The invention relates to the technical field of steering wheels, and provides a steering wheel framework and a steering wheel, the steering wheel comprises a rim, an annular groove and a reinforcing rib plate, the rim comprises a first semicircular area and a second semicircular area, the annular groove is formed in one side of the rim in the circumferential direction, the reinforcing rib plate is installed in the annular groove along the annular track of the annular groove, and the reinforcing rib plate is provided with a notch; the notch is formed in the second semicircular area, and the two ends of the notch are symmetrically arranged in the second semicircular area; the annular groove is formed in the rim of the steering wheel in the circumferential direction, the purpose of light weight of the steering wheel framework is achieved, the reinforcing rib plate is arranged in the annular groove, the overall rigidity of the steering wheel framework is greatly improved on the premise that the weight is not obviously increased, and the reinforcing rib plate is arranged in the second semicircular area, so that the overall rigidity of the steering wheel framework is greatly improved. Stress can be distributed more evenly when the steering wheel framework bears loads, local stress concentration is reduced, and therefore the problem that the steering wheel is prone to shaking in the 12 o'clock direction is solved.

    本发明涉及转向盘技术领域,提供一种转向盘骨架及转向盘,转向盘包括轮缘、环槽和加强筋板,轮缘包括第一半圆形区域和第二半圆形区域,环槽沿周向设置在轮缘的一侧,环槽中沿其环形轨迹安装有加强筋板,加强筋板设置有缺口,缺口设置在第二半圆形区域中,且缺口的两端呈对称设置在第二半圆形区域中;本发明通过转向盘沿周向在轮缘上设置环槽,达到转向盘骨架的轻量化目的,通过在环槽中设置加强筋板,在不显著增加重量的前提下,大幅提高转向盘骨架的整体刚度,通过将加强筋板的缺口设置在第二半圆形区域中,使得转向盘骨架在承受载荷时能够更加均匀地分布应力,减少局部应力集中,从而解决转向盘12点方向易抖动的问题。
