Abstract
The utility model discloses an automobile steering wheel comprising steel spokes and a steel wheel ring supported by the steel spokes. The automobile steering wheel is characterized in that a covering layer formed by a foaming thermoplastic elastomer is formed on the surface of the steel wheel ring through injection moulding. The automobile steering wheel is manufactured by an injection molding process through adding a foaming agent into plastic materials; and a manufacturing process of the automobile steering wheel comprises the following steps of placing a steel framework formed by the steel spokes and the steel wheel ring supported by the steel spokes into an injection molding mould, injecting plastics into a cavity by an injection molding machine to cover the steel wheel ring, and completing foaming in the injection molding process. All physical chemistry parameters of the obtained steering wheel are better than those of the conventional steering wheel formed by polyurethane foaming.
Description
Technical field
The utility model relates to a kind of vehicle steering.
Background technology
At present, almost all manned vehicles of the whole world all use on metallic framework through polyurethane foam and coat elastic surface, again through the corrosion decorative pattern with spray paint or make decorative means such as corium and process the bearing circle of completion.This type technology is owing to adopt the low pressure foaming technique, and the production cycle needs 6～10 minutes, and in foaming process, has 15～20% waste materials to overflow, and there is nonvolatil pollution in environment.In its production process, volatile quantity is bigger in addition, and production environment is had bigger pollution.More prior is exactly that the polyurethane material of this type bearing circle can't be regenerated, and needs to adopt special processing method to handle.In mechanical properties, the power of holding tightly of this type bearing circle a little less than, non-refractory, inflammable, not wear-resisting, heatproof degree impact is relatively poor.
The utility model content
The utility model technical matters to be solved is to provide a kind of production efficiency height, safety, comfortable health, reclaims convenient, eco-friendly vehicle steering.
The utility model technical matters to be solved can realize through following technical scheme:
A kind of vehicle steering comprises steel-spoke and the steel wheel rim that is supported by steel-spoke, it is characterized in that the clad of foamed thermoplastic elastomers material is arranged in the surperficial injection mo(u)lding of said steel wheel rim.
The vehicle steering of the utility model is compared with the conventional urethane foaming steering wheel, has the following advantages:
1, eliminated that waste material overflows in the traditional handicraft (product 15～20%) to the permanent pollution of environment.
2, significantly reduced the product volatilization smell of environment inside car has been polluted (volatile quantity be merely traditional product 20%).
3, the power of holding tightly of product, resistance to effect of heat, resistance to abrasion, heatproof degree impact are greatly improved.
4, safety factor such as flame resistance greatly promotes
5, vehicle steering of every production only needs 1.5～2 minutes, and production efficiency is 3～4 times of traditional handicraft.
6, productive costs reduces by 15%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the vehicle steering of the utility model comprises steel-spoke 1 and the steel wheel rim 2 that is supported by steel-spoke 1, and the surperficial injection mo(u)lding on steel wheel rim 2 has the clad 3 of foamed thermoplastic elastomers material.
The utility model adds foaming agent in plastic raw materials, the motor turning dish that adopts Shooting Technique to process is as shown in Figure 1.Its manufacturing process is will to be positioned in the injection mould by the steel skeleton that steel-spoke 1 and the steel wheel rim 2 that is supported by steel-spoke 1 constitute earlier, through injection machine plastics is expelled in the die cavity again, and steel wheel rim 2 is coated, and accomplishes foaming in the injection moulding process simultaneously.The all physics chemistry parameter of the finished product steering handwheel that obtains all is superior to the steering handwheel of conventional urethane foaming.Specifically see table 1
