ABSTRACT:
Apparatus for mounting between the bed and axle of a truck, or the like, to indicate the weight being carried by the truck as a function of the compression of the suspension system. A sensing member containing a load cell is mounted to the frame of the bad and a contacting member is mounted to the axle. The contacting member is slideably mounted to depress a compression spring as the frame moves towards the axle as a result of an increased load on the truck. The increasing force created thereby on the load cell causes an increase in the signal out of the load cell, which, in turn, is translated into an indication of the corresponding load or weight on the truck. The contacting member is mounted within a sealed housing and movable to a position out of contact with the load cell when not performing its weight function. As a result, the apparatus is resistant to changes in temperature, dirt, moisture, and shock.
