Abstract

The utility model discloses an electronic control stepless speed change belt transmission device used for a bicycle, and belongs to the technical field of designing and manufacturing of bicycles. The electronic control stepless speed change belt transmission device is characterized in that a speed change device is in the shape of a flat-head horn, the longitudinal section is in the shape of a symmetrical trapezoid, rectangular grooves parallel to inclined faces are formed in the four inclined faces in the perpendicular and horizontal directions of the horn shape, guide rails with threads are embedded in the grooves, the threads on the guide rails are meshed with gears on output shafts of direct-current motors, triangular sliders are installed on the direct-current motors, groove openings are formed in the sliders for a driving belt to be embedded in, the four groove openings of the sliders are located in the same driving plane of the driving belt, the driving belt winds through three opening faces of three sliders, and the other end of the driving belt is arranged on a driving tooth disk; a shaft is arranged in the shaft center of the speed change device in the shape of the flat-head horn is tightly fastened to an axle of a bicycle; the input ends of the four direct-current motors are connected with the output end of a message transmission device of a handle. The electronic control stepless speed change belt transmission device has the advantages that a message transmission button is arranged on the handle, forward and backward rotation of the motors can be driven as required, wheels can be driven in a stepless speed change mode, and the device is simple in structure and few in needed equipment.

Description

A kind of electron steering stepless change belt-type driving device of bicycle use

Technical field

Belonging to bicycle designs, manufacturing technology field, is exactly the designing technique to a kind of gear of bicycle use.

Background technology

The speed change of current conventional bicycle, be by changing the working in coordination of toothed disc of chain and different forward and backward size, changes speed of a motor vehicle speed.This step change has a lot of shortcomings, and also very complicated in structure, it will have the forward and backward fluted disc of the difference size much matching, and with coordinating of chain, and has the system of pulling out of finger to realize gear shift, and mechanical component are many, complex structure.

Summary of the invention

The utility model provides the electron steering stepless change belt-type driving device of a kind of bicycle use a kind of simple in structure, easy for operation.

The technical scheme that the utility model is taked is:

A kind of electron steering stepless change belt-type driving device of bicycle use, the stretching device that comprises transmission system and chain associated with it, its scheme is: transmission system is that tack is horn-like, elevation profile is symmetrical trapezoidal, on four inclined-planes of trumpet-shaped vertical and horizontal direction, the rectangular slot that has parallel-slope, in groove, setting-in threaded guide rail, screw thread on guide rail and the gear engagement being contained on DC machine shaft, triangular shape slide block is installed in DC machine, on slide block, there is notch, driving belt in embedding, the notch of four slide blocks is in and drives in the same driving plane of belt, drive belt to walk around three opening surfaces of three slide blocks, the other end is around driving on chain wheel, the horn-like transmission system Zhou of tack center has axle and bicycle shaft is fastening joins, the input end of four DC machine and the signal transmitter mouth on handle join, and have and send respectively the positive signal that makes motor forward and two buttons that make the negative signal of motor reversal on handle.

The beneficial effects of the utility model are:

The utility model is simple in structure, easy for operation; Owing to there being the button that sends respectively positive signal and negative signal on handle, send as required positive signal and negative signal, drive motor forward or reverse, thus can continuous transformation, realize stepless change and drive wheel.

Accompanying drawing explanation

Fig. 1 is the utility model transmission system elevation profile schematic diagram;

Fig. 2 is driving device perspective view.

The specific embodiment

Now the utility model is described in further detail by reference to the accompanying drawings,

A kind of electron steering stepless change belt-type driving device of bicycle use, the stretching device that comprises transmission system and chain associated with it, its structure is: transmission system 9 is that tack is horn-like, elevation profile is symmetrical trapezoidal, on four inclined-planes of trumpet-shaped vertical and horizontal direction, the rectangular slot that has parallel-slope, in groove, setting-in threaded 6 guide rail 5, screw thread on guide rail and gear 3 engagements that are contained on DC machine 2 shafts, triangular shape slide block 1 is installed in DC machine, on slide block, there is notch, driving belt 4 in embedding, the notch of four slide blocks is in and drives in the same driving plane of belt, drive belt to walk around three opening surfaces of three slide blocks, the other end is around driving on chain wheel 8, the horn-like transmission system Zhou of tack center has axle 7 to join with bicycle shaft is fastening, the input end of four DC machine and the signal transmitter mouth on handle join, and have and send respectively the positive signal that makes motor forward and two buttons that make the negative signal of motor reversal on handle.

Described guide rail, limiting stopper is all equipped with at its two ends.

Described chain wheel and notch all have and the teeth that drive belt to match.
