Description

The integral wedge free wheel device
Technical field
The utility model belongs to clutch field, especially a kind of integral type 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 integral wedge 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:
The integral wedge 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 outer ring and seat ring are wholely set and 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, roller and resetting means, retainer is provided with a groove and a rib, and 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, and 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 Returnning spring, and this Returnning spring is arranged in the caulking groove of a rib.
Described roller bearing is the voussoir roller bearing, and roller is the voussoir roller, and this voussoir roller bearing and deep groove ball bearing are set to the shared retainer of one, and retainer one side is provided with upper cover plate, and opposite side is provided with lower cover slip.
Described seat ring is provided with several pins.
Described upper cover plate is provided with fin and the inserting pin that matches with caulking groove.
Adopted above-mentioned technology, electric vehicle overrunning clutch, be provided with unidirectional limit stoper between this clutch outer and the inner ring, unidirectional limit stoper is a roller bearing, roller is the voussoir roller, and be provided with deep groove ball bearing between outer ring 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, and useful benefit of the present invention is that moment of torsion is big, noise is low, radial displacement is little, and axial runout is little, has prolonged working life.
