Calculations and testing are conducted using simulation methods to obtain suitable angles and lengths for the knuckle. This simulation method involves a series of analyses to obtain data such as static turning radius diagrams, followed by an analysis using the camber calculation formula. The shape, angle, length, and design of the knuckle are considered with regard to driving safety factors. The findings of this study indicate that for a six-meter turning radius, the outer wheel requires a steering angle of δ_0=10.868°, and the inner wheel requires a steering angle of δ_i=77.397°. After improvements, for a 5.5-meter turning radius, the outer wheel requires a steering angle of δ_0=15.960°, and the inner wheel requires a steering angle of δ_i=71.321°. It can be concluded that this design can optimize the performance of the knuckle steering system.</em></p> Idham Nurhadi, Ramdhani Ramdhani, Ibnu Mubarak ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://aeej.ppj.unp.ac.id/index.php/aeej/article/view/212 Wed, 22 Nov 2023 00:00:00 +0000 Distribusi Panas Pengereman pada Sistem Rem Tromol http://aeej.ppj.unp.ac.id/index.php/aeej/article/view/213 <p><em>This study discusses the distribution of heat in the drum brake system using the experimental method using drums as the braking medium. The test was carried out using the brake test prototype process with the application of press and release. The test data collection technique is using three methods, namely by applying the same amount of press and release of the brake (20 seconds of pressure and 20 seconds of release), the application of press and release of the brake is released more than pressed (30 seconds is released and 10 seconds is pressed), and the application of press and release is more pressed than released (20 seconds pressed and 10 seconds released). The results showed that the highest temperature obtained in the application of brakes for 20 seconds and release for 20 seconds on standard drum brakes reached 61.8 <sup>º </sup>C, while applying the brakes for 10 seconds and releasing them for 30 seconds reached 46.3 º C, and applying the brakes for 20 seconds and releasing them for 10 seconds achieved a temperature increase of 73.5 º C.</em></p> <p>Penelitian ini berdiskusi tentang distribusi panas pada sistem rem tromol dengan metode eksperimen menggunakan tromol sebagai media pengereman.
