Problems solved by technology

[0007] However, the rotation speed in the motor transmission device 17, especially the rotating element connected to the first motor 10, tends to rotate at a high speed, and when it is inadvertently assembled into the transaxle case, radiated sound is likely to be generated, so the sound vibration cannot be ensured. performance

Embodiment 1

[0037] figure 1 It is a schematic system diagram showing the drive train and its overall control system of the drive system of the hybrid vehicle according to the first embodiment. figure 1 The hybrid vehicle is equipped with an engine 1 and an electric motor 2 as power sources, and the engine 1 is started by a starter motor 3 . The engine 1 is driveably coupled to the driving wheels 5 through a V-belt type continuously variable transmission 4 in an appropriately disconnected manner, and the outline of the continuously variable transmission 4 will be described below.

[0038] The continuously variable transmission 4 is a continuously variable transmission mechanism CVT constituted by a transmission mechanism including a primary pulley 6 , a secondary pulley 7 , and a V-belt 8 wound between these pulleys 6 and 7 . The primary pulley 6 is combined with the output shaft of the engine 1, that is, the crankshaft, through the hydraulic torque converter T / C with a lock-up clutch, an...

Abstract

The drive device of the hybrid vehicle of the present invention has: a transmission which is combined with the engine output shaft of the engine; a final reduction gear which is combined with the transmission output shaft of the transmission; a drive shaft which is combined with the final reduction gear; and a power transmission mechanism which A transaxle case is provided which transmits the rotation of the electric motor to the final reduction gear, houses a transmission, the final reduction gear, and the power transmission mechanism, and has a mounting surface on which the engine and the electric motor are mounted. Further, the transaxle case is composed of a converter case serving as an engine side, a transmission case serving as a transmission side, and an intermediate wall attached to the converter case and partitioning between the transmission case, and the power transmission mechanism is housed in between the converter housing and the intermediate wall.

Description

technical field [0001] The present invention relates to a drive system for a hybrid vehicle equipped with an engine and an electric motor. Background technique [0002] As such a driving device for a hybrid vehicle, for example, a device described in Patent Document 1 is known. The first electric motor 10 of this vehicle is coupled to an output shaft 17 a via a transmission device 17 for electric motors. The motor transmission 17 is constituted by planetary gears, and the first electric motor 10, the output shaft 17a, and the motor transmission 17 are arranged in a row in the axial direction. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: (Japanese) Patent No. 3584680 [0006] The problem to be solved by the invention [0007] However, the rotation speed in the motor transmission device 17, especially the rotating element connected to the first motor 10, tends to rotate at a high speed, and when it is inadvertently assembled into the...
