A planet wheel type retarder integrated on a drive axle belongs to the technical field of hydraulic retarders and comprises a retarder part and a drive axle part. The exterior of the retarder part comprises a retarder mounting shell and a rear shell, and the interior of the retarder part comprises a sun gear, a gear ring, a retarder input gear shaft, a thrust bearing, a main speed reduction driving gear shaft, a retarder input driving gear, a planet gear and a driven bevel gear; the drive axle part externally comprises a drive axle right shell, and the drive axle part internally comprises a half axle gear, a differential shell, a half axle bearing, a half axle, a half axle sleeve, a thrust bearing I, an oil seal, a hub bearing, a hub oil seal, an adjusting nut and a differential planetary gear. The retarder and the drive axle are integrated, a planet wheel type mechanical structure is adopted, high-viscosity hydraulic oil or magnetorheological fluid serves as a medium, the size is small, and integration with the drive axle is facilitated.
一种集成于驱动桥的行星轮式缓速器,属于液压缓速器技术领域,包括缓速器部分以及驱动桥部分;所述缓速器部分外部包括缓速器安装壳体以及后壳体,内部包括太阳轮、齿圈、缓速器输入齿轮轴、止推轴承、主减速主动齿轮轴、缓速器输入主动齿轮、行星轮以及从动锥齿轮;所述驱动桥部分外部包括驱动桥右壳体,内部包括半轴齿轮、差速器壳体、半轴轴承、半轴、半轴套管、止推轴承Ⅰ、油封、轮毂轴承、轮毂油封、调整螺母以及差速器行星齿轮。本发明将缓速器与驱动桥集成,采用行星轮式机械结构,介质为高粘度液压油或磁流变液,体积较小,便于与驱动桥集成。
