본 발명은 트레일링암 마운팅 위치 자동조절장치에 관한 것으로, 더욱 상세하게는 차량의 주행상황에 따라 트레일링암의 차체 마운팅 위치를 자동으로 조절함으로써, 승차감 및 조안성 등을 향상시킬 수 있는 차량의 트레일링암 마운팅 위치 자동조절장치에 관한 것이다.The present invention relates to a trailing arm mounting position automatic adjustment device, and more particularly, by automatically adjusting the body mounting position of the trailing arm in accordance with the driving situation of the vehicle, the trailing arm of the vehicle that can improve ride comfort and stability It relates to a mounting position automatic adjustment device.

일반적으로 차량의 서스펜션 장치는 차량의 주행중 노면으로부터 지속적으로 발생되는 진동 및 충격이 휠 및 차축(Axle)을 통해 프레임에 전달되는 것을 방지하는 기능을 한다.In general, the suspension device of a vehicle serves to prevent vibration and shock continuously generated from the road surface of the vehicle while being transmitted to the frame through the wheel and the axle.

또한, 서스펜션 장치는 탑승자의 승차감을 향상시킴과 동시에 적재된 수화물의 손상을 방지하고, 무리한 충격에 의해 차체가 손상되는 것을 방지하는 것이며, 휠의 불규칙한 진동을 억제하여 주행의 안전을 도모하는 장치이다.In addition, the suspension device improves the ride comfort of the occupant, prevents damage to the loaded luggage, prevents damage to the vehicle body due to excessive shock, and suppresses irregular vibrations of the wheel to promote driving safety. .

상기와 같은 서스펜션 장치는 구조적으로 크게 일체식 서스펜션 장치와 독립식 서스펜션 장치로 구분된다. 여기서, 독립식 서스펜션 장치는 좌우 휠을 하나의 차축에 연결하지 않고 서로 다른 휠에 관계없이 움직일 수 있도록 구성된 것이다.Such a suspension device is largely divided into an integrated suspension device and an independent suspension device. Here, the independent suspension device is configured to be able to move regardless of different wheels without connecting the left and right wheels to one axle.

따라서, 승용차의 프런트 휠에 가장 많이 사용되며, 또한 소형 트럭의 프런트 휠이나 승용차의 리어 휠에도 상당히 많이 사용되고 있다.Therefore, it is most often used for front wheels of passenger cars, and is also used for front wheels of light trucks and rear wheels of passenger cars.

도 1은 일반적인 자동차의 후륜 서스펜션을 나타낸 사시도이고, 도 2a 및 도 2b는 종래의 트레일링암 차체 마운팅 위치를 개략적으로 나타낸 측면도이다.1 is a perspective view showing a rear wheel suspension of a typical vehicle, Figures 2a and 2b is a side view schematically showing a conventional trailing arm body mounting position.

도 1의 도시와 같이 리어 서스펜션의 일종인 CTBA(Coupled Torsion Beam Axle) 서스펜션 장치(100)는 양단의 트레일링암(Trailing Arm)(110)과 이를 연결하여 비틀림을 받는 토션빔(Torsion Beam)(120)이 용접에 의해 결합되어 있으며, 트레일링암(110)의 일단에는 휠(130)이 설치되고 다른 일단에는 차체와의 고정을 위한 마운팅 브라켓(140)이 설치된 구조이다.As shown in FIG. 1, a CTBA (Coupled Torsion Beam Axle) suspension device 100, which is a kind of rear suspension, is connected to a trailing arm 110 at both ends thereof and receives a torsion beam 120. ) Is coupled by welding, and one end of the trailing arm 110 is provided with a wheel 130, and the other end has a mounting bracket 140 for fixing to the vehicle body.

이러한, CTBA 서스펜션은 간단한 구조와 저렴하다는 장점이 있지만, 중앙에 위치한 토션빔(120)의 토션 변형 특성으로 인해 휠(130)의 변형이 이루어지기 때문에 주로 소형차의 후륜에 주로 사용되고 있으며, CTBA 서스펜션의 거동은 토션빔(120)의 위치와, 두께와, 단면형상 및, 트레일링암(110) 차체 마운팅 위치와 휠 중심 위치의 "Z"축상 상대위치에 의해 롤 스티어(Roll Steer) 특성과, 안티 리프트(Anti-Lift) 특성 및, 승차감 특성이 다음과 같이 변경된다.The CTBA suspension has the advantages of a simple structure and low cost, but is mainly used in the rear wheel of a compact car because the deformation of the wheel 130 is made due to the torsional deformation characteristic of the torsion beam 120 located at the center. The behavior is based on the position and thickness of the torsion beam 120, the roll steer characteristics and the anti-lift by the relative position on the "Z" axis of the trailing arm 110 body mounting position and the wheel center position. (Anti-Lift) characteristics and ride comfort characteristics are changed as follows.

즉, 도 2a의 도시와 같이 트레일링암(110) 차체 마운팅 위치가 휠(130) 중심보다 높은 경우에는 안티 리프트가 좋아지고 충돌시 트레일링암(110)이 후방으로 밀려 승차감은 좋지만, 롤링시 높이차 및 좌우 휠의 상대운동(선회외륜-Bump, 선회내륜-Rebound)에 의해 오버스티어 경향을 보이게 됨으로써, 직진 주행시에는 주행성능이 향상되지만, 선회시에는 주행성능이 저하되는 단점이 있다.That is, as illustrated in FIG. 2A, when the body mounting position of the trailing arm 110 is higher than the center of the wheel 130, the anti-lift is improved and the trailing arm 110 is pushed to the rear during a collision, so that the riding comfort is good. And since the oversteering tendency is shown by the relative movement of the left and right wheels (spinning outer ring-Bump, turning inner ring-Rebound), the driving performance is improved when driving straight, but the driving performance is lowered when turning.

반면, 도 2b의 도시와 같이 트레일링암(110) 차체 마운팅 위치가 휠(130) 중심보다 낮은 경우에는 롤링시 안티 리프트가 나빠지고 충돌시 트레일링암(110)이 앞으로 이동하여 승차감은 나빠지나, 롤시 높이차 및 좌우 휠의 상대운동(선회외륜-Bump, 선회내륜-Rebound)에 의해 언더스티어 경향을 보이게 됨으로써, 선회시에는 주행성능이 향상되지만, 직진 주행시에는 주행성능이 저하되는 단점이 있다.On the other hand, when the body mounting position of the trailing arm 110 is lower than the center of the wheel 130 as shown in FIG. 2B, the anti-lift lifts during rolling and the trailing arm 110 moves forward during a collision, resulting in poor riding comfort. By showing the understeer tendency by the relative difference between the height difference and the left and right wheels (spinning outer ring-bump, turning inner ring-rebound), the driving performance is improved during the turning, but the driving performance is lowered when driving straight.

따라서, CTBA 서스펜션 장치는 구조적인 한계로 롤 언더 스티어 성능과 안티 리프트 및 승차감 특성의 동시 육성이 용이하지 못하다는 문제점이 있게 된다.Therefore, the CTBA suspension device is a structural limitation, there is a problem that the simultaneous growth of the roll understeer performance and anti-lift and ride comfort characteristics is not easy.

따라서, 본 발명은 전술한 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 차량의 주행상황에 따라 트레일링암 마운팅 위치를 자동으로 조절함으로써, 승차감 및 조안성 등을 향상시킬 수 있는 트레일링암 마운팅 위치 자동조절장치를 제공함에 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention by automatically adjusting the trailing arm mounting position according to the driving situation of the vehicle, it is possible to improve the riding comfort and stability To provide a trailing arm mounting position automatic adjustment device.

이러한, 본 발명은 일단에 휠이 설치된 트레일링암; 상기 트레일링암의 다른 일단이 제 1체결구에 의해 회동 가능한 구조로 결합되어 차체에 고정 설치되며, 상기 제 1체결구의 주변에는 소정의 슬롯공이 형성된 마운팅 브라켓; 상기 마운팅 브라켓에 형성된 슬롯공을 통해 트레일링암과 결합되는 제 2체결구; 상기 제 2체결구의 선단에 압입 고정되는 소켓; 상기 트레일링암에 고정 설치되어 ECU에 의해 구동되는 모터 및; 상기 모터와 소켓 사이에 설치되어 차량의 주행 상황에 따라 제 2체결구가 슬롯공을 따라 안내 이동되도록 하는 동력전달수단을 포함하여 구성되는 것 을 특징으로 한다.Such, the present invention is a trailing arm installed wheel at one end; A mounting bracket coupled to the other end of the trailing arm in a rotatable structure by a first fastener and fixedly mounted to the vehicle body, and having a predetermined slot hole formed around the first fastener; A second fastening tool coupled to the trailing arm through a slot hole formed in the mounting bracket; A socket press-fitted to the tip of the second fastener; A motor fixedly mounted to the trailing arm and driven by an ECU; Is installed between the motor and the socket is characterized in that it comprises a power transmission means for guiding movement along the slot hole according to the driving situation of the vehicle.

이하, 본 발명이 속하는 기술분야에서 통상의 지식을 가진자가 본 발명을 용이하게 실시할 수 있을 정도로 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art can easily implement the present invention.

도 3은 본 발명의 구조를 나타낸 사시도이고, 도 4는 도 3의 "A"부 상세도이며, 도 5는 마운팅 브라켓의 정면도이고, 도 6a 및 도 6b는 본 발명의 작동상태도이다.Figure 3 is a perspective view showing the structure of the present invention, Figure 4 is a detailed view "A" of Figure 3, Figure 5 is a front view of the mounting bracket, Figures 6a and 6b is an operating state diagram of the present invention.

도 3 내지 도 6의 도시와 같이 본 발명은 차체 마운팅 브라켓(20)에 설치되는 트레일링암(10)의 위치를 자동으로 조절할 수 있는 마운팅 위치 자동조절장치를 포함하여 구성된다.As shown in FIGS. 3 to 6, the present invention includes a mounting position automatic adjustment device capable of automatically adjusting the position of the trailing arm 10 installed on the vehicle body mounting bracket 20.

트레일링암(10)의 일단이 결합되는 마운팅 브라켓(20)의 전면에는 소정의 형태로 슬롯공(21)이 형성되고, 그 하단에는 원형의 체결공(22)이 형성되어, 체결공(22)과 트레일링암(10)을 관통하는 제 1체결구(30)에 의해 트레일링암(10)이 마운팅 브라켓(20)으로부터 회동 가능하게 결합된다.A slot hole 21 is formed in a predetermined shape on a front surface of the mounting bracket 20 to which one end of the trailing arm 10 is coupled, and a circular fastening hole 22 is formed at a lower end thereof, and the fastening hole 22 is formed. And the trailing arm 10 are rotatably coupled from the mounting bracket 20 by the first fastener 30 penetrating the trailing arm 10.

이때, 슬롯공(21)은 마운팅 브라켓(20)으로부터 회동하는 트레일링암(10)의 회전축과 동일한 중심을 가지는 장공으로 형성된다.At this time, the slot hole 21 is formed of a long hole having the same center as the rotation axis of the trailing arm 10 to rotate from the mounting bracket (20).

한편, 마운팅 브라켓(20)에 형성된 슬롯공(21)을 통해 제 2체결구(40)가 끼워져 트레일링암(10)의 다른 일단을 결합하도록 한다.On the other hand, the second fastener 40 is fitted through the slot hole 21 formed in the mounting bracket 20 to couple the other end of the trailing arm 10.

이때, 제 2체결구(40)는 후술될 모터(60)의 구동력에 의한 회전동작이 용이 하게 하기 위하여 캠볼트로 구성되는 것이 바람직하다.At this time, the second fastener 40 is preferably configured as a cam bolt to facilitate the rotation operation by the driving force of the motor 60 to be described later.

이러한, 제 2체결구(40)의 상단에는 소켓(50)이 압입 고정되어 있으며, 트레일링암(10)에는 ECU(70)에 의해 구동하는 모터(60)가 고정 설치되어 주행 상황에 따라 모터(60)가 구동되면서 소정의 동력전달수단(80)이 모터(60)의 구동축(61)과 소켓(50) 사이를 연결하여 제 2체결구(40)를 회동시킴에 따라 제 2체결구(40)가 슬롯공(21)을 따라 안내되어 이동되도록 구성되어 있다.The socket 50 is press-fitted and fixed to the upper end of the second fastening hole 40, and the motor 60 driven by the ECU 70 is fixedly installed to the trailing arm 10 so that the motor ( As the 60 is driven, the predetermined power transmission means 80 connects between the drive shaft 61 of the motor 60 and the socket 50 to rotate the second fastener 40 so as to rotate the second fastener 40. ) Is configured to be guided and moved along the slot hole (21).

이때, 동력전달수단(80)으로는 모터(60)의 구동축(61)과 소켓(50) 사이에 설치되는 다수의 연결샤프트(81)와, 다수의 연결샤프트(81) 간을 연결하는 유니버셜조인트(82)로 구성된다.At this time, as the power transmission means 80 a plurality of connection shafts 81 installed between the drive shaft 61 and the socket 50 of the motor 60, and a universal joint connecting the plurality of connection shafts 81 It consists of 82.

따라서, 모터(60)의 구동력은 구동축(61)과, 유니버셜조인트(82) 및 연결샤프트(81) 순으로 소켓(50)에 전달됨으로써, 소켓(50)이 슬롯공(21)을 따라 이동 가능하게 된다.Therefore, the driving force of the motor 60 is transmitted to the socket 50 in the order of the drive shaft 61, the universal joint 82 and the connecting shaft 81, so that the socket 50 can move along the slot hole 21. Done.

이와 같이 구성되는 본 발명의 작동상태를 첨부된 도 6a 및 도 6b를 참조하여 설명하면 다음과 같다.Referring to Figures 6a and 6b attached to the operating state of the present invention configured as described above are as follows.

먼저, 차량이 직진 주행하고 있는 경우에는 도 6a의 도시와 같이 마운팅 브라켓(20)의 슬롯공(21)에 결합된 제 2체결구(40)가 슬롯공(21)의 상단에 위치되어 트레일링암(10) 차체 마운팅 위치는 휠(90)의 중심보다 높은 상태를 유지한다.First, when the vehicle is traveling straight, as shown in FIG. 6A, the second fastening hole 40 coupled to the slot hole 21 of the mounting bracket 20 is positioned at the upper end of the slot hole 21, and thus the trailing arm. (10) The body mounting position remains higher than the center of the wheel 90.

한편, 차량이 직진 주행하는 도중 커브 길 또는 갈래 길 등에서 방향을 전환하기 위하여 핸들을 돌리면, ECU(70)는 차량의 차속과 조향각의 신호를 읽고 차량의 상황을 판단하여 모터(60)를 구동시키고, 모터(60)의 구동력은 유니버셜조인 트(82)와 연결샤프트(81)로 구성된 동력전달수단(80)을 통해 소켓(50)에 전달되며, 소켓(50)은 다시 제 2체결구(40)에 동력을 전달하기 때문에 제 2체결구(40)는 제 1체결구(30)를 중심으로 슬롯공(21)을 따라 하단측으로 이동하게 되어 결국 트레일링암(10)의 차체 마운팅 위치는 휠(90)의 중심보다 낮은 상태가 된다.On the other hand, when the steering wheel is turned to change the direction on a curve road or a fork road while the vehicle is traveling straight, the ECU 70 reads signals of the vehicle speed and steering angle of the vehicle, determines the state of the vehicle, and drives the motor 60. The driving force of the motor 60 is transmitted to the socket 50 through the power transmission means 80 composed of the universal joint 82 and the connecting shaft 81, and the socket 50 is again connected to the second fastener 40. Since the second fastener 40 is moved to the lower side along the slot hole 21 around the first fastener 30 so that the body mounting position of the trailing arm 10 is the wheel (). The state becomes lower than the center of 90).

따라서, 상기와 같이 차량의 주행 상황에 따라 트레일링암 마운팅 위치가 자동으로 조절되기 때문에 차량의 주행 상황에 맞는 성능(승차감, 조안성)을 구현할 수 있게 된다.Therefore, since the trailing arm mounting position is automatically adjusted according to the driving situation of the vehicle as described above, performance (ride comfort and stability) suitable for the driving situation of the vehicle can be realized.

이상 본 고안을 바람직한 실시예를 사용하여 상세히 설명하였으나, 본 고안의 범위는 특정 실시예에 한정되는 것은 아니며, 첨부된 실용신안청구범위에 의하여 해석되어야 할 것이다. 또한, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 고안의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 이해하여야 할 것이다.Although the present invention has been described in detail using the preferred embodiments, the scope of the present invention is not limited to the specific embodiments, it should be interpreted by the appended utility model claims. In addition, those of ordinary skill in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

상술한 바와 같이 본 발명은 차량의 주행 상황에 따라 모터가 구동하여 구동축을 회전시키면 차체 마운팅 브라켓에 형성된 슬롯공을 따라 제 2체결부재가 이동하면서 트레일링암의 차체 마운팅 위치를 자동으로 조절하기 때문에 고가의 액츄에이터 및 부품을 사용할 필요가 없고, 또 그 구조가 간단하여 협소한 공간 내에서 설치가 가능하다는 장점이 있다.As described above, according to the present invention, when the motor is driven and the driving shaft is rotated according to the driving condition of the vehicle, the second fastening member is moved along the slot hole formed in the vehicle mounting bracket, and thus the vehicle mounting position of the trailing arm is automatically adjusted.
