The present invention relates to the automatic transmission of conical pulley flexible drive transmission form, for example disclosed by DE 102004015215 and other open source literature, and relate to method that is used for its manufacturing and the Motor Vehicle of equipping it.
Background technique
Automatic transmission is a specific character torque-converters (Kennungswandler) on wider meaning; Its current gear ratio automatically according to the working state of current or expectation, like partial load; Propelling and enviromental parameter, like temperature, air pressure, humidity of the air have level ground or infinitely change.Belong to the such characteristic torque-converters of having of it: pneumatic based on electronic, fluid power, the principle of hydrostatic pressure or based on the characteristic torque-converters of the principle of the mixing of these principles.
Automation then relate to different functions, as the starting; Gear ratio is selected; The mode that gear ratio changes in the different operating state wherein for example can be regarded as each retaining level for shifting gears of gear ratio and one after the other changes, changes the saltus step of retaining level and the speed of adjusting.
Confirmed the degree of automation in other words, have how many functions automatically to carry out for the requirement of travelling comfort, reliability and selectable construction cost.
Usually the driver can manually intervene the operation of automation or it is limited on some individual features.
Mainly employed in Motor Vehicle is made as now, automatic transmission in a narrow sense has following structure usually:
The starting unit that has a can regulate clutch form at the driving side of speed changer, the friction clutcch of wet type or dry type for example, the clutch of fluid power or fluid torque converter.
Usually be connected a bridging clutch with pump and turbine part for fluid torque converter, this bridging clutch has improved efficient and has come damped vibration through the slip of confirming when the critical revolution through direct power transmission parallelly connectedly.
Starting unit drives a machinery, stepless or the speed change gear of level is arranged, and this speed change gear can comprise the unit that moves ahead/move backward, and main group, a zone are organized, fast block group (Splitgruppe) and/or a stepless speed variator.The gear-shift transmission group is looked running stability, position situation and transmission possibility and is designed to have the middle shaft type or the planetary structure of straight-tooth or helical teeth surely.
The output block of mechanical transmission; I.e. axle or direct geared ground or drive a differential transmitting linkage indirectly through jack shaft or intergrade with constant gear ratio, this differential transmitting linkage can be used as independent transmission device and constitutes or an integrated constituent element of automatic transmission.This speed changer is suitable for the vertical and horizontal installation on Motor Vehicle in principle.
For the gear ratio of regulating mechanical transmission can be provided with hydrostatic pressure, pneumatic and/or electronic actuator.Be provided for the pressure oil of starting unit, especially hydraulic power unit according to the oil hydraulic pump of extrusion principle work, be used for the pressure oil of the lubricated and cooling hydrostatic pressure executive component and that be used for system of mechanical transmission.Look required pressure and delivery volume and can consider gear pump surely, volute pump, vane pump and reciprocating pump, the latter is generally the radial structure mode.Use gear pump and radial piston pump for this purpose in practice, wherein gear pump is because its construction cost is little and radial piston pump has advantage owing to its stress level height and controllability are good.
Oil hydraulic pump can be arranged on the arbitrary position of speed changer and on a main shaft or countershaft that is continued to drive by driver element.
Disclose stepless automatic transmission, it is made up of a starting unit, conduct move ahead/the move backward reversible transmission device of planetary pinion (Planetenwendegetriebe) of unit, an oil hydraulic pump, a stepless speed variator, a jack shaft and differential mechanism.Stepless speed variator is made up of reaching a winding contact device two awl dishes again.Each awl dish is to comprising second an awl dish that can move in the axial direction.Twine contact device these awl dishes between operation, this windings contact device for example can be propelling crawler belt (Schubgliederband), tow chain or belt.The operating radius that twines contact device through the mobile change of the second awl dish reaches the gear ratio that changes stepless automatic transmission thus.
ST needs high stress level, so that the awl dish of stepless speed variator can be adjusted on all working point with required speed, and does not have wearing and tearing ground transmitting torque as far as possible with enough basic compaction pressure in addition.
In Motor Vehicle, the requirement of travelling comfort is very high usually, also relates to acoustic connection particularly.Especially automobile driver and occupant do not hope noisy noise in the Motor Vehicle of top grade, and these noises are that the work by the unit of Motor Vehicle forms.Yet internal-combustion engine and other unit such as speed changer produce noise, and these noises can be used as to a great extent to disturb and are felt.For example in the infinitely variable speed changer, use under the situation that connects leaf chain to cause noise, because this connection leaf chain is because the structure of its connecting plate and pin is bumped the impact that on the awl dish of speed changer, produces repetition through pin in speed changer work.Acoustic effect gets into (" impact ") owing to the pin as excitation source usually in the CVT speed changer.This acoustic excitation then produces resonance on the natural frequency of case of transmission (FE model (FE-Moden)) or axle (reversing mould (torsionale Moden), bending die (Biegemoden)).
Another acoustic effect is from the CVT chain, and this chain can produce vibration on section that clamps or reversion Duan Ruyi side, and this for example can prevent through slide rail.The tearing when frictional vibration that reverses for example is known as frequency from clutch and is 10Hz.When being changed to friction factor and descending of friction factor under slippage change situation, will motivate and tear.At first steel-paper friction factor is important relevant on automatic transmission.

Embodiment
Fig. 1 only illustrates the part of a conical pulley flexible drive transmission, i.e. conical pulley flexible drive transmission 1 by a driving motor, for example oil-engine driven driving side or input side part.In a conical pulley flexible drive transmission that intactly constitutes to this input side partly disposed the infinitely variable conical pulley flexible drive transmission, a slave end part that complementally constitutes, wherein these two-part are connected to each other with transmitting torque through a winding contact device that for example connects leaf chain 2 forms.This conical pulley flexible drive transmission 1 has an axle 3 at input side, in an illustrated embodiment this axle and a fixing awl dish or decide awl dish 4 and constitute integratedly.Should axially go up fixing awl dish 4 axle 3 axially on be adjacently located on the moving awl dish of an axially-displaceable or the opposite of mantle dish 5.
In view according to Fig. 1; Connect leaf chain 2 and be indicated on driving side awl dish 4; On the radially outer position on 5; This position obtains like this, promptly moves on the moving awl dish of axially-displaceable 5 direction to the right in the figure and this axial displacement campaign of the awl dish 5 that axially-displaceable is moving causes connecting leaf chain 2 and on the direction of radially outer, moving, and the gear ratio of speed changer is changed to fast.
The moving also available known mode of awl dish 5 of axially-displaceable own is moved to the left in drawing; Wherein in this position, connect leaf chain 2 and be positioned at (with label 2a indication) on the inner radial position, the gear ratio of conical pulley flexible drive transmission 1 changes at a slow speed on this position.
The torque that is provided by a unshowned driving motor imports the driving side part of the conical pulley flexible drive transmission shown in Fig. 1 through a gear 6 that is bearing on the axle 3; This gear 6 is bearing on the axle 3 through the rolling bearing of ball bearing 7 forms of a bearing radial force and axial force, and this ball bearing is fixed on the axle 3 through a back-up ring 8 and a spindle nut 9.Between the moving awl dish 5 of gear 6 and axially-displaceable, be provided with a torque sensor 10, this torque sensor disposed the support plate configuration 13 of the moving support plate 12 of a support plate 11 that is provided with axial restraint and axially-displaceable.Between two support plates 11,12, be provided with some rolling elements, for example shown in the rolling element of ball 14 forms.
The torque that imports through gear 6 cause fixing in the axial direction support plate 11 with axial on a rotation angle between the support plate 12 movably; This will cause an axial displacement of support plate 12; Exactly owing to be arranged on some starting inclined planes on this support plate, ball 14 ascending motions reach and are used for support plate axial dipole field each other thus on these inclined-planes.
Torque sensor 10 has two pressure chambers 15; 16; Wherein first pressure chamber 15 is provided to be used for load with pressure medium and second pressure chamber 16 is supplied to pressure medium according to the torque that imports, and exactly the gear ratio according to speed changer is supplied to pressure medium.
Be provided with a piston/cylinder unit 17 in order to produce impacting force, by this impacting force the awl dish 4 of axial restraint loaded a normal force with the leaf chain 2 that is connected between the moving awl dish 5 of axially-displaceable, this piston/cylinder unit has two pressure chambers 18,19.First pressure chamber 18 is used for changing the loading that connects leaf chain 2 according to gear ratio; And second pressure chamber 19 is used for increasing with interrelating or reduce impacting force with the pressure chamber 15 according to torque control of torque sensor 10; Connection leaf chain 2 between the awl dish is to 4,5 is loaded by this impacting force.
For to these pressure chamber's supply pressure media, axle 3 is provided with three passages 20, is fed in these pressure chambers through these passages from the pressure medium of a unshowned pump.Can and be input to circulation loop again by axle 3 outflows through passage 21 pressure mediums of discharging side.
Pressure chamber 15,16, on axle 3, move relevant of the awl dish 5 that 18,19 loading will cause axially-displaceable to move with torque and gear ratio.In order to receive movably awl dish 5, axle 3 has some centering faces 22, and these centering faces are used as the movably seat that is slidingly matched of awl dish 5.
As obvious through Fig. 1, conical pulley flexible drive transmission 1 has a noise damping device 23 respectively in the zone at these supporting positions of axle 3 epicone dishes 5.This noise damping device can have an annular solid and a damping lining or only be made up of a damping lining for this reason.
Employed label is also to the characteristic that in other accompanying drawing, can contrast among Fig. 1.These accompanying drawings should be considered as the unit in this respect.For the sake of clarity, in other accompanying drawing, only use and exceed the label beyond the label among Fig. 1.
In Fig. 2, the center-aisle of present three passages 20 constitutes with the form of relative Fig. 1 remodeling; Can find out that the hole 24 that constitutes central passage 20 is done shortlyer than the center hole among Fig. 1 significantly, this hole 24 processes from the side shown in the right side of Fig. 1 and 2 as blind hole.This blind hole is cost height and the exigent precision of work in-process on making.Its manufacture cost reaches and increases in requirement aspect the course of working reliability and the ultra direct ratio of its length ground in the case.Therefore the shortening in this hole brings favorable influence to manufacture cost.
In the bottom section in this hole 24, divide expenditure a transverse holes 25, wherein also can have a plurality of transverse holes to be arranged on the circumference with distributing.This transverse holes 25 is configured to radial hole in the illustrated case, but it also can other angle be made into inclined hole.Axle 3 surface is passed in hole 25 on a position, this position and working state, promptly for example irrespectively be arranged in a zone with the gear ratio that adjusts, and this zone is all the time by 5 coverings of mantle dish.
Through making axle 3 done shortly in the axial direction in the overlay area that transverse holes 25 is arranged on mantle dish 5, can save structure space thus.What the shortening through axle 3 also can obtain loading in addition reduces.
Here, the outlet of passage or transverse holes 25 for example can be set in the zone of the turning groove 26 adjacent with the centering face 22 of axle.When with the moving ground of mantle dish 5 axially-displaceables but do not have the toothing 27 that is connected with axle 3 for example because transmitting torque when receiving high load, work is particularly advantageous like this with relatively rotating.
But in many cases, the load of toothing 27 is not the design criteria of a key, and the outlet in hole 25 can be set in the zone of this toothing, as shown in Figure 2 thus.Obtain an advantage in the turning groove 26 in the following manner through transverse holes 25 being arranged on replace in the toothing 27 to be arranged on, a bigger drag torque is promptly arranged, the flexural stress in the edge fiber is reduced through it.When the crucial fiber that receives transverse holes 25 interference was maintained on the roughly the same radius, the face rotary inertia on this position was bigger in addition.Obtain obviously reducing of stress in the key area around the outlet of the transverse holes 25 between the tooth of toothing 27 thus.The supply of hydraulic fluid is identical in Fig. 1 and 2, because pressure chamber 15 and 19 forms connection each other and mantle dish 5 has some attachment holes 28, these attachment holes make the zone of toothing 27 be connected with pressure chamber 19.Mantle dish 5 is indicated in the position on its outermost left side in these figure, and this position is corresponding to starting gear ratio or low retaining (Underdrive).If mantle dish 5 moves on the direction of deciding awl dish 4 to the right now, then the part of cavity or chamber 29 always is positioned in the outlet of transverse holes or passage 25, so that also as among Fig. 1, can guarantee required flow supply all the time.Also as among Fig. 1, obtain two transition statuses for pressure chamber 16, these transition statuses are relevant with the axial position of mantle dish 5.Shown in the position in control hole 30 expose, make thus with it form is connected, by a stopper 31 axially the passages 20 of sealing reach and form pressure chamber's 16 decompressions that are connected or only have external pressure through a unshowned passage and it.If now mantle dish 5 moves towards the direction of decide awl dish 4, then it will move on these control holes 30, wherein, from certain stroke chamber 29 be positioned at control hole 30 outlet above.But in chamber 29, have a high pressure relevant with torque, this high pressure also enters in the pressure chamber 16 through control hole 30 and passage 20 then, makes the there also add high pressure thus.Realized two transition statuses in this way, these transition statuses and gear ratio are controlled impacting force relatively.
Be provided with a belleville spring 32 among this external Fig. 2; It makes mantle dish 5 move on on the predetermined axial position under speed changer 1 pressure-less state; Can regulate speed changer 1 gear ratio thus, this gear ratio can prevent excessive load, for example when the Motor Vehicle trailer.
Two plotted curves shown in Fig. 3, they illustrate change curve relevant with contact pressure, the friction factor relative sliding velocity.Here reach in expression Sliding velocity on the abscissa and on y coordinate, represent friction factor.Dotted line is counted as reference value and represents a friction factor, and it for example can be on about μ=0.12.As appreciable by these two figure, friction factor is the function of Sliding velocity, and wherein this friction factor is tending towards along with the increase of Sliding velocity descending.
As stated, the friction factor that for example in clutch, descends along with the growth of Sliding velocity will cause tearing and causing thus the decline of travelling comfort.Therefore try hard to make the decline of friction factor on whole speed to keep as much as possible little.
Curve shown in Fig. 3 appear at chain some swing casting dies and awl dishes and their coefficient surface of contact between point of contact on.Chain twines contact device in other words and both on traffic direction, loads through torque to be passed in the case, also mainly on transverse to the direction of traffic direction loads through impacting force.Here this impacting force should be selected like this, and torque promptly to be passed can be delivered on another awl dish group with enough reliability antiskids with changeing.
The dispersion width of the friction factor that the respective representative of these curves on the y coordinate direction is relevant with impacting force or contact pressure.Contact pressure that the line here is corresponding low and the top corresponding high respectively contact pressure of line.
Through according to existing form of implementation upper curve figure, so far with can see significantly according to comparison lower curve figure, form of implementation of the present invention: at first each is diminished by discrete areas of two curve limits, obtains friction factor thus and diminishes with the contact pressure that has just applied or the dependence of impacting force.In other words, insensitive according to the variation of the relative contact pressure of form of implementation of the present invention (lower curve figure).
Can be seen also that by Fig. 3 the curve among the lower curve figure more flatly extends, and obtains thus: the coherence of friction factor and Sliding velocity diminishes.Can reach the more stable properties of friction factor through this smooth negative gradient of friction factor relative sliding velocity.In the case when these curve approximations from the top down or oppositely move abreast than when their change problems on its slope littler because the change of any slope represents the coherence of friction factor and Sliding velocity bigger.
Change curve that confirm so clearly, the friction factor relative sliding velocity shown in lower curve figure among Fig. 3 and relative contact pressure can produce the inhibition to vibration, and this vibration is to inspire through the friction factor variation that steel-steel between band or chain and the awl dish contacts.Through using a kind of corresponding oil to change and directly to overcome this vibration in the place that vibration occurs by a kind of like this friction factor.
Plotted curve among Fig. 4 basically as the plotted curve among Fig. 3 set up, but the former is provided with the coherence that illustrates with employed oil, but the coherence with the surface characteristics value is shown.The explanation that the explanation of making in conjunction with Fig. 3 reaches about improving is equally applicable to Fig. 4, that is to say the major improvement of the clear situation of lower curve chart.
The upper curve of Fig. 4 illustrates a situation on the polished surface, and the lower curve figure of this figure is illustrated in the coherence according to friction factor and Sliding velocity and contact pressure under the situation of surface characteristics value of the present invention.These surface characteristics values for example can produce through a kind of polishing processing, and wherein friction parameter has correct change curve and it can be held on long working time.For example on smooth surface, the noise phenomenon can be occurred immediately, and how also noise can be do not occurred during in best situation under the state of rough surface.This improvement of noise properties aspect also can realize through the reduction of impacting force or contact pressure.
Test by simulation calculation and measurement shows, can active influence be arranged to vibration characteristics and noise properties through the tumble raising of rigidity of axial movable awl dish or mantle dish, wherein this situation especially-but not exclusive ground-the be suitable for mantle dish of slave end.Always obtain, the resistance to flexure of raising-by it can reduce the awl dish, especially slave end awl dish group opens-can reduce noise is produced the vibration amplitude that significant relationship is arranged.Similarly effect can reach through the damping that improves on this position.

Mantle dish 33 according to Fig. 5 b has a kind of configuration, and the zone that the radially outward of mantle dish 33 is stretched in this configuration is strengthened in this wise, and promptly its wall thickness increases towards radially outer ground.This will reach through the respective configuration of carrying the profile that twines contact device 2 of awl dish.Here the represented lasting variation of this profile is modification in this wise also, and promptly wall thickness divides a plurality of stages ground to increase.
In order to strengthen mantle dish 33 in the axial direction, also can be provided with one and strengthen bulge loop 35, shown in Fig. 5 c at radially outer.Fig. 5 d representes except that the reinforcement bulge loop 35 that is arranged on radially outer, also to be provided with another and strengthens bulge loop 36, and the latter is set at radially inner and also can be used as two separating devices between the pressure chamber thus when needed.
