Abstract

PURPOSE: A differential gear mounting bracket is provided to prevent the cracking of an upper portion of a bracket due to the concentration of stress by dispersing the stress applied to the upper portion of the bracket. CONSTITUTION: A differential gear mounting bracket is formed in the rectangular cylinder having mounting holes(13). The differential gear mounting bracket is installed by welding with a welding parent metal(12). A reinforcing plate(15) is attached to a bracket member(11) and the parent metal while the upper portion of the bracket member is face-to-face contact to the parent metal. Since the welding range of the reinforcing plate is extended to the upper portion of side panels(14a,14b) of the bracket member, the combining strength of the upper portion of the bracket member is enhanced.

Description

차동 기어 마운팅 브라켓{A bracket for mounting a differential gear}A bracket for mounting a differential gear}

본 발명은 차동 기어 마운팅 브라켓에 관한 것이고, 보다 상세하게는 휠에 걸리는 토오크를 고려하여 주변 부품의 강성을 충분히 보강할 수 있는 차동 기어 마운팅 브라켓에 관한 것이다.The present invention relates to a differential gear mounting bracket, and more particularly to a differential gear mounting bracket that can sufficiently reinforce the rigidity of the peripheral components in consideration of the torque applied to the wheel.

일반적으로, 차동 장치(차동 기어)는 4륜 구동 시스템의 차량이 험로를 주행하거나 선회하거나 노면에 요철이 있는 경우에 좌우 바퀴에 자동적으로 회전차를 주는 것에 의하여, 4개의 바퀴에 구동력을 균등하게 배분하여, 차량의 원활한 주행이 이루어질 수 있도록 하는 것으로, 통상적으로 종감속 기어와 일체가 되어 액슬 하우징에 설치된다.In general, a differential device (differential gear) equally drives the four wheels by automatically giving the left and right wheels a wheel when the vehicle of the four-wheel drive system drives, turns, or has irregularities on the road surface. In order to distribute the vehicle, the vehicle may be smoothly driven, and is usually integrated with the longitudinal reduction gear and installed in the axle housing.

이러한 차동 장치는 통상적으로 차동 케이스와 차동 피니언 및 사이드 기어로 이루어져 있다. 차동 케이스는 종감속 장치의 링 기어에 볼트와 같은 고정 수단으로 고정되어 링 기어와 일체로 회전된다. 이 차동 케이스의 양측에는 좌우 바퀴와 연결된 좌우 차축이 관통, 지지되어 있으며, 차동 케이스의 중앙에는 차동 피니언이 설치되어 있다. 차축의 끝단에는 사이드 기어가 부착되어 있고, 이 사이드 기어는 차동 피니언과 맞물려 있다.Such a differential device typically consists of a differential case, a differential pinion and a side gear. The differential case is fixed to the ring gear of the reduction gear by means of fastening means such as bolts to rotate integrally with the ring gear. The left and right axles connected to the left and right wheels are penetrated and supported on both sides of the differential case, and a differential pinion is installed at the center of the differential case. A side gear is attached to the end of the axle, which is engaged with the differential pinion.

이러한 구성을 가지는 차량용 차동 장치는 구동축의 회전력이 종감속 장치를 통해 링 기어와 함께 회전되는 차동 케이스에 전달되면, 차동 케이스에 설치된 차동 피니언이 공전되고 이 차동 피니언의 공전에 의해 좌우 차축의 사이드 기어가 회전되어 차축이 구동된다. 이 때, 자동차가 평탄로를 직진하는 경우에는 좌우 바퀴의 회전 저항이 같으므로 좌우의 사이드 기어는 같은 회전수로 차동 피니언의 공정에 따라 회전되며, 만약 노면에 요철이 있거나 차량이 선회를 하게되면 좌우 바퀴에 걸리는 회전 저항이 달라지고 이에 따라 차동 피니언이 자전을 하게 되어 좌우의 사이드 기어는 각각 다른 회전수로 회전되어 좌우 바퀴의 회전수는 달라지게 된다.In a vehicle differential having such a configuration, when the rotational force of the drive shaft is transmitted to the differential case in which the rotational force of the drive shaft is rotated together with the ring gear, the differential pinion installed in the differential case revolves and the side gears of the left and right axles are rotated by the differential pinion. Is rotated to drive the axle. At this time, when the car goes straight on the flat road, the left and right wheels have the same rotational resistance, so the left and right side gears are rotated according to the process of the differential pinion at the same rotational speed, and if the road surface has irregularities or the vehicle turns The rotational resistance applied to the left and right wheels is changed, and accordingly the differential pinion rotates, so that the left and right side gears are rotated at different rotational speeds so that the rotational speed of the left and right wheels is changed.

도 1에는 차동 기어 마운팅 브라켓의 사시도가 개략적으로 도시되어 있다. 이러한 차동 기어 마운팅 브라켓은 통상 액슬 하우징의 3개소에 용접에 의하여 제공되며, 차동 기어는 마운팅을 통하여 차동 기어 마운팅 브라켓에 설치된다. 차동기어 마운팅 브라켓은 사각의 통체 형상을 가지는 브라켓 부재(11)의 한 쪽 측부가 액슬 하우징과 같은 용접 모재(12)에 서로 나란하게 용접되며, 브라켓 부재(11)들의 측면에 제공되는 판들은 차동 기어 마운팅이 설치되도록 각각 구멍(13)이 형성된다. 또한, 브라켓 부재(11)의 측판(14a,14b)들은 브라켓 부재(11)에 하중이 작용할 때 하중을 지지하는 기능을 한다.1 schematically shows a perspective view of a differential gear mounting bracket. Such differential gear mounting brackets are usually provided by welding to three places of the axle housing, and the differential gears are mounted to the differential gear mounting brackets through mounting. In the differential gear mounting bracket, one side of the bracket member 11 having a rectangular cylindrical shape is welded side by side to a welding base material 12 such as an axle housing, and the plates provided on the sides of the bracket members 11 Holes 13 are formed respectively so that the gear mounting is installed. In addition, the side plates 14a and 14b of the bracket member 11 function to support the load when the load is applied to the bracket member 11.

그러나, 상기된 바와 같은 종래의 차동 기어 마운팅 브라켓은 외팔보 구조를 가지기 때문에, 마운팅 브라켓에 작용하는 힘에 의하여 용접 모재(액슬 하우징)에 용접되는 상부 부분에 응력이 집중적으로 작용하고, 이러한 응력하에서 충분한 안전율이 고려되지 않는 경우에, 상부 부분의 용접부에 크랙이 발생되는 문제점이 있었다.However, since the conventional differential gear mounting bracket as described above has a cantilever structure, stress is concentrated on the upper portion welded to the welding base material (axle housing) by the force acting on the mounting bracket, and under such stress If the safety factor is not considered, there is a problem that cracks are generated in the welded portion of the upper portion.

따라서, 본 발명의 목적은 응력을 분산하여 응력의 집중에 의한 상부 부분에서의 크랙을 방지할 수 있는 구조를 가지는 차동 기어 마운팅 브라켓을 제공하는 데 있다.Accordingly, an object of the present invention is to provide a differential gear mounting bracket having a structure capable of dispersing stress to prevent cracking in the upper portion due to concentration of stress.

도 1은 종래의 차동 기어 마운팅 브라켓을 개략적으로 도시한 사시도.1 is a perspective view schematically showing a conventional differential gear mounting bracket.

도 2는 본 발명에 따른 자동 기어 마운팅 브라켓을 개략적으로 도시한 사시도.Figure 2 is a perspective view schematically showing an automatic gear mounting bracket according to the present invention.
