The invention discloses a wet type drive axle which comprises a motor, an axle housing, a differential mechanism and a hub assembly. The two axle housings are fixed to the two sides of the motor respectively, the two hub assemblies are installed in the two axle housings respectively, the differential mechanism is installed in the axle housings, and the differential mechanism is connected with the motor and transmits power of the motor to the two hub assemblies respectively. Two ends of the motor shaft respectively extend into the two axle housings, one end of the motor shaft is connected with the differential mechanism, and a parking brake assembly is arranged between the other end of the motor shaft and the axle housings; a driving gear shaft, a sun wheel shaft and a planet carrier are rotationally mounted in the axle housing, the differential mechanism is connected with the sun wheel shaft through the driving gear shaft, the sun wheel shaft can drive the planet carrier to rotate, and one end of the planet carrier extends out of the axle housing to serve as a hub; a service braking mechanism is arranged between the sun wheel shaft and the axle housing; the drive axle has the two functions of traveling braking and parking braking, the motor is arranged in the middle, a power source brakes, the inner structure of the drive axle is fuller, and functionality is higher.

    本发明公开了一种湿式驱动桥,包括电机、桥壳、差速器、轮毂组件;两个桥壳分别固定在电机两侧,两个轮毂组件分别安装在两个桥壳内,差速器安装在桥壳内,差速器与电机相连并且将电机的动力分别传递至两个轮毂组件;电机轴的两端分别伸入两个桥壳内,电机轴的一端与差速器相连,电机轴的另一端与桥壳之间设置有驻车制动组件;桥壳内安装有转动安装有主动齿轮轴、太阳轮轴和行星架,其中,差速器通过主动齿轮轴与太阳轮轴相连,太阳轮轴能够驱动行星架转动,行星架的一端从桥壳内伸出作为轮毂使用;太阳轮轴与桥壳之间设置有行车制动机构;该驱动桥具有行车制动和驻车制动两种功能,并且电机中置,动力源制动,驱动桥内结构更加丰满,功能性更强。
