摘要：【中文】一种通过硬止挡调整沙漏簧变刚度的方法及沙漏簧，采取内面完全为实体的沙漏型橡胶体，在沙漏橡胶弹簧的上端板、下端板和中间支撑板上下分别设置硬止档，通过上端板、下端板和中间支撑板上下的硬止档与实体橡胶的接触变化调整沙漏簧刚度，改善沙漏簧内的应力状况。在实体的沙漏型橡胶体内面中间，分别位于上端板的下面、下端板的上面和中间支撑板的上下两面分别设置硬止挡，这些硬止挡分别与沙漏型橡胶体整体硫化在一起，通过这些硬止挡在沙漏型橡胶体内的作用，调整沙漏橡胶弹簧的刚度。本发明通过在沙漏型橡胶体内设置硬止挡，可以通过硬止挡有效调整沙漏橡胶弹簧的刚度，实现沙漏橡胶弹簧的变刚度。 【EN】A method for adjusting the variable rigidity of an hourglass spring through hard stops and the hourglass spring are characterized in that an hourglass-shaped rubber body with a solid inner surface is adopted, hard stops are respectively arranged on the upper end plate, the lower end plate and the middle supporting plate of the hourglass rubber spring from top to bottom, the rigidity of the hourglass spring is adjusted through the contact change of the hard stops on the upper end plate, the lower end plate and the middle supporting plate and the solid rubber, and the stress condition in the hourglass spring is improved. Hard backstops are respectively arranged in the middle of the inner surface of the solid hourglass-shaped rubber body and are respectively positioned below the upper end plate, above the lower end plate and on the upper surface and the lower surface of the middle supporting plate, the hard backstops are integrally vulcanized with the hourglass-shaped rubber body, and the rigidity of the hourglass-shaped rubber spring is adjusted through the action of the hard backstops in the hourglass-shaped rubber body. According to the invention, the hard stop is arranged in the hourglass-shaped rubber body, so that the rigidity of the hourglass rubber spring can be effectively adjusted through the hard stop, and the variable rigidity of the hourglass rubber spring is realized.
