Description
обеспечивает сокращение габаритов рулевого механизма и позвол ет получить достаточно большое поперечпое сечение рабочего порш.н в зоне расположени указанных его элементов. provides a reduction in the dimensions of the steering mechanism and allows to obtain a sufficiently large cross-section of the working piston in the area of the specified elements.
На фиг. 1 показан рулевой механизм (поперечный разрез по оси вала рулевой сош-ки ); на фиг. 2 - рулевой механизм, продольный разрез.FIG. 1 shows the steering mechanism (a transverse section along the axis of the shaft of the downstream steering wheel); in fig. 2 - steering, longitudinal section.
Рулевой механизм содержит корпус 1, который разделен ступенчатым рабочим поршнем 2 .на две рабочие полости 3 -и 4. Больша по диаметру ступень 5 поршн снабжена уплотнением 6. Друга ступень 7 поршн снабжена зубчатой рейкой 8, зубь которой наход тс iB зацеплении с сектором 9, жестко св занным или выполненным за одно целое с валом 10 рулевой сошки. На .выступающем из корпуса участке вала 10 выполнены шлицы 11 дл креплени рулевой сошки (на чертеже не показана).The steering mechanism includes a housing 1, which is divided by a stepped working piston 2. On two working cavities 3 and 4. Large in diameter, the piston stage 5 is provided with a seal 6. The other piston stage 7 is equipped with a rack 8, the tooth of which is iB engaged with sector 9 rigidly connected or made in one piece with the shaft 10 of the bipod. On the section of the shaft 10 that protrudes from the body, there are slots 11 for fastening the bipod (not shown).
В стунени 7 порш.и «выполнен сквозной паз 12. Ось 13 паза расположена параллельно плоскости 14, проход щей через впадины зубьев рейки 8. Паз 12 имеет пр моугольное сечение за исключением участка пересечени с центральным отверстием 15, выполненным в рабочем поршне 2.In the piston stun 7, a through groove 12 is made. The groove axis 13 is parallel to the plane 14 passing through the depressions of the teeth of the lath 8. The groove 12 has a rectangular section with the exception of the intersection with the central bore 15 made in the working piston 2.
В пазу 12 с помощью подшипников 16 и 17 установлена копцентрично оси 18 поршн гайка 19. Подшипники 16 и 17 обеспечивают возможность ограниченного поворота гайки 19 и фиксируют ее в радиальном и осевом направлени х относительно поршн . Гайка 19 посредством циркулирующих в замкнутой направл ющей пшриков 20 взаимодействует с вин то .м 21.In the groove 12, the bearings 16 and 16 are set axially with the piston axis 18 of the nut 19. The bearings 16 and 17 allow limited rotation of the nut 19 and fix it in the radial and axial directions relative to the piston. The nut 19, by means of the rims 20 circulating in the closed guide, interacts with the screws 21.
Винт 21 установлен в корпусе 1 с помощью радиального подшипника 22, обеспечивающего Вращение .винта 21 относительно корпуса 1. Перемещение винта в осевом паправлении фиксируетс упорными подшипниками 23 и 24. Конец 25 .винта 21, выступающий из корпуса , служит дл соединени с рулевым валом (На чертеже не показан).The screw 21 is installed in the housing 1 by means of a radial bearing 22, which provides Rotation of the screw 21 relative to the housing 1. The movement of the screw in axial direction is fixed by the thrust bearings 23 and 24. The end 25 of the screw 21 protruding from the housing serves for connection with the steering shaft ( The drawing is not shown).
Гайка 19 имеет радиальный выступ 26, расположсииый в пазу 12. Конец выступа 26 взаимодействует с золотником 27 распределител 28, обеспечивающего соединение рабочих полостей 3 или 4 с источником давлени или со сливом.The nut 19 has a radial protrusion 26 located in the groove 12. The end of the protrusion 26 interacts with the spool 27 of the distributor 28, which connects the working cavities 3 or 4 with a pressure source or with a drain.
Золотник 27, ось 29 которого лежит в ноперечной плоскости, перпенди1кул .рной оси рабочего поршн 2, установлен в корпусе со стороны, противоположной размеп1епию рулевой сошки перпендикул рно оси вала 10.The spool 27, the axis 29 of which lies in the transverse plane perpendicular to the working axis of the working piston 2, is installed in the housing on the side opposite to the steering bipod perpendicular to the axis of the shaft 10.
Рулевой механизм работает следующим образом .The steering mechanism works as follows.
При повороте рулевого вала па некоторый угол св занный с ним винт 21 поворачиваетс относительно корпуса 1 с небольшим зазором , имеющимс между канавками винта 21 и гайки 19 и шариков 20. После того, как указаниый зазор выбран и шарики 20 вступ т во взаимодействие с канавками винта 21When the steering shaft is rotated PA, some angle of the associated screw 21 rotates relative to the housing 1 with a small gap between the grooves of the screw 21 and the nut 19 and the balls 20. After the specified clearance is selected and the balls 20 come into contact with the screw grooves 21
и гайки 19, последн начнет поворачиватьс в подшипниках 16 и 17 за одно целое с винтом 21, т. к осевому неремещению гайки 19 совместно с поршнем 2 преп тствует сила сопротивлени повороту управл емых колес транспортного средства, передающа с на nopujenb через вал рулевой сошки, взаимодействующей с поршнем 2 посредством зубчатого сектора 9.and nuts 19, the latter will begin to turn in bearings 16 and 17 in one piece with screw 21, since axial non-displacement of nut 19 together with piston 2 is impeded by the resistance to rotation of the controlled wheels of the vehicle, transmitting to the nopujenb via the shaft of the bipod, interacting with the piston 2 by means of the toothed sector 9.
Благодар повороту гайки 19 и св занного с ней выстуиа 26 золотник 27 распределител 28 переместитс из нейтрального положени , обеспечива соединение одной из рабочих полостей 3 или 4 с источником давлени , а другой -со сливом. Поршень 2 начнет перемещатьс в осевом направлении под действием жидкости под давлением, что вызывает поворот управл емых колес и смещение гайки 19, а вместе с ней и золотника 27 в нейтральноеBy turning the nut 19 and the associated vstuviya 26, the spool 27 of the distributor 28 will move from the neutral position, providing a connection between one of the working cavities 3 or 4 with a pressure source and the other with a drain. The piston 2 will begin to move in the axial direction under the action of the fluid under pressure, which causes the steering wheels to turn and the nut 19 to shift, and with it the spool 27 to the neutral
положение, в котором указанные детали будут удерживатьс до тех пор, пока водитель не поверпет рулевое колесо и св занный с ним винт 21 на больший угол.a position in which the said parts will be held until the driver places the steering wheel and the associated screw 21 at a greater angle.
