Hybrid drive device and automobile with device mounted thereon

Abstract

A hybrid driving unit in which a first electric motor (20), a second electric motor (23), a transmission (22) and a power splitting planetary gear (21) are disposed in order from the front side (the side of an internal combustion engine) on an axis within a casing member (14). Since the first electric motor (20) and the second electric motor (23) are disposed adjacently to each other, partial cases for storing these first and second electric motors (20) and (23) may be combined, thus facilitating the accommodation for producing the unit in series.

Description

technical field

[0001] The present invention relates to a compound drive device mounted on an automobile and an automobile equipped with the device, and particularly relates to the arrangement of two electric motors, a planetary gear for power distribution, and a speed change device in a case member. Background technique

[0002] In the well-known hybrid drive system installed in automobiles in the past, the engine, generator (first electric motor), and drive (assist) electric motor (second electric motor) are connected to the three elements of the planetary gear unit, respectively. At the same time, the second electric motor is connected to the output shaft, the first electric motor is controlled to continuously control the output torque of the planetary gear unit, and the torque of the second electric motor and the output of the planetary gear are combined as needed. The torque is combined and output to the output shaft, which is the so-called mechanical split type (separa...
