Abstract
Tracked vehicles have been in use for many years ago thus, there has been increasing interest in articulated tracked vehicles for various applications such as they can be used as transporters for heavy equipment or as heavy earth-moving machines.
Generally, it has been accepted that the wagon-type articulation of tracked vehicles is the simplest type of articulation. However, previous analysis has shown that this kind of articulation createsa problem to steering in the straightening-up position. This paper deals theoretically withthe possibility of changing the hydraulic piston, which used now in articulated tracked vehicles by a double acting hydraulic piston as another solution.It explains the effect of two forces of the piston on the outside tractive force and inside tractive force for the towing vehicle, when using a conventional wagon-type articulation of tracked vehicles with the introduction of double acting hydraulic piston in the system.It show that the length to the width ratio of the towing tracked vehicle is the main factor that affects much more than the other on the forces of the towing vehicle, where the value of this ratio (less than one) gives a good straighting up.
