Abstract
1. Каретка вил (100) для вилочного погрузчика, содержащая несущую раму (7) с по меньшей мере двумя захватами (1) для груза, которые расположены на несущей раме (7) с возможностью перемещения для изменения расстояния между ними, причем каждому захвату (1) для груза придан дифференциальный цилиндр (4, 4') с гидравлическим приводом для обеспечения движения перемещения, отличающаяся тем, что кольцевой объем (8) на стороне штока поршня одного дифференциального цилиндра (4') соединен с объемом (10) на стороне поршня другого дифференциального цилиндра (4), причем кольцевая поверхность (18) на стороне штока поршня одного дифференциального цилиндра (4') находится в заданном отношении к поверхности (19) на стороне поршня другого дифференциального цилиндра (4). ! 2. Каретка вил по п.1, отличающаяся тем, что соотношение составляет 1:1. ! 3. Каретка вил по п.1 или 2, отличающаяся тем, что дифференциальные цилиндры (4, 4') по меньшей мере в одном из конечных положений содержат перепускное устройство (16, 16'). ! 4. Каретка вил по п.3, отличающаяся тем, что перепускное устройство (16, 16') включает в себя байпасный трубопровод (17, 17'), сопротивление потоку которого велико, по сравнению с сопротивлением потоку объемов рабочих сред для гидравлики системы дифференциальных цилиндров. ! 5. Напольное транспортное средство, содержащее каретку вил по одному из пп.1-4. 1. A fork carriage (100) for a forklift truck containing a carrier frame (7) with at least two grippers (1) for cargo, which are located on the carrier frame (7) with the possibility of movement to change the distance between them, and each grip ( 1) for the load, a differential cylinder (4, 4 ') with a hydraulic drive is attached to provide movement movement, characterized in that the annular volume (8) on the side of the piston rod of one differential cylinder (4') is connected to the volume (10) on the side of the piston another differential cylinder (4), m, the annular surface (18) on the side of the piston rod of one differential cylinder (4 ') is in a predetermined relation to the surface (19) on the side of the piston of another differential cylinder (4). ! 2. The fork carriage according to claim 1, characterized in that the ratio is 1: 1. ! 3. The fork carriage according to claim 1 or 2, characterized in that the differential cylinders (4, 4 ') at least in one of the end positions contain a bypass device (16, 16'). ! 4. The fork carriage according to claim 3, characterized in that the bypass device (16, 16 ') includes a bypass pipe (17, 17'), the flow resistance of which is large compared with the resistance to the flow of working media volumes for differential system hydraulics cylinders. ! 5. A floor vehicle containing a fork carriage according to one of claims 1 to 4.
