Abstract
The utility model discloses a novel light hub of motor vehicles. The novel light hub comprises a rim and a spoke, wherein the rim is made of dual-phase steel DP540, and the spoke is made of dual-phase steel DP 590. The whole weight of a finished product hub is reduced by 21.1 percent, and meanwhile, the strength and the fatigue resistance of the hub are increased. The safety performance of cars and the fuel economy are increased to a certain extent.
Description
Technical field
The utility model relates to a kind of wheel hub, and especially a kind of novel high-strength steel that adopt are the wheel hub of the power actuated vehicle processed of dual phase steel.
Background technology
Domestic traditional spinning wheel hub adopts common wheel hub special-purpose steel 330CL, 400CL (420CL) to make.Make that intensity is lower, toughness is relatively poor, cost is higher, safety performance is lower.
The utility model content
It is the wheel hub of the power actuated vehicle processed of dual phase steel that the purpose of the utility model provides a kind of novel high-strength steel that adopt.
The utility model adopts following technical scheme:
The novel lightweight wheel hub of a kind of power actuated vehicle comprises wheel rim and spoke, and said wheel rim 1 adopts dual phase steel DP540 to make, and said spoke 2 adopts dual phase steel DP590 to make.
The beneficial effect of the utility model is:
The utility model lightweight wheel hub raw MAT'L adopts novel high-strength steel---dual phase steel, and wherein wheel rim adopts dual phase steel DP540 to make, and spoke adopts dual phase steel DP590 to make.Dual phase steel be meant dead-soft steel or low-carbon alloy steel through the critical section heat treatment or cooling controlling and rolling controlling process and obtain mainly by high strength steel that double carbide (F)+a small amount of (volume fraction＜30%) martensite (M) is formed.The utility model lightweight wheel hub is made raw-material renewal, when making finished product whole wheel hub weight loss of weight 21.1%, has improved the intensity and the fatigue resistance of wheel hub, and vehicle safety performance and fuel economy all are improved to some extent.
Description of drawings
Fig. 1 is the cutaway view of the utility model.
The specific embodiment
According to embodiment the utility model is done further explain below.
As shown in Figure 1, the novel lightweight wheel hub of a kind of power actuated vehicle comprises wheel rim and spoke, and said wheel rim 1 adopts dual phase steel DP540 to make, and said spoke 2 adopts dual phase steel DP590 to make.
The utility model lightweight wheel hub raw MAT'L adopts novel high-strength steel---dual phase steel, and wherein wheel rim adopts dual phase steel DP540 to make, and spoke adopts dual phase steel DP590 to make.Dual phase steel be meant dead-soft steel or low-carbon alloy steel through the critical section heat treatment or cooling controlling and rolling controlling process and obtain mainly by high strength steel that double carbide (F)+a small amount of (volume fraction＜30%) martensite (M) is formed.The utility model lightweight wheel hub is made raw-material renewal, when making finished product whole wheel hub weight loss of weight 21.1%, has improved the intensity and the fatigue resistance of wheel hub, and vehicle safety performance and fuel economy all are improved to some extent.
Obviously, the above-mentioned instance of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
