Description

A kind of Hub assembly

Technical field

The utility model relates to technical field of automobile parts, is specially a kind of Hub assembly.

Background technology

At present, Automobile Service personnel mostly utilize wind big gun to carry out degree of tightness to load and unload the tire of automobile to nut, comparatively convenient and swift during use, but, the tightness that each nut is twisted is only sensation with Automobile Service personnel or experience, cause the tightness of each nut different, and then make the location of wheel nave not accurate enough.Meanwhile, automobile is in the process travelled, and tire usually can be poked by nail, and so, the tire pressure of this tire is just on the low side, and traditional wheel nave because bearing force is not enough, easily causes wheel nave to be out of shape when tire pressure is on the low side.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide one to make each nut tightness adjusting degree Hub assembly very nearly the same, on-deformable.

For achieving the above object, the utility model provides following technical scheme: a kind of Hub assembly, comprise hub body, bracing ring is connected with in described hub body, bracing ring comprises inner ring and outer ring, inner ring is connected with curved circle of arc tension force of outer ring by ring-type, the center of inner ring is provided with axis hole, described axis hole edge is provided with the first brace panel of ring-type, inner ring is evenly equipped with several several knock holees centered by axis hole, the edge of knock hole is provided with the second brace panel of ring-type, each second brace panel welds with the first brace panel respectively, the radiating part that described outer ring comprises connecting portion and is connected with connecting portion, on radiating part, annular array has several louvres, the line of centers of louvre is crossing with the line of centers of axis hole, and formed sharp angle is 25 degree of-30 degree.

Further, the inside face of described hub body welds with the outside face of connecting portion.

Further, described knock hole is round table-like, and the aperture place of knock hole is outward extended with nest.

Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: the 1. connecting portion on outer ring and hub body are by welding, and inner ring is fixed on brake disc by connecting elements such as nuts when mounted, inner ring is connected with curved circle of arc tension force of outer ring by ring-type, the curved circle of arc tension force can be respectively outer ring and inner ring provides tension force, actv. supporting wheel hub body, actv. prevents hub body from the generation of local deformation occurring when tire pressure is not enough.2. automobile is in operational process, wheel nave is because constantly brake and continuous rotation can produce a large amount of heats, if heat sheds not in time, easily wear and tear causing the junction of hub body and axletree and be out of shape, therefore, the radiating part comprising connecting portion in outer ring and be connected with connecting portion, on radiating part, annular array has several louvres, the line of centers of louvre is crossing with the line of centers of axis hole, and formed sharp angle is 25 degree of-30 degree, wind can be blown into from all angles, and actv. opens the effect of cooling.3. be outward extended with nest at the aperture place of knock hole, nest actv. plays the effect of location, when use wind big gun carries out fastening nut, and wheel nave is fixed on the reaction plate of automobile, reaction plate is provided with the positioning groove with nest adaptation, when nest all stretches into the reaction plate for fixing vehicle wheel wheel hub, utilize the positioning groove of nest laminating reaction plate, so now, the nut at this place is in tight condition, and then remaining nut is positioned, make the degree of each nut screwing clamping very nearly the same, actv. prevents wheel nave from locating inaccurate and causing the phenomenon of beat to occur.

Fig. 2 is cross-sectional schematic of the present utility model.

Fig. 3 is the G portion enlarged diagram of Fig. 2.

Detailed description of the invention

With reference to Fig. 1-Fig. 3, the utility model is described further.

A kind of Hub assembly, comprise hub body 1, bracing ring 2 is connected with in described hub body 1, bracing ring 2 comprises inner ring 21 and outer ring 22, inner ring 21 is connected by the curved circle 23 of the arc tension force of ring-type with outer ring 22, the center of inner ring 21 is provided with axis hole 211, described axis hole 211 edge is provided with the first brace panel 212 of ring-type, inner ring 21 is evenly equipped with several several knock holees 213 centered by axis hole 211, the edge of knock hole 213 is provided with the second brace panel 214 of ring-type, each second brace panel 214 welds with the first brace panel 212 respectively, the radiating part 222 that described outer ring 22 comprises connecting portion 221 and is connected with connecting portion 221, on radiating part 222, annular array has several louvres 2221, the line of centers of louvre 2221 is crossing with the line of centers of axis hole 211, and formed sharp angle is 25 degree of-30 degree.

Connecting portion 221 on outer ring 22 and hub body 1 are by welding, and inner ring 21 is fixed on brake disc by connecting elements such as nuts when mounted, inner ring 21 is connected by the curved circle 23 of the arc tension force of ring-type with outer ring 22, the curved circle 23 of arc tension force can be respectively outer ring 22 and inner ring 21 provides tension force, actv. supporting wheel hub body 1, actv. prevents hub body 1 from the generation of local deformation occurring when tire pressure is not enough.

Automobile is in operational process, wheel nave is because constantly brake and continuous rotation can produce a large amount of heats, if heat sheds not in time, easily is worn and torn and be out of shape in the junction causing hub body 1 with axletree, therefore, the radiating part 222 comprising connecting portion 221 in outer ring 22 and be connected with connecting portion 221, on radiating part 222, annular array has several louvres 2221, the line of centers of louvre 2221 is crossing with the line of centers of axis hole 211, and formed sharp angle is 25 degree of-30 degree, wind can be blown into from all angles, and actv. opens the effect of cooling.

Bracing ring 2 is that die casting forms, the internal stress of the bracing ring 2 after die casting itself reduces, moreover on bracing ring 2, offer axis hole 211 and knock hole 213 again, its internal stress is just lower, therefore, axis hole 211 edge is provided with the first brace panel 212 of ring-type, the edge of knock hole 213 is provided with the second brace panel 214 of ring-type, each second brace panel 214 welds with the first brace panel 212 respectively, makes it be linked to be an entirety, effectively raises the structural strength of bracing ring 2.

Further, the inside face of described hub body 1 welds with the outside face of connecting portion 221.

Further, described knock hole 213 is in round table-like, and the aperture place of knock hole 213 is outward extended with nest 215.

Nest 215 is outward extended with at the aperture place of knock hole 213, nest 215 actv. plays the effect of location, when use wind big gun carries out fastening nut, and wheel nave is fixed on the reaction plate of automobile, reaction plate is provided with the positioning groove with nest 215 adaptation, when nest 215 all stretches into the reaction plate for fixing vehicle wheel wheel hub, nest 215 is utilized to fit the positioning groove of reaction plate, so now, the nut at this place is in tight condition, and then remaining nut is positioned, make the degree of each nut screwing clamping very nearly the same, actv. prevents wheel nave from locating inaccurate and causing the phenomenon of beat to occur.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
