According to the double-tank closed type air supply system for the air suspension and the control method of the double-tank closed type air supply system, double-tank design is adopted, and in part of working conditions, suspension height adjustment can be achieved without intervention of a compressor C in the air supply system, and compressor operation noise does not exist. In the running process of the vehicle, the low-pressure air storage tank LAT and the high-pressure air storage tank HAT are adjusted, compressed air in the low-pressure air storage tank LAT is pumped into the high-pressure air storage tank HAT through the compressor, the pressure of the air storage tank LAT or the pressure of the air storage tank HAT is recovered to the set state, and in the process, the running noise of the compressor is not perceived by a user. When the height of the suspension is greatly changed, the height of the suspension is quickly adjusted under the action of high differential pressure through intervention of the compressor. During external air supply, the compressor compresses external air and discharges the compressed air into the low-pressure air storage tank LAT, and the compressed air in the low-pressure air storage tank LAT is sucked, compressed and discharged into the high-pressure air storage tank HAT, so that the compression ratio is reduced, the compression efficiency is improved, and the energy consumption and the operation noise of the compressor are reduced.
本发明提供了一种空气悬架用双罐闭式供气系统及其控制方法,采用双罐设计,在部分工况中,悬架高度调节无需供气系统内压缩机C介入,即可实现悬架高度调节,无压缩机运行噪音。在车辆行驶中,对低压储气罐LAT及高压储气罐HAT进行调节,通过压缩机将低压储气罐LAT内的压缩空气抽至高压储气罐HAT中,将储气罐LAT的压力恢复至设定状态或储气罐HAT的压力恢复至设定状态,此过程中压缩机运行噪音用户无感知。在悬架高度变化较大时,通过压缩机介入,在高差压作用下实现悬架高度快速调节。在外界补气时,压缩机将外界空气压缩排至低压储气罐LAT内,将低压储气罐LAT内压缩空气吸入压缩排至高压储气罐HAT内,降低压缩比,提升压缩效率,降低能耗和压缩机运行噪音。
