Abstract

Pengembangan energi alternatif di Indonesia, khususnya pada sektor kendaraan listrik, menjadi salah satu strategi utama untuk mendukung target zero emission dalam upaya penurunan emisi karbon. Dalam hal ini, Urban Electric Vehicle Nogogeni X Evo yang dikembangkan oleh Tim Nogogeni ITS menggunakan sistem transmisi chain and sprocket. Namun, penerapan freewheel clutch pada sistem tersebut menyebabkan terjadinya energy loss saat fase deselerasi, sehingga berdampak pada penurunan efisiensi jarak tempuh gelinding. Penelitian ini bertujuan untuk mengembangkan sistem transmisi alternatif berupa jaw clutch yang mampu meminimalisasi hambatan pada saat deselerasi dan meningkatkan jarak tempuh gelinding kendaraan. Metodologi yang digunakan meliputi observasi lapangan terhadap sistem transmisi terdahulu, studi literatur, perancangan sistem jaw clutch menggunakan perangkat lunak CAD (Solidworks), dilanjutkan dengan proses manufaktur dan pengujian eksperimental. Proses pembuatan komponen utama jaw clutch dilakukan menggunakan mesin CNC Milling dengan material Aluminium 7075, yang dipilih berdasarkan hasil penelitian terdahulu. Desain jaw clutch dengan 10 gigi dirancang dan divalidasi melalui simulasi statis. Evaluasi yang dilakukan untuk sistem transmisi ini, dilakukan proses pengukuran benda kerja setelah dilakukan proses manufaktur, perakitan komponen, dan pengujian jarak gelinding. Proses manufaktur menggunakan mesin CNC Milling Richon dilakukan untuk membentuk geometri cakar dari bahan mentah menjadi benda jadi. Jenis pahat yang digunakan meliputi Flat Endmill, Ballnose Endmill, dan Drill, dengan diameter disesuaikan dengan proses pemotongan pada benda kerja. Parameter pemesinan mencakup cutting speed (Vc) sebesar 90 dan 140 m/min, feeding (fz) sebesar 0,08; 0,12; dan 0,14 mm/teeth, serta axial depth of cut sebesar 3, 5, 8, dan 28 mm. Waktu pemesinan tercatat selama 1 jam 6 menit. Sistem penyalur daya menggunakan tipe rantai & sprocket menggunakan tipe rantai 40 dan rasio sprocket 16 : 28 untuk mencapai kecepatan tertinggi pada proses percobaan. Pengukuran pada benda kerja dilakukan menggunakan jangka sorong dengan toleransi ±0,13 – 0,25 mm dan didapat rata-rata selisihnya ±0,0725mm. Hasil pengujian menunjukkan peningkatan rata-rata jarak gelinding sebesar 134,2 meter, atau 12,27% dibandingkan sistem sebelumnya, menandakan peningkatan jarak gelinding pada sistem transmisi jaw clutch.

The development of alternative energy in Indonesia, particularly in the electric vehicle sector, is one of the key strategies to support the zero-emission target in reducing carbon emissions. In this context, the Urban Electric Vehicle Nogogeni X Evo, developed by the Nogogeni ITS Team, utilizes a chain and sprocket transmission system. However, the application of a freewheel clutch in this system leads to energy losses during deceleration, resulting in reduced coasting distance efficiency. This study aims to develop an alternative transmission system in the form of a jaw clutch, designed to minimize deceleration resistance and improve the vehicle’s coasting distance. The methodology employed includes field observations of the previous transmission system, literature review, design of the jaw clutch system using CAD software (SolidWorks), followed by manufacturing processes and experimental testing. The fabrication of the primary jaw clutch components was conducted using CNC Milling machines and Aluminum 7075 material, selected based on prior research findings. A 10-tooth jaw clutch design was developed and validated through static simulation. The transmission system was evaluated through dimensional measurements of the machined parts, component assembly, and coasting distance testing. The manufacturing process utilized a Richon CNC Milling machine to shape the jaw geometry from raw material into final components. Cutting tools used in the machining process included Flat Endmill, Ballnose Endmill, and Drill, with diameters tailored to the specific features of the workpiece. Machining parameters included cutting speeds (Vc) of 90 and 140 m/min, feed rates (fz) of 0.08, 0.12, and 0.14 mm/tooth, and axial depths of cut of 3, 5, 8, and 28 mm. The total machining time recorded was 1 hour and 6 minutes. Power transmission was achieved using a chain and sprocket system, specifically #40 chain type, with a sprocket ratio of 16:28 to reach maximum speed during testing. Dimensional inspection was conducted using a caliper with tolerance values ranging from ±0.13 mm to ±0.25 mm, resulting in an average dimensional deviation of ±0.0725 mm. The experimental results showed an average coasting distance improvement of 134.2 meters, or 12.27% compared to the previous system, indicating distance deceleration of the jaw clutch system.
