    摘要: A reduced weight fifth wheel (10) generally mountable on a tractor (21) for coupling between a tractor (21) and a trailer (25), which fifth wheel (10) has approximately the same bearing surface area, a more continuous surface area by elimination of a lever-bar pin port (76) in the bearing surface, thinner support ribs and smaller fillets, a shorter longitudinal length with a wider kingpin receiving slot (58) for receipt of a trailer kingpin (23), with a locking-jaw mechanism (77) having a redesigned lever-bar pin and pin-receiving port to enable reduction of the weight and to enhance producing casting practices.
