A limited slip differential is adapted for use in self-propelled wheeled vehicles requiring maximum available tractive effort. The differential utilizes a gearless design for differentiation and compact gearing therewith for reliability and increased limited slippage characteristics. The preferred differential embodiment comprises a housing having a slide block mounted therein for relative reciprocation in a first plane perpendicular to a longitudinal axis of the differential. A pair of first gear members, each having teeth formed internally thereon, are disposed on either side of the slide block and are keyed thereto for relative reciprocation in a second plane and longitudinal axis. A pair of second gear members, each adapted for securance to a drive axle and having teeth formed externally thereon, are rotatably mounted in the housing. Each second gear meshes with a respective first gear and has a lesser number of teeth to form a cycloidal gear set whereby each first gear will orbit in a circular path about the longitudinal axis of the differential, allowing its meshing second gear to rotate in a direction opposite thereto. A cross-over control means is pivotally interconnected between the slide block and first gears to assure that the drive axles will rotate in opposite directions during all phases of differentiation. |
