The invention relates to the technical field of forklift driving, in particular to a drive axle and a forklift, the drive axle comprises a drive axle body, a drive motor, a differential mechanism, a half shaft, a planetary gear reducer and a service brake, the drive motor is located on the drive axle body, the differential mechanism is located in the drive axle body, and the half shaft is located in the drive axle body. An input shaft of the differential mechanism is in transmission connection with an output shaft of the driving motor, one end of the half shaft is inserted into the differential mechanism and is in transmission connection with an output shaft of the differential mechanism, and the planetary gear reducer is located on the driving axle body and comprises a sun wheel shaft. The sun wheel shaft is in transmission connection with one end of the half shaft, and the service brake is located between the half shaft and the planetary gear reducer and fixed to the sun wheel shaft. According to the design, the service brake is located at the tail end of the half shaft and located between the half shaft and the planetary gear reducer. Even if the half shaft is broken, the wheels can be braked, and the safety of the vehicle can be improved.
