Description
Известно применение пружинных и npeAOxpaHHTevibHbix устройств в конструкци х автосцепов, действующих при перегрузках сельскохоз йственных , машин.It is known the use of spring and npeAOxpaHHTevibHbix devices in the designs of automatic couplings operating during agricultural machinery overloads.
Основными недостатками таких устройств вл ютс слаба чувствительность и трудность регулировки на требуемое усилие разъединени при перегрузках.The main disadvantages of such devices are their poor sensitivity and the difficulty of adjusting for the required separation force in case of overloads.
Предлагаемый автосцеп отличаетс от известных тем, что он выполнен в виде соединенного с золотником гидрораспределител гидроцилиндра двойного действи . На штоке поршн гидроцилиндра расположены две щеки, между которыми шарнирно монтирована защелка. Щеки под действием щтока перемещаютс в осевом направлении в неподвижном корпусе, жестко соединенном с гидроцилиндром. Защелка св зана с неподвижным корпусом посредством троса. Ролик, установленный в передней части прицепа, действует при перегрузках на защелку, вызыва при этом срабатывание редукционного клапана, расположенного в гидроцилиндре.The proposed coupler differs from the known ones in that it is made in the form of a double acting hydraulic cylinder connected to the spool valve. On the piston rod of the hydraulic cylinder there are two cheeks, between which a latch is pivotally mounted. The cheeks are moved axially by the action of the stem in a stationary body rigidly connected to the hydraulic cylinder. The latch is connected to the fixed housing by means of a cable. The roller mounted in the front of the trailer acts upon overloads on the latch, thus triggering the reduction valve located in the hydraulic cylinder.
На чертеже изображена схема автосцепа, который устанавливаетс на тракторе, имеющем раздельно-агрегатную гидросистему.The drawing shows an auto coupler diagram which is mounted on a tractor having a separate aggregate hydraulic system.
Конструкци автосцепа включает защелку /, щеки 2, корпус 3 автосцепа , гидроцилиндр 4, редукционный клапан 5, трос 6. Когда сопротивление прицепной или навесной сельскохоз йственной машины превышает .расчетное, ролик 7, установленный в передней части этих машин, через защелку и щеки перемещает щток и поршень . При закрытом золотнике в левой полости цилиндра возникает давление, превышающее заданное сопротивление редукционного клапана.Coupling includes the latch /, cheeks 2, body 3 of the automatic coupler, hydraulic cylinder 4, reducing valve 5, cable 6. When the resistance of the trailed or mounted agricultural machine exceeds the calculated, roller 7, installed in front of these machines, moves brush and piston. When the valve is closed in the left cavity of the cylinder, a pressure that exceeds the specified resistance of the pressure reducing valve occurs.
