Description

전기자동차의 감속기 연결구조 {Connecting Structure of Reduction Gear for electric vehicle}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vehicle,

본 발명은 전기자동차의 감속기 연결구조에 관한 것이다.
The present invention relates to a reduction gear connection structure of an electric vehicle.

일반적으로 전기자동차의 동력 전달은 배터리 전원에 의하여 구동 모터가 구동되면, 그 구동력은 감속기로 전달되고, 감속기에서 감속된 구동력은 디프렌셜 장치 및 출력축을 통하여 양측 구동륜으로 전달된다.Generally, when the driving motor is driven by the battery power, the driving force is transmitted to the reduction gear, and the driving force decelerated by the reduction gear is transmitted to both the driving wheels through the differential gear and the output shaft.

상술한 바와 같은 종래의 전기자동차의 감속기 연결구조에 의하면, 구동 모터에서 발생한 구동력이 모터축의 외부에 연결된 인풋기어를 통해서 동력을 전달한다. According to the conventional decelerator connecting structure of the electric vehicle, the driving force generated by the driving motor transmits power through the input gear connected to the outside of the motor shaft.

이때, 모터와 감속기가 일체로 조립되어 인풋기어를 통한 동력전달시 발생하는 반발력은 모터축 베어링이 지지하게 되는데, 감속기의 기어로부터 전달되는 반발력이 크므로 일반적인 모터의 베어링 대비 고용량의 베어링이 요구되며, 베어링의 내구성에 문제가 발생할 확률이 높다.
At this time, since the motor shaft bearing is supported by the repulsive force generated when the motor and the speed reducer are integrally assembled and the power transmitted through the input gear is transmitted, since the repulsive force transmitted from the gear of the speed reducer is large, , There is a high probability of causing a problem in the durability of the bearing.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 감속기의 반발력을 지지할 수 있는 전기자동차의 감속기 연결구조를 제공하는데 그 목적이 있다.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a reduction gear connection structure of an electric vehicle capable of supporting a repulsive force of a speed reducer.

상기한 목적을 달성하기 위해 본 발명의 일 측면에 따른 전기자동차의 감속기 연결구조는,According to an aspect of the present invention, there is provided a reduction gear connection structure for an electric vehicle,

상기 인풋하우징의 내부에는 상기 인풋하우징의 일측과 대응하는 내부 커버가 설치되어 상기 인풋하우징과 함께 상기 인풋기어를 지지하는 한 쌍의 인풋 베어링이 설치되는 것을 특징으로 한다.The input housing is provided with an inner cover corresponding to one side of the input housing, and a pair of input bearings for supporting the input gear together with the input housing are installed.

상기 내부 커버의 일측은 상기 인풋하우징의 타측에 지지되고, 그 타측은 상기 인풋기어와 일정거리 이격되어 사이에 어느 하나의 인풋 베어링이 설치되는 것을 특징으로 한다.One side of the inner cover is supported on the other side of the input housing, and the other side of the inner cover is spaced apart from the input gear by a certain distance.

상기 인풋하우징의 일측 역시 상기 인풋기어와 일정거리 이격되어 사이에 다른 하나의 인풋 베어링이 설치되는 것을 특징으로 한다.
The other end of the input housing is spaced a predetermined distance from the input gear and another input bearing is provided between the input housing and the input gear.

전술한 바와 같이 본 발명에 따른 전기자동차의 감속기 연결구조에 의하면, 모터와 감속기를 분리하여 모터축 베어링은 구동 모터의 회전에 의한 구름 저항만을 지지하며, 감속기 내부에 기어의 반발력을 지지할 수 있는 별도의 인풋 베어링이 설치되므로 모터축 베어링의 내구성을 향상시킬 수 있다.
As described above, according to the decelerator connecting structure of the electric vehicle according to the present invention, since the motor and the reducer are separated from each other, the motor shaft bearing supports only the rolling resistance due to the rotation of the driving motor, Since a separate input bearing is installed, the durability of the motor shaft bearing can be improved.

An input gear 230 engaged with the motor shaft 130, a reduction gear 240 connected to the input gear 230 to reduce driving force of the motor shaft 130, and a reduction gear housing 220 of the input gear 230. A differential device 250 including a deep gear 251 and a deep housing 252 therein, and a transmission shaft 260 connecting the deep gear 241 and the reduction gear 240. Here, the differential device 250 is a known construction for transmitting the driving force to the both-side drive wheels through the output shaft 253, and a detailed description thereof will be omitted.

특히, 상기 인풋하우징(210)의 내부에는 상기 인풋하우징(210)의 일측(211)과 대응하는 내부 커버(270)가 설치되어 상기 인풋하우징(210)과 함께 상기 인풋기어(230)를 지지하는 한 쌍의 인풋 베어링(280)이 더 설치된다.

이하, 도면을 참조하여 상술한 본 발명 전기자동차의 감속기 연결구조의 작용에 대해 살펴본다.Hereinafter, the operation of the reduction gear connection structure of the electric vehicle of the present invention described above with reference to the drawings will be described.

베터리의 전원이 인가되면 구동 모터(100)의 회전자(110)에서 발생한 회전력이 모터축(130)에 조립된 인풋기어(230)를 통해서 동력이 전달된다.The power generated by the rotor 110 of the driving motor 100 is transmitted through the input gear 230 assembled to the motor shaft 130 when the power of the battery is applied.

상술한 바와 같은 본 발명의 전기자동차의 감속기 연결구조에 의하면, 모터와 감속기를 분리하여 모터축 베어링은 구동 모터의 회전에 의한 구름 저항만을 지지하며, 감속기 내부에 기어의 반발력을 지지할 수 있는 별도의 인풋 베어링이 설치되므로 모터축 베어링의 내구성을 향상시킬 수 있다.According to the decelerator connecting structure of the electric vehicle of the present invention as described above, since the motor shaft and the speed reducer are separated from each other, the motor shaft bearing supports only the rolling resistance due to the rotation of the driving motor, Since the input bearing of the motor shaft bearing is installed, the durability of the motor shaft bearing can be improved.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나 이에 한정되지 않으며, 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형 가능함은 물론이다.While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It is to be understood that various changes and modifications may be made without departing from the scope of the present invention.
