본 고안은 오일펌프를 구동하여 차량의 신속한 조향조작을 하기 위한 자동차용 조향장치에 관한 것으로서, 특히 고속중립주행에서 바퀴의 떨림을 방지하여 주행안전성을 도모하기 위한 자동차용 조향장치의 떨림방지장치에 관한 것이다.The present invention relates to a steering device for a vehicle for driving a steering wheel of a vehicle by operating an oil pump, in particular, to the anti-shake device of a steering device for a vehicle for preventing driving of wheels in high speed neutral driving to promote driving safety. It is about.
일반적으로 자동차는 가볍고 시속한 조향을 위해 동력조향장치를 사용하며 기관으로 오일펌프를 구동하여 발생한 유압을 조향장치의 중앙에 설치된 랙크피스톤에 보내에랙크피스톤의 작동으로 핸들의 조작력을 가볍게 하는 것은 주지의 사실이다.In general, automobiles use a power steering system for light and timely steering, and it is well known that the hydraulic pressure generated by driving the oil pump to the engine is sent to the rack pistons installed in the center of the steering system to lighten the steering force of the steering wheel by the operation of the rack pistons. Is true.
그러나 종래의 자동차용 조향장치는 제2도에서와 같이 하우징(51)내부의 가이드봉(52)에 랙크기어(54)를 갖는 랙크피스톤(53)을 볼베어링이 압입한 상태로 축설하되 그 타측에는 제어밸브(55)를 설치하고 랙크기어(54)와는 섹터기어(56)를 맞물린 상태로 설치하여 구성되었다.However, in the conventional automotive steering apparatus, as shown in FIG. 2, the rack piston piston 53 having the rack gear 54 is mounted on the guide rod 52 inside the housing 51 with the ball bearing pressed in the other side. The control valve 55 was installed, and the rack gear 54 and the sector gear 56 were engaged with each other.
이와 같은 종래의 조향장치의 작동을 조향핸들 조작의 비틀림에 따라 제어밸브(55)에 공급되는 오일을 제어밸브(55)에서 전환하여 볼베어링이 압입된 랙크피스톤(53)을 가이드봉(52)상에서 이동시키는 것인데 이때 릭크피스톤(53)의 이동방향에 따라 랙크기어(54)와 치합된 섹터기어(56)를 좌, 우로 회전시켜 자동차 진행을 설정토록하였다.The operation of the conventional steering device is switched to the oil supplied to the control valve 55 according to the twisting of the steering wheel operation, and the control valve 55 switches the rack piston piston 53 into which the ball bearing is press-fitted. In this case, the sector gear 56 engaged with the rack gear 54 is rotated to the left and the right according to the moving direction of the rick piston 53 to set the driving of the vehicle.
그러나 상기와 같이 구성되었을 시에는 단순히 랙크기어(54)의 섹터기어(56)가 맞물린 상태로만 되어 있어 고속중앙주행시에는 기어의 맞물려 고정됨이 정확치 않아 바퀴떨림에 위해 주행 안전성이 떨어지는 문제점등이 야기되었다.However, when configured as described above, the sector gears 56 of the rack gear 54 are simply engaged with each other, so that the gears are not fixed to each other during high-speed center driving. .
본 고안은 상기한 종래의 제문제점등을 해결하기 위한 것으로서 본 발명의 그 목적은 하우징내의 가이드봉에서 오일의 제어량에 따라 이동조정되는 랙크기어가 형성된 랙크피스톤을 스프링력을 갖는 핀에 의해 지지토록하여 고속주행시 랙크기어와 맞물린 섹터기어를 견고히 고정된 상태로 고정하여 안전하고 쾌적한 주행을 도모하고저한 것이 그 특징이다.The object of the present invention is to solve the above-mentioned problems. The object of the present invention is to support a rack piston formed with a spring gear which is moved and adjusted in accordance with a control amount of oil in a guide rod in a housing by a pin having spring force. Therefore, the high-speed driving is securely and comfortably secured by fixing the sector gear meshed with the rack gear in a fixed state.
상기한 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의해 상세히 설명하면 다음과 같다.When the present invention to achieve the above object will be described in detail by the accompanying drawings as follows.
제1도는 본 고안이 적용된 조향장치의 개략 정단면도이다.1 is a schematic front sectional view of a steering apparatus to which the present invention is applied.
도면에서와 같이 하우징(1)내부의 가이드봉(2)에 랙크기어(4)가 일체로 형성된 랙크피스톤(3)을 설치하되 그 타측에는 제어밸브(5)를 설치하고 상기 랙크기어(4)에는 섹터기어(6)를 치합된 상태로 설치한 조향장치에 있어서, 상기 랙크피스톤(3) 일측에는 걸림지지홈(3a)를 일체로 형성하고 걸림지지홈(3a)와 대응되는 위치의 하우징(1)에는 스프링(7)이 탄설된 상태로 핀(8)을 설치하여 중립고속주행시 주행안전성을도모할 수 있도록 구성된 것이다.As shown in the drawing, a rack piston (3) in which the rack gear (4) is integrally installed on the guide rod (2) inside the housing (1) is installed, while the control valve (5) is installed on the other side of the rack gear (4). In the steering apparatus in which the sector gear 6 is engaged with each other, the rack support piston 3 has a housing having a locking support groove 3a integrally formed at one side thereof and corresponding to the locking support groove 3a. 1) In the state that the spring (7) is installed in the pinned state to install the pin (8) it is configured to promote driving safety during neutral high-speed driving.
이와 같이 구성된 본 고안의 구동은 조향핸들 조작의 비틀림에 따라 제어밸브(5)에 공급되는 오일을 절환하여 볼베어링이 압입된 랙크피스톤(3)을 가이드봉(2)에서 이송됨에 따라 랙크기어(4)가 섹터기어(6)를 회전시킨다.According to the driving of the present invention configured as described above, as the oil supplied to the control valve 5 is switched according to the twisting of the steering wheel operation, the rack piston (3) in which the ball bearing is press-fitted is transferred from the guide rod (2). ) Rotates the sector gear 6.
이때 랙크피스톤(3)이 조작완료후 중립고속주행시에는 하우징(1)에 설치된 핀(8)이 스프링(7)의 스프링력을 받아 항시 전진상태로 되다가 랙크피스톤(3)에 형성된 걸림지지홈(3a)에 도달하면 스프링력을 받은 핀(8)은 걸림지지홈(3a)에 걸려 지지된 상태로 랙크피스톤(3)을 누르고 있으므로 섹터기어(6)의 고정이 확실하여 바퀴떨림현상을 방지하게 되는 것이다.At this time, when the high speed neutral driving after the operation of the rack piston 3 is completed, the pin 8 installed in the housing 1 is always moved forward under the spring force of the spring 7, and the locking support groove formed on the rack piston 3 When 3a) is reached, the pin 8, which is spring-loaded, presses the rack piston 3 while being held in the latching support groove 3a, so that the sector gear 6 is securely fixed to prevent the wheels from shaking. Will be.
이상 설명한 바와 같이 하우징내에 설치된 랙크피스톤에 걸림지지홈을 일체로 형성하고 걸림지지홈 대응위치에 스프링이 탄설된 핀을 설치하여 고속중립주행시 상기 핀이 스프링력에 의해 랙크피스톤을 지지하므로서 바퀴등의 떨림을 방지하여 주행안전성을 가일층 도모할 수 있는 매우 유용한 고안이다.As described above, the locking support grooves are integrally formed in the rack pistons installed in the housing, and spring-loaded pins are installed in the corresponding positions of the locking support grooves so that the pins support the rack pistons by spring force during high speed neutral driving. It is a very useful design that can further improve driving safety by preventing shaking.
