Description of symbols in figure: oil pump 1, lip-type packing 2, inhalation type filter 3, bypass valve 4, housing 5, filter core 6, high pressure filter 7, cooling and lubricating control valve 8, main pressure control valve 9, principal pressure guiding valve 10, oil sump 11, cooler 12.
Embodiment
In ensuing description, for the filtration system of dual-clutch transmission, but filtration system of the present utility model also can be used in single clutch automatic transmission case and multi-clutch automatic transmission case.
With reference to figure 1, the oil pump 1 of the present embodiment is directly connected with inhalation type filter 3, and adopts lip-type packing 2 to seal between the two.When oil pump 1 works, its pumping action can make inhalation type filter 3 enter its filter core from outside oil suction to filter, and for high pressure filter 7 described later, inhalation type filter 3 is a low-pressure filter.Inhalation type filter 3 adopts pocket type or the paper-folded filter core of market sale, the filter area of the filter core of script individual layer is improved, the dust containing capacity of inhalation type filter 3 is increased, improves the working life of product, saves cost.Lip-type packing 2 improves the effective sealing between oil pump 1 and inhalation type filter 3, reduces and inhales empty risk.
With reference to figure 2, the high pressure filter 7 in the present embodiment comprises housing 5, is positioned at filter core 6 and the bypass valve 4 of housing 5 inside.On oil circuit direction, high pressure filter 7 is positioned at the rear of oil pump 1, and fluid enters high pressure filter 7 under the pressure effect of oil pump 1, flows out, after filter core 6 filters as shown in the tubular wire of the band arrow in Fig. 2.When hydraulic pressure increases or high pressure filter 7 blocking causes pressure to raise, bypass valve 4 will be opened, and some or all of fluid filters without filter core 6 and directly flows out high pressure filter 7.Filter core 6 adopts paper-folded filter core, the filter area of the filter core of script roll type is improved, the dust containing capacity of high pressure filter 7 is increased, improves the working life of product, saves cost.
With reference to figure 3, the filtration system for automatic transmission case comprises oil sump 11, inhalation type filter 3, oil pump 1, high pressure filter 7, main pressure control valve 9, principal pressure guiding valve 10, cooling and lubricating control valve 8 and cooler 12.The mating reaction of above-mentioned each parts is closed and is: under the suction of oil pump 1, fluid enters inhalation type filter 3 from oil sump 11, carries out single filter.Fluid pressurizes through oil pump 1 after inhalation type filter 3 flows out, pressure adjustment is carried out by main pressure control valve 9, main pressure control valve 9 regulates the valve element position controlling principal pressure guiding valve 10 by pressure, thus making fluid be divided into two branch roads: a road enters cleans to fluid actuators such as requiring relatively not high solenoid valve, and an other road enters high pressure filter 7 and carries out cascade filtration after cooler 12 cools.Fluid cooled lubrication control valve 8 after high pressure filter 7 filters is dispensed to and cleans the relatively high double clutch lubrication mechanism of requirement or Chi Zhou lubrication mechanism to fluid, or is dispensed to Liang Ge lubrication mechanism simultaneously.When hydraulic pressure increases or high pressure filter 7 blocking causes pressure to raise; bypass valve 4 will be opened; now part fluid without high pressure filter 7 filter core 6 but directly enter double clutch lubrication mechanism and/or Chi Zhou lubrication mechanism; this suppresses the danger of dead system by greatly reducing overpressure; serve good high-pressure security protection, improve the Security of product so that whole system.。
