摘要： According to one embodiment, a coil spring includes a wire rod with a first end and a second end. The wire rod includes a round section portion including a round first cross section perpendicular to a longitudinal direction of the wire rod, a quadrangle section portion including a quadrangle a second section perpendicular to the longitudinal direction, and a variable section portion formed between the round section portion and the quadrangle section portion of the wire rod. The cross section of the variable section portion varies from circular to quadrangle from the round section portion to the quadrangle section portion. The end turn part of the coil spring includes the quadrangle section portion. The width and thickness of the second cross-section are smaller than the diameter of the first cross-section. The area of the second cross section is smaller than the area of the square inscribed in the circle of diameter of the first cross section.

摘要： A damper assembly includes a damper with a pressure tube and a piston slidably disposed within the pressure tube. A first working chamber is defined on one side of the piston and a second working chamber is defined on an opposite side of the piston such that a volume of the second working chamber decreases during a compression stroke of the piston and the volume of the second working chamber increases during a rebound stroke of the piston. A bellow accumulator assembly is included and in fluid communication with the second working chamber. The bellow accumulator assembly includes a housing, a bellow accumulator disposed within the housing, a pressurized gas chamber defined between the housing and the bellow accumulator and an accumulator chamber defined between the bellow accumulator and the second working chamber.

摘要： A spring element that includes one or more loop portions. Each loop portion provides vibration isolation characteristics for the spring element. One or more fastening portions of the spring element enable the fastening or connecting of the spring element to one or more structures. A ratio of a longitudinal measure of each loop portion to a transverse measure of the spring element is between 7.5 and 500. A pair of loop portions may be integrally joined together at a middle section to form a continuous loop. A pair of fastening portions may be integrally joined to opposing sides of the middle section, respectively. One of the fastening portions may be connected to a first structure and the other one of the fastening portions may be connected to a second structure.
