Abstract
The utility model relates to a wheel hub lightweight technical field especially relates to lightweight integral type wheel hub, and its barrel tip at current wheel hub directly processes out the ring gear, and the below processing of ring gear subtracts heavy fabrication hole, has following beneficial effect: 1. reduced wheel hub, ring gear and processed respectively, then the process of assembly, 2, the ring gear is direct to be processed on wheel hub, guarantees tolerance such as axiality between the two easily, is transition fit between 3, current ring gear and the wheel hub, need heat during the ring gear installation, the utility model discloses because need not the installation, so the ring gear need not heat, 4, wheel hub ring gear integration, reprocessing subtracts heavy fabrication hole can alleviate the holistic weight of wheel hub ring gear to reduce the automobile energy consumption.
Description
Technical Field
The utility model relates to a wheel hub lightweight technical field especially relates to lightweight integral type wheel hub.
Background
The automobile is light in weight, and has a great effect on energy conservation and emission reduction, wherein the wheel hub influences the weight of the wheel to a great extent, and the wheel with larger weight can increase the energy consumption of the automobile no matter acceleration or deceleration, so the light in weight is carried out on the wheel hub, and the automobile is an important direction for the light in weight.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide not enough to prior art, and provide lightweight integral type wheel hub, it reduces production processes to wheel hub tip ring gear and wheel hub integration, reduces the cost and improves, carries out the fretwork to wheel hub simultaneously and handles, reduces the whole weight of wheel hub.
The utility model provides a technical scheme that its technical problem adopted is: lightweight integral type wheel hub, it adopts the integral type casting to be T shape, including ring flange and barrel, the tip of barrel processes out the ring gear, the barrel is provided with the weight reduction fabrication hole.
Further, the tooth surface of the gear ring is perpendicular to the axis of the cylinder.
Furthermore, the weight-reducing process holes comprise a plurality of rectangular holes, and the weight-reducing process holes are uniformly distributed along the circumferential direction of the cylinder body.
Furthermore, the weight-reducing fabrication hole is arranged on the oil seal mounting seat at the end part of the cylinder body, the distance between the weight-reducing fabrication hole and the root part of the gear ring is more than 2.5mm, and the weight-reducing fabrication hole axially extends to the bearing mounting seat adjacent to the oil seal mounting seat along the cylinder body.
The beneficial effects of the utility model are that: lightweight integral type wheel hub, its cylinder end at current wheel hub directly processes out the ring gear to the below processing of ring gear subtracts heavy fabrication hole, has following beneficial effect:
1. reduced wheel hub, ring gear and processed respectively, then the process of assembly, 2, the ring gear is direct to be processed on wheel hub, guarantees tolerance such as axiality between the two easily, is transition fit between 3, current ring gear and the wheel hub, need heat during the ring gear installation, the utility model discloses because need not the installation, so the ring gear need not heat, 4, wheel hub ring gear integration, reprocessing subtracts heavy fabrication hole can alleviate the holistic weight of wheel hub ring gear to reduce the automobile energy consumption.
Drawings
Fig. 1 is a perspective view of a lightweight integrated wheel hub according to the present invention.
Description of reference numerals:
1-flange plate, 2-cylinder, 3-gear ring, 4-weight-reducing fabrication hole.
Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the lightweight integrated hub of the present embodiment is integrally cast to be T-shaped, and includes a flange 1 and a barrel 2, a gear ring 3 is machined at an end of the barrel 2, and the barrel 2 is provided with a weight-reduction process hole 4.
In the embodiment, the gear ring 3 does not need to be additionally processed and then is reheated to be in transition fit with the hub, but the gear ring 3 is directly processed on the existing hub, so that the weight of the existing gear ring 3 is directly reduced; the gear ring 3 is directly machined on the hub, assembly is not needed, working procedures can be saved, and the size precision of the gear ring 3 is easily ensured.
The stress of the gear ring 3 is small in practical use, so eight weight-reducing fabrication holes 4 are machined in the barrel 2 below the gear ring 3 in the embodiment. The gear ring 3 and the weight-reducing technical hole 4 are arranged at an oil seal mounting seat at the end part of the hub, the distance from the weight-reducing technical hole 4 to the root part of the gear ring 3 is not less than 2.5mm, and the weight-reducing technical hole 4 axially extends to a bearing mounting seat adjacent to the oil seal mounting seat along the cylinder body 2, so that the structural strength of the hub is not influenced.
It should be finally noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit the scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention.
