Abstract
The invention discloses a clutch device of a gearbox. The clutch device of the gearbox comprises a gearbox output shaft. A first stopper, a second stopper and a sprocket are sequentially disposed on the output shaft. The first stopper is fixed on the output shaft. The second stopper is movably sleeved on the output shaft. One end face of the first stopper is provided with a plurality of first locking grooves. The end face of the second stopper, which is close to the first stopper, is provided with second locking grooves corresponding to the first locking grooves. The first locking grooves are fitted with the second locking grooves to form rectangular-section holding channels which contain steel balls. A return spring is disposed between the second stopper and the sprocket, while gaps are reserved among the second stopper, the sprocket and the return spring. The end face of the second stopper, which is far away from the first stopper, is provided with a plurality of engaging-disengaging male teeth, one end face of the sprocket is provided with engaging-disengaging female teeth meshing with the engaging-disengaging male teeth, and a fastener is disposed at the other end of the sprocket. The clutch device is simple in structure, easy to implement, convenient to assemble and maintain, high in transmission stability and long in service life.
