The invention relates to a self-adaptive rigidity real-time adjusting power steering gear, and belongs to the technical field of automobile steering system parts. The self-adaptive rigidity real-time adjusting power steering gear comprises a steering gear body which comprises a shell assembly; the rigidity adjusting module comprises an installation part which is arranged on the shell assembly and used for being connected with the auxiliary frame, and a magnetorheological elastomer component and an electromagnetic induction coil are arranged between the installation part and the shell assembly. Therefore, in the vehicle driving process, the magnitude of the current input by the electromagnetic induction coil is changed, so that the magnetic field generated after the electromagnetic induction coil is electrified is changed, the rigidity and strength of the magnetorheological elastomer component are also changed under the action of the magnetic field, and the vibration energy transmitted to the steering gear body by the auxiliary frame is also changed; the rigidity of the steering system can be changed according to different road conditions, so that the driving experience of a driver is improved, the diversified requirements of the driver for the rigidity of the steering system are met, and the NVH performance of the whole vehicle is improved.

    本申请涉及一种自适应刚度实时调节动力转向器,属于汽车转向系统零部件技术领域,包括转向器本体,其包括壳体总成;刚度调整模块,所述刚度调整模块包括设置在所述壳体总成上并用于连接所述副车架的安装件,所述安装件和所述壳体总成之间设置有磁流变弹性体构件以及电磁感应线圈。因此,在车辆驾驶过程中,通过改变电磁感应线圈输入的电流大小,使得电磁感应线圈得电后产生的磁场发生变化,在磁场作用下磁流变弹性体构件的刚度强度也随之改变,副车架传递至转向器本体上的振动能量随之改变,即可以针对不同路况,改变转向系统的刚度,以提高驾驶员的驾驶体验差,满足了驾驶员对转向系统刚度的多元化需求,提升了整车NVH性能。
