The invention relates to the technical field of engineering machinery, in particular to an overrunning clutch and engineering machinery. The overrunning clutch includes an intermediate input shaft, an outer ring gear, an inner star wheel, a retainer assembly and an inner ring gear; the outer ring gear is arranged on the intermediate input shaft, and a mounting ring groove is formed in one side of the outer ring gear; the inner star wheel is mounted in the mounting ring groove; the retainer assembly comprises a retainer, a plurality of pin rollers and a plurality of elastic pieces, the retainer is arranged between the inner star wheel and the outer peripheral face of the mounting ring groove, and the multiple pin rollers and the multiple elastic pieces are arranged on the retainer; and the inner ring gear is arranged on the intermediate input shaft and is in floating connection with the inner star wheel, so that the pin rollers are uniformly stressed. According to the overrunning clutch, the inner ring gear is in floating connection with the inner star wheel, so that the inner star wheel and the pin rollers have an automatic alignment function relative to the outer ring gear when the overrunning clutch is from overrunning to lockup, and mutual interference with the axial stress of the inner ring gear is avoided, so that the pin rollers are always kept in a centering state relative to the working surfaces of the outer ring gear and the inner star wheel when the pin rollers are locked, and the pin rollers are uniformly stressed.
Description
technical field [0001] The invention relates to the technical field of construction machinery, in particular to an overrunning clutch and construction machinery. Background technique [0002] Aiming at the special working conditions of the loader, currently the more common loader uses a gearbox, the gearbox adopts a roller type overrunning clutch, and the roller type overrunning clutch usually includes an outer ring gear, an intermediate shaft gear, an inner star wheel, a roller and a The inner star wheel is set in the outer ring gear and supported on the intermediate bearing gear through bearings. Since there is a gap when the bearing is assembled, the outer ring gear will tilt to one side. Because the inner star wheel and the intermediate shaft gear adopt When the clutch is locked, the force on the contact surface of the roller, the inner star wheel and the outer ring gear will be tilted, resulting in unbalanced and uneven force on the roller, so that the intermediate shaf...
