Abstract
The utility model provides a spherical pin with a dustproof sealing ring, belonging to the technical field of automobile fittings. The utility model particularly relates to a spherical pin with a dustproof sealing ring, which comprises a spherical pin and a sealing ring body, and is characterized in that an annular convex block is arranged at the rod part of the spherical pin; an annular groove is arranged at one end of the sealing ring body; the external surface of the annular convex block is wrapped by the annular groove; and a clamping convex block is arranged at the other end of the sealing ring body. In the utility model, the annular convex block is arranged at the rod part of the spherical pin with the dustproof sealing ring; the annular groove is arranged at one end of the sealing ring body; the external surface of the annular convex block is wrapped by the annular groove; therefore, the sealing ring body is firmly fixed on the spherical pin; when the spherical pin swings and generates an axial displacement, the clearance is not generated between the sealing ring and the spherical pin; dusts or impurities outside do not enter the clearance between the spherical pin and a spherical pin lining; and the abrading or jamming phenomenon is avoided, and the normal running and safety of the whole system are ensured.
Description
Technical field
The utility model belongs to the auto parts machinery technical field, is specifically related to a kind of sphere pin of dust-proof seal ring.
Background technique
Automotive track bar is the important accessory of automobile, is arranged in the truck usually, on the back axle, uses in pairs.Track bar is installed on the vehicle frame by the sphere pin, and the sphere pin is installed in the pin joint hole of track bar termination by seal ring.Track bar is mainly used in the settling position that keeps vehicle bridge, overcome Steel Spring Plate simultaneously and can only transmit longitudinal force and lateral force, and can not transmitting tractive power, the drawback of braking force and the corresponding moment of reaction thereof.If poor sealing between pin joint hole on the track bar and the sphere pin, silt or dust very easily enter sphere pin assembly inside, to accelerate its wearing and tearing, and then cause the decreased performance of whole track bar, reduce working life greatly.As shown in Figure 1, at present, the seal ring that most of producer installs in the sphere pin outside is provided with several parallel sealing ditches 1 on the surface of contact of seal ring and sphere pin, when the sphere pin on the track bar is swung generation when moving axially, seal ring can not move together along with the sphere pin, extraneous dust or silt can enter between sphere pin and the sphere pin bush(ing) by sealing ditch 1, cause wearing and tearing or stuck phenomenon, can cause the accident when serious, influence the normal operation and the safety of whole locomotive body.
Summary of the invention
The technical problem that the utility model solved is: design a kind of sphere pin that has dust-proof seal ring, can improve the anti-dust performance of sphere pin.
The technological scheme that its technical problem that will solve the utility model adopts is: design a kind of sphere pin that has dust-proof seal ring, comprise sphere pin and seal ring body, it is characterized in that annular lug being set in the bar portion of sphere pin, at seal ring body one end annular groove is set, annular groove parcel annular lug outer surface; The seal ring body the other end is provided with the chucking projection.
This body section of seal ring is " U " type or " L " type.
The beneficial effect that the utility model had is:
Bar portion at the sphere pin is provided with annular lug, at seal ring body one end annular groove is set, annular groove is wrapped in the annular lug outer surface, like this, the seal ring body will be fixed on the sphere pin firmly, does swing when the sphere pin and produces when moving axially, can not produce the gap between seal ring and the sphere pin, extraneous dust or foreign material can not enter between sphere pin and the sphere pin bush(ing), can not cause wearing and tearing or stuck phenomenon, have guaranteed the normal operation and the safety of whole system.This body section of seal ring is " U " type or " L " type, and seal ring one end is provided with annular groove and links to each other with the sphere pin, and the other end is provided with the chucking projection and is tightened by end cap, even if the sphere pin is done axial motion among a small circle in pin-and-hole, also can not make seal ring displacement or deviates from.
The utility model simplicity of design, easy to use, suitable penetration and promotion and industrialized production.
Description of drawings
Fig. 1 is the structural representation of conventional seals circle;
Fig. 2 is the structural representation of the utility model user mode;
Fig. 3 is the structural representation of the utility model seal ring;
Among the figure: 1. seal ditch, 2. bar portion, 3. seal ring body, 4. lining, 5. annular lug, 6. back-up ring, 7. spheroid, 8. end cap, 9. annular groove, 10. chucking projection.
Embodiment
As shown in the figure, a kind of sphere pin that has dust-proof seal ring described in the utility model, the sphere pin is made up of spheroid 7 and bar portion 2, at spheroid 7 arranged outside linings 4, at bar portion 2 two ends annular lug 5 is set; At seal ring body 3 one ends annular groove 9 is set, annular groove 9 is wrapped in annular lug 5 outer surfaces, and seal ring body 3 the other ends are provided with chucking projection 10, and chucking projection 10 is tightened by end cap 8, seal ring body 3 cross sections are " U " type, and back-up ring 6 is arranged on lining 4 upper ends.
Annular groove on the seal ring body 39 is wrapped in annular lug 5 outer surfaces of bar portion 2 both sides, when vehicle bridge drive sphere pin swing generation moves axially, seal ring is movement therewith also, combine closely between annular groove 9 and the annular lug 5, seamless, extraneous dust or foreign material can not enter into the sphere pin assembly, have played good dustproof effect.And traditional seal ring one end has sealing ditch 1, closes not closely with the sphere keying, is easy to generate the gap.
It is to be noted; above-mentioned mode of execution only is the utility model preferred embodiment; for those skilled in the art, under the prerequisite that meets the utility model working principle, any be equal to or similar replacement all falls in the protection domain of the present utility model.
Claims (3)
1. a sphere pin that has dust-proof seal ring comprises sphere pin and seal ring body, it is characterized in that in the bar portion of sphere pin annular lug being set, and at seal ring body one end annular groove is set, annular groove parcel annular lug outer surface; The seal ring body the other end is provided with the chucking projection.
2. a kind of sphere pin that has dust-proof seal ring according to claim 1 is characterized in that this body section of seal ring is " U " type.
3. a kind of sphere pin that has dust-proof seal ring according to claim 1 is characterized in that this body section of seal ring is " L " type.
