A suspension assembly for a vehicle may include a wheel support structure operably coupling a wheel to the suspension assembly, a bolt-in spring seat bracket operably coupled to the wheel support structure, and a spring supported by the bolt-in spring seat bracket and disposed between a chassis of the vehicle and the bolt-in spring bracket. The bolt-in spring seat bracket may be adjustable to change a ride height of the vehicle.

A suspension system has a spring which may be prevented from being completely withdrawn and separated from a spring pad even in a situation in which an additional rebound further occurs in a full-rebound state and the spring deviates from a range (a free height of the spring) in which the spring can be extended.

The simultaneous maneuvering system includes a base, a plurality of wheel assemblies including at least one wheel rotatably mounted to the base, a plurality of steering rotors rotatably mounted to the base and the wheel assemblies, and a drive assembly having a drive frame coupled to each of the rotors. Operation of the drive assembly causes simultaneous rotation of the rotors and, thereby, positions the wheel of each corresponding wheel assembly in a desired direction.

A modular hydraulically-adjustable preload and/or cross-over system is disclosed. The system includes a housing configured to couple with a main damper cylinder, the housing including a slave cylinder within a portion of a slave cylinder chamber, the slave cylinder telescopically movable with respect to the housing; a fluid chamber; and a fluid port configured to provide a fluid flow for the fluid chamber, wherein an increase in a fluid volume within the fluid chamber causes a portion of the slave cylinder to telescopically extend from the slave cylinder chamber. A preload flange coupled with the slave cylinder at an end of the housing such that a change in a location of the slave cylinder causes a change in a location of the preload flange.

A method of manufacturing a hollow coil spring which is made of a hollow wire in which a terminal sealed portion is formed on an end portion of the wire. The terminal sealed portion has a rotationally symmetric shape in which an axis passing through the center of the wire is the symmetric axis. The hollow coil spring includes an end wall portion, and an end face arc-shaped curved surface. The end wall portion includes an end face perpendicular to the axis. A distal-end-center closure portion is formed on the axis at the center of the end wall portion. A spring seat includes a base member and a sheet member. An end turn portion of the hollow coil spring is in contact with the sheet member. The end face of the end turn portion is opposed to a stopper wall of the spring seat.

A suspension element of a vehicle includes a coil spring, and a bearing part provided with a main stop. The spring is mounted on the bearing part in such a manner that a first end of the spring comes to bear against the main stop. The bearing part includes a secondary stop placed in front of the main stop, against which secondary stop the first end of the spring bears during a method for assembling the suspension element. The secondary stop is capable of moving away under the effect of pressure exerted by the spring on the secondary stop during a stage of compressing the spring after the spring has pivoted about the spring's rotational axis during a stage involving straightening the spring, so that a second end of the spring is made to interact with a centering element, in order to come to bear against the main stop.
