The invention provides an auxiliary braking device of a drive-by-wire chassis, and relates to the field of auxiliary braking. A housing is included; the device further comprises a pushing assembly, the pushing assembly comprises a ball nut, the ball nut is in threaded connection with a lead screw, and a guiding part for guiding movement of the lead screw is arranged in the shell; the driving mechanism is used for driving the ball nut to rotate; the flow guide mechanism is installed on the ball nut, an oil conveying channel communicated with the flow guide mechanism is arranged in the ball nut, and the oil conveying channel is communicated with a threaded groove of an inner ring of the ball nut; the oil injection mechanism is connected with the screw rod, and the oil injection mechanism is provided with two oil outlets; the two oil outlets are respectively connected with the guide part and the flow guide mechanism. And through the arrangement of the oil injection mechanism and the flow guide mechanism, automatic lubrication can be provided for the ball nut and the guide part, and abrasion caused by long-term operation is reduced.
