The gearbox is provided with a power input shaft, a first power output shaft and a second power output shaft are arranged on the two sides of the gearbox, and the first power output shaft and the second power output shaft are in transmission connection with the power input shaft through a first intermediate shaft; the first power output shaft and the second power output shaft are in transmission connection with a third power output shaft and a fourth power output shaft on the two sides of the gearbox through two sets of reversing gear mechanisms respectively, the first intermediate shaft is connected with the first power output shaft and the second power output shaft through a first transmission gear set and a second transmission gear set respectively, and the two ends of the first intermediate shaft are each provided with a brake mechanism. The braking mechanism is used for braking the first transmission gear set and/or the second transmission gear set; the gearbox is further provided with a PTO output shaft, and the power input shaft is provided with a PTO sliding sleeve. The gearbox provided by the invention is compact in internal structure and high in integration degree, has high/low-speed switching, forward/backward switching and five output shafts, has comprehensive functions, and can meet the driving requirements of the haunch type mobile chassis.
