Further, said sleeve is provided with spring seat, is arranged with back-up ring on the said gear shaft, and an end of said return spring is against on the said spring seat, and the other end of said return spring is against on the said back-up ring.
Further, said back-up ring is fixed on the said gear shaft through jump ring.
Further, said internal spline and said external splines are helical spline.
Further, being arranged with installation shaft outside the two ends of said sleeve holds.
Further, the end of said gear shaft afterbody is provided with spring bearing, and this spring bearing is provided with supports end cap outward.
Further, be provided with oil-impregnated bearing between said unidirectional cover and the said sleeve.
Further, the opening end of said unidirectional cover is provided with pad, and the outside of this pad is provided with baffle ring.
The working principle of the utility model: during engine start; Driving lever on the starter motor withstands on the afterbody and the handsetting gear axle forward of gear shaft, and the actuation gear on the gear shaft is meshed with the input gear of motor, and return spring is compressed at this moment; Starter motor is connected then; The rotation torque of starter motor is passed to roller, sleeve through the unidirectional external gear that puts, at last to gear shaft, thus smooth ato unit.After starter motor quit work, the driving lever on the starter motor no longer withstood on the afterbody of gear shaft, and gear shaft is return under the effect of return spring, and actuation gear on the gear shaft and the input gear on the motor are separated.
Because sleeve is provided with spring seat, gear shaft is provided with back-up ring, thereby is convenient to the installation of spring, and the fixing of back-up ring is convenient in the setting of jump ring.Because internal spline and external splines are helical spline, when promoting gear shaft, gear shaft is that spiral moves forward; Make the actuation gear rotation on the gear shaft move forward; The input gear of being convenient to actuation gear and motor meshes smoothly, reduces the damage of actuation gear, increases the service life.
Because the two ends that bearing is supported on axle sleeve are installed, make the good rigidly of whole one-way element, long service life.At the gear shaft afterbody spring bearing and supports end cap are set, the driving lever of starter motor directly withstands on the supports end cap, and supports end cap can be rotated relative to gear shaft, and gear shaft does not directly contact with driving lever, reduces the wearing and tearing of gear shaft and driving lever.Since be provided with oil-impregnated bearing between unidirectional cover and the sleeve, easy to use.Because the opening end of unidirectional cover is provided with pad, the outside of this pad is provided with baffle ring, and sealing effect is better.
The beneficial effect of the utility model is: adopt said structure, unidirectional putting is provided with external gear, wears gear shaft in the axle sleeve; Gear shaft is through the return spring return, and is not only simple and compact for structure, easy to use; And can shorten the axial length of one-way element, make the axial length of starter motor shorten, thereby make the volume-diminished of starter motor; Save installing space, save material, reduce cost.
