The invention discloses a spiral spring for an extra-heavy vehicle suspension and a preparation method thereof. The spiral spring comprises an equal-wire-diameter main section and a variable-wire-diameter auxiliary section which are integrally manufactured. The equal-wire-diameter main section is arranged on the upper side of the variable-wire-diameter auxiliary section. The wire diameter of the wire-diameter-variable auxiliary section is gradually increased from bottom to top to be equal to the wire diameter of the wire-diameter-equal main section. The suspension has the advantages of being simple in structure, low in cost, large in load, large in stroke, free of maintenance and high in reliability; the compression and extension stroke is increased while the bearing capacity is guaranteed, and the use requirements of an extra-heavy vehicle suspension for large loads, large strokes and small arrangement space can be met. The preparation method has advantages of simple process and easiness in implementation.

    本发明公开了一种用于超重型车辆悬架的螺旋弹簧及其制备方法,螺旋弹簧包括一体制作的等丝径主段和变丝径副段,等丝径主段处于变丝径副段的上侧,变丝径副段的丝径由下至上逐渐增大至等于等丝径主段的丝径,其具有结构简单、成本低、载荷大、行程大、免维护、可靠性高的优点,在保证承载能力的基础上增大了压缩伸张行程,可满足超重型车辆悬架对大载荷、大行程和小布置空间的使用要求;制备方法具有工艺简单、实现容易的优点。
