Description

자동차 조향장치의 충격흡수용 인터메드샤프트Shock absorbing intermed shaft of automobile steering system

본 발명은 자동차 조향장치의 충격흡수용 인터메드샤프트에 관한 것이다.The present invention relates to an shock absorbing intermed shaft of an automobile steering apparatus.

일반적으로 자동차의 조향장치(Steering System)는 자동차의 진행방향을 임의로 바꾸기위한 장치를 말하며, 스티어링휠과 스티어링샤프트 및 컬럼 등으로 이루어진다.In general, a steering system of a vehicle refers to a device for arbitrarily changing a driving direction of a vehicle, and includes a steering wheel, a steering shaft, and a column.

이때 스티어링샤프트(Steering Shaft)는 스티어링휠(조향휠)의 조작력을 스티어링기어에 전달하는 것으로 상부에는 스티어링휠이 하부에는 스티어링기어가 장치된다.At this time, the steering shaft (Steering Shaft) is to transfer the operating force of the steering wheel (steering wheel) to the steering gear, the steering wheel at the top is equipped with a steering gear at the bottom.

이와같은 스티어링샤프트는 일반적으로 20∼30도 기울여서 장착되며 충돌사고시 운전자의 부상을 최소로 하기위해 충격흡수구조를 의무화하고 있다.Such steering shafts are generally mounted at an angle of 20 to 30 degrees and require a shock absorbing structure to minimize the injury of the driver in the event of a crash.

본 발명은 특히 상기 스티어링샤프트와 스티어링기어 사이에 설치되는 인터메드샤프트에 관한 것이다.The present invention relates in particular to an intermed shaft installed between the steering shaft and the steering gear.

이러한 자동차 조향장치의 인터메드샤프트는 도 4에 도시된 바와같이 일측단이 기어측요크(1)에 결합된 하부샤프트(6)와, 상기 하부샤프트(6)의 타측 소정부위가 내측으로 결합되며, 일단부는 샤프트측요크(2)에 결합된 상부샤프트(3)와, 상기 상부샤프트(3)와 하부샤프트(6)가 결합된 부위에 체결되는 고정핀(7)으로 구성된다.As shown in FIG. 4, the intermed shaft of the vehicle steering apparatus includes a lower shaft 6 having one end coupled to the gear side yoke 1, and a predetermined portion of the other side of the lower shaft 6 coupled inwardly. The one end portion includes an upper shaft 3 coupled to the shaft side yoke 2 and a fixing pin 7 fastened to a portion at which the upper shaft 3 and the lower shaft 6 are coupled.

이와같이 구성된 종래 자동차 조향장치의 인터메드샤프트는 기어측요크(1)에 일단이 결합된 하부샤프트(6)의 타측소정부위를 상부샤프트(3)의 내측에 결합시킨후, 상기 상 하부샤프트(3)(6)가 결합된 부위에 고정핀(7)을 체결하여 상 하부샤프트(3)(6)를 고정시킨다.The intermed shaft of the conventional vehicle steering apparatus configured as described above is coupled to the other side of the lower shaft 6 of the lower shaft 6 having one end coupled to the gear side yoke 1 to the inside of the upper shaft 3, and then the upper lower shaft 3 The upper shaft 6 (3) (6) is fixed by fastening the fixing pin (7) to the combined position (6).

이와같이 고정핀(7)에 의해 고정된 상 하부샤프트(3)(6)는 하부샤프트(6)에 외부충격이 가해지면 하부샤프트(6)가 상부샤프트(3)의 내측으로 밀리게 되는데 이때 상 하부샤프트(3)(6)의 결합부위에 고정된 고정핀(7)이 순차적으로 파손되며 하부샤프트(6)에 가해진 충격을 흡수 및 감소시킨후, 상부샤프트(3)로 밀리게 된다.In this way, the upper shaft (3) (6) fixed by the fixing pin (7) when the external shock is applied to the lower shaft (6) is pushed the lower shaft (6) to the inside of the upper shaft (3) The fixing pins 7 fixed to the coupling portions of the lower shafts 3 and 6 are sequentially broken and absorb and reduce the shocks applied to the lower shafts 6, and then are pushed to the upper shafts 3.

전술한 바와같은 자동차 조향장치의 인터메드샤프트는 상 하부샤프트의 결합부위에 체결되는 고정핀의 체결작업이 불편하여 작업성이 저하되고 상 하부샤프트의 결합부위에 고정핀을 체결하기 위해 구멍 및 홈 등을 형성하여야 하므로 작업공정이 과다해진다. 또한 하부샤프트의 충격을 고정핀이 충분히 흡수 및 감소시키지 못한 상태에서 상부샤프트로 전달시킴에 따라 스티어링샤프트에 전해지는 충격량이 더욱 커지는 문제점이 있다.As described above, the intermed shaft of the steering device of the vehicle is inconvenient for the fastening of the fixing pin fastened to the engaging portion of the upper and lower shafts, thereby degrading workability and the hole and the groove for fastening the fixing pin to the engaging portion of the upper and lower shafts. It is necessary to form a back and the work process is excessive. In addition, as the shock of the lower shaft is transmitted to the upper shaft in a state where the fixing pin is not sufficiently absorbed and reduced, there is a problem in that the amount of impact transmitted to the steering shaft becomes larger.

따라서 본 발명의 목적은 스티어링기어와 스티어링샤프트 사이에 설치된 인터메드샤프트의 하부샤프트와 상부샤프트의 결합부위에 충격흡수 및 감소용 고정핀 등을 별도로 사용하지 않고, 하부샤프트가 결합된 상부 샤프트의 소정부위에 다수의 굴곡부를 형성하여 하부샤프트로 가해진 충격이 굴곡부에 의해 다단계로 흡수 및 감소된 상태에서 상부샤프트로 전달되도록 한 자동차 조향장치의 인터메드샤프트를 제공하는데 있다.Therefore, an object of the present invention is to use a predetermined portion of the upper shaft to which the lower shaft is coupled, without using shock absorbing and reducing fixing pins in the coupling portion of the lower shaft and the upper shaft of the intermed shaft installed between the steering gear and the steering shaft. The present invention provides an intermed shaft of a vehicle steering apparatus in which a plurality of bent portions are formed in a portion so that an impact applied to the lower shaft is transmitted to the upper shaft in a state where the impact is absorbed and reduced in multiple stages by the curved portion.
