Embodiment Construction

[0017] From figure 1 , Figure 4 It can be seen from the figure that a lightweight light alloy wheel, the main body of the wheel is processed by light alloy, and the structure of the main body is basically the same as that of the existing wheel, consisting of a rim 1, a wheel disc 2 and a hub 3. The rim 1 is a part of the peripheral edge of the wheel, which is used to install the tire. According to the existing standard, two annular protruding rings 13 and 14 are arranged on the inner side of the rim 1 . The disc 2 , also called the spoke, is the middle part connecting the hub 3 and the rim 1 . The hub portion 3 is the part where the axle is installed at the center of the wheel. It is mounted on the axle tube or steering knuckle through bearings. According to the structure of the wheel, the wheel can be divided into two types: disc type and spoke type. Usually the rim 1 and the wheel disc 2 are made as a whole. The hub 3 is provided with several bolt mounting holes 31 and...

Abstract

The invention relates to a lightweight light-alloy wheel, which consists of a wheel rim, a wheel disc and a hub part. The inside of the wheel rim is provided with two annular convex rings, and a wheel edge part of the wheel rim is provided with a convex annular step. The wall thickness of the wheel rim between the two annular convex rings is reduced by 5 to 20 percent compared with the wall thickness of the wheel rim between the annular step of the wheel rim and the annular convex rings. Because the ultrathin wheel rim is adopted, the weight is effectively lightened on a wheel rim body, and the strength is enhanced. The weight of the wheel adopting the structure can be effectively lightened under the condition of meeting the using safety and reliable performance of the wheel, the oil consumption is effectively reduced, and the acceleration performance and ground attachment performance of a vehicle are improved.

Description

technical field [0001] The invention relates to a wheel, in particular to a lightweight light alloy wheel for vehicles. Background technique [0002] We know that the wheel is one of the safety parts of the assembled vehicle, and its quality is directly related to the safety of human life. The automobile wheel bears the vertical load, lateral force, driving (braking) torque and various stresses generated during the driving process of the vehicle. It is a high-speed rotary motion part, which requires high dimensional accuracy, small unbalance, and supports the tire. The rim is accurate in shape, light in weight, and has certain rigidity, elasticity and fatigue resistance. Therefore, the wheels are required to have sufficient load capacity and speed capacity, good cushioning and air tightness, good uniformity and mass balance, exquisite appearance and decoration, high dimensional accuracy, small quality, low price, easy disassembly and assembly, Good interchangeability etc. ...
