본 발명은 수동변속기에 관한 것으로, 특히 후진변속시에 기어치합소음을 저감시키고 기어의 파손을 방지할 수 있도록 후진동기치합장치를 갖춘 수동변속기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual transmission, and more particularly, to a manual transmission having a reverse oscillation engagement device to reduce gear tooth noise during reverse shift and prevent gear breakage.

종래 수동변속기의 후진변속기구는 제4도에 도시된 것과 같이, 변속기입력축(1)에 제1후진기어(2)가 고정되게 설치되고, 이 제1후진기어(2)와 선택적으로 치합되도록 후진아이들기어(3)가 후진아이들기어축(4)에 미끄럼이동 가능하도록 설치되며, 상기 후진 아이들기어(3)와 선택적으로 치합되는 제2후진기어(5)는 출력축(6)에 고정되게 설치되어, 운전자가 변속레바를 후진 조작하게 되면 시프트 포크를 매개로 후진아이들기어(3)가 후진아이들기어축(4)을 따라 화살표방향으로 미끄럼이동되면서 입력축(1)의 제1후진기어(2)와 출력축(6)의 제2후진기어(5)와 동시에 치합됨으로써, 입력출(1)의 회전구동력이 제1후진기어(2)와 후진아이들기어(3) 및 제2후진기어(5)를 통해 출력축(6)으로 전달되어 후진구동이 이루어지게 된다.As shown in FIG. 4, the reverse transmission mechanism of the conventional manual transmission is provided with a first reverse gear 2 fixed to the transmission input shaft 1, and the reverse children to be selectively engaged with the first reverse gear 2. The gear 3 is installed to be slidable to the reverse idler gear shaft 4, and the second reverse gear 5 to be selectively engaged with the reverse idler gear 3 is fixed to the output shaft 6, When the driver reverses the shift lever, the reverse idler gear 3 slides along the reverse idler shaft 4 in the direction of the arrow via the shift fork, and the first reverse gear 2 and the output shaft of the input shaft 1 are moved. By being engaged with the second reverse gear 5 of (6) at the same time, the rotational driving force of the input output 1 is transmitted to the output shaft via the first reverse gear 2, the reverse idle gear 3 and the second reverse gear 5. It is transmitted to (6) and reverse driving is performed.

그런데 상기한 후진변속과정에 운전자가 클러치페달을 밟아서 클러치를 끊은 상태에서도 변속기 입력축(1)은 회전관성으로 인해 계속 회전되고 있기 때문에 변속기 입력축(1)과 출력축(6) 및 후진아이들기어축(4)은 서로 회전수가 다르게 되는 바, 이러한 상태에서 후진아이들기어축(4)의 후진아이들기어(3)가 입력축(1)의 제1후진기어(2) 및 출력축(6)의 제2후진기어(5)와 동시에 치합되도록 미끄럼이동되면 상기한 회전수차이로 인해 기어이빨들이 서로 부딪쳐 치함소음이 발생될 뿐 아니라 기어가 정확하게 치합되지 못하거나 경우에 따라 기어이빨이 파손되는 등의 결점이 있었다.However, since the transmission input shaft 1 continues to rotate due to the rotational inertia even when the driver presses the clutch pedal in the reverse shift process, the transmission input shaft 1, the output shaft 6, and the reverse idler gear shaft 4 Since the rotational speeds are different from each other, the reversing idle gear 3 of the reversing idle gear shaft 4 is the first reversing gear 2 of the input shaft 1 and the second reversing gear of the output shaft 6. 5) When the sliding movement to be engaged at the same time, the gear teeth hit each other due to the above-mentioned rotation aberration, not only noise generated noise, but also there was a defect such as the gear is not accurately engaged or in some cases the gear teeth are broken.

이에 본 발명은 상기한 종래 수동변속기의 후시진변속기구가 갖고 있는 결점을 해소하기 위해 발명된 것으로, 후진변속시에 치합소음이 적고 기어들이 정확하게 치합될 수 있을 뿐 아니라 기어의 충돌파손을 미연에 방지할 수 있도록 된 후진동기치합장치를 갖춘 수동변속기를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the drawbacks of the above-mentioned conventional manual transmission, and the rear shifting mechanism is low. There is less gearing noise during the reverse shift, the gears can be accurately engaged, and the collision damage of the gears is delayed. It is an object of the present invention to provide a manual transmission with a reverse oscillation coupling device that can be prevented.

상기한 바의 목적을 달성하기 위한 본 발명은, 후진아이들기어축이 클러치하우징과 변속기 케이스에 끼워져 지지됨과 더불어 이 후진아이들기어축에 후진아이들구동기어가 출력축의 공회전가능한 제1기어와 상시치합되게 설치되고, 이 제1기어는 입력축에 고정된 제1기어와 상시 치합되게 설치되면서 상기 후진아이들구동기어는 동기치합장치를 매개로 후진아이들피동기어와 선택적으로 일체로 연결되게 설치되고, 이 후진아이들피동기어는 입력축에 공회전가능한 제3기어와 상시치합되게 설치되는 한편, 이 제3기어는 출력축에 고정된 제3기어와 상시치합되게 설치된 구조로 되어 있다.The present invention for achieving the above object, the reverse idler gear shaft is supported by the clutch housing and the transmission case, and the reverse idler gear shaft on the reverse idler gear shaft is in constant mesh with the first idler of the output shaft. The first gear is installed to be in constant mesh with the first gear fixed to the input shaft, and the reverse idler driving gear is selectively connected to the reverse idler driven gear via a synchronous matching device. The driven gear is installed in the input shaft so as to be in constant mesh with the third gear that can be idle, while the third gear has a structure in which it is always arranged in the match with the third gear fixed to the output shaft.

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 후진동기치합장치가 장착된 수동변속기의 일부절개 전개도이고, 제2도는 제1도의 A-A선 단면도, 제3도는 제1도의 B-B선 단면도인 바, 종래 후진변속기구를 나타내는 제4도와 동일한 부위에는 동일한 참조부호를 표시하고 그에 대한 자세한 설명은 생략하기로 한다.1 is a partially cut-away view of a manual transmission equipped with a reverse oscillation coupling device according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB of FIG. Like reference numerals are used to designate like parts in FIG. 4 and detailed description thereof will be omitted.

즉 후진아이들기어축(3)은 클러치하우징(8)과 변속기케이스(9)에 양쪽단부가 끼워져 지지되고, 이 후진아이들기어축(3)에 후진아이들구동기어(7)가 제2도에 도시된 것과 같이, 출력축(5)의 공회전하는 제1기어(10)와 상시 치합되게 설치되고, 이 출력축(5)의 제1기어(10)는 입력축(1)에 고정된 제1기어(11)와 상시치합되게 설치되며, 상기 후진아이들구동기어(7)는 동기치합장치(12)를 매개로 후진아이들피동기어(13)와 선택적으로 연결되게 설치되고, 이 후진아이들피동기어(13)는 제3도에 도시된 것과 같이 입력축(1)에서 공회전하는 제3기어(14)와 상시치합되게 설치되며, 이 제3기어(14)는 출력축(6)에 고정된 제3기어(15)와 상시치합되게 설치되어 있다.In other words, the reverse idler gear shaft 3 is supported by both ends of the clutch housing 8 and the transmission case 9, and the reverse idler drive gear 7 is shown in FIG. As described above, the first gear 10 of the output shaft 5 is installed to be in constant mesh with the first gear 10, and the first gear 11 of the output shaft 5 is fixed to the input shaft 1. And the reverse idler drive gear (7) is installed to be selectively connected to the reverse idler driven gear (13) via the synchronous gearing device (12), and the reverse idler driven gear (13) As shown in FIG. 3, the third gear 14 is installed at all times with the third gear 14 idling in the input shaft 1, and the third gear 14 is always in contact with the third gear 15 fixed to the output shaft 6. It is installed properly.

그리고 상기 동기치합장치(12)는 공지의 동기치합장치로서 싱크로나이저링(12a)과 싱크로나이저 스프링(12b), 싱크로나이저 키이(12c) 및 슬라이브(12a)를 갖춘 구조로 되어 있다.The synchronizing gear 12 is a known synchronizing gear and has a structure including a synchronizer ring 12a, a synchronizer spring 12b, a synchronizer key 12c, and a slave 12a.

따라서 상기한 구조로 된 후진변속기구의 동력전달경로는 운전자가 변속레바를 후진조작하게 되면 상기 슬리이브(12d)가 일정거리만큼 이동해서 후진아이들피동기어(13)에 형성된 스플라인부와 결합되어 후진아이들구동기어(7)가 후진아이들피동기(13)가 일체로 연결되는데, 이러한 상태에서 제4도에 도시된 것과 같이 변속기 입력축(1)의 제1기어(11)로부터 출력축(6)의 공회전하는 제1기어(10)를 통해 후진아이들기어축(3)의 후진아이들구동기어(7)와 동기치합장치(12)를 거쳐 후진아이들피동기어(13)로 전달된 다음에 다시 변속기 입력축(1)에서 공회전하는 제3기어(14)를 통해 출력축(6)에 고정된 제3기어(15)로 전달되게 된다.Therefore, when the driver reverses the shift lever, the power transmission path of the reverse shift mechanism having the above-described structure moves the sleeve 12d by a predetermined distance and is coupled with the spline part formed in the reverse idle driven gear 13 to reverse the children. The drive gear 7 is integrally connected to the reverse idler drive 13, and in this state, idling of the output shaft 6 from the first gear 11 of the transmission input shaft 1 as shown in FIG. The first gear 10 is transmitted to the backward idle driven gear 7 of the reverse idler gear shaft 3 and the reverse idler driven gear 13 via the synchronous gear 12, and then again to the transmission input shaft 1. It is transmitted to the third gear (15) fixed to the output shaft (6) through the third gear (14) idling at.

상기한 후진변속조작과정에서 후진아이들구동기어(7)와 후진아이들피동기어(13)는 동기치합장치(12)를 매개로 일체로 연결되기 때문에 치합소음없이 원활하고 정확하게 연결될 뿐아니라 나머지 기어들은 모두 상시 치합되는 구조로 되어 정확한 동력전달이 이루어지게 되고, 또 상기 후진아이들구동기어(7)는 출력축(6)의 제1기어(10)와, 후진아이들피동기어(13)는 입력축(1)의 제3기어(14)와 상시치합되는 구조로 되어 이들 기어들은 헬리컬기어로 구성할 수 있으므로 기어강도가 상승될 뿐 아니라 기어소음을 저감시킬 수 있게 된다.In the reverse shifting operation, since the reverse idler drive gear 7 and the reverse idler driven gear 13 are integrally connected to each other through the synchronizing gear 12, the remaining gears are connected smoothly and accurately without noise. As the structure is always engaged, accurate power transmission is achieved, and the reverse idler drive gear 7 includes the first gear 10 of the output shaft 6 and the reverse idler driven gear 13 of the input shaft 1. Since the gears are always meshed with the third gear 14, these gears can be configured as helical gears, thereby increasing the gear strength and reducing the gear noise.

이상 설명한 바와 같이 본 발명에 따른 후진동기치합장치를 갖춘 수동변속기에 의하면, 정확하고 원활한 후진변속이 이루어지고, 기어들이 서로 부딪쳐서 치합소음을 일으키거나 파손될 염려가 전혀 없을 뿐 아니라 기어소음도 저감시킬 수 있는 효과가 있다.As described above, according to the manual transmission equipped with the reverse synchronizing device according to the present invention, accurate and smooth reverse shift is achieved, and there is no fear that the gears collide with each other to cause crush noise or breakage, as well as reduce gear noise. It has an effect.
