Problems solved by technology

[0007] However, in the above-mentioned compound drive device, the casing member is divided into multiple parts, and the axis center of the casing member is shifted.
In this way, the support accuracy of the respective rotors of the first electric motor and the second electric motor is lowered, and there is a possibility that vibration may be generated due to the vibrating rotation of the shaft.
In addition, the first and second electric motors are housed in different casing parts, and the casing parts need to be reinstalled for the two different electric motors. Therefore, when the hybrid drive device is FRized, it is disadvantageous for the above-mentioned units. serialization, etc.

no. 1 Embodiment approach

[0071] figure 1 An example of an automobile according to the present invention, that is, an automobile 1 equipped with a hybrid drive device according to the present invention is shown. The car 1 shown in the same figure is a FR (front engine, rear wheel drive) type car, and the same figure is a plan view showing its approximate structure. In addition, in an actual automobile, the arrow F direction in the figure is the front side, and the arrow R direction is the rear side.

[0072] The automobile 1 shown in the figure has a vehicle body 4 supported by left and right front wheels 2, 2 and left and right rear wheels 3, 3 as driving wheels. The internal combustion engine 5 is mounted on the front portion of the vehicle body 4 via a rubber mount (not shown), and a crankshaft 6 serving as an output shaft thereof faces in the front-rear direction. In addition, in the same figure, the output shaft formed by the rear protrusion part of a crankshaft is the crankshaft 6 shown in fig...

no. 2 Embodiment approach

[0139] Next, as a piggyback on figure 1 As another example of the hybrid drive device 7 according to the present invention in the automobile 1 shown, the hybrid drive device 7B according to the present embodiment will be described. First, refer to Figure 7 The skeleton diagram of , illustrating the general situation of the compound drive device 7B as a whole, and then refer to Figure 8 , describe the specific structure in detail. In these figures, the arrow F direction is the front side of the vehicle body (internal combustion engine side), and the arrow R direction is the vehicle body rear side (differential gear side).

[0140] Such as Figure 7 As shown, the compound drive unit 7B moves from close to figure 1 From the internal combustion engine 5 side, that is, from the front side to the rear side, a first electric motor 20, a second electric motor 23, a planetary gear 21 for power distribution, and a speed change device 22 are sequentially arranged. These are acco...

no. 3 Embodiment approach

[0202] Next, as a piggyback on figure 1 An example of the compound drive device 7 relevant to the present invention on the shown automobile 1, with reference to Figure 12 The skeleton diagram of FIG. 2 illustrates the hybrid drive device 7C of this embodiment. In these figures, the arrow F direction is the front side of the vehicle body (internal combustion engine side), and the arrow R direction is the vehicle body rear side (differential gear side).

[0203] Such as Figure 12 As shown, the compound drive unit 7C moves from close to figure 1 From the internal combustion engine 5 side, that is, from the front side to the rear side, a planetary gear 21 for power distribution, a first electric motor 20, a second electric motor 23, and a speed change device 22 are sequentially arranged. These are accommodated in housing part 14 (see figure 1 ) on the inner side of the first axis 13 (around the first axis 13) and arranged in order along the first axis 13. Next, the plane...

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...
