Description
Technical field
The present invention relates to automotive transmission technology, more particularly to a kind of pair clutch three-speed gear.
Background technology
The driving cycle of automobile is complicated and changeable, and running resistance and travel speed change greatly, the clothes when straight road surface is at the uniform velocity advanced
Rolling resistance and frontal resistance are smaller, and grade resistance or acceleration resistance in climb very steep slopes or anxious acceleration are very big, required
Driving force has several times of even more than ten times of gaps, in addition, automobile should to meet special road section even more slow with several kms of speed per hour
Speed is slowly creeped again can be with the even faster speed fast running of speed per hour km more than 100, it is necessary to driving wheel is quite wide in range
The interval operation of rotating speed, and the gasoline engine or diesel engine for being widely used as automobile engine all cannot directly provide such wide in range torsion
Square and rotating speed between engine and driving wheel, it is necessary to seal in automotive transmission extension moment of torsion and rotating speed with multiple speed reducing ratio
The scope power demand changeable to meet Automobile Complex.Automobile dynamic quality and fuel-economy performance are constantly carried to meet user
Requirement high, the gear number of automotive transmission is on the increase, but more gear numbers to cause that automotive transmission has more complicated
Structure, manufacture maintenance cost it is higher.
Single reduction gear more than current electric automobile using only one of which gear ratio is driven, and this is difficult to meet Automobile Complex
Changeable power demand, otherwise climbing capacity is poor, it is slow to raise speed, or even if motor rotating speed is very high, it is impossible to well
Take into account driving force and speed.If electric automobile can not only be obviously improved electronic vapour using the speed changer with multiple gear ratio
The power performance of car, moreover it is possible to reduce to motor, control system, power battery pack requirement, so as to reduce electric automobile
Dynamical system cost.The further efficiency collection of illustrative plates research to motor understands, if electric automobile is using with more gears
The speed changer of number, with the power demand of automobile closer to matching, there is motor output higher to imitate for the moment of torsion and rotating speed of motor
Rate, this is also very meaningful to saving electric energy, extension distance travelled.
Although many gear automotive transmissions matched with gasoline engine or diesel engine technology maturation and have been widely used, its tool
There are the defects such as complex structure, volume are big, weight is big, manufacturing cost is high, and motor has more excellent than gasoline engine and diesel engine
Elegant moment of torsion and rotating speed output characteristics, electric automobile are inappropriate using many gear automotive transmissions of traditional vapour.
Patent document CN101380768A discloses a kind of two-speed automatic transmission for electric vehicle, including input shaft,
Output shaft, clutch, brake, epicyclic gear train and differential mechanism, input shaft are coupled with sun gear, and brake can be by gear ring

Open, motion and moment of torsion by input shaft by sun gear input planet gear arrange slow down after again by planet carrier output can obtain one compared with
The low or first gear of big gear ratio；Operational brake discharges gear ring, and closure clutch makes sun gear and gear ring be bound up, moves
Being exported by planet carrier again after input shaft is arranged by sun gear and gear ring input planet gear with moment of torsion can obtain a direct high.
The speed changer is skillfully constructed, and can obtain the bottom gear and a direct high for smaller gear ratio of larger gear ratio, improves
The power performance of electric automobile, but the shifting of transmission speed discrepancy is too big, and shift quality, and only two speed changes are influenceed unavoidably
The electric automobile gear device of ratio can't well meet the changeable power demand of Automobile Complex.
Booming electric automobile market needs to be adapted to many speed transmissions of electric automobile, and research and development are adapted to many of electric automobile
Speed transmission accords with the demands of the market.
