As preferably, described armature spindle is stretched out by the two ends of tube-like envelope respectively, and is respectively equipped with gear box at the two ends of armature spindle, and each gear box is respectively equipped with output shaft, on the output shaft of a described braking mechanism gear box located therein.Two ends at motor are provided with gear box respectively, then the output shaft of two gear boxes can drive two wheels simultaneously and rotates together, because two gear boxes all mesh together with the armature spindle of motor simultaneously, therefore, when the effect that is subjected to braking mechanism when the output shaft of a gear box was prevented from rotating, then the output shaft of the armature spindle of motor and another gear box also had been prevented from rotation simultaneously.
As preferably, described gear box comprises casing, case lid, countershaft built-up gear and output shaft built-up gear, and described countershaft built-up gear is located on the countershaft; Ecto-entad is provided with outside framework oil seal, ripple packing ring and ball bearing successively between described output shaft and casing, is provided with ball bearing between described casing and output shaft the inner.
As preferably, described armature spindle end is provided with gear hobbing, and armature spindle is by this gear hobbing gear hobbing part and countershaft built-up gear engaged transmission; Described countershaft is provided with the countershaft gear hobbing, and countershaft is by this countershaft gear hobbing and output shaft built-up gear engaged transmission.Adopt gear and tooth axle engaged transmission in the gear box, can reduce the volume of gear box, make that the structure of tube shaped electric machine is more compact, be convenient to more be provided with.
As preferably, described rotary pawl axially is connected the location with gearbox output shaft by fluting awl end holding screw.
As preferably, described braking mechanism is provided with the brake shell outward, and described brake shell one end and gear housing offset, and its other end and case lid offset, and described handle passes the brake shell and cooperates with braking mechanism.
Therefore, it is lower to the utlity model has cost, and braking ability is better, characteristics such as compact conformation.
