Claims20
A fifth wheel hitch assembly in which said fifth wheel hitch assembly is supported by transverse beams being susceptible to horizontal and vertical deflections, at least one of said transverse beams comprising a sensor having a transducer for measuring said horizontal deflection at the center of said beam and a transducer for measuring said vertical deflection at the center of said beam, said beam comprising two outer parts and an inner part connecting said outer parts, said transducers being placed on said inner part, said inner part serving to actuate said transducers.
A sensor comprising a beam susceptible to horizontal and vertical deflections;
- a transducer for measuring said horizontal deflection at the center of said beam;
- and a transducer for measuring said vertical deflection at the center of said beam;
- said beam comprising two outer parts and an inner part connecting said outer parts, said transducers being placed on said inner part, said inner part serving to actuate said transducers.
