PORTABLE DEVICE FOR DETERMINATION OF WEIGHT OF VEHICLES Russian patent published in 2009 - IPC G01G19/08 

FIELD: physics, measuring.

SUBSTANCE: device consists of basic frame with coupling device, two active hydroseats, one of which immobile, and other hydroseat has possibility of travel concerning basic frame, hydropump, data unit of measuring of pressure toting pressure in both hydroseats. Thus hydroseats and the coupling device are fastened to basic frame, and transformer of signal of the data unit of measuring of pressure is entered into the measuring block. At measuring of weight pistons of hydroseats move synchronously at the expense of synchronous translational motion plungers, creating working pressure in both independent mains of the hydroseats, one blanket device of the mechanism of travel. Thus both hydroseats are active, and the blanket device of the mechanism of travel can be executed in the form of piston of the hydrocylinder, pneumocylinder piston, lever mechanism or screw pair.

EFFECT: increase of measurement accuracy of weight and device weight reduction.
