본 발명은 마름모식 차륜배열구조를 갖는 자동차에 관한 것으로, 더욱 상세하게로는 차체 길이방향의 대략 중간지점의 좌우측에 좌, 우 중간륜을 서로 대칭되게 배열하고, 차체 전후방의 차폭의 중간지점에 구동과 조향을 병행하는 전륜과 후륜을 각각 배열함으로써, 제자리 360도 회전을 비롯한 다양한 선회기능을 갖고, 선회반경이 감소되며, 선회시 안정성이 향상되고, 전후륜 동시구동으로 풀타임 4륜구동(full-time 4 whell drive)효과를 갖는 마름모식 차륜배열구조를 갖는 자동차에 관한 것이다.The present invention relates to a vehicle having a rhombic wheel arrangement structure, and more particularly, the left and right middle wheels are arranged symmetrically with each other on the left and right sides of an approximately middle point in the longitudinal direction of the vehicle body, By arranging the front and rear wheels in parallel with driving and steering, it has various turning functions including 360-degree rotation in place, reducing turning radius, improving stability when turning, and driving full-time four-wheel drive (front and rear wheels simultaneously). The present invention relates to a vehicle having a rhombic wheel arrangement having an effect of -time 4 whell drive.
또한, 본 발명은 전륜과 후륜이 서로 일직선상에 위치하고, 좌우 중간륜이 서로 독립적으로 회전가능하도록 함으로써, 차동기어등의 구성이 불필요하고 그에 따라 축계손실에 의한 출력 및 효율감소가 방지되고 차체중량이 현저히 감소되는 마름모식 차륜배열구조를 갖는 자동차에 관한 것이다.In addition, according to the present invention, the front wheel and the rear wheel are located in a straight line with each other, and the left and right middle wheels are rotatable independently of each other, thereby eliminating the configuration of a differential gear and the like, thereby preventing output and efficiency from being lost due to shaft loss, and reducing vehicle weight. The present invention relates to a vehicle having a rhombic wheel arrangement which is significantly reduced.
현재, 승용자동차의 경우, 차체의 전방 좌우측에 설치된 두개의 전륜과 후방 좌우측에 설치된 두개의 후륜으로 구성되는 차륜배열구조를 예외없이 채택하고 있다. 그러나, 이와 같은 차륜배열구조는 자동차의 선회시에 여러가지 문제점이 있다. 즉, 조향을 담당하는 전륜의 회전범위가 구조적 제한을 받게되므로, 선회반경이 비교적 길다는 문제점이 있다. 이러한 점은, 최근의 열악한 주차환경을 고려하여 볼때, 더욱 심각한 문제점이 아닐 수 없다. 또한, 자동차의 선회시 좌우측 차륜이 서로 다른 회전반경을 갖게되므로, 각각 서로 다른 회전수로 회전되어야 하기 때문에 차동기어등의 추가적 구성요소를 필요로 하여 차체 중량이 상승된다는 문제점이 있었고, 또한, 차체의 선회시 원심력으로 인해 회전과 바깥방향으로 기울어지므로 회전안정성과 접지력이 저하되어 경우에 따라서는 차체가 전복되는 경우도 있었다.Currently, in the case of a passenger car, a wheel arrangement structure consisting of two front wheels installed on the front left and right sides and two rear wheels installed on the rear left and right sides is adopted without exception. However, such a wheel arrangement structure has various problems when turning a vehicle. That is, since the rotation range of the front wheel that is responsible for steering is subject to structural limitations, there is a problem that the turning radius is relatively long. This is a more serious problem in view of the recent poor parking environment. In addition, since the left and right wheels have different turning radii when the vehicle is turning, the weight of the vehicle is increased because additional components such as differential gears need to be rotated at different rotational speeds. Because of the centrifugal force, the car was inclined in the direction of rotation and outward due to the centrifugal force.
결국, 위와 같은 직사각형식 차륜배열구조는 선회시의 안정성, 선회반경, 차체중량 등에 있어서 여러가지 문제점이 있는 것으로 파악되며, 개선될 여지가 있었음에도 불구하고, 현재까지는 전혀 개선의 시도가 행해지지 않고 있는 실정이다.As a result, the rectangular wheel arrangement structure as described above is considered to have various problems in the stability, turning radius, body weight, etc. at the time of turning, and although there is room for improvement, no attempt has been made to improve until now. It is true.
따라서, 본 발명의 목적은, 제자리 360도 회전등을 비롯한 다양한 선회기능을 갖고 선회반경이 감소되며 선회시의 안정성이 향상된 마름모식 차륜배열구조를 갖는 자동차를 제공하는 데에 있다.Accordingly, an object of the present invention is to provide a vehicle having a rhombus wheel arrangement structure having various turning functions including a 360-degree rotation lamp in place, a turning radius being reduced, and improved stability during turning.
본 발명의 또 다른 목적은, 차체 전후방의 차폭의 중간지점에 차체 길이방향으로 일직선상에 배열된 전륜과 후륜을 동시구동함으로써 4륜조향의 기능을 갖는 마름모식 차륜배열구조를 갖는 자동차를 제공하는 데에 있다.It is still another object of the present invention to provide a vehicle having a rhombic wheel arrangement structure having a four-wheel steering function by simultaneously driving the front and rear wheels arranged in a straight line in the longitudinal direction of the vehicle body at an intermediate point of the vehicle width in front and rear of the vehicle body. There is.
본 발명의 또 다른 목적은, 차체 길이방향의 대략 중간지점의 좌우측에 좌우 중간륜을 서로 대칭되게 설치하고, 이 좌우 중간륜이 제각기 독립적으로 회전할 수 있도록 함으로써, 차동기어를 설치하지 않고도 선회등이 가능하며 따라서 차체중량이 현저히 감소되는 마름모식 차륜배열구조를 갖는 자동차를 제공하는 데에 있다.Another object of the present invention is to install the left and right middle wheels symmetrically with each other on the left and right sides of the midway point in the longitudinal direction of the vehicle body, and to allow the left and right middle wheels to rotate independently of each other, so that the turning wheel is not provided with a differential gear. It is possible to provide a vehicle having a rhombus wheel arrangement structure in which this is possible and thus the body weight is significantly reduced.

이하, 첨부도면을 참조하여 본 발명의 바람직한 실시예에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
제1도는 본 실시예에 따르는 섀시구조와 차륜배열구조를 도시하는 개략도이다.1 is a schematic diagram showing a chassis structure and a wheel arrangement structure according to the present embodiment.
제1도에 도시한 바와 같이, 차체 길이방향의 중간지점에 메인프레임(1)이 설치되며, 이 메인프레임(1)의 좌우측에는 좌측중간륜(2) 및 우측중간륜(2')이 서로 대칭되게 설치된다. 또한, 이 메인프레임(1)의 전방양 측단에는 전륜지지프레임(3)이 힌지결합되며, 후방양측단에는 후륜지지프레임(4)이 힌지결합된다. 따라서, 이 전륜지지프레임(3)과 후륜지지프레임(4)은 각각의 힌지결합된 지점을 축으로 하여 메인프레임(1)에 대해 소정각도범위내에서 회전가능하다.As shown in FIG. 1, the main frame 1 is installed at an intermediate point in the longitudinal direction of the vehicle body, and the left middle wheel 2 and the right middle wheel 2 'are mutually disposed on the left and right sides of the main frame 1. It is installed symmetrically. In addition, the front wheel support frame 3 is hinged to both front ends of the main frame 1, and the rear wheel support frame 4 is hinged to both rear ends. Therefore, the front wheel support frame 3 and the rear wheel support frame 4 are rotatable within a predetermined angle range with respect to the main frame 1 around the respective hinged points.
이 전륜지지프레임(3)의 차폭방향의 중간지점에는 전륜지지프레임(5)가 설치되며, 후륜지지프레임(4)의 차폭방향의 중간지점에는 후륜지지부(6)가 설치된다. 전륜지지부(5)의 단부에는 전륜(7)이 설치되며, 후륜지지부(6)의 단부에는 후륜(8)이 설치된다.A front wheel support frame 5 is provided at an intermediate point in the vehicle width direction of the front wheel support frame 3, and a rear wheel support 6 is provided at an intermediate point in the vehicle width direction of the rear wheel support frame 4. The front wheel 7 is installed at the end of the front wheel support 5, and the rear wheel 8 is installed at the end of the rear wheel support 6.
따라서, 좌측중간륜(2)와 우측중간륜(2') 및 전륜(7)과 후륜(8)은 차체 중심에 대해 각각 서로 대칭이며, 마름모형을 배열된다.Accordingly, the left middle wheel 2 and the right middle wheel 2 ', the front wheel 7 and the rear wheel 8 are symmetrical with respect to the center of the vehicle body, respectively, and are arranged in a rhombus.
한편, 전륜지지프레임(3)과 후륜지지프레임(4)이 각 양측에는 소정의 설정압력으로 이들을 탄성바이어스하는 완충장치가 설치되는 바, 본 실시예의 경우, 각 일단은 전륜지지프레임(3) 및 후륜지지프레임(4)에 지지되고, 각 타단은 차체(도시생략)에 지지되는 통상의 코일스프링(9, 9', 9″, 9″')이 설치된다. 또한, 좌우측 중간륜(2, 2')도 역시 통상의 띠스프링(10, 10')에 의해 메인프레임(1)에 대해 탄성바이어스된다.On the other hand, the front wheel support frame (3) and the rear wheel support frame (4) is provided on each side is provided with a shock absorber for elastically biasing them at a predetermined set pressure, in this embodiment, each end is a front wheel support frame (3) and Normal coil springs 9, 9 ', 9 ", 9"' are supported by the rear wheel support frame 4 and each other end is supported by a vehicle body (not shown). In addition, the left and right intermediate wheels 2, 2 'are also elastically biased with respect to the main frame 1 by means of conventional belt springs 10, 10'.
한편, 전륜(7)과 후륜(8)은 조향과 구동을 병행하도록 구성되어 있는 바, 전륜지지부(5)와 후륜지지부(6)는 각각 전륜지지프레임(3)과 후륜지지프레임(4)에 대해 소정각도범위내에서 회전(조향)가능하며, 전륜(7)과 후륜(8)은 각각 전륜지지부(5)과 후륜지지부(6)에 대해 회전(구동)가능하도록 되어 있다. 이러한 구성과 작동을 제2도에 의해 이하에서 설명한다.On the other hand, the front wheel 7 and the rear wheel 8 is configured to handle and drive in parallel, the front wheel support portion 5 and the rear wheel support portion 6 to the front wheel support frame 3 and the rear wheel support frame 4, respectively. It can be rotated (steered) within a predetermined angle range, and the front wheel 7 and the rear wheel 8 are rotatable (driven) with respect to the front wheel support 5 and the rear wheel support 6, respectively. This configuration and operation will be described below with reference to FIG.
제2도에서는 전륜지지프레임(3)과 이 전륜지지프레임(3)에 설치된 전륜지지부(5) 및 이 전륜지지부(5)에 설치된 전륜(7)을 도시하고 있다. 전륜과 후륜은 대칭이므로 후륜의 경우는 별도의 설명이 없이도 이해되어 질 수 있을 것이다.In FIG. 2, the front wheel support frame 3, the front wheel support part 5 provided in this front wheel support frame 3, and the front wheel 7 provided in this front wheel support part 5 are shown. Since the front and rear wheels are symmetrical, the rear wheels can be understood without further explanation.
전륜지지부(5)의 전륜지지프레임(3)과 결합된 일단에는 전륜지지부(5) 자체의 회전축인 외축(11)이 형성되며, 이 외축(11)의 내부에는 외축(11)회전시에는 외축 (11)과 함께 회전함과 동시에 외축(11)과는 독립적으로 회전가능한 내축(12)이 설치된다. 이 외축(11)과 내축(12)은 모두 전륜지지프레임(3)의 내부에 수용되며, 외축 (11)은 조향축(13)과 기어결합되고, 내축(12)은 구동축(14)과 기어결합된다. 전륜지지부(5)의 기어 결합되고, 내축(12)은 구동축(14)과 기어결합된다. 전륜지지부(5)의 내부에는 전술한 내축(12)으로부터의 회전을 전륜(7)까지 전동하는 복수개의 기어 (15, 16, 17, 18)가 설치된다.At one end coupled to the front wheel support frame 3 of the front wheel support 5, an outer shaft 11, which is a rotation shaft of the front wheel support 5 itself, is formed, and the outer shaft 11 is rotated when the outer shaft 11 is rotated. At the same time as rotating with the (11) and the inner shaft (12) rotatable independently of the outer shaft (11) is provided. Both the outer shaft 11 and the inner shaft 12 are accommodated in the front wheel support frame 3, the outer shaft 11 is gear-coupled with the steering shaft 13, and the inner shaft 12 is geared with the drive shaft 14. Combined. The gear of the front wheel support 5 is coupled, the inner shaft 12 is geared with the drive shaft (14). Inside the front wheel support part 5, a plurality of gears 15, 16, 17, 18 for transmitting the rotation from the inner shaft 12 to the front wheels 7 are provided.
이와 같은 구성에 의해, 조향축(13)이 회전하면, 이와 기어결합된 전륜지지부 (5)의 외축(11)이 회전하므로, 전륜지지부(5)자체가 소정각도 회전하여 조향이 이루어진다. 한편, 구동축(14)이 회전하면, 이와 기어 결합된 전륜지지부(5)내부의 내축(12)이 회전하므로, 이 내축(12)이 회전에 의해 전동되는 전륜(7)이 회전하여, 결국 구동이 이루어진다. 이러한 조향과 구동은 각각 개별적으로 또는 병행하여 이루어질 수 있다. 미설명부호(19)은 전륜(7)의 제동을 위한 통상의 브레이크수단을 나타낸다.With this configuration, when the steering shaft 13 rotates, the outer shaft 11 of the front wheel support 5 geared thereto rotates, so that the front wheel support 5 itself rotates by a predetermined angle to steer. On the other hand, when the drive shaft 14 rotates, the inner shaft 12 inside the front wheel support portion 5 coupled to the gear rotates, so that the front wheel 7 to which the inner shaft 12 is driven by the rotation rotates and eventually drives. This is done. Such steering and driving may be carried out individually or in parallel. Reference numeral 19 denotes conventional brake means for braking the front wheels 7.
한편, 후륜(8)의 경우는 전술한 전륜(7)과 동일한 구조이지만, 단지 조향축 (12)에 설치된 역전수단(도시하지 않음)에 의해 전륜(7)과 반대방향으로 회전하도록 구성된다. 제3도에서는 이와 같은 구성에 의해, 조향시 전륜(7)과 후륜(8)이 서로 반대방향으로 회전하는 상태를 도시하고 있다.On the other hand, the rear wheel 8 has the same structure as the front wheel 7 described above, but is configured to rotate in the opposite direction to the front wheel 7 only by reversing means (not shown) provided on the steering shaft 12. In FIG. 3, this configuration shows a state in which the front wheels 7 and the rear wheels 8 rotate in opposite directions during steering.
이하, 제4도(a)도 및 제4도(b)에 의해, 본 실시예에 의한 섀시구조와 차륜배열을 갖는 자동차의 조향시의 작동을 설명한다.4 (a) and 4 (b), the operation during steering of an automobile having a chassis structure and a wheel arrangement according to the present embodiment will be described.
제4도(a)는 조향을 위해 전륜(7)과 후륜(8)을 대략 45도 회전시켰을 때의 조향상태를 도시하며, 제4도(b)는 전륜(7)과 후륜(8)을 대략 90도 회전시켜서 제자리 360도 회전을 하는 상태를 도시한다. 자동차의 선회시, 회전방향의 내측과 외측에 각각 위치하여 서로 다른 회전반경을 갖는 좌우 중간륜(2, 2')은 서로 회전수가 달져여 하고 보통은 차동기어(differential gear)에 의해 이러한 작동을 얻고 있지만, 본 실시예의 경우 이 좌우 중간륜(2, 2')은 차축에 의해 서로 연결되어 있지 않고, 각각 자유롭게 회전가능하므로, 차동기어 등의 구성이 불필요하다. 그리고, 전륜과 후륜은 차체의 종방향 중심선상에 일직선으로 배열되어 있으므로, 동일한 회전반경을 갖게 되므로 역시 차동기어가 불필요하다.FIG. 4 (a) shows the steering condition when the front wheel 7 and the rear wheel 8 are rotated approximately 45 degrees for steering, and FIG. 4 (b) shows the front wheel 7 and the rear wheel 8 It shows the state which rotates about 90 degrees and rotates 360 degrees in place. When turning a car, the left and right middle wheels 2 and 2 ', which are located inside and outside of the rotation direction and have different turning radii, should be rotated with each other and are normally operated by differential gears. However, in the present embodiment, the left and right intermediate wheels 2, 2 'are not connected to each other by the axles, and can be freely rotated, respectively, so that a configuration of a differential gear or the like is unnecessary. In addition, since the front wheels and the rear wheels are arranged in a straight line on the longitudinal center line of the vehicle body, they have the same rotation radius, so that differential gears are unnecessary.
본 실시예에 있어서, 다른 구성부분들은 통상의 자동차에서 사용되고 있는 것들과 대동소이하므로, 설명을 생략한다.In the present embodiment, the other components are similar to those used in a typical automobile, and thus description thereof is omitted.
이상 설명한 바와 같이 본 발명의 마름모식 차륜배열구조를 갖는 자동차는, 제자리 360도 회전등 다양한 선회기능을 가지며, 선회반경이 대폭 감소하고, 선회시의 안정성 향상된다. 또한, 일직선상에 배열된 전, 후륜을 동시에 구동할 수 있으므로, 공지의 풀타임 4륜구동차의 장점을 겸비할 수 있다. 또한, 차동기어등을 장착하지 않으므로 축계동력손실이 일어나지 않으며 차체중량을 현저히 감소시킬 수 있다.As described above, the vehicle having the rhombus-type wheel arrangement structure of the present invention has various turning functions such as 360-degree rotation in place, greatly reducing the turning radius and improving stability at the time of turning. In addition, since the front and rear wheels arranged in a straight line can be driven simultaneously, it is possible to combine the advantages of the known full-time four-wheel drive vehicle. In addition, since no differential gear is installed, shaft power loss does not occur and the body weight can be significantly reduced.
