[0002] In the vehicle electro-hydraulic power steering system device, a motor-driven hydraulic pump is usually used. The hydraulic pump is generally installed in the cavity after the installation of the single-layer oil pot and the shell of the electro-hydraulic power steering system device. The cavity is filled with oil. , when the hydraulic pump is working, especially at the rated load, the electro-hydraulic power steering system device composed of the hydraulic pump and its motor drive device will produce disturbing noise, which is caused by the flow pulsation of the hydraulic pump and the torque fluctuation of the drive device. Yes, the noise is transmitted to the air through the oil, single-layer oil pot, and the housing of the electro-hydraulic power steering system, affecting the comfort of the vehicle

Embodiment Construction
[0009] Examples, see attached figure 1 , the inner casing 1 of the hydraulic oiler for the electro-hydraulic power steering system is fixedly mounted on the upper end of the casing 7 of the electro-hydraulic power steering system, the upper end of the inner casing 1 of the oiler is provided with an oil inlet pipe 5 for the oiler, and the inner casing 1 of the oiler is connected with the The housing 7 of the electro-hydraulic power steering system forms a cavity 4 between the inner shell of the oil pot and the housing of the electro-hydraulic power steering system. The hydraulic pump 6 of the electro-hydraulic power steering system is placed between the inner shell of the oil pot and the housing of the electro-hydraulic power steering system. The body cavity 4 is installed in the housing 7 of the electro-hydraulic power steering system. The oil inlet pipe 5 at the upper end of the inner shell 1 of the oil pot is fixedly connected with the upper end of the outer shell 3 of the o...

The invention belongs to hydraulic components, in particular to a hydraulic reservoir for elector-hydraulic power steering systems. The hydraulic reservoir comprises an electro-hydraulic power steering system housing (7) and an electro-hydraulic power steering system hydraulic pump (6). A reservoir inner housing (1) is fixed at the upper end of the electro-hydraulic power steering system housing (7). A reservoir oil inlet tube (5) at the upper end of the reservoir inner housing (1) is fixedly connected with the upper end of a reservoir outer housing (4). The lower end shed of the reservoir inner housing (1) is fixedly connected with the lower end of the reservoir outer housing (4). The inside-outside airtight chamber (2) forms among the reservoir inner housing (1), the reservoir oil inlet tube (5) and the reservoir outer housing (4). The reservoir inner housing and the reservoir outer housing are fixedly connected to form the airtight chamber, the acoustic insulation mode has the effect of stopping propagation of interference noise to air, caused by flow pulsation of a hydraulic pump and torque rippling of a drive device, noise is reduced, and comfort of an automobile is improved.
