High efficient district makes electric vehicle motor under full working scope that can be operated in 95% high efficient district；With respect to single speed retarder, using two level
Speed change is with the obvious advantage, such as motor performance is required to weaken, Motor torque is only the 58% of level-one speed changer, CO2 emissions
7% is reduced, course continuation mileage about promotes 8%；And for the multi-shifting speed variator that general-utility car uses, in electric vehicle using upper, by
In the big characteristic of motor instantaneous torque, development cost can be increased and increase occupancy volume by increasing excessive gear, lose motor
The advantages of instantaneous torque is big.In addition, currently employed transmission gear group need to be equipped with taper roll bearing to eliminate axial force.
For power motor under electric vehicle full working scope is made to keep high efficiency, solve transmission gear group axial force it is excessive and
The problems such as volume is larger and for increase electric vehicle course continuation mileage, the present invention use double helical spurgear and gear train space cloth
Office's structure, having many advantages, such as to transmit power height, smooth running, low noise, axial force can offset and compact-sized, for expansion
Electric automobile gear device form, promotes electric vehicle to adapt to complex road condition etc. with practical application valency at electric vehicle climbing capacity of strengthening
Value.

It counts out a kind of electric vehicle two being made of double helical spurgear and keeps off speed change gear, can effectively expand existing electric automobile gear device knot
Configuration formula.
The present invention adopts the following technical scheme that achieve the above object：
A kind of electric vehicle two being made of double helical spurgear keeps off speed change gear, including motor in electric automobile, gear set, from
Clutch group, power input shaft, a gear jackshaft, two gear jackshafts, output shaft and the differential mechanism with main deceleration；Wherein described gear
Group includes herringbone driving gear, herringbone one keeps off left gear, herringbone two keeps off left gear, herringbone one keeps off right gear, herringbone
Shape two keeps off right gear and herringbone driven gear, and the gear in the gear set uses double helical spurgear；The clutch
Group includes a gear clutch, two gear clutches；The motor in electric automobile is connected firmly with the input shaft, the input shaft and herringbone
Shape driving gear connects firmly, the herringbone one keeps off left gear and the herringbone two keep off left gear with the herringbone driving tooth
Wheel engagement, the gear jackshaft connect firmly the herringbone one and keep off left gear, and the herringbone one keeps off right gear and herringbone two
Gear right gear is engaged with the herringbone driven gear, and the two gears jackshaft connects firmly the herringbone two and keeps off left gear.
A kind of electric vehicle two being made of double helical spurgear of the present invention keeps off speed change gear, and feature also resides in：The people
Font driving gear, the herringbone one keep off left gear, the herringbone two is kept off left gear and is laid out for longitudinal space, central point
Triangular shape；Meanwhile the herringbone driven gear, the herringbone one gear right gear, the herringbone two keep off right gear
Also it is laid out for longitudinal space, central point triangular shape.
Compared with the prior art, the present invention has the beneficial effect that：
1st, the present invention has transmission power height, smooth running, low noise, axial force can using double helical spurgear structure
The advantages that counteracting；And using double helical spurgear as transmission gear structure type, because it has the advantages that axial force can be offset,
Therefore deep groove ball bearing can be used in the bearing of speed change gear, and speed change gear cost is reduced with this.
2nd, the present invention is driven using the double helical spurgear of space layout, and each center transmission shaft point is made to be had a generally triangular shape in side
Shape is conducive to reduce speed changer vertical structure arrangement space, therefore can realize more compact space layout, and it is electronic to have
Automobile saves the advantages of space.
