(EN) Torque proportioning differential
Abrégé
(EN)

A torque proportioning differential (10/110) is disclosed for a wheeled vehicle or the like which has a driven carrier (18/112), first and second output members (68,72/138,140), first and second radially outer gears (44,48/122,124), first and second radially inner gears (56,58/126,128), a gear mechanism (26,28/116,118) rotatably mounted on the carrier for cross connecting the outer and inner gears, and first and second coupling devices (78,80/130,134,142,144) for delivering more than 50% and less than 100% of the input torque to the slower output member, with the coupling devices being connected to the output members and at least one of each of the outer and inner gears. Positive drive of each output member is achieved in each direction of rotation of the carrier without a significant degree of energy dissipation.
