Abstract: A hub-axle assembly (10) and lubrication system thereof includes a spindle (11) having an inner end (12) and outer end (15) with inner (13) and outer (14) bearing assemblies spaced axially on the spindle (11). A hub body (16) is rotatably supported on the bearing assemblies (13, 14) and has a wheel mounting flange (17) extending radially outward therefrom. Lug bolts (18) extend axially outward from the flange (17) with one such lug bolt (18) having an axial bore (24) therein. Grease applied at a grease fitting (23) in the axial bore (24) is transmitted to a lubrication chamber (19) within the hub body (16) via tubing (25) to lubricate the lubrication chamber (19). A circumferential recess (27) in the hub body (16) has at least one aperture (28) therein which is normally closed by an O-ring (29) positioned in the recess (27). However, when the pressure of the grease within the hub body (16) is sufficient to indicate that the lubrication chamber (19) has been lubricated, the O-ring (29) will expand causing grease to flow through the aperture (28).

Abstract: An improved electromagnet assembly is disclosed for use in electrically actuated drum brakes. The electromagnet assembly has a cup shaped stamped metal housing. A center pole is mounted in a central opening in the housing which has stepped edges so as to alternately engage the center pole and form arcuate gaps about the center pole. A flux washer is positioned on the center pole to bridge the gaps for increasing the efficiency of the electromagnet. A solenoid winding is positioned within the opening defined by the housing, the flux washer and the center pole and the opening is closed with a friction material.

Abstract: A leaf spring suspension system for supporting a vehicle is disclosed wherein one end of the spring is longitudinally moveable in load-transferring relationship with the vehicle at varying longitudinal positions along the vehicle frame. Thus, regardless of spring deflection, the axle remains equidistant between the longitudinal positions at which the vehicle's load is transferred to spring, thereby equalizing the load at each end of the spring.
