Description

Multifunctional force saving bicycle

The utility model belongs to the bicycle designs field, particularly a kind of structure design of multifunctional force saving bicycle.

Present bicycle both domestic and external is not all installed the labour saving machine that the people relatively adapts to, major cause is that bicycle power produces power by lever principle, before normally two throw of levers being fixed in the middle of the hinge wheel with axle, the pedal that utilization the is contained in the top moving power that converts to that tramps with one's feet, because the radius of preceding sprocket wheel is equivalent to be contained in 2/3rds of sprocket wheel upper lever arm degree, it is conspicuous can not changing out bigger power; In addition, the too thin and poor durability of the transmission system structure of variable-ratio bicycle, its reason is that to be contained on the trailing wheel a plurality of sprocket pieces too thin and the thin force resistance of the transmission design structure sprocket piece lower end is low, owing to often promote chain speed change on sprocket piece, be subjected to its retaining power and inevitably collision in the process of moving, make change-speed box easily deformable, be that speed change is inaccurate, very not as satisfactory, and change-speed box is stirred by trailing wheel rung bar in the process of moving ruin, cause traffic accident and economic loss.Though change-speed box has reduced the speed of a motor vehicle, economized power, cause personnel to aggravate exercise intensity, make that personnel's fatigue is dog-tired by bike.Electronic at present, morpet is owing to be contained in storage battery electric energy reserves harshness on the vehicle frame, and it is too low and stroke distances short and frequent charge to cause bearing load, makes troubles and the economic loss of power consumption to the people.

Based on the above defective, present bicycle running relies on the inertia height, causes can't reach on smooth road surface and runs at high speed, and the utmost point does not meet people's adaptation load; Owing to do not possess hill climbing ability, therefore can not fully use bicycle at the existing bicycle in most of mountain area, generally form a kind of descending by bike, hard case of upward slope go-cart.

The purpose of this utility model is for overcoming the weak point of prior art, develop a kind of bicycle that has the labour saving machine device, be installed on the cycle frame, has speed change accurately, arbitrarily, people's foot steps on quick rapidly, bicycle is gained in weight little, step on gently under steam and bicycle is entered rapidly run at high speed, on the road surface, mountain area, can make the bicycle hill climbing ability reach the effect of motor bike climbing, and in climbing is advanced, can stop existing bicycle because of the little parking phenomenon of conversion power.

A kind of multifunctional force saving bicycle of the utility model design-calculated, by the reinforced vehicle frame, the multi-purpose car handle, front and back wheel, the bumper of front and back wheel, assembly pulley, change speed gear box, maneuver box, driving box, vertical leg is stepped on device, and the car shell assembles, and it is characterized in that, said reinforced vehicle frame, be welded into preceding spider by direction cover, upper beam, cant beam, seat post, below this cant beam, be fixed with load frame and rear wheel frame, be fixed with the Vee formation frame in preceding spider rear end and carry the thing frame on the back; Said multi-purpose car handle, be arranged on the direction set upper side of vehicle frame, the upper end of said front-wheel bumper is installed in direction cover lower end, and its lower end and front-wheel wheel shaft are fixed together, the upper end of rear wheel shock-absorbing device is installed in the lower end of Vee formation frame, and its lower end and rear wheel frame are fixed together; Said assembly pulley is installed on the upper beam, said change speed gear box is installed on the load frame, said maneuver box is installed in load frame front end, and link to each other with change speed gear box, said driving box is installed in the middle of rear wheel frame and the trailing wheel, and link to each other with change speed gear box, said vertical leg is stepped on device and is linked to each other with assembly pulley, and said car shell is fixed on the vehicle frame both sides.
