Description

오작동 방지 기능을 갖춘 듀얼클러치변속기{Gear actuator device for dual clutch transmission} Gear actuator for dual clutch transmission

본 발명은 듀얼클러치변속기에 관한 것으로, 특히 변속시 셀렉트(Slect) 오작동을 방지할 수 있는 듀얼클러치변속기에 관한 것이다.The present invention relates to a dual clutch transmission, and more particularly, to a dual clutch transmission capable of preventing a select malfunction during shifting.

일반적으로 듀얼클러치변속기는 자동변속기처럼 운전이 편리할 뿐만 아니라, 단판클러치를 적용한 수동변속기 차량보다도 더 높은 연비효율을 얻을 수 있다. In general, the dual clutch transmission is not only convenient to operate as an automatic transmission, but also achieves higher fuel efficiency than a manual transmission vehicle employing a single clutch.

상기와 같은 듀얼클러치변속기는 1개의 클러치로 1,3,5단 변속기어를 단속하고, 또 다른 1개의 클러치로는 2,4,6단 변속기어를 단속하는 작용을 함으로써, 2개의 기어가 동시에 물릴수 있는 작동상태를 갖는 특징이 있다.The dual clutch transmission as described above controls the 1st, 3rd and 5th gears with one clutch and the 2nd, 4th and 6th gears with the other clutch. It is characterized by a biteable operating state.

일례로, 현재 1단 주행상태이면, 2단 기어는 미리 들어가 준비된 상태를 유지하며, 이러한 특징으로 인하여 실제 변속 시점에서는 짝수단과 홀수단 클러치 교환만으로 변속을 한번에 구현할 수 있게 된다.For example, in the present first stage driving state, the second stage gear is pre-entered and maintained in a ready state. Due to this feature, it is possible to implement a shift at a time only by exchanging a pair of means and a hole means at an actual shift point.

상기와 같은 듀얼클러치변속기는 변속기어단과 짝수-홀수단을 조작하는 2개의 클러치 및 변속기 내부 슬리브기어와 연결된 변속러그를 작동시켜 변속이 되게끔 하는 2개의 액추에이터로 구성하며, 액추에이터의 일부분으로서 변속러그사이에 서 변속과 자동해제 및 AIL(Active Inter-Lock)기능을 수행하는 변속 메커니즘을 갖춘다.The dual clutch transmission is composed of two clutches that operate the transmission gear stage and the even-hole means, and two actuators that operate the transmission lugs connected to the inner sleeve gears of the transmission, and the transmission lugs as part of the actuator. It has a shifting mechanism that performs shifting, automatic release, and AIL (Active Inter-Lock) function.

이로 인해 상기 액추에이터는 새로운 목표 기어로 변속하는 기능과, 이전 기어를 자동으로 빼주는 기능과, 이전 기어를 자동으로 빼주면서 흔들리지 않게 록킹하는 AIL(Active Inter-Lock)기능을 반드시 구현함을 필요로 한다.This requires the actuator to implement the function of shifting to a new target gear, automatically removing the old gear, and AIL (Active Inter-Lock) function, which automatically removes and locks the previous gear. .

이에 더해, 상기 듀얼클러치변속기에는 ECU나 액추에이터 위치센서등의 불량(Fail)시에도 원하지 않는 변속단에서의 기어물림을 방지하여 변속기가 파손되지 않도록 하는 동시에, 차량이 위험한 상황으로 되지 않도록 방지할 수 있는 즉, 오작동을 방지하는 기구를 액추에이터 부위로 구비한다.In addition, the dual clutch transmission can prevent gear bites at undesired transmission stages even in the event of a failure of the ECU or actuator position sensor, thereby preventing the transmission from being damaged and preventing the vehicle from becoming a dangerous situation. That is, a mechanism for preventing malfunction is provided as an actuator part.

하지만, 상기와 같은 오작동 방지기구가 감속기 내부에 복합적인 형태로 구속 메커니즘을 구현하게 되면, 듀얼클러치변속기 구조를 복잡하게 하고 또한 원가와 중량 측면에서 불리하게 작용하므로, 가능한 듀얼클러치변속기 구조를 최대한 이용하여 보다 간단하게 구성한 오작동 방지기구의 적용을 필요로 한다.However, when the above malfunction prevention mechanism implements the restraint mechanism in a complex form inside the reducer, it complicates the dual clutch transmission structure and also adversely affects the cost and weight, thus making the most of the dual clutch transmission structure possible. Therefore, it is necessary to apply a malfunction prevention mechanism that is configured more simply.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 변속 메커니즘을 구현하는 변속러그 부위에서 변속포크쪽에 일체화시켜 시프트(Shift)시 정위치되지 않은 상태로부터 셀렉트(Select)를 구현할 수 없도록 함으로써, 듀얼클러치변속기의 내부 구조를 건드리지 않는 오작동 방지기구를 적용한 듀얼클러치변속기를 제공 함에 목적이 있다.Accordingly, the present invention has been in view of the above, by integrating the shifting fork at the shifting lug portion that implements the shifting mechanism so that a select can not be implemented from an unpositioned position at the time of shift. An object of the present invention is to provide a dual clutch transmission with a malfunction preventing mechanism that does not touch the internal structure of the dual clutch transmission.

또한, 본 발명은 변속러그와 변속포크 부위를 이용해 오작동을 방지함으로써, 단순 구조를 가지면서 별도 부품 사용에 따라 수반되는 원가와 중량의 불리함도 없는 오작동 방지기구를 적용한 듀얼클러치변속기를 제공함에 목적이 있다.In addition, an object of the present invention is to provide a dual clutch transmission by applying a malfunction preventing mechanism having a simple structure and without the disadvantages of cost and weight associated with the use of separate parts by preventing malfunction by using the shifting lug and the shifting fork portion. There is this.

Integral to one shifting fork of the first, second, and third shifting forks which operate one shifting lug of the 1-3, 2-4, 5, 6-R shifting lug in accordance with the shifting stage at the time of selection. It is characterized in that it comprises a malfunction preventing mechanism that makes it impossible to operate the shifting lug at the wrong select position.

상기 오작동방지기구는 상기 제2변속포크쪽에서 제2변속포크와 일체로 형성된다. The malfunction preventing mechanism is integrally formed with the second speed change fork at the second speed change fork.

상기 제2변속포크를 핑거레버에 결합된 상태에서 변속러그를 조작하는 제2변속포크의 앞쪽에 대해 반대부위인 뒤쪽부위에서 변속러그수용공간을 형성하는 걸림판을 이용하여 구성한다.The second shift fork is configured using a locking plate that forms a shift lug receiving space at a rear portion opposite to the front of the second shift fork for manipulating the shift lug in a state coupled to the finger lever.

상기 제2변속포크는 변속러그를 조작하는 앞쪽은 변속러그 두께와 같은 두께를 갖는 반면, 그 뒤쪽은 제2변속포크와 걸림판사이에 형성된 변속러그수용공간으로 변속러그 두께를 삽입할 수 있는 빈 공간을 갖는 구조로 이루어진다.The second shifting fork has the same thickness as the shifting lug on the front of the shifting lug, while the rear of the second shifting fork is an empty space into which the shifting lug thickness can be inserted into the shifting lug receiving space formed between the second shifting fork and the locking plate. It is made of a structure having.

이러한 본 발명에 의하면, 변속러그 부위에서 변속포크쪽에서 일체화된 오작동 방지기구를 적용하므로, 듀얼클러치변속기의 내부 구조를 건드리지 않는 오작동 방지 기능을 구현할 수 있으면서 단순한 구조를 갖는 효과를 갖는다.According to the present invention, since the malfunction prevention mechanism integrated at the shift fork side at the shift lug portion is applied, it is possible to implement a malfunction prevention function without touching the internal structure of the dual clutch transmission, and has a simple structure.

또한, 본 발명은 별도 부품을 사용하지 않고 오작동 방지 기능을 구현하므로, 별도부품 사용시 수반되는 원가와 중량에 대한 불리함도 없는 효과도 갖는다.In addition, since the present invention implements a malfunction prevention function without using a separate part, there is no disadvantage in the cost and weight accompanying the use of a separate part.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명하며, 이러한 실시예는 일례로서 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 여러 가지 상이한 형태로 구현될 수 있으므로, 여기에서 설명하는 실시예에 한정되지 않는다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

By moving, the gear shift of the transmission unit 1 is operated to the desired gear stage.

도 2에 도시된 바와 같이, 본 실시예에 따른 상기 오작동 방지기구(30)는 핑거유닛(10)의 제2변속포크(13)쪽에서 제2변속포크(13)와 일체로 형성한다.As shown in FIG. 2, the malfunction preventing mechanism 30 according to the present embodiment is integrally formed with the second shifting fork 13 at the side of the second shifting fork 13 of the finger unit 10.

하지만, 액추에이터를 통해 변속을 위한 정확한 위치로 셀렉트(Select)되면, 제2변속포크(13)의 회전시 변속러그수용공간(32)으로 해당된 변속러그가 삽입됨으로써, 상기 제2변속포크(13)의 셀렉트(Select)후 시프트(Shift)작동에 전혀 문제를 일으키지 않게 된다.However, when the selected position is selected to the correct position for shifting through the actuator, a corresponding shift lug is inserted into the shifting lug receiving space 32 when the second shifting fork 13 is rotated, whereby the second shifting fork 13 After select, the shift does not cause any problem.

이와 같이 본 실시예는 변속러그를 셀렉트(Select)하는 제1·2·3변속포크(12,13,14)가 잘못된 셀렉트(Select)위치에 있게 되면, 1-3·2-4·5·6-R단 변속러그(21,22,23,24)중 해당된 변속러그를 통해 접촉되어 구속됨으로써 오작동을 방지할 수 있으므로, 듀얼클러치변속기의 내부구조를 건드리지 않고 그 구성에서도 원가와 중량을 불리하게 하는 별도 부품을 사용하지도 않고 오작동방지기구(30)를 장착할 수 있게 된다.Thus, in this embodiment, when the first, second, third shifting forks 12, 13, and 14 for selecting the shift lug are positioned at the wrong select position, they are 1, 3, 2, 4, 5, Since the malfunction can be prevented by contacting and restraining the 6-R gear shifting lugs (21, 22, 23, 24) through the corresponding shifting lugs, the cost and weight of the dual clutch transmission are not touched. The malfunction prevention mechanism 30 can be mounted without using a separate component.
