Abstract

엔진의 회전수를 감지함과 아울러 이를 출력 토오크로 환산하여 변속시의 클러치(RC,FC) 및 브레이크(KB,RLB) 제어 유압을 제어하고 변속 충격을 감소시킴은 제어 시간이 매우 짧을 뿐만 아니란 출력 토오크 환산 계산상 오차에 의해 정밀한 유압 제어가 불가능하여 변속 충격의 저감 효과가 미미하게 됨을 개선하기 위하여, 출력 토오크를 헬리컬 기어를 통해 디퍼런셜 어셈블리(DA)에 전달하는 트랜스퍼 어셈블리의 회전축 일측에 헬리컬 기어에서 발생되는 스러스트에 의해 출력 토오크를 감지하여 이를 보상할 수 있도록 밸브 바디의 밸브 유압을 조절하게 되는 토오크 감지 수단을 설치하여 구성함으로써 변속 충격을 완화시킬 수 있게 된다.It detects the engine speed and converts it to output torque to control the clutch (RC, FC) and brake (KB, RLB) control oil pressure during shifting and reduces shift shock. In order to improve the effect of reducing the transmission shock due to the error in torque conversion calculation, it is impossible to precisely control the hydraulic pressure. By installing the torque sensing means for adjusting the valve hydraulic pressure of the valve body to detect the output torque by the generated thrust to compensate for this, it is possible to mitigate the shift shock.
