이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 선회안정성 향상장치를 설명하기 위한 개략적인 개념도로서, 본 발명에 따른 선회안정성 향상장치는 코너링 주행(선회 주행)시 비구동축에 장착된 바퀴중 선회 중심을 기준으로 하여 내륜측 바퀴의 회전속도를 일정속도로 감속시킴으로써 차량의 주행안정성과 조향안정성을 동시에 향상시키는 역할을 수행하게 된다.1 is a schematic conceptual diagram for explaining a turning stability improving apparatus according to the present invention, the turning stability improving apparatus according to the present invention is the inner ring on the basis of the turning center of the wheels mounted on the non-driven shaft during cornering driving (turning driving) By decelerating the rotational speed of the side wheels at a constant speed, the vehicle's driving stability and steering stability are simultaneously improved.
즉, 본 발명에 따른 선회안정성 향상장치는 도 1 내지 도 3에 도시된 바와 같이 크게 비구동축(1) 바퀴(2;I/W,O/W)의 휠(도시않됨)에 각각 장착되는 디스크용 주차브레이크앗세이(10)와, 일단이 상기 디스크용 주차브레이크앗세이(10)를 작동시키기 위해 구성되는 브레이크슈 레버(13)와 플렉시블 와이어(21)를 통해 연결되면서 타단이 상기 비구동축(1)상에 접합되어 고정되도록 설치되어져 선회 중심을 기준으로 내륜측 바퀴(2;I/W)에 장착된 디스크용 주차브레이크앗세이(10)에 제동력을 발생시키면서 회전속도를 감속시키도록 하는 제동조작수단(30)으로 구성된다.That is, the swing stability improving apparatus according to the present invention is a disk mounted on the wheel (not shown) of the wheel (2; I / W, O / W) of the non-drive shaft (1) largely, as shown in Figures 1 to 3 Parking brake assembly 10 and one end is connected to the brake shoe lever 13 and the flexible wire 21 configured to operate the disk parking brake assembly 10 while the other end of the non-drive shaft ( 1) Braking which is installed to be fixed and bonded to the brake to reduce the rotational speed while generating a braking force to the disk parking brake assembly 10 mounted on the inner wheel side wheels 2 (I / W) based on the pivot center. It consists of the operation means 30.
여기서, 상기한 디스크용 주차브레이크앗세이(10)는 기존 승용차의 구동축인 뒷바퀴의 휠에 장착되는 것과 동일한 구성을 가지는 것으로써, 본 발명에서는 비구동축(1)인 앞바퀴(2)의 휠에 각각 장착되며, 개략적인 작동과정은 도 2와 도 3을 참조로 설명한 다음과 같다.Here, the disk parking brake assembly 10 for the disc has the same configuration as that mounted on the wheel of the rear wheel which is the drive shaft of the existing passenger car, in the present invention, respectively, on the wheels of the front wheel (2) which is the non-drive shaft (1) Mounted, the schematic operation process is as follows with reference to Figures 2 and 3.
즉, 운전자의 브레이크페달을 조작에 따라 브레이크오일에 유압이 발생되면, 이 유압에 의해 캘리퍼(11)내에 구비된 브레이크실린더의 피스톤이 브레이크디스크(12)쪽으로 압출되며, 이에 따라 브레이크패드가 차륜과 일체로 회전되는 브레이크디스크(12)에 압입되면서 마찰력에 의한 제동력을 발생시킴으로써 회전되는 차륜은 일정속도로 감속되게 된다.That is, when hydraulic pressure is generated in the brake oil according to the operation of the driver's brake pedal, the piston of the brake cylinder provided in the caliper 11 is extruded toward the brake disc 12 by the hydraulic pressure. The wheel to be rotated is decelerated at a constant speed by generating a braking force by friction while being pressed into the brake disc 12 which is integrally rotated.
또한, 본 발명에 따른 제동조작수단(30)의 작동에 따라 플렉시블 와이어(21)가 도시된 화살표 방향으로 당겨지게 되면, 브레이크슈 레버(13)의 힌지회동에 의해 브레이크슈(14)가 확장되게 되고, 이에 따라 브레이크슈(14)와 결합된 라이닝(15)이 드럼의 역할을 하는 디스크윗부분(16)의 안쪽면에 압착되면서 마찰력에 의한 제동력을 발생시키게 됨으로써 브레이크디스크(12)의 제동이 이루어지게 된다.In addition, when the flexible wire 21 is pulled in the direction of the arrow shown in accordance with the operation of the braking operation means 30 according to the present invention, the brake shoe 14 is extended by the hinge rotation of the brake shoe lever 13. Accordingly, the lining 15 coupled with the brake shoe 14 is pressed against the inner surface of the upper disk 16 serving as a drum to generate a braking force by the friction force, thereby making the brake disc 12 brake. You lose.
한편, 디스크용 주차브레이크앗세이(10)와 더불어 본 발명에 따라 선회안정성 향상장치를 구성하는 상기 제동조작수단(30)은 도 1 내지 도 3에 도시된 바와 같이, 상기 플렉시블 와이어(21)와 결합되는 와이어브라켓트부재(31)와, 상기 비구동축(1)상에 용접결합을 통해 고정되도록 설치되는 비구동축브라켓트부재(32)와, 상기 와이어브라켓트부재(31)와 비구동축브라켓트부재(32)를 연결하는 압축스프링부재(33)로 구성된다.On the other hand, the braking operation means 30 constituting the turning stability improving device in accordance with the present invention in addition to the parking brake assembly 10 for the disk, as shown in Figures 1 to 3, and the flexible wire 21 The wire bracket member 31 to be coupled, the non-drive shaft bracket member 32 which is installed to be fixed on the non-drive shaft 1 by welding coupling, the wire bracket member 31 and the non-drive shaft bracket member 32 Compression spring member 33 for connecting the.
따라서, 자동차의 직진 주행시에는 비구동축(1)의 바퀴(2)가 도 1에 도시된 바와 같이 차량의 전방쪽을 향하도록 조향되어 있는 상태이므로, 이때에는 제동조작수단(30)을 구성하는 압축스프링부재(33)에 장력이 발생되지 않은 상태이며, 이로 인해 상기 비구동축(1)의 모든 바퀴(2)는 구동축 바퀴의 회전수와 동일한 회전수로 회전을 하게 된다.Therefore, the wheel 2 of the non-drive shaft 1 is steered toward the front of the vehicle as shown in FIG. 1 during the straight running of the vehicle. At this time, the compression that constitutes the braking operation means 30 is performed. The tension is not generated in the spring member 33, which causes all of the wheels 2 of the non-drive shaft 1 to rotate at the same speed as the rotation speed of the drive shaft wheels.
그리고, 운전자의 조향핸들 조작에 따라 차량이 선회 주행(코너링 주행)을 시작하게 되면, 비구동축(1)의 바퀴(2)는 모두 도 4에 도시된 바와 같이 선회방향쪽으로 회전을 하게 되며, 이에 따라 선회 중심을 기준으로 하여 내륜측 바퀴(2;I/W)의 휠에 장착된 디스크용 주차브레이크앗세이(10)와 연결되는 압축스프링부재(33)는 탄력적으로 인장작동을 하게 되고, 반대로 외륜측 바퀴(2;O/W)의 휠에 장착된 디스크용 주차브레이크앗세이(10)와 연결되는 압축스프링부재(33)는 탄력적으로 압축작동을 하게 된다.Then, when the vehicle starts turning driving (cornering driving) according to the driver's steering wheel operation, all of the wheels 2 of the non-drive shaft 1 rotate in the turning direction as shown in FIG. Accordingly, the compression spring member 33 connected to the disk parking brake assembly 10 mounted on the wheel of the inner wheel side wheels 2 (I / W) on the basis of the turning center is elastically tensioned and, on the contrary, The compression spring member 33 connected to the parking brake assembly 10 for a disc mounted on the wheel of the outer ring side wheels 2 (O / W) is elastically compressed.
여기서, 압축스프링부재(33)가 인장작동을 하게 되면 플렉시블 와이어(21)가 전술한 바와 같이 도시된 화살표 방향으로 당겨지게 되고, 이에 따라 브레이크슈 레버(13)의 힌지회동에 의해 브레이크슈(14)가 확장되면서 라이닝(15)이 디스크윗부분(16)의 안쪽면에 압착되어 마찰력에 의한 제동력을 발생시키게 되며, 결과적으로 내륜측의 바퀴(2;I/W)는 일정한 속도로서 감속회전을 하게 된다.Here, when the compression spring member 33 is tensioned, the flexible wire 21 is pulled in the direction of the arrow shown as described above, and accordingly the brake shoe 14 is hinged by the brake shoe lever 13. The lining 15 is squeezed to the inner surface of the upper portion of the disk 16 to generate the braking force by the frictional force. As a result, the wheels 2 (I / W) on the inner ring side are decelerated at a constant speed. do.
한편, 상기한 내륜측 바퀴(2;I/W)의 감속회전을 위해 디스크용 주차브레이크앗세이(10)에서 발생되는 제동력은 선회각도(코너링각도)의 크기에 비례하는 크기로서 발생되게 된다.On the other hand, the braking force generated in the disk parking brake assembly 10 for the decelerating rotation of the inner wheel side wheel (2; I / W) is generated as a magnitude proportional to the size of the turning angle (cornering angle).
즉, 선회각도가 완만하면 작은 크기의 제동력이 발생되고 반대로 선회각도가 급격하면 큰 크기의 제동력이 발생되게 된다.That is, when the turning angle is gentle, a small magnitude of braking force is generated. On the contrary, when the turning angle is sharp, a large magnitude of braking force is generated.
그리고, 상기한 압축스프링부재(33)가 압축작동을 하게 되면 플렉시블 와이어(21)는 도시된 화살표의 반대방향으로 밀려지게 되고, 이와 같은 플렉시블 와이어(21)의 움직임은 제동력 발생에 영향을 주지 못하게 되며, 이에 따라 외륜측의 바퀴(2;O/W)는 구동축 바퀴의 회전수와 동일한 회전수로 회전을 하게 된다.In addition, when the compression spring member 33 performs the compression operation, the flexible wire 21 is pushed in the opposite direction to the arrow shown, and the movement of the flexible wire 21 does not affect the braking force generation. Accordingly, the wheels 2 (O / W) on the outer ring side are rotated at the same rotational speed as the rotational speed of the drive shaft wheels.
이와 같이, 본 발명에 따라 비구동축(1)의 바퀴(2)에 디스크용 주차브레이크앗세이(10)를 장착시키고, 이 디스크용 주차브레이크앗세이(10)를 작동하기 위한 제동조작수단(30)을 비구동축(1)과 디스크용 주차브레이크앗세이(10)를 연결하도록 설치하게 되면, 선회 주행(코너링 주행)시 선회 중심을 기준으로 하여 내륜측의 바퀴(2;I/W)는 선회각도의 크기에 비례하는 일정한 크기로서 감속회전을 하게 되고, 외륜측의 바퀴(2;O/W)는 선회각도의 크기에 상관없이 구동축 바퀴의 회전수와 동일한 회전수로서 회전을 하게 된다.Thus, according to the present invention, the disk parking brake assembly 10 is mounted on the wheel 2 of the non-drive shaft 1, and the braking operation means 30 for operating the disk parking brake assembly 10 is performed. ) Is installed to connect the non-drive shaft (1) and the parking brake assembly (10) for the disc, the wheel (2; I / W) of the inner ring side on the basis of the turning center when turning (cornering) The deceleration is rotated as a constant size proportional to the magnitude of the angle, and the wheels 2 (O / W) on the outer ring side are rotated at the same speed as the rotational speed of the drive shaft wheels regardless of the magnitude of the turning angle.
이에 따라, 본 발명에 따른 구성은 기존의 구동축에 장착되는 차동기어장치(differential gear)와 동일한 기능을 발휘하게 되어 차량의 스티어 특성(steer individuality)을 효과적으로 제어함으로써 주행안정성 및 조향안정성에 도움을 줄 수 있게 되고, 특히 본 발명에 따른 구성은 기존의 차동기어장치에 비해 구조가 단순하여 제조시간의 단축 및 원가절감의 잇점이 있을 뿐만 아니라 차량의 전체중량도 대폭적으로 감소시킬 수 있게 됨으로써 연비향상에도 일조를 할 수 있는 잇점이 있게 된다.Accordingly, the configuration according to the present invention has the same function as the differential gear (differential gear) mounted on the existing drive shaft to effectively control the steering individual characteristics (steer individuality) of the vehicle to help the driving stability and steering stability In particular, the configuration according to the present invention has a simple structure compared to the conventional differential gear device, which not only shortens the manufacturing time and costs, but also significantly reduces the overall weight of the vehicle, thereby improving fuel economy. There is an advantage to help.
이상 설명한 바와 같이 본 발명에 의하면, 선회 주행의 방향에 따라 내륜측에 해당되는 바퀴를 일정한 속도로 감속시킬 수 있도록 된 디스크용 주차브레이크앗세이가 비구동축 바퀴의 휠에 장착되어져, 차동기어장치와 동일한 기능을 발휘하면서 차량의 스티어 특성을 효과적으로 제어하여 주행안정성 및 조향안정성을 향상시킬 수 있게 되고, 아울러 제조시간의 단축 및 원가절감을 이룩할 수 있게 되면서 차량의 전체중량도 대폭적으로 감소시킬 수 있는 효과가 있게 된다.As described above, according to the present invention, a disc parking brake assembly is provided on a wheel of a non-drive shaft wheel so that the wheel corresponding to the inner ring side can be decelerated at a constant speed according to the direction of turning travel. It is possible to improve the driving stability and steering stability by effectively controlling the steering characteristics of the vehicle while showing the same function, and also to reduce the overall weight of the vehicle drastically by reducing the manufacturing time and cost.
