Abstract

The present invention relates to a power take-off apparatus using a transfer case of a four-wheel drive vehicle. An existing four-wheel drive vehicle has the problem that a power take-off is possible when the vehicle stops or travels on two-wheel drive, but not during four-wheel drive. In designing a transfer case of a four-wheel drive vehicle, two-wheel power transfer shaft and four-wheel power transfer shaft are connected through a chain to shift power of an engine from two-wheel drive to four-wheel drive, wherein the two-wheel power transfer shaft includes a main shaft (100) and a two-wheel drive connecting shaft (200) that are connected to enable power shift, and the four-wheel power transfer shaft includes an idle shaft (400) connected to the main shaft (100) and the chain (300), and a four-wheel drive connecting shaft (500) and a power take-off shaft (600) connected to both ends of the idle shaft (400). Therefore, the power take-off apparatus of the present invention enables power take-offs in a vehicle during four-wheel drive as well as two-wheel drive or parking, thereby enabling adoption of four-wheel drive to a special vehicle such as a snow-plow vehicle driving on snowy roads.

Description

4륜구동 차량의 트랜스퍼캐이스를 이용한 동력인출장치{outpevice using a transfer case of four-wheel drive automobile}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a four-wheel drive vehicle,

본 발명은 4륜구동 차량의 트랜스퍼캐이스를 이용한 동력인출장치에 관한 것으로서, 더욱 상세히는 4륜구동 차량에 탑재되는 트랜스퍼캐이스의 구조를 변경하여 정차중이거나 2륜 및 4륜으로 구동 시에도 동력을 손쉽게 인출할 수 있도록 하여 겨울철 눈길에서 높은 접지력을 필요로 하는 제설차량과 같은 특수차량에서 4륜구동을 가능하게 하여 제설 작업능률을 향상시킬 수 있도록 한 4륜구동 차량의 트랜스퍼캐이스를 이용한 동력인출장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power take-off device using a transfer case of a four-wheel drive vehicle, and more particularly to a power take-off device for a four- To a power take-off device using a transfer case of a four-wheel drive vehicle, which enables four-wheel drive in a special vehicle such as a snow removal vehicle that requires a high level of grounding force in winter snow roads, thereby improving the efficiency of snow removal work.

일반적으로 제설차량이나 청소차량과 같이 도로 주행에서의 작업뿐만 아니라 상습적으로 눈이 오는 특수한 상황 및 지역에서도 작업을 해야 하는 차량들은 전륜 또는 후륜만을 구동하면서 작업해야 하는 불리한 점이 있어 이러한 차량에의 4륜구동은 필수 선택사항일 것이다.Generally, there are disadvantages in that vehicles that need to work not only in road driving such as snow removal vehicles and clean vehicles but also in special situations and areas where snow habitually raises are required to operate while driving only front wheels or rear wheels. Therefore, Will be a required option.

4륜구동 차량은 전륜 또는 후륜만 구동하는 것이 아니라 4륜 모두 구동함으로써 4륜구동 주행 시에 전륜 및 후륜의 4륜에 구동력을 분산시킬 수 있으므로 낮은 마찰계수를 가지는 노면에 대해서도 우수한 주행성능을 발휘할 수 있다.The four-wheel drive vehicle is driven not by the front wheel or the rear wheel, but by driving all four wheels, the driving force can be distributed to the four wheels of the front wheel and the rear wheel during the four-wheel drive running, .

일반적인 후륜구동 차량에서의 4륜구동시스템은 전륜 및 후륜을 모두 구동하거나 후륜만 구동할 수 있도록 주행조건에 따라 자동으로 전환시킬 수 있는 트랜스퍼캐이스를 탑재하고 있다.A four-wheel drive system in a general rear-wheel-drive vehicle is equipped with a transfer case that can be automatically switched depending on driving conditions so that both the front and rear wheels can be driven or only the rear wheels can be driven.

즉, 도 1 은 트랜스퍼캐이스의 구조로서 이륜구동 시에는 메인축(10)을 통하여 후륜으로 동력이 전달되게 하고, 사륜구동 전환 시에는 메인축(10)과 연결된 체인(30)을 통하여 4륜구동축(50)을 통해 전륜으로 동력이 전달되게 하는 것이다.That is, FIG. 1 shows a structure of a transfer carrier in which power is transmitted to the rear wheels through the main shaft 10 during two-wheel drive and is transmitted through the chain 30 connected to the main shaft 10 during four- So that the power is transmitted to the front wheels through the front wheels 50.

한편, 제설차와 같이 눈길에서도 강한 접지력을 발휘해야 하는 차량은 주로 4륜 구동 차량인데 이러한 제설차 같은 경우는 차량을 구동시키는 동력 이외에 제설삽을 구동시키는 별도의 동력을 필요로 하기 때문에 변속기로 부터 동력을 인출하여 제설삽을 구동시켰다.On the other hand, vehicles such as snowmobiles, which are required to exert a strong grip on snow, are mainly four-wheel drive vehicles. In the case of such a snowmobile, in addition to the power for driving the vehicle, a separate power for driving the snowmobile shovel is required. And the snow shovel was driven.

그런데 종래에는 4륜구동 차량의 제설차에서 동력을 인출하는 경우는 차량이 정지하거나 2륜구동 시에만 동력을 인출할 수 있는 것이고, 4륜구동 시에는 동력을 인출하지 못하여 즉, 눈길에서 4륜구동으로 강력한 힘을 발휘하고자 차량을 4륜구동으로 운행할 경우에는 동력을 별도로 인출하지 못하기 때문에 제설삽을 구동시킬수 없어 부득이하게 차량이 정지된 상태이거나 2륜구동으로 운행을 하면서 제설삽을 구동시켜야 하므로 그만큼 작업능률이 떨어지는 문제점이 있었다.However, in the past, when power is taken out from a snow plow of a four-wheel drive vehicle, the power can be drawn out only when the vehicle is stopped or two-wheel drive. In the case of four-wheel drive, the power can not be drawn out. If the vehicle is driven by four-wheel drive for the purpose of exertion, the power can not be drawn out separately. Therefore, the snow shovel can not be driven. Inevitably, the vehicle must be stopped or the snow shovel must be driven while driving with two- There was a problem.

이처럼 종래에는 4륜구동 차량의 4륜구동 시에는 별도의 동력을 인출하지 못하기 때문에 눈길을 운행하여야 하는 제설차량에서 4륜구동을 채택하는데 어려움이 있었다.
Thus, conventionally, there is a difficulty in adopting four-wheel drive in a snow removal vehicle that requires snow driving because separate power can not be drawn at the time of four-wheel drive of a four-wheel drive vehicle.

이에 본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 4륜구동 차량에 사용되는 트랜스퍼캐이스의 구조를 변경하여 정차시나 2륜구동은 물론 4륜구동 시에도 동력을 원활히 인출할 수 있도록 한 4륜구동 차량의 트랜스퍼캐이스를 이용한 동력인출장치를 제공하기 위한 것이다.

이와 같은 본 발명은 엔진의 동력을 2륜과 4륜으로 전환시킬 수 있도록 2륜 동력전달축과 4륜 동력전달축이 체인으로 연결되는 사륜구동차량의 트랜스퍼캐이스를 구성함에 있어서, 상기 2륜 동력전달축은 동력전환이 되도록 연결된 메인축(100)과 2륜구동연결축(200)으로 구성한다.In the present invention, the two-wheel power transmission shaft and the four-wheel power transmission shaft are connected by a chain so as to convert the power of the engine into two-wheel and four- The transmission shaft is composed of a main shaft 100 and a two-wheel drive connection shaft 200 connected to each other so as to be power-driven.

그리고 상기 4륜동력전달축은 상기 메인축(100)과 체인(300)으로 연결되는 아이들축(400) 및 아이들축(400) 양단에 연결되는 4륜구동연결축(500))과 동력인출축(600)으로 구성하여 정차 시 및 2륜 또는 4륜 구동 시 동력인출축(600)을 통해 엔진의 동력을 원활히 인출할 수 있도록 한 것이다.The four-wheel power transmission shaft includes an idle shaft 400 connected to the main shaft 100 and a chain 300 and a four-wheel drive connection shaft 500 connected to both ends of the idle shaft 400. The power take- So that the power of the engine can be smoothly taken out through the power take-off shaft 600 when the vehicle is stationary or when two or four wheels are driven.

이러한 본 발명은 4륜구동 차량에서 차량을 2륜구동과 4륜구동으로 전환시키기 위해 별도의 트랜스퍼캐이스를 설치하는 것은 종래와 마찬가지이다.In the present invention, it is the same as in the prior art to install a separate transfer case to convert a vehicle into two-wheel drive and four-wheel drive in a four-wheel drive vehicle.

그러나 본 발명에서의 특징은 트런스퍼캐이스의 구조를 변경하여 4륜구동 차량에서 차량이 정차하거나 2륜구동 시는 물론 4륜구동 시에도 엔진의 동력을 손쉽게 인출할 수 있도록 하여 보조 동력이 필요한 제설차량과 같은 특수차량을 4륜구동 차량으로 채택할 수 있도록 하여 제설 작업능률을 향상시킬 수 있도록 한 것이다.However, the present invention is characterized in that the structure of the transverse vehicle is changed so that the power of the engine can be easily drawn out even when the vehicle is stopped or the two-wheel drive or four-wheel drive is performed in the four- The same specific vehicle can be adopted as a 4WD vehicle, thereby improving the efficiency of snow removal work.

즉, 본 발명은 엔진의 동력을 후륜에 전달하기 위한 2륜동력전달축을 메인축(100)과 2륜구동연결축(200)으로 구성 하였다.That is, in the present invention, the two-wheel power transmission shaft for transmitting the power of the engine to the rear wheels is composed of the main shaft 100 and the two-wheel drive connection shaft 200.

그리고 엔진의 동력을 전륜에 전달하기 위한 4륜동력전달축은 아이들축(400)과 아이들축(400)양단에 4륜구동연결축(500))과 동력인출축(600)을 각각 연결되게 하였다.The four-wheel power transmission shaft for transmitting the power of the engine to the front wheels is connected to the power take-off shaft 600 and the idle shaft 400 and the four-wheel drive connection shaft 500 at both ends of the idle shaft 400, respectively.

여기서 상기 아이들축(400)은 메인축(100)과 체인(300)으로 연결하여 메인축(100)의 구동에 의해 아이들축(400)이 구동되게 하였다.The idle shaft 400 is connected to the main shaft 100 and the chain 300 so that the idle shaft 400 is driven by driving the main shaft 100.

그리고 본 발명에서는 2륜동력전달축인 메인축(100)과 2륜구동연결축(200) 및 4륜동력전달축인 아이들축(400)과 4륜구동연결축(500), 동력인출축(600)은 축 끝단을 각각의 전환용 슬리브(710)(720)(730)와 스플라인으로 연결하여 필요에 따른 동력을 연결, 또는 차단되게 하였다.In the present invention, the main shaft 100, the two-wheel drive connection shaft 200, the idle shaft 400 and the four-wheel drive connection shaft 500, the power take-off shaft 600, Splines the ends of the shafts with the respective switching sleeves 710, 720, and 730 to connect or disconnect power as needed.

또한, 2륜구동연결축(200)에는 2륜구동전환용 포크(810)와 2륜구동용 축지지베어링(910)을 설치하고, 4륜구동연결축(500))에는 4륜구동전환용 포크(820)와 4륜구동용 축지지베어링(920)을 설치하며, 동력인출축(600)에는 동력인출용 포크(830)와 동력인출용 축지지베어링(930)을 설치하였다.The two-wheel drive switching fork 810 and the two-wheel drive shaft support bearing 910 are provided in the two-wheel drive connection shaft 200 and the four-wheel drive switching fork 820 and the four- A four-wheel drive shaft support bearing 920 is provided, and a power take-off fork 830 and a power take-off shaft support bearing 930 are provided on the power take-off shaft 600.

따라서 본 발명은 도 3 에서와 같이 차량이 정차한 상태에서 동력을 인출할 경우에는 즉, 차량이 정차한 상태에서는 2륜구동연결축(200)과 4륜구동연결축(500)은 각각의 포크(810)(820)에 의해 당겨지면서 2륜구동연결축(200)은 메인축(100)의 슬리브(710)에서 분리되고, 4륜구동연결축(500)은 아이들축(400)의 슬리브(720)에서 분리된 상태이다.3, the two-wheel-drive linkage shaft 200 and the four-wheel drive linkage shaft 500 are connected to the respective forks 810 and 810, respectively, when the vehicle is in a stopped state, The two-wheel drive coupling shaft 200 is separated from the sleeve 710 of the main shaft 100 while the four-wheel drive coupling shaft 500 is separated from the sleeve 720 of the idle shaft 400 Respectively.

이에 따라 정지 시 동력을 인출하면 동력인출축(600)만이 아이들축(400)의 슬리브(730)에 접속되면서 동력인출용 축지지베어링(930)에 의해 원활한 구동을 하는 것이므로 정차한 상태에서 동력을 인출하면 동력은 메인축(100)으로 전달되면서 2륜구동연결축(200)으로는 전달되지 않고 메인축(100)과 연결된 체인(300)을 통해 아이들축(400)으로 전달된다.Accordingly, when the power is released during stoppage, only the power take-off shaft 600 is connected to the sleeve 730 of the idle shaft 400 and smoothly driven by the power take-off shaft support bearing 930. Therefore, The power is transmitted to the idle shaft 400 through the chain 300 connected to the main shaft 100 without being transmitted to the two-wheel drive coupling shaft 200 while being transmitted to the main shaft 100. [

이처럼 아이들축(400)으로 전달된 동력은 상기에서 언급한 바와 같이 4륜구동연결축(500)이 아이들축(400)의 슬리브(720)에서 분리된 상태이기 때문에 4륜구동연결축(500)으로는 동력이 전달되지 않고 곧바로 아이들축(400)의 슬리브(730)에 접속된 동력인출축(600)으로만 전달되기 때문에 차량 정지시 동력을 인출할 수 있는 것이다.Since the power transmitted to the idle shaft 400 is in a state in which the four-wheel drive connection shaft 500 is separated from the sleeve 720 of the idle shaft 400 as described above, Since the power is not transmitted and is transmitted only to the power take-off shaft 600 connected to the sleeve 730 of the idle shaft 400, the power can be drawn out when the vehicle is stopped.

또한, 도 4에서와 같이 2륜구동 시 동력을 인출할 경우에는 즉, 2륜구동 시에는 메인축(100)의 슬리브(710)에 2륜구동연결축(200)이 접속되어 2륜구동용 축지지베어링(910)에 의해 원활한 구동을 하는 상태이고, 4륜구동연결축(500)은 포크(820)에 의해 당겨지면서 아이들축(400)의 슬리브(720)에서 분리된 상태이다.4, the two-wheel drive coupling shaft 200 is connected to the sleeve 710 of the main shaft 100 to drive the two-wheel drive shaft support bearing (not shown) when the two- And the four wheel drive connection shaft 500 is pulled by the fork 820 and is separated from the sleeve 720 of the idle shaft 400. [

따라서 동력을 인출하면 동력인출축(600)이 아이들축(400)의 슬리브(730)에 접속됨에 따라 메인축(100)을 통해 2륜구동연결축(200)으로 전달되는 동력 중 일부가 체인(300)을 통해 아이들축(400)으로 전달되는 것이고, 아이들축(400)으로 전달된 동력은 4륜구동연결축(500)으로는 전달되지 않고 동력인출축(600)으로만 전달되기 때문에 2륜구동 시 동력을 인출할 수 있는 것이다.The power take-off shaft 600 is connected to the sleeve 730 of the idle shaft 400 so that some of the power transmitted to the two-wheel drive connecting shaft 200 through the main shaft 100 is transmitted to the chain 300 Since the power transmitted to the idle shaft 400 is transmitted to the power take-off shaft 600 without being transmitted to the four-wheel drive connecting shaft 500, the power transmitted to the idle shaft 400 through the power- Can be withdrawn.

그리고 도 5 에서와 같이 4륜구동 시에는 2륜구동연결축(200)이 메인축(100)의 슬리브(710)에 접속되고, 4륜구동연결축(500)은 아이들축(400)의 슬리브(720)에 접속된 상태이므로 즉, 동력이 2륜구동연결축(200)과 4륜구동연결축(500)모두에 전달되는 상태이기 때문에 이때 동력을 인출하면 아이들축(400)의 슬리브(730)에 동력인출축(600)이 접속되면서 아이들축(400)을 통해 4륜구동연결축(500)으로 전달되는 동력중 일부가 동력인출축(600)으로도 전달되어 4륜구동 시에도 동력을 인출할 수 있는 것이다.5, the two-wheel-drive coupling shaft 200 is connected to the sleeve 710 of the main shaft 100 and the four-wheel drive coupling shaft 500 is connected to the sleeve 720 of the idle shaft 400 when the four- The driving force is transmitted to both the two-wheel drive connection shaft 200 and the four-wheel drive connection shaft 500. When the power is drawn at this time, the sleeve 730 of the idle shaft 400 is connected to the power take- Some of the power transmitted to the four-wheel drive connection shaft 500 through the idle shaft 400 is also transmitted to the power take-off shaft 600 so that the power can be drawn out even when the four-wheel drive shaft 600 is connected.

이와는 반대로 4륜구동 시 동력을 인출하여 사용하다가 동력 인출을 차단하면 아이들축(400)의 슬리브(730)에 접속된 동력인출축(600)이 포크(830)에 의해 당겨져 분리됨에 따라 동력인출축(600)으로 전달된 동력은 차단되는 것이다.The power take-off shaft 600 connected to the sleeve 730 of the idle shaft 400 is pulled and separated by the fork 830, so that the power take- 600 are blocked.

상술 한 바와 같이 본 발명은 비록 한정된 실시 예에 의해 설명되었으나 본 발명은 이것에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허 등록청구범위의 균등범위 내에서 다양한 수정 및 변경이 가능하다 할 것이다
