차량용 스티어링 휠 진동 시험장치 { Vibration testing machine for steering wheel of vehicle }Vibration testing machine for steering wheel of vehicle}

본 발명은 스티어링 휠에서 발생되는 진동을 측정하기 위한 진동 측정장치에 관한 것으로서, 보다 상세하게는 실차상태와 동일한 조건으로 제작된 시험지그를 사용하여 시험을 실시함으로써, 카울 크로스 멤버와 스티어링 칼럼의 개발기간을 단축하고, 스티어링 휠의 진동에 따른 개선작업을 효율적을 실시할 수 있는 차량용 스티이링 진동 시험장치에 관한 것이다.The present invention relates to a vibration measuring device for measuring the vibration generated from the steering wheel, and more particularly, by performing a test using a test jig manufactured under the same conditions as the actual vehicle state, the development period of the cowl cross member and the steering column The present invention relates to a vehicle steering vibration test apparatus capable of shortening and efficiently performing improvement work according to vibration of a steering wheel.

일반적으로 차량용 조향장치는 자동차의 진행방향을 임의로 바꾸기 위해 조향하는 장치로서, 운전석에 설치되어 운전자가 조작하는 스티어링 휠과, 이 스티어링 휠에 연결되어 조향력을 전달하는 스티어링 칼럼과, 이 스티어링 칼럼과 연결되어 스티어링 칼럼의 회전에 따라 바퀴의 방향을 움직이는 스티어링 기어 등으로 이루어진다.Generally, a steering device for a vehicle is a steering device for arbitrarily changing a driving direction of a vehicle. A steering wheel installed in a driver's seat and operated by a driver, a steering column connected to the steering wheel to transmit steering power, and connected to the steering column It is made of a steering gear and the like to move the direction of the wheel according to the rotation of the steering column.

여기에서, 스티어링 칼럼은 스티어링 휠의 조작력을 스티어링 기어에 전달하는 축으로, 그 일측은 카울 크로스 멤버에 회전 가능하게 지지된다.Here, the steering column is an axis for transmitting the operating force of the steering wheel to the steering gear, one side of which is rotatably supported by the cowl cross member.

이러한 스티어링 휠의 진동을 측정하는 장치는 스티어링 휠의 단일품에 대한 고유진동수 개발만으로는 실차에 스티어링 휠을 장착한 후 발생되는 진동을 예측하기 어렵기 때문에 실차에 스티어링 휠이 장착된 상태에서 스티어링 휠의 진동 시험을 실시한다.Such a device for measuring the vibration of the steering wheel is difficult to predict vibration generated after the steering wheel is mounted on the actual vehicle only by developing a natural frequency of a single part of the steering wheel. Perform a vibration test.

그러나, 상기한 바와 같은 종래기술에 따른 스티어링 휠의 진동시험은 스티어링 휠을 실차에 장착한 상태에서 스티어링 휠의 진동 시험이 실시되기 때문에 실차상태에서 스티어링 휠의 진동에 따른 카울 크로스 멤버의 개선작업이 불가능하기 때문에 개발시험이 어려운 문제점이 있다.However, the vibration test of the steering wheel according to the prior art as described above, because the vibration test of the steering wheel is carried out with the steering wheel mounted on the vehicle, the improvement of the cowl cross member according to the vibration of the steering wheel in the actual vehicle state Development test is difficult because it is impossible.

또한, 카울 크로스 멤버의 보강사양에 따른 시험이 불가능하여 실차에 대해 용접에 의한 보강작업, 보강용 스테이 추가 등의 방법으로 개발이 이루어지기 때문에 체계적인 개발시험이 실시되지 못하는 문제점이 있다.In addition, since the test is not possible according to the reinforcement specification of the cowl cross member, the development is carried out by a method such as reinforcement work by welding or reinforcement stay for the actual vehicle, so that a systematic development test cannot be performed.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 별도의 시험용 지그를 제작하여 카울 크로스 멤버를 마운팅하고, 이 카울 크로스 멤버에 실차와 동일한 조건으로 스티어링 휠을 장착하여 진동 시험을 실시함으로써, 시험기간을 단축할 수 있고, 카울 크로스 멤버의 개선 작업을 보다 용이하게 실시할 수 있는 차량용 스티어링 휠 진동 시험장치를 제공하는 데 있다.The present invention was created to solve the above problems, an object of the present invention is to manufacture a separate test jig to mount the cowl cross member, and to mount the steering wheel to the cowl cross member under the same conditions as the actual vehicle vibration test The present invention provides a vehicle steering wheel vibration tester that can shorten a test period and more easily perform a cowl cross member improvement work.

도 1은 본 발명에 따른 차량용 스티어링 휠 진동 시험장치의 구성도이다.1 is a configuration diagram of a vehicle steering wheel vibration tester according to the present invention.

스티어링 휠 진동 시험장치는 카울 크로스 멤버(2)가 수평하게 장착되는 카울 크로스 멤버 지지대(4)와, 카울 크로스 멤버(2)의 일측에 회전 가능하게 장착되는 스티어링 칼럼(6)과, 이 스티어링 칼럼(6)의 상측에 연결되는 스티어링 휠(8)과, 베이스(10)의 하측에 장착되어 스티어링 칼럼(6)의 일측을 지지하는 스티어링 칼럼 지지대(12)와, 스티어링 칼럼(6)의 하측에 연결되어 스티어링 칼럼(6)에 진동을 발생시키는 진동 발생기(14)와, 상기 스티어링 휠(8)의 일측에 부착되어 스티어링 휠(8)의 진동 정도를 검출하는 진동센서(16) 등으로 이루어진다.The steering wheel vibration test apparatus includes a cowl cross member support 4 on which the cowl cross member 2 is horizontally mounted, a steering column 6 rotatably mounted on one side of the cowl cross member 2, and the steering column. A steering wheel 8 connected to the upper side of the 6, a steering column support 12 mounted to the lower side of the base 10 to support one side of the steering column 6, and a lower side of the steering column 6. And a vibration generator 14 connected to generate a vibration in the steering column 6 and a vibration sensor 16 attached to one side of the steering wheel 8 to detect a vibration degree of the steering wheel 8.

카울 크로스 멤버 지지대(4)는 카울 크로스 멤버(2)의 양쪽 끝부분이 수평하게 장착되도록 카울 크로스 멤버(2)의 길이에 맞는 간격을 두고 베이스(10)에서 수직방향으로 세워진다.The cowl cross member support 4 is erected in the vertical direction at the base 10 at intervals matching the length of the cowl cross member 2 such that both ends of the cowl cross member 2 are mounted horizontally.

카울 크로스 멤버(6)는 실차에 장착되는 것과 동일한 구조를 갖는 것으로, 양쪽 끝부분은 실차에 장착되는 것과 동일한 조건으로 카울 크로스 멤버 지지대(4)에 장착된다.The cowl cross member 6 has the same structure as that mounted on the vehicle, and both ends are mounted to the cowl cross member support 4 under the same conditions as the vehicle is mounted on the vehicle.

스티어링 칼럼(6)은 상단에 스티어링 휠(8)이 장착되고, 하단에는 진동발생기(14)가 장착되는 실차에 장착되는 상태와 동일한 조건으로 일정 각도로 경사지게 설치되며, 상부 일측은 카울 크로스 멤버(2)의 일측에 장착되고, 하부 일측은 스티어링 칼럼 지지대(12)에 장착된다.The steering column 6 is mounted to the steering wheel 8 at the upper end, the lower end is inclined at a predetermined angle under the same conditions as the state mounted on the actual vehicle in which the vibration generator 14 is mounted, the upper one side is a cowl cross member ( 2) is mounted on one side, the lower one side is mounted to the steering column support (12).

스티어링 칼럼 지지대(12)는 베이스(10)의 일측에서 수직으로 세워진 상태로 스티어링 칼럼(6)의 하부 일측을 지지한다.The steering column support 12 supports the lower one side of the steering column 6 in a state of standing vertically at one side of the base 10.

진동 발생기(14)는 RPM에 따라 진폭이 가변되는 일반적인 구조의 진동 발생기가 사용된다.The vibration generator 14 is a vibration generator of a general structure in which the amplitude is changed according to the RPM.

이와 같이 이루어진 차량용 스티어링 휠 진동 시험장치의 작용을 다음에서 설명한다.The operation of the vehicle steering wheel vibration tester made as described above will be described below.

먼저, 시험하고자 하는 차종의 카울 크로스 멤버(2)의 양쪽 끝부분을 카울 크로스 멤버 지지대(4)에 장착한다. 그리고, 스티어링 휠(8)이 부착되는 스티어링 칼럼(6)을 실차에서와 동일하게 경사각을 갖도록 카울 크로스 멤버(2)의 일측에 장착하고, 하부 일측은 스티어링 칼럼 지지대(12)에 장착한다. 그리고, 스티어링 칼럼(6)의 끝부분을 진동 발생기(14)에 부착시킨다.First, both ends of the cowl cross member 2 of the vehicle model to be tested are mounted on the cowl cross member support 4. The steering column 6 to which the steering wheel 8 is attached is mounted on one side of the cowl cross member 2 so as to have an inclination angle as in the vehicle, and the lower one side is mounted on the steering column support 12. Then, the end of the steering column 6 is attached to the vibration generator 14.

이러한 상태에서, 진동 발생기(14)를 설정된 RPM으로 회전시키면 스티어링 칼럼(6)을 통해 스티어링 휠(8)로 진동이 전달된다. 이때, 스티어링 휠(8)에 부착된 진동센서(16)에서 진동 정도를 검출하여 스티어링 휠(8)에서 발생되는 진동을 측정한다.In this state, when the vibration generator 14 is rotated at the set RPM, vibration is transmitted to the steering wheel 8 through the steering column 6. At this time, the vibration degree is detected by the vibration sensor 16 attached to the steering wheel 8 to measure the vibration generated from the steering wheel (8).

이러한 과정을 반복하여 얻은 개선된 스티어링 칼럼과 카울 크로스 멤버와 초기 제작된 것과 비교하여 개선 시험을 반복 실시한다.The improvement test is repeated with the improved steering column and cowl cross member obtained from the repeated procedure and with the original one.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 차량용 스티어링 칼럼 진동 시험장치는 실차의 조건과 동일한 상태로 스티어링 칼럼과 카울 크로스 멤버를 별도의 시험용 지그에 설치하고, 진동 발생기의 진동으로 스티어링 휠에서 발생되는 진동을 측정함으로써, 스티어링 휠의 진동이 실차가 아닌 시험지그에서 이루어지기 때문에 카울 크로스 멤버와 스티어링 칼럼의 개발 기간을 단축시킬 수 있고, 진동 시험이 용이하게 실시할 수 있는 이점이 있다.Therefore, the steering column vibration test apparatus for a vehicle according to the present invention configured and operated as described above is provided with the steering column and the cowl cross member in a separate test jig in the same condition as the actual vehicle, and the vibration of the vibration generator in the steering wheel By measuring the vibration generated, since the vibration of the steering wheel is made in the test jig rather than the actual vehicle, it is possible to shorten the development period of the cowl cross member and the steering column, and to perform the vibration test easily.
