Claim 1
Independent Claim
324 words
A torque control system for a vehicle, said system being provided, between a first rotary output shaft (13;6A) and a second rotary output shaft (14;6B) in said vehicle, with: input means (8A;3A) to which torque is inputted from an engine; a differential mechanism (8;3) for transmitting said torque, which has been inputted from said input means (8A; 3A), to said first rotary output shaft (13;6A) and said second rotary output shaft (14;6B) while permitting a differential motion between said first rotary output shaft (13;6A) and said second rotary output shaft (14;6B); and a torque transmission mechanism (9A,9B,9C,9D,9F,9G; 5A,5B,5C,5D,5F,5G) having a speed change mechanism (30;10; 31;32;60) for changing a rotational speed of one of said first rotary output shaft (13;6A) and said second rotary output shaft (14;6B) and a clutch (12;42;60;93;94) arranged between said input means (8A;3A) and output means (30E;10E; 31A;32A;60C) of said speed change mechanism (30;10;31;32;60) and being capable of controlling a quantity of torque to be transmitted, said torque transmission mechanism being capable of controlling the state of transmission of the torque to control the distribution of said torque to said first rotary output shaft (13;6A) and said second rotary output shaft (14;6B), characterised in that said speed change mechanism (30;10;31;32;60) is set at such a speed ratio that: the high/low relationship between a rotational speed of said output means (30E;10E;31A;32A;60C) and that of said input means (8A;3A) in said speed change mechanism when a rotational speed of said first rotary output shaft (13;6A) and that of said second rotary output shaft (14;6B) are equal to each other and the high/low relationship between a rotational speed of said output means (30E;10E;31A;32A;60C) and that of said input means (8A;3A) in said speed change mechanism (30;10) when a difference between the rotational speed of said first rotary shaft (13;6A) and the rotational speed of said second rotary shaft (14;6B) becomes the greatest while said vehicle is cornering at a maximum turning rate, remain unchanged.
