Abstract
A power take-off adaptor for use in a two-wheel drive vehicle equipped with automatic transmission for supporting a standard power take-off unit, thereby providing power take-off capabilities.
Claims4
An adapter unit for a two-wheel drive motor vehicle of the type having a source of driving torque and a conventional four-wheel drive transmission including a transmission output shaft, the adapter unit comprising:
- a first housing adapted at a first end to receive the transmission output shaft;
- a drive shaft journally supported within the housing for delivering the driving torque from the source of power to ground engaging wheels;
- an input shaft journally supported within the housing and coupled between the transmission output shaft and the drive shaft;
- a power take-off output gear fixed directly to the input shaft;
- an aperture formed in the first housing adjacent the power take-off gear;
- a power take-off unit contained within a second housing, the second housing being completely independent from the first housing and detachable therefrom, the power take-off unit including a power take-off output shaft journally supported therein, and an input gear fixed to the power take-off output shaft, the input gear being in meshing engagement with the power take-off output gear for delivering driving torque to the power take-off output shaft;
- and
- means for detachably securing the first housing to the second housing;
- whereby the adapter unit converts the conventional four-wheel drive transmission for use in the two-wheel drive vehicle and further equips the vehicle with a power take-off provision.
A power take-off arrangement for a two-wheel drive motor vehicle having a source of driving torque, and a conventional four-wheel drive automatic transmission having a transmission output shaft, the power take-off arrangement comprising:
- an adapter unit having a first housing;
- an input shaft journally supported within the first housing and coupled to the transmission output shaft;
- a drive shaft for delivering the driving torque from the source of power to ground engaging wheels;
- an output shaft journally supported within the first housing and coupled to the drive shaft;
- a collar fixed for rotation with the output shaft and axially slidable thereon between a first position coupled to the input shaft for establishing a torque transmission path between the transmission output shaft and the drive shaft, and a second position for interrupting the torque transmission path;
- a power take-off output gear fixed to the input shaft;
- an aperture formed in the first housing adjacent the power take-off output gear;
- a power take-off unit including a second housing, the second housing being independent from the first housing and detachable therefrom, the power take-off unit further including a power take-off output shaft journally supported therein, and an input gear fixed to the power take-off output shaft, the input gear being in meshing engagement with the power take-off output gear for delivering driving torque to the power take-off output shaft;
- and
- means for detachably securing the first housing to the second housing;
- whereby the adapter unit converts the conventional four-wheel drive transmission for use in the two-wheel drive vehicle and further equips the vehicle with a power take-off provision.
