The invention discloses a flexible steering wheel. The flexible steering wheel comprises a steering wheel framework, the steering wheel framework is formed by composite injection molding of PP plasticand glass fibers, a metal support plate is pre-buried in the middle in the steering wheel framework, and the lower end of a center hole of the metal support plate is connected with a spline housing;arc-shaped outer rim parts are symmetrically arranged at the positions, corresponding to the three clock and the nine clock of the steering wheel, of the steering wheel framework. An annular inner foaming body is arranged outside the rim of the steering wheel framework, is formed by EVA foam in an injection molding mode and wraps the outer rim of the steering wheel framework. An outer foaming bodyis arranged outside the inner foaming body and wraps the inner foaming body and spokes of the steering wheel framework. According to the steering wheel, the weight of the steering wheel can be reduced, and the tensile strength and the bending strength of the steering wheel are guaranteed; and the flexibility of the steering wheel can be improved, so that the harm of the steering wheel to driversand passengers during vehicle collision is effectively reduced.
本发明公开了一种柔性转向盘,包括转向盘骨架,所述转向盘骨架是由PP塑料和玻璃纤维复合注塑成型,在转向盘骨架内中部预埋有金属支架板,在金属支架板的中心孔下端连接有花键套;所述转向盘骨架对应转向盘的3、9点位置对称设有弧形外轮缘部;在转向盘骨架的轮缘外面设有环形内发泡本体,内发泡本体是由EVA泡沫注塑而成,并将转向盘骨架的外轮缘部包裹在内;在内发泡本体的外面设有外发泡本体,外发泡本体将内发泡本体和转向盘骨架的辐条包裹在内。该转向盘不仅能够减轻该转向盘的重量,保证该转向盘的拉伸强度和弯曲强度;而且能够提高该转向盘的柔软性,从而有效降低车辆碰撞时转向盘对司乘人员的伤害。
