Integrally-formed hub

Abstract

The invention relates to the technical field of vehicle assembly, in particular to an integrally-formed hub, comprising a hub body, wherein a mounting disc is mounted inside the hub body; a frameworkis fixedly connected between the hub body and the mounting disc; the hub body, the mounting disc and the framework are connected by integrally forming, and a bearing mechanism is mounted on the innerside surface of the mounting disc; and a reinforcing mechanism is arranged at the side end of the bearing mechanism and connected to the side end of the bearing mechanism. The reinforcing mechanism isarranged at the outer end of the bearing mechanism, so that when an axle is connected to the hub body through a bolt piece, the reinforcing mechanism sleeves the exterior of the bolt piece, and meanwhile, a fastener in a sleeving piece is screwed, so that the fastener can abut against the exterior of the bolt piece, the bolt piece is connected to the hub body and the axle more stably; and meanwhile, after the outer part of the hub body is disengaged from a bolt piece connecting nut, the axle is prevented from being directly separated from the hub body, thus improving the driving safety, and guaranteeing normal and stable traveling of a vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to an integrally formed wheel hub. Background technique [0002] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. Also known as rims, steel rims, wheels, and tire bells. There are many types of hubs according to diameter, width, molding method and material; [0003] In the past, most car wheel bearings used single-row tapered roller or ball bearings in pairs. With the development of technology, cars have widely used car hub units. The use range and amount of hub bearing units are increasing day by day, and it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fit the bearing on the wheel shaft and fix it with nuts. Makes car maintenance easier. The third...

Problems solved by technology

[0005] In the traditional installation process of the wheel hub and the axle of the car, the only thing is to set multiple sets of mounting holes inside the wheel hub. By passing the axle through the mounting openings inside the wheel hub, the connecting flange outside the axle is connected to the mounting holes, and the mounting holes are connected by bolts. Fixed connection, the bolt cap of this installation method is usually set on the outside of the wheel hub, which is easy to rub against the outside during the driving process of the car, and the wheel hub and the axle are fixedly connected by bolts. This connection method is single and cannot guarantee the hub Stable connection with the axle
