Problems solved by technology

Its disadvantages are that the thickness of the thrust plate is thin and the strength is low, and it is easy to deform under high pressure and high temperature, which will intensify the wear between the thrust plate, pressure plate and rotor, and there will be noise, and the worn-out particles will cause jamming. Valve, which leads to the failure of the steering pump of the car; the flatness requirement of the bottom surface of the thrust plate is quite high, and phosphating treatment is required, which results in high processing costs; the oil inlet passage area is large, the oil passage is tortuous, the energy loss is serious, the oil inlet efficiency is low, and it is easy to Cavitation noise at high RPM

Abstract

The invention discloses an oil feed channel of an automobile steering pump. The channel includes a housing, a thrust plate and an oil inlet. The inside of the housing is provided with a supporting surface, which is equipped with a U-shaped first oil feed groove. The thrust plate is arranged over the supporting surface, and is provided with a second oil feed groove, which is arranged correspondingly to the first oil feed groove so as to form an oil feed channel. One end of the oil feed channel is in connection with the oil inlet. The outer diameter of the thrust plate is provided with an O-shaped ring. The oil feed channel is formed by the first oil feed groove and the second oil feed groove of the thrust plate jointly, thus avoiding the problem of difficult cleaning of an original high pressure oil area in the housing and improving cleanliness; the thickness and strength of the thrust plate are increased, thus reducing internal part wearing and improving reliability of the steering pump; meanwhile, plane bond sealing is replaced by O-shaped ring sealing, thus improving the sealing effect and enhancing the efficiency of the steering pump.

Description

technical field [0001] The invention relates to the field of automobile steering pumps, in particular to an oil inlet passage of an automobile steering pump. Background technique [0002] The thrust plate and the casing are two important parts of the steering pump. Together with the cam ring, the pressure plate and the rear cover, they form an oil inlet passage, in which low-pressure oil flows; the high-pressure oil passes through the oil inlet on the thrust plate. The port flows to the bottom of the housing. In order to separate the high and low pressure oil areas, the existing technology uses the thrust plate to closely fit the large plane of the housing to play a sealing role. Its disadvantages are that the thickness of the thrust plate is thin and the strength is low, and it is easy to deform under high pressure and high temperature, which will intensify the wear between the thrust plate, pressure plate and rotor, and there will be noise, and the worn-out particles will ...
