摘要： U-shaped cushions, also known as shanks or spring members, resiliently support a gang of disks on the frame of a disk harrow. The agricultural disk cushion is manufactured from a round section of raw material which is lighter and more resistant to torsion related failure than traditional rectangular section shanks. Two leg portions are each tapered to have flat surfaces on opposite sides for flush fitting with mounting elements, while a central portion connecting them remains circular in cross section. The round cross section in this critical area can withstand severe omni-directional loading, as its resistance is equal in all directions The spring rate the leg portions of the disk cushion can be tailored individually to meet the requirements of the application.

摘要： A leaf spring assembly includes a safety strap extending along the bottom of a plurality of stacked leaf springs that are held in a stacked relationship by a leaf fastener. The strap is attached to each leaf spring in the stack by fasteners at opposite ends of the spring such that adjacent leaf springs are connected on each side of the fastener. In the event that any one of the springs fails between the leaf fastener and one of the ends at which the strap is attached, the broken pieces of the spring remain connected to the other springs in the stack. This prevents pieces from breaking free of the assembly and creating road hazards in the event of spring failure.

摘要： A leaf spring assembly features a stack of leaf springs having mounting couplings attached at opposite ends. The mounting couplings each have first and second mounting elements clamped together about at least a main spring and a safety spring. The safety spring has retaining elements at opposite ends each having an extension portion and a blocking portion. The extension portion extends past the end of the main spring. Here the blocking portion extends generally perpendicularly from the extension portion to block motion of the mounting coupling should failure cause it to be detached from the stack of springs. This ensures that failure does not cause complete separation of the spring stack and mounting couplings.
