The invention relates to a combined type driving axle lifting mechanism which comprises a rear cover base, an air bag lifting supporting plate, an axle housing base, an upper thrust support and auxiliary connecting plate assembly and a lifting air bag, the lifting air bag is connected with the air bag lifting supporting plate, and one end of the air bag lifting supporting plate is arranged on the rear cover base. The other end of the air bag lifting supporting plate is connected with an upper thrust support with an auxiliary connecting plate assembly, the upper thrust support with the auxiliary connecting plate assembly is arranged on an axle housing base, a lifting air bag is arranged on a bracket of a suspension, the suspension is installed on a vehicle frame, the lifting air bag is connected with an air storage tank of the whole vehicle, and the air storage tank inflates the lifting air bag. The lifting air bag expands to push the air bag lifting supporting plate to move upwards. A combined structure is adopted, the air bag supporting plate is lifted upwards, stress is shared by the drive axle rear cover, the axle housing and the axle bag, stress is effectively distributed, single-point stress concentration is avoided, and the service life of drive axle parts is prolonged.
本发明涉及一种组合式驱动车桥提升机构,包括后盖底座、气囊提升支撑板、桥壳底座、上推力支架带辅助连接板总成和提升气囊,提升气囊与气囊提升支撑板连接,气囊提升支撑板一端设置于后盖底座上,气囊提升支撑板另一端与上推力支架带辅助连接板总成连接,上推力支架带辅助连接板总成设置于桥壳底座上,提升气囊设置于悬架的托架上,悬架安装在车架上,提升气囊与整车储气罐连接,储气罐对提升气囊充气,提升气囊膨胀推动气囊提升支撑板上移。本发明采用组合式结构,通过气囊支撑板向上提升,由驱动桥后盖、桥壳桥包处分摊受力,有效分配应力,避免单点应力集中,提升驱动桥零件使用寿命。
