The invention relates to the technical field of vehicles, in particular to a magnetorheological fluid retarding non-drive axle and a vehicle. The non-drive axle comprises a non-drive axle shell and wheel input shafts, the two ends of the non-drive axle shell are internally connected with the wheel input shafts respectively, the non-drive axle further comprises a working cavity, a screw and an oil storage cavity, the working cavity is a closed cavity located in the non-drive axle shell, and an oil inlet and an oil outlet which can be closed are formed in the two ends of the side wall of the working cavity respectively. An electromagnetic device is further arranged outside the side wall of the working cavity; the screw is located in the working cavity, corresponds to the electromagnetic device, is connected to the inner end of the wheel input shaft in series and is meshed with a working cavity stator to form a screw pump structure. A circulating oil way is formed between the oil storage cavity and the working cavity, magnetorheological fluid is adopted, the heat dissipation and lubricating performance is improved, and the torque of the screw can be controlled by controlling the magnetic force of the electromagnetic device.
