摘要:
An axle assembly (12) for a vehicle includes a housing (14), a differential assembly (20) rotatably supported within the housing, a differential cover (10) and a gasket assembly (52) positioned between the housing and the differential cover. The gasket assembly includes a body (58) and a magnet (60) coupled to the body. The magnet is positioned in communication with a lubricant located within the interior of the housing.

A differential carrier housing having both reduced weight and improved strength along the operational load path of the housing is provided. The housing includes a hollow rib that extends from a forward end rearward of an outer bearing for an input shaft to a rear end at a flange on the carrier housing that is connected to an axle housing.

Machine tools for cutting metal are provided having a polygon cross-sectional geometry self-centring, high torque transmitting, rotatable tool support bar (21) that is movable along the longitudinal axis of the bar. The tool support bar is coupled to the drive mechanism for rotating the bar, at a point (P) proximate to the exit of the bar from the machine, by a coupling (24) having a slidably mating polygon geometry opening (71) through which the bar passes. In an embodiment of the invention there is further provided means (81-91) for releasably locking the tool support bar (21) in a predetermined extended position.
摘要:
An apparatus (40, 100) with an electric motor (42) including a stator (44, 116, 124) and a rotor (46, 118, 126); a shaft (50, 128) secured to the rotor (46, 118, 126); a gearing assembly (52) coupled with the shaft (50, 128); and a housing assembly (54, 102) defining a non-partitioned interior space (56) housing both the electric motor (42) and gearing assembly (52). The shaft (50, 128) may be unsupported by bearing assemblies and/or free of oil seals and similar sealing engagements between the electric machine and gearing assembly (52). The motor (42) may be an axial flux motor (114) having a single stator (44, 116, 124). The gearing assembly (52) may be a planetary reduction gear assembly (70) with a sun gear (68) mounted on the shaft (50, 128). The apparatus (40, 100) may include only a single electric motor (42) or include a second electric motor (42) and second gearing assembly (52). The embodiments having a single motor (42) may be used to drive a fan (86) or a vehicle wheel (94, 110). The embodiments having two motors (42) may be used as a differential drive.

摘要:
An axle assembly and a method of manufacture. The axle assembly may have an axle housing, a bowl ring, and a bowl cover. The bowl ring may be disposed on a center portion of the axle housing and may extend around a bowl opening. The bowl cover may be disposed on the bowl ring.
摘要:
An outer peripheral surface (11b) of an inner ring (11) extends straight along outer peripheral surfaces of tapered rollers (13), and is open at a front side of a tapered roller bearing (10) which is a lubricating oil (L) supply side. A smaller-diameter end portion of a cage (14) is cut in a radial direction to be open. A hole retaining ring (40) is disposed at a back face side (11c) of the inner ring (11) which is a lubricating oil discharge side, and is fixed at its outer peripheral portion to an inner peripheral portion (12a1) of an extension portion (12a) of an outer ring (12). An inner diameter (D2) of the hole retaining ring is larger than an outer diameter (D1) of a larger rib portion of the inner ring.
摘要:
An axle system (12) includes an axle lubrication level (A1) within an axle housing (16) which is lower than a wheel end lubrication level (W1) within the wheel end assemblies (14A,14B). An opening (48) through the wheel end assembly housing (46A) provides a fluid communication path between the wheel end assembly (14A) and the axle housing (16). A differential assembly rotates adjacent an opening (48) such that lubrication at the wheel end lubrication level (W1) is rotated into the opening (48). The lubricant within the wheel end assemblies (14A,14B) is maintained at the wheel end lubrication level (W1). The shaft (34) enters the wheel end assembly housing (46A) through a shaft opening (49A) which provides a communication path for the lubricant from the wheel end assembly (14A) back into the axle housing (16).
