See Fig. 2 A to Fig. 2 D from the shift process of N gear (neutral) to 1 gear to be described.
When vehicle launch, the first power shaft INPUT1 is attached directly to electromotor 1, thus
First input transmission gear 3 rotates with the first power shaft INPUT1.
In this state, in variator, all of engagement device and lock unit are in neutral position state,
The most whether clutch C engages, and load does not has the electromotor 1 applied to operating.
When starting to shift to 1 gear, as shown in Figure 2 A, before clutch C engages, the
One pre-engagement gear 7 is bonded to the first jackshaft by the first-the first engagement device S1-1
CNT1, and input 1 gear power shift gear and be bonded to via 1 and 3 gear lock unit S1&3
One jackshaft CNT1.
In this state, as shown in Figure 2 B, when clutch C engages, from electromotor 1
Moment of torsion also begin to by second power shaft INPUT2 transmit, therefore moment of torsion by second input
Transmitting gear 5 and the first pre-engagement gear 7 and transmit to the first jackshaft CNT1, vehicle can
By 1 gear power shift gear on the first jackshaft CNT1 and output shaft OUTPUT to 1
Gear travels.
Thereafter, as shown in Figure 2 C, the first synchromesh gear 9 engages dress via first-the second
Put S1-2 and be bonded to the first jackshaft CNT1.
That is, when vehicle 1 gear travel time, as shown in Figure 2 B, the first power shaft INPUT1 and
Second power shaft INPUT2 rotates with identical speed, and transmits gear 3 phase with the first input
The first synchromesh gear 9 engaged and be meshed with the second input transmission gear 5 first
Pre-engagement gear 7 forms identical gear ratio.
Accordingly, because the first pre-engagement gear 7 and the first synchromesh gear 9 are with the rotation synchronized
Rotary speed rotates, and the first-the second engagement device S1-2 can be bonded to the first synchro-meshing safely
Gear 9, without causing damage to the first synchromesh gear 9.
Afterwards, the first-the first engagement device S1-1 disengages from the first pre-engagement gear 7, such as figure
Shown in 2D, but even if the first pre-engagement gear 7 disengages, the first power shaft INTPUT1 is also
It is attached directly to electromotor 1, thus from the moment of torsion of electromotor via the first input transmission gear
3 and first synchromesh gear 9 and lasting transmission to output shaft OUTPUT, thus vehicle
Continuous service can be kept off 1.
Thereafter, even if clutch C release, from the moment of torsion of electromotor 1 via being directly connected
To the first power shaft INPUT1 of electromotor 1 and lasting transmission to output shaft OUTPUT,
Therefore, it is possible to maintain 1 gear.
Afterwards, see Fig. 3 A to 3D to be described to 2 shift processes kept off from 1 gear.
When starting to shift to 2 gear from 1 gear, as shown in Figure 3A, in clutch C release
In the case of, the second pre-engagement gear 11 is bonded to via the second-the first engagement device S2-1
Two jackshaft CNT2, and input 2 gear power shift gears and connect by 2 and 4 gear lock unit S2&4
It is bonded to the second jackshaft CNT2.
In this state, as shown in Figure 3 B, when clutch C engages, from electromotor 1
Moment of torsion also begin to via second power shaft INPUT2 transmission, therefore moment of torsion via second input
Transmit gear 5 and the second pre-engagement gear 11 and transmit to the second jackshaft CNT2, vehicle energy
Enough by 2 gear power shift gears on the second jackshaft CNT2 and output shaft OUTPUT to
2 gears travel.
That is, before clutch C engages, 1 gear power shift gear pair and the first synchromesh gear 9
Being bonded together, vehicle runs with 1 gear, but when clutch C engages, the first jackshaft
CNT1 rotates with the higher rotating speed of rotating speed than the first power shaft INPUT1, and speed discrepancy is 2 gears
Power shift gear to and 1 gear power shift gear between the difference of gear ratio, this speed discrepancy passes through first
One-way clutch OWC1 absorbs.
Therefore, during shifting to 2 gears, via the first one-way clutch OWC1, when
Transmitted to the first jackshaft CNT1 by the first input transmission gear 3 when vehicle travels with 1 gear
Torque-flow, by second input transmission gear 5 and smoothly change to the second jackshaft
CNT2, therefore avoids the such as gearshift ability pulled back of vehicle bad in shift process
Change.
Thereafter, as shown in Figure 3 C, the second synchromesh gear 13 engages dress via second-the second
Put S2-2 and be bonded to the second jackshaft CNT2.
That is, when vehicle 2 gear travel time, as shown in Figure 3 B, the first power shaft INPUT1 and
Second power shaft INPUT2 rotates with identical speed, and transmits gear 3 phase with the first input
The second synchromesh gear 13 engaged and be meshed with the second input transmission gear 5 second
Pre-engagement gear 11 forms identical gear ratio.
Accordingly, because the second pre-engagement gear 11 and the second synchromesh gear 13 are with synchronization
