摘要:
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.
