The invention discloses a middle-axle new energy trailer automobile drive axle, and relates to the technical field of drive axles, the middle-axle new energy trailer automobile drive axle comprises an axle housing, half-axle housings are mounted on two sides of the axle housing, half-axle sleeves are mounted at one ends of the half-axle housings, and half-axle rods are arranged in the half-axle housings. According to the central-shaft new energy trailer automobile drive axle, a connecting sleeve and a half-shaft rod can be bent along with bumping during transmission by arranging a connecting mechanism, a transmission shaft can slide left and right in the connecting sleeve in order to adapt to the length, and at the moment, the transmission shaft is buffered and energy-absorbed under the cooperation of a damper and a spring; according to the design, the axle housing part of the drive axle, the transmission shaft and the wheel part of the wheel mechanism are kept in a transmission state and are in flexible connection during bumping, so that when the trailer is vibrated, the vibration between the transmission shaft and the axle housing does not interact, the damage to the drive axle is reduced, and the service life is prolonged.

    本发明公开了一种中置轴新能源挂车汽车驱动桥,涉及驱动桥技术领域,包括桥壳,所述桥壳的两侧均安装有半轴壳,所述半轴壳的一端安装有半轴套,所述半轴壳的内部设置有半轴杆。该一种中置轴新能源挂车汽车驱动桥,通过设置连接机构使得连接套和半轴杆传动时会跟随颠簸发生弯折,而传动轴为了适应长度会在连接套内部进行左右滑动,此时在阻尼器和弹簧的配合下起到对传动轴进行缓冲吸能的作用,该设计使得驱动桥的桥壳部分与传动轴和车轮机构车轮部分在颠簸时既保持传动状态的同时也处于柔性连接,因此使得挂车受到震动时,传动轴与桥壳之间的震动不会相互作用,降低了对驱动桥的损伤,提高了使用寿命。
