动力转向油泵
本技术属于机械
,涉及一种动力转向油泵。
技术介绍
助力泵用于汽车转向系统,是汽车转向的动力源。用于汽车转向系统的助力泵又称为动力转向油泵,包括皮带轮、转轴、配油盘、定子、转子、叶片和流量控制阀等,皮带轮与汽车的发动机转轴或者其他动力转轴连接。在转子上设置叶片的转向油泵称为叶片式转向油泵。中国专利文献资料公开提出了一种汽车动力转向油泵[申请号:200620093811.1;公告号:200964945Y],主要由泵体、进油口、油道、压力板、高压区、定子、转子、叶片、后盖、阀孔、滑阀、主轴组成,在泵体和后盖上对应设置分流槽和吸油槽,在主轴上装有套形金属滑动轴承。压力板又称为配油盘,一般在定子的两端均设置一个配油盘,靠近高压区的配油盘受到升高的液压作用,容易产生变形,从而会降低油泵的使用寿命。
