摘要

The weighing scales, to measure the weight imposed by a loaded trailer on the tow bar of the towing vehicle, has a joint (2) to show the angular change between the tow bar (1) and the shaft (4), with a spring (3) to develop a counter force to the force of the loading weight. A sliding pin (5) indicates the weight on the towing link.
