A viable model for inflation driven by a torsion function in a Friedmann background is presented. The scalar spectral index in the interval \(0.92\lesssim n_{s}\lesssim 0.97\) is obtained in order to satisfy the initial conditions for inflation. The post inflationary phase is also studied, and the analytical solutions obtained for scale factor and energy density generalizes that ones for a matter dominated universe, indicating just a small deviation from the standard model evolution. The same kind of torsion function used also describes satisfactorily the recent acceleration of the universe, which could indicate a possible unification of different phases, apart form specific constants

提出了在弗里德曼背景下由扭转函数驱动的可行的通货膨胀模型。为了满足膨胀的初始条件，获得了区间\（0.92 \ lesssim n_ {s} \ lesssim 0.97 \）中的标量频谱指数。还对膨胀后阶段进行了研究，针对比例因子和能量密度获得的分析解决方案对以物质为主的宇宙进行了概括，表明与标准模型的发展仅存在很小的偏差。所使用的相同类型的扭转函数还令人满意地描述了宇宙的最新加速度，这可能表明除了特定常数之外，不同相位可能会统一。
