본 고안은 오일펌프를 구동하여 차량의 신속한 조향조작을 할수 있도록 한 자동차용 조향장치에 관한 것으로서 특히 조향장치의 기어부유격을 스프링 보조장치로 감소키켜 고속중립주행시 바퀴의 떨림을 방지하여 주행안정성을 도모할 수 있도록 한 자동차용 조향장치의 유격감소구조에 관한 것이다.The present invention relates to a steering device for an automobile that enables a quick steering operation of a vehicle by driving an oil pump. In particular, the gear clearance of the steering device is reduced by a spring assist device, thereby preventing the shaking of the wheel during high-speed neutral driving. It relates to a play reduction structure of a vehicle steering device that can be achieved.
일반적으로 자동차는 가볍고 신속한 조항을 하기 위하여 동력조향장치를 사용하여 기곤으로는 오일펌프를 구동하여 발생한 유압으로 중앙에 설치된 랙크피스톤에 보내어 랙크피스톤의 작동으로 조향핸들의 조작력을 부드럽게 하였던것은 주지된 사실이다.In general, it is well known that automobiles use a power steering device to make light and quick provisions, which are driven by an oil pump and sent to a centrally installed rack piston, which smoothes the steering wheel's operation by operating the rack piston. to be.
그러나 종래의 자동차용 조향장치는 제3도에서와 같이 하우징(51)내부의 가이도봉(52)에 랙크기어(54)를 갖는 랙크피스톤(53)을 볼베어링이 압입된 상태로 축설하되 그 타측에는 제어밸브(55)를 설치하고, 랙크기어(54)와는 섹터기어(56)를 맞물린 상태로 조립하여 구성되었다.However, in the conventional automobile steering apparatus, as shown in FIG. 3, a rack piston 53 having a rack gear 54 is installed on the guide rod 52 inside the housing 51 with the ball bearing pressed therein, The control valve 55 was installed, and the rack gear 54 and the sector gear 56 were assembled together with each other.
이와 같은 종래의 조향장치 작동은 조향핸들 조작의 비틀림에 따라 제어밸브(55)에 공급되는 오일을 제어밸브(55)에서 전환하여 볼베어링이 압입된 랙크피스톤(53)을 가이드봉(52)상에서 이동시키는 것이다.In the conventional steering device operation, the oil supplied to the control valve 55 is switched from the control valve 55 according to the twisting of the steering wheel operation to move the rack piston 53 in which the ball bearing is press-fitted on the guide rod 52. It is to let.
이때 상기 랙크피스톤(53)의 이동방향에 따라 랙크기어(54)와 치합된 섹터기어(56)를 좌,우로 회전시켜 자동차 조향방향을 설정토록 하는 것이다.At this time, according to the movement direction of the rack piston 53, the sector gear 56 meshed with the rack gear 54 is rotated left and right to set the steering direction of the vehicle.
그러므로 상기와 같이 구성된 조향장치는 단순히 랙크기어(54)와 섹터기어(56)가 맞물린 상태로만 조립되어있어 고속중립주행시 기어의 맞물려 치합고정됨 이 중앙에는 어느정도 유격이 없는 반면 기어의 양측에는 유격발생이 많이 발생되어 바퀴떨림의 발생으로 주행안정성이 떨어지게되는 문제점등이 야기되었다.Therefore, the steering device configured as described above is assembled only with the rack gear 54 and the sector gear 56 engaged, so that the gear is engaged with the gear during high-speed neutral driving. There is no play at this center, but there is play at both sides of the gear. The occurrence of wheel shake caused a lot of problems such as running stability is reduced.
본 고안은 상기한 종래의 제문제점등을 해결하기 위하여 안출된 것으로서, 본 고안의 그 주된 목적은 하우징내에 섹터기어와 맞물려 조립된 랙크피스톤의 타측에 스프링력을 갖는 지지봉을 조립하여 상기 지지봉이 랙크피스톤을 향상 밀어 섹터기어와 랙크기어를 긴밀히 맞물리도록하여 고속주행시 랙크기어와 맞물린 섹터기어의 유동됨을 방지하여 주행시 안전하고 쾌적한 주행성을 향상시키고자 함이 그특징이다.The present invention has been made to solve the above-mentioned problems, the main purpose of the present invention is to assemble the support rod having a spring force on the other side of the rack piston assembled in engagement with the sector gear in the housing and the support rod rack Its feature is to improve the safe and comfortable driving performance by driving the pistons so that the sector gears and the rack gears are closely engaged to prevent the flow of the sector gears engaged with the rack gears at high speeds.
상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의하여 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 정면도이고, 제2도는 본 고안의 조향장치 측면도이다.1 is a front view of a steering apparatus to which the present invention is applied, and FIG. 2 is a side view of the steering apparatus of the present invention.
제1도 및 제2도에서와 같이 하우징(1)내부의 가이드봉(2)에 랙크기어(4)가 일체로 가공된 랙크피스톤(3)을 설치한다.As shown in FIG. 1 and FIG. 2, the rack piston 3, in which the rack gear 4 is integrally processed, is installed on the guide rod 2 inside the housing 1. As shown in FIG.
그리고 상기 랙크피스톤(3)의 타측에는 유압을 제어할 수 있는 제어밸브(5)를 설치하고, 랙크기어(4)에는 섹터기어(6)를 치합한다.The other side of the rack piston 3 is provided with a control valve 5 capable of controlling the hydraulic pressure, and the rack gear 4 is fitted with the sector gear 6.
그리고 상기 랙크피스톤(3) 일측에는 호형요입홈(7)을 가공하고, 호형요입홈(7)의 대응되는 위치의 하우징(1)에는 스프링(9)이 탄설된 지지봉(10)을 삽입설치한 유격제어부(8)를 나사식결합하여 랙크피스톤(3)을 항상 구속하도록 구성되었다.And one side of the rack piston (3) is machined arc-shaped indentation groove (7), and the housing (1) of the corresponding position of the arc-shaped indentation groove (7) is inserted into the support rod 10 is installed in the spring (9) The play control part 8 was screwed to the rack piston 3.
이와 같이 구성된 본 고안의 동력조향장치는 조향핸들의 조작시 조향핸들 조작의 비틀림에 따라 하우징(1)내에 설치된 제어밸브(5)에 공급되는 오일을 전환하여 볼베어링이 압입된 랙크피스톤(3)을 가이드봉(2)에서 축방향으로 이송됨에 따라 랙크기어(4)에 치합된 섹터기어(6)를 회전시켜 운전자가 선택한 진행방향으로 회전시킨다.The power steering apparatus of the present invention configured as described above converts the oil supplied to the control valve 5 installed in the housing 1 according to the twisting of the steering wheel operation when the steering wheel is operated, thereby causing the rack piston 3 to which the ball bearing is press-fitted. As the guide rod 2 is moved in the axial direction, the sector gear 6 engaged with the rack size gear 4 is rotated to rotate in the direction selected by the driver.
그러면 본 고안의 조향장치는 제어밸브(5)에 공급되는 오일량에 의해 가이드봉(2)에서 축방향으로 이송작동되는 랙크피스톤(3)이 색터기어(6)를 조작완료한 후 자동차가 중립고속주행시에는 하우징(1)에 나사식 결합된 유격제어부(8)의 지지봉(10)이 스프링(9)의 스프링력을 받아 항시 전진상태로 랙크피스톤(3)을 누르고있는 상태가 된다.Then, the steering device of the present invention is the vehicle neutral after the rack piston (3) operated to transfer the axial direction from the guide rod (2) by the amount of oil supplied to the control valve (5) During high speed driving, the support rod 10 of the play control part 8 screwed to the housing 1 is pressed against the rack piston 3 at all times by the spring force of the spring 9.
이때 스프링(9)의 스프링력에 의해 구속된 랙크피스톤(3)을 밀고있으므로서 랙크피스톤(3)과 일체된 랙크기어(4)와 섹터기어(6)는 항상 긴밀히 치합된 상태로 유격이 보정되게 치합되는 것이다.At this time, while pushing the rack piston (3) restrained by the spring force of the spring (9), the rack gear (4) and the sector gear (6) integrated with the rack piston (3) is always closely in close contact with the play clearance It's very tight.
그러므로 자동차의 고속중립주행시 랙크피스톤(3)이 지지봉(10)에 항상 구속되어 섹터기어(6)의 고정이 확실하여 바퀴떨림현상을 방지하게 되는 것이다.Therefore, during the high speed neutral driving of the vehicle, the rack piston 3 is always restrained by the support rod 10 so that the fixing of the sector gear 6 is secured, thereby preventing wheel shaking.
이상설명한 바와 같이 조향장치의 하우징내에 설치된 랙크피스톤에 호형요입홈을 형성하고 이와 대응되는 위치의 하우징에는 스프링을 삽입된 지지봉이 일체로된 유격제어부를 나사식 설치하여 자동차의 고속중립주행시 상기 유격제어부의 지지봉이 스프링력에 의해 랙크피스톤을 지지하므로서 랙크피스톤의 랙크기어와 섹터기어간의 유격을 항시 보상하고 있는 것으로서 바퀴등을 떨림을 방지하여 주행안정성을 가일층 도모 할 수 있는 매우 유용한 고안이다.As described above, the arc control groove is formed in the rack piston installed in the housing of the steering apparatus, and the clearance control part is integrally installed with the support rod in which the spring is inserted into the housing at the corresponding position. As the support rod supports the rack piston by the spring force, it always compensates for the gap between the rack gear of the rack piston and the sector gear. It is a very useful design that can further improve driving stability by preventing the wheels from shaking.
