Abstract
An auxiliary motor is disposed on an attachment interface of a loader. The loader also has one or more primary motors providing motive power for the loader. The loader also includes lift arms having an attachment interface on a distal portion of the lift arms. The auxiliary motor is disposed on the attachment interface and an auxiliary motor interface is coupled to the auxiliary motor. The auxiliary motor is configured to transfer torque from the auxiliary motor to a powered attachment mounted to the attachment interface.
Claims17
A loader comprising:
- one or more primary motors providing motive power for the loader;
- a lift arm assembly that is pivotably connected to a frame of the loader, the lift arm assembly including one or more lift arm(s) and an attachment interface that is pivotably connected to the lift arm(s), wherein the attachment interface defines a contact surface upon which a corresponding contact surface of a powered attachment bears while the powered attachment is mounted to the attachment interface;
- an auxiliary motor disposed on the attachment interface;
- and
- an auxiliary motor interface coupled to the auxiliary motor and configured to transfer torque from the auxiliary motor to the powered attachment mounted to the attachment interface,
- wherein the auxiliary motor interface is disposed proximate the contact surface of the attachment interface,
- wherein the auxiliary motor interface defines a plurality of teeth for engaging with corresponding teeth in a driven interface of the powered attachment,
- wherein the auxiliary motor interface has a disengaged position in which the auxiliary motor interface is configured to be disengaged from a driven interface of the powered attachment and the plurality of teeth are set back from the contact surface of the attachment interface,
- wherein the auxiliary motor interface has an engaged position in which the auxiliary motor interface is configured to engage with the driven interface of the power attachment and the plurality of teeth are flush with the contact surface of the attachment interface.

A loader comprising:
- one of wheels or tracks to provide motive ability for the loader;
- an internal combustion engine or one or more electric motors coupled to the wheels or tracks to provide power thereto;
- hydraulicly powered lift arms;
- an attachment interface pivotably connected to a distal portion of the lift arms, wherein the attachment interface defines a contact surface upon which a corresponding contact surface of a powered attachment bears while the powered attachment is mounted to the attachment interface;
- an auxiliary motor disposed on the attachment interface;
- and
- an auxiliary motor drive interface coupled to the auxiliary motor and configured to mate with a driven interface of a powered attachment mounted to the attachment interface, the auxiliary motor drive interface configured to transfer torque from the auxiliary motor to the driven interface of the powered attachment,
- wherein the auxiliary motor drive interface is disposed proximate the contact surface of the attachment interface,
- wherein the auxiliary motor drive interface defines a plurality of teeth for engaging with corresponding teeth in the driven interface of the powered attachment,
- wherein the auxiliary motor drive interface has a disengaged position in which the auxiliary motor drive interface is configured to be disengaged from a driven interface of the powered attachment and the plurality of teeth are set back from the contact surface of the attachment interface,
- wherein the auxiliary motor drive interface has an engaged position in which the auxiliary motor drive interface is configured to engage with the driven interface of the power attachment and the plurality of teeth are flush with the contact surface of the attachment interface.
