在汽车制造业中,越来越广泛地应用了由一片或几片纵向变断面叶片组成的少片弹簧。少片弹簧和等断面叶片组成的多片弹簧相比,有如下优点:1.大大减轻了弹簧重量(可减轻约30%)。这是由于采用了更合理的叶片的许用应力。2.可以提高弹簧的使用寿命。由于片数或减少近三分之二,采用更完善的板簧加工方法(新的强化方法,表面防锈蚀层,片间加垫等,)在经济上是合理的。片间垫片消除了片间摩擦,这种片间摩擦会造成摩擦锈蚀,而显著地降低板簧使用寿命。消除片间摩擦后,就能在叶片大部分长度的表面上建立耐久的防锈蚀涂层。由于这些措施,即使弹簧加大了应
In the automobile manufacturing industry, less pieces of springs composed of one or more pieces of longitudinally varying cross-section blades are more and more widely used. Compared with the multi-leaf spring consisting of the smaller cross-section blades, the leaf spring has the following advantages: 1. The weight of the spring is greatly reduced (about 30% can be reduced). This is due to the use of more reasonable allowable stress of the blade. 2. Can improve the service life of the spring. Due to the number of sheets or reduced by nearly two-thirds, the use of more sophisticated leaf spring processing methods (new strengthening methods, surface anti-corrosion layer, pads and other pads) is economically justified. Inter-chip spacer eliminates the friction between the films, this friction between the friction friction will cause, while significantly reducing the service life of the leaf spring. Elimination of inter-sheet friction creates a durable anti-corrosive coating on most surfaces of the blade. Due to these measures, even if the spring should be enlarged
