Description

Bicycle continuous transmission improved structure

The present invention relates to an improved structure of a bicycle continuous transmission, which specifically refers to bicycle continuity by controlling the friction of the brakes, achieving easy and labor-saving riding and continuous shifting, and replacing the chain with a transmission to improve the safety of the rider. Transmission improved structure.

However, according to the BBC Chinese website, a 12-year European study of more than 300,000 people found that the number of people who died from exercise was twice as likely to die from obesity. The researchers found that "regardless of normal weight, overweight or obesity" Among the people, those who lack exercise are prone to die early. At the same time, the biggest cause of death from lack of exercise is cardiovascular disease, and riding a bicycle is a way to compress blood flow and accelerate blood circulation by relaxing leg movements. Strengthening microvascular tissue and aerobic exercise that makes blood vessels younger, not only can improve lung capacity, strengthen the heart, but also save a lot of fuel costs, and it is environmentally friendly, so that more and more people use bicycles as a means of transportation. Tools, however, traditional bicycles, whether or not they can automatically shift speed, when the knight steps on the pedal just started, because the tire is in static contact with the floor, the friction is greater, the knight must use very much effort to drive the bicycle forward. At the time, if the rear carries people or heavy objects, the force of trampling is relatively more laborious, especially when encountering an uphill slope. As gravity and resistance increase, many riders who ride bicycles often have heavy pedals when going uphill, and they shift gears while shifting the pedals, so that chain breaks often occur, causing bicycle damage and unable to continue riding. Must take self-hands Driving uphill is not only laborious and time-consuming; at the same time, traditional bicycles drive the rear wheels with chains. Not only do the chains need to be maintained frequently, but they can maintain their ability to drive the sprocket, and the chain is lubricated with oil, which often contaminates the knight’s pants. Or the skirt, it is also prone to falling off, causing sudden stoppages, even when the hair falls off the knight's feet. At this time, the knight must take a bicycle on foot to find a repair shop, if riding on the road or crossroads At the mouth, the chain suddenly falls off and stops, which will lead to the danger of chasing the car in the rear. These lacks are not only the long-term defects that the traditional bicycle industry can't break through, but also the long-term inconvenience of each bicycle rider. Trouble; in view of this, how to overcome the above shortcomings is the technical problem and technical effect that the creator wants to solve.

In view of the above-mentioned problems of the traditional bicycles, the creators have been carefully researched, and then actively researched and developed, and created the professional experience and experience of this industry for many years, so they created the creation of this case.

The main purpose of this creation is to provide an improved structure of a bicycle continuous transmission, which uses a driving device instead of a sprocket and a chain to drive the rear wheel forward; when the knight steps on the pedal, the drive shaft is rotated, and the rotary shaft fixed on the drive shaft Relatively rotating, and controlling the friction of the brake device makes the double-row helical gear slow or not moving, so that the second alternating helical gear and the third alternating helical gear respectively pivoted at the longitudinal ends of the rotary shaft generate a revolution and rotate, after passing through The interaction causes the second alternating helical gear and the third alternating helical gear to drive the output helical gear to be fastened, and the output helical gear rotates at a speed that the second alternating helical gear and the third interactive helical gear revolve and rotate. The speed of the action, and the output helical gear drives the first output helical gear fixed at the rear end to reach the same rotational speed. At this time, the rotating first output helical gear drives the meshing gear. The first driving helical gear rotates, so that the second driving helical gear at the other end of the first driving helical gear also rotates relative to the second driving helical gear, and the second driving helical gear drives the transmission helical gear to mesh with the meshing gear to drive the rear wheel and make the bicycle Smoothly moving forward, there will be no chain falling off and the bicycle will stop, even causing the danger of chasing the rear car. At the same time, replacing the chain with the drive device can not only save the cost of the sprocket and the chain, but also save the maintenance chain frequently. The time and cost will improve the safety of the rider's ride, and will not let the knight's pants or skirts be stained, and the convenience and superiority of the continuous variable speed bicycle will be achieved, and the economic benefits will be improved.

Another main purpose of the present invention is to provide an improved structure of a bicycle continuous transmission, which utilizes the frictional force of the brake device to control the speed of the first interactive helical gear to be slow or not moving, so that the first interactive helical gear drives the double-row oblique The speed at which the gear rotates is relatively slow or does not move. At this time, since the knight steps on the pedal, the drive shaft rotates, the rotary shaft rotates, and the second interactive helical gear and the third interactive helical gear that are respectively pivoted at both ends of the rotary shaft are generated. The revolution and the rotation, through the interaction, drive the output helical gear to rotate with the meshing force. At this time, the speed of the output helical gear rotates, and the speed of the interaction between the second interactive helical gear and the third interactive helical gear revolves and rotates, thereby changing the solid The speed of the sprocket set at the rear end of the output helical gear is relatively fast, so that when the bicycle is loaded with people, heavy objects just start or ride on the slope, the knight can easily step on the pedal and easily drive the bicycle forward. It not only saves the power of stepping, but also enhances the endurance of the climbing, and the shifting is simple and fast, and it is more convenient to see the situation at the time of riding. Friction brake means of the size of the system, achieve the best results of continuous transmission, to improve the practical advantages and convenience of the bicycle, the value of industrial utilization promotion.
