Abstract
The utility model relates to a centrifugal clutch speed-changing device for an electric car; the centrifugal clutch speed-changing device comprises a motor, a shaft sleeve, a clutch and a speed reducer; an output shaft of the motor is connected with an input shaft of the clutch; the output shaft of the clutch is connected with the input shaft of the speed reducer; the clutch is the centrifugal clutch. According to the utility model, the centrifugal clutch is arranged between the output shaft of the motor of the electric car and the input shaft of the speed reducer; when the rotation speed of the input end of the clutch is higher than that of the output end, the clutch is engaged automatically, the motor drives the speed reducer to rotate, and the speed reducer accelerates, thereby accelerating the car; and when the rotation speed of the input end of the clutch is lower than that of the output end, the clutch separates automatically, and the speed reducer slows down gradually, thereby slowing down the car.
Description
Technical field:
The utility model belongs to the electric vehicle engineering field, is specifically related to a kind of used for electric vehicle centrifugal clutch transmission system.
Background technology:
Environmental pollution, lack of energy, people explore, develop, utilize regenerative resource to drive automobile.Have now found that and develop like new-energy automobiles such as wind power automobile, magnetic motive force automobile, solar cars; But these new-energy automobile complex structures; Build is clumsy, inefficiency, and be not suitable for long-distance operation; Therefore these new-energy automobile practical uses are little, therefore fail to access large-area applying.
For solving existing environmental problem and energy problem, electronlmobil has also been promoted in people's research and development, and electronlmobil is with its zero-emission being accepted by people gradually, and; Along with the development of electric vehicle engineering, it is original can not long-distancely to use and the charging problem is resolved gradually, therefore; The user of electronlmobil is more and more, and still, the motor and the reductor of electronlmobil are through the coupler direct connection mostly at present; This connection mode, centre are not provided with buffering, during starting during big, the low speed driving of electric current electric current big; It is unable to climb, and does not add power at a high speed, and consumption of current is excessive.And the output of motor can not change moment of torsion with road condition change, causes the havoc to motor, storage battery and controller easily.Give electronlmobil development, practicality, bring great obstacle.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of used for electric vehicle centrifugal clutch transmission system; It is between the input shaft of the output shaft of the motor of electronlmobil and reductor, centrifugal clutch to be set, when the rotating speed of power-transfer clutch input end is higher than the mouth rotating speed, and the power-transfer clutch automatic engagement; The motor-driven reductor rotates, the reductor speedup, and car speed is accelerated; When the rotating speed of power-transfer clutch input end is lower than the rotating speed of mouth; Power-transfer clutch separates automatically, and reductor slows down gradually, and car speed slows down.
For solving the problems of the technologies described above, the technical scheme of the utility model is achieved in that
A kind of used for electric vehicle centrifugal clutch transmission system; Wherein: comprise motor, axle sleeve, power-transfer clutch and reductor; The output shaft of motor is connected with the input shaft of power-transfer clutch through axle sleeve, and the output shaft of power-transfer clutch is connected with the input shaft of reductor, and power-transfer clutch is a centrifugal clutch.
Further, an end of described axle sleeve is provided with the flat key groove, and its other end is provided with spline, and an end of the flat key groove of axle sleeve is connected with the output shaft of motor, and an end of the spline of axle sleeve is connected with the input shaft of power-transfer clutch, and the input shaft of power-transfer clutch is a castellated shaft.
Further, the output shaft of described power-transfer clutch is a castellated shaft, and the input shaft of reductor is provided with spline.
The beneficial effect of the utility model is:
1, the utility model is between the input shaft of the output shaft of the motor of electronlmobil and reductor, centrifugal clutch to be set, when the rotating speed of power-transfer clutch input end is higher than the mouth rotating speed, and the power-transfer clutch automatic engagement; The motor-driven reductor rotates, the reductor speedup, and car speed is accelerated; When the rotating speed of power-transfer clutch input end is lower than the rotating speed of mouth; Power-transfer clutch separates automatically, and reductor slows down gradually, and car speed slows down.
3, the utility model power-transfer clutch volume is little, and is in light weight, and efficient is high, and the life-span is long and can transmit big moment of torsion, can accomplish the transmission tasks of general-utility car change speed gear box fully, and engagement, disengaging are rapidly.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
As shown in Figure 1, a kind of used for electric vehicle centrifugal clutch transmission system comprises motor 1, axle sleeve 2, power-transfer clutch 3 and reductor 4; The output shaft of motor 1 is connected with the input shaft of power-transfer clutch 3 through axle sleeve 2, and an end of axle sleeve 2 is provided with the flat key groove, and its other end is provided with spline; One end of the flat key groove of axle sleeve 2 is connected with the output shaft of motor 1; One end of the spline of axle sleeve 2 is connected with the input shaft of power-transfer clutch 3, and the input shaft of power-transfer clutch 3 is a castellated shaft, and the output shaft of power-transfer clutch 3 is connected with the input shaft of reductor 4; The output shaft of power-transfer clutch 3 is a castellated shaft, and the input shaft of reductor 4 is provided with spline.Power-transfer clutch 3 is a centrifugal clutch.
During use, motor 1 rotates, and for reductor 4 power is provided through axle sleeve 2 and power-transfer clutch 3; When the rotating speed of power-transfer clutch 3 input ends is higher than the mouth rotating speed, when promptly motor 1 rotating speed is higher than reductor 4 rotating speeds, power-transfer clutch 3 automatic engagements; Motor 1 drive speed reducer 4 is rotated; Reductor 4 speedups, car speed are accelerated, car acceleration when this state is fit to automobile starting or in the driving process; When the rotating speed of power-transfer clutch 3 input ends was lower than the rotating speed of mouth, power-transfer clutch 3 separated automatically, and reductor 4 slows down gradually, and car speed slows down, and this state is fit in the deceleration and docking process in the vehicle traveling process.
Be noted that; The above embodiment is to the explanation of the utility model technical scheme and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art; As long as do not exceed the thinking and the scope of the utility model technical scheme, all should be included within the desired interest field of the utility model.
