The invention discloses a power steering device and an automobile steering system. The power steering device comprises a steering gear box, an oil can and a connecting oil pipe. The steering gear boxcomprises a case and a rotating shaft extending out of the case; a through hole is formed in the oil can, the rotating shaft penetrates through the through hole, and the oil can is mounted on the case; one end of the connecting oil pipe is communicated with an oil outlet of the steering gear box, and the other end of the connecting oil pipe is communicated with an oil inlet of the oil can. According to the power steering device disclosed by the invention, the oil can is directly sleeved on the rotating shaft of the steering gear box; then the oil can is mounted on a case of the steering gear box; the oil outlet of the steering gear box is connected with the oil inlet of the oil can through the connecting oil pipe, so that the steering gear box and the oil can form an integrated part, partssuch as an oil can support do not need to be arranged, the length of the connecting oil pipe is greatly reduced, the cost of the whole vehicle is reduced, and the assembling space occupied by the oilcan is reduced, and the assembling time occupied by the oil can is shortened.

    本发明公开了一种动力转向装置及汽车转向系统,动力转向装置包括方向机,油壶和连接油管,方向机包括机箱以及从机箱伸出的转轴;油壶上开设有通孔,转轴穿过通孔,且油壶安装在机箱上;连接油管的一端与方向机的出油口连通,连接油管的另一端与油壶的进油口连通。本发明的动力转向装置直接将油壶套设在方向机的转轴上,再将油壶安装在方向机的机箱上,通过连接油管将方向机的出油口和油壶的进油口连接起来,使得方向机和油壶成为一个整体式零部件,无需设置油壶支架等部件,且极大地减小了连接油管的长度,在降低了整车成本的同时,减小了油壶占用的装配空间和装配时间。
