Abstract: A protection module for protecting objects against threats, especially hollow loads. The protection module is made of a material or contains a material which is configured as a three-dimensional metal grid structure or open-pored metal foam which is 4-40 ppi thick. A solid or liquid material can be introduced into the pores of said material. The protection module can be structured in such a way that a sequence of layers is arranged inside a housing (2?,3?,4?,5?), said layer sequence containing layers (7,9) of material embodied in the form of a three-dimensional metal grid structure or open pored metal foam, and layers (6,8,10) of air.

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).
