FIELD: armored equipment. ^ SUBSTANCE: on-board water-jet propellers, type "propeller in a checker", with impellers of different direction of rotation and axes of rotation parallel with the hull in the initial position are installed outside from above on the aft. Above caterpillar drive from the gearbox is accomplished from the gearbox by the cardan shaft through the inlet bevel reduction gear installed on a bracket fastened on the hull. The intermediate bevel gear is coupled to the second bevel gear and through the torsion shaft and the outlet bevel reduction gear - to the impeller. The body of the water-jet propeller consists of two parts coaxial with the drive shaft, coupled through cylindrical springs positioned in a circumference and having the possibility to turn relative to each other through a definite angle about the axis of the torsion shaft against the stop of the outlet water jet of the water-jet propeller. The water-jet propeller is installed for turning in a hinge about the horizontal axis of rotation of the intermediate bevel gear of the inlet reduction gear from the initial position in the truck hull to the working (folding-back) position and vice versa. ^ EFFECT: provided reduced longitudinal trimming of the truck afloat, enhanced reliability of truck operation and speed of its motion. ^ 3 dwg |
