Embodiment Construction

[0009] As shown in the figure, the present invention is mainly composed of an oil distribution plate body 1 and a central hole 2 . The oil distribution plate body 1 is provided with two oil suction windows 3 and two oil pressure windows 4 symmetrical to the central hole 2 , and two pressure balance chambers 5 symmetrical to the central hole 2 .

[0010] The pressure balance chamber 5 makes the oil in the sealed volume transition from the oil suction chamber to the oil pressure chamber when the oil pump is working, and first passes through the pressure balance chamber 5, so that the pressure of the oil in the chamber rises close to the pressure of the oil pressure chamber, and then with the pressure The oil chambers are connected to reduce the output oil pulsation.

[0011] The oil distribution plate body 1 is provided with an oil suction window angle θ symmetrical to the central hole 2 1 and oil pressure window angle θ 2 and pressure balance chamber angle θ 3 The proportion...

Abstract

The invention discloses an oil-distributing disk with two pressure balance chambers, which mainly comprises an oil-distributing disk body and a centre hole 2. The oil-distributing disk body is provided with two oil absorption windows and two pressure oil windows which are symmetrical with the center hole, and also provided with the two pressure balance chambers which are symmetrical with the center hole. When an oil pump works, the pressure balance chambers cause that firstly the oil in the sealing volume passes the pressure balance chambers when transiting to a pressure oil chamber from an oil absorption chamber to cause the oil pressure in the chambers to rise and be close to the pressure of the pressure oil chamber, and then is communicated with the pressure oil chamber, thus reducing output oil pulsating movement. The oil-distributing disk body is provided with an oil absorption window angle theta , a pressure oil window angle theta and a pressure balancing chamber angle theta which are symmetrical with the centre hole and respectively account for 12-25%, 12-25%, and 0.5-1% of the periphery of the oil-distributing disk. The angel gamma and gamma of the sealing areas between the two oil absorption windows and the two pressure oil windows respectively account for 18-25% and 20-30% of the periphery of the oil-distributing disk. The oil-distributing disk is applied to a motor steering pump.

Description

technical field [0001] The invention relates to an oil distribution plate with a pressure balance chamber for an automobile power steering pump, belonging to the technical field of manufacture of automobile power steering mechanisms. Background technique [0002] With the rapid development of the automobile industry, people have higher requirements for driving comfort and safety, and higher requirements for the performance of automobile hydraulic steering systems. Existing automobile power steering pump is mainly made up of pump body, pump cover, pump shaft, stator, rotor, blade, oil distribution plate etc. Due to the structural design of the parts, there are the following main defects: the output oil pressure of the oil pump fluctuates greatly during steering, so that the steering noise is large, which affects the comfort of driving. Contents of the invention [0003] The purpose of the present invention is to provide an oil distribution plate with a pressure balance cha...
