Load deflecting degree computing apparatus and carrying weight computing

A correction winding in which an alternating current flows attributable to magnetic flux generated in an exciting winding when an alternating current is allowed to flow in the exciting winding, is provided for a sensing device. In a state where the characteristics of the sensing device are not changed, electric power is supplied to the exciting winding so that a reference value, which is a digital value of the difference in the potential between the two ends of the correction winding detected by the correction detection circuit, is stored in a RAM of a microcomputer by operating a setting switch, and then divided with a digital value of the difference in the potential between the two ends of the correction winding detected by the correction detection circuit. A value Vso/Vs, which is a result of the division, is used to multiply the digital value of the difference in the potential between the two ends of the detection winding detected by the detection circuit.

Load sensing device with load detection signal correction apparatus and

A vehicle load measuring device includes a sensing element for detecting a strain to measure the load of a vehicle, in which the sensing element is formed in a pin shape, and a device for supporting a suspension of the vehicle, in which a hole is formed in the supporting device and the sensing element is fitted into the hole, wherein the load of the vehicle is measured based on the strain detected by the sensing element produced in response to the load supported by the supporting device, and a positioning groove being formed on a surface of the device for supporting a suspension, wherein when the device for supporting a suspension connects a suspension with a bracket on the vehicle the device for supporting a suspension is positioned by use of the positioning groove, thereby determining the direction of the load to be applied to the sensing element and preventing the device for supporting a suspension from moving in a predetermined direction with respect to the bracket. The supporting device can be a trunnion shaft or a shackle pin. Also, the sensing element includes a magnetic strain sensing element formed from a magnetic material in a plate-like shape having a plurality of holes and having a coil wound in an intersecting manner through the plurality of holes.

Load measuring device for a vehicle

A vehicle load measuring device comprises a slide plate mounted on the upper surface of an axle case, a load of the vehicle applied through a leaf spring onto the slide plate, the slide plate including a setting portion at an inner surface; and a sensing member fitted into and fixed to the setting portion.
