Abstract
The utility model relates to a vehicle power device. The centrifugal foil type electric wheel driver of the utility model is composed of a printed winding DC electric machine 1, a second-stage gear speed reducer, and a centrifugal clutch 7. The hollow axle 3 with a gear of the printed winding DC electric machine 1 is sheathed on an axle 2, the hollow axle 3 is engaged with a big gear 11 of a first-stage gear speed reducer by an axle gear 12, the big gear 11 of the first-stage gear speed reducer is connected with the small gear 9 of the second-stage gear speed reducer by a gear axle 10 fixed on the back cover 18 and a fixed plate 17 of the DC electric machine, the centrifugal clutch 7 is arranged on an inner gear ring 8, a centrifugal pin 6 on the centrifugal clutch 7 is connected with a drum 5, and the drum is connected with a wheel by a spoke 19.
Description
The utility model relates to a kind of vehicle power device.
Chinese patent 922384665 discloses a kind of " eccentric wheel drive device ", comprise motor, reduction gear apparatus and power-transfer clutch, motor is a printed circuit motor, attach together together with retarder, motor is difficult for installing like this, debugging and maintenance, motor also is difficult to sealing in addition, and its retarder uses three differential teeth planetary retarders, this retarder processing, setting accuracy requires very high, corresponding tooling cost is also high, its power-transfer clutch adopts to surmount and closes device, and this power-transfer clutch is as long as motor connects with load once moving, therefore, motor can not starting under no load, cause the electric motor starting electric current very big, it is unfavorable that motor is used, and this device fuses owing to armature sheet and retarder, can't add lubricating oil, therefore, the retarder noise is big, and is easy to wear.
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provide a kind of axial dimension little, simple electric drive wheel actuator is installed.
Centrifugal foil-shaped electric wheel actuator described in the utility model is made up of printed circuit DC motor, secondary gear reducer and centrifugal clutch, the hollow shaft sleeve of printed circuit DC motor band gear is on axletree, and the big gear wheel interlock by shaft gear and first order gear reducer, the miniature gears of the big gear wheel of first order gear reducer and second stage gear reducer is connected with gear wheel shaft on the adapter plate by being fixed on the DC machine bonnet, centrifugal clutch is contained on the internally toothed annulus, centrifugal lock on it is connected with Decorative drum, and Decorative drum connects with wheel by spoke again.
Actuator described in the utility model is owing to adopt common spur wheel, than adopting planet wheel decelerator processing and installation easily, and axial dimension is shorter, can be installed on vehicle front-wheel or the trailing wheel, owing to adopt centrifugal clutch, when not reaching certain rotating speed when electric motor starting, motor and load break away from, can make the empty load of motor starting, reduced the starting current of motor, in the utility model, DC machine and retarder are separable, therefore the random apply lubrication oil of retarder, lubricating oil also is unlikely and enters motor internal generation short circuit.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 leaves constitution diagram for centrifugal clutch among Fig. 1.
Fig. 3 is the conjuncted constitution diagram of centrifugal clutch among Fig. 1.
The utility model adopts existing printed circuit DC motor 1, and the hollow shaft 3 of use band gear, can intactly printed circuit DC motor be inserted on the axletree 2 of bicycle or three-wheel vehicle like this, be convenient to motor seal, debugging and installation, when the hollow shaft 3 of band gear rotates, shaft gear 12 drives big gear wheel 11 rotations, this slows down for the first order, during big gear wheel 11 rotations, with its also together rotation of miniature gears 9 with gear wheel shaft 10, drive internally toothed annulus 8 rotations, this slows down for the second stage, and gear wheel shaft 10 is a support with motor bonnet 18 and adapter plate 17, when internally toothed annulus 8 rotates and reaches certain rotating speed, be contained in centrifugal lock 6 on the centrifugal clutch 7 that is connected with internally toothed annulus 8 under action of centrifugal force, overcome spring tension, insert in the fixed block 20 that is contained on the Decorative drum 5, promptly from evolution shown in Figure 2 to position shown in Figure 3, drive Decorative drum 5 and rotate together, and Decorative drum 5 is to be associated in wheel by spoke 19, thereby realized driven by power.When motor 1 outage stall, shaft gear 12, big gear wheel 11, miniature gears 9, internally toothed annulus 8 all stop operating, centnifugal force on the internally toothed annulus 8 disappears, centrifugal lock 6 is withdrawn under the effect of spring 21, internally toothed annulus 8 and Decorative drum 5 are broken away from, and wheel stops operating, at this moment, Decorative drum 5 can freely rotate under the transmission of manpower, can not be associated in together with retarder, motor and strengthens the resistance that uses manpower.Actuator of the present utility model was realized with connecting by ball 4 of vehicle.
Internally toothed annulus described in the utility model 8 is not fixed on the gear wheel shaft for the internally toothed annulus that floats, but with the Decorative drum bearing fit.
Actuator axial dimension described in the utility model little (being no more than 70mm), so can be contained in arbitrarily on vehicle front-wheel or the trailing wheel, when being contained in trailing wheel, increase bearing 13, bearing seat 14, foot-operated sprocket wheel 15, hitch 16 get final product.
Claims (2)
1, a kind of centrifugal foil-shaped electric wheel actuator, it is characterized in that by printed circuit DC motor 1, secondary gear reducer and centrifugal clutch 7 are formed, the hollow shaft 3 of printed circuit DC motor 1 band gear is enclosed within on axletree 2, and by big gear wheel 11 interlocks of shaft gear 12 with first order gear reducer, the big gear wheel 11 of first order gear reducer and the miniature gears 9 of second stage gear reducer are connected with gear wheel shaft 10 on the adapter plate 17 by being fixed on DC machine bonnet 18, centrifugal clutch 7 is contained on the internally toothed annulus 8, centrifugal lock 6 on it is connected with Decorative drum 5, and Decorative drum connects with wheel by spoke 19 again.
2,, it is characterized in that described internally toothed annulus 8 is the internally toothed annulus that floats by the described centrifugal foil-shaped electric wheel actuator of claim 1.
