Description
Technical field
Adaptively increase square automatically with split type the present invention relates to driving device for electric vehicle field, more particularly to a kind of electric car
Save the split multidisc clutch assembly of drive assembly.
Background technology
At present, automobile, motorcycle, electric bicycle are essentially all directly to control section by speed adjusting lever or accelerator pedal
Valve or current control speed, or speed change is realized using hand-control mechanical automatic automatic transmission mode.The behaviour of handle or accelerator pedal
The operation of human pilot is depended entirely on, operation and garage's situation mismatch can be usually caused, cause motor operation unstable,
There is stall phenomenon.Motor vehicle by rider in the case where being unaware of running resistance, according only to experiential operating control change
, there is problems with unavoidably in speed variator：1st, motor speed is forced due to running resistance increase in startup, upward slope and heavy load
Decline in the work of inefficient area.2nd, because no mechanical transmission adjusts moment of torsion and speed, it can only be promoted the use of in plains region,
It can not meet and be used under mountain area, hills and heavy load conditions, reduce and use scope.3rd, installing space is small at driving wheel, installs
It is difficult to accommodate automatic transmission and other new technologies again after engine or motor.4th, do not possess adaptive function, it is impossible to from
Dynamic detection, amendment and the operating mistake for excluding driver.5th, when speed change is unexpected, power of motor is necessarily caused to be hindered with traveling
Power is difficult to match.6th, it is poor apart from short, climbing capacity to continue, and accommodation is small.
Spirally bored as Chinese Patent Application No. 201510565642.0 discloses a kind of battery-operated motor cycle inner rotor motor
Set transmission self-adapting automatic gear shift drive assembly, it include internal rotor motor, casing, power transmission shaft, slowly keep off transmission mechanism and
Mechanical intelligent adaptive rate assembly, slow gear transmission mechanism is coated at a driving sleeve and inner ring including freewheel clutch inner ring
Inner circle be provided be used for driving sleeve coordinate spiral cam.There is following defect in the patent：
1st, the rubbing surface in the patent uses taper transferring structure, and friction area is limited, and faying face is poor, and is difficult to,
Increase torsional forces by increase disc spring quantity, torque value in 70-80N.m, with reference to when axial compressive force in more than 15000N, and from
Axial compressive force after the separation of clutch assembly reaches as high as 25000N, and the diameter of axle only has 20mm main shaft in prolonged high pressure stress
Under, axially all related bearings can not be born, and easily cause main shaft bending, and moment of torsion is unstable, the mechanical switching instant of driving climbing
There is impact phenomenon, mechanical performance is unstable, the defect such as market maintenance rate height, it is impossible to produce in batches.
2nd, the kind of drive of original main shaft and external conical sleeve is to use lead of screw groove in the patent, and centre storage is a diameter of
6mm steel ball is come what is realized, and reference for assembling is poor, and main shaft and external conical sleeve lead of screw groove processing are extremely complex so that the system of product
Cause high.In addition above-mentioned patent complicated in mechanical structure, product parts are more, poor practicability.
3rd, power transmission shaft is directly driven by slowspeed machine, motor cost is big, and moment of torsion is small, and electric current is big, and big electricity is also easy to produce during climbing
Stream, have impact on the traveling distance that storage battery once charges, shortens the service life of storage battery.
4th, battery-operated motor cycle electromechanical, vehicle is single, and operation strategies are small.
