Description

양방향 조향장치가 구비된 차량{vehicle equipped with a bi-directional steering system}Vehicle equipped with a bi-directional steering system

본 발명은 전류과 후륜이 모두 조향 가능한 구조로 이루어짐으로써 주행편의성이 향상되는 차량에 관한 것이다.The present invention relates to a vehicle in which driving convenience is improved by having a structure in which both current and rear wheels can be steered.

일반적으로 차량의 조향장치는 전륜과 연결된 랙피니언 기어와 이에 연결된 조향축과, 조향축에 구비된 조향핸들로 이루어진다.(랙 피니언 방식)In general, a steering device of a vehicle consists of a rack and pinion gear connected to a front wheel, a steering shaft connected thereto, and a steering wheel provided on the steering shaft (rack and pinion method).

운전자는 조향핸들을 조작하여 전륜의 각도를 조절함으로써 차량의 나아가는 방향을 변경하게 되며, 근래에는 조향핸들의 조작편의성을 위한 유압식, 전기모터식 등의 다양한 방식이 사용되고 있다.The driver controls the angle of the front wheel by manipulating the steering wheel to change the traveling direction of the vehicle, and in recent years, various methods such as hydraulic type and electric motor type are used for the convenience of operating the steering wheel.

차량의 조향장치는 전륜을 제어하는 방식으로 이루어지기 때문에, 좁은 골목길이나 주차장과 같이 선회가 어렵거나 불가능한 조건에서 불가피하게 후진으로 주행하여야 하는 경우에는 신속하고 정확한 방향제어가 어려워서 사고발생 위험이 높다는 문제점이 있었다.Since the steering system of a vehicle is made by controlling the front wheels, it is difficult to quickly and accurately control the direction when it is unavoidable to drive backward in conditions where it is difficult or impossible to turn, such as a narrow alley or a parking lot, so the risk of accidents is high. there was

이는 운전자가 인지하는 주행감각이 앞을 보는 방향으로만 정확하게 인식되어지며, 후진하는 경우에는 방향감각이 제대로 작용하지 않기 때문이다.This is because the driving sense perceived by the driver is accurately recognized only in the direction of looking ahead, and the sense of direction does not work properly when reversing.

한편, 내연기관 엔진을 사용한 차량의 구동방식은 엔진과 구동륜과의 연결에 따라 전륜구동식, 후륜구동식, 4륜 구동식 등으로 다양하게 이루어질 수 있으나, 조향장치는 오로지 차량의 전륜에 대해서만 구성되었다. On the other hand, the driving method of a vehicle using an internal combustion engine engine may be variously made into a front wheel drive type, a rear wheel drive type, a 4 wheel drive type, etc. depending on the connection between the engine and the driving wheels, but the steering system is configured only for the front wheel of the vehicle became

이는 내연기관 엔진의 특성상, 엔진에서 발생하는 동력을 차륜에 전달하기 위해서는 동력전달장치 및 변속기어 등의 복잡한 구성이 필요하기 때문에 차량이 전후양방향으로 동일한 주행이 가능토록 하기 위해서는 구조적으로 많은 어려움이 있기 때문이다.This is due to the characteristics of the internal combustion engine engine, since a complex configuration such as a power transmission device and transmission gear is required to transmit the power generated from the engine to the wheels.

In the driving direction selection system, for example, when a user presses a driving direction selection button (not shown) provided on the front dashboard 30 and the rear dashboard 40 of the vehicle, the steering wheel in the selected direction is usable. , and the driver's seat 50, 52, 54 may be automatically rotated in a selected direction.

상술한 바와 같이 구성된 본 발명에 따른 차량의 기능에 대하여 설명하면 다음과 같다.The function of the vehicle according to the present invention configured as described above will be described as follows.

우선, 본 발명에 따르면, 전륜(100)과 후륜(200)에 대하여 각각 전륜조향장치(10)와 후륜조향장치(20)가 갖추어져 있기 때문에 운전자의 의도 내지는 운전조건에 따라서 전륜조향장치(10)와 후륜조향장치(20)를 선택적으로 사용할 수 있다.First, according to the present invention, since the front wheel steering device 10 and the rear wheel steering device 20 are respectively provided for the front wheel 100 and the rear wheel 200, the front wheel steering device 10 according to the driver's intention or driving conditions. and the rear wheel steering device 20 may be selectively used.

따라서, 전륜조향장치(10)를 사용하여 전진하다가 더 이상 전진이 불가하고, 선회 또한 어려운 상황에 처하게 되면, 후륜조향장치(20)를 사용하여 편하게 후진으로 주행할 수 있게 된다. Therefore, when moving forward using the front wheel steering device 10 and it is impossible to move forward any more and turning is also difficult, it is possible to comfortably drive backward using the rear wheel steering device 20 .

또한, 종래에는, 차량이 전면으로 주차된 상태에서는, 차량을 주차위치에서 빼내기 위하여 일정거리 만큼 후진하여야 했으나, 본 발명에 의하면 후륜조향장치(20)를 사용하여 운전함으로써 후진이 아니라 전진하는 방식으로 차량을 쉽게 빼낼 수 있게 된다.In addition, in the prior art, in a state in which the vehicle is parked in the front, the vehicle had to be reversed by a certain distance in order to take it out of the parking position. The vehicle can be easily removed.

여기서, 예시적으로 전륜조향장치(10)를 사용하다가 후륜조향장치(20)로 바꾸어 사용할게 되면, 후륜조향장치(20)를 사용할 수 있도록 운전석시트(50)(52)(54)의 앉는 방향을 변경하게 된다.(도 3, 도 4 참조)Here, when the front wheel steering device 10 is used for example and the rear wheel steering device 20 is changed to be used, the seating direction of the driver's seat 50, 52, and 54 so that the rear wheel steering device 20 can be used. is changed. (See FIGS. 3 and 4)

그리고, 사용하고자 하는 후륜조향장치(20)가 선택된 다음에는, 사용되지 않는 전륜조향장치(10)의 전륜조향핸들(12)이 전방 대시보드(30) 안으로 들어가게 됨으로써 탑승자의 승하차시 불편이 덜하도록 함과 동시에 차내 공간의 활용도가 높아지도록 한다.And, after the rear wheel steering device 20 to be used is selected, the front wheel steering handle 12 of the front wheel steering device 10, which is not used, is moved into the front dashboard 30 so as to reduce inconvenience to passengers when getting on and off. At the same time, the utilization of the space in the vehicle is increased.

주행방향 선택시스템이 갖추어진 경우에는 전술한 바와 같이 운전자가 주행방향 선택버튼을 누름으로써 원하는 방향의 조향장치를 사용할 수 있는 상태로 해당 운전석시트와 해당 조향핸들이 자동으로 전환된다.When the driving direction selection system is equipped, the driver's seat and the corresponding steering wheel are automatically switched to a state in which the driver can use the steering device in the desired direction by pressing the driving direction selection button as described above.

이와 같이 본 발명에 의하면, 운전자의 선택에 따라 전륜조향장치(10) 또는 후륜조향장치(30)를 선택적으로 사용함으로써 차량의 전진 후진의 구분이 없이 편리하게 주행할 수 있게 된다.As described above, according to the present invention, by selectively using the front wheel steering device 10 or the rear wheel steering device 30 according to the driver's choice, it is possible to conveniently drive the vehicle without distinction between forward and reverse.
