Abstract
The utility model relates to the improved technology of automobile parts, and discloses an aluminum alloy hub with strengthening and anti-skidding bolt holes. The aluminum alloy hub comprises a hub body. At least four installing holes are formed in an installing hub of the hub body. The aluminum alloy hub is characterized in that a steel sleeve is installed in each installing hole, a bolt hole is formed inside each steel sleeve, each bolt hole is composed of two sections including a cylindrical hole and a conical hole, and an anti-skidding knurl is arranged on the surface of the conical hole of each bolt hole in a rolling mode. The aluminum alloy hub overcomes the defects that a bolt in an existing aluminum alloy hub can be fractured and loosened to bring hidden danger to driving safety due to the fact that bolt holes are poor in strengthening and anti-skidding properties, and the improvement of aluminum alloy hubs of different types is facilitated.
Description
Technical field
The utility model relates to the improvement technology of auto parts and components, the anti-skidding bolt hole aluminium alloy wheel hub of especially a kind of reinforcement.
Background technology
Wheel hub is one of main motion parts of automobile, it is to be installed on the axle drive shaft by bolted, therefore generally have at least four bolts hole on the installation hub of wheel hub, bolt hole is made of for two sections cylindrical hole and taper hole usually, and the cap head of bolt is generally conical suface and is fitted in the taper hole.In the prior art, the internal face of the bolt hole on the wheel hub is the light face, does not possess anti-skidding reinforcement and function; Because wheel hub and bolt are long-term works under high speed and rugged environment, and bear very big moment of torsion, so bolted is not firm, long-term work might occur breaking loosening, and on the other hand, aluminum alloy bolt hole intensity is limited, influence the service life of wheel hub, bring hidden danger to traffic safety.
Summary of the invention
It is limited that the purpose of this utility model will solve the boss bolt hole strength exactly, and the problem that the bolt on it may become flexible provides a kind of reinforcement anti-skidding bolt hole aluminium alloy wheel hub.
Concrete scheme of the present utility model is: improve at existing aluminium alloy wheel hub, it has hub body, on the installation hub of hub body, have at least four mounting holes, it is characterized in that: in each mounting hole, steel bushing is housed, be provided with bolt hole in the steel bushing, bolt hole is made of for two sections cylindrical hole and taper hole, and rolling has anti-skidding annular knurl on the taper hole surface of bolt hole.
The lip-deep anti-skidding annular knurl of the bolt hole of steel bushing described in the utility model taper hole is a hatching knurling, and the annular knurl modulus is 0.8.
The utility model is owing to installed steel bushing additional in hub installing hole, and in the surface rolling of the taper hole of steel bushing bolt hole anti-skidding annular knurl, promptly improved the intensity of hub installing hole, be mated after bolt is installed and possessed antiskid function, reduce the possibility of bolt looseness greatly, thereby improved the reliability of traffic safety.
The utility model is simple in structure, and it is low to improve cost, and anti-skidding anti-loosening property is good, has prolonged wheel hub service life, has improved the traffic safety performance.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is a left cutaway view of the present utility model;
Fig. 3 is the I place enlarged view among Fig. 2.
Among the figure: the 1-hub body, 2-installs hub, 3-mounting hole, 4-cylindrical hole section, the anti-skidding annular knurl of 5-, 6-taper hole section, 7-steel bushing.
The specific embodiment
Referring to Fig. 1,2,3, the utlity model has hub body 1, on the installation hub 2 of hub body 1, have four mounting holes 3 (can also be 5,6 even more a plurality of mounting hole according to different size), particularly: in each mounting hole 3, steel bushing 7 is housed, be provided with bolt hole in the steel bushing 7, bolt hole is made of cylindrical hole section 4 and taper hole section 6, and rolling has anti-skidding annular knurl 5 on the taper hole surface of bolt hole.
The lip-deep anti-skidding annular knurl 5 of the bolt hole of steel bushing described in present embodiment taper hole is a hatching knurling, and the annular knurl modulus is 0.8.
Claims (2)
1. strengthen anti-skidding bolt hole aluminium alloy wheel hub for one kind, has hub body, on the installation hub of hub body, have at least four mounting holes, it is characterized in that: in each mounting hole, steel bushing is housed, be provided with bolt hole in the steel bushing, bolt hole is made of for two sections cylindrical hole and taper hole, and rolling has anti-skidding annular knurl on the taper hole surface of bolt hole.
2. the anti-skidding bolt hole aluminium alloy wheel hub of a kind of reinforcement according to claim 1 is characterized in that: the lip-deep anti-skidding annular knurl of described steel bushing bolt hole taper hole is a hatching knurling, and the annular knurl modulus is 0.8.
