본 고안은 자동차의 조향장치중 조향기어와 조향컬럼 조인트의 분리방지 구조에 관한 것으로, 특히 래크와 피니언형 조향기어와 조향컬럼의 플렉시블 조인트의 결합후, 분리되지 않도록 하는 구조를 간단하게 한 자동차의 조향기어와 플렉시블 조인트의 분리 방지구조에 관한 것이다.The present invention relates to a structure for preventing the separation of a steering gear and a steering column joint of a steering device of an automobile. In particular, after the coupling of a rack, a pinion type steering gear and a flexible joint of a steering column, The present invention relates to a separation prevention structure of a steering gear and a flexible joint.
일반적으로 조향장치(steering system)는 자동차의 진행방향을 운전자가 조향핸들을 돌려 자유로이 바꾸는 장치로서 조향휠, 조향컬럼, 조향축, 조향기어, 조향링키지등으로 구성되어 있다.In general, a steering system is a device in which a driver freely changes the driving direction of a vehicle by turning a steering wheel. The steering system includes a steering wheel, a steering column, a steering shaft, a steering gear, a steering linkage, and the like.
상기한 조향휠(steering wheel)은 자동차의 주행방향을 바꾸기 위한 조향핸들로서 운전자는 앞바퀴가 어떤 움직임을 하고 있는가를 조향휠로부터 감지하게 되고, 조향축(steering shaft)은 조향휠의 회전을 조향기어 박스에 전달하는 축이며, 조향기어(steering gear)는 조향휠의 회전운동을 직각에 가까운 각도로 바꿈과 동시에 조향력을 증대시켜 피트먼 암에 전달하는 것이며, 조향링키지(steering linkage)는 자동차의 진행방향을 바꾸는 장치중에서 조향기어로부터 힘을 앞바퀴에 전달하는 메커니즘의 총칭으로서, 아이들암, 피트먼암, 너클암, 타이로드등으로 구성되어 있다.The steering wheel is a steering wheel for changing the driving direction of the vehicle. The driver senses the movement of the front wheel from the steering wheel, and the steering shaft controls the steering wheel's rotation. The steering gear is a steering gear that changes the rotational movement of the steering wheel at an angle close to the right angle and increases the steering force and transmits it to the pitman arm, and the steering linkage is the driving direction of the vehicle. The mechanism that transfers the force from the steering gear to the front wheel in the gear changing device is composed of idle arm, pitman arm, knuckle arm and tie rod.
상기한 조향기어는 그 종류가 다양한데, 그 중에서 래크와 피니언형은 조향축의 선단에 피니언을 장치하여 래크를 결합시켜 피니언의 회전을 래크의 옆방향의 움직임으로 바꾸어 양단의 타이로드를 거쳐서 조향휠을 작동시키는 방식이다.There are various types of steering gears, among which the rack and pinion type is equipped with a pinion at the distal end of the steering shaft to engage the rack to change the rotation of the pinion to the lateral movement of the rack and to move the steering wheel through tie rods at both ends It works.
이 방식은 래크가 조향링키지의 일부를 구성하고 있으며 구조가 간단하여 경량화할 수 있다.In this method, the rack forms part of the steering linkage, and the structure is simple, and the weight can be reduced.
이렇게 구성된 조향장치중에서 상기한 래크와 피니언 기어가 결합내장된 조향기어 박스의 피니언 샤프트와 조향컬럼의 플렉시블 조인트의 결합구조를 제1도의 (a)와 (b)를 통하여 살펴보면 다음과 같다.The coupling structure of the pinion shaft of the steering gear box in which the rack and the pinion gear are combined and built in the steering device configured as described above will be described with reference to (a) and (b) of FIG. 1.
토션바 고정핀(3)를 가진 세레이션(serration)(1a)이 형성된 피니언 샤프트(1)와 고정용 체결구멍(2a), 볼트구멍(2b) 및 절결부(2c)가 형성된 플렉시블 조인트(2)가 세레이션(1a)과 체결구멍(2a)에 의해 결합되는 것이다.A pinion shaft 1 having a serration 1a having a torsion bar fixing pin 3, a flexible joint 2 having a fastening hole 2a for fixing, a bolt hole 2b, and a cutout 2c. ) Is coupled by the serration 1a and the fastening hole 2a.
즉, 세레이션(1a)의 토션바 고정핀(3)을 플렉시블 조인트(2)의 절결부(2c)에 맞추어 피니언 샤프트(1)를 체결구멍(2a)에 끼우고, 볼트구멍(2b)에 볼트(4)를 세레이션(1a)간의 구르브(groove)(1b)에 볼트(4)의 축(4a)이 얹혀지도록 하여 반대쪽으로 돌출된 볼트축(4a)에 너트(5)를 조여 고정시키게 된다.That is, the pinion shaft 1 is inserted into the fastening hole 2a by aligning the torsion bar fixing pin 3 of the serration 1a with the notch 2c of the flexible joint 2, and the bolt hole 2b. Fix the bolt 4 to the groove 1b between the serrations 1a so that the shaft 4a of the bolt 4 is placed on the bolt shaft 4a which protrudes to the opposite side and is fixed by tightening the nut 5. Let's go.
그러면, 피니언 샤프트(1)가 그 구르브(1b)에 의해 볼트축(1a)에 걸려 피니언 샤프트(1)가 플렉시블 조인트(2)에서 빠지지 않고 고정결합되는 것이다.Then, the pinion shaft 1 is caught by the bolt shaft 1a by the groove 1b so that the pinion shaft 1 is fixed to the flexible joint 2 without being pulled out.
상기한 토션바는 피니언 샤프트(1)내에 설치되어 있는 것이다.The torsion bar described above is provided in the pinion shaft 1.
미설명 부호 6은 조향기어 박스를 나타낸 것이다.Reference numeral 6 denotes a steering gear box.
이렇게 피니언 샤프트와 플렉시블 조인트가 결합되어 분리되지 않고 결합상태를 유지하게 된다. 여기서 결합후 분리를 방지하기 위한 피니언 샤프트의 구르브를 가공형성하는 것이 피니언 샤프트 가공형성에 있어서 또 하나의 공정이 추가되는 것이어서 그 만큼 원가상승의 요인이 되었다.In this way, the pinion shaft and the flexible joint are coupled to each other so that they remain coupled. In this case, forming a groove of the pinion shaft to prevent separation after joining is another factor in the pinion shaft forming, which is a factor of the cost increase.
따라서 본 고안은 상기한 문제점을 고려하여 피니언 샤프트와 플렉시블 조인트를 분리되지 않도록 하는 구조를 간단하게 하여 원가절감을 이루도록 한 자동차의 조향기어와 플렉시블 조인트의 분리 방지구조를 제공함에 그 목적이 있는 것이다.Accordingly, an object of the present invention is to provide a separation prevention structure of a steering gear and a flexible joint of a vehicle to achieve a cost reduction by simplifying a structure that does not separate the pinion shaft and the flexible joint in view of the above problems.
상기한 본 고안의 목적은 조향기어인 피니언 샤프트와 조향컬럼의 플렉시블 조인트의 고정결합용 볼트가 토션바 고정핀에 걸리도록 피니언 샤프트에서 토션바 고정핀을 소정높이 돌출시켜 형성하므로써 달성되는 것이다.The object of the present invention is achieved by forming a pinion shaft, which is a steering gear, and a torsion bar fixing pin from the pinion shaft so that the fixing bolt of the flexible joint of the steering column is caught by the torsion bar fixing pin.
이하, 본 고안의 기술구성과 그 작용효과를 첨부한 도면에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the technical configuration of the present invention and its effects are described in detail.
본 고안은 제2도의 (a)와 (b)에 도시한 바와 같이, 조향기어인 피니언 샤프트와 조향컬럼의 플렉시블 조인트의 결합구조에 있어서, 플렉시블 조인트(2)의 볼트구멍(2b)에 끼워지는 볼트(4)가 토션바 고정핀(20)에 걸리도록 피니언 샤프트(10)의 세레이션(11)에서 토션바 고정핀(20)을 소정높이 돌출시켜 형성한 것이다.The present invention, as shown in (a) and (b) of FIG. 2, in the coupling structure of the pinion shaft, which is a steering gear, and the flexible joint of the steering column, is fitted to the bolt hole 2b of the flexible joint 2. The torsion bar fixing pin 20 protrudes a predetermined height from the serration 11 of the pinion shaft 10 so as to catch the torsion bar fixing pin 20.
부언하자면, 본 고안은 종래 피니언 샤프트(1)의 세레이션(1a)간에 형성된 피니언 샤프트(1)와 플렉시블 조인트(2)의 고정결합용 볼트(4)가 걸리는 구르브(1b)를 없애고, 대신에 토션바 고정핀(20)을 세레이션(11)에서 돌출시켜 볼트(4)가 토션바 고정핀(20)에 의해 걸려 상기 피니언 샤프트(10)와 플렉시블 조인트(2)가 분리되지 않도록 한 것이다.In other words, the present invention eliminates the groove 1b in which the pinion shaft 1 and the fastening bolt 4 of the flexible joint 2 are formed between the serration 1a of the conventional pinion shaft 1, instead. The torsion bar fixing pin 20 protrudes from the serration 11 so that the bolt 4 is caught by the torsion bar fixing pin 20 so that the pinion shaft 10 and the flexible joint 2 are not separated. .
이와같이 세레이션(11)에서 돌출형성된 토션바 고정핀(20)에 의해서 제2도(b)에 나타낸 바와같이, 세레이션(11)에서 돌출된 토션바 고정핀(20)을 플렉시블 조인트(2)의 절결부(2c)에 맞추어 피니언 샤프트(10)를 체결구멍(2a)에 집어 넣으면, 토션바 고정핀(20)이 절결부(2c)로 통과되면서 피니언 샤프트(10)가 삽설된다.As shown in FIG. 2 (b) by the torsion bar fixing pin 20 protruding from the serration 11, the torsion bar fixing pin 20 protruding from the serration 11 is connected to the flexible joint 2. When the pinion shaft 10 is inserted into the fastening hole 2a in accordance with the cutout portion 2c of the pinion shaft, the pinion shaft 10 is inserted while the torsion bar fixing pin 20 passes through the cutout portion 2c.
이후, 볼트(4)를 볼트구멍(2b)에 끼워 너트(5)로 체결하게 되면, 토션바 고정핀(20)이 볼트축(4a)에 걸려 피니언 샤프트(10)가 플렉시블 조인트(2)에서 분리되지 않고 결합되는 것이다.Subsequently, when the bolt 4 is inserted into the bolt hole 2b to be fastened with the nut 5, the torsion bar fixing pin 20 is caught by the bolt shaft 4a so that the pinion shaft 10 is removed from the flexible joint 2. It is not separated but combined.
즉, 볼트(4)와 토션바 고정핀(20)이 피니언 샤프트(10)와 플렉시블 조인트(2)의 분리방지 역할을 하는 것이다.That is, the bolt 4 and the torsion bar fixing pin 20 serve to prevent separation of the pinion shaft 10 and the flexible joint 2.
따라서 본 고안은 토션바 고정핀만 돌출형성하는 간단한 구성에 의해 피니언 샤프트와 플렉시블 조인트를 분리되지 않도록 하므로써 구르브 가공작업을 삭제할 수 있어 원가절감을 이룩할 수 있는 것이다.Therefore, the present invention can achieve the cost reduction by eliminating the grooving process by preventing the pinion shaft and the flexible joint from being separated by the simple configuration of only the torsion bar fixing pin.
상술한 바와같이, 본 고안은 피니언 샤프트와 플렉시블 조인트의 분리방지용 볼트와 구르부중 구루브를 삭제하는 대신에 구르브 역할을 토션바 고정핀으로 대체하여 구성한 것이다.As described above, the present invention is configured to replace the role of the grooves with torsion bar fixing pins instead of removing the grooves of the pinion shaft and the flexible joint to prevent separation of the bolts and the grooves.
