Abstract
The invention relates to a technology for improving automobile parts, and discloses an aluminum alloy hub with antiskid bolt holes. The aluminum alloy hub is provided with a hub body, wherein at least four bolt holes are formed in a mounting hub of the hub body; each bolt hole consists of two sections, namely a cylindrical hole and a taper hole. The aluminum alloy hub is characterized in that antiskid knurls are formed on the surfaces of the taper holes of the bolt holes in a rolling way. According to the aluminum alloy hub, the problems of potential safety hazards in driving due to the facts of bolt hole fracture and loosening caused probably by insufficient strength and poor antiskid performance of the bolt holes in a conventional aluminum alloy hub are solved; the aluminum alloy hub is applied to the improvement of various types of aluminum alloy hubs.
Description
Technical field
The present invention relates to the improvement technology of auto parts and components, especially a kind of Antisliding bolt hole aluminium alloy wheel hub.
Background technology
Wheel hub is one of main motion parts of automobile, it is to be arranged on axle drive shaft by bolted, therefore on the installation hub of wheel hub, generally have at least four bolts hole, conventionally bolt hole is made up of two sections of cylindrical hole and taper holes, and the cap head of bolt is generally conical suface and is fitted in taper hole.In the prior art, the internal face of the bolt hole on wheel hub is light face, does not possess and strengthens and antiskid function; Because wheel hub and bolt are at a high speed and long-term work under rugged environment, and bear very large moment of torsion, therefore bolted is not firm, and long-term work likely occurs breaking loosening, brings hidden danger to traffic safety.
Summary of the invention
Object of the present invention is exactly to solve the problem that bolt on wheel hub may be loosening, and a kind of Antisliding bolt hole aluminium alloy wheel hub is provided.
Concrete scheme of the present invention is: improve for existing aluminium alloy wheel hub, it has hub body, on the installation hub of hub body, have at least four bolts hole, bolt hole is made up of two sections of cylindrical hole and taper holes, it is characterized in that: on the taper hole surface of bolt hole, rolling has anti-skidding annular knurl.
The lip-deep anti-skidding annular knurl of the taper hole of bolt hole described in the present invention is hatching knurling, and annular knurl modulus is 0.8.
The present invention due to the taper hole surface rolling at bolt hole anti-skidding annular knurl, be mated after bolt is installed and possessed antiskid function, greatly reduced the possibility of bolt looseness, thereby improved the reliability of traffic safety.
The present invention is simple in structure, and improving cost is low, and anti-skidding anti-loosening property is good, has improved traffic safety performance.
Brief description of the drawings
Fig. 1 is front view of the present invention;
Fig. 2 is left cutaway view of the present invention;
Fig. 3 is the I place enlarged view in Fig. 2.
In figure: 1-hub body, 2-installs hub, 3-bolt hole, 4-cylindrical hole section, the anti-skidding annular knurl of 5-, 6-taper hole section.
Detailed description of the invention
Referring to Fig. 1,2,3, the present invention has hub body 1, on the installation hub 2 of hub body 1, have four bolts hole 3 (can also be 5,6 even more bolts hole according to different size), bolt hole 3 is made up of 6 two sections of cylindrical hole 4 and taper holes, particularly: on taper hole 6 surfaces of bolt hole 3, rolling has anti-skidding annular knurl 5.
The lip-deep anti-skidding annular knurl 5 of the taper hole of bolt hole 3 described in the present embodiment is hatching knurling, and annular knurl modulus is 0.8.
Claims (2)
