Description

운반차의 동력전달방법 및 차동장치{METHOD OF TRANSMITTING POWER AND DIFFERENTIAL GEAR FOR VEHICLE}METHOD OF TRANSMITTING POWER AND DIFFERENTIAL GEAR FOR VEHICLE}

본 발명은 주로 로폭(路幅)이 좁거나 이동거리나 한정되어 있는 작업장내에서 비교적 부피가 적고 상대적으로 무거운 적재물을 간편하게 적재운반할수 있는 운반차에 관한 것으로 특히 충전용 감속 모우터의 구동력으로 회전하는 양차륜의 회전비(匯傳比)를 차동조절 되도록 함과 동시에 구동력을 차단시킨 상태에서도 운반차를 수동으로 밀거나 끌 수 있도록 구성한 운반차의 동력전달방법 및 차동장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a transport vehicle that can easily carry relatively small and relatively heavy loads in a workplace where the width is narrow or the travel distance is limited. In particular, the invention relates to a driving force of a charging reduction motor. The present invention relates to a power transmission method and a differential apparatus of a vehicle configured to manually push or pull a vehicle even when the driving force is cut off while allowing the rotation ratio of both wheels to be differentially controlled.

종래에도 이와 같이 중량의 소형 적재물을 운반하기 위해 간단한 구조의 모우터를 장착하고 이를 체인으로 차륜축에 연결하여 작동되게 한 구성의 운반차가 출현된 바 있다.Conventionally, a carrier of a configuration in which a motor having a simple structure and a chain is connected to a wheel shaft by a chain and is operated to carry a small load of weight as described above has been introduced.

그러나 이러한 구성의 운반차는 모우터로 부터 전달되는 구동력이 양차륜에 동률의 회전비로 전달되기 때문에 운반차를 운전하는 중 코너부를 회전할 때는 자칫 운반차가 전복되는 경우가 허다하였고 더욱이 동력전달에 이상이 발생하여 운반차가 움직이지 아니할 때 작업자가 직접 수동으로 운반차를 밀거나 끌 수 있도록 한 별도의 장치도 마련되어 있지 아니하여 운반작업에 많은 어려움과 불편을 초래하는 문제점이 있어왔다.본 발명의 목적은 운반자의 양쪽차륜으로 전달되는 감속모우터의 구동력을 차동조절되게 함과 동시에 고장시 감속모우터가 정지한 상태에서도 운반차를 수동으로 움직일 수 있도록 양쪽차륜축을 각각 구비한 차동기어 케이스를 밋션부의 내부로 결합 구성하여 차륜의 회전비에 따라 차륜축으로 전달되는 구동력을 차동시켜 운반차의 운행을 안전히 함과 동시에 차륜축으로 전달되는 구동력을 클러치레버로 간편하게 조작시켜 전달 차단할 수 있도록 하므로서 운반차의 이동수단을 작업자가 임의로 조작실시(동력 및 수동)하여 운반차을 이용한 이동작업을 편리하게 한 운반차의 동력전달방법 및 차동장치를 제공하려는 것이다.However, in this configuration, the driving force transmitted from the motor is transmitted to both wheels at the same rate of rotation, so when the corner is rotated while driving the vehicle, the vehicle is often overturned. There is a problem that causes a lot of difficulties and inconveniences in the transport operation because there is no separate device that allows the operator to manually push or turn off the transport vehicle when it does not move. The differential gear case is provided with both wheel shafts so that the driving force of the deceleration motor transmitted to both wheels of the carrier can be differentially adjusted and the vehicle can be moved manually even when the deceleration motor is stopped in case of failure. Differentiate the driving force transmitted to the wheel shaft according to the rotation ratio of the wheel The operator can operate the vehicle's moving means arbitrarily (power and manual) to make it possible to cut off the driving force transmitted to the wheel axle by simply operating the clutch lever with the clutch lever. It is to provide a power transmission method and a differential device for a vehicle that makes it convenient.

본 발명은 상기와 같은 종래의 문제점을 해소하고 목적달성에 현저한 효과를 구현할 수 있는 운반차를 제공함에 있어 운바차의 차륜축으로 모우터의 구동력이 전달되는 방법을 클러치레버의 조작에 따라 변속기어와 치합되는 디퍼렌셜기어에 의해 밋련부내에서 회전하는 차동 케이스의 내부에 서로 치합하여 반대방향으로 회전하는 디퍼렌셜(Differential Helicalgear)에 각각의 차륜축 헬리컬기어를 치합구성시켜 모우터의 구동력이 동일한 회전비로 차륜에 전달되도록 하고 또한 변속기어를 클러치레버의 조작으로 디퍼렌셜기어로 부터 격리(隔離)시켜주면 모우터의 구동력이 차동되면서 차륜축이 공회전됨에 따라 고장시는 물론 작업자가 임의로 스위치의 " 온 " " 오프 " 및 클레치 레버를 선택적으로 조작하여 운반차를 동력 및 수동으로 실시할 수 있고 특히 차륜축으로 전달시켜 주는 구동력의 전달매체(傳達媒體)를 헬리컬기어로 이루워지게 한 운반차의 동력전달방법 및 차동장치를 특징으로 한다.The present invention is to solve the conventional problems as described above and to provide a vehicle that can implement a remarkable effect on the achievement of a method of transmitting the driving force of the motor to the wheel shaft of the wheel wheel according to the operation of the transmission gear and the clutch lever. Each wheel axle helical gear is assembled to differential wheels that rotate in opposite directions by engaging each other inside the differential case that rotates in the connection part by the differential gears that are engaged with each other. In addition, if the transmission gear is isolated from the differential gear by the operation of the clutch lever, the driving force of the motor is differential and the wheel axle is idling. And the clutch lever can be selectively operated to power and manually In particular, the present invention is characterized by a power transmission method and a differential device of a transport vehicle in which a transmission medium for driving force transmitted to a wheel axle is formed by a helical gear.

이와 같이 구성된 본 발명의 작동을 상세히 설명한다.적재물을 운반차(15)의 바닥판(13)상에 적재하고 작업자가 핸들부(10)에 취부된 스위치(SW)을 " 온 " 하면 밧데리(도시생략)의 전원으로 작동하는 감속모우터(M)의 구동력이 차륜(14)(14')에 동일한 회전비(匯傳比)로 전달되어 운반차(15)가 비교적 안전한 속도록 움직이게 되고 또 스위치(SW)을 " 오프 " 하여 구동력을 정지시킨 상태에서는 클러치레버(27)을 조작하여 운반차(15)을 수동으로 밀거나 끌 수 있도록 구성되어 있어서 주로 로폭(路幅)이 좁거나 이동거리를 한정하고 있는 작업장내에서 적재물의 운반수단으로 편리하게 사용된다.이렇게 사용되는 본 발명의 운반차(15)을 감속모우터(M)의 구동력으로 이동시킬 때는 핸들부(10)에 취부된 스위치(SW)을 " 온 " 시켜주면 상기 감속모우터(M)의 헬리컬기어(22)가 회전함에 따라 이와 맞물려 있는 클러치축기어(23)에 끼움 고정된 헬리컬기어(22')에 구동력이 전달되므로 클러축기어(23)가 회전을 한다.상기의 클러치축기어(23)에는 스프링(28)의 신장력으로 밀려 클러치축기어(23)에 끼움되어 있는 또다른 변속기어(23')가 차동기어 케이스(24)의 디퍼렌셜기어(25)와 맞물려진 상태에서 구동력이 상기의 디퍼렌셜기어(25)로 전달되고 이렇게 전달된 구동력은 차동기어 케이스(24)의 내부로 치합구성되어 있는 한쌍의 디퍼렌셜 헬리컬기어(26)(26')에 의해 차륜축(21)(21')의 헬리컬기어(21a)(21a')로 각각 전달되므로 차륜(14)(14')에 균등한 구동력이 제공되는 것이며 또 운반차(15)를 수동으로 밀거나 끌고저 할 때는 스위치(SW)을 " 오프 " 시킨다.그러면 감속 모우터(M)의 정지로 인해 차륜(14)(14')이 공회전(이후설명)되므로 운반차(15)을 작업자가 적은 힘으로 끌거나 밀수있어서 운반작업의 용이성은 물론 특히 동력수단으로 운반작업을 하다가 갑자기 고장이 발생할 경우에도 스위치(SW)의" 오프 " 하여 수동으로 운반작업을 계속 실시할 수 있기 때문에 수리센터로의 이동도 용이하게 하는 것으로 이를 좀더 상세히 설명하면 도 5a도에서 보는 바와 같이 클러치축기어(23)에 끼움되어 있는 변속기어(23')을 상기의 클러치레버(27)로 회동조작시켜주면 도 5b도에서 보는 바와 같이 변속기어(23)에 걸려끼움된 변속레버축(28)이 클러치레버(27)에 연결핀(27')으로 끼움 연결된 상태에서 연결핀(27)이 클러치레버(27)의 기치홈(27a)에서 거치턱(27b)으로 이동함에 따라 변속기어(23')는 클러치축기어(23)에서 수축작용과 더불어 이동하면서 차동기어 케이스(24)의 디퍼렌셜기어(25)가 격리되므로 운반차(15)를 수동으로 밀거나 끌때 일어나는 차륜(14)(14')의 회전력이 변속기어(23')로 전달되지 않기 때문에 차륜(14)(14')의 회전력을 비교적 가볍고 부드럽게 하므로 운반차(15)의 이동을 적은 힘으로 손쉽게 실시할 수 있는 것이다.그리고 수동에서 다시 동력을 이용하고저 할 때는 클러치레버(27)을 다시 회동 조작시켜 원위치로 풀어주게되면 거치턱(27b)으로 이동되어 있던 연결핀(27')이 거치홈(27a)으로 안내되면서 스프링(29)의 신장력으로 변속 레버축(28)과 같이 변속기어(23')가 차동기어 케이스(24)의 디퍼렌셜기어(25)와 치합하는것에 의해 다시 구동력이 차륜(14)(14')으로 전달되므로 운반차를 수동에서 동력으로의 전환이 용이하고 특히 적재물을 적재 운반할때도 커브길에서 전복되지 않도록 차륜(14)(14')의 회전력을 차동기어 케이스(24)에 디퍼렌셜기어(25)와 디퍼렌셜헬리컬기(26)(26') 및 헬리컬기어(21a)(21a')로 치합구성된 것에 의해 용이하게 달성될 수 있게 되는 것이다.The operation of the present invention configured as described above will be described in detail. When the load is loaded on the bottom plate 13 of the transport vehicle 15 and the operator "on" the switch SW mounted on the handle part 10, the battery ( The driving force of the deceleration motor M, which is operated by the power source of the drawing, is transmitted to the wheels 14 and 14 'at the same rotation ratio, so that the carriage 15 moves at a relatively safe speed and switches In the state where the driving force is stopped by turning off the SW, the clutch lever 27 is operated so that the vehicle 15 can be manually pushed or turned off, so that the road width is narrow or the travel distance is mainly reduced. It is conveniently used as a conveying means of a load in a limited workplace. When the conveying vehicle 15 of the present invention used in this way is driven by the driving force of the reduction motor M, a switch mounted on the handle portion 10 ( When SW) is turned on, the helical gear 22 of the reduction motor M is As the driving force is transmitted to the helical gear 22 'fixed to the clutch shaft gear 23 engaged with the rotating shaft, the claw shaft gear 23 rotates. The clutch shaft gear 23 has a spring 28; The differential gear 25 is driven in a state where another transmission gear 23 'fitted to the clutch shaft gear 23 is engaged with the differential gear 25 of the differential gear case 24 by being pushed by the extension force of And the driving force transmitted to the helical gear 21a of the wheel shafts 21 and 21 'by the pair of differential helical gears 26 and 26' which are engaged with the inside of the differential gear case 24. It is transmitted to each of the wheels 21a ', so that an equal driving force is provided to the wheels 14 and 14', and the switch SW is "off" when the vehicle 15 is pushed or pulled manually. Since the wheels 14 and 14 'are idling (described later) due to the stop of the reduction motor M, the vehicle 15 is stopped. Since the worker can drag or push with a small force, it is easy to carry out the transport work as well as the transport work can be carried out manually by "off" the switch (SW) even in the event of a sudden breakdown during transport work by power means. It will also be easy to move to the center to be described in more detail as shown in Figure 5a when the transmission gear 23 'fitted to the clutch shaft gear 23 is rotated by the clutch lever 27 As shown in FIG. 5B, the coupling pin 27 is connected to the clutch lever 27 in a state in which the shift lever shaft 28 fitted to the transmission gear 23 is connected to the clutch lever 27 by a connecting pin 27 '. As the shift gear 23 'moves along with the contraction action in the clutch shaft gear 23, the differential gear 25 of the differential gear case 24 is moved as the shift groove 23a moves from the banner groove 27a of To isolate the carrier (15) Since the rotational force of the wheels 14 and 14 ', which occurs when pushing or dragging manually, is not transmitted to the transmission gear 23', the rotational force of the wheels 14 and 14 'is relatively light and smooth, so that the movement of the carriage 15 is carried out. It can be easily carried out with a small force. And when using the power again from the manual, when the clutch lever 27 is rotated again to release to the original position, the connecting pin (27) moved to the mounting jaw (27b) ') Is guided to the mounting groove (27a) by the transmission gear 23' is engaged with the differential gear (25) of the differential gear case (24) like the shift lever shaft (28) by the extension force of the spring (29). In addition, the driving force is transmitted to the wheels 14 and 14 'so that it is easy to switch the vehicle from manual to power, and in particular, the rotational force of the wheels 14 and 14' is prevented from being overturned on the curve even when carrying loads. Differential gear (25) and differential in the differential gear case (24) It can be easily achieved by engaging with the helical gears 26 and 26 'and the helical gears 21a and 21a'.

이상에서 설명한바와 같이 본 발명의 운반하는 로폭이 좁은 도로나 또는 커브길 및 적재물을 운반 이동시킬때 발생할 수 있는 고장 등에 안전과 편의성을 제공할 수 있도록 변속기어로 부터 차동기어 케이스의 디퍼렌셜기로 전달되는 구동을 차동 및 전달하기 위한 클러치레버와; 상기 차동기어 케이스의 양쪽 차륜축을 각각의 디퍼렌셜 헬리컬기어로 치합구성하므로서 종래의 운반차가 갖고 있는 기어방식의 구동력 전달방법에서 오는 경제성과 안전성 및 반영구성을 보다 향상시켜 제공하는 효과가 있게 되는 것이다.As described above, the drive is transmitted from the transmission gear to the differential gear case differential to provide safety and convenience, such as narrow roadways or curved roads and breakdowns that may occur when carrying loads. A clutch lever for differentially transmitting the clutch; By forming both wheel shafts of the differential gear case with the respective differential helical gears, the economical efficiency, safety, and reflection configuration that come from the transmission method of the driving method of the gear system of the conventional transport vehicle are improved.
