摘要:
The disclosure relates to an electronic and hydraulic control system to provide variable speed capability for moving a weapon system carried on an armored vehicle. A weapon system is mounted on a turret assembly for movement in the azimuth and elevation directions. Hydraulic motors and piston-cylinder arrangements actuated by a variable electronic control system are employed to drive the weapon system. Through the desired path the control system permits the weapon system to be driven in two ranges, a normal range which is variable and a high speed range which is constant to provide quick motion to a target when needed.

A hydraulic swivel drive with two adjusting cylinder-piston systems the connecting rods of which are pivotally connected to a pivotally mounted member to be actuated by the hydraulic swivel drive. The cylinder-piston units are mounted on a base member, e.g. a base plate, which base member is provided with a servo-valve controlling the supply of actuating fluid to the cylinder-piston units which are arranged in V-formation and are hooked up with the pivotally mounted member so as to be symmetrically arranged with regard to the pivot axis of the pivotally mounted member. The cylinder-piston units are directly connected to the base member and their connecting rods are pivotable relative to the axis of their pertaining cylinder.
摘要:
An adjustable tripod support for the firing tube of a mortar is provided with a digital type of fluidic control system responsive to sensing means which detect a predetermined amount of the azimuth and elevation components of the recoil displacement imparted to the tube during firing. In response to such detection, the fluidic control system functions elevation and aziumth pistons which automatically restore the firing tube to the previously selected sighting inclination. The compressed air required by the fluidic control system is stored in an accumulator arranged to be automatically replenished by the discharge gases generated in the mortar tube during the firing thereof. As the firing tube is subjected to recoil displacement, the rotation of a chordally slabbed control shaft associated therewith serves to unblock one of a pair of sensing orifices for activating the control system to provide the required restoration movements of the firing tube. The combination of chordal edges and sensing orifices in each sensing means can be adjusted to provide a given deadband zone through which each control shaft must be rotated before the respective restoration movement is imparted to the firing tube.
