Differential with integrated torque vectoring
Abstract:
A torque vectoring differential includes a pair of planetary gear assemblies having a common planet gear carrier which is driven from the output of a transmission. Each of the planetary gear assemblies include a ring gear that may be individually and selectively grounded (braked) to a stationary housing by a friction brake and a sun gear that is coupled through an axle to a respective drive wheel. Selective activation of the brakes controls the distribution, i.e., vectoring, of torque to each of the drive wheels. Each planetary gear assembly includes elongated planet gears which mesh not only with their respective sun and ring gears but also with the planet gears of the other planetary gear assembly.
