generation, improve the service life of bulb.
Brief description of the drawings
Fig. 1 is the application schematic diagram of suspension bulb；
Fig. 2 is the suspension bulb schematic diagram with Novel dust cover；
Fig. 3 is integral type dust cover protection ring schematic diagram；
Fig. 4 is Split dustproof cover protection ring schematic diagram；
Fig. 5 is body diagram.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to be well understood
The utility model, but they do not form to the utility model and limited.
With reference to figure 1,8 be knuckle in figure, and 9 be suspension bulb, and 10 be control arm.
With reference to figure 2, a kind of suspension bulb with Novel dust cover of the present embodiment, it is by ball pin 1, dust cover 2, dust-proof
Cover protection ring 3, spring coil 4, housing 5, ball seat 6, bottom plate 7 form.
The dust cover protection ring 3 of the present embodiment is divided to for integral type and split type two kinds.Integral type protection ring collects with dust cover 2
Into together, for integrated form at 2 inner side of dust cover, the section of dust cover protection ring 3 is warp architecture, itself and the inwall of dust cover 2
Between form a groove 3.1 (shown in Fig. 3) for accommodating housing 5 upper surface, split type protection ring is single circular rings (Fig. 4
It is shown).The lower spherical of ball pin 1 is assembled into one with ball seat 6, inside the lower end of housing 5 press-in housing 5.Bottom plate 7 is from housing 5
Lower end is pressed into housing 5, and the lower edge of housing 5 rotation rivet clasp determines bottom plate 7, ball pin 1 and ball seat 6 are sealed.Dust cover 2 passes through ball pin 1
Top axis body install downwards, dust cover protection ring 3 is between dust cover 2 and housing 5, the upper surface 5-2 of housing 5 and protection ring
3 are bonded as one.The lower edge of dust cover 2 is installed in the annular groove 5-1 of housing 5, spring coil 4 by its banding housing 5 ring
In shape groove 5-1, internal structure is sealed.
In such scheme, dust cover protection ring 3 is provided between dust cover 2 and hard shell 5, it is ensured that dust cover 2
Do not extruded when being tapped by external force by hard material directly, can effectively prevent the generation of cut, that improves bulb uses the longevity
Life.
With reference to figure 3, Fig. 4, the integral type protection ring of dust cover 2, single split type protection ring, this reality are respectively integrated in
It is high to apply the pliability of protection ring 3 of example, good buffering effect can be produced to impact.
With reference to figure 5, the annular groove 5-1 of housing 5 is the interface with dust cover 2, and upper surface 5-2 is and dust cover protection ring 3
Bonding plane.
The content that this specification is not described in detail belongs to prior art known to professional and technical personnel in the field.
