Description

자동차의 토크 스티어 방지방법How to prevent torque steer of a car

본 발명은 자동차의 토크 스티어 방지방법에 관한 것으로서, 보다 상세하게는 조인트 샤프트를 사용하지 않고 토크 스티어를 방지함으로써 구조가 간단하고 생산원가를 절감할 수 있는 자동차의 토크 스티어 방지방법에 관한 것이다.The present invention relates to a method for preventing a torque steer of an automobile, and more particularly, to a method for preventing a torque steer of an automobile, in which a structure is simple and a production cost can be reduced by preventing a torque steer without using a joint shaft.

자동차의 동력전달장치는 엔진에서 발생된 동력을 구동바퀴에 전달하기 위한 장치로 클러치, 변속기, 추진축, 종감속기어, 차동장치, 액슬 샤프트 등으로 구성된다.The power transmission device of a vehicle is a device for transmitting power generated from an engine to a driving wheel, and is composed of a clutch, a transmission, a propulsion shaft, a reduction gear, a differential, an axle shaft, and the like.

한편 FF(Front Engine Front Drive)차량과 RR(Rear Engine Rear Drive)차량에서는 엔진과 변속기가 구동륜 근처에 있어, 액슬과 변속기가 일체로 되어 있는 것이 편리하며, 이러한 것을 트랜스 액슬(Trans axle)이라고 한다.On the other hand, FF (Front Engine Front Drive) and RR (Rear Engine Rear Drive) vehicles have an engine and a transmission near the driving wheel, so it is convenient to have an axle and a transmission integrated. This is called a trans axle. .

FR(Front Engine Rear Drive)차량에서도 엔진으로부터 트랜스미션을 분리하여 후륜의 파이널드라이브에 트랜스미션을 일체화하여 전후의 중량배분을 좋게한 자동차도 있다.In some vehicles, the front engine rear drive (FR) also separates the transmission from the engine and integrates the transmission into the rear final drive to improve the weight distribution.

종래 FF차량의 동력전달장치를 도 1을 참조하여 설명하면 다음과 같다.A power transmission device of a conventional FF vehicle will be described with reference to FIG. 1.

엔진(10)에는 트랜스 액슬(12)이 결합되며, 상기 트랜스 액슬(12)은 등속 조인트(22)로 좌우측 드라이브 샤프트(16, 18)와 결합되며, 상기 드라이브 샤프트(16, 18)는 액슬 샤프트(24)와 등속조인트(20)로 결합된다.A transaxle 12 is coupled to the engine 10, and the transaxle 12 is coupled to the left and right drive shafts 16 and 18 by a constant velocity joint 22, and the drive shafts 16 and 18 are axle shafts. (24) and the constant velocity joint (20).

이때 액슬 샤프트(24)쪽의 등속조인트(20)구조가 간단하고 용량이 큰 버필드 조인트(birfield joint)가 통상 사용된다.At this time, a birfield joint having a simple structure having a large constant velocity joint 20 on the axle shaft 24 is commonly used.

한편 FF차량에서는 드라이브 샤프트(16, 18)가 시작하는 트랜스 액슬(12)의 드라이브 센터(C)가 차량의 중심에서 왼쪽 또는 오른쪽으로 위치하므로 좌우 드라이브 샤프트(16, 18)의 길이가 상이한 비등장형이 되는 것이 보통이다.On the other hand, in the FF vehicle, the drive center C of the transaxle 12 where the drive shafts 16 and 18 start is located left or right from the center of the vehicle, so that the left and right drive shafts 16 and 18 have different lengths. It is common to become

이러한 경우에 좌측의 조인트 절각(B1)과 우측의 조인트 절각(B2)은 다르고 좌우측의 캠버각(A1, A2)은 같은 상태가 된다.In this case, the joint joint B1 on the left side and the joint joint B2 on the right side are different, and the camber angles A1 and A2 on the left and right sides are in the same state.

이에 따라 절각(B1, B2)의 차이에 의하여 짝힘이 발생하고, 이 짝힘에 의해서 토크 스터어 현상이 발생한다.As a result, a pairing occurs due to the difference between the incidences B1 and B2, and a torque stir phenomenon occurs due to the pairing.

즉 급가속시에는 절각이 작은 쪽으로 차량이 쏠리고 반대로 급감속시에는 절각이 큰 쪽으로 차량이 쏠리기 때문에 급가속 및 급감속시에는 운전자가 핸들에 힘을 가하지 않고 있으면 사고의 위험이 있다.In other words, when the acceleration is accelerated, the vehicle is inclined toward the smaller angle, and in the case of the rapid deceleration, the vehicle is inclined at the larger angle.

따라서 도 2에 도시한 바와 같이, 좌우 드라이브 샤프트(16, 18)의 사이에 조인트 샤프트(2)를 추가해서 등장형으로 만듬으로써 토크 스티어 현상을 방지하고 있다.Therefore, as shown in FIG. 2, the torque steering phenomenon is prevented by adding the joint shaft 2 between the left and right drive shafts 16 and 18 and making it isotonic.

그러나 앞에서 설명한 종래의 자동차의 토크 스티어 방지방법에서는 조인트 샤프트를 이용하므로 비용이 많이 들고 또한 구조가 복잡하다는 문제점이 있었다.However, in the conventional method for preventing the torque steer of a vehicle described above, a joint shaft is used, which causes a high cost and a complicated structure.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서 본 발명의 목적은 구조가 간단하며 비용이 저렴한 자동차의 토크 스티어 방지방법을 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for preventing a torque steer of an automobile having a simple structure and low cost.

상기 목적을 달성하기 위한 본 발명의 구성을 설명하면 다음과 같다.Referring to the configuration of the present invention for achieving the above object is as follows.

본 발명의 특징은 좌우측 드라이브 샤프트의 절각이 동일해지록 절각 차이를 휠의 캠버각에서 보정하여 주는 데에 있다.It is a feature of the present invention to correct the difference in the angle of camber of the wheel so that the angles of left and right drive shafts are the same.

즉 본 발명에 따른 자동차의 토크 스티어 방지방법는 좌우측 절각이 동일하도록 좌우측 캠버각을 조정하는 단계를 포함하여 이루어진다.That is, the method of preventing a torque steer of an automobile according to the present invention includes adjusting the left and right camber angles so that the left and right side joints are the same.

이하 상기의 목적을 구체적으로 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면를 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

본 실시예에서 종래기술과 동일한 구성은 동일 명칭 및 동일 부호를 병기하며 그에 대한 설명은 생략한다.In the present embodiment, the same configuration as the prior art has the same name and the same reference numerals and description thereof will be omitted.

도 3을 참조하여 본 발명에 따른 자동차의 토크 스티어 방지방법을 설명하면 다음과 같다.Referring to Figure 3 describes a torque steer prevention method of a vehicle according to the present invention.

좌측 절각(B1)과 우측 절각(B2)이 같도록 좌측 캠버각(A1)과 우측 캠버각(A2)을 조절한다.The left camber angle A1 and the right camber angle A2 are adjusted such that the left angle B1 and the right angle B2 are equal.

이때 좌측 절각(B1)과 우측 절각(B2)은 같게 하면 당연히 좌측 캠버각(A1)과 우측 캠버각(A2)은 달라지게 된다.At this time, if the left angle B1 and the right angle B2 are the same, the left camber angle A1 and the right camber angle A2 are different.

이렇게 하면 비등장형 드라이브 샤프트에서 조인트 샤프트를 사용하지 않고도 좌우측 캠버각(A1, A2)을 조절함으로써 간단히 좌우측 절각(B1, B2)을 동일하게 할 수가 있다,This makes it possible to equalize the left and right notches B1 and B2 simply by adjusting the left and right camber angles A1 and A2 without using the joint shaft in the non-driven drive shaft.

따라서 좌우측 절각(B1, B2)이 동일하므로 절각 차이로 인한 토크 스티어 현상이 방지된다.Therefore, since the left and right angles B1 and B2 are the same, the torque steer phenomenon due to the difference in angles is prevented.

상기에서 설명한 본 발명에 따른 실시예의 효과를 설명하면 다음과 같다.Referring to the effects of the embodiment according to the present invention described above are as follows.

위에서 설명한 본 발명에 의하면, 조인트 샤프트를 사용하지 않고 토크 스티어 현상을 방지할 수 있으므로 드라이브 라인이 간단해지고 또한 생산성이 향상된다는 이점이 있다.According to the present invention described above, the torque steer phenomenon can be prevented without using the joint shaft, so that the drive line is simplified and the productivity is improved.

상기에서 본 발명은 하나의 실시예만을 설명하였으나, 첨부된 청구범위에서 알 수 있는 바와 같이 본 발명이 속한 분야의 통상의 지식을 가진자는 본 발명의 정신을 벗어나지 않고 변형이 가능하고 이러한 변형은 본 발명의 범위에 속한다는 것을 이해할 것이다.The present invention has been described above only one embodiment, but as can be seen in the appended claims, those skilled in the art to which the present invention pertains may be modified without departing from the spirit of the present invention. It will be understood that it belongs to the scope of the invention.
