Problems solved by technology
[0007] In addition, although some organizations and individuals have made some designs for the hollowing of cast spokes, due to the use of poorly consistent welding processes at the bolts of the hub, the consistency of the production quality of the hub has been questioned.

Embodiment Construction
[0033] The wheel hub in this case is composed of a rim 1, a spoke 2, and a torque fastener 3.
[0034] The rim 1 is shaped using a known conventional production method.
[0035] Affected by the braking force of the vehicle and the eccentricity of the fixed position of the hub, the spokes of the hub bear complex and variable loads from the axial, radial and circumferential directions. A vertical wall with a necessary width in the axial direction forms an inner wall and an outer wall structure with a necessary width and opposite directions in the approximate circumferential direction of the vertical wall.
[0036] In this regard, the disc-shaped integral plate is used for the spoke 2 to press five inner concave surfaces that radiate towards the edge of the spoke and end in the edge of the spoke according to the areas of the five bolt fixing holes of the hub, and the concave direction faces the direction of the fixing flange of the hub of the axle, forming 5 arc surfaces opening...

The invention discloses a hub structure formed by a steel plate. The hub structure is mainly composed of a rim, a wheel arm and moment fasteners, wherein the wheel arm and the moment fastener are of an embedded hollow structure, and the wheel arm and the rim are of a welding structure. The rim is made of a hot-formed high-strength steel plate in an annealing state according to an existing traditional technology, the wheel arm is made of a hot-formed high-strength steel plate in an annealing state through stamping forming, necessary distances are reserved between the inner walls of spokes of the wheel arm and the center of form of the wheel arm spokes and between the outer walls of the spokes of the wheel arm and the center of form of the wheel arm spokes, in this way, a load-resistant structure which can resist a bending load is formed, and the inertia moment and the static moment of the wheel arm are greatly increased when the moment fasteners are embedded in the wheel arm; the wheel arm and the rim are placed in a shape change control quenching furnace after being welded so that quenching can be conducted, and thus the stress intensity can reach over 1400MPa. A super-light, high-strength and low-cost automobile hub is formed.
Description
technical field [0001] This design relates to the automobile wheel hub system, especially the automobile wheel hub formed by pressing the steel plate. Background technique [0002] At present, medium and high-performance cars in the automotive industry basically use cast aluminum alloy wheels because of the heavy weight of steel wheels. Steel wheels are only used on some low-end cars because of their weight disadvantages and monotonous appearance. Speed-up performance and fuel consumption play a crucial role. With the successful opening of high-performance steel by large iron and steel enterprises, the weight of steel wheels is close to the level of aluminum alloy wheels. Since the largest stress-bearing part of the hub is at the installation part of the hub, the disc-shaped solid structure at the center of the traditional steel hub is affected by the rated load of the hub, so that the weight reduction effect is limited, although some patents have been made in recent years ...
