أنا عندى تفسير بسيط لعملية الإحساس بنقلتين عند التانى...و هو التورك كونفرتر الموجود فى العربية....اللى بيقوم بمقام الدبرياج فى العربيات المانيوال علشان كده بنحس بالفصله دى و كأنك بالظبط دوست على الدبرياج و سبت....
فائدته هى التحكم فى الغيارات و مقارنة طاقة الدخول مع الخروج و تظبيط معدل إستهلاك الوقود تبعا لنتيجة المقارنة و زيادة عزم السيارة .
بيشتغل على ثلاث مراحل:
- مرحلة أولى (السكون) مع بداية تحرك السيارة
-مرحلة تانية (التسارع) مع التحرك حتى الغيار الثانى
مرحلة ثالثة (التعشيق) و هو الإحساس اللى بنحسه بعد النقله التانية.
A torque converter is a modified form of fluid coupling that is used to transfer rotating power from a prime mover, such as an internal combustion engine or electric motor, to a rotating driven load. Like a basic fluid coupling, the torque converter normally takes the place of a mechanical clutch, allowing the load to be separated from the power source. As a more advanced form of fluid coupling, however, a torque converter is able to multiply torque when there is a substantial difference between input and output rotational speed, thus providing the equivalent of a reduction gear
A torque converter has three stages of operation:
- Stall. The prime mover is applying power to the pump but the turbine cannot rotate. For example, in an automobile, this stage of operation would occur when the driver has placed the transmission in gear but is preventing the vehicle from moving by continuing to apply the brakes. At stall, the torque converter can produce maximum torque multiplication if sufficient input power is applied (the resulting multiplication is called the stall ratio). The stall phase actually lasts for a brief period when the load (e.g., vehicle) initially starts to move, as there will be a very large difference between pump and turbine speed.
- Acceleration. The load is accelerating but there still is a relatively large difference between pump and turbine speed. Under this condition, the converter will produce torque multiplication that is less than what could be achieved under stall conditions. The amount of multiplication will depend upon the actual difference between pump and turbine speed, as well as various other design factors.
- Coupling. The turbine has reached approximately 90 percent of the speed of the pump. Torque multiplication has essentially ceased and the torque converter is behaving in a manner similar to a plain fluid coupling. In modern automotive applications, it is usually at this stage of operation where the lock-up clutch is applied, a procedure that tends to improve fuel efficiency.
