Since the exemplary embodiments of the present invention may be embodied in various different forms, one of ordinary skill in the art to which the present invention pertains may be described herein. It is not limited to the Example to make.

도 1(가)는 본 발명에 따른 휠 베어링 일체형 톤 휠이 장착된 액슬 구성도를 도시한 것인바, 본 발명은 현가 장치를 체결하는 너클(3)이 장착되고, 허브(2)쪽으로 압입 되어 차륜을 구동하는 드라이브 샤프트(1)부위로 톤 휠(7)이 구비되고, ECU가 차속을 인식하도록 상기 톤 휠(7)의 회전을 측정하는 휠 스피드 센서(4)가 상기 너클(3)부위를 이용해 체결되어진다.Figure 1 (a) shows the axle configuration is equipped with a wheel bearing integrated tone wheel according to the present invention, the present invention is equipped with a knuckle (3) for fastening the suspension device is pressed into the hub (2) A tone wheel 7 is provided at the drive shaft 1 driving the wheel, and a wheel speed sensor 4 measuring the rotation of the tone wheel 7 so that the ECU recognizes the vehicle speed is provided at the knuckle 3 area. It is fastened by using.

이를 위해, 상기 톤 휠(7)은 도 1(나)에 도시된 바와 같이, 허브(2)의 허브 압입 연장 단(2a)쪽으로 결합 된 너클(3)부위로 위치되는데, 즉 상기 허브 압입 연장 단(2a)과 이를 감싼 너클(3)사이로 구비된 베어링(5)에 결합되어져, 드라이브 샤프트(1)가 압입 된 허브(2)의 허브 압입 연장 단(2a)을 통해 베어링(5)이 회전될 때, 상기 베어링(5)과 함께 회전되어진다.To this end, the tone wheel 7 is located at the knuckle 3 portion coupled towards the hub indentation extension end 2a of the hub 2, ie the hub indentation extension, as shown in Fig. 1 (b). It is coupled to a bearing 5 provided between the end 2a and the knuckle 3 surrounding it, so that the bearing 5 rotates through the hub press-in extension end 2a of the hub 2 into which the drive shaft 1 is press-fitted. Is rotated together with the bearing (5).

이는, 상기 허브 압입 연장 단(2a)에 결합된 베어링(5)의 외부 노출 부위를 차단하는 씰(6,Seal)쪽으로 톤 휠(7)을 위치시키고, 너클(3)부위를 이용해 상기 톤 휠(7)의 회전을 감지하는 휠 스피드 센서(4)가 위치되어져, ECU쪽으로 측정 신호를 전송하게 된다.This places the tone wheel 7 towards the seal 6, which seals off the externally exposed portion of the bearing 5 coupled to the hub press-in extension end 2a, and uses the knuckle 3 portion to A wheel speed sensor 4 which detects the rotation of 7 is positioned to transmit the measurement signal to the ECU.

이러한, 상기 톤 휠(7)은 베어링(5)의 외부 노출 측면 부위를 막는 씰(6)의 외측 부위에 일체로 형성되는데, 즉 도 2에 도시된 바와 같이 베어링(5)의 외부 노출 측면 부위를 막도록 다수의 돌기를 형성한 씰(6)의 반대쪽으로 톤 휠(7)을 가류 시켜, 베어링(5)에 결합된 씰(6)과 톤 휠(7)을 일체형으로 제조하게 된다.This tone wheel 7 is integrally formed on the outer part of the seal 6 which blocks the outer exposed side part of the bearing 5, ie the outer exposed side part of the bearing 5 as shown in FIG. 2. The ton wheel 7 is vulcanized to the opposite side of the seal 6 having a plurality of protrusions formed therein, thereby manufacturing the seal 6 and the tone wheel 7 coupled to the bearing 5 in one piece.

이와 같은 상기 톤 휠(7)은 프레스 제조된 환형 고리 타입을 이루며, 슬롯(7c)이 등 간격으로 뚫려진 슬롯 바디 플랜지(7b)와, 상기 슬롯 바디 플랜지(7b)에서 절곡 되어져, 씰(6)과 일체화 되도록 씰(6)의 측면 쪽으로 가류 되어진 연결 플랜지(7a)로 단순하게 이루어지게 된다.The tone wheel 7 is a ring-shaped ring type manufactured by press, the slot 7c is bent from the slot body flange (7b) and the slot body flange (7b) is drilled at equal intervals, the seal 6 It is simply made of a connecting flange (7a) vulcanized toward the side of the seal (6) to be integrated.

여기서, 상기 톤 휠(7)은 슬롯 바디 플랜지(7b)에 뚫려진 슬롯(7c)을 휠 스피드 센서(4)가 감지할 수 있는 부위로 위치되어진다.In this case, the tone wheel 7 is positioned as a position where the wheel speed sensor 4 can detect the slot 7c drilled in the slot body flange 7b.

이와 같이 본 발명은 차륜으로 구동력을 전달하는 드라이브 샤프트(1)가 압 입 된 허브(2)의 허브 압입 연장 단(2a)쪽에서, 너클(3)과 함께 결합된 베어링(5)의 외부 노출 부위로 결합된 씰(6)과 톤 휠(7)이 일체를 이루도록 가류 됨에 따라, 휠 스피드 센서(4)가 차속을 측정하도록 감지하는 상기 톤 휠(7)의 체결 시 베어링(5)과 함께 간단히 조립될 수 있어, 압입이나 볼트 체결 때와 같은 조립 불편이 없음은 물론, 톤 휠(7)의 조립 공정도 축소할 수 있는 특징이 있게 된다.As such, the present invention provides an external exposed portion of the bearing 5 coupled with the knuckle 3 at the hub indentation extension end 2a of the hub 2 into which the drive shaft 1 which transmits the driving force to the wheel is pressed. As the seal 6 and the tone wheel 7 coupled together are vulcanized to form an integral part, the wheel speed sensor 4 simply together with the bearing 5 at the time of engagement of the tone wheel 7 sensing to measure the vehicle speed. Since it can be assembled, there is no assembly inconvenience, such as when pressing or bolting, as well as the assembly process of the tone wheel 7 can be reduced.

이를 위해, 본 발명의 톤 휠(7)은 도 2에 도시된 바와 같이, 베어링(5)의 외부 노출 측면 부위를 막아 주도록 베어링(5)에 결합된 씰(6)과 가류 되어져 일체로 형성되어진다.To this end, the tone wheel 7 of the present invention is vulcanized with the seal 6 coupled to the bearing 5 so as to block the outer exposed side portion of the bearing 5, as shown in FIG. Lose.

이러한 상기 톤 휠(7)은 회전 시 휠 스피드 센서(4)가 감지하는 슬롯(7c)을 등 간격으로 뚫은 슬롯 바디 플랜지(7b)를 형성하고, 상기 슬롯 바디 플랜지(7b)의 한쪽 부위로는 씰(6)과 일체화 되도록 씰(6)의 측면 쪽으로 가류 되는 연결 플랜지(7a)를 형성한 구조를 이루게 된다.The tone wheel 7 forms a slot body flange 7b which drills the slot 7c detected by the wheel speed sensor 4 at equal intervals during rotation, and the one side of the slot body flange 7b. The coupling flange 7a vulcanized toward the side of the seal 6 is formed to be integrated with the seal 6.

이와 같이 씰(6)의 측면 쪽으로 가류 되어져 씰(6)과 일체화 된 톤 휠(7)은 설치 시, 구동력을 전달하는 드라이브 샤프트(1)가 압입 된 허브(2)의 허브 압입 연장 단(2a)에 결합된 베어링(5)과 함께 조립되어진다.Thus, the tone wheel 7 vulcanized toward the side of the seal 6 and integrated with the seal 6 has a hub press-in extension end 2a of the hub 2 into which the drive shaft 1 which delivers the driving force is pressed during installation. It is assembled with the bearing (5) coupled to).

즉, 도 1(가),(나)에 도시된 바와 같이 허브(2)의 허브 압입 연장 단(2a)과 너클(3)사이로 씰(6)과 일체화 된 톤 휠(7)을 갖춘 베어링(5)을 결합하게 되면, 상기 베어링(5)의 외부 노출 측면이 씰(6)을 이용해 밀폐됨과 더불어, 씰(6)에 가류된 톤 휠(7)은 너클(3)에 설치 된 휠 스피드 센서(4)가 감지할 수 있는 영역으로 위치 될 수 있게 된다.That is, a bearing having a tone wheel 7 integrated with the seal 6 between the hub indentation extension end 2a of the hub 2 and the knuckle 3 as shown in FIGS. 5), the outer exposed side of the bearing (5) is sealed using the seal (6), and the tone wheel (7) vulcanized in the seal (6) is a wheel speed sensor installed in the knuckle (3) (4) can be positioned as a detectable area.

이와 같이 드라이브 샤프트(1)가 압입 되고 너클(3)이 결합된 허브(2)쪽에 너클(3)의 회전을 차단하도록 구비된 베어링(5)을 이용해 톤 휠(7)이 설치됨에 따라, 드라이브 샤프트(1)의 구동력으로 허브(2)가 회전할 때, 너클(3)이 정지된 상태에서 허브(2)와 함께 회전하는 베어링(5)을 통해 톤 휠(7)도 함께 회전되어진다.As the tone wheel 7 is installed using the bearing 5 provided to block the rotation of the knuckle 3 on the side of the hub 2 to which the drive shaft 1 is pressed and the knuckle 3 is coupled, the drive When the hub 2 is rotated by the driving force of the shaft 1, the tone wheel 7 is also rotated through the bearing 5 which rotates together with the hub 2 while the knuckle 3 is stopped.

이러한 톤 휠(7)의 회전은 톤 휠(7)의 위쪽에서 너클(3)부위로 설치된 휠 스피드 센서(4)를 통해 감지 즉, 휠 스피드 센서(4)가 톤 휠(7)의 슬롯 바디 플랜지(7b)에 등 간격으로 뚫려진 슬롯(7c)을 감지해 ECU로 신호를 전송하게 되면, 톤 휠(7)과 함께 회전하는 베어링(5)이 드라이브 샤프트(1)를 통해 회전하는 구동 륜의 회전 속도와 동일하므로, 휠 스피드 센서(4)를 통한 차속을 측정할 수 있게 된다.The rotation of the tone wheel 7 is detected by the wheel speed sensor 4 installed on the knuckle 3 portion above the tone wheel 7, that is, the wheel speed sensor 4 is inserted into the slot body of the tone wheel 7. When the slot 7c, which is drilled at equal intervals in the flange 7b, is detected and transmitted to the ECU, the drive wheel in which the bearing 5 rotating together with the tone wheel 7 rotates through the drive shaft 1 Since it is the same as the rotational speed of, the vehicle speed through the wheel speed sensor 4 can be measured.
