Semiaxis.The 3rd gear 13 and the engaged transmission ratio of the 4th gear 14 are set as i2, the 5th gear 15 and the engaged transmission of the 6th gear 16
Than being i3, then when second clutch 42 is engaged, engaged transmission ratio is i2 × i3 in automatic transmission 10, and this is the second operating mode.
Because the second power source is auxiliary power source, and motor can be any speed governing, in the first operating mode or
If the second power source starts simultaneously under second operating mode, engaged transmission ratio remains in that the above results in automatic transmission 10.
The 7th gear 17, the 3rd gear 13 (now according to idle pulley from the point of view of), the engaged transmission ratio of the 4th gear 14 are set as i4,
When first clutch 41 and second clutch 42 disconnect, engaged transmission ratio is i4 × i3 in automatic transmission 10, and this is the 3rd
Operating mode.
Wherein, the big I of gearratio i1, i2, i3 and i4 is changed by changing the size or the number of teeth of gear, so as to change
Become the gearratio of automatic transmission 10.
From the foregoing, the drive assembly of the utility model embodiment can realize three kinds of gearratios：
First power source starts, and first clutch 41 is engaged, and when second clutch 42 disconnects, is engaged in automatic transmission 10
Gearratio is i1 × i3.Now, the second power source can start or close.When second power source starts, drive assembly can be increased
Total driving force, in vehicle start, can make vehicle shorten accelerator, faster realize run at high speed.
First power source starts, and second clutch 42 is engaged, and when first clutch 41 disconnects, is engaged in automatic transmission 10
Gearratio is i2 × i3.Now, the second power source can start or close.Equally, when the second power source starts, driving can be increased
Total driving force of assembly.
Second power source starts, and first clutch 41 disconnects, and when second clutch 42 disconnects, is engaged in automatic transmission 10
Gearratio is i4 × i3.Now, the first power source can start or close.When first power source starts, the first power source it is dynamic
Power cannot be transferred to axle half shafts, and only ISG motors play a part of generator, renewable generating, electric power store into battery or
Person uses for the operating of the second power source.
From the foregoing, the vehicle traction assembly can realize dual power source input, three kinds of speed than transmission, type of belt drive spirit
It is living, meet traveling demand of the vehicle to different road conditions, when vehicle is when climbing is born a heavy burden, more double dynamical input, large speed ratio may be selected
Transmission, improves vehicle driving force, makes up vehicle and drives hypodynamic defect；When vehicle is in cruising condition, single-power may be selected
Input, smaller speed are run at high speed requirements than transmission with meeting vehicle, energy saving, raising vehicle course continuation mileage.
