무단 변속장치Continuously variable transmission

본 발명은 엔진의 구동력이 차량의 주행상태에 따라 무단으로 변속이 이루어지도록 하기 위한 변속장치에 관한 것이다.The present invention relates to a transmission for allowing the driving force of the engine to be continuously shifted according to the driving state of the vehicle.

일반적으로 차량의 변속장치는 엔진의 구동력을 구동륜에 전달하는 기능을 갖고 있는데, 이러한 변속장치에는 운전자의 의지대로 운전자가 직접 변속단을 선택하는 수동 변속장치와, 차량의 주행조건에 따라 자동적으로 변속이 이루어지는 자동 변속장치와, 각 변속단 사이에 특정한 변속 영역이 없이 무단으로 연속적인 변속이 이루어지는 무단 변속장치로 대별된다.In general, the transmission of the vehicle has a function of transmitting the driving force of the engine to the drive wheels. Such a transmission includes a manual transmission in which the driver directly selects a shift stage at the driver's will, and automatically shifts according to the driving conditions of the vehicle. These automatic transmissions are divided into a continuously variable transmission in which continuously continuous shifts are made without a specific speed change region between the respective shift stages.

상기와 같은 변속장치에 있어서, 본 발명은 유압을 이용하는 자동변속장치의 단점을 보완하여 연비 및 동력 전달성능, 그리고 중량면에서 큰 장점을 갖는 무단 변속장치에 관계하며, 이의 무단 변속장치는 입력축과 출력축에 장착되는 풀리의 직경 변위를 이용하는 방식이 주로 사용되고 있다.In the above-described transmission device, the present invention relates to a continuously variable transmission having great advantages in terms of fuel economy, power transmission performance, and weight by supplementing the disadvantages of the automatic transmission using hydraulic pressure, and the continuously variable transmission thereof has an input shaft. The method using the diameter displacement of the pulley mounted on the output shaft is mainly used.

상기 유성기어장치로 이용되는 전,후진 제어수단은, 전진 구동시에 구동축이 구동풀리와 직결로 이루어져 1:1로 동력을 전달하는 구조로 이루어진다.The forward and backward control means used as the planetary gear device has a structure in which the drive shaft is directly connected to the driving pulley at the time of forward driving to transmit power 1: 1.

또한 이렇게 변환된 구동력을 구동바퀴에 전달하기 위하여 종감속장치가 연결된다.In addition, the longitudinal reduction gear is connected to transfer the converted driving force to the driving wheel.

상기한 종감속장치는 별도로 형성되는 축에 기어비를 적절하게 조절함으로서 변속되는 동력을 주행상태에 적합하도록 구동바퀴에 전달하게 된다.The longitudinal reduction gear is configured to properly transmit a gear ratio to a separately formed shaft, thereby transmitting power to a driving wheel to be adapted to a driving state.

상기한 종래의 무단 변속장치는 작동상에는 별문제가 없으며 엔진의 구동력을 주행상태에 따라 무단 변속이 이루어지도록 함으로써 동력 효율을 증대시키고 있다.The conventional continuously variable transmission has no problem in operation and increases the power efficiency by allowing the continuously variable transmission to be made according to the driving state of the engine.

그러나 이러한 무단 변속장치는, 보다 컴팩트하게 제작되어야 코스트 및 중량을 절감시킬 수 있게되는 데 이에 충분히 만족하지 못하는 문제점이 있다.However, such a continuously variable transmission can be reduced in cost and weight only by making it more compact.

본 발명은 이러한 종래기술의 문제점을 해결하기 위하여 안출된 것으로써, 본 발명의 목적은 무단 변속 차량에 있어서 컴팩트하게 제작함으로서 코스트 및 중량을 감소시키는 무단 변속장치를 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a continuously variable transmission that reduces cost and weight by making a compact in a continuously variable transmission vehicle.
