Embodiment Construction

[0075] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 shows the schematic plan view of the FR automobile (embodiment 1) equipped with the hybrid driving device of the present invention, 1 1 Indicates that it is equipped with a hybrid drive unit 6 1 FR type car. the car 1 1 The car body 2 is suspended on the left and right front wheels 3, 3 and the left and right rear wheels 25, 25. At the front part of the car body 2, the internal combustion engine 5 is mounted on the crankshaft in the front-rear direction through a rubber mount.

[0076] Hybrid Drive 6 1 , same as above, aligned with the crankshaft from the engine 5 side and arranged on the same axis, the first electric motor (electric motor for control) 7, the planetary gear mechanism 9 for power distribution, and the second electric motor (electric motor for driving) 10 are sequentially arranged 1 , further on this basis in the second motor 10 1 The transmissi...

Abstract

An output of an internal combustion engine is transmitted to an output shaft by controlling a control motor to change a speed without speed steps, in a power distribution planetary gear. An output of a drive motor is input to the output shaft by changing the speed into two-step decelerated rotation by means of an automatic transmission. The transmission produces a desired torque by decelerating the speed in a large degree when a vehicle speed is low, and produces a desired number of revolutions by decelerating the speed in a small degree when the vehicle speed is high.

Description

technical field [0001] The present invention relates to a hybrid drive device mounted on an automobile and an automobile equipped with the hybrid drive device, and specifically relates to an output structure of a drive (assist) motor. Background technique [0002] In the past, as a hybrid drive device, the output of the engine was distributed by the planetary gear mechanism to the control motor and the driving output side. By letting the motor be mainly controlled as a generator, the output torque of the above-mentioned planetary gear mechanism can be controlled steplessly. Further, according to It is necessary to combine the torque of other drive (assist) motors with the output torque of the above-mentioned planetary gear mechanism and then output it to the output shaft, which is the so-called mechanical distribution method (separate type or dual motor type). Such a device is mounted on a car (registered trademark named プリゥス) for practical use. [0003] The hybrid drive de...
