Briefly set forth the process of clutch combination below in conjunction with Fig. 3: the combination of clutch will be divided into four-stage: the idle stroke stage, overcome resistance stage, boost phase, no cunning and rub the stage.
The idle stroke stage is used to eliminate gap between clutch plate, no transmission of torque.AB section in the corresponding diagram 3 is from reducing the time consideration of gear shift interruption in power, the combination fast of this stage.Overcome to produce between the master and slave moving plate of resistance stage internal clutch to slide and rub, but the torque of clutch transmits can't overcome the maximum rolling resistance moment of automobile, vehicle relies on inertia to continue to travel.This stage does not influence the car load situation, and the cunning that but can produce clutch is rubbed, the BC section of corresponding diagram 3, this stage should be fast in conjunction with to reduce unit friction work.During boost phase between principal and subordinate's moving plate of clutch torque transmitted surpass maximum rolling resistance moment.The variation of the moment of clutch transmits can cause impact, so the slowly combination of this stage, to obtain gear shift stably, improves occupant's riding comfort and reduces the power train impulsive load.Combination time can not be long simultaneously, otherwise because sliding friction time is oversize, causes clutch overheated, and influence its life-span, the CD section in this stage corresponding diagram 3.Clutch principal and subordinate, moving plate began synchronously when the nothing cunning was rubbed the stage, the acceleration of automobile and shock extent all depend on the output button square of motor, and there is not unit friction work, because this moment, the combination of clutch did not have influence to property of automatic shft, therefore consider from finishing gear shift as early as possible, the combination fast of this stage, the DE section in this stage corresponding diagram 3.B point among the figure is the clutch half hitch chalaza of corresponding A MT vehicle.
By above analysis as can be known, the cohesive process of whole gear shift sleeve is the cohesive process of " fast-slow-fast ".Tf is the resisting moment that is converted to transmission input shaft among Fig. 3.TC is the carry-over moment of clutch.
By above-mentioned analysis as can be known, the judgement clutch half hitch chalaza apparatus structure that is used for the AMT vehicle of the present invention is reasonable, functional.Test result has also shown correctness and the rationality of judging clutch control.Thereby the smoothness of gear shift and the control performance of vehicle have been improved.Also the transformation for the AMT automatical control system provides comparatively practical method.
