Изобретение относитс к области автомобилестроени , в частности к системам смазки агрегатов трансмиссии автомобилей, у которых при нейтральном ноложении раздаточной коробки, включаемом во врем отбора мощности на сто нке, не обеснечиваетс смазка деталей раздаточной коробки и установленной на ней коробки отбора мощности путем разбрызгивани масла из масл ной ванны.The invention relates to the automotive industry, in particular, to the lubrication systems of automobile transmission units, which, when the transfer case is switched on in neutral, switched on during power take-off, do not lubricate the parts of the transfer case and the power take-off box installed on it by splashing oil from oil Noah baths.
Известна система принудительной смазкн агрегатов трансмиссии транспортного средства , содержаща гидронасос, приводимый во вращение от вала отбора мощности, трубопровод , соедин ющий всасывающую полость гидронасоса с масл ной ванной гидроагрегата , например раздаточной коробки , а нагнетательна полость соединена с нотребителем смазкн.A known system of forced lubrication of vehicle transmission units, comprising a hydraulic pump driven by rotation from the power take-off shaft, a pipeline connecting the suction cavity of the hydraulic pump to the oil bath of the hydraulic unit, for example, a transfer case, and the pressure cavity is connected to the consumer.
Недостатком систем известной конструкции вл етс нестабильное засасывание масла гидронасосом при пуске, усиливающеес по мере износа деталей насоса, а также при охлаждении масла. При этом коробка отбора мощности может быть поставлена под нагрузку не одновременно с включением , а только носле того, как произойдет самовсасывание масла насосом из масл ной ванны.A disadvantage of systems of known design is the unstable suction of oil by a hydraulic pump at start-up, which increases as the parts of the pump wear and also when the oil is cooled. In this case, the power take-off box can be placed under load not at the same time as it is turned on, but only when the oil from the oil bath is self-priming the pump.
Пелью изобретени вл етс новышенне надежностн пуска гидронасоса.The invention is the new reliability of the hydraulic pump start.
Цель достигаетс тем, что снстема C ia6жена отсекающим клананом, а всасывающа полость гидронасоса снабжена каналом со всасывающим коллектором двигател транспортного средства, при этом отсекающий клапан установлен в упом нутом канале .The objective is achieved in that the system C ia6 is cut-off clan, and the suction cavity of the hydraulic pump is provided with a channel with the suction manifold of the vehicle engine, and the shut-off valve is installed in the said channel.
Кроме того, система снабжена занорным устройством, установленным в канале, сообщающем всасывающий коллектор двигател транснортного средства со всасывающей нолостью гидронасоса.In addition, the system is equipped with an emptying device installed in the channel, which connects the suction manifold of the transnormal engine means with the suction side of the hydraulic pump.
На фиг. 1 схематично изображена система смазки; на фиг. 2 - вид но стрелке А на фиг. 1.FIG. 1 schematically shows a lubrication system; in fig. 2 shows but arrow A in FIG. one.
Гидронасос 1 своей всасывающей полостью 2 через трубопровод 3 соединен с масл ной ванной 4 гидроагрегата, например раздаточной коробки 5, на которой установлена коробка 6 отбора мощности, а через отсекающий клапан 7, расположенный выше оси гидронасоса 1, каналы 8, 9 и запорное устройство 10 - со всасывающим коллектором двигател автомобил (на чертеже не показан). К нагнетательной полости И гидронасоса присоединены манометр 12 и трзбопровод 13. Между всасывающейThe hydraulic pump 1 with its suction cavity 2 is connected via pipe 3 to the oil bath 4 of the hydraulic unit, for example, transfer box 5, on which power take-off box 6 is installed, and through a shut-off valve 7 located above the axis of the hydraulic pump 1, channels 8, 9 and locking device 10 - with the intake manifold of the car engine (not shown). A pressure gauge 12 and a thrb line 13 are connected to the discharge cavity and the hydraulic pump. Between the suction
