Pengaruh Berat Clutch Housing dan Konstanta Pegas Sentrifugal Terhadap Akselerasi Motor Matic 155 CC

Abstract

This study evaluates the impact of varying clutch housing weights and centrifugal spring constants on the acceleration of automatic motorcycles with Continuously Variable Transmission (CVT). The research employed an experimental method using a Dynotest acceleration testing tool. Tests were conducted with three clutch housing weights (816 grams, 800 grams, 771 grams) and three spring constants (39.2 N/mm, 29.4 N/mm, 21.38 N/mm). Results indicated that the combination of a 771-gram clutch housing and a 21.38 N/mm spring produced the highest acceleration, reaching 13.16 m/s² at speeds of 0-5 m/s. Conversely, the combination of an 800-gram clutch housing and a 29.4 N/mm spring showed the lowest acceleration at 11.36 m/s². The appropriate combination of clutch housing weight and spring constant is crucial for achieving optimal acceleration, as the balance of centrifugal force and inertia moment affects the efficiency of power transfer from the engine to the wheels. This study recommends adjusting the spring constant when changing the clutch housing weight to achieve maximum acceleration.
