Continuous variable transmission




Many people use motorcycle scooter for daily activities. There for, you must know how the new scooter work! they use CVT system.


Continue Variable Transmission or CVT is the transfer rate system for full automatic speed according to engine speed. This system does not use gear transmission, but the V-belt it self.

CVT works fully automatic transmission, that  affected by the load and engine speed.




During Idle Rotation

The engine speed is not connected to the rear wheel stalled due to the rotation of the centrifugal clutch and the clutch does not touch on the clutch housing. you can read the system using this picture below .


energy from engine passed to the rod that moving the front pulley. the front pulley is closing (narrow), but the rear pulley is open wide. this action give v-belt to rotate the pulley, but the wheel is still stop.

During Intermediate Rotation

After the idle rotation, we can accelerate the scooter. rotation engine forwarded to the rear wheel stalled due to the centrifugal clutch and the clutch does not touch on the clutch housing.


During High Rotation

The higher the engine speed up to further strengthen the centrifugal force on the roller so as to suppress weigth primary sliding sheave is stronger, then the position of the V-belt will be squeezed and expands to a larger diameter.


Conclusion

Transfer rate in engine rotation speed is set automatically by the second pulley connected by a Van-belt no longer need to move the gear speed.

Inilah 6 Standar Gambar (JISC, NNI, DIN, SNI, ANSI, ISO) dan 10 Peralatan Dasar Gambar Teknik

Image
1.     Standar Gambar Teknik Standar gambar teknik merupakan suatu keseragaman yang telah disepakati bersama dengan tujuan untuk menghindari salah pengertian dalam komonikasi teknik. Orang-orang terkait dalam bidang gambar teknik perlu mengetahui tentang standar. Orang-orang terkait tersebut antara lain siswa pada kelompok teknologi dan industri, para perencana produk, operator mesin, operator perakitan, mekanik dan pengontrol mutu dari suatu produk/mesin. Standar gambar teknik dapat diberlakukan di dalam lingkungan perusahaan, antar perusahaan/industri di dalam suatu negara, bahkan standar gmbar teknik dapat diberlakukan pada industri antar negara yang dikenal dengan Standar Internasional atau disingkat SI. Negara-negara yang sudah membuat standar antara lain : a.     Japanese Industrial Standart (JIS)      Lebih lengkapnya : JISC b.     Nederland Normalisatie Instituut (NNI)    ...

Wanna Know Engine Ignition? Read this Function and Development of Ignition System First

Image
A.Ignition system       An engine can generate power due to the combustion occurs in the engine. Powered engine combustion heat is converted into mechanical energy, called engine fuel.      There are some kind of engine fuel, which is the gasoline engine. In the gasoline engine thermal energy obtained by burning a mixture of fuel and air in the cylinder. The combustion process in gasoline engine starts the spark jumps.      Engine gasoline, gas into the cylinder is a mixture of air and fuel, the mixture is then burnt to produce combustion pressure later converted into mechanical power.      The system used is an electric ignition system, which is used to generate sparks electrical voltage as a sprinkler. Because the gasoline engine combustion process initiated by a high voltage sparks produced by spark plugs, several methods necessary to produce the required high voltage current.      The ignit...

Jangan Ngaku Anak SMK kalau belum tau sistem pengapian

A.          Sistem Pengapian Suatu mesin dapat menghasilkan tenaga disebabkan didalam mesin tersebut terjadi pembakaran. Mesin bertenaga panas menghasilkan pembakaran yang dirubah menjadi tenaga mekanik, disebut motor bakar. Motor bakar ada beberapa macam salah satunya adalah motor bensin. Pada motor bensin energi panas diperoleh dari hasil pembakaran campuran bensin dan udara di dalam silinder. Proses pemba k aran pada motor bensin dimulai adanya loncatan bunga api. Pada motor bensin , gas yang masuk ke dalam silinder adalah campuran antara udara dan bensin, campuran ini selanjutnya dibakar untuk menghasilkan tekanan pembakaran yang nantinya dirubah menjadi daya mekanis. Sistem yang digunakan adalah sistem pengapian listrik, dimana untuk menghasilkan percikan api digunakan tegangan listrik sebagai pemercik. Karena pada motor bensin proses pembakaran dimulai oleh loncatan api tegangan tinggi yang dihasilkan oleh busi, beberapa metode dip...
