摘要： A manufacturing method of a coil spring for an automobile suspension includes forming a material into a coil shape; performing a heat treatment step on the material; performing a warm shot peening step on the material, and performing a hot setting step on the material. By performing the warm shot peening step prior to the hot setting step, a stronger compressive residual stress is imparted in a direction along which a large tensile stress acts during actual use of the coil spring, thereby improving sag resistance and durability of the coil spring. A coil spring is also manufactured according to this method.

摘要： The present invention intends to provide a method for manufacturing a high-strength spring, which is capable of generating a higher level of compressive residual stress than that given by conventional methods. This object is achieved as follows: After the final heating process, such as the tempering (in the case of a heat-treated spring) or removing-strain annealing (in the case of a cold-formed spring), a shot peening process is performed on the spring while the surface temperature of the spring is within the range from 265 to 340° C. (preferably from 300 to 340° C.). Subsequently, the spring is rapidly cooled. Preferably, a prestressing process is performed before the shot peening process, or after the shot peening process and before the rapid cooling process. The rapid cooling process may be either a water-cooling process or an oil-cooling process. A forced-air cooling process may be used if the wire diameter of the spring is small.

摘要： A universal joint for coupling a pair of members with a connecting rigid link rockable about two sets of pivot axes. Each of the two members has a corresponding bolt hole through which extend respective stepped bolts defining two pivotal axes about which the link can pivot and rock. The link has opposite end portions each defining a loop through which extends a corresponding stepped bolt connecting a respective end of the link to a corresponding one of the two members the link couples. Each coupling bolt has a length with a major diameter extending axially through a respective coupled member and the corresponding loop of an end portion of the link to which it is coupled. An individual elastic sleeve is disposed circumferentially of the individual major diameter lengths of the bolts and a washer is disposed on each respective major diameter length between an end of the elastic sleeve and an internally threaded nut threaded on an external thread of a minor diameter length at the end of the individual stepped bolts. The link pivots about the elastic sleeves in opposite circumferential directions when coupled members rock. Provision is made for reducing play in the universal joint and allowing the link to pivot at either end about individual axes normal to the individual pivotal axes defined by the corresponding coupling bolts and elastic sleeves thereon. Each elastic sleeve has an elastic collar around each opposite end thereof disposed between the coupled member at one end and the link and at between the link and washer on an opposite end of the sleeve to define at opposite ends of the link corresponding axes normal to the pivotal axes defined by the respective coupling bolts.
