Abstract
The utility model relates to a hydraulic system used for a driving stabilizer bar of an automobile. A hydraulic pump outlet of the system is communicated with a first branch and a second branch; the first branch is communicated with a first three-position four-way electromagnetic valve, a first speed regulating valve, a second speed regulating valve, a first one-way valve, a second one-way valve and a first hydraulic cylinder to form a front-rod hydraulic loop; and the second branch is communicated with a second three-position four-way electromagnetic valve, a third speed regulating valve, a fourth speed regulating valve, a third one-way valve, a fourth one-way valve and a second hydraulic cylinder to form a rear-rod hydraulic loop. The hydraulic system has two working states (forward stroke and backward stroke) so as to increase a responding speed and an action speed of the driving stabilizer bar. A two-way hydraulic lock is arranged on an oil path of an inlet/outlet of each of the hydraulic cylinders so that the hydraulic cylinder can stay at any place and can be locked; therefore, the driving stabilizer bar can stay at any place and can be locked to ensure the work reliability of a driving stabilizer bar system of the automobile; moreover, the hydraulic loops with the same type are adopted at the front part and the rear part so as to avoid action interference of the two hydraulic cylinders.

Visible by Fig. 1; The left side is a bar hydraulic circuit 8.1 before the active stability lever system; The right side is a bar hydraulic circuit 8.2 behind the active stability lever system, and the two structure is identical, respectively independent action bar behind bar and the active stability lever system before automobile active stability lever system; Both mode of operations are identical, so the following preceding bar hydraulic circuit 8.1 of active stability lever system that is directed against is analyzed.
The bar hydraulic circuit is realized following mode of operation before the active stability lever system:
1, hydraulic actuating cylinder process, promptly hydraulic actuating cylinder is zero to the stroke maximum from stroke.During first three position four-way electromagnetic valve, 3.1 left end electromagnet 1YA energising; The P mouth communicates with the A mouth; The B mouth communicates with the T mouth, and hydraulic oil flows to through the P mouth of first three position four-way electromagnetic valve 3.1 from Hydraulic Pump 1 outlet, is flowed out by the A mouth; Through first governor valve 4.1; Flow into first check valve 5.1 of the left end of first bidirectional hydraulic lock from the M mouth, flow out entering first hydraulic actuating cylinder 6.1 left side rodless cavities by the E mouth, first bidirectional hydraulic lock is through second check valve 5.2 of the right-hand member of control oil channel m reverse-conducting first bidirectional hydraulic lock simultaneously; At this moment hydraulic oil can pass through first check valve, 5.1 inflows, first hydraulic actuating cylinder, the 6.1 left side rodless cavities of the left end of first bidirectional hydraulic lock; Simultaneously the hydraulic oil of the right side rod chamber of first hydraulic actuating cylinder 6.1 is flowed out by the F mouth, second governor valve 4.2 of behind second check valve 5.2 of the right-hand member of first bidirectional hydraulic lock, flowing through, entering hydraulic reservoir 7 after the B mouth of first three position four-way electromagnetic valve 3.1 flows into the outflow of T mouth.At this moment can realize that hydraulic cylinder travel is zero to stroke maximum, i.e. hydraulic actuating cylinder process.
2, hydraulic actuating cylinder moves back journey, and promptly hydraulic actuating cylinder is zero from the stroke maximum to stroke.During first three position four-way electromagnetic valve, 3.1 right-hand member electromagnet 2YA energising; The P mouth communicates with the B mouth; The A mouth communicates with the T mouth, and hydraulic oil flows to through the P mouth of first three position four-way electromagnetic valve 3.1 from Hydraulic Pump 1 outlet, is flowed out by the B mouth; Through second governor valve 4.2; Flow into right-hand member second check valve 5.2 of first bidirectional hydraulic lock from the N mouth, flowed out by the F mouth and get into first hydraulic actuating cylinder, 6.1 right side rod chambers, first bidirectional hydraulic lock is through first check valve 5.1 of the left end of control oil channel n reverse-conducting first bidirectional hydraulic lock simultaneously; At this moment hydraulic oil can pass through second check valve, 5.2 inflows, first hydraulic actuating cylinder, the 6.1 right side rod chambers of the right-hand member of first bidirectional hydraulic lock; The hydraulic oil of first hydraulic actuating cylinder, 6.1 left side rodless cavities is flowed out by the E mouth simultaneously, and first governor valve 4.1 of behind left end first check valve 5.1 of first bidirectional hydraulic lock, flowing through gets into hydraulic reservoir 7 after the A mouth of first three position four-way electromagnetic valve 3.1 flows into the outflow of T mouth.At this moment can realize that the hydraulic cylinder travel maximum is zero place to stroke, promptly hydraulic actuating cylinder moves back journey.
3. hydraulic actuating cylinder stops at an arbitrary position.When first three position four-way electromagnetic valve, 3.1 two ends electromagnet 1YA and 2YA all cut off the power supply; Then this moment, first three position four-way electromagnetic valve 3.1 was in meta, and hydraulic oil can't flow into first three position four-way electromagnetic valve 3.1, and Hydraulic Pump 1 works on; Cause Hydraulic Pump 1 to export to pressure increase in the oil circuit between 3.1 imports of first three position four-way electromagnetic valve; When pressure increased to by pass valve 2 setting pressures, by pass valve 2 will be opened, and unnecessary hydraulic oil will flow directly into hydraulic reservoir 7 through by pass valve 2.And before the active stability lever system in the bar hydraulic circuit 8.1, two first check valves 5.1 are all closed with second check valve 5.2, and hydraulic oil can't or flow out first hydraulic actuating cylinder 6.1, then first hydraulic actuating cylinder, 6.1 bidirectional lockings through the inflow of first bidirectional hydraulic lock.Realize that promptly hydraulic actuating cylinder locks the effect of stop at an arbitrary position.
Can find out from above-mentioned principle of work; Automobile active stability bar hydraulic work system state is less; Can realize that quick switching-over action and optional position stop, can satisfy the requirement of automobile active stability lever system speed of response and responsiveness, the setting of two hydraulic circuits can be avoided the interference of preceding bar of active stability bar and the required action of back bar; And reduce the requirement of production design economy, the principle of this hydraulic efficiency pressure system also can be applicable to other workplace.
Bar hydraulic circuit principle of work is identical with the preceding bar hydraulic circuit principle of work of active stability lever system behind the active stability lever system.
