Description
Technical field
The utility model relates to a kind of auto parts and components, specifically is a kind of one-way element that is used for automobile starter.
Background technique
Thereby being the electric energy with storage battery, automobile starter is converted into mechanical energy to drive the machine that the engine flywheel rotation realizes engine start.And one-way element is the transmission device that on the starter motor moment of torsion of motor generation is passed to flywheel.
As shown in Figure 1, a kind of one-way element that prior art is used for automobile starter comprises gear 101, star wheel output shaft 102, roller 103 and star wheel 104, described gear 101 is fixed on an end of star wheel output shaft 102, both generally make an integral body, the other end of described star wheel output shaft 102 is in a plurality of rollers 103 are installed in the center hole of an end of star wheel 104, and the other end of described star wheel 104 is the spline housing 105 that inwall is provided with (tiltedly) spline.
During ato unit, the star wheel of one-way element output shaft of motor in starter motor is that splined shaft advances, and makes that (tiltedly) spline on the splined shaft is meshed with the spline housing of star wheel, and simultaneously, the gear of one-way element is meshed with the flywheel of motor.At this moment, the moment of torsion of motor generation passes to motor by one-way element.And behind engine start, the star wheel reversing motion, progressively away from splined shaft, the spline housing of star wheel and splined shaft upper spline break away from.
There is following defective in a kind of one-way element that is used for automobile starter of above structure: when engine start, because the drive-in step inaccuracy of star wheel, the distance that star wheel advances tends to the length above the spline segment of splined shaft, cause splined shaft upper spline section can to contact with the spline in the spline housing with common section end face that combines, make that very likely the spline of step between the external diameter of the internal diameter of splined shaft upper spline section and common section and spline housing is stuck, in case and splined shaft and spline housing are stuck, will make star wheel to break away from splined shaft, will break down, influence the stability of starter motor operation.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of and can avoid star wheel and splined shaft is stuck, reduce the starter motor rate of fault, strengthen a kind of one-way element that is used for automobile starter of starter motor operation stability.
Technical solution of the present utility model is, a kind of a kind of one-way element that is used for automobile starter with following structure is provided, it comprises gear, the star wheel output shaft, roller and star wheel, described gear is fixed on an end of star wheel output shaft, the other end of described star wheel output shaft is in a plurality of rollers are installed in the center hole of an end of star wheel, the other end of described star wheel is the spline housing that inwall is provided with spline, described spline housing is provided with limit stoper near the inner peripheral surface of a side of gear, and the end face of described limit stoper and spline housing are away from the distance of the end face of the gear one end length less than starter motor splined shaft upper spline section.
After adopting above structure, a kind of one-way element that the utility model is used for automobile starter compared with prior art has the following advantages:
Because described spline housing is provided with limit stoper near the inner peripheral surface of a side of gear, the end face of described limit stoper and spline housing are away from the distance of the end face of the gear one end length less than starter motor splined shaft upper spline section, so during engine start, the splined shaft of star wheel motor in starter motor advances, after the top end of limit stoper in the spline housing and splined shaft contacts, star wheel just can't continue to push ahead, and the end face of limit stoper and spline housing are away from the distance of the end face of the gear one end length less than splined shaft upper spline section, so just avoided splined shaft upper spline section to contact with spline in common section end face that combines and the spline housing, and then stopped the step between the external diameter of the internal diameter of splined shaft upper spline section and common section and the stuck phenomenon of spline of spline housing, so reduced the starter motor rate of fault, strengthened the starter motor operation stability.
Description of drawings
Fig. 1 is the half section structural representation (narrating in conjunction with being labeled in background technique, so repeat no more in the following embodiment) of prior art a kind of one-way element of being used for automobile starter.
Fig. 2 be the utility model a kind of one-way element of being used for automobile starter partly look the sectional structure schematic representation.
Shown in the figure
Prior art is used for the component of a kind of one-way element of automobile starter: 101, gear, 102, the star wheel output shaft, 103, roller, 104, star wheel, 105, spline housing;
The utility model is used for the component of a kind of one-way element of automobile starter: 1, gear, 2, the star wheel output shaft, 3, roller, 4, star wheel, 5, spline housing, 6, step surface, 7, center hole.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the utility model is used for a kind of one-way element of automobile starter, and it comprises gear 1, star wheel output shaft 2, roller 3 and star wheel 4.Described gear 1 is fixed on an end of star wheel output shaft 2, and described gear 1 and star wheel output shaft 2 are one.The other end of described star wheel output shaft 2 is in a plurality of rollers 3 are installed in the center hole of an end of star wheel 4, and the other end of described star wheel 4 is the spline housing 5 that inwall is provided with (tiltedly) spline.Described spline housing 5 is provided with limit stoper near the inner peripheral surface of a side of gear 1, and described limit stoper is meant along the step surface 6 of the circumferential ring-shaped step that distributes of spline housing 5 inner peripheral surfaces.The step surface 6 of described ring-shaped step and spline housing 5 are away from the distance of the end face of the gear 1 one ends length less than starter motor splined shaft (not shown) upper spline section.The diameter of the center hole 7 that described ring-shaped step forms is less than the external diameter of the splined shaft of starter motor.
Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.The utility model not only is confined to above embodiment, and its concrete structure allows variation, as: described limit stoper can also be the dentation that circumferentially distributes along spline housing 5 inner peripheral surfaces; Deng.All various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
