벨트 장력 측정장치Belt tension measuring device
본 발명은 벨트 장력 측정장치에 관한 것으로, 보다 구체적으로는, 자동차 엔진 구동 시스템(System)의 벨트 장력 측정은 차량의 고장뿐만 아니라, 정기적인 점검사항의 하나로 주기적으로 측정이 되어야 하는 정기점검 항목으로, 점검의 작업시간 및 편의성 증진을 통해 사용자의 소유를 위한 비용(Ownership Cost)을 낮춰주어 차량의 구매력 향상, 안전하고 빠른 정기점검을 가능하게 할 수 있도록 하기 위한 벨트 장력 측정장치에 관한 것이다The present invention relates to a belt tension measuring device, more specifically, the belt tension measurement of the vehicle engine drive system (System) as a regular inspection item that should be periodically measured as one of regular check items, as well as vehicle failure. The present invention relates to a belt tension measuring device for improving the purchasing power of a vehicle and enabling safe and fast regular inspection by lowering the cost of ownership for the user through the improvement of working time and convenience of inspection.
자동차의 구동용 벨트류의 장력을 측정함에 있어, 기존의 장비 혹은 공구는 벨트에 측정장비를 거치한 후 규정된 스펙(Spec.: 통상 10kg)으로 벨트에 힘을 가해 변형되는 수치를 장력으로 표시해 주는 방식을 사용한다. In measuring the tension of belts for driving a car, existing equipment or tools put the measuring equipment on the belt and apply the force to the belt according to the specified spec. Use the method.
최근 개발되는 차량은 다양한 옵션의 장착 및 배기가스 개선 장치류의 증가로 인해 차량의 엔진룸에 공간이 거의 없어져, 기존의 벨트 장력 측정장비가 벨트로 접근할 수 없는 경우가 대부분이므로, 벨트에 거치하지 않고 장력을 측정할 수 있는 새로운 측정방식의 필요성이 대두 되고 있다. Recently developed vehicles have almost no space in the engine room due to the installation of various options and the increase of exhaust gas improvement equipment, so that the existing belt tension measuring equipment cannot be accessed by the belt. There is a need for a new measuring method that can measure tension without the need for such a measurement.
이에 따라 종래에 벨트의 장력측정을 위하여 주파수 측정방식을 사용하는 장비들이 출시되었으나 그 가격이 대당 100만 내지 400만원으로 정비소에서 사용하기에는 적합하지 않았다. Accordingly, conventionally, equipment using frequency measuring method for tension measurement of the belt has been released, but the price is 1 million to 4 million won per unit, which is not suitable for use in the workshop.
이에 따라 해당 기술분야에 있어서는 벨트의 고유한 진동수를 측정하는 장비로서 마이크로폰을 이용하여, 벨트에 접촉하지 않고, 벨트의 소리 음파 진동수를 수집하는 장치를 개발함으로써, 좁은 엔진룸 내부에서 벨트에 장비를 거치하지 않고 장력을 측정할 수 있도록 하기 위한 기술개발이 요구되고 있다.Accordingly, in the technical field, a device for measuring the inherent frequency of the belt is developed by using a microphone to collect the sound and sound frequency of the belt without contacting the belt. There is a demand for technology development to measure tension without mounting.
