Abstract

1357106 Four-wheel drives HARRY FERGUSON Ltd 1 July 1971 [18 July 1970 (2) 22 Feb 1971] 34950/70 34952/70 and 5137/71 Heading B7H [Also in Division F2] In a four-wheel drive vehicle, a viscous coupling 11 is provided in the drive to one set of wheels, which wheels are not normally driven by virtue of the gearing, so that should the other set of wheels slip this slip will be restricted and torque transferred to the one set of wheels. As shown the output shaft 32 from the engine drives the planet carrier 29 of an epicyclic differential 28, drive to one set of wheels being from the ring gear 30 via shaft 33 and drive to the other being via sun gear 31, a shaft 37 and a chain drive to the shaft 35 to these wheels. The coupling interconnects ring gear 30 and the sun gear 31. In an alternative embodiment (Fig. 17) the coupling 38 is disposed in the drive to the front wheels as shown, torque only being transmitted thereby when the front wheels spin. An anti-lock braking sensor may also be incorporated (Fig. 18, not shown).
