The Study on the Damage of the Rear-Axle Shaft in a KIA Truck

Abstract

Nowadays, trucks are widely used in the freight transport. Every accident involving a truck as well as any longer disruption of its traffic flow causes great losses. The considered disturbance in traffic flow occurred for a truck with dual tires on its rear axle resulted from the damage to the power transmission system from the engine to the drive wheels of the track. Investigating the cause of one such damage, in the form of rupture of the rear driveshaft, was the purpose of this article. The parameters of the analyzed truck, its wheels, its engine characteristics, the scheme of its cornering, the model of its rear-axle shaft, and the model of loading the bearing set of its rear dual wheel were included in the paper. Additionally, the probable cause of the truck rear axle shaft breakage was established.
