Problems solved by technology

[0006] However, the power transmission mechanism of the above-mentioned hybrid system has a disadvantage that, in the case of driving only by the driving force of the engine 1, due to the Mechanical loss due to the influence of magnets
In addition, when the stator 17 of the motor 5 is energized in order to offset the load loss, a new electrical loss is generated

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0029] Figure 1 to Figure 4 It shows the first embodiment of the power transmission mechanism of the parallel hybrid electric vehicle of claim 1, and Image 6 Similarly to the conventional example, the arrangement of the driving system of the hybrid system of this embodiment is also in the order of the engine 21, the main clutch (single plate clutch) 23, the motor (motor / generator) 25, the transmission 27, and the main drive reduction gear 29. , all configured on the coaxial. Furthermore, an engine drive shaft system 31 is connected from the main clutch 23 to the transmission 27 , and a propulsion shaft 33 is connected between the transmission 27 and the final reduction gear 19 .

[0030] In addition, in the figure, 35 is a motor output shaft attached to the rotor 37 of the motor 25, which is comprised independently from the said engine drive shaft system 31...

Abstract

Provided is a power transmission mechanism for a parallel hybrid vehicle, which can be applied to a large-size hybrid vehicle. To this end, the power transmission mechanism can smoothly combine and separate input and output powers of a motor and an engine and provide an input and output power combining and separating mechanism with a sufficient strength. The power transmission mechanism comprises a motor output shaft of a motor / generator which is rotatable independently of an engine drive shaft system connecting to a transmission through a main clutch; a motor brake which is provided at one end side of the motor output shaft and which releases / fixes the motor output shaft; a planetary gear mechanism provided between the other end side of the motor output shaft and the engine drive shaft system and comprised of a sun gear provided on the other end side of the motor output shaft, an outer gear provided in the engine drive shaft system and having a gear ratio of 1:1 to the sun gear, a plurality of planetary gears with which the sun gear and the outer gear engage, and a planetary carrier which receives and transmits the revolutions of the planetary gears; and a gear brake which is provided on one end side of the planetary carrier and which releases / fixes the planetary carrier.

Description

technical field [0001] The present invention relates to a power transmission mechanism of a hybrid electric vehicle, in detail, relates to a power transmission mechanism of a parallel hybrid electric vehicle which uses the power of an engine and a motor / generator together. Background technique [0002] As disclosed in Non-Patent Document 1, in commercial vehicles such as trucks, in order to reduce the load on the engine and improve the fuel consumption rate, a parallel hybrid system has been proposed. When driving with the load applied to the engine, the motor is assisted. [0003] like Image 6 As shown, the arrangement of the driving system of the above-mentioned hybrid power system is that all of them are arranged in the coaxial. Furthermore, a rotor 13 of the motor 5 is attached to an engine drive shaft system 11 connected from the main clutch 3 to the transmission 7 , and a propulsion shaft 15 is connected between the transmission 7 and the final reduction gear 9 . ...
