The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying drawing 1,2, the utility model comprises the stabilizer rod that the stabilizer rod body of rod 2 and adjustable rigidity stabilizer rod pull bar 11 are formed, control system 8, steering wheel angle sensor 5, wheel speed sensors 14, also comprise based on controlled lockmaking and end stabilizer rod hydraulic pressure support system 6 with conducting, this stabilizer rod hydraulic pressure support system 6 is connected in the left and right sides of the stabilizer rod body of rod 2; One end of this stabilizer rod body of rod 2 is connected with one based on the adjustable rigidity stabilizer rod pull bar 11 of stabilizer rod hydraulic pressure support system 6, and this adjustable rigidity stabilizer rod pull bar 11 links to each other with suspension swing arm 12, and this suspension swing arm 12 is positioned on the wheel 15 of vehicle body fixed mount 3.Described wheel speed sensors 14 links to each other with suspension travel sensor 1, suspension travel sensor 1 is positioned on the bumper 13, wheel speed sensors 14 is positioned on the wheel 15 of vehicle body fixed mount 3, and bumper 13, wheel 15 and steering wheel angle sensor 5 are fixed on the vehicle body fixed mount 3.Described stabilizer rod hydraulic pressure support system 6 is provided with two valves 4, and these two valves 4 are connected with oil storage cylinder 10 separately.Described steering wheel angle sensor 5 is connected on the control system 8 by signal wire (SW) 9 with suspension travel sensor 1, and control system 8 links to each other with valve 4 by control line 7.
Embodiment:
When by the test of the suspension travel sensor 1 on the left and right sides wheel 15 to left and right sides suspension travel difference less than certain threshold amount or when the steering wheel angle amplitude that is recorded by steering wheel angle sensor 5 during greater than threshold amount necessarily, the valve 4 of control system 8 control left and right sides is in closed condition, the stabilizer rod hydraulic pressure support system 6 of the stabilizer rod body of rod 2 left and right sides will be in lockup state like this, this moment, stabilizer rod was equivalent to be connected with vehicle body by the fixed pedestal mode, will equally play opposing body roll effect in steering procedure with traditional stabilizer rod.
When by suspension travel sensor 1 test of left and right sides wheel 15 to left and right sides suspension travel difference greater than certain threshold amount and when the steering wheel angle amplitude that is recorded by steering wheel angle sensor 5 during less than threshold amount necessarily, the valve 4 of control system 8 control left and right sides is in opening, the stabilizer rod hydraulic pressure support system 6 of the stabilizer rod body of rod 2 left and right sides will be in quick condition like this, this moment, stabilizer rod was equivalent to be connected with vehicle body by the supporting way that floats, can't form opposing inclination effect, so just can vehicle run into single wheel and run into higher projection, when big dell or bilateral wheel pavement-height differ greatly operating mode, avoid producing big vehicle body and rock and avoid limiting one-sided suspension travel.
When wheel speed sensors 14 and steering wheel angle sensor 5 calculates the vehicle lateral accelerations less than certain threshold amount, regulate stabilizer rod rigidity by adjustable rigidity stabilizer rod pull bar 11 and give the steering response speed that the whole accounting of the bigger roll rate of front axle is accelerated vehicle.When wheel speed sensors 14 and steering wheel angle sensor 5 calculates the vehicle lateral accelerations greater than certain threshold amount, regulate stabilizer rod rigidity by adjustable rigidity stabilizer rod pull bar 11 and give the convergence rate that the whole accounting of the less roll rate of front axle is accelerated the Vehicular turn motion, increase stability.
