-amplitude of this Measuring Time value and schedule time value is compared, if this Measuring Time value in said predetermined amplitude, announces that then wheel box meets.
According to the embodiment preferred of invention, switch for each ratio, measure the phase one of switching; So-called time near the stage, the subordinate phase of switching, the time in so-called synchronization stage; The phase III of switching, the time in so-called engagement stage, if; Switch for different ratio, three time values so measuring each all in corresponding predetermined amplitude, announce that then wheel box meets.
Advantageously, the automatic control wheel box is " small and exquisite automatic control machinery " or MCP type wheel box.
These amplitudes of schedule time value can be by change frequently, particularly with the new reduction gear ratio in the different synchronization time.
Target of the present invention also is to be used for the equipment in its vehicle automatic control wheel box accordance inspection of described inspection method above main line enforcement.
This equipment comprises:
Be used to admit the inspection worktable of the wheel box of examine,
Automat with the inspection worktable interrelates has the function of sending the ratio transfer sequence to the electronic calculator of wheel box,
The electronic data processing parts, the time value that its administrative institute measures also determines the accordance of wheel box or not meeting property.
Preferably, the net by means of CAN (acronym of " controller local area network ") type sends the ratio transfer sequence to the electronic calculator of wheel box.
This equipment is positioned at the end of the hookup wire of wheel box.
At last; Target of the present invention is vehicle; Especially automobile; Wherein the automatic control wheel box comprises that control ratio switches the electronic calculator of gearing, and it comprises the definite integral definite value (consignes fig é es integr é es) that a cover is confirmed said control, and in its main line, checks said wheel box according to the method that conforms to top described method.
Description of drawings
Other purposes, advantage and the characteristic of invention will have in the back in the description of embodiment and occur, and said embodiment is not limited to the target and the scope of present patent application, with accompanying drawing, wherein:
-Fig. 1 schematically representes, according to total structure of the accordance checkout facility of MCP wheel box of the present invention,
-Fig. 2 A, 2B and 2C represent it also is the controlled variable time-varying figure of speed according to the present invention than the switching gearing,
-Fig. 3 is the more detailed figure of Fig. 2 B, and the electric current of the control command of gearing is switched in expression.
Embodiment
About the drawing of Fig. 1, schematically represented be positioned at wheel box assembly line end therefore be case is being mounted on the vehicle before the locational automatic control wheel box of inspection on inspecting stand 2, for example (always the censuring 1) of MCP type.Wheel box 1 is by counter (mark 5) management, and the function of said counter is, especially, thereby thereby the gearing of control box guarantee the gearing of switching and the selection and the solenoidoperated cluthes of ratio and guarantee the open and close of clutch coupling.
Mark 3 is meant the automat that interrelates with inspecting stand 1, and mark 4 is electronic data processing parts of electronic calculator or PC type.
The method that is used to check the accordance inspection of automatic control wheel box 1 comprises the following steps:
-by layout at the automat 3 at this end to electronic calculator 5 transmission speeds of wheel box 1 than the order of switching, symbolically represent like arrow OP with Fig. 1,
-in response to each transfer sequence, electronic calculator 5 control ratios switch gearing, the control of gearing, as Ben Wenben described above, confirm by current ration integration in electronic calculator 5 and that depend on the ratio switching type,
-switch for each ratio, measure the time at least one composition stage of said switching,
-amplitude of this measured time value and schedule time value is compared, if measured time value in said predetermined amplitude, announces that then wheel box meets.
According to the embodiment preferred of invention, measure three different time, it is following time (referring to Fig. 2 B):
The phase one of-switching, the time T A in so-called " near the stage ",
The subordinate phase of-switching, the time T S in so-called " synchronization stage ",
The phase III of-switching, the time T E in so-called " engagement stage ",
If, switch for different ratio, three time value TA, TS and TE so measuring each all in corresponding predetermined amplitude, announce that then wheel box meets.
On Fig. 2 A to 2C, represented the control data of speed than the gearing that switches.
Fig. 2 A has reproduced the curve map Pt of the location P of the gearing that becomes along with time t, promptly between three the stepping threshold values (seuils calib é s) corresponding to disengagement D, neutral position N and engagement E.
Fig. 2 C has reproduced the curve map V (t) of the speed of the first axle of wheel box that becomes along with time t, the speed of the axle that the axis (axe) that promptly exports through clutch coupling and vehicle motor links to each other.Mark Vfs is meant the rotating speed (r é gime) at synchronization end.
The current ration I of gearing control command
tBe the fixedly definite value that becomes with the ratio switching type, it representes on Fig. 3 at Fig. 2 B in more detail, wherein:
-T
0Be the time that ratio is switched beginning,
-T
1Be that gearing is thrown off the leap time of (D),
-T
2Be the leap time of neutral position (N),
-T
3Be that synchronization finishes, main shaft has reached the time of its final speed,
-T
4Be the leap time of engagement threshold value,
-T
5It is the time of ratio finishing switching.
