Abstract
A driveline system and driveline operating method are provided herein. In one example, the driveline system includes a hydraulic coupling designed to rotationally couple to a prime mover and an output interface designed to rotationally couple to a downstream driveline component, and a power take-off (PTO) assembly. The PTO assembly includes a first pump gear rotationally coupled to an input gear that is directly coupled to the output interface, where the first pump gear is designed to rotationally couple to a first pump via a first pump shaft interface and a first pump adapter designed to mount to the first pump.
Claims19
A driveline system comprising:
- a hydraulic coupling configured to rotationally couple to a prime mover and including an output interface configured to rotationally couple to a downstream driveline component;
- and
- a power take-off (PTO) assembly comprising:
- a first pump gear rotationally coupled to an input gear that is directly coupled to the output interface, wherein the first pump gear is configured to rotationally couple to a first pump via a first pump shaft interface;
- and
- a first pump adapter including at least one mounting flange configured to mount to the first pump,
- wherein the at least one mounting flange axially overlaps a section of the hydraulic coupling that includes an impeller and/or a turbine.
A method for operation of a driveline system, comprising:
- transferring mechanical power from an output interface of a torque converter to a power take-off (PTO) assembly;
- wherein the PTO assembly comprises:
- an input gear directly coupled to the output interface and rotationally coupled to a first pump gear that is directly coupled to a first pump shaft interface;
- a housing at least partially enclosing the torque converter and the input gear
- wherein the first pump shaft interface is configured to rotationally couple to a first pump;
- and
- a first pump adapter including at least one mounting flange configured to mount to the first pump,
- wherein the at least one mounting flange axially overlaps a section of the housing that includes the torque converter.
A power take-off (PTO) assembly comprising:
- an input gear directly coupled to an output interface of a torque converter;
- an idler gear meshing with the input gear and a first pump gear, wherein the first pump gear is configured to rotationally couple to a first pump via a first pump shaft interface;
- a first pump adapter including at least one mounting flange configured to mount to an enclosure of the first pump;
- and
- a housing at least partially enclosing the input gear and an impeller and a turbine in the torque converter,
- wherein the idler gear is coupled to an idler shaft that is supported by the housing, and wherein the at least one mounting flange axially overlaps a section of the housing.
