Analysis of CVT (continuously variable transmission) and the influence of variations on the motorcycle

Abstract

This study aimed to determine the working principle, troubleshooting, and the effect of CVT roller weight variations on Suzuki Nex-FI 2014 motorcycles. This research process was carried out by analyzing the measurement results of each CVT component and comparing the results. The research method used is an experimental method by holding the throttle at 3,250 rpm; after it is stable, the throttle is rotated up to 10,000 rpm. The results of troubleshooting analysis and measurement of drive belt wear and tear are from the standard size of 19.50 mm to 18.00 mm, and the tolerance limit for use is 18.60 mm. As for the roller variation test results, using a lighter weight roller, for example, 8 grams and 9 grams, get maximum results at low and medium rotational speeds, compared to using an 11-gram roller (standard). The downside of this 8-gram and 9-gram roller is that it only gets good acceleration and torque at low rotational speeds. While at a high rotational speed less than the maximum. If we use an 11-gram roller, the acceleration and torque will get less than the maximum results but maximum power.
