본 발명은 차량용 무단 변속장치에 관한 것으로서, 보다 상세하게는 구성을 간단히 하여 제조원가를 절감하고, 종치 후륜 구동 차량에 용이하게 적용할 수 있도록 한 차량용 무단 변속장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a continuously variable transmission for a vehicle, and more particularly, to a continuously variable transmission for a vehicle which simplifies the construction to reduce the manufacturing cost and can be easily applied to a rear-

차량의 변속장치는 엔진의 구동력을 구동륜에 전달하는 기능을 갖고 있는데, 이러한 변속장치에는 운전자의 의지대로 직접 변속단을 선택하는 수동 변속장치와, 차량의 주행 조건에 따라 자동적으로 변속이 이루어지는 자동 변속장치와, 각 변속단 사이에 특정한 변속 영역이 없이 무단으로 연속적인 변속이 이루어지는 무단 변속장치로 대별된다.The transmission of the vehicle has a function of transmitting the driving force of the engine to the drive wheels. The transmission includes a manual transmission device for directly selecting a transmission according to the driver's preference, an automatic transmission for automatically shifting in accordance with the driving conditions of the vehicle And a step-variable shifting device in which continuously variable shifting is performed without any specific shifting region between each gear range.

상기와 같은 변속장치에 있어서, 본 발명은 유압을 이용하는 자동변속장치의 단점을 보완하여 연비 및 동력 전달성능, 그리고 중량면에서 큰 장점을 갖는 무단 변속장치에 관계한다.BACKGROUND OF THE INVENTION 1.

또한, 모든 회전동력의 하중이 하나의 벨트에 의하여 전달됨으로써, 이에 따른 벨트의 수명이 단축됨은 물론 내구성을 크게 기대할 수 없다는 문제점을 내포하고 있다.In addition, since the load of all the rotational power is transmitted by one belt, the lifetime of the belt is shortened, and the durability can not be expected.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 보다 구성이 간단하면서도 무단 변속 영역의 폭을 크게 할 수 있도록 하여 엔진의 동력을 효과적으로 이용할 수 있도록 하고, 종치 후륜 구동 차량에 용이하게 적용할 수 있는 차량용 무단 변속장치를 제공함에 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a continuously variable transmission capable of effectively using the power of the engine, The present invention provides a vehicle continuously variable transmission that can be easily applied to a vehicle.

또한, 상기 엔진의 동력을 효과적으로 이용함으로써, 동력성능을 향상시키고, 벨트가 분담하는 하중을 양분시켜 분담토록 함으로써, 내구성을 향상시킬 수 있는 차량용 무단 변속장치를 제공함에 있다.It is another object of the present invention to provide a vehicular stepless transmission capable of improving power performance by effectively utilizing the power of the engine and improving durability by dividing the load shared by the belts into two.

이하, 상기의 목적을 구체적으로 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 의한 제1 실시예의 구성도로서, 이는 발진수단(2)으로 토오크 컨버터(4)를 적용한 예를 도시한 것이다.FIG. 1 is a configuration diagram of a first embodiment according to the present invention, which shows an example in which the torque converter 4 is applied to the oscillation means 2.

상기 토오크 컨버터(4)는 엔진(6)의 크랭크축에 직결되어 회전하는 펌프 임펠러(8)와; 이 펌프 임펠러(8)와 대향 배치되어 분출되는 오일에 의하여 함께 회전하는 터어빈 런너(10)와; 이들 펌프 임펠러(8)와 터어빈 런너(10) 사이에 배치되어 오일의 흐름을 바꾸어 주어 펌프 임펠러(8)의 회전력을 증가시켜 주는 스테이터(12)를 포함하여 이루어진다.The torque converter (4) includes a pump impeller (8) rotating directly on the crankshaft of the engine (6); A turbine runner 10 disposed opposite to the pump impeller 8 and rotated together by the oil to be jetted; And a stator 12 disposed between the pump impeller 8 and the turbine runner 10 to change the flow of the oil to increase the rotational force of the pump impeller 8.

이에 따라 엔진이 회전을 하면 상기 토오크 컨버터(4)내에 충진된 오일이 펌프 임펠러(8)에서 분출되어 터어빈 런너(10)로 공급되면서 터어빈 런너(10)를 구동시킨 다음 스테이터(12)로 유입된다.Accordingly, when the engine rotates, the oil filled in the torque converter 4 is ejected from the pump impeller 8 and supplied to the turbine runner 10 to drive the turbine runner 10, and then flows into the stator 12 .

또한, 상기 스테이터(12)로 유입된 오일은 그 방향을 바꾸어 다시 펌프 임펠러(8)로 유입되는 작용을 반복하게 되는데, 이때 스테이터(12)의 회전에 의하여 스테이터(12)가 분담하는 터어빈 런너(10)의 회전력과 펌프의 회전력과의 사이에 차이가 생겨 토오크 변환이 이루어지게 되는 것이다.The oil introduced into the stator 12 changes its direction and then flows into the pump impeller 8 repeatedly. At this time, the turbine runner (stator) 12, which is shared by the stator 12 by the rotation of the stator 12 10 and the rotational force of the pump, so that the torque conversion is performed.

그리고 상기 토오크 컨버터(4)의 후측으로 배치되는 동력 단속기구(14)는 토오크 컨버터(4)로부터 출력되는 회전동력이 후진 변속부로 전달되는 것을 선택적으로 단속하는 것으로서, 통상의 다판 클러치가 사용된다.The power interrupter 14 disposed at the rear side of the torque converter 4 selectively interrupts the rotational power output from the torque converter 4 to be transmitted to the reverse speed change section, and a conventional multi-plate clutch is used.

상기에서 다판 클러치의 구성을 공지이므로 상세한 설명은 생략하며, 이의 작동원인 유압은 엔진의 구동력에 의한 오일펌프(미도시)에 의하여 발생된다.Since the configuration of the multi-plate clutch is known in the above, a detailed description thereof will be omitted, and the hydraulic pressure for the operation thereof is generated by an oil pump (not shown) by the driving force of the engine.

상기 발진수단(2)을 통해 출력되는 회전동력은 제1 축(16)과 제2 축(18)상에 배치되는 전,후진 제어수단(20)에 의하여 운전자의 의지에 따라 차량의 전,후진을 제어된다.The rotational power output through the oscillating means 2 is transmitted to the front and rear of the vehicle by the forward and backward control means 20 disposed on the first shaft 16 and the second shaft 18, .

이의 전,후진 제어수단(20)은 제1 축(16)에 연동되는 클러치 허브(22)를 포함하는 슬리이브(24)의 좌우측으로 전,후진용 클리치 기어(26)(28)가 배치되고, 이의 전, 후진용 클리치 기어(26)(28)들은 각각 전,후진 입력기어(30)(32)와 일체로 형성되는 동기장치로 이루어진다.The forward and backward control means 20 includes front and rear reverse gears 26 and 28 disposed on the right and left sides of the sleeve 24 including the clutch hub 22 interlocked with the first shaft 16 And the front and rear reverse gears 26 and 28 are composed of a synchronizing device integrally formed with the forward and reverse input gears 30 and 32, respectively.

이에 따라 슬리이브(24)가 전진용 클러치 기어(26)와 치합되면 전진 입력기어(30)를 구동시키게 되고, 후진용 클러치 기어(28)와 치합되면 후진 입력기어(32)를 구동시키게 되는 것이다.Thus, when the sleeve 24 meshes with the forward clutch gear 26, the forward input gear 30 is driven. When the sleeve gear 24 meshes with the reverse clutch gear 28, the reverse input gear 32 is driven .

그리고 상기 전,후진 입력기어(30)(32)는 제2 축(18)에 형성되어 있는 전,후진 기어(34)(36)와 치합되는데, 후진 입력기어(32)와 후진기어(36) 사이에는 아이들링 기어(38)가 개개되는 구성을 갖는다.The forward and backward input gears 30 and 32 engage with the forward and reverse gears 34 and 36 formed on the second shaft 18. The forward input gear 32 and the reverse gear 36, And an idling gear 38 is disposed between the two gears.

따라서, 제1 축(16)의 회전동력은 슬리이브(24)의 물림 위치에 따라 동일 또는 반대방향으로 제2 축(18)을 구동시키게 되는 것이다.Accordingly, the rotational power of the first shaft 16 drives the second shaft 18 in the same or opposite direction according to the engaging position of the sleeve 24. [

상기와 같이, 전,후진 제어수단(20)에 의하여 그 회전 방향이 동일하거나 또는 전환되어 제2 축(18)으로 입력된 동력은 제1 무단 변속수단(40)를 통해 무단 변속이 이루어지게 된다.As described above, the power that is inputted to the second shaft 18 by the forward / reverse control means 20 whose rotational direction is the same or is changed, is subjected to the continuously-variable shifting through the first continuously-variable transmission means 40 .

즉, 제1 무단 변속수단(40)은 제2 축(18)의 후단부와, 이 제2 축(18)의 하측에 소정의 간격을 두고 평행하게 배치되는 제3 축(42)상에 배치되어 직경이 유압에 의하여 가변되는 구동 및 종동풀리(44)(46)와, 상기 풀리를 상호 연결하여 주는 벨트(48)를 포함하여 이루어진다.Namely, the first stepless change-speed transmission mechanism 40 is disposed on the third shaft 42 disposed parallel to the rear end of the second shaft 18 at a predetermined interval below the second shaft 18 A drive and driven pulley (44) (46) whose diameter is varied by hydraulic pressure, and a belt (48) for interconnecting the pulleys.

상기에서 구동 및 종동풀리(44)(46)는 직경의 변화에 의하여 무단 변속이 이루어지도록 하는 것으로서, 제2도는 그것을 가능하게 하는 일 실시예의 구성을 보여주고 있다.In the above, the drive and driven pulleys 44 and 46 cause the continuously variable shifting to be performed by a change in diameter, and the second and third embodiments show the construction of the embodiment.

상기 구동풀리(44)는 고정측 쉬이브(50)와 가변측 쉬이브(52)로 이루어지는데, 고정측 쉬이브(50)는 제2 축(18)과 일체로 형성되어 있으며, 가변측 쉬이브(52)는 이 제2 축(18)상에서 좌우 이동할 수 있는 상태로 결합되고 있다.The drive pulley 44 is composed of a fixed side sheave 50 and a variable side sheave 52. The fixed side sheave 50 is formed integrally with the second shaft 18, Eve 52 is coupled on the second shaft 18 so as to be movable left and right.

상기 가변측 쉬이브(52)측에는 케이싱 부재(54)가 설치되어 이들 사이에 유압 쳄버(56)를 형성하고 있으며, 이 유압 쳄버(56)는 제2 축(18)에 형성된 유로(58)를 통하여 엔진의 구동력에 의해 생성되는 압력 유체가 공급될 수 있도록 되어 있다.A casing member 54 is provided on the side of the variable side sheave 52 and forms a hydraulic chamber 56 therebetween. The hydraulic chamber 56 has a passage 58 formed in the second shaft 18 So that the pressure fluid generated by the driving force of the engine can be supplied.

그리고 종동풀리(46)는 상기와 마찬가지로 고정측 쉬이브(60)와 가변측 쉬이브(62)로 이루어지되, 상기 고정측 쉬이브(60)가 제3 축(42)과 일체로 형성되고, 가변측 쉬이브(62)는 상기 제3 축(42)상에서 좌우 이동할 수 있도록 결합된다.Side sieve 60 and the variable-side sheave 62. The fixed-side sheave 60 is integrally formed with the third shaft 42, and the fixed- The variable-side sheave 62 is coupled to the third shaft 42 so as to be movable left and right.

또한, 이의 가변측 쉬이브(62)에는 케이싱 부재(64)가 개재되어 유압 쳄버(66)를 형성하고 있으며, 상기 유압 쳄버(66)에는 제3 축(42)에 형성된 유로(68)를 통하여 엔진의 구동력에 의해 생성되는 압력 유체가 공급될 수 있도록 되어 있다.The variable side sheave 62 has a casing member 64 interposed therebetween to form a hydraulic chamber 66. The hydraulic chamber 66 is provided with a flow path 68 formed on the third shaft 42 So that the pressure fluid generated by the driving force of the engine can be supplied.

따라서 제2 축(18)을 통해 회전동력이 제1 무단 변속수단(40)으로 전달되면, 무단 변속이 이루어지면서 제3 축(42)을 구동하게 되는데, 이때 구동풀리(44)와 종동풀리(46)의 외경 변화에 따라 변속이 이루어지게 된다.When the rotational power is transmitted to the first continuously variable transmission 40 through the second shaft 18, the third shaft 42 is driven while the continuously-variable transmission is performed. At this time, the drive pulley 44 and the driven pulley 46 are shifted in accordance with the outer diameter change.

그의 회전속도 변화 조건은, 첫째, 구동풀리(44)와 종동풀리(46)의 외경이 동일할 때와, 둘째 구동풀리(44)의 외경이 종동풀리(46)의 직경 보다 큰 경우와, 셋째 구동풀리(44)의 직경이 종동풀리(46)의 직경보다 작은 경우로 나누어 생각할 수 있다.The rotational speed changing conditions are as follows: first, when the outer diameters of the drive pulley 44 and the driven pulley 46 are the same, when the outer diameter of the second drive pulley 44 is larger than the diameter of the driven pulley 46, And the case where the diameter of the drive pulley 44 is smaller than the diameter of the driven pulley 46 can be considered.

첫째 조건으로 구동 및 종동풀리(44)(46)의 외경이 동일한 경우에는 1 : 1의 변속비를 갖게 된다.Under the first condition, when the outer diameters of the drive and driven pulleys 44 and 46 are the same, the transmission ratio is 1: 1.

그리고 둘째로 구동풀리(44)의 외경이 종동풀리(46)의 직경 보다 큰 경우에는 구동풀리(44)의 회전수 보다 종동풀리(46)의 회전수가 커지기 때문에 증속이 이루어지게 되며, 셋째 구동풀리(44)의 외경이 종동풀리(46)의 직경보다 작아지는 경우에는 구동풀리(44)의 회전수가 종동풀리(46)의 회전수 보다 작아지기 때문에 감속이 이루어지게 되는 것이다.Secondly, when the outer diameter of the drive pulley 44 is larger than the diameter of the driven pulley 46, the rotation speed of the driven pulley 46 becomes larger than the rotation number of the drive pulley 44, When the outer diameter of the driven pulley 44 is smaller than the diameter of the driven pulley 46, the number of revolutions of the drive pulley 44 becomes smaller than the number of revolutions of the driven pulley 46, so that the deceleration is performed.

이러한 작용으로 주행 레인지에서는 출발 시점부터 고속 주행까지 변속단 구분이 없는 점진적인 변속이 이루어지게 되는 것이다.With this operation, the shift range is gradually shifted from the starting point to the high-speed travel without the shift stage.

상기와 같이 1차로 무단 변속이 이루어진 회전동력은 다시 제2 무단 변속수단(60)에 의하여 2차 무단 변속이 이루어지게 된다.The second-mentioned continuously-variable shifting means 60 causes the second-mentioned continuously-variable shifting to be performed again by the rotational power having been subjected to the continuously-variable shifting as described above.

상기 제2 무단 변속수단(70)은 제1 무단 변속수단(40)과 마찬가지로 구동축인 제3 축(42)의 후측에 배치된 구동풀리(72)와, 제3 축(42)의 상부 후측으로 배치되는 제4 축(74)상에 배치되는 종동풀리(76)와, 이들을 상호 연결하는 벨트(78)를 포함하여 이루어진다.The second continuously variable transmission mechanism 70 includes the drive pulley 72 disposed on the rear side of the third shaft 42 as the drive shaft and the drive pulley 72 disposed on the rear side of the upper side of the third shaft 42, A driven pulley 76 disposed on a fourth shaft 74 to be disposed, and a belt 78 interconnecting them.

상기에서 제2 무단 변속수단(70)을 형성하는 구동 및 종동폴리(72)(76)의 구성과 그 작동은 제1 무단 변속수단(40)과 동일하므로 상세한 설명은 생략한다.The configuration and operation of the drive and driven pulleys 72 and 76 for forming the second stepless transmission 70 are the same as those of the first stepless change-speed transmission 40, and thus the detailed description thereof will be omitted.

그리고 상기 제2 무단 변속수단(70)으로부터 동력은 전달받은 제4 축(74)은 이에 기어 전동되는 출력축(76)을 통해 미도시한 후륜 종감속장치를 통해 구동륜인 후륜을 구동시키게 되는 것이다.The fourth shaft 74, which receives the power from the second stepless speed change unit 70, drives the rear wheel, which is a driving wheel, via a rear wheel longitudinal reduction unit not shown through an output shaft 76 that is driven by the fourth shaft 74.

이와 같이 본 발명의 제1 실시예에 의하면 전,후진 제어수단(20)으로부터 회전 방향이 결정된 회전동력은 제1, 2 무단 변속수단(40)(70)을 통해 2차로 무단 변속이 이루어져 그 변속폭이 매우 커진다.As described above, according to the first embodiment of the present invention, the rotational power determined by the forward / reverse control means 20 is subjected to the second-order continuously-variable shifting through the first and second continuously-variable shifting means 40 and 70, The width is very large.

이에 따라 엔진의 출력을 보다 효과적으로 이용할 수 있음은 물론 동력성능을 크게 향상시킬 수 있게 된다.Accordingly, the output of the engine can be used more effectively, and the power performance can be greatly improved.

그리고 회전 하중이 2개의 벨트로 양분됨으로써, 무단 변속수단의 내구성을 향상시킬 수 있게 되는 것이다.Further, since the rotational load is divided by the two belts, the durability of the continuously-variable shifting means can be improved.

제3도는 본 발명에 의한 제2 실시예를 도시한 것으로서, 이는 상기 제1 실시예에 있어서, 전,후진 제어수단(20)을 형성하는 동기장치를 제2 축(18)상에 배치한 것이다.3 shows a second embodiment according to the present invention in that in the first embodiment the synchronizing device for forming the forward and backward control means 20 is arranged on the second shaft 18 .

This is because in the first embodiment, the forward and backward control means 20 is arranged on the second shaft 18 and the third shaft 42 The synchronizing device is arranged on the second shaft and the forward and reverse gears 34 and 36 are disposed on the third shaft 42 and the starting control mechanism 14 is disposed on the second shaft 18 will be.

상기와 같은 제2, 3, 4 실시예의 작동은 제1 실시예와 동일하므로 상세한 설명은 생략한다.Since the operation of the second, third, and fourth embodiments is the same as that of the first embodiment, a detailed description thereof will be omitted.

제6도 내지 제9도는 본 발명에 의한 제5 내지 제8 실시예를 도시한 것으로서, 이는 상기 제1 내지 제4 실시예에 있어서, 이들 실시예의 발진수단(2)에 적용되는 토오크 컨버터(4) 대신에 토셔널 댐퍼(80)을 적용한 것으로서, 그 작용은 상기한 실시예와 동일하므로 상세한 설명은 생략한다.6 to 9 show fifth to eighth embodiments according to the present invention.
