Наружный стакан закрытой стороной закреплен на оси кронштейна, а внутренний штоковый стакан, имеющий в осевой полости регулируемую по длине опорной балки подвижную стяжку, связан с кронштейном парой рычагов, опирающихся на профильные угловые кулачки кронштейна упорными роликами. Перемычками между стенками стаканов образованы четыре камеры, создающие гидрогазовый блок синхронизации свода и разжима осей колеса. Две камеры со стороны торцов стаканов заполнены газом и соединены калибровочным каналом между собой. Внутренние камеры, связанные каналом, заполнены гидравлической средой с давлением ниже, чем в газовых камерах. Между внутренними камерами расположен поршень, рабочая площадь которого больше со стороны кронштейна, чем со стороны колеса, при этом в двух камерах со стороны колес размещены пружины, а наружный стакан кинематически связан с пружиной-стабилизатором. Технический результат – упреждение в системе подвески проявления пары сил, влияющей на свод и разжим оси колеса транспортного средства при продольном направлении движения в момент наезда минимум одного колеса на пороговое дорожное препятствие или выемку. 2 ил.
