Magnetic post C14 is inserted into magnetic groove C... 15 is magnetically connected to the iron sheet on the inner wall of the magnetic groove C15, so that the mounting cover 4 is initially fixed to the left ring 2 and the right ring 3 to prevent the mounting cover 4 from falling off. The mounting cover 4 is then fixed to the mounting block C10 by bolts 11, so that the mounting cover 4 is fixed to the rear side of the left ring 2 and the right ring 3. At this time, the housing 1 is located inside the soundproof cover 5, and the noise generated by the steering pump will be reduced by the soundproof cover 5, which plays a role in preventing noise transmission. In summary, this utility model has a noise reduction function, which solves the problem that existing steering pumps usually do not have a noise reduction function, and the steering pump housing can only block the transmission of a small amount of noise, which cannot effectively reduce the noise and cause noise pollution.

[0020] Preferably, a magnetic post A6 is fixedly installed on the left side of the right ring 3, and a magnetic groove A7 is formed on the right side wall of the left ring 2. An iron sheet is fixedly installed on the inner side wall of the magnetic groove A7.
