Abstract
The utility model relates to a driving-wheel device for motors, which comprises a wheel hub casing, a wheel hub cover, a wire motor, a clutch and a speed reduction mechanism, wherein, the speed reduction mechanism is a secondary planetary gear train; the clutch is an overrunning clutch; the input sun wheel of a first planetary gear train of the speed reduction mechanism is fixed on a motor rotor; the input planetary wheel frame of the first planetary gear train is integrated with the output sun wheel of the secondary planetary gear train; the central wheels of inner teeth of the two planetary gear trains are integrated; the central wheels are fixed on a motor casing; the output planetary wheel frame of the secondary planetary gear train is also the claw wheel of a clutch. The utility model has the advantages of compact structure, reasonable layout, stable motion, low noise and low cost. The utility model is especially suitable for being used as the electric wheel hub of a front wheel and a rear wheel for power-assisted bicycles.
Description
The utility model relates to electric drive, particularly a kind of drive of motor wheel apparatus of travelling by driven by power on the moped of being used for.
Existing electric assisted bicycle motor decelerating mechanism generally adopts the gear train of beam type common involute cylinder tooth or helical teeth, and because of its bearing capacity is low, noise was big when gear carried out high speed rotating, and structure is not compact, so result of use is not ideal enough.
The purpose of this utility model is at existing electric assisted bicycle above shortcomings, and a kind of rational in infrastructure, compact in design, drive of motor wheel apparatus that noise is little are provided.
The utility model is realized by following manner:
A kind of drive of motor wheel apparatus comprises hub shell, wheel hub cover, motor, clutch and reducing gear, and wherein reducing gear is made up of the secondary planet train, and clutch is a freewheel clutch; The input sun gear of the first order planet circular system of reducing gear is fixed on the rotor, the input star wheel frame of first order planet circular system and the output sun gear of second level planet circular system are connected as a single entity, the central wheel of internal teeth of gear for two stage planetary gear train is connected as a single entity, and be fixed on the motor case, the output star wheel frame of second level planet circular system is again the ratchet wheel of clutch.
Advantage of the present utility model is: made full use of the incorporate advantage of planet circular system central axis, compact conformation; Each planetary gear be evenly distributed on sun gear around, rationally all carry, increase the stationarity of running; Noise and cost have been reduced in addition.
The utility model is particularly suitable as a kind of electric wheel hub that bicycle front-wheel or trailing wheel travel by driven by power that is installed on.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is the structural representation of present embodiment, and wherein (1) represents hub spindle, (2) expression input sun gear, (3) expression rotor, (4) expression line of input star-wheel, (5) expression motor case, (6) expression hub shell, (7) expression central wheel of internal teeth, (8) expression wheel hub cover, (9) expression sleeve, (10) expression roller, (11) expression spring, (12) expression output star wheel frame, (13) expression output planetary wheel, (14) expression input star wheel frame, (15) expression output sun gear.
Present embodiment is an electric assisted bicycle front-wheel electric wheel hub, around hub spindle (1) rotation, comprises hub shell (6), wheel hub cover (8), motor, clutch and reducing gear.Wherein reducing gear is the secondary planet train, first order planet circular system is made up of input sun gear (2), line of input star-wheel (4), central wheel of internal teeth (7) and input star wheel frame (14), and second level planet circular system then is made up of output sun gear (15), output planetary wheel (13), central wheel of internal teeth (7) and output star wheel frame (12); The central wheel of internal teeth of gear for two stage planetary gear train (7) is designed to one, and is fixed on the motor case (5); The output sun gear (15) of second level planet circular system is embedded on the input star wheel frame (14) of first order planet circular system, and both are an integral body; Sleeve (9), roller (10), spring (11) and constituted freewheel clutch as the output star wheel frame (12) of ratchet wheel.Because the input sun gear (2) of first order planet circular system is fixed on the rotor (3), power is imported from it, slows down through planet circular system, by output star wheel frame (12) output, by the effect of clutch, drive the wheel hub cover (8) link to each other with sleeve (9), finally drive whole wheel hub.
Claims (2)
1, a kind of drive of motor wheel apparatus comprises hub shell (6), wheel hub cover (8), motor, clutch and reducing gear, and it is characterized in that: reducing gear is made up of the secondary planet train, and clutch is a freewheel clutch.
2, drive of motor wheel apparatus according to claim 1, it is characterized in that: the input sun gear (2) of the first order planet circular system of reducing gear is fixed on the rotor (3), the input star wheel frame (14) of first order planet circular system is connected as a single entity with the output sun gear (15) of second level planet circular system, the central wheel of internal teeth of gear for two stage planetary gear train (7) is connected as a single entity, and be fixed on the motor case (5), the output star wheel frame (12) of second level planet circular system is again the ratchet wheel of clutch.
