본 발명은 롤테스트용 정속주행장치에 관한 것으로, 보다 상세하게는 롤테스트 시 악셀페달을 일정한 힘으로 가압하여 테스트 차량의 속도를 일정하게 유지하기 위한 장치에 관한 것이다.The present invention relates to a constant speed driving apparatus for a roll test, and more particularly, to a device for maintaining a constant speed of a test vehicle by pressing the axel pedal with a constant force during a roll test.

일반적으로 조립이 완성된 차량은 보안 기준상의 완성차 검사 항목에 따라 자동차 기능검사를 수행하게 되는데 하자가 발견되면 수정작업을 한다.In general, the assembled vehicle performs the functional inspection of the vehicle according to the inspection criteria of the completed vehicle in the security standards.

검사 항목에는 헤드램프 에이밍, 휠얼라인먼트, 브레이크 테스트, 롤테스트(ROLL TEST), 사이드슬립 체크 등이 있는데, 이 중 롤테스트는, 차량의 앞바퀴를 롤테스터에 얹혀 두고 일반운전자가 도로주행을 할 때 필요한 모든 장치(계기판, 에어콘, 히터 등등)를 확인검사하고 가속력과 기어 변속상의 문제점, 엔진의 소음 등을 테스트하는 것을 말한다.The inspection items include headlamp aming, wheel alignment, brake test, roll test, and side slip check. Among these, the roll test includes the front wheel of the vehicle mounted on the roll tester and the general driver This is to check and check all necessary equipment (dashboards, air conditioners, heaters, etc.) and to test the acceleration, gear shifting problems and engine noise.

이러한 롤테스트 시 각종 시험에 필요한 속도를 유지하기 위하여 악셀패달을 일정하게 밟고 있어야 하는데, 도1에 도시된 바와 같이, 종래에는 이를 사람이 직접수행하여야 했다. 그러나, 정속주행 테스트는 2∼3 시간 정도 소요되기도 하는 바, 작업자의 무릎 통증을 유발할 뿐만 아니라 테스트 시간 냉내 일정속도를 유지하는 것이 사실상 어려운 문제점이 있었다. 도1에서 도면부호 1, 2는 각각 악셀패달과 브레이크패달을 지칭한다.In this roll test, in order to maintain the speed necessary for various tests, the accelerator pedal must be constantly stepped on, as shown in FIG. However, the constant speed test may take about 2 to 3 hours, not only causing the knee pain of the operator, but also maintaining a constant speed during the test time has a problem in fact difficult. In Fig. 1, reference numerals 1 and 2 refer to axel pedals and brake pedals, respectively.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것으로, 롤테스트 시 악 셀페달을 일정한 힘으로 가압하여 테스트 차량의 속도를 일정하게 유지하기 위한 정속주행장치를 제공함을 목적으로 한다.The present invention has been proposed to solve this problem, and an object of the present invention is to provide a constant speed driving apparatus for maintaining a constant speed of a test vehicle by pressing the axel pedal with a constant force during roll testing.

상기의 목적을 달성하기 위한 본 발명에 따른 롤테스트용 정속주행장치는 전기모터에 의해 축회전하는 피니언가 설치된 기어박스; 기어박스를 관통하여 설치되며, 피니언에 맞물려 피니언 구동시 상하방향으로 이동가능한 랙; 및 기어박스 일측에 마련되며, 랙의 일단이 악셀페달의 상면에 놓여질 수 있도록, 테스트 차량의 브레이크패달에 고정되는 지그:를 포함하는 것을 특징으로 한다.Rolling test for constant speed driving apparatus according to the present invention for achieving the above object is a gear box is installed with a pinion axial rotation by an electric motor; A rack installed through the gearbox and engaged with the pinion and movable up and down when the pinion is driven; And a jig: provided at one side of the gearbox and fixed to the brake pedal of the test vehicle so that one end of the rack may be placed on the upper surface of the accelerator pedal.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 롤테스트용 정속주행장치에 대하여 살펴본다.Hereinafter, with reference to the accompanying drawings looks at the constant speed driving apparatus for a roll test according to an embodiment of the present invention.

도2 및 도5에서 볼 수 있는 바와 같이, 정속주행장치는 크게 보아 악셀패달(1)의 상면을 일정한 힘으로 가압하기 위한 랙(20)이 설치된 기어박스(10)와, 기어박스(10)를 브레이크패달(2)에 고정하기 위한 지그(40)로 구성된다.As can be seen in Figures 2 and 5, the cruise control device is a large gear box 10 and the gear box 10 is installed, the rack 20 for pressing the upper surface of the axel pedal (1) with a constant force, large view It consists of a jig 40 for fixing to the brake pedal (2).

기어박스(10)의 내부에는, 도4에서 볼 수 있는 바와 같이, 전기모터(14)에 의해 축회전(11)되는 피니언(12)과, 이 피니언(12)이 회전에 따라 상하방향으로 이동하는 랙(21)를 가이드하기 위한 가이드(13)가 설치되어 있다. 피니언(12)과 랙(20)의 치(齒)가 서로 맞물릴 수 있도록, 가이드(13)의 피니언(12) 측 부위는 개방되어 있다.Inside the gearbox 10, as shown in FIG. 4, the pinion 12 is axially rotated by the electric motor 14, and the pinion 12 is moved up and down in accordance with the rotation. A guide 13 for guiding the rack 21 is provided. The pinion 12 side portion of the guide 13 is open so that the pinions 12 and the teeth of the rack 20 can be engaged with each other.

랙(20)은, 도2 및 도4에서 볼 수 있는 바와 같이, 기어박스(10)를 상향방향으로 관통하여 설치되어 있어, 그 길이방향을 따라 형성된 치(21)에 맞물린 피니 언(12)이 정방향 혹은 역방향으로 회전함에 따라, 상방향 혹은 하방향으로 이동된다. 이러한 랙(20)의 양단(20a, 20b)은 모두 기어박스(10) 외부로 노출되어 있는데, 이는 기어박스(10)를 어느 방향으로 고정하더라도 랙(20)을 이용하여 악셀패달(1)을 가압할 수 있도록 하기 위함이다. 즉, 도5에 도시된 정속주행장치의 경우 랙 하단(20b)이 악셀패달(1)을 가압하고 있으나, 도5에 도시된 정속주행장치를 거꾸로 고정하는 경우에는 랙 상단(20a)이 악셀패달(1)을 가압할 수 있다. 이와 같이, 랙(20)의 양단을 모두 기어박스(10) 외부로 노출시킬 것인지 혹은 어느 한 단부만 노출시킬지는 단순히 선택에 달린 문제이나, 사용상의 간편함을 위하여는 랙(20) 양단이 모두 기어박스(10) 외부로 노출되는 것이 보다 바람직하다. 랙(20)의 양단(20a, 20b)에는 악셀패달(1)의 보호를 위해 보호커버를 씌울 수 있다.As can be seen in FIGS. 2 and 4, the rack 20 penetrates the gearbox 10 in an upward direction and is engaged with the pinion 12 engaged with the teeth 21 formed along the longitudinal direction thereof. As it rotates in the forward or reverse direction, it moves upward or downward. Both ends 20a and 20b of the rack 20 are exposed to the outside of the gearbox 10, which is fixed to the gearbox 10 in any direction by using the rack 20 to access the axel pedals 1. This is to allow pressurization. That is, in the case of the cruise control shown in FIG. 5, the rack bottom 20b is pressing the axel pedal 1, but in the case of fixing the cruise control shown in FIG. 5 upside down, the rack top 20a is the axel pedal. (1) can be pressurized. As such, whether both ends of the rack 20 are exposed to the outside of the gearbox 10 or only one end thereof is a matter of choice, but both ends of the rack 20 are geared for ease of use. More preferably exposed outside the box 10. Both ends 20a and 20b of the rack 20 may be covered with a protective cover to protect the axel pedal 1.

한편, 기어박스(10)의 상면에는, 도3에서 볼 수 있는 바와 같이, 랙(20)이 이동한 거리 내지 악셀패달(1)이 가압된 정도를 표시하기 위한 디스플레이부(3)와, 랙(20)의 이동거리를 조절하기 위한 조절부(4)가 마련된다.On the other hand, as shown in Figure 3, the upper surface of the gear box 10, the display unit 3 for displaying the distance the rack 20 is moved to the degree of pressing the accelerator pedal 1 and the rack, The adjusting unit 4 for adjusting the moving distance of the 20 is provided.

지그(40)는, 도2 및 도5에서 볼 수 있는 바와 같이, 브레이크패달(2)을 사이에 끼울 수 있도록 서로 대향배치된 고정턱(30a, 30b)을 구비한다. 통상적인 기술에 따라, 고정턱 중 어느 일측의 턱은 이동가능하여 고정턱 사이의 공간(31)에 놓여진 브레이크패달(2)이 죔고정되도록 할 수 있으나, 비용경제적인 측면을 고려한다면, 고정턱(30a, 30b)의 어느 일측에 이동로드(40)를 설치하여 이동로드(40)를 상하방향으로 이동시킴에 의해 고정턱 사이의 공간(31)에 배치된 브레이크패달(2)을 죔고정하는 것이 보다 바람직하다. As can be seen in FIGS. 2 and 5, the jig 40 has fixing jaws 30a and 30b disposed to face each other so as to sandwich the brake pedal 2 therebetween. According to the conventional technique, the jaw on either side of the fixed jaw is movable to allow the brake pedal 2 placed in the space 31 between the fixed jaws to be fastened, but considering the cost-effective aspect, the fixed jaw By installing the moving rod 40 on either side of the 30a, 30b to move the moving rod 40 in the up and down direction to fasten the brake pedal 2 disposed in the space 31 between the fixed jaws It is more preferable.

이동로드(40)의 상단(40a)은 이동로드(40)의 조작을 편리하게 하기 위하여 사각구조를 갖는게 좋으며, 하단(40b)은 악셀패달(2)을 견고하게 고정할 수 있도록 그 바닥면이 넓은 것이 좋다. 이동로드(40)의 하단(40b)에는 악셀패달(2)의 보호를 위해 보호커버가 씌워질 수 있다.The upper end 40a of the movable rod 40 may have a rectangular structure for convenient operation of the movable rod 40, and the lower end 40b of the movable rod 40 may firmly fix the axel pedal 2. This is a good thing. The lower end 40b of the movable rod 40 may be covered with a protective cover for protecting the axel pedal 2.

한편, 상부 고정턱(30a)을 관통하여 설치된 이동로드(40)의 이동은, 고정턱(30a)에 나사결합되도록 하여 이동로드(40)의 상단(40a)을 회전시킴에 의해 이루어지도록 할 수 있다.On the other hand, the movement of the moving rod 40 installed through the upper fixing jaw (30a), it can be made by rotating the upper end (40a) of the moving rod 40 by screwing to the fixing jaw (30a). have.

상술한 바와 같은 구조로 이루어진 롤테스트용 정속주행장치에 따르면, 기계적인 작동에 의해 악셀패달을 일정한 힘으로 가압할 수 있으므로, 사람이 악셀패달을 2∼3 시간 밟고 있어야 함에 따라 발생되는 각종 문제가 방지될 수 있다.According to the roll test cruise control device having the above-described structure, since the axel pedal can be pressurized with a certain force by mechanical operation, various problems arising as a person has to step on the axel pedal for 2 to 3 hours Can be prevented.

또한, 장치가 크기 않고 그 구조가 단순하므로, 제조비용이 낮으며 사용하기 편리하다.In addition, since the apparatus is not large and its structure is simple, the manufacturing cost is low and it is convenient to use.
