The integrated air supply unit of the air suspension comprises a damping support and a motor, and the motor and a compression pump body are installed on the damping support; the distribution valve assembly is mounted on one side of the motor; an operation inner cavity, a first cavity and a second cavity are formed in the compression pump body, a first compression cavity and a second compression cavity are formed in the two ends of the operation inner cavity respectively, a first piston and a second piston are arranged in the operation inner cavity, and the first piston and the second piston are driven by a main shaft of a motor to axially move in the same direction; the first compression cavity and the second compression cavity are both communicated with the first cavity, the second cavity is communicated with the second compression cavity, the second cavity is provided with an exhaust port, the exhaust port is connected with an exhaust heat dissipation pipe, the exhaust heat dissipation pipe is connected with the distribution valve assembly through a first connecting pipe, and the secondary air inlet is connected with the distribution valve assembly through a second connecting pipe. A two-stage compression air pump structure is adopted, and the problems that an existing air supply unit is large in size, heavy in mass, large in noise and poor in heat dissipation effect are solved.
本发明公开了一种空气悬架的集成式供气单元,包括减震支架和电机,电机和压缩泵体安装在减震支架上;分配阀总成安装在电机的一侧;压缩泵体的内部设置有运行内腔、第一腔室和第二腔室,运行内腔的两端分别设置有第一压缩腔和第二压缩腔,内部设置有第一活塞和第二活塞,第一活塞和第二活塞由电机的主轴驱动进行同向轴向运动;第一压缩腔和第二压缩腔均与第一腔室相连通,第二腔室与第二压缩腔相连通且第二腔室上设置排气口,排气口上连接有排气散热管,排气散热管通过第一连接管与分配阀总成相连,二级进气口通过第二连接管与分配阀总成相连。本发明采用两级压缩气泵结构,解决现有的空气供给单元体积大、质量重、噪声大、散热效果差的问题。
