Novel lightweight automobile hub

Abstract

The invention relates to the technical field of hubs and in particular relates to a novel lightweight automobile hub. Multiple groups of spiral grooves are circumferentially and uniformly formed inside the rim. Under the condition that the own strength of the hub is ensured, multiple groups of spiral grooves are formed inside the rim, so that the own weight of the hub can be lightened, the heat dissipation surface is relatively enlarged after long-term automobile driving while conducting heat from the tire to the hub, and the problems that the larger the size of the traditional hub is, the heavier the hub is and the heat dissipation performance is poor due to a small heat dissipation surface of the rim can be solved. With the adoption of the structure that a transmission frame is arrangedat a central position on the outer side of the hub, by virtue of circumferential drive of a second spring between the transmission frame and the spoke and longitudinal drive of a transmission arm anda first spring, the hub achieves an excellent buffering effect, rigid shock of some grooves to the tire can be relieved, and the problems that sharp jolting of the vehicle body and poor driving comfort are caused after the traditional hub is replaced with a big hub and a flat tire drives on a bumpy road can be solved.

Description

technical field [0001] The invention relates to the technical field of wheel hubs, in particular to a novel lightweight automotive wheel hub. Background technique [0002] At present, many car lovers like to replace the wheels with large wheels after buying a car, not only because of the cool appearance of the large wheels, but also because the large wheels have a larger contact area with the ground than the small wheels and have better grip. The disadvantages of the wheel hub are that the size is too large and the weight is too heavy, so it can only be equipped with flat tires, which reduces the driving comfort. Therefore, it is urgent to develop a wheel hub with light weight and cushioning effect. .

[0003] The technical problem to be solved by the present invention is to provide a new type of lightweight automobile wheel hub in view of the above-mentioned technical deficiencies. The internal circumference of the rim is uniformly provided with multiple sets of spiral grooves, and the strength of the wheel hub itself is ensured. , multiple sets of spiral grooves are set on the inner surface of the rim, which can not only reduce the weight of the wheel itself, but also make the heat dissipation surface relatively large when the tire conducts heat to the wheel after the car has been driving for a long time. The heavier the rim, the smaller the heat dissipation surface of the rim, resulting in poor heat dissipation; the structure with a drive frame at the center of the outside of the hub is adopted, and the second spring is used to drive the drive frame and the spokes in the circumferential direction, and the drive arm and the spokes are driven longitudinally. The first spring drive makes the hub itself have a good cushioning effect, which can slow down the rigid impact of some grooves on the tire, and solve the problem of severe bumps on the body caused by using flat tires to drive on potholes after the traditional hub is replaced with a larger hub. and poor driving comfort
