본 발명은 회전평형율을 향상시킨 자동차의 크랭크샤프트에 관한 것으로, 크랭크샤프트(3)의 하부를 이루는 관성부(5)에 양쪽으로 개구된 개구홈(5b)이 형성되는 그 중앙부가 대략 뒤집힌 ″T″자 형상의 티(T)단부(5a)가 형성되거나 또는 중앙를 개구시킨 개구홈(5')만을 형성시키는 한편, 이 티(T)단부(5a)를 형성하는 양 쪽 개구홈(5b)또는 중앙을 개구시킨 개구홈(5')으로 한쪽 부위가 힌지핀(6b, 6b')에 의해 힌지결합됨과 더불어 다른 쪽이 스프링(6c, 6c')에 고정된 이동추(6a, 6a')로 구성된 아동관성추(6, 6')가 구비되어져, 크랭크 샤프트(3)의 회전속도에 따라 관성부의 관성력 크기를 적절히 변화시켜 회전평형율의 값을 항상 1에 근접시켜 회전시 보다 안정된 평형을 유지 시킬 수 있도록된 것이다.The present invention relates to a crankshaft of an automobile having improved rotational balance, wherein the center portion of which the opening grooves 5b open to both sides are formed in the inertia portion 5 forming the lower portion of the crankshaft 3 is substantially inverted. Both opening grooves 5b forming the T-shaped end 5a of the T " shape or forming only the opening groove 5 'having the center open, while forming the tee end 5a. Alternatively, a moving weight 6a, 6a 'having one side hinged by hinge pins 6b, 6b' with an opening groove 5 'having its center opened and the other side fixed to springs 6c, 6c'. Child inertia weights (6, 6 ') is composed of, according to the rotational speed of the crankshaft (3) appropriately change the inertia force magnitude of the inertia portion of the value of the rotational equilibrium always close to 1 to maintain a more stable equilibrium during rotation It is to be made.
