Load measuring device for a vehicle

A vehicle load measuring apparatus comprising:

• a sensing element for detecting a strain at a position where said sensing element is located on a vehicle to measure the load of the vehicle, said sensing element being formed in a pin shape;
• and
• a shackle pin for connecting a shackle, for supporting a suspension of the vehicle, with a bracket mounted on a load frame of the vehicle, a hole being formed in the central portion of said shackle pin, and said sensing element being fitted into said hole, and a positioning groove being formed on a surface of said shackle pin, wherein when said shackle pin connects said shackle with said bracket on the load frame said shackle pin is positioned by use of the positioning groove, thereby determining the direction of the load to be applied to said sensing element and preventing said shackle pin from rotating with respect to said bracket.

A vehicle load measuring apparatus s claimed 5, wherein said sensing element is comprised of a magnetic strain sensing element formed from a magnetic material in a plate-like shape a plurality of holes and having a coil wound in an intersecting manner through said plurality of holes.

A vehicle load measuring device comprising:

• a sensing element for detecting a strain to measure the load of a vehicle, said sensing element being formed in a pin shape;
• and
• means for supporting a suspension of the vehicle, a hole being formed in said supporting means and said sensing element being fitted into said hole, wherein the load of the vehicle is measured based on the strain detected by said sensing element produced in response to the load supported by said supporting means, and a positioning groove being formed on a surface of said means for supporting a suspension, wherein when said means for supporting a suspension connects a suspension with a bracket on the vehicle said means for supporting a suspension is positioned by use of the positioning groove, thereby determining the direction of the load to be applied to said sensing element and preventing said means for supporting a suspension from moving in a predetermined direction with respect to said bracket.
