    1509687 Weighing device HAENNI & CIE AG 11 July 1975 [17 July 1974] 29342/75 Heading G1W A weighing device comprises a base 40, a plurality of elastically deformable tubular spring elements 37 on the base, the elements having an elliptical crosssection with the smaller axis extending perpendicular to the base, a load platform 38 resting on the elements 37, and a volume gauge 52 connected to the interiors of the elements 37, the elements 37 being filled with liquid and the gauge 52 indicating the weight induced displacement of liquid out of the elements. Each element 37 may enclose a bar (39) which has a coefficient of expansion less than that of the liquid to provide temperature compensation.

    专利说明:

    The scientific research institutes are one of the other and have in cross section the shape of an ellipse, the small axis of which is located along the line of action of the measured force.
    In each tubular element 1, a rod element 2 is installed, which functions as a spring limiting element and as a link for reducing the amount of fluid contained in the tubular spring. Each such element 2 is made of a material with a small thermal expansion compared with MeHeHTON; 1, to substantially compensate for the effect of temperature changes on expansion or contraction of the transfer fluid.
    The dynamometer also contains a power-transmitting element 3. and a flat platform 4, which can be laid on any flat base 5. On three sides of the platform 4 by means of pins 6 or similar fasteners fastened flat flat rods 7.8 and 9, the thickness of which exactly corresponds to the small the outer diameter of the elliptical cross section of element 1. Along the fourth side of the platform. 4 in a similar way, the carrier plate 10 is fixed. The tubular spring elements 1 lie on a flat platform 4, and the force-bearing element 2 lying on the element 1 is fixed on the platform 4 by means of screws 11, which are pierced; rods 7.8 and 9 and plate 10. On top of the elements 1, they are tightly closed and the pipes 12 and 13 pass through them. The pipe 12 is connected through the pipe 14 with a mesosou 15 .slow plate 10, in which the device 16 is rigidly fixed. serving to measure and indicate the volume of the transmission fluid displaced from the elements 1 in the process of measuring the force.
    All the space of the system, filled with the transfer fluid, including the elements .1, Tpy6t.i 12,13, 14 and Glostozo 15 must be carefully freed from air.
    A tubular yoke 17 is also fixed to platform 4, which is intended to hold a measuring device on it.
    . The dynamometer works as follows.
    The measured force P from the wheel of the vehicle being weighed is applied to any place of the power-transmitting element 3, which transmits this force to the tubular
    spring elements 1. The deformation of the latter entails a change in the volume filled with fluid.
    The volume of fluid displaced from the elements 1 is transferred through 5 pipes 12 and 14 to a measuring device 16, which is a volume measuring device.
    Since the tubular spring Q: elements 1 have the same spring characteristic, the result from measuring does not depend on whether the force acts uniformly on all or unevenly on one element 1, f
    depended on the fluid pressure, and depended only on the deformation of the spring elements 1, i.e. did not depend on the point of application of the measured force, as a measuring instrument, a device for use was used. measurement of volume, and a change in volume of elements 1, sufficient for a measuring instrument, is provided by an elliptical section of these elements.
