Abstract

A turn-about system for a vehicle being at a standstill comprises a pivot post (2) mounted on one end portion of a rear axle housing (1) by two hydraulic cylinders (8,13), and an auxiliary wheel (4) mounted on the center portion of a front axle housing (3) by the other two hydraulic cylinders (14,17). The pivot post has a base plate (9) which is ball-jointed to the piston rod (8a). Two front wheels (6) are lifted by the cylinder (14) mounting the auxiliary wheel, and one rear wheel (5) near the pivot post is also lifted by the cylinder (8) , and then the remaining rear wheel is used as a drive wheel in changing the course of the vehicle.

본 발명은 자동차를 제자리에서 원하는 방향으로 회전시킬 수 있는 가장 간편하고 안전한 방법을 제공함에 목적이 있는 것이다.It is an object of the present invention to provide the simplest and safest way to rotate a vehicle in place in the desired direction.

자동차는 앞, 뒤액슬 좌, 우 양단에 차바퀴가 축설되어 있고 이 차바퀴는 지면에 닿아 있으므로 자동차를 제자리에서 원하는 방향으로 회전시킬려면 각 차바퀴가 지면에서 떨어지도록 차체를 들어올린 다음 회전시키지 않으면 다른 방도가 없는 것이다. 그런데 각 바퀴를 지면에서 떨어지도록 차체를 들어올리는 일은 용이한 문제가 아니며 설사 들어올린다 하더라도 중량이 큰 차체를 들어올리기 위한 장치는 여간 복잡한 장치에 의하지 아니하고는 달성할 수 없는 것으로 생각되지 때문에 본 발명은 이러한 문제점을 감안하여 가장 간편하고 안전한 방법을 구상한 결과 뒤액슬하우징의 일측을 들어 그쪽 바퀴가 지면에서 들리게 함과 동시에 앞쪽 바퀴도 지면에서 돌리게 하고 뒤액슬을 들어올린 축지부를 기점으로 하여 지면에 닿아있는 타측바퀴를 돌리면 타측바퀴의 회전방향과 동일한 방향으로 자동차의 앞쪽이 좌, 우로 회전하게 되는바 축지부의 중심선상에 직각을 이루는 방향으로 안내바퀴를 설치해주어 차체를 자연스럽게 제자리에서 360도로 회전가능하게 하였는바 본 발명을 첨부도면에 의서 상세히 설명하면 다음과 같다. 자동차의 뒤액슬하우징(1) 일측하부에 축지부(2)를 설치하며, 앞액슬(3)의 중앙하부에 안내바퀴(4)를 축지부(2)의 중심선상(A)에 직각으로 설치하여 축지부축 차바퀴(5)와 앞쪽 양바퀴(6) (6a)를 지면에서 떨어지게 하고 지면에 닿은 타측뒷바퀴(7)를 돌려서 축지부(2)를 기점으로 자동차의 앞쪽을 타측뒷바퀴(7)의 회전방향으로 회전하게 하였다. 그리고 축지부(2)는 유압피스턴축(8a)하단에 축지판(9)이 공회전하게 유설되었으며, 전, 후면에 지지편(8b)이 있는 유압실린더(8)의 상단에 플랜지(10)가 죠인트(11)로 축설되어져서 플랜지(10)를 “U”보울트(12)에 나사불이 기하면 축지부(2)를 간단히 설치할 수 있고 다른 유압실린더(13)단부를 액슬클립(14′)에 축설하며 유압피스턴축(13a)단부를 유압실린더(8)하부에 축설하여 축지부(2)를 차체 하부쪽으로 오무렸다가 필요에 따라 뒤액슬 직하방으로 직립되게 펼칠 수 있도록 하였고 안내바퀴(4)는 유압실린더(14)외면에 돌설된 지지편(2a)에 축설하여 유압피스턴(14a)상단에 축설된 플랜지(15)에서 앞액슬 중앙부 하면에 “U”보울트(16)로 고정하고 다른 유압실리던 (17)단부는 플랜지(15)일측면에 축설하며, 피스턴축(17a)단부는 유압실린더 (14)일측에 축설하여 안내바퀴(4)를 앞액슬하면쪽으로 오무렸다가 필요에 따라 직하방으로 직립되게 펼 수 있도록 하였다. 그리고 각 유압실린더는 적당한 공지방법의 유압시스템에 의하여 운전석에서 작동할 수 있도록 하였다.Since the wheels are laid out at the front, rear axle, left and right, and the wheels are in contact with the ground, if you want to rotate the car in the desired direction, lift the body so that the wheels are off the ground, There is no. However, it is not easy to lift the car body so that the wheels fall off the ground, and even if it is lifted up, the device for lifting a heavy car body is thought to be impossible to achieve without the complicated device. In consideration of these problems, the simplest and safest way was conceived, and as a result, one side of the rear axle housing was lifted so that the wheels could be lifted from the ground, and the front wheels were turned from the ground, and the back axle was lifted from the ground. If you turn the other wheel in contact, the front of the car will rotate left and right in the same direction as the other wheel's rotation direction.The guide wheel will be installed at right angles to the center line of the wheel to naturally rotate the car body in place. The present invention has been made possible according to the accompanying drawings. Described in detail as follows. An axle portion 2 is installed at one lower side of the rear axle housing 1 of the vehicle, and a guide wheel 4 is installed at right angles to the center line A of the axle portion 2 at the center lower portion of the front axle 3. The wheels (5) and the front wheels (6) (6a) off the ground, and turn the other rear wheel (7) on the ground to turn the front of the car on the other side of the rear wheel (7). It was made to rotate in the direction of rotation. And the bearing portion (2) is installed on the lower end of the hydraulic piston shaft (8a) the bearing plate (9) idling, the flange 10 on the upper end of the hydraulic cylinder (8) having the support piece (8b) in the front, rear When the flange 10 is screwed into the “U” bolt 12, it can be easily installed, and the other hydraulic cylinder 13 end is axle clip 14 '. And the hydraulic piston shaft (13a) at the lower end of the hydraulic cylinder (8) to squeeze the bearing part (2) toward the lower part of the vehicle body and to extend it upright under the rear axle as necessary. Is installed on the support piece 2a protruding from the outer side of the hydraulic cylinder 14, and is fixed to the “U” bolt 16 on the lower surface of the front axle at the flange 15 formed on the upper side of the hydraulic piston 14a. The end portion 17 of the dun 17 is arranged on one side of the flange 15, and the end portion of the piston shaft 17a is formed on one side of the hydraulic cylinder 14. If the front axle and the wheel (4) were to be presented ohmuryeotda expand the erection necessary to direct toward the room. And each hydraulic cylinder was able to operate in the driver's seat by the appropriate well-known hydraulic system.

이와같은 본 발명은 운전석에서 유압시스템을 조작하여 제4도에서와 같이 축지부(2)를 뒤액슬하우징(1)의 직하방으로 직립시켜서 축지판(9)을 지면에 닿게 다음 축지부측 차바퀴(5)가 지면에서 돌리게 함과 동시 제3도에서와 같이 안내바퀴 (4)를 앞액슬(3) 직하방에서 직립시켜 앞쪽 양바퀴(7)를 지면에서 떨어지게 들어올리면 뒤액슬의 타측뒷바퀴(7)는 지면에 닿고 축지부축 차바퀴(5)와 앞쪽양바퀴 (6)는 지면에서 떨어지게 되므로 이러한 상태에서 자동차엔진의 시동력으로 타측뒷바퀴(7)를 회전시키면 타측뒷바퀴(7)의 회전방향과 동일한 방향으로 차앞쪽이 제1도에서와 같이 방향을 바꾸므로 자동차를 제자리에서 임의의 방향으로 360도 회전시킬수 있다. 그리고 축지부축 차바퀴(5)만 옆쪽으로 이동시킬 수 있으면 자동차를 옆으로 지그자그형으로 이동시킬 수도 있다. 이와같이 본 발명은 지극히 간편하고 안전한 방법으로 자동차를 제자리에서 임의의 방향으로 회전시킬 수 있기 때문에 협소하고 복잡한 주차장에서도 자동차를 자유로히 붙혀서 주차하거나 빼낼 수 있고 자동차를 되도려 운전할 수도 있다.The present invention operates the hydraulic system in the driver's seat so that the bearing portion 2 is erected directly under the rear axle housing 1 as shown in FIG. 4 so that the bearing plate 9 touches the ground. (5) is turned from the ground and at the same time, as shown in FIG. 3, the guide wheel (4) is erected directly under the front axle (3), and the front wheels (7) are lifted off the ground and the other rear wheel ( 7) is in contact with the ground, and the wheel axle shaft (5) and the front both wheels (6) fall off the ground, so if you rotate the other rear wheel (7) with the starting force of the automobile engine in this state and the direction of rotation of the other rear wheel (7) In the same direction, the front of the car changes direction as shown in FIG. And if only the wheel-wheel shaft 5 can be moved to the side, the car can also be moved to the side in a zigzag shape. As described above, the present invention can rotate the vehicle in place in an extremely simple and safe manner in any direction, so that even in a narrow and complicated parking lot, the vehicle can be freely attached or parked or removed, and the vehicle can be driven back.
