Abstract
Abstract A non-step transmission is provided with a rotor (17) of which input shaft is connected to a drive source (1), another rotor (19) of which output shaft (19a) is connected to a driving load, a plurality of exciting windings for controlling the inter-coupling-force of said rotors (17, 19), and a control unit (4) for recognizing the condition of operation of a vehicle (2), and determining a gear ratio of the transmission (3). The gear ratio is controlled to be set to the determined value by controlling the exciting winding.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
A non-step transmission (3) comprising: a first rotor (17) at an input side, a second rotor (19) at an output side, a torque transmitting means for transmitting rotational
torque between the above two rotors, and a control unit (4) for controlling the difference
between the rotational speeds of the rotors (17, 19), wherein a rotary shaft (19a) of said rotors (17, 19) is
controlled by providing an output obtained due to the
difference between the rotational speeds to a motor (12)
which rotates according to said first and second rotors
(17, 19).
Claim 2
Dependent Claim
98 words
A non-step transmission comprising: a first rotor (17), a second rotor (19), a first winding for generating torque which acts on each
other between said first and second rotors (17, 19), a second winding for generating torque which acts on
each other between a stator and said first and second
rotors (17, 19), a control unit (4) for determining a gear ratio
according to an operation command value supplied from
the outside, and a power converter for controlling each torque by
suppling independently a current to said first and
second windings so as to take the gear ratio.
Claim 3
Dependent Claim
87 words
A non-step transmission comprising: a rotor (17) of which input shaft is connected to a
drive source (1),
another rotor (19) of which output shaft (19a) is
connected to a driving load (5), a plurality of exciting windings for controlling the
inter-coupling-force of said rotors (17, 19), and a control unit (4) for recognizing the condition of
operation of a vehicle, and determining a gear ratio of
a transmission, wherein the gear ratio is controlled to be set to the
determined value by controlling said exciting winding.
Claim 4
Dependent Claim
149 words
A vehicle having an engine (1), and a transmission for
converting the rotational speed of the engine (1) into
the rotational speed of a drive shaft (5) for driving a
car body, said vehicle further comprising: a first rotor (17) which is rotated by said engine (1), a second rotor (19) for rotating said drive shaft, a motor (12) including a first winding for generating
torque which acts on each other between said first and
second rotors (17, 19), and a second winding for
generating torque which acts on each other between a
stator and said first and second rotors (17, 19), a control unit (4) for determining a gear ratio
according to an operation command value supplied from a
driver, and first and second power converters for controlling each
torque by suppling independently a current to said first
and second windings so as to take the gear ratio.
Claim 5
Dependent Claim
164 words
A hybrid vehicle having an engine (1), an electric power
storing unit (4a), and an energy converting unit for
storing the rotation energy of the engine (1) in said
storing unit (4a) and converting the stored energy into
the torque of a drive shaft (19a) for driving a car
body, said vehicle further comprising: a first rotor (17) which is rotated by said engine (1), a second rotor (19) for rotating said drive shaft (19a), a motor (1) including a first winding for generating
torque which acts on each other between said first and
second rotors (17, 19), and a second winding for
generating torque which acts on each other between a
stator and said first and second rotors, a control unit (4) for determining a gear ratio
according to an operation command value supplied from a
driver, and a power converter for controlling each torque by
suppling independently a current to said first and
second windings so as to take the gear ratio.
