Problems solved by technology

[0012] In the dual-clutch transmission having the above-mentioned motor, there is a problem that the motor cannot be driven as an electric motor when the battery is not charged, or the remaining capacity of the battery is low, and therefore, the clutch connection cannot be suppressed. The rotational variation of the driving force

Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a schematic diagram showing a structural example of a vehicle including a transmission 4 according to an embodiment of the present invention.

[0038] A vehicle 1 of the present embodiment is a vehicle of a hybrid vehicle having an engine 2 and a motor 3 as drive sources. This vehicle 1 has: an inverter 20 for controlling the motor 3; a battery 30 for supplying electric power to the motor 3; a transmission 4 for changing the rotational speed of the driving force from a driving source to a desired rotational speed; and a differential mechanism 5 for The drive force transmitted from the transmission 4 is distributed to the left and right drive wheels WL, WR; the left and right drive shafts 6L, 6R transmit the respective drive forces distributed by the differential mechanism 5 to the left and right drive wheels WL, WR; and the left and right drive w...

Abstract

A transmission capable of suitably suppressing rotation fluctuation of driving force due to fastening of a second clutch, without using torque of a motor in starting a vehicle with one driving gear belonging to a second gear group is provided. A driving gear belonging to first gear group (71, 43, 45, 47) is pre-shifted to an inside main shaft (IMS), and one driving gear belonging to a second gear group (42, 44, 46) is shifted to a secondary shaft (SS) to fasten a second clutch (C2). Preferably, for the driving gear to be pre-shifted, a driving gear of a first-speed stage or third-speed stage is selected, and for the drive gear to be shifted, a driving gear of a second-speed stage is selected. Also, a motor (3) is connected to the downstream side of a first clutch (C1) of the inside main shaft (IMS) through a planetary gear mechanism (70).

Description

technical field [0001] The present invention relates to a dual-clutch transmission (two-clutch transmission), which has two input shafts to which driving force is input from a driving source and two clutch mechanisms for separating and engaging driving force between the driving source and the input shaft. Background technique [0002] As a basic framework, a dual clutch transmission has: a first input shaft on which a plurality of drive gears (hereinafter also referred to as "transmission gears"; The input shaft, on which a plurality of drive gears related to the even-numbered transmission stages are arranged in a relatively rotatable manner; the first synchronous mechanism or the second synchronous mechanism that synchronously engages each drive gear with the first input shaft or the second input shaft to which it belongs. a synchronous mechanism; an output shaft on which is provided with a plurality of driven gears meshing with both the drive gears of the odd-numbered tran...
