The unique design of the inner rim and the outer rim strengthens the structural strength and reduces the weight, so that a 70kg more heavy-load steel wheel is reduced to 45 kg.
Description
Technical Field
The utility model relates to a wheel technical field especially relates to a high-speed heavy-duty car steel wheel.
Background
Steel wheels of high-speed engineering vehicles, truck cranes, fire fighting vehicles, military off-road vehicles and the like, in particular to heavy-duty wheels with the running speed of more than 80 kilometers per hour and the nominal diameter of 18-24 inches, and the single wheel bearing capacity reaches 6 tons. The existing heavy-duty high-speed wheel is generally divided into an aluminum alloy wheel and a steel wheel. The heavy-duty aluminum alloy wheel is generally divided into two parts. The structural forms of the heavy-duty steel wheel include a split type and a multi-piece type (more than two pieces).
In order to meet the heavy-load requirement, the heavy-load aluminum alloy wheel has a much larger thickness than a light-load wheel, the material consumption is increased and generally reaches over 35kg, and finally high cost is caused; when the structural form is one-piece, the tire is also heavy-duty, and has more layers, so the tire cannot be disassembled and assembled; when the structural form is divided into two, the problem of difficult tire disassembly and assembly is solved, but after the rim is divided into two halves, at least one spoke is added, the material consumption is continuously increased, and the cost is continuously increased; the aluminum alloy has poor impact toughness and high requirement on road conditions, and particularly cannot meet the cross-country working condition.
The heavy-duty steel wheel also cannot adopt a one-piece structure due to tyre installation; existing split and multi-piece constructions typically weigh over 70kg for wheels above 18 inches.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lightweight of special shape and structure is to open heavy load steel wheel, aims at solving heavy load steel wheel structural problem and the great problem of weight.
The utility model discloses a realize like this: a lightweight split heavy-duty steel wheel comprises an outer rim, an inner rim, a hub and a spoke, wherein the inner rim and the spoke are welded and connected to the hub through two welding seams, and the outer rim and the inner rim are connected through bolts and nuts; the contour of the outer rim is formed by connecting a reverse circular arc R2 with a same-direction circular arc R1 and a same-direction circular arc R3, wherein R1 meets the standard requirement, R2 and R3 are designed for increasing the rigidity of the rim, and the arc lengths of R2 and R3 are both less than or equal to 8 mm; the bottom of the inner rim is provided with a groove, and the depth of the groove is 0.5-1.0 time of the thickness of the rim plate; the thickness of the outer rim is 3-4 mm, and the outer rim is made of hot forming steel WHF1300 with the tensile strength larger than 1300 MPa.
