Abstract
A power unit includes at least one drive source that outputs rotational power to a drive target other than pumps; a first pump rotationally driven by the rotational power of the drive source; a second pump rotationally driven by the rotational power of the drive source, the second pump being different form the first pump; and a power transmission structure that transmits the rotational power of the drive source to the first and second pumps. The power transmission structure includes transmission components and transmits the rotational power to the first pump through one of the transmission components and to the second pump through another of the transmission components.
Claims19
A power unit comprising:
- first and second drive sources each of which outputs rotational power to a drive target other than pumps;
- a switcher shiftable between a connecting state that enables power transmission between the first drive source and the drive target and a shut-off state that disables the power transmission between the first drive source and the drive target;
- a first pump rotationally driven by the rotational power of the first drive source;
- a second pump rotationally driven by the rotational power of at least one of the first and second drive sources, the second pump being different from the first pump;
- and
- a power transmission structure that transmits the rotational power of the first drive source to the first pump and that transmits the rotational power of at least one of the first and second drive sources to the second pump,
- wherein the power transmission structure includes transmission components and transmits the rotational power to the first pump through one of the transmission components and to the second pump through another of the transmission components, and
- wherein the other of the transmission components, which is associated with the second pump, includes:
- a first one-way clutch that receives the rotational power of the first drive source through a route different from a power transmission route which connects the first drive source to the drive target and on which the switcher is located, and
- a second one-way clutch that receives the rotational power of the second drive source.
A power unit comprising:
- first and second drive sources each of which outputs rotational power to a drive target other than pumps;
- a switcher shiftable between a connecting state that enables power transmission between the first drive source and the drive target and a shut-off state that disables the power transmission between the first drive source and the drive target;
- a first pump rotationally driven by the rotational power of the first drive source;
- a second pump rotationally driven by the rotational power of at least one of the first and second drive sources, the second pump being different from the first pump;
- a power transmission structure that transmits the rotational power of the first drive source to the first pump and that transmits the rotational power of at least one of the first and second drive sources to the second pump;
- and
- a shaft extending in an axial direction,
- wherein the power transmission structure includes first and second rotators that are located on one side with respect to the switcher in the axial direction of the shaft and aligned with each other in the axial direction of the shaft,
- wherein each of the first and second rotators includes gear teeth arranged on an outer circumference of the first or second rotator,
- wherein the second rotator receives the rotational power of the first drive source through a route different from a power transmission route which connects the first drive source to the drive target and on which the switcher is located,
- wherein the rotational power is transmitted to the first pump through the gear teeth of the first rotator, and
- wherein the rotational power is transmitted to the second pump through the gear teeth of the second rotator.
