A spring assembly for a vehicle bogie suspension arrangement. The spring assembly includes a set of washers moulded into an elastomer body. The spring assembly has an axial extension in an axial direction and the washers are arranged relative to each other in the axial direction. At least one of the washers is a spring washer including a spring washer body and at least two spring tongues. Each spring tongue has a spring base connected to the spring washer body and a spring tip distal to the spring base. At least a portion of the spring tongue is located at a non-zero distance from the spring base in the axial direction.

A center pivot suspension system according to various aspects of the present technology may include a multi-piece axle having controls arms that are pivotally connected to a center beam section of the axle. Each control arm may be able to pivot about the center section independently from the opposing control arm. A leaf spring may be coupled to each control arm to help absorb loads applied to a given control arm.

A suspension system for a vehicle includes: a composite leaf spring having a protective member which covers an outer surface of the composite leaf spring; and an abrasion-preventing pad coupled to the composite leaf spring and shielding. The protective member and the abrasion-preventing pad are disposed at a portion of the composite leaf spring to which a U-bolt is mounted.

A spring isolator that may include a reinforcing insert, at least one flow hole, a ramp, a wall, a track/groove, an inner wall, an outer wall, and/or a locator pin. The spring isolator may be molded over the reinforcing insert and/or may be secured to the reinforcing insert via at least one flow hole. The spring isolator may include a ramp, a wall, track/groove, an inner wall, and/or an outer wall that may engage and/or retain a coil spring. One or more locator pins and/or a cavity and raised portion may secure the spring isolator to a spring seat.

A bracket apparatus for a composite spring, may include a lower bracket disposed to come into contact with a composite spring when a U-bolt is fastened to a nut; an upper bracket disposed above the lower bracket so as not to be decoupled therefrom by the nut; and an elastic member disposed between the lower bracket and the upper bracket to provide a force such that the lower and upper brackets move away from each other.
