Abstract: An axle assembly that may have a housing and a carrier housing. The axle assembly may include one or more quiet lubricant reservoirs that may not receive rotating components of the axle assembly. A seal may be provided in a channel that may be disposed between the housing and the carrier housing.

Abstract: A drive axle system and a method of control. The drive axle system may include a first drive axle assembly and a second drive axle assembly that may be operatively coupled via a slip clutch.

Abstract: A drive axle system and a method of control. Shifting of a drive axle assembly between different speed ranges may be inhibited when the inclination of the vehicle exceeds a threshold value. An inclinometer may be used to detect inclination of the vehicle.

Abstract: A tire inflation system having a sleeve assembly. The sleeve assembly may be disposed proximate a spindle and may receive pressurized gas. A wheel end seal assembly may be disposed between the sleeve assembly and a hub to help route the pressurized gas.

Abstract: A system for processing applications from customers for manufacture of vehicle parts is provided. The system includes a server configured to generate an application interface on a customer client in communication with the server through a network. The server is further configured to receive a completed application for manufacture of a part of a vehicle from the customer through the customer client using the application interface. The completed application has information including a first set of information regarding operating conditions of the vehicle, a second set of information defining specifications for the part of the vehicle for which the application to manufacture is being submitted, and a third set of information regarding another part of the vehicle functionally interrelated with said part of the vehicle for which the application for manufacture is being submitted.

Abstract: A method for converting a non-driven tag axle system to a driven axle system is disclosed where a forward driven axle system is converted to drive an interaxle drive shaft. The interaxle drive shaft is connected to a drive axle head mounted within the tag axle housing. Drive axles are connected to drive axle head. In another embodiment, a forward driven axle system is removed from a first position on the vehicle frame and the tag axle is removed from a second position on the vehicle frame. A differential is installed in the tag axle and it is located in the first position. The forward driven axle system is located in the second position and connected to the differential in the first position.

Abstract: An inter-axle differential assembly comprises an input shaft, an output shaft arranged coaxially with respect to each other, differential gearing and a dedicated reversible lubrication pump disposed between the input and output shafts. The reversible gerotor type lubrication pump includes a rotor driven by the input shaft, and an impeller, both disposed within a pump body coupled to a side gear drivingly connected to the output shaft. Thus, the lubrication pump generates lubricant flow only during the differential action between the input shaft and the output shaft, i.e. only when needed and at a flow rate proportional to the speed difference across the differential assembly. An oil flow generated by the lubrication pump is supplied to various components of the inter-axle differential assembly through a gallery of fluid passages.

Abstract: An improved drum brake assembly is provided that reduces vibration and excessive movement of the cam washer by including at least one lug extending from a cam tube seal and at least one corresponding notch on a cam washer that positions the cam washer on the cam tube. By reducing vibration of the cam washer, wear of the components of the drum brake assembly is reduced. Reduction of vibration also serves to eliminate unpleasant noise during vehicle operation caused by the vibration. Reducing vibration of the cam washer also decreases contact of the cam washer with other metallic components and surfaces within the vehicle, which protects the cam washer from potential corrosion caused by such contact.
