Description

차량용 다단 변속기{MULTY-STAGE TRANSMISSION FOR VEHICLE}[0001] MULTI-STAGE TRANSMISSION FOR VEHICLE [0002]

본 발명은 차량용 다단 변속기에 관한 것으로서, 보다 상세하게는 가급적 적은 부품수와 간단한 구성으로 가급적 많은 변속단을 구현하여 차량의 연비를 향상시킬 수 있도록 하는 기술에 관한 것이다.BACKGROUND OF THE INVENTION 1.

In the case of engines, efforts are being made to reduce weight and improve fuel efficiency through technologies such as downsizing.

한편, 차량에 탑재되는 변속기에서 추구할 수 있는 연비 개선 방법 중에는 변속기의 다단화를 통해 엔진이 보다 효율적인 운전점에서 운전될 수 있도록 함으로써, 궁극적으로 연비를 향상시킬 수 있도록 하는 방법이 있다.On the other hand, among the fuel economy improvement methods that can be pursued in a vehicle-mounted transmission, there is a method for improving the fuel economy by allowing the engine to operate at a more efficient operating point through the multi-shoe of the transmission.

그러나, 변속기의 변속단이 증가하면 할수록 변속기를 구성하고 있는 내부 부품수도 증가하게 되어 탑재성, 원가, 중량, 전달 효율이 오히려 악화 될 수 있기 때문에, 변속기의 다단화를 통한 연비 개선 효과를 극대화시키기 위해서는 적은 부품수와 비교적 간단한 구성으로 최대한의 효율을 이끌어 낼 수 있는 변속기 구조를 고안하는 것이 중요하다고 할 수 있다.However, as the transmission gear ratio of the transmission increases, the number of internal components constituting the transmission increases, so that the mountability, cost, weight, and transmission efficiency may be deteriorated. Therefore, maximization of fuel efficiency improvement through multi- It is important to devise a transmission structure that can achieve maximum efficiency with a small number of components and a relatively simple configuration.

Will be.
