Abstract
The utility model aims at providing a subtract heavy aluminum alloy wheel hub can effectively reduce wheel hub's weight and cost when guaranteeing wheel hub intensity. The utility model discloses a subtract heavy aluminum alloy wheel hub includes the wheel hub body, and the key lies in the wheel hub body is equipped with at the rim back and the one side that is close the spoke and subtracts the heavy groove, subtract the back in one side and the rim in heavy groove and meet, the opposite side meets with the root of spoke. After the die sinking of the aluminum alloy hub body is completed, the weight reducing grooves are machined on the back surface of the rim in a machining mode, and the positions of the weight reducing grooves are not main supporting points, so that the strength of the hub cannot be greatly reduced after the weight reducing grooves are arranged, but the weight of the hub can be obviously reduced, and the cost is reduced; and has more layering in appearance, and improves the aesthetic degree of the hub.
Description
Technical Field
The utility model belongs to the technical field of automobile design and manufacturing, concretely relates to automobile wheel hub structure.
background
The aluminum alloy wheel hub has light weight, higher impact resistance, tensile strength, heat power and other strength than that of a steel wheel hub, is beneficial to the light weight of an automobile, thereby reducing the oil consumption, has the heat conduction coefficient of 3 times that of steel, has good heat dissipation effect, can keep the tire at proper temperature when running for a long distance at high speed, ensures that a brake drum and the tire are not easy to age, and reduces the chance of tire burst. Because of the above advantages, aluminum alloy hubs have been increasingly used for medium and high-grade passenger cars. However, the higher price of the aluminum alloy also increases the cost of the whole vehicle.
Disclosure of Invention
The utility model aims at providing a subtract heavy aluminum alloy wheel hub can effectively reduce wheel hub's weight and cost when guaranteeing wheel hub intensity.
the utility model discloses a subtract heavy aluminum alloy wheel hub includes the wheel hub body, and the key lies in the wheel hub body is equipped with at the rim back and the one side that is close the spoke and subtracts the heavy groove, subtract the back in one side and the rim in heavy groove and meet, the opposite side meets with the root of spoke.
After the die sinking of the aluminum alloy hub body is completed, the weight reducing grooves are machined on the back surface of the rim in a machining mode, and the positions of the weight reducing grooves are not main supporting points, so that the strength of the hub cannot be greatly reduced after the weight reducing grooves are arranged, but the weight of the hub can be obviously reduced, and the cost is reduced; and has more layering in appearance, and improves the aesthetic degree of the hub.
The utility model discloses well structure that subtracts the heavy groove has following two kinds:
1. The weight reduction grooves are annular grooves, so that the weight and the cost of the hub can be greatly reduced.
2. The weight-reducing grooves are formed by a plurality of sections of groove bodies at intervals, although the weight-reducing grooves of the structure are inferior to those of the first type in weight-reducing and cost-reducing aspects, the weight-reducing grooves are connected at a plurality of positions between the back face of the rim and the spoke in a crossing mode, and therefore strength can be improved. Further, the interval department of adjacent cell body is located the spoke position department of wheel hub body to the effort that makes the spoke bear can more directly disperse to rim etc. position.
Further, the cross section of the weight-reducing groove is arc-shaped, so that stress concentration is reduced.
The utility model discloses a subtract heavy aluminum alloy wheel hub simple structure, processing convenience can effectively reduce wheel hub's weight and cost when guaranteeing wheel hub intensity, have fine practicality.
Drawings
Fig. 1 is a front view of the weight-reduced aluminum alloy hub of the present invention.
Fig. 2 is a partial sectional view of the weight-reduced aluminum alloy hub of the present invention.
The figures are numbered: 1. a hub body; 2. a rim; 3. a spoke; 4. and a weight reduction groove.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.
Example 1:
This embodiment provides a subtract heavy aluminum alloy wheel hub, can effectively reduce wheel hub's weight and cost when guaranteeing wheel hub intensity.
As shown in fig. 1 and 2, the weight-reducing aluminum alloy wheel hub of the present embodiment includes a wheel hub body 1, wherein the wheel hub body 1 is provided with a weight-reducing groove 4 with an annular structure on a back surface of a rim 2 (i.e. a side of the rim 2 facing a central axial direction of the wheel hub) and a side close to a spoke 3, one side of the weight-reducing groove 4 is connected with the back surface of the rim 2, the other side is connected with a root of the spoke 3, and a cross section of the weight-reducing groove 4 is arc.
after the die sinking of the aluminum alloy hub body 1 is completed, the weight-reducing grooves 4 are machined on the back surface of the rim 2 in a machining mode, and the positions of the weight-reducing grooves 4 are not main supporting points, so that the strength of the hub cannot be greatly reduced after the weight-reducing grooves 4 are arranged, but the weight of the hub can be obviously reduced, and the cost is reduced; and has more layering in appearance, and improves the aesthetic degree of the hub.
Example 2:
Different from the embodiment 1, in the present embodiment, the lightening groove 4 is not a continuous annular structure, but is composed of a plurality of groove bodies with the same length and radian, and the interval of the adjacent groove bodies is located at the position of the spoke 3 of the hub body 1, so that a plurality of positions (namely, the positions between the adjacent groove bodies) between the back surface of the rim 2 and the spoke 3 are connected across the lightening groove 4, so that the acting force borne by the spoke 3 can be more directly dispersed to the positions of the rim 2, and the strength can be improved.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial improvements can be made without modification to the present invention.
