Description :Continuously Variable Transmission (CVT) semakin banyak digunakan oleh industri otomotif, karena CVT dalammenyalurkan daya dari mesin ke roda kendaraan mempunyai kesinambungan dan tidak ada keterputusan, sehinggaperubahan rasio jadi tak terbatas secara progresif diantara harga rasio minimum - maksimum. Sifat CVT yang progresifini memberikan kemampuan yang lebih untuk pemilihan gear ratio. CVT adalah sistem transmisi tanpa gigi yang prinsipkerjanya dengan memanfaatkan perubahan diameter antara pulley penggerak (driver pulley) dan pulley yang digerakkan(driven pulley). Dengan perubahan diameter tersebut mengakibatkan rasio juga berubah secara kontiyu mengikutiperubahan kedua diameter pulley tersebut. Pada penelitian ini dilakukan simulasi CVT dengan melibatkan beratkendaraan, daya dan kecepatan sehingga diperoleh dimensi CVT dan eksperimen model CVT. Eksperimen dilakukanuntuk mengetahui kinerja CVT dalam hal ini rasio, putaran output pada driven pulley dan perpindahan secara translasi(A-x) dan pelaksanaan pengujian dilakukan dengan menggunakan parameter kecepatan dan beban. Hasil eksperimenpada kondisi tanpa beban atau torsi 0 Nm dengan kecepatan putar pengujian pada driver pulley 700 rpm dan 3000 rpmmenunjukkan hasil sesuai dengan simulasi dan respon pada driven pulley berubah secara kontinyu baik A-x, diameterdan rasio. Dengan cara pengujian yang sama dan diberi beban torsi yang berbeda-beda yaitu 2 Nm dan 12 Nm dihasilkanhasil yang berbeda pula yang berupa slip antara belt dengan pulley. Akibatnya adalah rasio (i) ideal pada simulasi tidaktercapai dan berubah-ubah untuk setiap beban torsi yang berbeda.
Description Alt:Continuously Variable Transmission (CT) more and more used by industry automotive, because CVT in transferringenergy from machine to wheel of vehicle have continuity and uninterrupted, so that change of ratio become unlimitedprogressively among price of minimum ratio - maximum. Nature of progressive CVT gives more ability for election ofgear ratio. CVT is system of transmission without principal tooth its job exploited is change of diameter between pulleyactivator (driver pulley) and moved pulley (driven pulley). With change of the diameter result ratio also change bycontinue follow change of second diameter of the pulley. This research is conducted by simulation of CVT entangledheavy of vehicle, power and speed, so that obtained by dimension of CVT. Experiment done to know performance ofCVT in this case the ratio, rotation of output of driven pulley and movement of translation (A-x) and execution ofexamination conducted by using parameter of speed and load. Result of experiment at condition without load or torsion0 Nm with speed turn around examination at driver pulley 700 rpm and 3000 rpm show result as according to simulationand response at driven pulley change by continuously A-x, diameter and ratio. By same examination and given by loadof torsion which different each other that is 2 Nm, 6 Nm and 12 Nm yielded a different result also which is in the formof slip of between belt and pulley. As a result is ratio (ideal i) simulation is not reached and fluctuate to each every loadof different torsion.
