Description
Technical field
The utility model is related to a kind of starter more particularly to a kind of vehicle starters and its drive gear assemblies.
Background technology
With the continuous development of auto industry, the weight of major automobile vendor and terminal client is subject to for automobile perception problems
Depending on the requirement perceived especially for engine is higher and higher, by promoting perceived quality so as to improving product competitiveness.It is modern
Vehicle starts the engine of vehicle usually using electric starter motor, and the electric energy that vehicle battery stores is changed into machine by starter
Tool energy drives the engine of vehicle to operate, engine is started.
It please refers to Fig.1, Fig. 1 is a kind of partial schematic diagram of the vehicle starter of the prior art.As shown in Figure 1, the vehicle
Starter 10 includes motor 11, transmission mechanism and control mechanism, which is mounted in the housing 12 of starter, is used for
Generate turning moment.The turning moment is transferred to the gear ring (not shown) on engine flywheel by transmission mechanism, to drive hair
The bent axle rotation of motivation.
Transmission mechanism mainly include be connected with the output shaft of motor 11 reducing gear 13, by freewheel clutch 14 with
The connected output shaft 15 of reducing gear 13, the drive gear element 16 being set on output shaft 15.Output shaft 15 is rotatable but not
It is axially movable.
Wherein, the forepart of drive gear element 16 is supported in by axle sleeve 17 on the optical axis portion of output shaft 15, and rear portion leads to
Spline part 18 is crossed to couple with the matching spline portion on output shaft 15.Spline part 18 can slide axially compared with matching spline portion (
In the case of spiral key teeth, rotated while spline part 18 slides axially compared with matching spline portion), to realize output
The axial movement of axis 15.This be axially moved is realized by the shift fork 19 of control mechanism.It the middle part of shift fork 19 can be around a pivot
Axis pivots, and the outer end of shift fork 19 can be pushed and pulled by axial direction of the control mechanism approximately along output shaft 15, and the inner end of shift fork 19 is held on drive
Moving gear element 16.Push and pull the outer end of shift fork 19 vertically by control mechanism, so that shift fork is pivoted around the pivot, shift fork
Inner end drives output shaft 15 to move axially (spline part 18 slides axially compared with matching spline portion), so that drive gear element 16
It engages and departs from the gear ring on engine flywheel.
It please refers to Fig.2, the sectional view of drive gear element used by Fig. 2 is Fig. 1.As shown in Fig. 2, the drive gear is first
The metal structure that part 16 is integrated, the shift fork driving portion 121 of gear part 111 and rear portion including forepart, wherein, gear part 111
For being engaged with the gear ring on engine flywheel, shift fork driving portion 121 is equipped with to accommodate the card slot of the inner end of shift fork 19.
According to structure shown in Fig. 2, drive gear element 16 is formed with gear part integral with one another and shift fork driving portion,
This causes the weight of drive gear element to increase.Meanwhile the weight increase of teeth parts 16 causes the electromagnetic wire in control mechanism
The load increase of circle.
In addition, spline part 18 is formed in the rear portion of drive gear element 16, i.e., in shift fork driving portion, and it is close
The rear end face of drive gear element.Therefore, when shift fork 19 drives drive gear element 16 to move forward, matching somebody with somebody on output shaft 15
A part will be exposed by closing spline part, this so that this part (lubricating grease on especially thereon) in matching spline portion is easily done
It is dirty.
Further, since entire drive gear element is made of metal, and when drive gear element rotates, the inner end of shift fork 19
It can be by abrasion.
Occur high humidity phenomenon after snowing due to the domestic north, it is larger in the temperature difference, it is susceptible to frost.At this point, such as
Fruit ice frost is concentrated on starter main shaft, will influence the seating velocity of starter driving gear, so as to be risen after engine start
Motivation drive gear cannot timely return, flywheel is counter to drag starter driving gear abnormal sound noise occur, seriously affect user sense
By.
