Abstract
The utility model belongs to the field of clutches, and particularly relates to a split type cylindrical overrunning clutch used on an electric vehicle. The clutch is provided with a star wheel and an outer loop, a unidirectional limiting device is arranged between the star wheel and the outer loop, the outer loop is formed by disposing a base ring and an outer ring in a split form, the star wheel is used as an inner ring, the unidirectional limiting device which is arranged between the inner ring and the outer ring is a cylindrical roller bearing, the cylindrical roller bearing is provided with a retainer, cylindrical rollers and reset devices, the retainer is equipped with spaced grooves and spaced ledges, each cylindrical roller is arranged in a wedge seam formed by each spaced groove, the outer ring and the inner ring to contact with the outer ring and the inner ring, each reset device is arranged between each spaced ledge and the roller, the surface of the neck portion of the inner ring is circumferentially equipped with an arc-surfaced groove, and a deep groove ball bearing is arranged on the arc-surfaced groove. The split type cylindrical overrunning clutch has the advantages of large torque, low noise, small radial displacement, low axial jumping and prolonging service life.
Description
Technical field
The utility model belongs to clutch field, especially a kind of split type cylinder free wheel device that is used in the electric motor car.
Background technique
Clutch is divided into embedded clutch, engagement sleeve and automatic clutch, a kind of free wheel device is arranged in the automatic clutch, generally adopt free wheel device in the prior art in the electric motor car, it is mainly by star-wheel, outer shroud, ball, push rod and spring constitute, outer shroud is made a gear usually, sky is enclosed within on the star-wheel, in three breach of star-wheel, a roller respectively is housed, each ball is again by spring, push rod is pushed in the formed wedging method of breach of outer shroud and star-wheel, such free wheel device moment of torsion is limited, structural relaxation, radial displacement is bigger, and in use axial runout is also big, the noise height, its performance and function are limited.
Goal of the invention
The utility model is limited at clutch moment of torque in the above-mentioned technology, structural relaxation, radial displacement is big, axial runout is big shortcoming, and a kind of split type cylinder free wheel device that can solve these shortcomings is provided, and this clutch noise is little, axially, circular runout is little.
The realization the technical solution of the utility model is as follows:
Split type cylinder free wheel device, this clutch has star-wheel and outer shroud, be provided with unidirectional limit stoper between star-wheel and the outer shroud, outer shroud is that seat ring and outer ring split setting form, star-wheel is an inner ring, unidirectional limit stoper is arranged between inner ring and the outer ring, unidirectional limit stoper is a roller bearing, this roller bearing has retainer, cylindrical roller and resetting means, retainer is provided with a groove and a rib, cylindrical roller is arranged on a groove and outer ring, in the wedging method that forms between the inner ring with the outer ring, inner ring contacts, resetting means is arranged between a rib and the roller, the inner ring neck surface circumferentially is provided with the cambered surface groove, and this cambered surface groove is provided with deep groove ball bearing.
Described resetting means is a reseting shrapnel, and this reseting shrapnel one end is fixed on the retainer, and the other end contacts with roller.
Described seat ring is provided with several pins.
Be provided with keyway on described seat ring and the outer ring, seat ring is connected by the post key with the outer ring.
Adopted above-mentioned technology, split type cylinder free wheel device, electric vehicle overrunning clutch, be provided with unidirectional limit stoper between this clutch outer body and the inner ring, unidirectional limit stoper is a roller bearing, and roller is a cylindrical roller, and is provided with deep groove ball bearing between outer ring body and the inner ring, the setting of this deep groove ball bearing has reduced the generation of noise, being provided with for the steel ball of deep groove ball bearing of cambered surface groove is set on the inner ring settles, prevented beating of axial-radial, make that the structure of clutch is more stable, increase working life, useful benefit of the present invention is that moment of torsion is big, and noise is low, and radial displacement is little, axial runout is little, has prolonged working life.
