Abstract
The utility model relates to an electric bicycle drive mechanism, which belongs to the technical field of bicycles, and comprises a frame which is formed by connecting a front beam, a saddle tube, a rear upper fork, a rear lower fork; a big tooth disc is arranged under the frame; the utility model is characterized in that the electrical motor is arranged at the position below the rear fork and at the back of the big-teeth disc; a tension wheel is arranged at the rear side of the motor, the tension wheel rotates with the bottom of protective support, the upper end of the protective support rotates with the guide wheel , the centerlines of the big tooth disc, the electrical gear, the guide wheel, the rear sprocket wheel are in the same plane, and driven by a chain in order. The utility model has the advantages of the innovative design, simple structure, less manpower consumption, reliable performance and multi-level speed changing, practicality and high versatility, low production cost and convenience for installation and maintenance.
Description
Technical field
The utility model belongs to technical field of bicycles, is specially the Electrical Bicycle transmission device.
Background technology
Existing Electrical Bicycle adopts rear-wheel hub formula motor to realize electric servodrive mostly, and this driving device is because motor-field power and rear-wheel weight are ridden the power increasing when causing manpower to be ridden, and there do not have ordinary bicycle to ride to be light.The mid-driving device of employing is also arranged, and is that motor is placed the large fluted disc inboard, adopts the secondary type of drive, its complex structure, manufacturing cost height, installation, maintenance inconvenience.Also having a kind of structure, is that motor is placed the large fluted disc inboard, drives the inboard coaxial minor sprocket of large fluted disc by chain, and large fluted disc rotates, and directly drives rear wheel by chain again, realizes the single speed transmission, and its shortcoming is not to be suitable for how fast vehicle.
The utility model content
The utility model is at the above-mentioned problems in the prior art, and design provides a kind of technical scheme of simple in structure, Electrical Bicycle transmission device that productive costs is low, can realize multi-change speed, and manpower is ridden laborsaving.
Described Electrical Bicycle transmission device, comprise the vehicle frame that connects and composes by front-axle beam, saddle pipe, Seat stay, Chain stay, large fluted disc is installed in the vehicle frame bottom, it is characterized in that motor is installed in the rear of Chain stay below, large fluted disc, the motor rear portion is provided with tension wheel, and tension wheel and the lower end normal-running fit that protects support protect support upper end and track adjusting wheel normal-running fit, the line of centers of large fluted disc, motor gear, track adjusting wheel, tension wheel, back sprocket wheel cooperates by chain transmission successively at grade.
Above-mentioned Electrical Bicycle transmission device is skillfully constructed, and is simple in structure, and it is laborsaving to ride, dependable performance, and can realize multi-change speed, and practicality and highly versatile, productive costs is low, and installation, maintenance is convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in the figure, the vehicle frame that front-axle beam 12, saddle pipe 11, Seat stay l0, Chain stay 8 connect and compose, large fluted disc 1 is installed in the vehicle frame bottom, motor 2 is installed in the below of Chain stay 8, the rear of large fluted disc 1, motor 2 rear portions are provided with tension wheel 5, and tension wheel 5 and the lower end normal-running fit that protects support 4 protect support 4 upper ends and track adjusting wheel 9 normal-running fiies, the line of centers of large fluted disc 1, motor gear 3, track adjusting wheel 9, tension wheel 5, back sprocket wheel 7 cooperates by chain 6 transmission successively at grade.Track adjusting wheel 9, motor gear 3 form rational cornerite with chain 6, tension wheel 5 is the center with track adjusting wheel 9, but arc rotates under the torque spring effect of track adjusting wheel 9, to realize the purpose of auto-tensioning, and, can realize multi-change speed by regulating the position of tension wheel 5.Free-wheel clutch is set respectively on the main shaft of motor 2, large fluted disc 1, and automatic clutch switches in the time of can realizing that manpower and electric power-assisted are by bike, and making rides becomes more laborsaving, and its concrete connection structure does not repeat them here for existing known technology.
