Abstract

The invention discloses a rust-proof bolt for an automobile hub. The rust-proof bolt comprises a bolt head mechanism, a connecting block, a screw mechanism and a fender, the bolt head mechanism and the connecting block below are stamped and riveted through a stamping machine, the connecting block and the screw mechanism below are stamped and riveted through the stamping machine, the screw mechanism comprises a transition section, a first threaded section, a second threaded section and a guide polished rod section, and the fender can be installed on the first threaded section in an up-and-downadjustable manner. According to the rust-proof bolt, the guide polished rod section is arranged below the screw mechanism, vertical stress of the bolt in the fastening process is guaranteed, and the thread slipping rate is reduced; the fender is matched with the connecting block and the screw mechanism, rainwater, mud and the like are prevented from seeping into a screw hole along a gap of a screwor a bolt head, and the service life of the bolt is prolonged; and an inside hexagonal bolt hole is formed in the middle portion of the bolt head mechanism, even though a hexagon bolt head outsides deforms, bolt quick demounting can be carried out through a hexagonal socket still, and the service life of the bolt is prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of wheel hub bolts, in particular to an antirust bolt for an automobile wheel hub. 【Background technique】 [0002] Hub bolts are high-strength bolts that connect the wheels of vehicles. The connection position is the hub unit bearing of the wheel. Generally, miniature vehicles use grade 10.9, and large and medium-sized vehicles use grade 12.9. The structure of hub bolts is generally knurled key gear, thread gear and a cap head, T-shaped head hub bolts Most of them are above grade 8.8, responsible for the large torsion connection between the wheel hub and the axle. In the past, single row tapered roller or ball bearings were mostly used in pairs. With the development of technology, cars have widely used car hub units. [0003] However, during the fastening operation, if the vertical strength of the bolt and the threaded hole cannot be guaranteed, resulting in oblique force, or the operator is inexperienc...
