A coil spring is interposed between a vehicle body and a suspension member which is elastically and swingably supported by the vehicle body and supports a wheel. The suspension member and a vehicle part attached to the vehicle body are connected by a fastening member. The orientation of the suspension member with respect to the vehicle body is forcibly changed so as to increase the distance between the vehicle body and the suspension member at a coil spring interposition portion. An excessive change in the orientation of the suspension member is restricted by the fastening member, and a coil spring is inserted between the vehicle body and the suspension member.

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.

A vehicle includes a rear wheel suspension including a twist beam axle. The vehicle also includes upper and lower mounts for a spring and each defining a seat. The lower mount is disposed on the axle and the upper mount is disposed at a distance and parallel to the lower mount on a frame member. A first adapter is disposed within the lower mount seat and a second adapter is disposed within the upper mount seat. Each adapter defines a groove to receive an end of the spring, a support extending from the groove within an inner diameter of the spring and a wall disposed along a segment of the groove being configured to maintain a position of the spring.

A suspension coil spring includes a lower end turn portion, an upper end turn portion, and a helical effective portion formed between the end turn portions. The lower end turn portion includes a first portion which contacts a lower spring seat irrespective of a load, and a second portion which contacts the lower spring seat or is separated from the same according to the load. The wire diameter of the second portion is greater than that of the first portion and an average wire diameter of the effective portion. The upper end turn portion includes a third portion which contacts an upper spring seat, and a fourth portion. The wire diameter of the fourth portion is greater that of the third portion and the average wire diameter of the effective portion.

The twist axle assembly includes a twist beam which is made of a single integral piece and extends along a length between opposite ends. The twist beam has a middle portion which extends in a first direction and a pair of end portions which extend at least partially in a second direction that is generally transverse to the first direction to reduce twisting stresses within the end portions during operation of the twist axle assembly.

The present disclosure relates to a suspension apparatus for a vehicle, the suspension apparatus including an axle carrier to which a wheel is rotatably coupled, a torsion beam axle having a trailing arm coupled to the axle carrier, the torsion beam axle being disposed in a width direction of a vehicle, a spring lower pad coupled to the axle carrier and having a bump stopper, a spring seated on the spring lower pad, and a shock absorber coupled to the axle carrier and disposed to be inclined toward a rear side of the vehicle.

A suspension apparatus includes a carrier connected to a wheel, a torsion beam axle connected to a vehicle body to rotatably support the carrier, and a steering component connected to the carrier to rotate the carrier relative to the torsion beam axle.
