Embodiment approach

[0021] According to an exemplary embodiment of the present invention, an unbalance module is assembled into a speed reducer of a conventional engine-driven electric vehicle, so as to generate rumble in vehicles such as an engine-driven electric vehicle, a hybrid vehicle, and the like.

[0022] reducer for electric vehicles, such as Figure 4 As shown, it includes an input gear 440 connected with the drive motor 400 and thereby rotatable; an output gear 460 cooperating with the input gear 440 and receiving power from the input gear 440; an output shaft 450 rotated by power; an output shaft gear 470 connected to the output shaft 450 and formed at a predetermined interval from the output gear 460 and parallel to the output gear 460 ; and a differential gear 480 engaged with the output shaft gear 470 .

[0023] The power transmitted to the differential gear 480 by the speed reducer is transmitted to the transmission shaft 490 connected to the differential gear 480 , and the power ...

Abstract

The present invention relates to a decelerator for generating a booming sound. In particular, the present invention includes a shaft connected with a motor; an input (first) gear engaged in the input shaft, and an output (second) gear mated with the input gear. The motor controls the vehicle speed and delivers the torque of the output (second) gear which is characterized in that output gear further includes an unbalanced drive (third) gear installed on the shaft spaced a predetermined distance from the input (first) gear. Further, an unbalanced driven (fourth) gear is mated with the unbalanced drive (third) gear, and an unbalanced module, having an unbalanced mass, is connected with the unbalanced driven (fourth) gear.

Description

technical field [0001] The invention relates to a vehicle speed reducer driven by an electric motor. More particularly, the present invention relates to a speed reducer for generating rumble, which is installed with an unbalance module having an unbalance mass, and generates rumble by rotating the unbalance module. Background technique [0002] In electric and fuel cell vehicles as environmentally friendly vehicles that are currently being developed, electric motors generate drive torque instead of ordinary engines, and electric vehicles have a structure that converts torque and rotation through a speed reducer with an appropriate gear ratio speed thereby transmitting drive torque to the vehicle propshaft. [0003] Electric power to drive the electric motor in electric vehicles is provided by batteries, while fuel cell vehicles use power generated by hydrogen fuel cells. Interior noise while driving a vehicle seriously affects the driver's mood and is an important factor i...
