Half-slip clutch gearbox

The invention is applicable to the technical field of gearboxes and provides a half-slip clutch gearbox. An input shaft, a first middle shaft and a second middle shaft which are in transmission connection with each other are arranged. One end of the first middle shaft is connected with a first shell gear through a half-slip clutch. One end of the input shaft is connected with a second shell gear through a first clutch. The second shell gear is also fixedly connected with an output shaft. One end of the second middle shaft is fixedly connected with a third shell gear through a second clutch. Besides, the first shell gear, the second shell gear and the third shell gear mesh with each other and thus can be in transmission through multiple routes respectively. According to the half-slip clutchgearbox, the problems of a large amount of heat dissipation and poor manipulability brought by use of extra-large specification slip clutch are solved; by adopting mutually-independent transmission routes, the systematic saf
