The invention belongs to the technical field of automobile power steering gears, and particularly relates to an automobile hydraulic power steering gear control valve damping noise reduction structure and a damping noise reduction method thereof. The structure comprises a steering screw, a valve sleeve and a valve element assembly, the valve element assembly is inserted into a center hole of the steering screw, one end of the valve element assembly is connected with the steering screw, the valve sleeve is arranged at the other end of the valve element assembly in a sleeving mode and connected with the valve element assembly in a positioning mode, the outer surface of the valve sleeve is in running fit with the steering screw, a damping ring groove is formed in the valve sleeve, and a damping ring is contained in the damping ring groove. The damping ring groove is communicated with a high-pressure oil groove in the valve sleeve through an oil guide groove. The resonance amplitude of the steering control valve of the automobile hydraulic power steering gear is reduced, the abnormal sound frequency is reduced, and the assembly qualification rate is increased.
本发明属于汽车动力转向器技术领域,特别涉及一种汽车液压动力转向器控制阀阻尼降噪结构及其阻尼降噪方法。包括转向螺杆、阀套及阀芯组件,其中阀芯组件插设于转向螺杆的中心孔内、且一端与转向螺杆连接,阀套套设于阀芯组件的另一端、且与阀芯组件定位连接,阀套的外表面与转向螺杆转动配合,阀套上设有阻尼环槽,阻尼环槽内容置有阻尼环,阻尼环槽通过导油槽与阀套上的高压油槽连通。本发明减少汽车液压动力转向器转向控制阀的共振振幅,降低异响频率,提高装配合格率。
