Problems solved by technology

However, in the planetary gear mechanism of the hybrid drive device configured as described above, the relative speed (rotation difference) between the sun gear and the ring gear is relatively large, so the rotation difference (slippage) of the friction material in the state where the clutch is not engaged speed) increase
Therefore, the friction loss in the clutch has an influence on the transmission efficiency of the hybrid drive device.

Abstract

A hybrid drive apparatus is provided and enables efficient energy regeneration by the motor generator by separating the power transmission path through which the driving force from the engine is transmitted, from the power transmission path between the motor generator and the drive wheels, and also makes it possible to achieve a variety of driving modes while improving power transmission efficiency. In a hybrid drive apparatus (1) having an engine (10), a motor generator (20), and a planetary gear mechanism (30) in which the output shaft (21) of the motor generator (20) is coupled to a sun gear (S), the output shaft (11) of the engine (10) is coupled to a ring gear (R), and the input shaft (42) of a continuously variable transmission mechanism (40) is coupled to a carrier (C), the hybrid drive apparatus (1) includes a first clutch (C1) that can switch engagement / disengagement between the output shaft (11) of the engine 11 and the ring gear (R), a second clutch (C2) that can switch engagement / disengagement between the carrier (C) and the ring gear (R), and a third clutch (C3) that can switch engagement / disengagement on the input shaft (42) of the transmission mechanism (40).

Description

technical field [0001] The present invention relates to a hybrid drive device including an engine that generates power by combustion of fuel, and a motor generator that functions as an electric motor and a generator. Background technique [0002] Conventionally, for example, as shown in Patent Documents 1 and 2, there is a hybrid drive device for a vehicle that includes an engine that generates power by burning fuel, and a motor generator that functions as an electric motor and a generator. functions; a planetary gear mechanism (planetary gear) that synthesizes and outputs driving force input from the engine and a motor generator; and a speed change mechanism that can change the speed of rotation based on the driving force from the planetary gear mechanism and output it to the drive wheel side. In the hybrid drive device described in Patent Document 1, the output shaft of the engine is connected to the ring gear of the planetary gear, the output shaft of the motor generator...
