Abstract:
A torque-proportioning fully-locking differential, comprising:(a) a stationary hollow differential housing;(b) a cylindrical carrier rotatably mounted within said housing for rotation about a given axis, said carrier having end portions containing aligned first bores collinear with said given axis;(c) a pair of annular side gears rotatably mounted within said bores, respectively, said side gears being adapted for splined connection with the ends of a pair of aligned output shafts that extend through corresponding openings contained in said housing, respectively;(d) pairs of helical pinion gears rotatably mounted within corresponding second bores contained in said carrier for transmitting torque from said carrier to said side gears, respectively;(e) coupling means operable between disengaged and engaged conditions to lock a first one of said side gears to said carrier; and(f) operating means arranged externally of said housing for operating said coupling means between said disengaged and engaged conditions, respectively.
