For the eight fast double-clutch speed changers that the embodiment of the present invention provides, one embodiment of the invention gives the gearshift logic of sequential upshift and the gearshift logic of sequential downshift, and the state of the S4 of the first input clutch C1 that each gear is corresponding, the second input clutch C2, the first synchronizer S1, the second synchronizer S2, the 3rd synchronizer S3 the 4th synchronizer can with reference to table 1 and table 2.
, can also there is the gearshift logic of jump type downshift in the eight fast double-clutch speed changers adopting the embodiment of the present invention to provide, be described in detail below to the gearshift logic of jump type downshift.In an embodiment of the present invention, when current gear is more than seven grades, gear directly can be down to fourth gear from seven grades; When current gear is more than fourth gear, gear directly can be down to one grade from fourth gear.
The principle of the gearshift logic of jump type downshift is as follows: as can be known from Table 2, when gear is seven grades, the first input clutch C1 is in bonding state, and the second input clutch C2 is in off state.First synchronizer S1 is combined with seven grades of driving gears 71, the second synchronizer S2 and six grade driving gear pre-hung, and the 3rd synchronizer S3 mediates idle running, and the 4th synchronizer S4 is combined with seven grades of driven gears 72.Namely when gear is seven grades, what participate in Power output only has the first synchronizer S1 and the 4th synchronizer S4, and has nothing to do with the second synchronizer S2 and the 3rd synchronizer S3.Second synchronizer S2 and the 3rd synchronizer S3 is irrelevant is in pre-hung state, is seven grades and is down to six grades and prepares, do not participate in Power output.
When gear is fourth gear, first input clutch C1 is in off state, second input clutch C2 is in bonding state, first synchronizer S1 and seven grade driving gear 71 pre-hung, second synchronizer S2 is combined with fourth gear driving gear 41,3rd synchronizer S3 mediates idle running, the 4th synchronizer S4 and third speed drive gear 31 pre-hung.Namely when gear is fourth gear, what participate in Power output only has the second synchronizer S2 and the 3rd synchronizer S3, and has nothing to do with the first synchronizer S1 and the 4th synchronizer S4.First synchronizer S1 and the 4th synchronizer S4 is irrelevant is in pre-hung state, is down to third gear and prepares, do not participate in Power output for fourth gear.
As can be seen here, can seven grades time, by the state of the second synchronizer S2 and the 3rd synchronizer S3, the state that when being set in advance as fourth gear, the second synchronizer S2 and the 3rd synchronizer S3 is corresponding, by the second synchronizer S2 and fourth gear driving gear 41 pre-hung, the 3rd synchronizer S3 is dallied, with reference to table 3.
Table 3
Then when switching to fourth gear for seven grades, the first input clutch C1 is only needed to switch to off state from bonding state, second input clutch C2 is switched to bonding state from off state, due to state corresponding when the second synchronizer S2 and the 3rd synchronizer S3 has been preset as fourth gear, then directly can switch to fourth gear by seven grades.
As can be known from Table 2, when gear is fourth gear, the first input clutch C1 is in off state, and the second input clutch C2 is in bonding state.Second synchronizer S2 is combined with fourth gear driving gear 41, and the 3rd synchronizer S3 mediates idle running.First synchronizer S1 and the second synchronizer S2 is all in pre-hung pattern, and when namely gear is fourth gear, what participate in Power output only has the second synchronizer S2 and the 4th synchronizer S4, and has nothing to do with the first synchronizer S1 and the 4th synchronizer S4.
When gear is one grade, the first input clutch C1 is in bonding state, and the second input clutch C2 is in off state.First synchronizer S1 is combined with one grade of driving gear 11,3rd synchronizer S3 mediates idle running, 4th synchronizer S4 is combined with third gear driven gear 32, and what namely participate in Power output only has the first synchronizer S1 and the 4th synchronizer S4, and has nothing to do with the second synchronizer S2.
As can be seen here, can when fourth gear, the state that when state of the first synchronizer S1 being set in advance as a grade, the first synchronizer S1 is corresponding, with reference to table 4.
Table 4
When then fourth gear being switched to one grade, the first input clutch C1 is only needed to switch to bonding state from off state, second input clutch C2 is switched to off state from bonding state, due to state corresponding when the first synchronizer S1 has been preset as a grade, and the state that the state of the 4th synchronizer S4 is corresponding when being also a grade, then directly fourth gear can be switched to one grade.
With reference to Figure 12, give the procedure chart of eight fast double-clutch speed changer downshifts in the embodiment of the present invention.In Figure 12,1 ~ 8 is expressed as gear value.
In Figure 12, such as, current gear is eight grades, needs gear to be down to one grade.According to sequential downshift method, then gear change process is eight grades → seven grades → six grades → five grades → fourth gear → third gear → second gear → mono-grade.And adopting jump type to downshift, then the change procedure of gear can be eight grades → seven grades → fourth gear → mono-grade, thus visible, can realize being down to one grade from eight grades by three gear change.The gear change process of being down to one grade from eight grades also can be eight grades → seven grades → six grades → five grades → fourth gear → mono-grade.
Gear is changed to one grade from seven grades, and in sequential downshift method, gear change process can be seven grades → six grades → five grades → fourth gear → third gear → second gear → mono-grade.In jump type downshift method, the change procedure of gear can be seven grades → fourth gear → mono-grade, also can be seven grades → six grades → five grades → fourth gear → mono-grade, can also be seven grades → fourth gear → third gear → second gear → mono-grade.
The gear change process that other gears are down to one grade from current gear with reference to the downshift procedure chart Figure 12, can not done herein and repeats one by one.
As can be seen here, gear is down to fourth gear from seven grades only needs a downshift operation to realize, clutch only needs to carry out once mutual, and do not need to be down to six grades, six grades through seven grades and be down to three gear change that five grades, five grades are down to fourth gear, clutch needs to carry out three times alternately, and synchronizer carries out three pre-hungs operation.Same, gear is down to one grade from fourth gear also only needs a downshift operation to realize, clutch only needs to carry out once mutual, and do not need to be down to third gear through fourth gear, third gear is down to second gear, second gear is down to three gear change of a grade, clutch needs to carry out three times alternately, and synchronizer carries out three pre-hungs operation.While quickening downshift operation, decrease the frequent operation to clutch and synchronizer, the working life of clutch and synchronizer can be increased.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
