Description

Starting arrangement for internal-combustion engine
Technical field
The present invention relates to a kind of according to claim 1 starting arrangement for internal-combustion engine as described in the preamble.
Background technique
DE 197 48 605 A1 have described a kind of starting arrangement for internal-combustion engine, this starting arrangement has the starter pinion that can drive by electric starter motor, this starter pinion can be between the non-working position of pulling back and the engaging position of front that push away and internal-combustion engine gear ring axial adjustment.The axial adjustment of starter pinion moves through electromagnetism starter relay and produces.The actuation movement of electric starter motor is delivered on the live axle of starter pinion by planetary gear mechanism and free wheel device.Free wheel device has drivening piece and the ring that is radially positioned at outside, and wherein, between drivening piece and interior ring, in the wedge track of interior ring, running has column roller.Drivening piece is the load-bearing member for the planetary bearing bolt of planetary gear mechanism, on the interior engaging piece of the internal gear that planetary pinion is fixedly installed in the position of planetary gear mechanism, turns round.Planetary pinion is driven by the sun gear being fixedly installed on the motor drive shaft of starter motor.
For starting arrangement, for position reason, pursue compact mode of execution.In addition, during starting process, should consider that the least possible noise produces.
Summary of the invention
The object of the invention is to, the starting arrangement that utilizes the measure of simple configuration aspects to be used in internal-combustion engine is realized compactly and is realized and reduces noise and produce.
This object utilizes the feature of claim 1 to be achieved according to the present invention.Dependent claims provides suitable improvement project.
According to starting arrangement of the present invention, be used for cranking internal combustion engine and comprise starter pinion, this starter pinion can regulate between the non-working position of pulling back and the front engaging position pushing away, on this engaging position, and the engagement of the gear ring of starter pinion and internal-combustion engine.The adjustment movement of starter pinion preferably produces by electromagnetism starter relay.Adjustment movement is particularly embodied as and is parallel to the longitudinal axis of starter pinion or the axial adjustment motion of spin axis trend, wherein, also considers to have with respect to longitudinal axis in principle the adjustment movement of radial component.Under the engagement with internal-combustion engine gear ring, starter pinion is driven by electric starter motor, and rotatablely moving of starter motor is delivered on the live axle of starter pinion by planetary gear mechanism.
Starting arrangement is configured with the free wheel device in the bang path between planetary gear mechanism and starter pinion in addition.Free wheel device can make motion be delivered to starter pinion from electric starter motor, but in the situation that gear ring is with the rotation speed operation higher than starter pinion after engine starting, this free wheel device disconnects kinematic bang path.
In foundation starting arrangement of the present invention, the freewheel drivening piece of the member of planetary gear mechanism and free wheel device forms a common element of construction.Freewheel drivening piece is the constituent element of free wheel device starter pinion being installed and driving portion's section acting in conjunction of this starter pinion by rolling element and live axle.Live axle has the roller axle collar for this reason or is connected with the roller axle collar, and the described roller axle collar is the constituent element of free wheel device.
Both can consider in principle the mode of execution that the member of planetary gear mechanism and freewheel drivening piece integral type form, also can consider mode of execution independent but member that mutually connect un-rotatably.In independent mode of execution situation, the member of planetary gear mechanism and freewheel drivening piece also directly recline mutually.
The advantage that the member of planetary gear mechanism and freewheel drivening piece are combined into a common element of construction is compact mode of execution.Particularly starting arrangement axially on, can make required structure space reduce.In addition tool is advantageous, also realizes and reduces noise generation.A member by planetary gear mechanism and freewheel drivening piece is integrated or combination, realizes with the motor casing of starter motor or pole shoe and departs from and connects, thereby also reduces the danger of the amplification of resonating.Reduce thus the noise level while handling starting arrangement.
The integrated component of the common and planetary gear mechanism of freewheel drivening piece aptly axial position arranges regularly.Between non-working position and engaging position, regulate the starter relay of starter pinion not act on freewheel drivening piece, but directly act in an advantageous manner axle or the axle collar of starter pinion or starter pinion.The member integrated with it of freewheel drivening piece and planetary gear mechanism and the adjustment movement of starter pinion independently remain on the fixing position of their axial positions, but they can rotate jointly for transmitting the actuation movement of starter motor.Because only starter pinion must be regulated by starter relay in principle, so that the moving quality of as ready reduces and starter pinion can correspondingly be determined size littlely.
According to the advantageous mode of execution of another kind of tool, planetary gear mechanism and freewheel drivening piece form the member of common structure unit as the internal gear formation with interior engaging piece of planetary gear mechanism.On interior engaging piece, rolling has planetary pinion, planet pin to consign to arrange regularly with housing.At this, both can consider the mode of execution that bearing pin can hold and turn round in the bearing of case side, also can consider the mode of execution that bearing pin fixes to clamp and planetary pinion threaded shaft is consigned rotates.
In the mode of execution as internal gear, noise level obviously declines, because the rolling of planetary pinion on the interior engaging piece of internal gear reduces noise and eliminate resonance by the distance of the motor casing with starter motor or pole shoe and amplify.
Planetary pinion is driven by sun gear, and this sun gear is directly placed on the motor drive shaft of starter motor or the end face of armature shaft aptly.Therefore carry out to the motion internal gear, transmitting by planetary pinion from armature shaft and sun gear, this internal gear due to its with the mode of execution of freewheel drivening piece integral type or not relatively turnable connection also make this freewheel drivening piece motion, wherein, freewheel drivening piece drives the roller axle collar connecting with starter pinion by rolling element.
According to the advantageous mode of execution of a kind of tool, relate to internal gear and freewheel drivening piece integral type and form, these two members are arranged on the axial opposed end face of a common ring.Internal gear is in a close side of starter motor, and freewheel drivening piece is in a close side of starter pinion.Can between internal gear and freewheel drivening piece, radially insert spacing wall, this spacing wall preferably forms and internal gear and freewheel drivening piece is separated from each other with described ring integral type.Spacing wall is for the structural stability of member.This spacing wall can be formed with the recessed empty portion that is positioned at center for armature shaft and/or live axle.So for example can make the coaxial armature shaft arranging and live axle through the recessed empty portion in spacing wall or at least with this adjacent setting of recessed empty portion.For example bearing can be arranged in the region of recessed empty portion, and armature shaft and live axle support each other by this bearing, wherein, and can relative rotary motion between armature shaft and live axle.
According to another kind of suitable mode of execution, planetary bearing pin remains on bearing cap, and this bearing cap is arranged on the motor casing of starter motor.When bearing cap needs, can be supported on the housing of starting arrangement by vibration-damped component, particularly in the axial direction, can realize thus further vibration damping and therefore reduce noise level.
