Introduction

The Continuous Variable Transmission (CVT) system on Vario 125 motorcycle plays a crucial role in channeling engine power to the rear wheels. This system utilizes the V belt that connects the primary pulley (drive pulley) and secondary pulley (driven pulley). The primary pulley movement is directly connected to the crankshaft, while the secondary pulley is driven by the V. Belt. The CVT system is designed to provide smooth and efficient power transmission, but its performance can be affected by various factors, including the angle of the primary pulley.

Background

The Vario 125 motorcycle is a popular model that features a CVT system. The CVT system is designed to provide a wide range of gear ratios, allowing the motorcycle to achieve optimal performance in various driving conditions. However, the performance of the CVT system can be affected by the angle of the primary pulley. The primary pulley angle is a critical parameter that can impact the torque, energy, and acceleration of the motorcycle.

Methodology

This study examines the effect of variations in the primary pulley angle on the performance of Vario 125. The focus is located in an angular variation of 13.5 °, 14 °, and 15 ° (standard). The results show a significant difference in terms of torque, energy, and acceleration.

Variations of Angles and Performance

The results of this study show that the angle of the primary pulley has a significant impact on the performance of Vario 125. The following are the results of the study:

13.5 °: Produces the lowest maximum torque and power, which is 8.32 Nm and 7.27 hp. Torque and energy showed higher fluctuations than other variations.
14 °: Producing the highest maximum torque and power, which is 8.95 Nm and 8.05 hp. This variation also produces the most stable torque and energy.
15 ° (Standard): Producing the second highest maximum torque and power, which is 9.15 Nm and 8.45 hp. This variation shows peak acceleration, reaching 16.16 kph/s in 5.5 seconds.

Differences of Angles, Pulley Ratio Differences

The difference in the angle of the primary pulley has a large impact on the pulley ratio. Variation of 15 ° produces a peak ratio of 2.03, while variations of 14 ° and 13.5 ° produce a peak ratio of 2.23 and 2.36. This different pulley ratio affects the way the engine power is channeled to the rear wheels.

Analyze the Results

The results showed that the angle of the primary pulley's slope had a significant effect on the performance of Vario 125. The angle of 14 ° produced optimal performance with maximum torque and energy, as well as good stability. Meanwhile, the standard 15 ° angle produces a faster peak acceleration.

Implications and Recommendations

This study provides valuable information to understand the workings of CVT and its effect on motorcycle performance. This information can be useful for motorcycle manufacturers to improve vehicle efficiency and performance.

For Vario 125 users, an understanding of the influence of the primary pulley slope angle can help in choosing optimal CVT settings according to the needs and driving preferences.

Conclusion

Variations in primary pulley slope in CVT Vario 125 have a significant impact on torque, energy, and acceleration. Angles 14 ° produce optimal performance, while the standard angle of 15 ° gives a faster peak acceleration. This knowledge can be implemented to improve vehicle efficiency and performance, as well as help users choose optimal CVT settings.
