본 고안은 자동차용 변속기에 관한 것으로, 특히 자동차를 후진시킬때 이용되는 후진변속구조를 개선시켜 변속성을 양호하게 유지시키면서 소음도 저감시킬 수 있도록 되어 있는 자동차용 변속기의 후진변속장치에 관한 것이다.The present invention relates to a transmission for a vehicle, and more particularly, to a reverse transmission of an automobile transmission that is capable of reducing noise while maintaining a good shifting performance by improving a reverse shift structure used when reversing an automobile.
일반적으로 자동차용 변속기(Transmission)는 클러치와 추진축 사이에 설치되어 자동차의 주행상태 변화에 따른 엔진의 회전력을 증대시키거나 감소시키는 역할을 하며, 자동차를 후진시키기 위한 역진장치인 후진변속 장치를 구비하고 있는바, 종래의 변속기의 후진변속 장치는 제2도에 도시된 바왁 같이 운전자가 자동차를 후진시키고자 할때, 시프트래버틀 후진변속위치에 놓게 되면 후진아이들기어(104)가 입력축(101)의 후진기어(102)와 1속기어 동기장치에 형성된 출력축(106)의 후진기어(107)에 미끄럼치합이 이루어지게 되어 후진변속상태를 유지하게 되는데, 이때 상기 입력축(101)의 후진기어(102)와 출력축(106)의 후진기어(107)의 이빨들이 서로 완전하게 맞물리기전에 상기 축들의 회전관성에 의해 충돌이 발생되어 기어파손의 위험성을 내포하고 있었다.In general, the transmission for automobiles is installed between the clutch and the propulsion shaft, and serves to increase or decrease the rotational force of the engine according to the change of the driving state of the vehicle, and has a reverse transmission that is a reverse device for reversing the vehicle. As shown in FIG. 2, when the driver tries to reverse the vehicle, the reverse idler gear 104 of the input shaft 101 is placed when the driver shifts the vehicle back to the shift gear position. A sliding gear is made to the reverse gear 107 of the output gear 106 formed in the reverse gear 102 and the 1-speed gear synchronizer to maintain the reverse shift state, wherein the reverse gear 102 of the input shaft 101 is maintained. And the teeth of the reversing gear 107 of the output shaft 106 had collisions caused by the rotational inertia of the shafts before they fully engaged with each other, which contained the risk of gear breakage. .
또한 종래의 후진변속장치는 상기 후진기어들(102, 107)이 평기어로 형성되어져 있음에 따라 기어치합시 소음이 크게 발생되어지는 문제점도 있었다.In addition, in the conventional reverse transmission device, since the reverse gears 102 and 107 are formed as spur gears, there is a problem in that noise is greatly generated when the gear is engaged.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출해 낸 것으로, 자동차의 후진변속시 시프트레버를 후진변속위치에 놓게되면 후진용 기어동기구조에 의해 변속이 부드럽게 이루어지면서 소음이 저감되어질 뿐만아니라 치합맞물림시 기어파손의 위험을 제거한 개량된 자동차용 변속기의 후진변속장치를 제공함에 그 목적이 있다.Therefore, the present invention has been devised to solve the above problems. If the shift lever is placed in the reverse shift position during the reverse shift of the vehicle, the shift is smoothly made by the reverse gear synchronous structure, and the noise is reduced as well as the gear. It is an object of the present invention to provide a reverse transmission of an improved automotive transmission that eliminates the risk of gear breakage when engaged.
상기와 같은 목적을 달성하기 위한 본 고안은 입력축의 후진기어와 출력축의 후진기어 사이에 설치되어 후진용 포크에 의해 상기 입력축과 출력축의 후진기어들에 맞물려지는 후진아이들기어를 갖춘 자동차용 변속기의 후진변속장치에 있어서, 상기 입력축의 후진기어와 상기 맞물려 있는 후진아이들기어가 설치된 후진아이들축에는 출력축의 후진기어에 상시 맞물려 있는 후진아이들축기어가 일체로 설치되고, 이 후진아이들축상에서 후진용 포크에 의해 후진아이들기어와 미끄럼 치합이 이루어지는 후진기어동기장치를 갖춘 것을 특징으로 한다.The present invention for achieving the above object is installed between the reverse gear of the input shaft and the reverse gear of the output shaft is the reverse of the automobile transmission having a reverse idler gear that is engaged with the reverse gears of the input shaft and the output shaft by the reverse fork. In the transmission, a reverse idler shaft gear, which is always engaged with the reverse gear of the output shaft, is integrally installed on the reverse idler shaft provided with the reverse gear of the input shaft and the interlocking reverse gear of the input shaft. It characterized in that it comprises a reverse gear synchronous device that is made of sliding engagement with the reverse idle gear.
이하 본 고안을 정부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the illustrated drawings.
제1도는 본 고안에 따른 자동차용 변속기에 있어서 후진변속장치부를 도시한 부분 단면도로서 도면에 도시된 바와 같이 입력축(1)의 후진기어(2)와 후진아이들축(3)의 후진아이들기어(4)는 상시 맞물림 상태를 유지하고, 이 후진아이들축(3)의 후진아이들축기어(5)와 출력축(6)의 후진기어(7)는 상시 맞물려 있다. 그리고 상기 후진아이들축(3)상에서 후진용포크(8)에 의해 후진기어동기장치(9)는 후진아이들기어(4)와 미끄럼치합이 이루어지도록 되어 있다.1 is a partial cross-sectional view showing a reverse gear unit in an automobile transmission according to the present invention, as shown in the drawing, the reverse gear 2 and the reverse idle gear 4 of the reverse idler shaft 3 of the input shaft 1. ) Is always engaged, and the reverse idler shaft gear 5 of the reverse idler shaft 3 and the reverse gear 7 of the output shaft 6 are always meshed. The reverse gear synchronous device 9 is made to be in sliding engagement with the reverse idler gear 4 by the reverse fork 8 on the reverse idler shaft 3.
이와 같이 이루어진 본 고안의 작용을 살펴보면, 자동차의 전진주행시 후진아이들축(3)의 후진기어동기장치(9)는 상기 후진아이들기어(4)에 이격되어 있으므로, 입력축(1)의 후진기어(2)에 상시 맞물려 있는 이 후진아이들기어(4)는 상기 후진아이들축(3)에서 베어링(10)에 의해 공회전함과 더불어, 이 후진아이들축(3)과 일체로 형성된 후진아이들축기어(5)는 출력축(6)의 후진기어(7)와 상시 맞물려 있기 때문에 출력축(6)의 회전운동에 의해서 상기 후진아이들축(3)도 공회전 되어지는데, 이 후진아이들축(3)은 후진아이들기어(4)와는 반대방향으로 공회전되어진다.Looking at the operation of the present invention made as described above, since the reverse gear synchronous device 9 of the reverse idler shaft (3) during the forward driving of the vehicle is spaced apart from the reverse idler gear (4), the reverse gear (2) of the input shaft (1) This reverse idler gear (4), which is always engaged with (), is idling by the bearing (10) on the reverse idler shaft (3), and the reverse idler shaft gear (5) integrally formed with the reverse idler shaft (3). Since the reversing gear 7 of the output shaft 6 is always engaged, the reversing idler shaft 3 is also idled by the rotational movement of the output shaft 6, and the reversing idler shaft 3 is the reversing idler gear 4. Idling in the opposite direction.
한편, 운전자가 시프트레버(도면에 되시되어 있지 않음)를 이용하여 자동차를 후진변속시키고자 할때 상기 출력축(6)은 일단 멈추게 되고, 이에 따라 상기 출력축(6)의 후진기어(7)에 맞울려 공회전하는 후진아이들축기어(5)도 멈추게 된다.On the other hand, when the driver tries to reverse shift the vehicle by using a shift lever (not shown in the drawing), the output shaft 6 is stopped once, and thus fits the reverse gear 7 of the output shaft 6. Resonant idle shaft gear (5) also stops ringing.
그런후에 상기 입력축(1)의 회전관성에 의해 후진아이들축(3)에서 공회전하고 있는 후진아이들기어(4)에 도면에 도시되지 않은 5단변속용로드에 부착된 후진용포크(8)가 상기 후진기어동기장치(9)를 이동시켜, 이 후진기어동기장치(9)와 후진아이들기어(4)를 동기시킨다.Then, the reverse fork 8 attached to the reversing idle gear 4, which is idle at the reverse idler shaft 3 by the rotational inertia of the input shaft 1, is attached to the five-speed transmission rod not shown in the drawing. The reverse gear synchronous device 9 is moved to synchronize the reverse gear synchronous device 9 with the reverse idle gear 4.
따라서 상기 후진기어동기장치(9)와 동기가 이루어진 후진아이들기어(4)는 후진아이들축(3)과 일체가 되어 상기 후진아이들축(3)을 회전시키고, 이 후진아이들축(3)에 일체로 형성된 후진아이들축기어(5)는 출력축(6)의 후진기어(7)에 동력을 전달하여 자동차의 후진변속주행이 이루어지게 된다.Therefore, the reverse idler gear 4 in synchronization with the reverse gear synchronizer 9 is integral with the reverse idler shaft 3 to rotate the reverse idler shaft 3 and integrally with the reverse idler shaft 3. The reverse idler shaft gear 5 is formed to transmit power to the reverse gear 7 of the output shaft 6, so that the reverse shifting of the vehicle is performed.
상기와 같은 본 고안에 따른 자동차용 변속기의 후진변속장치는 출력축(6)과 입력축(1)의 후진기어들(7, 2)사이에 설치되는 후진아이들축(3)의 후진기어동기장치(9)에 의해서 자동차의 후진변속시 후진변속작동이 원활하게 이루어져 기어파손을 방지하고 소음이 저감되어지는 잇점을 갖추게 된다.The reverse gear shift device of the vehicle transmission according to the present invention as described above is a reverse gear synchronous device of the reverse idler shaft (3) installed between the reverse shaft (7, 2) of the output shaft (6) and the input shaft (9). ), The reverse shift operation is smoothly performed when the vehicle is shifted backwards, thereby preventing gear breakage and reducing noise.
