ON-BOARD WEIGHING SYSTEM

摘要

The invention relates to a suspension (20) in accordance with a first embodiment of the invention that permits reducing the number of load cells (14) incorporated in a suspension (20) of a vehicle or a trailer such as a semi-trailer to be towed by a towing vehicle. In accordance with a particular embodiment of the invention reduction of the number of load cells (14) is accomplished through the use of pivot joints (34) (that pivotally attach the suspension rockers (32) to the hangers 26) of reduced friction. In particular embodiments of the invention, the number and location of the low and lower friction pivot joints (34) may be chosen such as to increase the accuracy of measurement of the load cells. The invention also relates to load cell pins (62) for defining the pivot joint (34) that pivotally attaches rockers (32) to hangers (26) of the suspension (20).
