no. 1 Embodiment approach

[0078] 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.

[0079] 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

[0134] 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).

[0135] 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 planetary gear 21 for power distribution, a first electric motor 20, a speed change device 22, and a second electric motor 23 are sequentially arranged. These are accomm...

no. 3 Embodiment approach

[0189] Next, as a piggyback on figure 1 Another example of the hybrid drive device 7 according to the present invention in the automobile 1 shown is a description of the hybrid drive device 7C according to the present embodiment. First, refer to Figure 12 The skeleton diagram of , illustrating the general situation of the compound drive device 7C as a whole, and then refer to Figure 13 , 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).

[0190] Such as Figure 12 As shown, the compound drive unit 7C moves from close to figure 1From the internal combustion engine 5 side, that is, from the front side to the rear side, the second electric motor 23, the speed change device 22, the planetary gear 21 for power distribution, and the first electric motor 20 are sequentially arranged. These ...

Abstract

A connection portion (14d) at a front end portion of a case member (14) is connected to an internal combustion engine, and the case member is mounted on a portion (4a) of a vehicle body using a mount portion (installation portion) (14c) at a rear end portion of the case member (14). Further, a second electric motor (23), a heavy object, is disposed at the rearmost end portion of a line where a first electric motor (20), a planetary gear (21) for power distribution, a second electric motor (23), and a speed changer (22) are arranged on one shaft (13) of the case member (14). This suppresses vibration occurring in the case member (14).

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 a well-known hybrid drive system mounted on a car in the past, the engine, generator, and drive (auxiliary) electric motor are respectively connected to the three elements of the planetary gear, and the drive electric motor is connected to the output shaft. Control the generator to control the output torque of the planetary gear unit steplessly, and combine the torque of other driving electric motors with the output torque of the planetary gear to output the output shaft as needed, which is the so-called Combined drive unit with mechanical distribution method (separate type or 2-motor type). [0003] Among the above-mentioned compound drive devi...
