VEHICLE CONTROLLED SUSPENSION Russian patent published in 1994 - IPC

FIELD: vehicles. SUBSTANCE: suspension has flexible member 1, shock absorber 2 and power cylinder 3 mounted in parallel and connecting wheel 4 with spring-mounted part 5. Suspension also has control solenoid-operated valve 6, vibration generator 7, interlock device 8, pressure pickup unit 9, pressure pump 10, tank 11, safety valve 12 and connection pipelines. Vibration generator 7, acting on control solenoid-operated valve 6 at frequency equal to its own frequency but in phase opposition to vehicle body vibrations, connects delivery pipeline of hydraulic pump with respective space of power cylinder at time, when opposed space is connected with return pipeline and vice versa. Connection in phase opposition is ensured by pickup unit and interlock device 8. At preset frequency power cylinder acts on flexible member 1, decreasing resultant action on vehicle body. EFFECT: enhanced reliability of operation. 1 dwg, 1 tbl
