RANCANG BANGUN TEST BENCH SISTEM MEKANISME CVT (CONTINUOUSLY VARIABLE TRANSMISSION) SEPEDA MOTOR TIPE YAMAHA MIO SPORTY

Sistem transmisi otomatis Continuously Variable Transmission (CVT) telah menjadi pilihan yang diminati dalam sepeda motor modern. Penelitian ini bertujuan untuk merancang dan membangun test bench sistem mekanisme CVT sepeda motor dan mengetahui perbandingan kecepatan pada motor penggerak, drive pulley dan clutch housing. Metode yang digunakan adalah metode rancang bangun dengan proses : (1) Studi literatur; (2) Analisis kebutuhan alat dan bahan; (3) Desain awal; (4) Detail desain; (5) Pembuatan test bench; (6) Uji coba; (7) Penarikan kesimpulan. Desain test bench dibuat menggunakan model 2D dan 3D menggunakan software CAD dan Inventor. Hasil perhitungan didapatkan diameter minimum poros 1 sebesar 6,4mm dan poros 2 sebesar 11,4 mm sedangkan diameter poros 1 dan poros 2 yang dibuat sebesar 39mm maka poros yang dinyatakan layak serta torsi pada test bench didapatkan sebesar 0,95 Nm. ***** The Continuously Variable Transmission (CVT) automatic transmission system has become a desirable option in modern motorcycles. This study aims to design and build a motorcycle CVT mechanism system test bench and determine the speed comparison on the drive motor, drive pulley and clutch housing. The method used is the design method with the process of: (1) Literature study; (2) Analysis of the needs of tools and materials; (3) Initial design; (4) Detail design; (5) Making test bench; (6) Test run; (7) Drawing conclusions. The test bench design is made using 2D and 3D models using CAD and Inventor software. The calculation results obtained the minimum diameter of shaft 1 of 6.4mm and shaft 2 of 11.4mm while the diameter of shaft 1 and shaft 2 made is 39mm, the shaft is declared feasible and the torque on the test bench is obtained at 0.95 Nm
