US 12,371,100 B2 · Three-dimensional monitoring system for kingpin on fifth wheel

Abstract

“THREE-DIMENSIONAL MONITORING SYSTEM FOR KINGPIN ON FIFTH WHEEL” describes an invention patent, for a monitoring system of Kingpin/Fifth Wheel articulation presented on trucks, with a great applicability for autonomous steering systems and vehicle dynamics control. This system allows the precise monitoring of translational, rotational movements and the relative accelerations of the king pin (5) in relation to the fifth wheel (3) on the X, Y and Z axes, totaling measurements in six degrees of freedom. The present patent presents two ways to make this monitoring of the three-dimensional position of the kingpin (5): The first through a set of sensors (6) accelerometers and gyroscope integrated to an electromagnet (4) that when electrified, is coupled to the king pin (5) by magnetic attraction. The second mode through a reference device (20) that is magnetic, identifiable, independent and easy to apply to the kingpin (4).

Dependent claims

A “THREE-DIMENSIONAL MONITORING SYSTEM FOR KINGPIN ON FIFTH WHEEL” characterized by a fifth wheel monitoring system for detecting and monitoring six degrees of freedom of movement of a king pin relative to a fifth wheel, including:

the king pin's translational displacements and clearances (TX, TY, TZ) on X, Y, and Z axes only relative to the fifth wheel;
and
the king pin's rotational movements (RX, RY, RZ) on the X, Y, and Z axes only relative to the fifth wheel;
wherein the fifth wheel monitoring system comprises two devices for a comparative reading and measurement:
an electronic measurement device only present and fixed on the fifth wheel, and
a measured reference device only attached to the king pin.
