Description

High efficiency automobile back wheel knuckle bulb
Technical field
A kind of knuckle is the utility model is related to, more particularly, to a kind of high efficiency automobile back wheel knuckle bulb.
Background technology
Knuckle is one of major part on steering axle of automobile, can make vehicle steadily traveling and sensitive transmission traveling side To the function of knuckle is subject to automotive front load, supports and drives front-wheel to be rotated around stub and make motor turning.In automobile Under transport condition, it subjects changeable shock loading, it is therefore desirable to which it has very high intensity.Chinese patent discloses one Kind returns the bulb type knuckle of positive structure with both-end(Authorization Notice No.:CN205801231U), mainly include knuckle body, One steel bushing is installed by way of interference fit, the center of steel bushing is provided with one in the lower swing arm connecting hole of knuckle body The circular hole set along lower swing arm connecting hole axis direction, circular hole middle part of sliding channel are provided with the deep-slotted chip breaker of a circle indent, and circular hole is located at The internal diameter that internal diameter above deep-slotted chip breaker is located at than circular hole below deep-slotted chip breaker is big;Ball stud, the ball of ball stud are equipped with deep-slotted chip breaker Head is in deep-slotted chip breaker, and the tapered shaft of ball stud is located at below deep-slotted chip breaker, and the upper end of ball stud is provided with one section of tailing axle;Steel bushing it is upper End face is provided with a ring annular groove, and the inwall of annular groove and the inner arm of circular hole are coplanar, and a circle elastic ring is placed with annular groove, annular The upper surface of groove has been bolted end cap, and the center of end cap is provided with the through hole for adapting to tailing axle;Covered on the tapered shaft of ball stud There is baffle ring, a circle elastic pressuring clamping device is additionally provided with ball stud, the upper end of elastic pressuring clamping device is pressed on steel bushing, and lower end is pressed in gear On ring;The lower surface of steel bushing is provided with a circle neck;The upper end of elastic pressuring clamping device is stuck in neck;Elastic pressuring clamping device is taper Stage clip;Elastic pressuring clamping device is the elastic steel protective case with annular corrugated side.But this knuckle dust cover holds Easy to fall off, dust easily invades, and bulb greasy property used is poor, and installation positioning is more inaccurate, and intensity is poor, and is driven Efficiency is poor.
Utility model content
The utility model is to provide a kind of high efficiency automobile back wheel knuckle bulb, and it mainly solves prior art and deposited Knuckle dust cover easily come off, dust easily invades, and bulb greasy property used is poor, and installation positioning is less smart Really, intensity is poor, and the technical problem of the poor grade of transmission efficiency.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals:
High efficiency automobile back wheel knuckle bulb of the present utility model, including spherical shell, described spherical shell is interior to be provided with ball pin, ball The middle part of pin is provided with sphere, and ball seat is provided between sphere and spherical shell, and ball seat lower end is provided with block, and the both ends of spherical shell are provided with neck, Dust cover is embedded with neck, dust cover is fixed by collar, the outwardly formation circular arc in middle part of dust cover, in dust cover Portion forms the inner chamber that section is dome-type.Dust cover is inlaid in mounting groove so that installation is more close.Dust cover is arranged to half Ball-type, the air amount of storage in such dust cover is larger, and dust cover when in use, can be such that the pressure inside and outside dust cover protects all the time Hold unanimously, buffering leeway is larger, can so ensure that dust cover will not fall off.
Preferably, the upper end of described ball seat is provided with oiling chamber.Oiling intracavitary grease up, can cause whole ball Head keeps lubrication.
Preferably, leave extension chamber between the inner side at described ball seat both ends and sphere.Can by extension chamber The both ends of ball seat after expanded by heating there is certain space can extend, and ensure that ball seat does not interfere with sphere.
Preferably, the inner surface of described ball pin is provided with serrated slot, it is embedded with serrated slot and strengthens alloy-layer.By adding Strong alloy-layer can strengthen the intensity of ball pin when in use, and it can be made of commercially available wear-resisting high-strength degree alloy to strengthen alloy-layer.
Preferably, it is designed with knurling layer on the both ends end face of described ball pin.Installed by knurling layer ball pin Shi Dingwei is more accurate, adds frictional force, ensures operating efficiency.
Therefore, the dust cover of the present utility model using dome-type causes dust cover external and internal pressure to be consistent, dust cover Difficult for drop-off, dust is not easy to invade, and lubricity is higher, and installation positioning is more accurate, and intensity is higher, and transmission efficiency is higher, structure Simply, rationally.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is Fig. 1 overlooking the structure diagram.
Parts, position and numbering in figure:Spherical shell 1, ball pin 2, sphere 3, ball seat 4, block 5, neck 6, dust cover 7, card Circle 8, inner chamber 9, oiling chamber 10, extension chamber 11, serrated slot 12, reinforcement alloy-layer 13, knurling layer 14.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment:The high efficiency automobile back wheel knuckle bulb of this example, as shown in Figure 1, Figure 2, including spherical shell 1, it is provided with spherical shell Ball pin 2, the middle part of ball pin are provided with sphere 3, are provided with ball seat 4 between sphere and spherical shell, and ball seat lower end is provided with block 5, and the two of spherical shell End is provided with neck 6, is embedded with dust cover 7 in neck, dust cover is fixed by collar 8, the outwardly formation in middle part of dust cover Circular arc, dust cover are internally formed the inner chamber 9 that section is dome-type.The upper end of ball seat is provided with oiling chamber 10.Ball seat both ends it is interior Extension chamber 11 is left between side and sphere.The inner surface of ball pin is provided with serrated slot 12, is embedded with serrated slot and strengthens alloy-layer 13. Knurling layer 14 is designed with the both ends end face of ball pin.
In use, the utility model is encased in the knuckle of automobile back wheel.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to This, any those skilled in the art in field of the present utility model, all cover in this practicality newly by the change or modification made Among the scope of the claims of type.
