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, the one-way element that prior art is used for automobile starter comprises gear 101 and the star wheel 103 of being with outer step surface 102, described gear 101 is fixed on an end of star wheel output shaft 104, both generally make an integral body, the other end of described star wheel output shaft 104 is in a plurality of rollers 106 are installed in the center hole of an end of star wheel 103, and the other end of described star wheel 103 is the spline housing 105 that inwall is provided with (tiltedly) spline.
During ato unit, the output shaft of the interior motor of starter motor is that (tiltedly) spline on the splined shaft is meshed with the spline housing of one-way element, and simultaneously, gear is meshed with the flywheel of motor.At this moment, the moment of torsion of motor generation passes to motor by one-way element.
There is following defective in the one-way element that is used for automobile starter of above structure: when the flywheel engagement driving of gear and motor, the gear of high speed rotating and flywheel mutual friction meeting mutually produce impurity and dust, and impurity and dust are diffused into an end of one-way element splined shaft easily, and then on the spline attached to splined shaft, and when spline and spline housing engagement driving, these impurity and dust can cause wearing and tearing to spline and spline housing, even spline and spline housing is stuck, the working life of having caused potential safety hazard like this and having reduced this one-way element.
The model utility content
The technical problems to be solved in the utility model is, thereby provides a kind of impurity and dust can avoided attached to the one-way element that is used for automobile starter that causes the wearing and tearing of spline and spline housing to stop potential safety hazard, prolong its working life on the spline.
Technical solution of the present utility model is, a kind of one-way element that is used for automobile starter with following structure is provided, it comprises gear and star wheel, described star wheel is step-like for step surface outside the band that is grouped into by star wheel large-diameter portion branch and star wheel minor diameter part, 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 a spline housing, the outer step surface of described star wheel is provided with the seal ring of flexible material, and the outer peripheral surface of described seal ring is against on the inner peripheral surface of end cap of starter motor.
After adopting above structure, the one-way element that the utility model is used for automobile starter compared with prior art has the following advantages:
Because the outer step surface of described star wheel is provided with the seal ring of flexible material, the outer peripheral surface of described seal ring is against on the inner peripheral surface of end cap of starter motor, so the sealing ring becomes two disconnected cavitys to the separated by spaces in the starter motor end cap, and gear and flywheel friction-produced impurity and dust, blocked by seal ring, can not be diffused into an end of one-way element splined shaft, and then prevented on impurity and the spline of dust attached to splined shaft, avoid impurity and dust that spline and spline housing are caused wearing and tearing, stopped potential safety hazard like this, prolonged the working life of this one-way element.
