The wet disk 62a of 62 is brought into close contact with the spring force of the return spring 70 so that power is transmitted to the double speed turn shaft 54 to drive the double speed turn shaft 54.

그리고, 증속시의 동력전달과정을 살펴보면,And, if you look at the power transmission process during the increase,

엔진으로 부터 동력을 전달받는 주행계구동축(51)에 구비되는 전륜구동기어(50)와 아이들기어(52)를 통하여 아이들샤프트(53)의 전측에 구비되는 대기어(56)로 동력이 전달되어 아이들샤프트(53)가 구동한다.Power is transmitted to the standby gear 56 provided on the front side of the idle shaft 53 through the front wheel drive gear 50 and the idle gear 52 provided in the traveling system drive shaft 51 that receives power from the engine. The idle shaft 53 is driven.

By helping to return to the initial (non-accelerated state).

상기와 같이 본 발명에서는 배속턴샤프트(54)에 구비되는 클러치어셈블리(60)를 듀얼타입으로 하여 전륜 증속시 마찰을 최소화 하여 소음을 저감시킬 수 있는 것은 물론, 마모 및 손상으로 발생할 수 있는 이물질에 의하여 오일이 오염되는 것을 방지하여 클러치어셈블리(60)의 작동성과 내구성을 향상시킬 수 있는 등의 장점을 가진다.As described above, in the present invention, the clutch assembly 60 provided in the double speed turn shaft 54 is a dual type, which minimizes the friction during the increase of the front wheel, thereby reducing the noise, as well as debris that may occur due to wear and damage. By preventing the oil from being contaminated by the clutch assembly 60 has the advantage of improving the operability and durability of the clutch assembly (60).

이상과 같은 본 발명은 주행계구동축으로 부터 동력을 전달받는 배속턴샤프트에 구비되는 클러치를 듀얼타입으로 구성하여 전륜의 증속과 비증속 선택을 위한 작동성을 향상시켜 클러치 작동에 따르는 소음발생을 저감시키고 금속충돌로 야기되는 마모 및 손상으로 인한 작동오일의 오염을 방지하여 작동성과 품질이 향상된 클러치를 제공하고 사용자들의 편익향상에 기여할 수 있는 등 다양한 효과를 얻을 수 있다.The present invention as described above comprises a dual type of the clutch provided in the double speed turn shaft that receives power from the driving system drive shaft to improve the operability for the increase and non-speed selection of the front wheel to reduce the noise generated by the clutch operation It is possible to achieve various effects such as providing a clutch with improved operability and quality by contributing to the improvement of operation and quality by preventing contamination of the working oil due to wear and damage caused by metal collision.

또한 비증속클러치는 스프링 가압식이기 때문에 유압에 의한 출력 손실이 적으며, 유압밸브는 ON/OFF형으로 가격이 저렴하여 전체적인 생산비용을 절감할 수 있는 등의 효과를 부수적으로 얻을 수 있다.In addition, since the non-acceleration clutch is spring-loaded, there is little output loss due to hydraulic pressure, and the hydraulic valve is ON / OFF type, which is inexpensive and can reduce the overall production cost.
