Shown in Figure 25, the reversing gear 100 of motor-tricycle and driving engine 99, shift case 103 are contained in bottom of frame, and reversing bar 34 is convenient to move with hand in the left side up, and the Shift lever 98 of engine drive mechanism is in the bottom, left side, and it is moving to be convenient to tramp with one's feet; There are handlebar 91, front-wheel 93, fuel tank 97 in the front portion, and there are railway carriage 96, trailing wheel 94,95, chain 92, back sprocket wheel 101, vehicle seat 102 in the rear portion.
Using method of the present utility model is as follows:
At first open the driving engine of motor-tricycle, make it be in quasi-operating status, its shift transmission device and reversing gear all are in preceding line position, and are dead ship condition, at this moment, the power-transfer clutch on the castellated shaft 28 29 connects with claw type gear 32, transition gear 38, output gear 40, sprocket wheel 42;
During reversing, upwards move reversing bar 34 with hand earlier, make in the groove 57 that moves ahead of locating dowel pin 79 in the positioning plate 78 on the steering unit and throw off, and then move left the reversing bar 34, locating dowel pin 79 is entered in the reversing groove 58 of positioning plate 78, because of leverage, shifting fork pin 76 in the backing maneuvers mechanism extend in the clutch slot 61 in the power-transfer clutch 29, the corresponding connection in any 3 flat holes in 6 flat holes in clutch pawl 63 on the power-transfer clutch 29 and the flat hole gear 31, power-transfer clutch 29 and claw type gear 32 are thrown off, at this moment, power-transfer clutch 29, flat hole gear 31 connects output gear 39,40, the chain 92 of sprocket wheel 42 and rear vehicle, sprocket wheel 101;
Then, open driving engine, shift transmission device and reversing gear rotate simultaneously, and motor-tricycle car load backward retreats, thereby have finished the overall process of reversing.
Stop after reversing finishes, make progress again, move reversing bar 34 to the right, make it recover forward traveling to original position.
To sum up, the backing maneuvers flow process is:
Open driving engine---dead ship condition---on forget about it the car bar---the reversing bar is removed on a left side---reversing retreats---dead ship condition---on forget about it the car bar---the reversing bar is removed on the right side---recover forward traveling.
During reversing, when moving ahead, do not handle reversing suddenly, because of inertia is big, very easily beat tooth, damage this device, treat to handle car-backing function again after car body comes to a complete stop.
