An axle-to-beam connection for a suspension assembly of an axle/suspension system of a heavy-duty vehicle including an axle, a beam, and a top pad. The beam includes an alignment assembly for aligning the axle with the beam. The top pad includes an integrally-formed bump stop boss and is fixedly attached to the axle and removably attached to the alignment assembly of the beam.

A method of making an assembly having a cast iron subassembly. The method may include providing a steel insert having a first joining surface and bonding the steel insert to a cast iron part to form a cast iron subassembly such that the first joining surface may be an exterior surface of the cast iron subassembly.

An axle unit, includes a control arm and a clamping unit that surround a tube region, wherein a first side of the control arm faces away from the tube region, and a second side of the control arm forms a boundary face on the control-arm side of the tube region, wherein the clamping unit can be brought into supporting abutment with the first side of the control arm and has a boundary face on the clamp side, which face defines the tube region, wherein the clamping unit has a first and second clamping parts each having a wedge portion, wherein the wedge portions are formed in such a way that a displacement of the clamping parts substantially in parallel with a clamping axis toward one another results in a narrowing of the tube region transversely to the clamping axis.

A vehicle includes a first steered axle and a second steered axle behind the first steered axle. The second steered axle is steerable independently from the first steered axle. The vehicle includes wheels on the second steered axle. An electric steering motor is connected to the at least one of the wheels.

A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) having a base portion (46) extending along an axis (A) between first and second twist beam ends (42, 44). The twist beam (24) includes a pair of side walls (48) extending downwardly from the base portion (46) and each disposed in spaced relationship with the trailing arms (22). At least one mounting bracket (54) extends from a first mounting bracket end (56) disposed in abutting relationship with a respective trailing arm (22) to a second mounting bracket end (58) disposed in overlaying relationship the side walls (48) of the twist beam (24) for allowing the mounting bracket to axially slip or slide along the side walls (48) of the twist beam (24) and provide for lateral or axial adjustment of the twist axle assembly (20) during the manufacturing process.

The invention is directed to a portal axle for low-slung vehicles, comprising a portal housing 1, 1 into the interior 2 of which is guided proceeding from an axle bracket side a drive shaft 17 on which a drive wheel 3 is arranged so as to be fixed with respect to rotation relative to it, with intermediate wheels 4 which are rotatably mounted on bearing pins 12 in the portal housing 1, 1 and which can be rotatably driven by the drive wheel 3 and by means of which an output wheel 5 which is arranged in the portal housing 1, 1 on an output shaft so as to be fixed with respect to rotation relative to it can be rotatably driven, this output wheel 5 projecting into a hub carrier 6 which can be fixedly connected to the portal housing 1, 1. The drive shaft 17 and the output shaft extend so as to be axially offset, and a brake caliper of a disk brake is arranged radially adjacent to the portal housing 1, 1. The portal housing 1, 1 has on its axle bracket side a mounting orifice 9 which can be closed by a closure part and through which the drive wheel 3 and the intermediate wheels 4 can be inserted into the portal housing 1, 1, wherein the intermediate wheels 4 have a larger diameter than the output wheel 5.

An axle housing assembly includes an axle housing that includes a center portion and a first arm portion that extends from the center portion. The axle housing assembly further includes a wheel end housing that includes a wheel end body that extends from the first arm portion and a spindle that extends from the wheel end body.

An axle and wheel end assembly includes a tubular axle housing with an annular end surface. The axle and wheel end assembly also includes a spindle with an annular end surface welded to the annular end surface of the tubular axle housing at an attachment periphery. The axle and wheel end assembly further includes reinforcing structure fixed to the tubular axle housing and spindle. The reinforcing structure is located to encompass at least a portion of the attachment periphery.

A quint configuration fire apparatus includes a chassis, a body assembly coupled to the chassis and having a storage area configured to receive a ground ladder and a fire hose, a pump coupled to the chassis, a water tank coupled to the chassis, a ladder assembly having a proximal end that is coupled to the chassis, a single front axle coupled to a front end of the chassis, and a single rear axle coupled to a rear end of the chassis. The center of gravity of at least one of the chassis, the body assembly, the pump, and the water tank are positioned to counterbalance a moment generated by a tip load with the ladder assembly extended to the horizontal reach of at least 90 feet.
