Description

세미트레일링암형(SEMI TRAILING ARM TYPE) 뒤현가장치의 콘트롤암(CONTROL ARM) 고정구조Semi-Trailing Arm Type Control Arm Fixed Structure of Rear Suspension System

본 고안은 세미트레일링암형(SEMI TRAILING ARM TYPE) 뒤현가장치의 콘트롤암(CONTROL ARM) 고정구조에 관한 것으로, 보다 자세하게는 세미트레일링암형 뒤현가장치에서 리어 론지튜디널에 서브 후레임을 완충 가능한 구조로 고정하고, 바퀴를 고정 지지하는 콘트롤 암의 외측 고정단부를 서브 후레임에 상하로 회동가능하게 고정한 세미트레일링암형(SEMI TRAILING ARM TYPE) 뒤현가장치의 콘트롤암(CONTROL ARM) 고정구조에 관한 것이다.The present invention relates to a control arm fixing structure of a semi-trailing arm type rear suspension system, and more specifically, it is possible to buffer a sub frame to a rear longitude body in a semi-trailing arm type rear suspension system. A semi-trailing arm type that secures the structure and fixes the outer fixing end of the control arm for holding and supporting the wheel to the subframe so that it can be rotated up and down is related to the control arm fixing structure of the rear suspension system. will be.

현가장치는 차축과 차체사이에 스프링을 두고 연결하여 주행할 때 차축이 노면에서 받는 진동이나 충격을 차체에 직접 전달되지 않도록하여 차체나 하물(荷物)의 손상을 방지하고 승차감을 좋게 하는 장치로서, 차축의 형식에 따라 크게 차축현가식(또는 일체차축식)과 독립현가식(분할차축식)으로 나눌 수 있다.Suspension is a device that prevents damage to the car body or cargo and improves the ride quality by preventing the axle from being directly transmitted to the car body when driving by connecting a spring between the axle and the car body. Depending on the type of axle, it can be divided into axle suspension type (or integral axle type) and independent suspension type (divided axle type).

차축현가식은 바퀴가 좌우로 연결된 한 개의 차축을 스프링으로 차체에 연결시킨 형식이며, 강도가 크고 구조가 간단하기 때문에 대형 트럭이나 버스에서 많이 사용된다. 한편, 독립현가식은 차축식과 같이 차축과 현가의 구별이 명확하지 하지않으나 일반적으로 좌우의 바퀴가 독립적으로 차체에 고정되어 노면으로부터의 충격에 개별적으로 대응되도록 하는 형식이며, 승차감이 좋고 안정성 및 조정성이 뛰어나기 때문에 승용차와 같은 소형차량에 많이 사용된다.The axle suspension type is a type in which one axle with wheels connected to the left and right is connected to the body by a spring. It is widely used in heavy trucks and buses because of its high strength and simple structure. On the other hand, the independent suspension type is not clearly distinguished from the axle and the suspension, as in the case of the axle type, but in general, the left and right wheels are independently fixed to the vehicle body to individually respond to the impact from the road surface, and the ride comfort is good and stability and adjustability Because of its superiority, it is widely used in small vehicles such as passenger cars.

독립식은 다시 구조에 따라 위시보운형, 맥퍼슨형, 트레일링암형, 세미트레일링암형, 다이애거널 링크형 및 스윙차축형으로 나눌수 있는데 상기 위시보운형, 맥퍼슨형 및 트레일링형은 일반적으로 앞현가장치로 많이 사용되고, 그 밖의 세미트레일링암형, 다이애거널 링크형 및 스윙차축형은 뒤현가장치로 많이 사용된다.Independent type can be divided into Wishbone type, McPherson type, trailing arm type, semi-trailing arm type, Diagonal link type and swing axle type according to the structure. The wishbone type, McPherson type and trailing type are generally used as front suspension devices. It is widely used, and other semi-trailing arm type, die- nal link type and swing axle type are widely used as rear suspension.

그중에서 세미트레일링암형(SEMI TRAILING ARM TYPE)은 트레일링암형과 스윙차축형의 중간적인 현가장치로서 도 1에 도시된 바와 같이 차축과 바퀴를 고정 지지하며 차체에 상하로 회동되는 구조로 고정된 콘트롤암(CONTROL ARM)(20)과, 상기 콘트롤암(20)을 차체에 고정해주며 보강후레임 역할을 하는 현가 멤버(40)와, 충격을 흡수하는 코일 스프링(42)과 쇽업쇼버(44)로 이루어지며 이 형식은 콘트롤암(20)이 뒤쪽으로 비스듬히 돌출되고, 바퀴가 상하로 움직이면 윤거, 캠버 및 토우각도가 변화된다.Among them, the semi-trailing arm type is an intermediate suspension device of the trailing arm type and the swing axle type. The semi-trailing arm type is fixed in a structure that is fixed to the axle and the wheel and rotates up and down on the body as shown in FIG. A control arm 20, a suspension member 40 which fixes the control arm 20 to the vehicle body and serves as a reinforcement frame, a coil spring 42 and a shock absorber 44 which absorb shocks. In this type, the control arm 20 protrudes obliquely to the rear, and the wheels move up and down to change the lubrication, camber and toe angles.

상기와 같은 종래의 세미트레일링형 뒤현가장치는 콘트롤암이 현가 멤버에 직접 고정되는 구조로 되어있기 때문에 요철부와 충돌되는 경우 충격이 바로 차체로 전달되어 승차감을 나쁘게 하며, 측면으로부터 가해지는 횡력에 대해서는 구조상 취약한 문제점이 있다.The conventional semi-trailing type rear suspension as described above has a structure in which the control arm is directly fixed to the suspension member, so when a collision occurs with the uneven part, a shock is immediately transmitted to the vehicle body, resulting in a bad ride, and a lateral force applied from the side. There is a weak structural problem.

본 고안은 상기와 같은 문제점을 해결하기 위한 것으로, 그 목적은 주행중 에 바퀴가 요철부와의 충돌로 인하여 발생된 충격이 바로 차체로 전달되는 것을 방지하고, 아울러 승차감을 향상시키며, 바퀴의 측면에서 가해지는 충격에 트레일링암의 고정부가 파손되지 않도록 하기 위한 새로운 형태의 세미트레일링암형(SEMI TRAILING ARM TYPE) 뒤현가장치의 콘트롤암(CDNTROL ARM) 고정구조를 제공하고자 하는 것이다.The present invention is to solve the above problems, the purpose is to prevent the impact of the wheels due to the bumps and bumps during the driving immediately transmitted to the vehicle body, and also to improve the ride comfort, in terms of the wheels It is to provide a new type of semi-trailing arm (CDNTROL ARM) fixed structure for the rear suspension to prevent the trailing arm fixing part from being damaged by the impact.

이러한, 목적을 달성하기 위하여, 본 고안은 세미트레일링암형 뒤현가장치의 콘트롤 암 고정구조에 있어서, 상기 콘트롤 암의 내측 고정단부와 외측 고정단부는 리어 론지튜디널의 고정 브라켓과 서브후레임에 각각 상하로 회동가능한 구조로 고정되고, 상기 서브후레임은 고정부의 부시에 나사관통공이 상하로 관통된 고무 부시가 상하로 삽입되고 고정볼트에 의해 나사관통공이 형성된 리어 론지튜디널의 상부 소정 위치에 고정된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a control arm fixing structure of a semi-trailing arm type rear suspension device, wherein the inner fixing end and the outer fixing end of the control arm are respectively fixed to the fixing bracket and the subframe of the rear longue tunnel. The subframe is fixed to the upper rotatable structure, and the subframe is fixed to the upper part of the rear longue tunnel where a rubber bush having a screw through hole vertically penetrated into the bush of the fixing part is inserted up and down and a screw through hole is formed by a fixing bolt. It is characterized by.

A disk-shaped fixing part 14 having a bush 15 is formed at the front end 11 side and the rear end 12, and the bracket 16 is provided at a predetermined position on the outer peripheral surface 13 of the front end 11 side. The formed subframe 10 is fixed to the trust 29, and the outer fixed end 24 of the control arm 20 having the knuckle 22 fixing the wheel at one end thereof is the subframe 10. Is fixed to the bracket (16) of the rotatable structure and the inner fixing end 26 is the rear A strut bar 29 which is fixed to the stationary bracket 5 of the dinar 1 and is prevented from being twisted is installed on the knuckle 22 of the control arm 20 and the stationary bracket 5. .

한편, 상기 서브후레임(10)은 도 4에 도시된 바와 같이 상하로 나사관통공(32)이 상하로 관통되고, 일측 단부에 원형의 걸림편(34)이 형성된 소정 형상의 고무 부시(30)가 고정부(14) 부시(15)에 상하로 삽입되어 나사관통공(4)이 형성된 리어 론지튜디널(1)의 상부면(3)에 밀착되며, 상기 고무 부시(30)의 상부에 와셔(36)가 얹혀지는 한편, 볼트(37)가 상부로부터 나사관통공(4)(32)에 삽입되어 너트(38)와 체결되어 고정된다.On the other hand, the sub frame 10 is a rubber bush 30 of a predetermined shape in which the screw through hole 32 penetrates up and down as shown in FIG. 4, and a circular locking piece 34 is formed at one end thereof. Is inserted into and fixed to the bushing 15 of the fixing portion 14 to be in close contact with the upper surface (3) of the rear long-terminal (1) formed with a threaded through hole (4), washer on the top of the rubber bush (30) While the 36 is placed, the bolt 37 is inserted into the screw through hole 4 and 32 from the top, and is fastened and fixed with the nut 38.

상기와 같이 결합 고정된 본 고안은 차량의 주행중 노면의 요철부와 바퀴가 충돌하여 상기 바퀴를 후방으로 미는 힘이 발생될 때, 그 힘은 상기 콘트롤암(20)을 통하여 양측 고정단부가 고정된 서브후레임(10)과 고정브라켓(5)을 거쳐 차체로 전달되는데 이때, 상기 서브후레임(10)은 앞뒤 고정부(14)에 장착된 고무 부시(30)의 전면이 압축되면서 상기 힘을 흡수 완화시키며, 흡수되지 못한 힘의 상당 부분은 코일 스프링과 쇽업쇼버가 압축되며 흡수 완화시킨다.The present invention coupled and fixed as described above, when a force that pushes the wheel to the rear by the bumps and bumps on the road surface of the vehicle while driving, the force is fixed to both sides through the control arm 20 The sub frame 10 and the fixing bracket 5 are transmitted to the vehicle body, in which the sub frame 10 absorbs and absorbs the force while the front surface of the rubber bush 30 mounted on the front and rear fixing parts 14 is compressed. Much of the unabsorbed force causes the coil spring and shock absorber to compress and absorb.

본 고안은 콘트롤암을 통하여 전달되는 충격을 중간에서 흡수 완하시키기 때문에 차체로 전달되는 충격을 최소화 할 수 있으며, 아울러 승차감이 향상된다. 또한, 콘트롤암의 고정부가 파손되는 것이 방지되는 효과도 있다.The present invention can minimize the shock transmitted to the vehicle body to absorb the shock transmitted through the control arm in the middle, and the ride comfort is improved. In addition, there is an effect that the fixing portion of the control arm is prevented from being broken.
