BODY OF VEHICLE DESIGNED FOR CARRYING NON-VIBRATION-PROOF LOADS Russian patent published in 1995 - IPC

FIELD: transport. SUBSTANCE: body has frame 1 and container 2 connected by shock absorbers. Each shock absorber is made in form of electrodynamic flexible support consisting of cylindrical spring, adjustable resistor placed inside spring and connected to current source, and amplifier - converter install in series between current source and spring. With shock absorber being compressed, resistance of resistor increases, and current intensity at amplifier-converter input decreases. Amplifier-converter provides such decrease in current in spring coils at which change in electromagnetic rigidity of spring causes decrease in its total rigidity to preset value. Thanks to it reaction of shock absorber remains constant. In case of extension of shock absorber 3, resistance of resistor decreases, current intensity at input of amplifier-converter increases and the latter provides such an increase in current intensity in spring coils at which change of electromagnetic rigidity of spring causes increase in total rigidity to preset value. Reaction of shock absorber 3 remains constant. EFFECT: enhanced reliability of operation. 4 dwg
