A narrow track tilting vehicle includes an undercarriage centered over a contact point, an upper chassis configured to pivot about a mobile longitudinal axis, and a cradle assembly configured to allow the mobile axis to move laterally relative to the contact point. In wheeled embodiments, the configuration of the carriage allows the upper chassis to tilt in response to centrifugal forces, while allowing the wheels to remain perpendicular to a level surface along which the vehicle is traveling. When the vehicle is traveling along a surface that is canted relative to the level surface, the configuration of the carriage allows to the upper chassis to remain upright relative to the level surface, and the wheels to extend perpendicular to the canted surface.

An automated guided vehicle (AGV) includes a suspension system for movably coupling wheels of the AGV with its frame. The system includes a rocker pivotally attached to the frame. A drive wheel and casters are mounted to the rocker on opposite sides of the rocker pivot axis so that the drive wheel and the pair of casters move together about the pivot axis in the same rotational direction when the rocker tilts. The system can be employed in a simple and elegant manner to ensure continuous traction between the drive wheel and the ground while protecting the drive unit from overload when the AGV traverses uneven terrain.

Embodiments of a suspension for a vehicle is provided. The suspension includes, for example, a frame and a locking assembly. The locking assembly inhibits tipping of a frame of the vehicle when tipping of the frame is detected.

A stabilizer includes: a stabilizer bar made of a pipe material; and a stabilizer link that couples the stabilizer bar and a suspension device. The stabilizer link includes a ball stud which includes a shaft portion inserted to and fixed in an opening end of the stabilizer bar and a ball portion formed at a leading end of the shaft portion, a housing which rotatably supports the ball portion, and a flexible dust cover which includes one end attached on the housing so as to be unmovable in a ball stud axis direction and the other end attached on at least either of the shaft portion and the stabilizer bar and which seals a space between the housing and the ball stud.

A semi-finished product (31) includes a first curved portion on one end of a plate-shaped bridge portion (33), and a second curved portion (37) on the other end of the bridge portion (33). The second curved portion (37) includes at the end a second lock portion (51) to lock with a first lock portion (41). The bridge portion (33) and the inner circumferential surfaces of the first and second curved portions (35, 37) are pressure-contacted and caulked on the outer circumferential surface of the stabilizer bar (11) by first and second dies (61, 62). At least one of the inner circumferential surfaces (31c) of the first and second curved portions (35, 37) and the outer circumferential surface of the stabilizer bar opposed to the inner surfaces (31c) is formed with an anti-slippage portion (38). The inner circumferential surfaces (31c) of the first and second curved portions (35, 37) and the outer circumferential surface of the stabilizer bar (11) have an anti-slippage material (Co) therebetween.

A stabilizer manufacturing apparatus is adapted to bond a rubber bush, which is a bush made of rubber disposed between a stabilizer and a vehicle body, to a rubber bush bonding location where an adhesive layer of the stabilizer is formed. The stabilizer manufacturing apparatus is provided with: a curing furnace for heating the stabilizer, which is conveyed by a manufacturing line conveying unit and has the rubber bush bonding location with which the rubber bush is press-contacted, and performing the bonding; a heat source device that heats air; a blower device that sends the air heated by the heat source device as hot air; and a plurality of nozzles that are disposed along the manufacturing line conveying unit in the curing furnace and blow the hot air against, at a near position from, a location in the vicinity of the rubber bush bonding location of the stabilizer.
