Abstract
The invention relates to a stepless speed adjusting motor with dual drive. A star shape transmission comprises a sun wheel, a star wheel, a star frame and a gear circle in a same shell body; a main motor is connected with the star frame; the speed adjusting motor is connected with the sun wheel through an off-center type clutch; the sun wheel operates in the opposite direction without resistance after the main motor is electrified; no torque is output when the star frame fails to whirl, therefore, vehicle does not operate. The speed adjusting motor whirls with the main motor in the same direction when an electronic governor provides electric current for the speed adjusting motor. The centrifugal clutch rubs with a driven wheel whirling in the opposite direction by the flick of rotation rejection block of the motor to decelerate until the driven wheel whirls in the same direction. The star frame gradually accelerates along with the change of the sun wheel from the opposite direction to the positive direction. The invention realizes the target of stepless speed change.
Description
Affiliated field
The present invention relates to a kind of motor in electric automobile rotating speed cvt output device, especially dual drive stepless speed adjusting electromotor of being used for, can realize leading the driving rotating speed also can realize than 〉=1 with output speed＜1, and step-less adjustment.
Background technology
At present, known motor in electric automobile speed governing is by electronic speed regulation and have grade mechanical speed change to realize, its electron speed regulator is that the input current that changes motor is realized speed governing, its speed adjustable range is narrow, rotating speed output is linear poor, particularly more obvious when starting acceleration, development brings and has a strong impact on to ev industry.
Quicken linear problem in order to solve the motor in electric automobile speed-adjusting start, the invention provides a kind of double driving shafts input, single cvt output device, this device has not only been realized stepless speed regulation and favorable linearity, has also reduced the electron speed regulator electric current output more than 2/3rds.
The technical scheme that technical solution problem of the present invention is taked is, in same housing, forms star-like speed changer by sun gear, star-wheel, star frame, gear ring, and main motor is connected with the star frame, and buncher is connected with sun gear by centrifugal clutch; Main electrical power rear sun gear does not have resistance to do antiport, and the star frame does not rotate no torque output vehicle and do not move.When electron speed regulator makes itself and main motor do rotation in the same way for buncher provides electric current, centrifugal clutch gets rid of piece because of the rotation of motor and flicks with the driven pulley of reverse rotation and produce friction, it is slowed down until doing rotation in the same way, and the star frame is along with sun gear quickens gradually from the variation that is backwards to forward.Realize infinite variable speed purpose.
The invention has the beneficial effects as follows, reduce large power, electrically sub-element usage quantity, reduced the crystal loss, improved the reliability of control, wide adaptability, brush, brshless DC motor, asynchronous machine, the synchronous machine motor of can deciding is arranged, and motor is that optimal operational condition after startup loads and improved output torque and electric efficiency greatly.Be directly used in driving fields such as electric automobile, promotion prospect is wide.
