新能源汽车用弹簧

new energy vehicle spring

New energy springs are mainly used in new energy vehicles (battery packs, electric drive systems, chassis suspensions) and energy storage equipment, with core functions such as buffering and shock absorption, component fixation, and contact pre tightening; It needs to meet the special requirements of new energy scenarios, such as high and low temperature resistance (-40~120 ℃), corrosion resistance (suitable for battery electrolyte environment), and lightweight (mostly using high-strength spring steel or composite materials); Its performance directly affects the safety and stability of new energy equipment, for example, the shock-absorbing spring of the battery pack can reduce the damage to the battery cells caused by bumps, and the contact spring of the electric drive system can ensure stable current transmission.
