Abstract
A hydraulic control and driving apparatus for a self-propelled artillery piece includes hydrostatic transmissions for the driving wheels which are driven by hydraulic motors and variable displacement hydraulic pumps. The apparatus includes means for training, elevating and firing the artillery piece by diverting hydraulic fluid from one main pump to the appropriate control elements.
Claims7
Apparatus for producing a flow of pressurized oil for selective operation of the weapon on a self-propelled artillery piece of the type having a plurality of driven wheels and at least one hydrostatic transmission for driving said wheels during self-propulsion, said at least one hydrostatic transmission comprising a variable displacement hydraulic pump and a hydraulic motor driven by flow from said pump, comprising:
- means for selectively diverting the output flow of the variable displacement pump included in said at least one hydrostatic transmission from its associated hydraulic motor, to provide a flow of pressurized oil for operating said weapon;
- and
- means responsive to said flow of pressurized oil for controlling loading, aiming, firing and related functions of said weapon.
