FLUCTUATING GEAR RATIO LIMITED-SLIP DIFFERENTIAL ASSEMBLY

摘要

For the purpose of providing a differential with wide range of variable gear ratio and high level of locking coefficient, the present invention concerns a limited slip differential of variable gear ratio type. The periodic change of gear ratio between planet pinions and side gears results in the torque distribution on both the side gears being a periodic function of the rotating angle of the planet pinions thereby limiting the slip on a single wheel. The present device includes a differential case containing a cross shaft or a simple shaft and the planet pinions/side gears assembly of variable gear ratio. In operation, the gear ratio between planet pinions and side gears varies with the period of at least two pitches. The number of pitches ...
