EVALUATION OF THE BRAKING PERFORMANCE OF VAN TRUCKS WHEN DESCENDING HILLS USING AUXILIARY BRAKES

Abstract

The development of the economy in recent years has led to a rapid increase
in the number of trucks for transporting goods in recent years. Van trucks are quite
popular in Vietnam thanks to their small size and maneuverability, which allows
them to transport goods in cities, and even in mountainous areas with complex
terrain with long slopes. When operating in such conditions, the braking system
may have to operate for a long time and there is a risk of overheating, which can
reduce braking efficiency. This paper presents a study to evaluate the
effectiveness of auxiliary braking systems that are necessary when designing
improvements for van trucks when descending hills. The results of the study show
the clear effectiveness of auxiliary braking systems in different operating
conditions, which provides a basis for the development and improvement of
braking systems in the future.
