In the embodiment of the present disclosure, the flow direction of the first check valve 30 is from the adapter oil inlet 201 to the adapter oil outlet 202, and in the process of using the hydraulic steering gear adapter, the high-pressure oil can only flow from the adapter oil inlet 201 to the adapter oil outlet 202, and cannot flow from the adapter oil outlet 202 to the adapter oil inlet 201. A first check valve 30 is arranged in the adapter oil inlet 201, so that high-pressure oil can only flow from the adapter oil inlet 201 to the adapter oil outlet 202, and backflushing noise or shaking caused by backflow of the high-pressure oil is avoided.

When the high-pressure oil impacts the diaphragm 307 to move, the supporting rod 308 moves along with the diaphragm 307, if the pressure of the high-pressure oil on the diaphragm 307 is different, the diaphragm 307 inclines, the supporting rod 308 inclines, and the inclination of the supporting rod 308 is limited due to the fact that the other end of the supporting rod 308 is attached to the inner side wall of the cylinder cavity 303, so that the inclination of the diaphragm 307 can be limited, and the stability of the diaphragm 307 is guaranteed.
Meanwhile, the plurality of support rods 308 are arranged at intervals in the circumferential direction of the diaphragm 307 so that a gap is provided between adjacent two support rods 308, so that high-pressure oil can flow into the cylinder chamber 303 through the gaps.

The embodiment of the disclosure also provides an automobile which comprises the hydraulic steering gear shown in any one of the figures.
In the embodiment of the present disclosure, high-pressure oil in the steering oil pump flows from the high-pressure oil pipe to the adapter oil inlet 201, the high-pressure oil flows to the adapter oil outlet 202 through the throttling round hole 203, and the high-pressure oil flows to the hydraulic steering gear oil inlet again, and then flows to the inside of the hydraulic steering gear through the hydraulic steering gear oil inlet, so as to provide power for the hydraulic steering gear. Because the diameter of the throttling round hole 203 is smaller than that of the adapter oil inlet 201, when high-pressure oil flows from the adapter oil inlet 201 to the throttling round hole 203, the flow of the high-pressure oil in the throttling round hole 203 is reduced, even if the high-pressure oil discharged by the steering oil pump pulsates, the flow of the high-pressure oil flowing into the throttling round hole 203 is still continuous, so that the high-pressure oil flowing into the hydraulic steering gear is also continuous, the high-pressure oil entering the hydraulic steering gear does not have the phenomenon of pulsation, the shaking of the hydraulic steering gear is improved, and the shaking of an automobile is effectively relieved. The ratio of the length of the throttling round hole 203 to the diameter of the throttling round hole 203 is between 2 and 6, so that the throttling round hole 203 is a long-strip-shaped hole, the flowing time of high-pressure oil in the throttling round hole 203 is long, the situation that the high-pressure oil rapidly flows into the hydraulic steering gear from the adapter oil inlet 201 and impacts the hydraulic steering gear to generate shaking is avoided, and shaking of an automobile can be further relieved.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
