Abstract

PURPOSE: Assembling structure of a speed drive gear for a manual transmission is provided to prevent damage of the driven gear from load of a cable, and to improve the reliability and the durability of the drive gear by forming the assembling clearance between the speed drive gear and the differential case. CONSTITUTION: A differential pinion gear and a differential side gear are surrounded by a differential case(10), and a speed drive gear(20) is placed outside the differential case. The displacement of the speed drive gear is restricted by a stop ring. A key projection(21) is protruded in the speed drive gear to restrict the speed drive gear from turning, and a slide groove(30) is recessed in the differential case to contain the key projection with the specific movement angle. The speed drive gear is engaged with a speed driven gear actively and quickly by circumferentially moving right and left from the differential case within the movement angle.

수동변속기의 스피드 드라이브기어의 체결구조Fastening structure of speed drive gear of manual transmission

본 발명은 수동변속기의 스피드 드라이브기어의 체결구조에 관한 것으로, 더 상세하게는 스피드 드라이브기어의 손상을 방지하고 내구성을 향상시킬 수 있도록 발명된 것이다.The present invention relates to a fastening structure of a speed drive gear of a manual transmission, and more particularly, to prevent damage to the speed drive gear and to improve durability.

일반적으로 차량의 속도계는 변속기의 출력축으로 결합된 스피드 드라이브기어와이에 치합된 드라이븐기어 어셈블리를 거쳐 속도계 사이를 연결하는 플랙시블 케이블이 회전을 전달하여 속도 계측이 이루어 지도록 구성된다.In general, the speedometer of a vehicle is configured such that speed measurement is performed by transmitting a rotation by a flexible cable connecting the speedometer through a drive gear assembly coupled to a speed drive gear coupled to an output shaft of a transmission.

스피드 드라이브기어(20)는 도 1 및 도 4에서와 같이 디퍼런션피니언기어(11)와 디퍼런셜사이드기어(12)를 감싸는 디퍼런셜케이스(10)의 외측에 설치된다.The speed drive gear 20 is installed outside the differential case 10 surrounding the differential pinion gear 11 and the differential side gear 12 as shown in FIGS. 1 and 4.

이 스피드 드라이브기어(20)는 도 2 및 도 3에서와 같이 반달형의 키이돌기(21)가 형성되어 디퍼런셜케이스(10)와 회동 방지된 상태로 결합되고, 스피드 드라이븐기어 취부시 드라이브기어(20)는 회전할 수 없는 상태에서, 드라이븐기어가 약간 회전하므로 각 치차가 맞게 조정되는 것이다.2 and 3, the speed drive gear 20 is formed with a half-moon shaped key protrusion 21, which is coupled to the differential case 10 in a state where it is prevented from rotating, and the drive gear 20 when the speed drive gear is mounted. ) Can not be rotated, the drive gear is rotated slightly, so each gear is adjusted to fit.

이와같이 종래 드라이브기어(20)의 구조에 의하면, 조립 유격이 없다.Thus, according to the structure of the conventional drive gear 20, there is no assembly play.

따라서, 드라이븐기어가 케이블의 부하에 의해 부하를 갖게 있는 상태이므로 드라이븐기어가 잘 돌아가지 않을 때는 드라이븐기어의 치차들에 손상을 주어 내구수명이 급격히 저하되는 등의 폐단이 있었던 것이다.Therefore, since the drive gear has a load due to the load of the cable, when the drive gear does not rotate well, the gears of the drive gear are damaged and the endurance life is sharply reduced.

본 발명의 목적은 조립유격을 갖도록 하여 드라이븐기어의 손상을 방지할 수 있도록 한 수동변속기의 스피드 드라이브기어의 체결구조를 제공하는 데 있다.An object of the present invention is to provide a fastening structure of a speed drive gear of a manual transmission to have an assembly clearance to prevent damage to the drive gear.

본 발명의 다른 목적은 내구성과 제품의 신뢰성이 향상되도록 한 수동변속기의 스피드 드라이브기어의 체결구조를 제공하는 데 있다.Another object of the present invention is to provide a fastening structure of a speed drive gear of a manual transmission in which durability and product reliability are improved.

이러한 본 발명의 목적은, 디퍼런션피니언기어(11)와 디퍼런셜사이드기어(12)를 감싸는 디퍼런셜케이스(10)의 외측에 스피드 드라이브기어(20)가 위치되어키이돌기(21)에 의해 디퍼런셜케이스(10)와 회동 방지토록 된 것에 있어서;The object of the present invention is that the speed drive gear 20 is located on the outer side of the differential case 10 surrounding the differential pinion gear 11 and the differential side gear 12 so that the differential case is provided by the key protrusion 21. In preventing rotation with (10);

상기 디퍼런셜케이스(10)에 상기 키이돌기(21)를 수용하는 슬라이드홈(30)을 소정의 유동각(θ)을 갖도록 성형하는 것에 의해 달성된다.It is achieved by molding the slide groove 30 for receiving the key protrusion 21 in the differential case 10 to have a predetermined flow angle θ.

따라서, 스피드 드라이브기어(20)가 디퍼런셜케이스(10)로 부터 조립유격을 갖게 되므로, 케이블의 부하에 의한 드라이븐기어의 손상을 방지할 수 있다.Therefore, since the speed drive gear 20 has an assembly clearance from the differential case 10, damage to the drive gear due to the load of the cable can be prevented.

또, 드라이브기어(20)의 내구성과 신뢰성이 향상되는 것이다.In addition, durability and reliability of the drive gear 20 are improved.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의해 상세하 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 4는 본 발명의 스피드 드라이브기어(20)가 디퍼런셜케이스(10) 외측으로 설치되고, 멈춤링(15)으로 이탈이 방지된 상태를 보이고 있다.4 shows a state in which the speed drive gear 20 of the present invention is installed outside the differential case 10 and is prevented from being separated by the stop ring 15.

상기 디퍼런셜케이스(10)는 그 내부로 디퍼런션피니언기어(11)와 디퍼런셜사이드기어(12)를 감싸게 되고, 외측에는 속도계에 바퀴의 회전수를 전달하기 위한 수단으로 디퍼런션피니언기어(11)가 결합된다.The differential case 10 surrounds the differential pinion gear 11 and the differential side gear 12 therein, and the differential pinion gear 11 as a means for transmitting the rotational speed of the wheel to the speedometer on the outside. ) Are combined.

이 스피드 드라이브기어(20)에는 내경에 반달형의 키이돌기(21)가 돌출되고, 디퍼런셜케이스(10)에는 이 키이돌기(21)에 조립되기 위한 슬라이드홈(30)이 파여지게 된다.The speed drive gear 20 has a half moon-shaped key protrusion 21 protruding from its inner diameter, and the differential case 10 is provided with a slide groove 30 for assembling the key protrusion 21.

이때, 이 슬라이드홈(30)은 키이돌기(21)가 좌우로 유동되도록 하는 소정의 유동각(θ)을 형성하게 된다.At this time, the slide groove 30 forms a predetermined flow angle θ such that the key protrusion 21 flows from side to side.

따라서, 스피드 드라이브기어(20)가 디퍼런셜케이스(10)로 부터 원주방향으로 상기 유동각(θ) 범위내에서 좌우로 유동되어 스피드 드라이븐기어의 취부시 치차의 물림이 원활하고 신속하게 이루어 질 수 있는 것이다.Therefore, the speed drive gear 20 flows from the differential case 10 to the circumferential direction in the circumferential direction from side to side within the flow angle θ so that the gear bite can be smoothly and quickly made when the speed drive gear is mounted. It is.

또, 속도계 케이블의 부하로 스피드 드라이븐기어가 부하를 갖고 있을 때도 치차의 손상을 방지하게 되는 것이다.In addition, even when the speed drive gear has a load due to the speedometer cable load, damage to the gear is prevented.

상기와 같은 본 발명은, 스피드 드라이브기어(20)가 디퍼런셜케이스(10)로 부터 조립유격을 갖게 되므로, 케이블의 부하에 의한 드라이븐기어의 손상을 방지할 수 있다.In the present invention as described above, since the speed drive gear 20 has an assembly clearance from the differential case 10, it is possible to prevent damage to the drive gear due to the load of the cable.

또, 드라이브기어(20)의 내구성과 신뢰성이 향상되는 등의 매우 유용한 발명인 것이다.In addition, it is a very useful invention such that durability and reliability of the drive gear 20 are improved.
