The invention relates to the technical field of vehicle braking, in particular to an auxiliary brake device for a trailer and the trailer. The trailer comprises a tractor and a trailing carriage. The auxiliary brake device for the trailer comprises differential mechanisms, a transmission shaft, an auxiliary brake and a control switch for controlling the work state of the auxiliary brake. The differential mechanisms are connected with axles of the trailing carriage, one end of the transmission shaft is connected with the differential mechanisms, the other end of the transmission shaft is connected with the auxiliary brake, and the auxiliary brake is connected with a frame of the trailing carriage. Braking force generated by the auxiliary brake is transmitted to the differential mechanisms through the transmission shaft and then transmitted to the axles of the trailing carriage from the differential mechanisms, auxiliary braking force is provided for the trailer, the braking performance of the trailer is improved, and the risks of traffic accident occurrence are reduced.
