Description
본 발명은 차량용 차축 현가장치의 롤 방지구조에 관한 것으로서, 보다 상세하게는 차축에 비틀림 부재를 스플라인 결합하여 롤 현상을 억제함으로써 더욱 향상된 승차감을 얻을 수 있도록 하는 차량용 차축 현가장치의 롤 방지구조에 관한 것이다.The present invention relates to a roll preventing structure of a vehicle axle suspension device, and more particularly, to a roll preventing structure of a vehicle axle suspension device to obtain a more comfortable ride by suppressing a roll phenomenon by spline coupling a torsion member to the axle. will be.
일반적으로 차량용 현가장치는 차체 사이에 스프링을 두고 연결하여 주행할 때 차축이 노면에서 받는 진동이나 충격을 차체에 직접 전달되지 않도록 하여 차체나 화물의 손상을 방지하고 승차감을 향상시키기 위한 장치로서, 노면에서 받는 충격을 완화하는 섀시 스프링과 섀시 스프링의 자유 진동을 억제하여 승차감을 좋게 하는 쇽 업소버 및 자동차가 옆으로 흔들리는 것을 방지하는 스테이빌라이저 등으로 구성된다.In general, a vehicle suspension device is a device for preventing damage to the vehicle body or cargo and improving riding comfort by preventing the axle from directly transmitting the vibration or shock received from the road surface when the vehicle is connected with a spring between the vehicle bodies. It consists of a chassis spring that mitigates the shock from the shock absorber, a shock absorber that suppresses free vibration of the chassis spring to improve ride quality, and a stabilizer that prevents the vehicle from shaking sideways.
또한, 현가장치는 구동 바퀴에 발생하는 구동력이나 제동할 때에 각 바퀴의 제동력을 차체에 전달함과 동시에 선회할 때의 원심력에도 견디고, 각 바퀴를 차체에 대해 바른 위치로 지지하며, 이러한 역할을 수행하기 위하여 노면에서 받는 충격을 완화하기 위하여 상하 방향으로 움직일 수 있는 상태의 결합이 필요하고, 바퀴에 발생하는 구동력, 제동력 및 선회할 때의 원심력 등에 견딜 수 있도록 수평 방향으로 강한 결합이 필요하게 된다.In addition, the suspension system transmits the driving force generated on the driving wheels or the braking force of each wheel to the vehicle body at the time of braking, and withstands the centrifugal force when turning, and supports each wheel in the correct position with respect to the vehicle body, and performs this role. In order to alleviate the impact received from the road surface is required to be coupled in a state capable of moving in the up and down direction, a strong coupling in the horizontal direction is required to withstand the driving force, braking force and centrifugal force generated when turning.
종래의 현가장치에서 특히 차축 현가식은 차량의 앞 또는 뒤에 적용되는데, 이는 도 1에 도시한 바와 같이 차축 하우징(10)의 양측에 바퀴(11)(12)가 결합되고, 상기 차축 하우징(10)에는 동력을 전달하는 프로펠러 샤프트(13)가 결합되고, 상기 차축 하우징(10)에는 차량의 롤링을 억제하기 위한 "ㄷ"자 형상의 스테이빌라이저(14)가 고정되고, 상기 스테이빌라이저(14)의 양단은 차체에 고정되도록 구성된다.In conventional suspensions, in particular, the axle suspension is applied to the front or the rear of the vehicle, which is coupled with wheels 11 and 12 on both sides of the axle housing 10 as shown in FIG. A propeller shaft 13 for transmitting power is coupled to the axle housing 10, and a stabilizer 14 having a “c” shape for suppressing rolling of the vehicle is fixed to the axle housing 10, and the stabilizer 14 is fixed to the axle housing 10. Both ends of the) are configured to be fixed to the vehicle body.
그러나 이와 같은 종래의 차축 현가장치는 스테이빌라이저가 차축 하우징 및 차체에 고정됨에 따라 차량의 주행중 바퀴의 상하방향 이동량에 대해 차축과 연동되는 스테이빌라이저의 이동량이 미미하여 차량의 롤링을 억제하는 효과가 적을 뿐만 아니라 이를 개선하기 위해서 스테이빌라이저의 선경을 크게 하여야 함으로써 취부구조에서 내구성이 저하되고 코스트가 상승되는 문제점이 있다.However, the conventional axle suspension device has a small amount of movement of the stabilizer linked with the axle with respect to the vertical movement amount of the wheels while the vehicle is being driven, since the stabilizer is fixed to the axle housing and the vehicle body. In order to improve this problem, however, the diameter of the stabilizer must be increased, resulting in a decrease in durability and a cost increase in the mounting structure.
따라서, 본 발명은 상술한 종래 기술의 문제점들을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 상대적으로 작은 선경의 비틀림 부재를 차축 하우징의 상측 또는 하측에 스플라인 결합함으로써 취부구조의 내구성을 향상시킴과 아울러 코스트를 절감하고, 공간적으로 비틀림 부재의 배치에 제약을 받지 않으며 차량을 경량화시킬 수 있는 차량용 차축 현가장치의 롤 방지구조를 제공하는데 있다.Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, the object of the present invention is to improve the durability of the mounting structure by spline coupling a relatively small twisting member of the wire diameter to the upper or lower side of the axle housing and In addition, the present invention provides a roll preventing structure of a vehicle axle suspension device that can reduce cost and is not restricted by the arrangement of the torsional member in space, and can reduce the weight of the vehicle.

It is possible to reduce the weight of the vehicle and to be easy to install since it is not restricted by the installation.
이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도 2 는 본 발명에 의한 차량용 차축 현가장치의 롤 방지구조를 도시한 일부 사시도로서, 차축 하우징(20)의 양단에는 바퀴(21)(22)가 결합되어 있고, 상기 차축 하우징(20)의 감속부(23)에는 동력을 전달하는 프로펠러 샤프트(24)가 결합되어 있다.2 is a partial perspective view showing a roll preventing structure of the vehicle axle suspension according to the present invention, wherein wheels 21 and 22 are coupled to both ends of the axle housing 20, and the deceleration of the axle housing 20 is performed. Part 23 is coupled to the propeller shaft 24 for transmitting power.
그리고, 상기 감속부(23)에는 선단이 도시하지 않은 크로스 멤버 등의 차체에 고정되는 비틀림 부재(30)가 결합 부재(40)를 개재하여 결합되는데, 이는 도 3 에 도시한 바와 같이 비틀림 부재(30)의 일단에는 스플라인부(31)가 형성되어 있고, 상기 결합 부재(40)는 상기 차축 하우징(20)에 장착되는 고정부(41)와, 유니버셜 조인트(42) 그리고 상기 비틀림 부재(30)의 스플라인부(31)가 스플라인 결합으로 삽입되는 결합부(43)가 각각 형성되어 있다.In addition, a torsion member 30 fixed to a vehicle body such as a cross member (not shown) is coupled to the reduction unit 23 via a coupling member 40, which is illustrated in FIG. 3. A spline portion 31 is formed at one end of the 30, and the coupling member 40 includes a fixing portion 41 mounted to the axle housing 20, a universal joint 42, and the torsion member 30. Coupling portions 43 into which spline portions 31 are inserted by spline coupling are formed, respectively.
물론, 상기 비틀림 부재(3)의 타단은 크로스 멤버 등의 차체측에 취부되는데, 그 구조는 원하는 기구학적인 자유도를 구현하기 위하여 상기 결합부재(40)와 동일한 구성, 예컨대 고정부, 유니버셜 조인트 그리고 스플라인 결합으로 결합되는 결합부가 동일한 구성으로 이루어진다.Of course, the other end of the torsion member 3 is mounted on the side of the vehicle body such as a cross member, the structure of which is the same configuration as the coupling member 40, for example, a fixing part, a universal joint and a spline, in order to realize a desired kinematic degree of freedom. Coupling portions coupled by coupling are made of the same configuration.
유니버셜 조인트는 롤회전방향 이외의 회전방향에 대한 자유도를 부여합니다. 롤회전 방향을 억제하는 것이 기본 목적으로 스플라인 결합에 의해 롤회전방향은 자유도가 구속됩니다.Universal joints provide degrees of freedom for rotational directions other than the direction of roll rotation. The primary purpose of suppressing the direction of roll rotation is to restrict the degree of freedom in the direction of roll rotation by spline coupling.
이와 같이 구성된 본 발명에 의한 차량용 차축 현가장치의 롤 방지구조는 차축 하우징(20)의 감속부(23)에 결합 부재(40)의 고정부(41)를 체결 고정하고, 상기결합 부재(40)의 결합부(43)에 비틀림 부재(30)의 스플라인부(31)를 스플라인 결합한 후 상기 비틀림 부재(30)의 타단을 크로스 멤버 등의 차체에 고정시키면 장착이 완료된다.The roll preventing structure of the vehicle axle suspension according to the present invention configured as described above is fastened and fixed to the fixing portion 41 of the coupling member 40 to the deceleration portion 23 of the axle housing 20, the coupling member 40 The spline portion 31 of the torsion member 30 is splined to the coupling portion 43 of the torsion member 30, and then fixing the other end of the torsion member 30 to a vehicle body such as a cross member is completed.

따라서, 차량의 주행시 상하 방향으로의 롤링이 발생하면 비틀림 부재(30)가 차체 측과 스프링 하부의 상대적인 롤 회전량에 의해 직접적으로 비틀리게 됨으로써 롤 현상이 억제되는 것이다.Therefore, when rolling in the up-down direction occurs when the vehicle is running, the torsion member 30 is directly twisted by the relative roll rotation amount of the vehicle body side and the spring lower portion, thereby suppressing the roll phenomenon.
그리고, 상기 비틀림 부재(30)가 유니버셜 조인트(42)를 갖는 결합 부재(40)에 결합됨에 따라 차체 측과 차축 하우징(20)의 상대적인 운동에 의해 병진방향과 롤 회전방향 이외의 회전방향에도 기구학적인 자유도가 부여되어 그 작동이 원활하게 이루어지게 된다.In addition, as the torsion member 30 is coupled to the coupling member 40 having the universal joint 42, the kinematics is also improved in the rotational direction other than the translation direction and the roll rotation direction by the relative movement of the vehicle body side and the axle housing 20. Freedom is given so that the operation is smooth.
