The course of work and principle
As shown in fig. 6, the utility model moment inspecting transmission device basic structure is 2K-H planetary transmission structures, left side is too Sun wheel is fixed by torque sensor resilient sleeve, and right side sun gear is inputs, and planet carrier is output, design parameter such as following table It is shown:
Speed reducing ratio:
As shown above, main shaft is i=0.3714 to chain wheel gearratio, and main shaft rotates 1 week chain wheel rotation 1/0.3714= 2.69 weeks, i.e. speedup exports.
As shown in figure 5, there is ratchet Retchet gear type freewheel clutch, when bicyclist is pedaled forward between main shaft and right side sun gear Main shaft drives right side sun gear to rotate forward when stepping on, and passing power, when bicyclist's backward pedal, main shaft is beaten with right side sun gear Sliding not passing power.
As shown in fig. 6, when bicyclist scrunches pedal, main shaft rotary power is input to right side planetary gear through right side sun gear, Since left side sun gear is fixed by torque sensor resilient sleeve, left and right planetary gear is integrated, and left side planetary gear is less than the right side Skidding star-wheel, planetary gear will to the right sun gear direction of rotation in the same direction revolution and rotation, due to planetary gear revolution and autobiography direction It is identical, therefore planet carrier rotating speed will be greater than the speed of mainshaft, i.e. speedup exports, and planet carrier output torque is the i of spindle force square at this time Times, i.e., 0.3714 times;Resilient sleeve Moment for spindle force square (1-i) times, i.e., 0.6286 times, main shaft torque and resilient sleeve There are linear relationship between cylinder Moment, and direction is identical.The variation relation of resilient sleeve Moment and bicyclist The variation relation for trampling torque be it is identical, using the moment variations signal on resilient sleeve be supplied to controller as with bicyclist The corresponding input signal of torque is trampled, bicyclist can be accurately measured and trample torque, the rapid shape of riding for understanding bicyclist State and intention, can be well matched with power-assisted power, realize optimal power-assisted effect.
As shown in fig. 7, driving velocity sensor magnet ring synchronous rotary when main shaft rotates, leant out on the left of torque signals converter Two velocity sensor Halls face magnet ring, and two Halls export orthogonal signalling, surveyed according to the pace of change of Hall orthogonal signalling Determine the speed of mainshaft and direction of rotation.
When bicyclist's power-assisted is ridden, manpower drives bicycle jointly with motor power, that is, has manpower and motor power two-way Power transfer path.Motor power bang path is:Rotor gear → hollow wheel gear → motor side mono-directional overrun clutch → OK Carrier → chain wheel.Manpower power transfer path:Main shaft → right side sun gear → right side planetary gear → planet carrier → chain wheel.
When simple manpower is ridden, planet carrier rotates and hollow wheel gear is static, therefore between planet carrier and hollow wheel gear Motor side mono-directional overrun clutch skids, and motor will not be driven to rotate, non-interference.
When simple electric power is ridden, planet carrier and the rotation of right side sun gear and main shaft is static, therefore right side sun gear ratchet Very heavy skidding with main shaft, will not drive main shaft to rotate, non-interference.
Bicyclist scrunches the rotating speed of pedal and is ridden at this time between 42-48 teeth in 60-70rpm, the chain wheel number of teeth under normal circumstances Scanning frequency degree disclosure satisfy that the demand of riding of most of bicyclist between 15-25Km/h.The utility model chain wheel rotating speed is main shaft 2.69 times of rotating speed, the optional 15-18 teeth of the chain wheel number of teeth, ensure identical riding speed.
Traditional built-in motor is target design decelerating through motor ratio according to chain wheel output speed 60-70rpm in design, is subtracted Speed substantially between 25-30, is generally slowed down than empirically optimum range using two-stage or three-level.As speed reducing ratio is too small, then need Motor outputting torsion is improved, can so increase motor size, is unfavorable for minimizing, opposite speed reducing ratio is excessive, then necessarily increases Big transmission system size, so can also increase motor size, be unfavorable for minimizing.Chain wheel output speed is main in the utility model 2.69 times of rotating speed, therefore motor can be reduced to the 1/2.69 of traditional optimal speed reducing ratio to the speed reducing ratio between chain wheel, i.e., 9.3-11.2, above-mentioned speed reducing ratio scope can realize with primary speed-down, 7 tooth of the rotor number of teeth, hollow wheel gear in the utility model 74 tooth of the number of teeth, speed reducing ratio 10.6, can not only make motor size accomplish optimum condition and greatly simplify motor side deceleration knot Structure, realizes the miniaturization of overall built-in motor.
The above-mentioned electric bicycle with reference to embodiment to a kind of moment inspecting transmission device and its application device The detailed description that motor carries out, is illustrative rather than limited, can include several implementations according to limited scope Example, therefore all changes and modifications without departing from the scope of the present general inventive concept, should belong within the scope of protection of the utility model.
