The invention discloses a multi-function parallel double-head output rear transfer case. The multi-function parallel double-head output rear transfer case comprises a gearbox, a clutch and a transfer case body, wherein the clutch is arranged at the front end of the gearbox and the transfer case body is arranged at the rear end of the gearbox. An input shaft is arranged in the gearbox, and the two ends of the input shaft stretch into the gearbox and the transfer case body correspondingly; a first output shaft, a locating shaft and the input shaft are coaxially and sequentially arranged in the transfer case body, a combined sleeve is connected with the outer surface of the input shaft through an internal spline, and a gear-engaging tooth sleeve is mounted on the combined sleeve in a sleeved mode through an external spline; a first gear is mounted outside one end of the combined sleeve through a needle bearing, a spline groove and a fork groove are correspondingly formed in the inner side and the outer side of the gear-engaging tooth sleeve, the external splines corresponding to the spline groove are arranged on the first output shaft and the first gear, and a gearshift device is connected to the gear-engaging tooth sleeve; and a second output shaft and the input shaft are arranged in parallel, a second gear is arranged on the second output shaft, and the second gear is connected with the first gear in a meshing mode. The multi-function parallel double-head output rear transfer case is simple in structure, capable of changing the output direction, and convenient to dismount and maintain.
