Description
Technical field
The utility model is related to a kind of double-clutch automatic gearbox, more particularly to a kind of electric car is automatic with the double clutches of 4 gears
Speed changer.
Background technology
Pure electric automobile has the advantages that small noise, zero-emission, easily operated and safeguard, is passed because effect on environment is relative
Uniting, automobile is smaller, and its prospect is had an optimistic view of extensively.
Because the motor of pure electric automobile has good governor control characteristics, therefore, pure electric vehicle power in industry
Using single shift transmission or two shift transmissions more than transmission system, still, for that torque demand is larger and rotating speed is relatively low to be electronic
Che Shi, such as, for load-carrying in the passenger car or load-carrying vehicle more than 14t, using single shift transmission, will be unable to carry while meeting
Have there is climbable gradient not more than 14t electric bus (or electronic logistic car) in lotus ability and maximum speed, at present, domestic main flow
Sufficient the problem of (climbable gradient<20%).Using two shift transmission structures, then a gear speed is than too big, so that a gear state is most
It is too low at high speed (often<30Kph)；And two gears are to meet maximum speed lifting, often using overgear (i.e. monodentate wheel set
Speed ratio<1).So make it that adjacent gear speed difference is excessive, if needing necessarily to climb when running into normally travel region (speed 20-60kph)
Slope, then unable to do what one wishes in the presence of two gears, a gear speed does not reach, the technical problem that two gear torques do not reach.
Solve problem from actual bearer ability angle, heavily loaded car is more than 10m, load-carrying 14-18t, such as using 3 gears it is double from
Close, then on the one hand speed is too bigger than span, require higher for motor performance, the 80-100kw rated motors of current market main flow are difficult
To solve, the maximum speed that high pulling torque can be transmitted is too low (1 gear high pulling torque climbing is difficult to more than 30kph), so in the urgent need to setting
Meter is a kind of to solve big load, the automatic transmission of even more high load-carrying vehicle (tractor, interval lorry etc.).
