The technical solution of the utility model is, a kind of electro-tricycle speed-changing mechanism, comprise can with the DC machine of vehicle frame fixed connection, with DC machine bonded assembly main shaft, be installed in the drive sprocket on the main shaft, can be fixed on driven sprocket on the rear axle and the chain equipped with drive sprocket and driven sprocket, and said main shaft by left side bearing and right side bearing can with the vehicle frame fixed connection, its innovative point is:
Also comprise second drive sprocket, can be fixedly mounted on second driven sprocket on the rear axle, with second drive sprocket and the second equipped chain of second driven sprocket, on the left and right sides wall, be respectively equipped with at least 2 along same radius circumferencial direction well-distributed inserting column be provided with along the circumferential direction the variable block dish of the groove of arranging, and by pulling out the speed change manipulation assembly that head, the connecting lever that can be dynamically connected with drive control lever and locations are formed;
The interlude of main shaft is provided with outer spline section;
The variable block dish is provided with internal splined hole, and the outer spline section bearing fit of splined hole and main shaft;
In the interior sidewall surface of the drive sprocket and second drive sprocket, be respectively equipped with can with the spliced eye of the set inserting column bearing fit of variable block dish;
The drive sprocket and second drive sprocket, kink is on the reduced diameter section of main spindle multiple spline section both sides respectively;
Speed change is handled pulling out in the groove that head is located at the variable block dish and being bearing fit of assembly, and the fulcrum hole of connecting lever can be dynamically connected by bearing pin and vehicle frame;
On the spline segment of main shaft, be provided with the location pit; Speed change is handled the flexible location pellet shot from a slingshot of the locations of assembly, can match with pit;
Can understand that by the above technical scheme that provides the utility model has been owing to installed the relatively simple speed-changing mechanism of a kind of structure additional, thereby realize the purpose of this utility model.What should be noted that the utility model provides is a kind of speed-changing mechanism with two retaining speed changing functions.If on this basis, adopt identical therewith technical scheme, make three retainings or the above speed-changing mechanism of three retainings, yes better.
Under operating condition, chaufeur is pulled joystick, make speed change handle assembly and slide to the left or to the right, can make respectively in the set spliced eye of the set inserting column insertion drive sprocket of variable block dish or second drive sprocket, can realize the variable-speed operation of electro-tricycle by variable block rim main spindle multiple spline section.
For the actual use of electro-tricycle operating condition and the consideration of safe in operation, further innovative point of the present utility model also is, also comprises overriding clutch; Overriding clutch is connected with main shaft with the DC machine output shaft respectively.Owing to the existence of overriding clutch, both can realize the idling work of motor; Avoid the work of motor interruption, save starting current consumption, can also when electro-tricycle starts, play buffer protection function sprocket wheel, chain.
After technique scheme was implemented, what the utility model had was simple in structure, and preparation cost is low with respect to gear transmission, and manoeuvrable is reliable, but realized the characteristics of chain gear electro-tricycle variable block speed governing, was conspicuous.
