자동차용 소켓형 파킹장치{socket type parking device for vehicles}Socket type parking device for vehicles

본 발명은 자동차용 파킹장치에 관한 것으로, 더욱 상세하게는 출력샤프트에 육각홈을 형성하고, 이 육각홈에 끼워져 고정될 수 있는 육각볼트를 갖춘 파킹기구를 설치하여 출력샤프트의 회전력을 고정하도록 됨에 따라, 출력샤프트의 단속을 확실하게 할 수 있음은 물론, 내구성이 향상되는 자동차용 소켓형 파킹장치에 관한 것이다.The present invention relates to a parking device for an automobile, and more particularly, to form a hexagonal groove in the output shaft, and to install a parking mechanism having a hexagonal bolt that can be fixed to the hexagonal groove to fix the rotational force of the output shaft. Accordingly, the present invention relates to an automobile socket-type parking device that can securely interrupt an output shaft and of which durability is improved.

일반적으로 차량의 제동장치는 주행중인 자동차를 감속 또는 정지시키고 동시에 주차상태를 유지하기 위한 것으로 마찰력을 이용하여 제동작용을 할 수 있게 된다.In general, the braking device of a vehicle is to decelerate or stop a driving car and maintain a parking state at the same time, so that a braking action can be performed using a friction force.

이러한 제동장치는 제동작용력이 확실해야되고, 제동효과를 초래하는 신뢰성과 내구성이 크고, 점검 및 정비가 용이해야 된다.Such a braking device should be sure of braking force, reliable and durable, and easy to inspect and maintain, causing a braking effect.

상기한 제동장치에는 운전자의 발로 조절하는 풋브레이크와 손으로 조작하는 핸드브레이크(파킹레버)가 있고, 이 핸드브레이크는 주로 주차용으로 사용되거나 제동장치의 고장시 비상용으로 사용된다.The braking device includes a foot brake controlled by the driver's foot and a hand brake (parking lever) which is operated by hand, which is mainly used for parking or for emergency in case of breakdown of the braking device.

이러한 종래의 핸드브레이크는 도 3에 도시된 것과 같이, 출력축에 형성된 출력측 기어(10-1)와 맞물려 있는 파킹기어(11)를 파킹 스프라그(20)가 걸려짐에 의해 출력축의 회전을 막는 구조로 되어있다. 즉, 경사로 주차시 주차브레이크(30)를 당기게 되면 파킹 스플라그(20)가 파킹기어(11)와 맞물리게 되면서 출력축이 고정되어 차량을 일시적으로 제동하게 된다.As shown in FIG. 3, the conventional hand brake has a structure in which the parking gear 11 engaged with the output gear 10-1 formed on the output shaft prevents the rotation of the output shaft by engaging the parking sprag 20. It is. That is, when the parking brake 30 is pulled when parking on the slope, the parking sprocket 20 is engaged with the parking gear 11 and the output shaft is fixed to temporarily brake the vehicle.

그런데 상기 핸드브레이크의 구조는 파킹기어(11)의 이빨 하나에 파킹 스플라그(20)가 걸려 있어, 이 파킹 스플라그(20)의 이빨이 손상되거나 파킹기어(11)의이빨이 손상될 경우, 파킹 스플라그(20)가 파킹기어(11)에서 이탈되어 파킹기능이 상실하게 된다. 이는 자칫 심각한 사고로 이어질 수 있다.By the way, the structure of the hand brake is a parking sprocket 20 is hung on one of the teeth of the parking gear 11, if the teeth of the parking sprocket 20 is damaged or the teeth of the parking gear 11, The parking sprocket 20 is separated from the parking gear 11 and the parking function is lost. This can lead to serious accidents.

상기와 같은 문제점을 다소나마 해소하기 위해서는 파킹기어 및 파킹 스플라그의 안전계수를 충분하게 부여하여 상기 부품들을 설계하여 제작하여야만 된다. 이는 부품의 고급화로 이어져 제품단가가 높게 되는 새로운 문제점이 발생되게 된다.In order to alleviate the above problems, the parts must be designed and manufactured with sufficient safety factors of the parking gear and the parking sprocket. This leads to high quality parts, which causes new problems of high product cost.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 출력축에 육각홈을 형성하고, 이 육각홈에 끼워져 고정될 수 있는 육각볼트를 갖춘 파킹기구를 설치하여 출력축의 회전력을 고정하도록 됨에 따라, 출력축의 단속을 확실하게 할 수 있음은 물론, 내구성이 향상되도록 된 자동차용 소켓형 파킹장치를 제공함에 그 목적이 있다.Accordingly, the present invention was invented to solve the above problems, and to form a hexagonal groove in the output shaft, and to install a parking mechanism having a hexagonal bolt that can be fixed to the hexagonal groove to fix the rotational force of the output shaft It is an object of the present invention to provide an automobile socket-type parking device that can secure the interruption of the output shaft as well as improve durability.

상기와 같은 목적을 달성하기 위한 본 발명은 출력축에 형성된 출력측 기어와 맞물려 있는 파킹기어를 파킹 스프라그가 걸려짐에 의해 출력축의 회전을 막는 자동차용 파킹장치에 있어서, 상기 출력축의 단부면의 중심부에 육각홈이 형성되고, 이 육각홈에 끼워져 걸리게 되는 파킹돌기를 갖춘 파킹장치가 형성되는 것을 특징으로 한다.The present invention for achieving the above object is a vehicle parking device for preventing the rotation of the output shaft by the parking sprag is caught in the parking gear meshed with the output side gear formed on the output shaft, in the center of the end surface of the output shaft Hexagonal grooves are formed, characterized in that the parking device having a parking projection to be caught in the hexagonal grooves is formed.

따라서 상기 육각 파킹돌기에 의해서 출력축의 단속이 이루어지므로, 구조가 간단하면서도 견고하면서 확실한 단속이 이루어진다.Therefore, the interruption of the output shaft is made by the hexagonal parking projection, the structure is simple, yet solid and reliable interruption.

도 1은 본 발명에 따른 소켓형 파킹장치의 개략적인 구성도이다.1 is a schematic configuration diagram of a socket-type parking device according to the present invention.

도시된 바와 같이, 본 발명은 출력측 기어(1-1)를 갖추고 출력축(1)의 단부면의 중심부에 육각홈(1-2)이 형성되어 있다. 이 육각홈(1-2)에 끼워져 걸리게 되는 파킹돌기(2-1)를 갖춘 파킹장치(2)가 형성되어 있다. 따라서 상기 출력축(1)의 단속은 상기 파킹장치(2)의 파킹돌기(2-1)가 육각홈(1-2)에 귀속여부에 따라 결정된다. 여기서 상기 파킹기구인 파킹장치(2)는 도 2에 상세하게 도시된 단면도와 같이, 파킹돌기(2-1)가 형성되어 있고, 이 파킹돌기(2-1)의 전진 및 후진을 하도록 도와주는 스프링(2-3) 및 리테이너(2-4)를 갖추게 된다. 이들은 파킹기구 리턴용 피스톤(2-2)에 내장되게 된다.As shown, the present invention has an output side gear 1-1 and a hexagonal groove 1-2 is formed at the center of the end face of the output shaft 1. A parking device 2 having a parking protrusion 2-1, which is fitted into the hexagonal groove 1-2, is formed. Therefore, the interruption of the output shaft 1 is determined depending on whether or not the parking projection 2-1 of the parking device 2 belongs to the hexagonal groove 1-2. Here, the parking device 2, which is the parking mechanism, is formed with a parking protrusion 2-1, as shown in detail in FIG. 2, and helps to move the parking protrusion 2-1 forward and backward. Springs 2-3 and retainers 2-4 are provided. These are built in the parking mechanism return piston 2-2.

이렇게 형성된 파킹장치(2)의 작동은 먼저, 주차브레이크(3)를 작동시키게 되면 유압장치(4)가 작동하여 스프링(2-3)이 파킹돌기(2-1)를 밀게 되면서, 이 파킹돌기(2-1)가 출력축(1)의 육각홈(1-2)에 삽입되고, 이것에 의해 출력축(1)이 고정되게 되어 파킹기능을 수행하게 된다.The operation of the parking device 2 formed in this way, when the parking brake 3 is operated first, the hydraulic device 4 is operated so that the spring 2-3 pushes the parking protrusion 2-1, and this parking protrusion (2-1) is inserted into the hexagonal groove (1-2) of the output shaft (1), thereby fixing the output shaft (1) to perform the parking function.

상기 파킹기능의 해제는 상기와 역순으로 작동하여 수행하게 된다.The release of the parking function is performed in the reverse order to the above.

여기서 상기 파킹장치(2)의 작동이 하나의 육각볼트를 이용하므로 구조가 간단해짐은 물론 강도면에서도 유리해진다.Here, the operation of the parking device 2 uses a single hexagon bolt, which simplifies the structure and is advantageous in terms of strength.

이상과 같이 상세하게 설명된 본 발명에 의하면, 출력축에 육각홈을 형성하고, 이 육각홈에 끼워져 고정될 수 있는 육각볼트를 갖춘 파킹기구를 설치하여 출력축의 회전력을 고정하도록 됨에 따라, 출력축의 단속을 확실하게 할 수 있음은 물론, 구조가 간단해지며 내구성이 향상되는 효과가 있다.According to the present invention described in detail as described above, by forming a hexagonal groove in the output shaft, and to install a parking mechanism having a hexagonal bolt that can be fitted and fixed to the hexagonal groove to fix the rotational force of the output shaft, Of course, it can be assured, of course, the structure is simple and the durability is improved.
