차량 차동장치용 캐리어 직각도 측정장치 및 방법 {measuring devicd and method of carrier for car differential}Carrier squareness measuring device and method for vehicle differential device {measuring devicd and method of carrier for car differential}

본 발명은 차량 차동장치용 캐리어 직각도 측정장치 및 방법에 관한 것이다.The present invention relates to an apparatus and method for measuring carrier squareness for a vehicle differential.

일반적으로, 차동기어(differential gear)는 기어전동 장치의 한 종류를 말하는 것으로, 차동기어장치라고도 한다. 두 개의 기어가 서로 맞물려서 회전함과 동시에, 기어축도 한쪽의 기어축을 중심으로 하고, 다른 쪽의 기어축이 회전할 경우, 이와 같은 기어의 조합을 유성기어장치라고 한다. 중앙에 있는 기어를 태양기어라고 하는데, 태양기어의 주위를 유성기어가 회전한다. Generally, differential gear refers to a type of gear transmission, also called a differential gear. When two gears are engaged with each other and rotate, at the same time the gear shaft is centered on one gear shaft and the other gear shaft rotates, such a combination of gears is called a planetary gear device. The gear in the center is called a sun gear, and the planetary gear rotates around the sun gear.

태양기어축·유성기어축 및 그것들을 잇는 링크 중의 어느 2개에 운동을 주면, 다른 하나는 그 2개의 운동을 동시에 받아 회전한다. 이와 같은 기어장치를 차동기어장치라고 한다.When two of the sun gear shafts and the planetary gear shafts and the links connecting them are given a motion, the other receives the two motions simultaneously and rotates. Such a gear device is called a differential gear device.

자동차의 뒤차축을 구동하는 데 사용되는 차동기어는 이것의 응용례이다. 이것은 태양기어와 유성기어가 베벨기어로 되어 있다. 차동기어장치라고 하면 이 베벨기어식을 가리키는 경우도 있다. 차동 대(大)기어에 뒤차축을 연결하고, 차동 소(小)기어와 맞물린 것이다. The differential gear used to drive the rear axle of an automobile is an application of this. This is a sun gear and planetary gear bevel gear. Differential gear units may refer to this bevel gear type. The rear axle is connected to the differential large gear and meshed with the differential small gear.

직진할 때는 소기어는 공전하는 기어케이스와 함께 회전하여 대기어를 회전시킨다. 자동차가 방향을 바꿀 때에는 소기어는 공전과 자전을 하고, 바깥쪽에 있는 대기어를 빠르게, 안쪽에 있는 대기어를 느리게 회전시켜 바퀴가 미끄러지지 않게 한다. When going straight, the small gear rotates with the idle gear case to rotate the standby gear. When the car changes direction, the small gear rotates and rotates, and the outer gear is rotated quickly and the inner gear is rotated slowly to prevent the wheels from slipping.

상기와 같은, 차동기어를 이용한 차동 장치(Differential)는 오른쪽이나 왼쪽으로 선회주행을 한다든지, 상하 방향으로 요철이 있는 도로를 주행하는 경우에는 오른쪽 바퀴와 왼쪽 바퀴의 이동 거리가 달라지게 됨에 따라, 차량이 주행할 때 오른쪽 바퀴와 왼쪽 바퀴가 똑같은 거리를 이동하지는 않는 경우에 오른쪽 바퀴와 왼쪽 바퀴가 동일하게 회전한다면, 더 먼 거리를 이동해야 하는 바퀴는 제대로 회전할 수 없고 미끄러지는 슬립(Slip) 현상이 발생한다.As described above, a differential device using a differential gear (Differential) when turning to the right or left, or when driving on a road with unevenness in the vertical direction, the distance between the right wheel and the left wheel is changed, If the right and left wheels are turning the same when the vehicle is driving, and the right and left wheels are not traveling the same distance, the wheel that needs to travel longer distances will not be able to rotate properly and will slip. Phenomenon occurs.

상기 슬립현상이 발생되면 바퀴로부터 노면에 전달되는 동력이 없어지며, 조종성도 상실되게 됩니다. 따라서, 이런 상황에서는 오른쪽 바퀴와 왼쪽 바퀴의 회전수를 차이나게 하여 어느 한쪽 바퀴에서라도 슬립이 발생하지 않도록 유성기어로 조합된 기어비를 이용하여 좌,우 바퀴의 회전속도에 차이를 주어 슬립이 일어나지 않고 원활한 바퀴 회전을 가능하게 하는 차동장치(Differential)가 개발되어 사용되고 있다.If the slip phenomenon occurs, the power transmitted from the wheel to the road surface is lost, and the maneuverability is lost. Therefore, in this situation, the rotation speed of the left and right wheels is not slipped by using a gear ratio combined with planetary gears so that the number of revolutions of the right and left wheels is different so that slip does not occur on either wheel. Differentials have been developed and used to enable smooth wheel rotation.

이와 같은, 차동장치는 자동차가 카브를 돌때 좌우의 바퀴가 미끄럼을 일으키지 않고 원활하게 회전하기 위해서는 외측 바퀴는 내측 바퀴보다 빠르고 또한 많이 회전하여야 하며, 또 요철의 노면을 주행해야 하는 경우에도 좌우 바퀴의 회전수가 항상 변화하여야 하는 것으로, 축을 두개로 분할하여 좌우 별개로 하고 그 중 앙부에 차동기어를 설치하여, 주행중에 차량이 선회하거나 노면에 요철이 있는 경우 좌우의 바퀴에 자동적으로 회전차를 주어서(회전차가 생기지 않으면 좌우의 어느쪽 바퀴가 슬립을 일으켜 원활한 주행을 할 수 없게 된다)원활한 주행을 할 수 있도록 한 것으로, 통상 종감속기어장치와 일체가 되어 액슬 하우징에 장치된다.As such, the differential device requires that the outer wheels rotate faster and more than the inner wheels in order to smoothly rotate the left and right wheels without slipping when the car rotates the car cab. The number of revolutions should always be changed, and the shaft is divided into two and left and right separately, and the differential gear is installed at the center of the wheel.If the vehicle turns or there is irregularities on the road, If a wheel does not occur, either of the left and right wheels will slip, and smooth driving will not be possible). A smooth driving can be performed, and it is usually integrated with the reduction gear device and installed in the axle housing.

상기의 일반적인 차동장치를 제1도를 참조하면서 살펴보면 다음과 같다.Looking at the above general differential device with reference to Figure 1 as follows.

차동장치는 케이스인 캐리어(1) 내에 조립되는 원활한 주행을 위해서 조립되는 후부와 내부 및 양측부에 결합되는 드라이브기어(2)와 축으로 구성된 차동어셈블리(3)를 결합위치에 따라 형성된 베어링(4, 5)에 결합되어 캐리어(1)의 내부에서 회전하면서 주행면의 굴곡과 선회에 따른 구동축의 회전편차를 최소화 하는 구조로 형성된다.The differential device comprises a bearing (4) formed according to the engagement position of a differential assembly (3) consisting of a drive gear (2) and a shaft coupled to the rear part and the inner and both sides assembled for smooth running in the carrier (1), which is a case (4). , 5) is formed in a structure that minimizes the rotational deviation of the drive shaft according to the bending and turning of the running surface while rotating inside the carrier (1).

상기와 같이, 차동장치의 케이스인 캐리어는 후부, 내측 및 양측에 베어링을 설치하여 기어가 형성된 축을 결합하도록 지지하는 것으로, 베어링의 지지위치에 따라 축심간의 거리 및 직각도의 공차를 유지하지 못하면 차동장치가 구동되면서 내부에 노이즈가 발생되는 문제점이 있었다.As described above, the carrier, which is a case of the differential device, supports bearings at the rear, inner, and both sides so as to couple shafts formed with gears. There was a problem that the noise is generated as the device is driven.

이에, 차동장치의 캐리어를 제조한 상태로 직각도와 축심간의 거리를 측정하여 불량률을 축소하는 검사를 3차원 형상을 이용한 3차원 측정기를 통해서 직각도와 축간거리를 측정하여 사용하여 왔다.Therefore, the test for reducing the defective rate by measuring the distance between the right angle and the shaft center while manufacturing the carrier of the differential device has been used by measuring the right angle and the distance between the axes through a three-dimensional measuring machine using a three-dimensional shape.

그러나, 3차원측정기를 이용한 종래의 차동장치용 캐리어 측정방법은 고가의 장비인 3차원 측정기를 이용하여 축간거리와 직각도를 측정하여야 함으로써, 측정에 따른 비용이 증대되는 문제점이 있었다.However, the conventional method for measuring a carrier for a differential device using a three-dimensional measuring device has a problem in that the cost according to the measurement is increased by measuring the distance between the axis and the squareness using a three-dimensional measuring device which is expensive equipment.

또한, 종래의 차동장치용 캐리어 측정방법은 3차원으로 캐리어의 형상을 전체적으로 코드화 한 상태로 직각도와 축간거리를 측정하는 것으로, 제조되는 캐리어를 하나씩 3차원의 입체화 하여 측정함에 따라 캐리어의 제조 속도에 비해 측정속도가 현저하게 느려져서 생산성이 저하되는 문제점이 있었다.In addition, the conventional method for measuring a carrier for a differential device is to measure the squareness and the axial distance with the overall shape of the carrier encoded in three dimensions. Compared with the measurement speed is significantly slowed there was a problem that the productivity is lowered.

아울러, 종래의 차동장치용 캐리어 측정방법은 캐리어의 형상에 따라 3차원으로 코드화 하여 축간거리와 직각도를 측정하는 작업을 실시하기 위해서는 소정의 교육을 이수한 관리자 만이 측정이 가능함에 따라 고비용의 인력이 소요되어 측정에 따른 비용이 증대되는 문제점이 있었다.In addition, the conventional carrier measurement method for a differential device is coded in three dimensions according to the shape of the carrier to perform the task of measuring the distance between the axis and the squareness can be measured only by the administrators who have undergone a predetermined training can be expensive There was a problem that the cost is increased according to the measurement.

이와 같은, 문제점을 해결하고자 안출된 본 발명의 주목적은 차동장치용 캐리어의 조립특성에 맞도록 고정반에 측정몸체를 설치한 상태로 캐리어를 설치하고, 설치된 캐리어의 상부로 직각도와 축간거리를 측정하는 기준이 되는 직각측정부를 삽입 설치하여 높이게이지로 캐리어와 직각측정부의 직각도 값에 따라 환산표와 비교하여 측정하는 것으로 측정이 용이하고, 캐리어를 삽입한 상태로 바로 측정함에 따라 측정속도를 증대시키며, 측정이 용이함에 따라 측정비용을 축소하는데 있다.In order to solve the problems, the main purpose of the present invention is to install the carrier in a state in which the measuring body is installed on the fixed plate to match the assembly characteristics of the carrier for the differential device, and measure the right angle and the interaxial distance to the upper part of the installed carrier. It is easy to measure by comparing the conversion table according to the squareness value of carrier and right angle measuring part by inserting right angle measuring part, which is the standard to measure, and increasing measuring speed by measuring directly with carrier inserted. As a result, the measurement cost is reduced as the measurement is easier.

이와 같은, 목적을 달성하고자 안출된 본 발명의 차량 차동장치용 캐리어 직각도 측정장치는 고정삽입공 및 상기 고정삽입공과 소정 거리 떨어져 형성되어 있는 고정체결공을 구비하며, 일측이 평행한 측정고정부, 측정몸체고정공이 형성되어 있는 본체 및 상기 본체 일측에 연결되어 있으며, 상기 고정삽입공에 삽입되는 측정몸체삽입구를 포함하는 측정몸체고정구, 상기 본체의 타측에 연결되어 있는 캐리어안치구 및 상기 캐리어안치구의 일측과 연결되어 있는 직각측정안치구를 포함하는 측정몸체부, 그리고 일측이 개방되어 상기 직각측정안치구가 삽입될 수 있는 측정삽입구 및 상기 측정삽입구의 타측과 연결되어 있는 직각측정구가 형성되어 있는 직각측정부를 포함할 수 있다.
