    Abstract: An axle assembly includes an upper and lower housing joined to form a chamber for a differential gear assembly. The upper and lower housings are fabricated by a method including the steps of forming the upper housing from a first sheet of material and forming the lower housing from a second sheet of material. The upper housing includes an opening for the differential gear assembly and the lower housing includes a bowl portion disposed opposite the opening. The upper and lower housings are joined by a weld to from the axle housing. The lower housing includes leg portions that form a single unified structure with the bowl portion to improve structural rigidity and simplify assembly.

    Abstract: A distributed propulsion system is provided for a multi-unit articulated road train. The distributed propulsion system includes a tractor having a first propulsion system for propelling the tractor. A trailer is secured to the tractor at an articulated joint, such as a fifth wheel or draw bar connection. The tractor has a second propulsion system for substantially propelling the trailer. A load sensor for detecting a load between the tractor and the trailer, preferably the tensile load, is associated with the articulated joint. The load sensor produces a load signal. An input device produces a request signal for actuating the second propulsion system. An electronic control mechanism is electrically connected to the input device and the load sensor for coordinating the various sensors and inputs. The control mechanism commands the second propulsion system in response to the load signal and the request signal such that the trailer is propelled in a controlled manner relative to the tractor.

    Abstract: An isolator to prevent transmitted vibrations includes a ring which fits within a shaft opening of a housing. A bearing is received within the isolator and a shaft is received within the bearing. The vibrations are decoupled from a vibration transmission path by the different material of the isolator. The isolator is preferably manufactured of a rigid laminate material dissimilar to the housing material. Another embodiment of the present invention integrates the isolator directly into the bearing assembly. By manufacturing the outer member of the bearing assembly of the laminated material, the outer member similarly breaks the transmission path of vibrations without the need of the additional member. Noise is thereby substantially prevented from reaching, and from being amplified by, the housing. This greatly reduces the resulting noise and vibration.

    Abstract: A differential includes first and second case members that are attached to each other to define an inner cavity that receives a differential gear assembly. A first tapered roller bearing is associated with the first case member and a second tapered roller bearing is associated with the second case member. One of the first and second tapered roller bearings is inverted such that a defining taper diverges towards the differential gear assembly. The other of the first and second tapered roller bearings is non-inverted with a defining taper diverging in a direction that faces away from the differential gear assembly.

    Abstract: A refrigerant fluid is placed within a driveline component, and in particular an axle housing. This refrigerant fluid is received within a sealed reservoir such that it is sealed from the typical lubricant in the driveline component. The lubricant heats the refrigerant through a housing such that the refrigerant vaporizes within the driveline component housing, thus cooling the lubricant. The vaporized refrigerant travels to a cooling chamber mounted remotely from the reservoir. The cooled refrigerant is cooled to a liquid state, and then returned to the reservoir. Preferably the cooling chamber is positioned on the vehicle frame vertically above the driveline component.
