The end of the torsion pipe is connected to a connecting pipe(40), and the end of the connecting pipe is fixed in an anchor bracket. The torsion pipe is integrally connected to the connecting pipe with engagement. Torsion reaction force is transmitted to the torsion pipe in twisting the torsion bar, and torsion is increased without extending the length of the torsion bar.

Description

차량용 토션 바Torsion bar for vehicle

본 발명은 차량용 토션 바에 관한 것으로, 특히 로어 암등의 비틀림력을 강성에 의해 원상태로 복귀시키기 위한 토션 바의 외주연에 토션 파이프를 설치하여 상기 토션 바의 길이를 늘이지 않고 높은 비틀림력을 얻을 수 있도록 한 차량용 토션 바에 관한 것이다.The present invention relates to a torsion bar for a vehicle. In particular, a torsion pipe is installed on the outer circumference of a torsion bar for returning a twisting force of a lower arm to an original state by rigidity so as to obtain a high torsion force without increasing the length of the torsion bar. The present invention relates to a torsion bar for a vehicle.

일반적으로, 자동차의 현가장치에 사용되는 토션 바(Torsion bar)는 도 1에 나타낸 바와같이, 스프링강의 막대를 고정된 앵커 브라켓트(1)와 로어아암(2) 사이에 설치되어 이 로어아암(2)의 작동에 의해 어느 정도 비틀림력이 생성된 후 원 상태로 복귀되는 성질을 갖는다.In general, a torsion bar used in a suspension apparatus of an automobile is provided between a fixed anchor bracket 1 and a lower arm 2 so that a rod of a spring steel is fixed to the lower arm 2 ), And then returns to the original state after the twisting force is generated to some extent.

상기 토션 바(10)의 비틀림력은 길이, 단면적에 의해 정해지며, 단위중량당 에너지 흡수율이 다른 스프링에 비해 크기 때문에 경량이면서 구조도 간단히 할 수가 있다.The torsional force of the torsion bar 10 is determined by the length and the cross-sectional area, and since the energy absorption rate per unit weight is larger than that of the other springs, the twist force of the torsion bar 10 can be lightweight and simple in structure.

그의 배치방법으로는 차체에 평행하게 놓는 세로식(종치식)과 직각으로 놓는 가로 놓임식(횡치식)이 있으며, 세로 놓임식은 토션 바의 길이의 제약을 받지 않치만 장치하는 데 장소를 차지하지 않는 등의 이점이 있으며, 토션 바로서는 단면형상이 원형의 것이 일반적이지만, 평판모양의 스프링을 겹쳐 단면을 직사각형으로 만든것도 있다.There are a longitudinal type (longitudinal type) which is placed parallel to the body and a lateral type (vertical type) which is placed at a right angle. The vertical type is not restricted by the length of the torsion bar, And the torsion bar is generally circular in cross section, but it is also possible to make a rectangular cross section by overlapping flat spring.

상기 토션바 중 도 2에 나타낸 바와같이 단면이 원형인 토션 바(10)는 외주면을 감싸도록 파이프(20)가 설치되며 이들은 일단이 톱니 혹은 육각형상으로 연결되어 단순히 토션 바(10)를 비틀어주는 역할을 하고 있다.2, a torsion bar 10 having a circular cross section is provided with a pipe 20 so as to surround an outer circumferential surface thereof. The torsion bar 10 is connected at its one end with a sawtooth or hexagonal shape to simply twist the torsion bar 10 It plays a role.

따라서, 상기 토션 바의 외주연에 설치되는 파이프의 역활은 토션바를 비틀어 주는 역활만 할 뿐 토션 바의 단면적, 길이 등에는 아무런 영향을 미치지 못한다는 문제점이 있다.Therefore, the role of the pipe installed at the outer circumference of the torsion bar serves only to twist the torsion bar, but has no effect on the cross-sectional area, length, etc. of the torsion bar.

본 발명은 상기의 결점을 해소하기 위한 것으로, 로어 암등의 비틀림력을 강성에 의해 원상태로 복귀시키기 위한 토션 바의 외주연에 토션 파이프를 설치하여 상기 토션 바의 길이를 늘이지 않고 높은 비틀림력을 얻을 수 있도록 한 차량용 토션 바를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above drawbacks and it is an object of the present invention to provide a torsion pipe for restoring the torsional force of a lower arm to its original state due to its rigidity by providing a torsion pipe at the outer circumference of the torsion bar, The present invention provides a torsion bar for a vehicle.

본 발명의 실시예를 첨부 도면에 의하여 상세히 설명 하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 도 3 에 나타낸 바와같이, 로어아암등의 비틀림력을 강성에 의해 원상태로 복귀시키기 위한 토션 바(10)에 있어서, 상기 토션 바(10)의 비틀림 반력을 전달받아 이 비틀림력을 증강시키기 위해 외주연에 토션 파이프(30)가 설치된다.As shown in Fig. 3, the present invention relates to a torsion bar 10 for returning a torsion force of a lower arm or the like to an original state due to rigidity, wherein the torsion bar 10 receives the torsion reaction force of the torsion bar 10, The torsion pipe 30 is installed on the outer periphery.

한편, 상기 토션 파이프(30)의 끝단에 연결 파이프(40)가 설치되고 이 연결 파이프(40)의 일단은 앵커 브라켓트(1)에 고정된다.A connecting pipe 40 is provided at the end of the torsion pipe 30 and one end of the connecting pipe 40 is fixed to the anchor bracket 1. [

이때, 상기 토션 파이프(30)와 연결 파이프(40)는 다각형상 또는 이맞물림에 의해 일체로 연결된다.At this time, the torsion pipe 30 and the connection pipe 40 are integrally connected by polygonal or meshing.

따라서, 상기 토션 바(10)가 비틀리게 되면 이 비틀림 반력이 강재 스프링으로 이루어진 토션 파이프(30)에 전달되고 이 토션 파이프(30)가 비틀어짐으로서, 토션 바(10)의 비틀림력과 토션 파이프(30)의 비틀림력이 더하여져 상기 토션 바(10)의 길이를 늘이지 않고서도 높은 비틀림력을 얻을 수가 있다.Therefore, when the torsion bar 10 is twisted, the torsion reaction force is transmitted to the torsion pipe 30 made of a steel spring, and the torsion pipe 30 is twisted so that the twisting force of the torsion bar 10, The torsional force of the torsion bar 30 is added, and a high torsional force can be obtained without increasing the length of the torsion bar 10.

본 발명은 로어아암의 비틀림력을 강성에 의해 원상태로 복귀시키기 위한 토션 바의 외주연에 토션 파이프를 설치하여 한정된 레이아웃에서 높은 비틀림력을 얻을 수 있음으로써, 레이아웃 설계변경이 용이하며 전체적으로 시스템 크기를 작게할 수 있어 중량 및 가격 측면에서 매우 높은 유용한 발명이다.The present invention provides a torsion pipe at the outer circumference of the torsion bar for returning the twist force of the lower arm to the original state by the rigidity, so that a high twisting force can be obtained in a limited layout, so that the layout design can be easily changed. Which is a very useful invention in terms of weight and cost.
