Abstract
A steering assembly for a hydraulic steering system is disclosed. The steering assembly includes a steering input device and an auxiliary drive assembly. The auxiliary drive assembly includes a lock valve body with one or more fluid passages that facilitates regulation of a fluid flow in response to an input from the steering input device. The lock valve body has a surface and a guide bore. Further, an electric pump is included that has an electric motor with a drive train unit. The electric pump is adapted to be mounted to the surface and the drive train unit is adapted to be positioned through the guide bore and operably coupled to the one or more fluid passages to regulate the fluid flow in the one or more fluid passages.
Claims20
A steering assembly for a hydraulic steering system, comprising:
- a steering input device including a helm pump;
- and
- an auxiliary drive assembly including:
- a lock valve body with one or more fluid passages that facilitate regulation of a fluid flow in response to an input from the steering input device, the lock valve body including a surface and a guide bore;
- and
- an electric pump including an electric motor with a drive train unit, the electric motor adapted to be mounted to the surface and the drive train unit adapted to be positioned through the guide bore and coupled to the one or more fluid passages so that the electric pump selectively regulate the fluid flow in the one or more fluid passages.
An auxiliary drive assembly for a hydraulic steering system, comprising:
- a lock valve body with a recess and a guide bore, the lock valve body including:
- at least two input ports to receive a fluid as input;
- at least two delivery ports to deliver the fluid as output;
- a fluid passage defined between the at least two delivery ports;
- a first spool valve adapted to regulate a fluid flow from the at least two input ports to the at least two delivery ports;
- and
- an electric pump including an electric motor with a drive train unit, the electric motor adapted to be received into the recess and the drive train unit adapted to be positioned through the guide bore and coupled to the fluid passage so that the electric pump selectively regulates the fluid flow in the fluid passage.
A watercraft, comprising:
- a steering assembly including:
- a steering input device;
- and
- a helm pump adapted to be actuated by an input of the steering input device;
- and
- an auxiliary drive assembly including:
- a lock valve body fluidly coupled to the helm pump, the lock valve body including one or more fluid passages that facilitate regulation of a fluid flow in response to the input from the steering input device, the lock valve body including a surface and a guide bore;
- and
- an electric pump including an electric motor with a drive train unit, the electric motor adapted to be mounted to the surface and the drive train unit adapted to be positioned through the guide bore and coupled to the one or more fluid passages so that the electric pump selectively regulate the fluid flow in the one or more fluid passages.
