Abstract
In a motor vehicle, an automatic gear-change device of a change-speed gearbox is connected to a manual selector lever which is arranged in the region of the driver's seat and onto which a mechanical interlock, which can be actuated by an electromagnet, can be caused to act to prevent changing into the reverse gear.
Description
The present invention relates to a kind of like this power actuated vehicle (hereinafter to be referred as automobile), it comprises that one is used for the gearshift of Automotive transmission, it has a manual selector bar that is configured in the operating seat zone, selector rod can switch to the D position of the shift procedure's work that makes to overtake from the N position of blocking-up change-speed box moment of resistance transmission, or switches to the R position that changes reverse gear over to; It also have one by electromagnet promote in case spline is gone into the mechanical interlock mechanism of reverse gear; With the switch that has a control electromagnet at least, the action of this switch and the setting of change-speed box are irrelevant; Described electromagnet is installed in the linking lever and the interlock mechanism of being fixed in last of automobile rotationally by one and links.
(DE3 on the automobile of a known change-speed box with a manually operated mechanical gear shift mechanism, 214.710C3) holding magnet of application, the armature of this magnet and one is placed in the linking lever direct connection on (gear) case of transmission outer wall and drives the interlock mechanism that is placed in the change-speed box successively, to handle gearshift.This armature is controlled by holding magnet by electronic control unit.When the hand shift joystick moves and gain reverse when the moving velocity that advances is too high and will be hindered towards new gear shelves direction.For this purpose, one control signal and control signal that produces by back-up lamp switch by the moving velocity decision, promptly link from the control signal that promotes change lever and logical transition (or switch) unit of a control unit, its connecting mode make have only when the control signal that determines by moving velocity recently when the control signal of gear-shift lever occurs earlier, just can make and hinder effectively, though mention in this publication that in automatic transmission with hydraulic torque converter using this class is that the interlock mechanism of reverse gear setting also is easily, does not provide the corresponding techniques scheme to this application in this publication.
Gearshift of the same type also has description in JP-A 3-239868, can be acted in one second interlock mechanism by solenoid-actuated linking lever, this second interlock mechanism is locked in manual selector rod with respect on the effective selector rod position on the backset plate that is fixed on the vehicle.The blocked mode of manual selector bar is: promptly make selector rod in fact can't move, must throw off manually to make it with the button that is positioned on the manual selector bar handle, go so that promotion manual selector bar enters in one of other selector rod active position in all cases.
DE 3,744, and the difference of the gearshift of 761A1 and gearshift of the same type is that electromagnet is not to be attached on the interlock system by the rotating linking lever that is installed in a part that is fixed on the automobile.The one second same interlock mechanism is also arranged in this known gearshift, this interlock mechanism is fixed on manual selector rod with respect to one and is fixed on the effective choice device bar position of the backset plate on the vehicle, and selector rod is in such a way by the lock locking; Promptly make selector rod in fact can't move, and must make it to break away from, enter into one of other effective choice device bar positions in all cases so that promote to design selector rod divided into two parts by the expansion link form.This action is partly implemented by pushing expansion link.This expansion link partly has leader and to be engaged on interlock pin in the backset plate with respect to expansion link another part, and expansion link another part is installed in rotation on the drive tab and gets on by the gearshift that a connecting rod is attached to change-speed box.The thread bush mould is annotated on the expansion link part that is rotatably mounted, and can be screwed into electromagnet in the thread bush.A lock pin is molded on the electromagnet armature part.When above-mentioned interlock mechanism was pushed, this lock pin was engaged in the corresponding transverse holes of the expansion link with leader and second interlock mechanism's lock pin.One to be in the P position with manual selector rod still be that the switch that moves of N position can directly be provided with on the automatic transmission with hydraulic torque converter or on expansion link mechanism.
Two kinds of above-mentioned gearshifts need two interlock mechanisms in case change reverse gear in to overtake, but the cost of production height of these gearshifts is easy to break down.
The objective of the invention is to propose to be installed in the gearshift on the automobile with automatic transmission with hydraulic torque converter, it is by electronic controller controls and have for the manual chosen position R of reverse gear and set the position P of mechanical interlock for parking, this gearshift is the effect by the interlock mechanism of moving greater than a given threshold value in the speed of a motor vehicle, prevent the vehicle R position that selection should not be selected in to overtake or reach the P position because of carelessness, in this case, interlock mechanism should be different and independent with the similar interlock mechanism that arranges in the change-speed box space, and have the little and lightweight characteristics of size.
That explains above is embodied its preceence according to the feature of this purpose of the present invention by Patent right requirement 1.
By in the automobile involved in the present invention, the mechanical part of interlock mechanism, electromagnet,, some parts that produce from the switch contact of the control signal of selector rod action and import the finder mechanism of manual force when selecting into are contained on the small and exquisite frame of device easily for all collecting.This frame or be positioned in the change-speed box passage or in the gauge panel, or at the diverse location place in crew module's operating seat zone, therefore applicable to different automobile types, different engine type and various deployment scenarios.
By automobile of the present invention, those parts of manual force are imported into not only by the direct locking of the Machinery Ministry of interlock mechanism in finder mechanism in selection course, and direct pull switch is to form relevant control signal, promptly finish the double function of locking and formation signal at same position, in other words manual force is imported into to the finder link gear and gone, make tolerance and other tolerances to be installed and to handle finder mechanism improperly not make interlock mechanism transship.
By automobile of the present invention, be achieved assembling in advance by the device frame, adjust linking lever and electromagnet line position by being provided with of Patent right requirement 2 with respect to the setting shaft axle that rotates.It is nonconforming promoting the manual selector bar towards the R locality.Very big to effect on the mechanical part of interlock mechanism in this case power, this has to be weakened expediently by the layout by Patent right requirement 3～5 by the power of device frame buffering, so device frame itself can be made by steel plate by plastics Cheng Erduan screen.In self-propelled vehicle, electromagnet is installed according to Patent right requirement 6 vertical direction of the present invention, except the acceleration/accel that produces along vertical axis, nearly all edge laterally, vertically, the acceleration force that produces on the pitch orientation all can not influence electromagnet.According to the measure of Patent right requirement 7, extra check Patent right requirement 6 interlock mechanism's end positions fixing and between armature of electromagnet and linking lever the project organization of radial type simplified.

The excitation of linking lever 22 by electromagnet 19 is pushed and enters its interlocking position 121, and this position is corresponding to the extended position 118 of electromagnet 19 strokes.
The effect of pallet 59 is in fact to make linking lever 22 clips on releasing position 58 with respect to end screen 39, in order that fundamentally chatter sound can not take place.When linking lever 22 is pushed when entering its interlocking position 121, consequently be difficult to the effect that driving pawl lever 78 oppositely overcomes spiral tension spring 81 owing to the setting power of electromagnet 19 is too weak, so between setting shaft 26 and pallet 59, be provided with an ACTIVE CONTROL with cam-controlled 70 forms, thereby can make interlock mechanism 18 shifting out from its releasing position 50 and enter as shown in Figure 4 interlocking position 60 as shown in Figure 2 so that between pallet and linking lever, produce a clear passage.Cam-controlled mainly coorespondingly is the reverse control cam 89 that the roller form is installed in rotation on the pallet lever 78 and forms at the control cam 88 that includes some cam areas on the face cam 55 and by one, oppositely controls cam and rolls on the control cam and slip away.
Consult Fig. 7 especially, control cam 88 comprises a cam areas 91 that is made of a surface, this surperficial center of circle is coaxial with the rotation axis 41-41 of setting shaft 26, lean with reverse control cam 89 under the effect of spiral tension spring 81 by means of this cam areas 91, pallet lever 78 can be fixed on pallet 59 and stop portion 63 between the relevant engage position 94 (Fig. 2) of engagement, and can be fixed on pallet 122 and stop portion 126 between the relevant engage position 133 (Fig. 6) of engagement.
The control cam has a cam areas 97, the edge is with respect to rotation axis 41-41 left-hand revolution direction cam areas 97 and cam areas 91 adjacency, cam areas 97 with respect to cam areas 91 have a lift be used for promoting being in engage position 94 or 133 and free-running operation position 71 (Fig. 4) between pallet lever 78, no matter linking lever 22 is to be in releasing position 58 or interlocking position 121, the stop portion jump out of mesh that pallet 59 and 122 all is mated in free-running operation position 71.
Moreover, control cam 88 has a cam areas 104, along with respect to rotation axis 41-41 left-hand revolution direction cam areas 104 and cam areas 101 adjacency, cam areas 104 is the pallet levers 78 that are used for promoting to be between the engage position 94 and 133 separately of free-running operation position 71 and pallet 59 and pallet 122.Cam areas 104 is made of a cam face that is positioned at the plane 179-179 that is parallel to rotation axis 41-41, the stroke of cam face is: the C1 point on contiguous cam areas 101 planes to the distance R 1 of rotation axis 41-41 greater than away from the distance R 2 of the point of the C2 on the plane of cam areas 101 to rotation axis 41-41, in order to reach engage position 94 and 133 reliably, distance R 2 is less than the radius of cam areas 91.By means of the stroke 179-179 of cam areas 104, interlocking nose 53 and cam areas 104 are positioned at a plane perpendicular to the setting shaft 26 of rotation axis 41-41, and control cam 88 and interlocking nose 53 are formed at also constitutes one with it on the relative face cam 55 that approaches.
Fig. 7 also shows the particular design of stop portion 126, it with the throw of lever 75 that is positioned at linking lever 22 on and cooperate collaborative work with the pallet 122 of the interlocking position 121 that is used for linking lever 22, thereby there is a surperficial formed stop district 137 that is positioned at plane 140-140 stopper section 126.Moreover, there is the receiving channel 144 of a flute profile in stop portion 126, its edge is with respect to the clockwise direction and stop district 137 adjacency of the pivot axis 85 of linking lever 22, the circular arc that the geometric configuration of receiving channel is suitable for pallet 122 cooperates, and its present position is slightly offset along the direction of pivot axis 85 with respect to the plane 140-140 parallel with pivot axis 85.
The subordinate list that the functional mode of interlock mechanism 18 (or operating mode) can be consulted Fig. 9 is described below:
If moving velocity is lower than the threshold value of 8km/h, interlock mechanism 18 is in its releasing position 50, as Fig. 1 c, shown in 2,3 and 8.Correspondingly selector rod is on all positions of its releasing position 58, there is a bigger distance 62 in the stop portion 52 on the linking lever 22 under the state of releasing position of interlock mechanism 18 of being in apart from the rotation axis 41-41 of setting shaft 26, and this distance 62 can make the interlocking nose 53 on the setting shaft 26 remain free released state with respect to linking lever 22.
If under the state of these shelves that are not obstructed, when the instantaneous position 72 of selector rod 14 is in the angular range 72 of the position 1-2-3-4/D that is included as to overtake, the reverse control cam 89 of pallet lever 78 and cam areas 91 engagements, thus be used on pallet 59 and the linking lever 22 of releasing position 58 of linking lever 22 cooresponding stop portion 63 be meshed (engage position 94).
If under the without hindrance shelves state of interlock mechanism 18, when the instantaneous position 72 of selector rod 14 is in the angular range 98 between its D position (with respect to the angle initialization 115 of rotation axis 41-41) and N position (with respect to the angle initialization 113 of rotation axis 41-41), the reverse control cam 89 of pallet lever 78 is meshed with cam areas 97, thereby pallet lever 78 is pushed and enters a midway location (Fig. 3) between engage position 94 and free-running operation position 71.
If under the without hindrance shelves state of interlock mechanism 18, the instantaneous position 72 of selector rod 14 is in adjoining angle scope 98, in rotational direction point to corresponding to the angle initialization 116 of R position and comprise corresponding in the angular range 169 of the angle initialization 113 of N position the time, oppositely control cam 89 is meshed with cam areas 101, thereby pallet lever 78 is pushed and enters its free-running operation position 71, in this position, pallet 59 and 122 enough big apart from the distance 64 of the rotation axis 41-41 of setting shaft, thus linking lever 22 all is freely in its all positions with respect to pallet.
If this angular range 105 was in abutting connection with angular range 169 and comprise corresponding to the angle initialization 116 of R position with corresponding to setting the angle initialization 114 of interlock mechanism in a P position of the selector rod of parking when the instantaneous position 72 of finder lever 14 was positioned at the angular range 105 of setting shaft 26, oppositely control cam 89 is meshed with cam areas 104, so pallet lever 78 or be in engage position 94, or be in the midway location between engage position 94 and free-running operation position 71.
If at first moving velocity surpasses the threshold value of 8km/h and when selector rod 14 is stayed angle initialization 115 corresponding to the D position subsequently, linking lever 22 is only promoted by electromagnet 19 and enters its interlocking position 121, as Fig. 4 and (this moment, the interlocking portion 52 of linking lever 22 was littler apart from the distance of rotation axis 41-41 than interlocking portion 52 when the releasing position 58 apart from the distance 65 of the rotation axis 41-41 of setting shaft 26) shown in Figure 6.
Leaving this angle initialization 115 at the selector rod 14 that is positioned at angular range 92 and be pushed under the situation, thereby electromagnet 19 disconnects the excitation interlocking and eliminates again when the P PARK Position P that advances has arrived along the forward position of adjacency.
Be pushed towards the direction corresponding to the angle initialization 113 of N position at selector rod 14 and just leave under angle initialization 115 (D position) situation, electromagnet 19 still keeps excitation when angle initialization 113 has reached, thereby produces Interlock Status 60 as shown in Figure 4.So selector rod 14, has prevented any direction towards corresponding to the angle initialization 116 of R position that is not allowed in the case owing to interlocking nose 53 and interlocking portion 52 form mechanical blockage and has been continued promotion.
The selector rod of in the end being narrated 14 is pushed from angle initialization 115 and enters as shown in Figure 4 Interlock Status 60, control cam 88 arrives angular range 169 through angular range 98 backs, consequently, pallet lever 78 by its oppositely control cam 89 at first be by cam areas 97 promotion freedom of entry run locations 71, to be fixed on the free-running operation position 71 by cam areas 101 (Fig. 4) at last from its engage position 133 (engage position 133 is with respect to pallet 122 and the engagement (Fig. 6) between the stop portion 126 relevant with interlocking position 121).
In Fig. 5 and Fig. 7, the following mode of operation of interlock mechanism 18 also will be narrated:
If when moving velocity promotes the direction of selector rod 14 towards the R position greater than attempting under the threshold value situation, chaufeur must promote selector rod 14 towards the D locality, because attempting to change reverse gear like this gets clogged, under the situation of the direction gear shift of N position, linking lever 22 remains on free state with respect to pallet lever 78, depend on moving velocity, electromagnet 19 can be to keep foment or be disconnected excitation.When finder 14 when move backward in the D position, oppositely control cam 89 rolls along cam areas 97, yet electromagnet 19 only just cuts off the power supply when arriving the D position, because do not occur causing electromagnet 19 to disconnect the available signal of excitation on the control unit 24 before this.So the pallet 122 on the pallet lever 78 touched in the stop district 137 that is resisted against linking lever 22 before stop district 137 can be back to its releasing position 58.If the contraction spring restoring force of electromagnet is too small when the application force of linking lever 22 resistance pallet levers 78 is gone back to, that not linking lever 22 just rest on existing position.In the case, move into a fixing position 121 for making linking lever 22, stop district 137 is arranged on the linking lever 22.Be used for and pallet 122 contacted stop districts 137, its surface is positioned at the plane that is limited by two straight lines, wherein straight line and pivot axis 85 are parallel and another straight line and pivot axis 85 are perpendicular, and tilt towards rotation direction with respect to the contact point tangent line between linking lever 22 and the pallet lever 78, pallet lever 78 rotates towards the direction opposite with the rotation direction 142 that discharges linking lever 22.By means of stroke with respect to the plane 140-140 that rotates the arc face tilt, pivot axis 85 around linking lever produces a moment M1=F1 * F1 on linking lever 22, wherein power F1 equals pallet lever 78 application forces in stop district 137 by 31 of the effects of spiral tension spring 81, L1 equals the F1 line of action of force to the distance between the pivot axis 85, there is a moment M2=L2 * L2 to act on the linking lever 22 with the rotation direction 142 of moment M1 is equidirectional, wherein F2 equals the spring convergent force of electromagnet 19, and L2 equals the active line of power F2 to the distance between the pivot axis 85.Act on friction force R between linking lever 22 and the pallet lever 78 and produce a moment M3 around the pivot axis 85 of linking lever 22, this moment M3 is opposite with the M2 action direction with two other moment M1.Integrate and on linking lever 22, form a neutral equilibrium state, the disturbing influence that this jolts in the time of can being subjected to travelling on uneven road surface, according to the present invention by means of the stroke that is the plane 140-140 in stop district 137, linking lever 22 is set at not slack-free releasing position 58 in this case, be that pallet 122 can fall in the flute profile receiving channel 144, consequently linking lever 22 be firmly held in one with the slightly different second interlocking position 121* of interlocking position 121 on, until selector rod 14 further from the D position after the N position promotes, linking lever 22 is just discharged by the pallet lever.By the promotion of electromagnet 19, connection is determined in moving velocity linking lever 22 or is entered its releasing position 58 or enter its normal interlocking position 121 subsequently.
