Description

High-speed labor-saving bicycle

The technical field is as follows:

the invention relates to a bicycle, in particular to a high-speed labor-saving bicycle.

Background art:

the traditional bicycle uses a chain wheel chain to transmit power, the number of teeth of a large chain wheel and a small chain wheel is about 2: 1, so that the large wheel rotates for one circle and the small wheel rotates for two circles, namely the large wheel rotates for one circle when being stepped on by feet. In order to increase the running speed, the tooth number of the large chain wheel must be increased, the tooth number is increased, the diameter of the chain wheel needs to be enlarged, the diameter is enlarged, the crank needs to be increased, and otherwise, labor is wasted because the wheel shaft cannot be used. However, the crank is increased, and the foot of a person cannot be increased, so that the existing mechanism can hardly increase the speed of the bicycle. For a long time, people thought various methods for increasing the speed, but the methods are not ideal, have the effects of reducing friction force, reducing air resistance, changing speed by using gears, and reducing the weight of the car body by using manufacturing materials, and the like, although the methods have certain effects, the manufacturing cost is high, and the methods are difficult to accept by the general public.

Along with economic development, the living standard of people is improved, and people seek more and more to be fast and comfortable for traveling traffic, so that the existing oil-burning automobile motorcycles and the electric automobile motorcycles are full of cities and countrysides, which causes parking difficulty and traffic jam, so that the urban streets and the countryside roads are widened and widened, and nonrenewable land resources are occupied. The main appliances of bicycles for past trips are few, if the speed of the bicycles can be improved by one time or more, the bicycle is not used with much effort or more labor, people may use the bicycles again when going on a short trip, thus the traffic pressure can be relieved, the environmental pollution can be reduced, and the resources are saved.

The invention content is as follows:

the invention aims to provide a high-speed labor-saving bicycle which not only needs to improve the running speed, but also needs less force and even saves more labor. To achieve the purpose, the invention is realized by the following technical scheme.

The high-speed labour-saving bicycle is formed from frame, front and rear wheels, saddle, driving handlebar, pedal, foot cover, supporting rod, connecting rod, driving gear, driven gear and straight-tooth flywheel.

The frame is different from the existing bicycle in that the rear section of a space for mounting a rear wheel below the frame is widened so as to mount a gear. Two supporting rods are arranged in addition, the upper head of the supporting rod is fixed on the rear clothes rack, and the lower head of the supporting rod is connected with a wheel shaft; the front and rear wheels, the saddle and the steering handle are still used without modification, but the rear wheel hub is lengthened; the pedal rod is a long rod which is slightly bent, one end of the pedal rod is connected with the supporting rod, the other end of the pedal rod is fixed with a short shaft installation pedal, and a connecting rod is installed in the middle of the pedal rod; the pedal and the foot sleeve are still used, the arc-shaped foot sleeve is fixed on the pedal, the pedal is similar to a horse pedal for riding a horse after being combined with the foot sleeve, and the foot sleeve can also be used on other bicycles; the driving gear is a straight gear (or a helical gear), an eccentric shaft mounting connecting rod is fixed at the edge, and a central shaft is fixed on the frame; the driven gear is an integral gear formed by overlapping two gears with a big gear and a small gear, the small gear is arranged in front of the driven gear, the big gear is arranged behind the driven gear, the small gear is meshed with the driving gear, and the shaft is fixed on the frame; the straight-tooth flywheel is formed by changing the conventional sprocket flywheel into a straight-tooth flywheel, and is still arranged on the wheel hub and meshed with the large gear of the driven gear.

The invention is newly provided with two pedal rods, two supporting rods, two connecting rods, two foot sleeves, two driving gears, two driven gears and two straight-tooth flywheels. The two groups are distributed into two groups, one group is arranged on the left side of the vehicle, and the other group is arranged on the right side of the vehicle. When the eccentric shaft on the left driving gear is installed, if the eccentric shaft is arranged at the lower part, the right eccentric shaft is arranged at the upper part.

When the high-speed labor-saving bicycle is used, the foot does not need to step on the pedal to do 360-degree circular motion as the traditional one, but does 40-degree reciprocating circular motion, so that the injury to the knee can be reduced. Compared with the traditional bicycle, the bicycle of the invention has the advantages that the rotating speed of the wheels is improved by more than 150 percent, and the labor is saved by more than 50 percent on the contrary because of the adoption of the power transmission mode of the lever (pedal lever) and the wheel shaft (driving gear) and the multi-stage gear speed change. Moreover, a labor-saving wheel shaft is used, and if the arm-waiting wheel shaft or the labor-saving wheel shaft is used, the labor is saved and the speed is higher. And the pedal is provided with the foot sleeve, so that power is applied to the wheels when the foot is stepped down and then ascended, and the foot is not ascended. The foot can apply force intermittently if the vehicle is going to run at a low speed. It is a traffic tool with no pollution, energy saving and low cost. The invention can also be used for traffic equipment such as a single manpower tricycle and a plurality of manpower quadricycles.

Description of the drawings:

FIG. 1 is a schematic view of the construction of the present invention.

The specific implementation mode is as follows:

the present invention will be further explained with reference to the drawings.

As shown in figure 1, the high-speed labor-saving bicycle is characterized in that the rear section of a space between rear wheels arranged below a frame 1 of the conventional bicycle is widened, a driving gear 2 and a driven gear 3 are arranged, and the driving gear 2 is meshed with a pinion in front of the driven gear 3 (a dotted small circle indicates that the pinion is arranged in front of the dotted small circle). The shafts of the

gears

2 and 3 are fixed on the rear section below the frame 1, the front end of the shaft of the gear 2 cannot extend out of the gear surface and is level with the gear surface, otherwise, the movement of the connecting rod is blocked; the straight-tooth flywheel 4 is still fixed on the rear wheel hub, so that the teeth are meshed with the large gear of the driven gear 3; a round hole is arranged at a proper position in the middle of the supporting rod 5 to connect the pedal rod, the upper end of the handle rod is fixed on the rear clothes rack, and the lower end is connected with the wheel axle; a long through groove is formed in the middle of the pedal rod 6 at a proper position for installing a connecting rod, a through hole is formed in the side face of the through groove for making a pin hole, a round hole is formed in one end of the pedal rod and connected with the supporting rod 5, a pin is tied on the round hole, and a pedal shaft 7 is fixed at the other end of the pedal rod; the upper end of the connecting rod 8 is connected with the pedal rod 6 and is pinned with an upper pin, the lower end is connected with an eccentric shaft in front of the

driving gear

2, and 9 is an eccentric shaft mounting position; the pedal 10 is fitted over the pedal shaft 7, and then the foot cover 11 is fixed to the pedal.
