Abstract

본 발명은 자동차용 트랜스밋션의 소음방지장치에 대한 것으로 발명의 근본적인 목적인 입력축의 베어링 일측에서 원주 및 길이방향에 대한 진동을 막아 주는데 있으며, 더 나가서 베어링을 누르는 힘이 회전수에 대해 가변적으로 작용하여 저속일때 가압력이 발생하고, 고속일때는 가압력이 제거되어 회전에 지장을 주지 않도록 배려 하는데 목적이 있다.The present invention relates to a noise reduction device of a transmission for a vehicle to prevent vibrations in the circumferential and longitudinal directions on one side of a bearing of an input shaft, which is a fundamental object of the invention. At the low speed, the pressing force is generated, and at the high speed, the pressing force is removed so as not to interfere with the rotation.

그리고 이를 위한 특징적인 구성은 케이스와 입력축의 사이에 베어링이 축설되어 엔진의 회전력을 전달받는 통상의 트랜스밋션에 있어서, 상기한 베어링의 일측에 키로써 축설되고, 베어링을 향한 측편에 4방향 이상으로 다수의 경사홈을 가진 원판과, 상기한 원판의 경사홈안에 내장시키되, 후방이 경사면으로 이루어지고, 바깥측의 가압스프링과 중심측의 받침스프링에 탄설된 가압블럭과, 상기한 가압스프링의 장력을 조절하기 위해 외측으로부터 나삽한 작은 나사로 형성하여 고속으로 회전할 때는 가압블럭이 원심력에 의해 외측밀려 베어링을 가압하지 않고, 저속으로 회전할 때는 가압블럭이 경사면을 따라 중심쪽으로 밀려가도록 하는데 있다.And a characteristic configuration for this is that in a normal transmission that the bearing is installed between the case and the input shaft to receive the rotational force of the engine, it is built with a key on one side of the bearing, and more than four directions on the side facing the bearing A disc having a plurality of inclined grooves, a built-in in the inclined groove of the disc, the back of which consists of an inclined surface, a pressure block mounted on the outer spring and the support spring of the center, and the tension of the pressure spring It is formed by a small screw inserted from the outside in order to control the pressure block is rotated to the outside by the centrifugal force to pressurize the bearing, when rotating at low speed, the pressure block is pushed toward the center along the inclined surface when rotating at low speed.
