Problems solved by technology

Although these structural elements can be added to the structure of the conventional engine-vehicle transmission, it increases the cost corresponding to the synchronous clutch for the motor and the four gears.
Also, the interlock mechanism to prevent double engagement of multiple gears becomes complicated
In addition, since the number of gears arranged side by side on the input shaft and the output shaft increases, the overall length of the transmission in the axial direction increases, so the constraints on vehicle mounting become greater.

Embodiment Construction

[0025] refer to Figure 1 to Figure 4 A first embodiment for carrying out the present invention will be described. figure 1It is a schematic diagram showing a power transmission path of the hybrid vehicle transmission 1 according to the first embodiment of the present invention. The hybrid vehicle transmission 1 is mounted on an FF type hybrid vehicle. The hybrid vehicle transmission 1 selects any one of five forward speeds and one reverse speed, and shifts and outputs the engine torque of the engine 91 . Furthermore, the hybrid vehicle transmission 1 outputs the motor torque of the motor 93 directly or via the above-mentioned shift speed. The output side of the hybrid vehicle transmission 1 is rotatably connected to a left drive front wheel 95 and a right drive front wheel 96 via a differential device 94 . The transmission 1 for a hybrid vehicle includes an input shaft 2 , an output shaft 3 , a transmission gear train 4 , an engine-side coupling device 5 , a motor-side cou...

Abstract

A transmission for hybrid vehicle includes a change-speed gear assembly (4), an engine-side connector (5), and a motor-side connector (6). The change-speedgearassembly (4) includes drive gears and driven gears making change-speed stages. A specific drive gear (45D) of the drive gears, and a specific driven gear (45F) of the driven gears, making a specific change-speed stage (e.g., the fifth-speed change-speed stage) of the change-speed stages, are made switchable between the idling state and the rotary connection state. The engine-side connector (5) switches the other drive gears and driven gears, making the other change-speed stages, between the idling state and the rotary connection state, respectively. The motor-side connector (6) includes a motor-side drive gear (61) meshing with a motor-side driven gear (45D) doubled as the specific drive gear (45D). The motor-side connector (6) switches the specific drive gear (45D), and the specific driven gear (45F) between the idling state and the rotary connection state, respectively.

Description

technical field [0001] The present invention relates to a transmission used in a hybrid vehicle having an engine and a motor as drive sources. Background technique [0002] Various power transmission mechanisms suitable for a hybrid vehicle having an engine and a motor as drive sources have been proposed. For example, the power transmission mechanism of Patent Document 1 includes: a stepped transmission having an input shaft connected to the engine and an output shaft connected to the driving wheels; a first gear and a second gear provided on the rotating shaft driven by the electric motor; And a switching mechanism for selectively switching the connection mode of the electric motor. The switching mechanism selectively switches between an output shaft connection mode in which the first gear meshes with the output shaft gear, and an input shaft connection mode in which the second gear meshes with the input shaft gear. As a device for selectively switching, a synchronous clu...
