Axle negative pressure system, axle assembly and vehicle
Axle negative pressure system, axle assembly and vehicle
The invention discloses an axle negative pressure system, an axle assembly and a vehicle, the axle negative pressure system, the axle assembly and the vehicle comprise a drive axle module and a negative pressure module, the drive axle module comprises a closed drive axle inner cavity and a drive axle shell defining the drive axle inner cavity, and a first through hole is formed in the drive axle shell; the negative pressure module communicates with the drive axle inner cavity through the first through hole, and the negative pressure module can reduce the air pressure in the drive axle inner cavity so that the air pressure in the drive axle inner cavity can be lower than the air pressure outside the drive axle inner cavity. The axle negative pressure system, the axle assembly and the vehicle are good in reliability, and the problem of oil leakage of the drive axle can be effectively solved.
本发明公开了一种车桥负压系统、车桥总成及车辆，该桥负压系统、车桥总成及车辆包括驱动桥模块和负压模块，驱动桥模块包括封闭的驱动桥内腔和限定出驱动桥内腔的驱动桥壳体，驱动桥壳体上设有第一通孔，负压模块通过第一通孔与驱动桥内腔连通，负压模块能够降低驱动桥内腔中的气压以使得驱动桥内腔中的气压低于驱动桥内腔外部的气压。本发明的车桥负压系统、车桥总成及车辆可靠性好，能有效解决驱动桥渗漏油的问题。
