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 <1>, a pressure oil window angle theta<2> and a pressure balancing chamber angle theta <3> 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 <1> and gamma <2> 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
The present invention relates to the oil distribution casing of a kind of boosting pump for car steering, belong to the manufacturing technology field of motor turning servomechanism with the band pressure balance chamber.
Background technique
Along with the develop rapidly of automotive industry, people also have higher requirement to the performance of automobile hydraulic steering system to the travelling comfort of driving, the raising of security requirement.Existing boosting pump for car steering mainly is made up of the pump housing, pump cover, pump shaft, stator, rotor, blade, oil distribution casing etc.Because there is following major defect in the component structural design reasons: the pulsation of oil pump output oil liquid pressure turns to noise big to making, the travelling comfort that influence is driven greatly when turning to.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, using effect is good, can effectively reduce oil pump output oil liquid pressure pulsation when turning to, thereby effectively reduces the oil distribution casing of the band pressure balance chamber of steering system noise when turning to.
In order to achieve the above object, the present invention has mainly adopted following technological scheme to realize.The present invention comprises oil distribution casing body 1 and center hole 2 for the oil distribution casing of boosting pump for car steering with the band pressure balance chamber.Establish on the described oil distribution casing body about centrosymmetric two oil sucking windows 3 and two oily windows 4 of pressure, also be provided with about centrosymmetric two pressure balance chambers 5, make fluid in oil pump when work sealed volume from oil sucting cavity when the pumping cavity transition, earlier through pressure balance chamber, chamber inner fluid pressure is risen near pumping cavity pressure, communicate with pumping cavity again, thereby reduce to export the fluid pulsation.Establish on the described oil distribution casing about centrosymmetric oil sucting cavity angle θ
1With pumping cavity angle θ
2With pressure balance chamber angle θ
3The ratio that accounts for the oil distribution casing circumference can be respectively 12～25%, 12～25%, 0.5～1% oil sucking window and press the angle γ of sealing area between the oily window
1And γ
2The ratio that accounts for the oil distribution casing circumference can be respectively 18～25% and 20～30%.
The present invention compared with prior art, have following outstanding advantage and good effect: (1) set up the fluid that makes in oil pump when work sealed volume from oil sucting cavity when the pumping cavity transition, earlier through pressure balance chamber, chamber inner fluid pressure is risen near pumping cavity pressure, communicate with pumping cavity again, thereby reduce to export the fluid pulsation, reduced the noise of pump.(2) oil distribution casing is provided with the rational oil sucting cavity angle of ratio θ
1, pumping cavity angle θ
2, pressure balance chamber angle θ
3The angle γ of sealing area
1And γ
2Make the oil suction of pump more abundant, effectively prevented not foot phenomenon of the empty and oil suction of the suction of pump, reduced the noise of pump.
The present invention is applicable to boosting pump for car steering.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Description of drawings
Accompanying drawing is an overall structure view of the present invention.
Embodiment
As shown in the figure, the present invention mainly is made up of oil distribution casing body 1 and center hole 2.Described oil distribution casing body 1 is provided with two oil sucking windows 3 and two the oily windows 4 of pressure with center hole 2 symmetries, also is provided with two pressure balance chambers 5 with center hole 2 symmetries.
Described pressure balance chamber 5 make fluid in oil pump when work sealed volume from oil sucting cavity when the pumping cavity transition, earlier through pressure balance chamber 5, chamber inner fluid pressure is risen near pumping cavity pressure, communicate with pumping cavity again, thereby reduce to export the fluid pulsation.
Establish oil sucking window angle θ on the described oil distribution casing body 1 with center hole 2 symmetries
1With the oily window angle θ of pressure
2With pressure balance chamber angle θ
3The ratio that accounts for the oil distribution casing circumference can be respectively 12～25%, 12～25%, 0.5～1%, oil sucking window and press the angle γ of sealing area between the oily window
1And γ
2The ratio that accounts for the oil distribution casing circumference can be respectively 18～25% and 20～30%.
The present invention is applicable to boosting pump for car steering.
