2 more elements
A transmission comprising:
- a plurality of differential mechanisms in each of which a difference in the number of rotation between an input shaft thereof and an output shaft thereof is controlled by a motor;
- wherein said input shafts of said plurality of differential mechanisms are a first common shaft, and said output shafts of said plurality of differential mechanisms are a second common shaft.
A vehicle comprising:
- an engine for generating drive energy for driving said vehicle;
- and
- a transmission for changing the speed of rotation of said engine and transmitting the rotational drive force thus speed-changed to a wheel and having
- first and second differential mechanisms, each of which takes at least a drive force generated by said engine as an input force and takes a drive force for driving said wheel as an output force;
- and
- first and second motors for controlling said first and second differential mechanisms, respectively.
3 more elements
A vehicle comprising:
- an engine for generating drive energy for driving said vehicle;
- first and second planetary gears each of which is composed of a sun gear, a planetary element, and a ring gear;
- and
- first and second motors for controlling said sun gears of said first and second planetary gears, respectively;
- wherein one of said planetary element and said ring gear of each of said first and second planetary gears is connected to an input shaft driven by said engine and the other of said planetary element and said ring gear is connected to an output shaft for driving a vehicular body.
