Abstract: The invention relates to a tracked vehicle (10) comprising tracks (38) which are driven, a drive unit (28, 28) for each driven track (38), containing a drive wheel (52) which engages in said track (38), an electric motor (18, 20), a drive train (30, 32) which is connected before the drive wheel (52), and a shaft (34, 36) which driveably interconnects the electric motor (18, 20) and the drive train (30, 32). The inventive tracked vehicle also comprises a vehicle pan (12) which supports each drive unit (26, 28) on a wall (40, 42). The invention is characterized in that vibration damping means (44) are interconnected between the wall (40, 42) and the drive unit (26, 28) so that the drive unit (26, 28) is vibrationally isolated from the wall (40, 42) of the vehicle pan (12).

Abstract: A rammer for an artillery piece with a barrel that can be elevated. The rammer has a cradle upstream of the barrel. The cradle is aligned with the powder chamber, has an accommodation for the shell, travels subject to a guide along a track that parallels the axis of the barrel, is coupled to a piston-and-cylinder mechanism that accelerates it toward the barrel, and is provided with a brake. The piston-and-cylinder mechanism is controlled by pneumatic controls that accommodate a rapid-opening valve. The valve diverts air back and forth between a source of compressed air and a vent. There is a pressure-reduction component with an electrically controlled proportional pressure-regulation valve between the source of compressed air and the rapid-opening valve. Signals from a fire direction system or position generator are forwarded to the electric controls. The pressure-regulation valve is then activated, reducing the ramming pressure in accordance with a prescribed formula as elevation decreases.
