FIELD: transport engineering. ^ SUBSTANCE: invention can be used to decrease course drift of trailers of tractor trains. Proposed automatic device to decrease course drift of trailer has operating members in for of hydraulic cylinders mounted on trailer chassis, electromagnetically controlled hydraulic system, hydraulic pump and distributor with bypass valve. Device is furnished with additional independent operation distributors controlled by solenoids arranged on trailer chassis, transistors forming power circuit including solenoids and lamps showing direction of trailer drift arranged in driver's cab and control circuit including contact group which controls operation of operating members and being essentially sealed contacts controlled by permanent magnet and arranged on chassis of trailer between trailer slewing circle and load platform. Placed in control circuit is sealed contact operated by permanent magnet and located on steering column which controls operation of automatic device reducing drift of trailer at cornering. ^ EFFECT: increased speed of train and capacity, reduced tendency to jack-knifing when negotiating slopes, simplified design. ^ 4 dwg |
