Embodiment Construction

[0022] Hereinafter, some exemplary embodiments will be described with reference to the drawings.

[0023] figure 1 Among them, F means front, A means back, R means right, L means left, U means up, and D means down. In the following description and appended claims, figure 1 The direction passing through the front and rear corresponds to the length direction, the direction passing through the left and right corresponds to the width direction, and the direction perpendicular to both corresponds to the height direction. These differences are only for convenience of description, and implementations in which orientations are changed arbitrarily can be realized.

[0024] The power transmission device of this embodiment is used to transmit torque in three directions between a first power source (electric motor), a second power source (internal combustion engine including a generator), and an axle, and can be applied to hybrid power, for example. car. figure 1 The example shown in ...

Abstract

A power transmission device is provided, and outputs torque from a first power source and a second power source to an axle. The power transmission device includes: a first drive shaft coupled to the first power source; a second drive shaft coupled to a second power source; a differential coupled to the axle; a gear set that couples the first drive shaft and the differential gear; a clutch coupled with the second drive shaft gear and detachably connecting the second drive shaft to the differential; a housing provided with side walls and peripheral walls, the side walls rotatably supporting at least the first drive shaft, the second drive shaft, the differential, and the clutch substantially parallel to the width direction, the peripheral walls being integrated with the side walls and being separable in the width direction, and the peripheral walls coupled to each other surrounding the differential, the gear set, and the clutch; a central projection independent from the peripheral wall and coupled to the side wall; and a rib continuous from the central protrusion and extending toward the clutch, and facing the differential.

Description

technical field [0001] The following disclosure relates to a power transmission device for transmitting torque to an axle in a vehicle combining two or more electric motors or internal combustion engines. Background technique [0002] In recent years, vehicles combining two or more power sources have appeared on the market in order to improve energy efficiency. A typical example thereof is a so-called hybrid vehicle. The output of the internal combustion engine is used not only to drive the axle, but also to charge the battery. At this time, the motor functions as a generator, receiving a part of the output of the internal combustion engine to generate electricity. Also, in many cases, when the vehicle is decelerating, the motor also functions as a generator and regenerates the inertial energy of the vehicle as electric power. That is, torque needs to be interchanged in three directions between two or more power sources and axles. A transmission capable of such power tran...
