Abstract

The present invention relates to a coupling structure for a bearing and a constant velocity joint that removes a stem from an outer race of the constant velocity joint, thus reducing the weight of the outer race. Accordingly, the driving efficiency of the wheel is improved through the reduction of the weight of the wheel, and further, manufacturing costs are also reduced since material costs are reduced. Particularly, the outer race and a hub are serration-coupled and fixed by means of bolts, thus making the exchanging and repairing of the wheel bearing easier, and the outer race becomes short and thick, thus greatly increasing the load strength to prevent the serrations from being damaged due to bending load. The coupling structure of the present invention includes: a constant velocity joint transmitting a driving force of a vehicle power unit to a wheel; a wheel bearing coupled to the constant velocity joint to rotate; an outer race formed on one side surface of the constant velocity joint to be open to insert the wheel bearing and having a female serration formed in the inner circumference into which the wheel bearing is inserted; a hub having a male serration formed thereon to be engaged with the female serration of the outer race; caulking pins whose lower portions fixedly inserted into a coupling groove formed on the outer circumference of a portion where the outer race and the hub are coupled to each other; and a sealing cap located on one side of the wheel bearing to prevent the introduction of foreign matters.

휠 베어링의 허브와 아웃트레이스의 코킹 결합구조{Combining structure using cocking for wheel bearing and outer race of constant velocity joint}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wheel-

본 발명은 휠 베어링의 허브와 아웃트레이스의 코킹 결합구조에 관한 것으로서, 보다 상세하게는 등속조인트의 아웃트레이스와 휠베어링 허브의 형상을 변경하고, 이들을 체결하기 적합하게 형성된 별도의 체결수단을 구비함으로써 결합 강도 및 전동 성능을 그대로 유지하면서 전체 중량을 감소하고 결합방법을 간편하게 한 휠 베어링의 허브와 아웃트레이스의 코킹 결합구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cogging coupling structure of a hub and an outrace of a wheel bearing, and more particularly, To a cogging joint structure of a hub and an outrace of a wheel bearing, which reduces the total weight and simplifies the joining method while maintaining the joining strength and the transmission performance.

일반적으로 조인트는 회전축의 각도가 서로 다른 회전축에 회전동력(토크)을 전달하기 위한 것으로서, 동력전달 각도가 작은 추진축의 경우에는 후크 조인트, 플렉시블 조인트 등이 사용되고, 동력전달 각도가 큰 전륜 구동차의 구동축의 경우에는 등속 조인트가 사용된다. Generally, a joint is for transmitting rotational power (torque) to a rotation shaft having different angles of rotation axis. In the case of a propulsion shaft having a small power transmission angle, a hook joint, a flexible joint or the like is used. A constant velocity joint is used.

상기한 등속조인트(constant velocity joint)는 차량의 종감속장치에 연결된 구동차축에 설치되어 차륜에 동력을 전달하는 장치로서, 구동축과 피동축 사이에 회전속도나 토크의 변동을 일으키지 않으면서 큰 각도에서도 동력을 일정하게 전달하는 구조이다.The constant velocity joint described above is a device that is installed on a drive axle connected to a longitudinal decelerating device of a vehicle and transmits power to the wheel. The constant velocity joint does not cause a change in rotational speed or torque between a drive shaft and a driven shaft, It is a structure that transmits power constantly.

상기한 등속 조인트는 구동축과 피동축의 교차각이 큰 경우에도 등속으로 원활하게 동력을 전달할 수 있기 때문에 독립 현가 방식의 전륜 구동차의 액슬축에 주로 사용되며, 샤프트를 중심으로 변속기측(인보드측)은 트라이포드식 등속 조인트나 슬라이드형 볼타입 등속 조인트로 이루어지고, 샤프트를 중심으로 휠측(아웃보드측)은 고정형 볼타입 등속 조인트로 이루어진다. Since the constant velocity joint can smoothly transmit power at a constant speed even when the angle of intersection between the drive shaft and the driven shaft is large, it is mainly used for the axle shaft of the independent suspension type front wheel drive vehicle, and the transmission side (inboard side) Type constant velocity joint or a slide type ball type constant velocity joint, and the wheel side (outboard side) is formed of a fixed ball type constant velocity joint around the shaft.

도 1은 종래의 휠 베어링의 허브와 아웃트레이스의 코킹 결합구조를 나타낸 단면도이다.1 is a cross-sectional view showing a caulking structure of a hub and an outer trace of a conventional wheel bearing.

도 1에 도시된 바와 같이, 휠 베어링의 허브와 아웃트레이스의 코킹 결합구조는 차량 동력장치의 구동력을 차륜에 전달하는 등속조인트(10)와, 차륜에 결합되는 휠베어링(20)으로 이루어져 있다.As shown in Fig. 1, the cogging coupling structure of the hub and the outrace of the wheel bearing comprises a constant velocity joint 10 for transmitting the driving force of the vehicle power train to the wheel, and a wheel bearing 20 coupled to the wheel.

여기에서, 휠베어링(20)은 다시 외륜체(21)와 허브(22)로 구성되는바, 외륜체(21)는 차체에 지지되어 고정되며, 허브(22)는 외륜체(21)의 내주면에 전동체(23)를 사이에 두고 결합된다. 이때, 허브(22)는 외측단이 차륜에 결합되며, 전동체(23)는 일반적으로 차체의 하중을 견디면서 원활하게 회전하도록 복열로 장착된다. Here, the wheel bearing 20 is constituted by the outer ring body 21 and the hub 22, and the outer ring body 21 is supported and fixed to the vehicle body. The hub 22 is fixed to the inner peripheral surface of the outer ring body 21 And is coupled with the rolling member 23 therebetween. At this time, the outer end of the hub 22 is coupled to the wheel, and the rolling member 23 is mounted in a double row so as to smoothly rotate while bearing the load of the vehicle body.

또, 허브(22)의 외면 일측에는 별도의 내륜체(24)가 결합되어 외륜체(21)와 허브(22) 외주면 사이의 전동체(23)에 가해지는 예압을 조절하도록 되어 있다.A separate inner ring member 24 is coupled to one side of the outer surface of the hub 22 so as to adjust a preload applied to the rolling member 23 between the outer ring member 21 and the outer peripheral surface of the hub 22.

한편, 허브(22)와 결합되는 아웃트레이스(11)는 차륜측 중앙에 허브(22)의 중심부를 관통하는 스템(12)이 길게 연장 형성되어 있으며, 이 스템(12)의 외측 단부에 가공된 나사부(13)가 너트(30)에 결합됨으로써 허브(22)와 아웃트레이스(11)를 체결하도록 되어 있다. The outtrace 11 coupled with the hub 22 has a stem 12 extending through the center of the hub 22 at the center of the wheel and extending to the outer end of the stem 12, The threaded portion 13 is engaged with the nut 30 so as to fasten the hub 22 and the outtrace 11.

그리고 허브(22)와 스템(12)은 각각 내주면과 외주면에 암형 세레이션과 수형 세레이션이 가공되어 등속조인트(10)의 회전력을 손실 없이 허브(22)로 전달하도록 되어 있다. The hub 22 and the stem 12 are formed with female serration and male serration on the inner circumferential surface and the outer circumferential surface, respectively, so that the rotational force of the constant velocity joint 10 is transmitted to the hub 22 without loss.

그런데 위와 같은 종래의 휠베어링과 등속조인트 체결구조는 허브(22)와 아웃트레이스(11)의 결합이 아웃트레이스 스템(12)에 의해서만 이루어지므로, 결합 강도를 유지하기 위해 스템(12)을 일정 길이 이상으로 제작하여야 한다.However, in the above conventional wheel bearing and constant velocity joint fastening structure, since the coupling between the hub 22 and the outtrace 11 is made only by the outtrace stem 12, Or more.

따라서 아웃트레이스(11)의 중량이 증가하며, 제작 비용이 상승하고, 증가한 중량만큼 구동효율이 저하되는 문제점이 있었다.Therefore, there is a problem that the weight of the outtrace 11 increases, the manufacturing cost rises, and the driving efficiency decreases by an increased weight.

본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 휠베어링의 허브와 결합되는 등속조인트의 아웃트레이스 스템을 생략함으로써, 긴 아웃트레이스 스템으로 인한 등속조인트의 중량화를 방지하면서도, 휠베어링과 등속조인트 간의 결합 강도나 전동 성능은 그대로 유지할 수 있도록 하는 데 그 목적이 있다.SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and omit the out-traced stem of the constant-velocity joint, which is coupled with the hub of the wheel bearing, The purpose of the invention is to maintain the coupling strength and electric performance between the wheel bearing and the constant velocity joint.

상기한 목적을 달성하기 위한 수단으로서 본 발명의 구성은, 차량 동력장치의 구동력을 차륜에 전달하는 등속조인트와. 상기 등속조인트와 결합되어 회전하는 휠베어링과, 상기 등속조인트의 일측면에 상기 휠베어링이 삽입하도록 개방되어 있으며 상기 휠베어링이 삽입되는 내주면에 암형 세레이션이 형성되는 아웃트레이스와, 상기 아웃트레이스의 암형 세레이션에 맞물려 결합되는 수형 세레이션이 형성되는 허브와, 상기 아웃트레이스와 상기 허브가 결합되는 외주면에 결합홈이 형성되며 결합홈에 삽입시킨 후 코킹시켜서 고정하는 코킹핀과, 상기 휠베어링의 일측면에 이물질의 유입을 방지하는 씰링 방지용 캡을 포함하여 이루어지면 바람직하다.As a means for achieving the above object, the present invention provides a constant velocity joint for transmitting a driving force of a vehicle power unit to a wheel. An outer trace which is opened to insert the wheel bearing into one side of the constant velocity joint and in which a female serration is formed on an inner circumferential surface where the wheel bearing is inserted; A caulking pin having a coupling groove formed on an outer circumferential surface of the outer race and the hub to be engaged with each other and inserted into the coupling groove and caulked to fix the wheel serration, And a sealing cap for preventing foreign matter from entering the one side surface.

본 발명의 구성은, 상기 허브의 수형 세레이션의 외주면에는 상기 고정장치가 결합되도록 다수의 홀이 형성되면 바람직하다.In the configuration of the present invention, it is preferable that a plurality of holes are formed on the outer circumferential surface of the male serration of the hub so that the fixing device is engaged.

본 발명의 구성은, 상기 허브의 수형 세레이션의 외주면에는 상기 고정장치가 결합되도록 다수의 홀이 형성되면 바람직하다.In the configuration of the present invention, it is preferable that a plurality of holes are formed on the outer circumferential surface of the male serration of the hub so that the fixing device is engaged.

본 발명의 구성은, 상기 코킹핀에 있어서 코킹핀의 좌.우측으로 테이퍼가 형성되면 바람직하다.The constitution of the present invention is preferable if a taper is formed on the left and right sides of the caulking pin in the caulking pin.

본 발명의 휠 베어링의 허브와 아웃트레이스의 코킹 결합구조에 의하면, 등속조인트의 아웃트레이스에서 스템이 제거되므로, 아웃트레이스의 중량을 줄일 수 있게 된다. 따라서, 감소된 중량만큼 차륜의 구동효율을 증대시킬 수 있게 될 뿐 아니라, 재료비 감소로부터 제작 비용을 절감을 기대할 수 있게 된다. 특히 아웃트레이스와 허부를 세레이션 결합후 볼트로 고정함으로써 휠베어링의 교체 수리가 보다 용이해지며 아웃트레이스가 짧고 굵어 하중에 대한 강성을 크게 증가시켜 굽힘하중에 의한 세레이션의 손상을 방지할 수 있는 효과가 있다.According to the present invention, since the stem is removed from the out-traces of the constant-velocity joint, the weight of the out-traces can be reduced. Therefore, it is possible not only to increase the driving efficiency of the wheel by the reduced weight, but also to reduce the manufacturing cost from the reduction of the material cost. Especially, it is possible to repair the replacement of wheel bearings by fixing bolts to outraces and selves after serration joining, and it is possible to prevent the damage of serration due to bending load by greatly increasing the rigidity against heavy load It is effective.
