Abstract
A modular axle assembly includes a differential casing with an input axis and a drive axis oriented at a right angle thereto, first and second casing connectors disposed on opposite sides of the differential casing and aligned on the drive axis, each connector including a shaft coupling. An axle extension selectively connectable to one of the casing connectors to extend along the drive axis toward a distal end is provided, a shaft coupling being provided at the distal end. The input axis location in relation to opposing ends of the modular axle may be selectively alterable by connecting the axle extender to the first casing connector or the second casing connector to best suit a specific vehicle installation.
Claims14
A modular axle for a vehicle comprising:
- a differential casing having an input axis and a drive axis oriented at a right angle thereto;
- first and second casing connectors disposed on opposite sides of the differential casing and aligned on the drive axis, each connector including a shaft coupling;
- an axle extension selectively connectable to one of the casing connectors and to extend along the drive axis toward a distal end, the distal end having a shaft coupling;
- and
- a plurality of attachment interfaces configured to enable selective alteration of attachment of the modular axle to the vehicle;
- wherein the input axis location in relation to opposing ends of the modular axle is selectively alterable by connecting the axle extension to the first casing connector or the second casing connector.
A modular axle for a vehicle comprising:
- a differential casing having an input axis parallel to a primary drivetrain axis of the vehicle, and a drive axis oriented at a right angle thereto;
- a pair of casing connectors disposed on opposite sides of the differential casing and aligned on the drive axis;
- a plurality of attachment interfaces configured to enable selective alteration of attachment of the modular axle to the vehicle;
- and
- an elongate axle extension selectively connectable to one of the casing connectors;
- wherein swapping the axle extension connection between the opposing casing connectors shifts the location of the input axis in relation to primary drivetrain axis.
A method of installing a modular axle assembly into a vehicle drive axle comprising the steps of:
- identifying a primary drivetrain axis of the vehicle;
- identifying an input axis for the drive axle;
- determining an offset of the input axis from the longitudinal vehicle axis;
- providing a modular axle assembly having a casing with an input alignable on the input axis, a pair of casing connectors arranged on a drive axis at a right angle to the input axis, each casing connector having a shaft coupling;
- providing a plurality of attachment interfaces on the modular axle assembly;
- providing an axle extension selectively connectable to one of the casing connectors, the axle extension having a shaft extension rotatably disposed therein with a proximally disposed shaft interface configured to operably couple to either of the casing connector shaft couplings and a distally disposed extension shaft coupling;
- connecting the axle extension to one of the casing connectors, the connected axle extension and casing offsetting the casing input in relation to a midpoint between opposite ends of the modular axle assembly, the casing connector being selected to align the modular axle assembly casing input proximate to the input axis;
- selecting one or more of the plurality of attachment interfaces to connect the modular axle assembly to the vehicle in a desired orientation;
- and
- connecting the modular axle assembly to the vehicle.
