Chain structure design invention capable of enabling bicycle to save labor and accelerate by more than 50%

Abstract

The invention relates to a chain structure design which enables a bicycle to save labor and accelerate by more than 50%. The inspiration comes from force synthesis and decomposition, a single-wheel transmission scheme of a traditional bicycle is optimized, two or more chain sets (two wheels are provided with two chain sets, and three wheels are provided with three chain sets) are used for exerting force on a front wheel and a rear wheel respectively, and two or more times of driving force of the traditional scheme can be obtained through the same leg force. According to the optimized scheme, the speed of the bicycle can be increased, labor can be saved, the more the wheels are, the more the matched chain sets are, the more labor is saved, for example, the labor is saved by 50% at most when two wheels are matched with two chain sets. Three wheels are matched with three chain groups, so that the labor is saved by 66% at most. The four wheels are matched with the four chain sets, and labor is saved by 75% at most. The five wheels are matched with the five chain sets, so that labor is saved by 80% at most, and the like, and the acceleration and labor-saving effects are achieved.

Description

Technical Field

[0001] Bicycles or other chain-type vehicles, such as trains and tanks, have optimized transmission methods, which can make them achieve faster speeds and more labor-saving riding under the drive of original power. Background Art

[0002] Traditional bicycles are not fast and effortless to use, especially when going uphill, which is time-consuming and laborious. The reason is that the driving force of traditional bicycles is often only on the rear wheel, while the front wheel has no driving force. If we also install a drive on the front wheel, the rolling friction is small and can be ignored, then we will get twice the driving force, which greatly reduces manpower consumption. Summary of the Invention

[0003] The present invention is to combine a wheel with a chain group to form a "drive", for details, please refer to Figure 1 The large gear in the chain connects to the pedal bearing, and the small gear connects to the wheel's center axis. When the pedals are engaged, assuming the leg force remains constant, one "drive" produces 1x the driving force (assuming 1x the driving force is a traditional bicycle with a single chain). Two "drives" produce 2x the driving force, three "drives" produce 3x the driving force, and so on. Accordingly, to achieve 2x the driving force, the leg force used is halved, saving 50%; to achieve 3x the driving force, the leg force used is 1 / 3, saving 66%; to achieve 4x the driving force, the leg force used is 1 / 4, saving 75%; to achieve 5x the driving force, the leg force used is 1 / 5, saving 80%; to achieve 6x the driving force, the leg force used is 1 / 6, saving 83%; to achieve 7x the driving force, the leg force used is 1 / 7, saving 85.7%, and so on. BRIEF DESCRIPTION OF THE DRAWINGS

[0004] Figure 1 This is a simple diagram of the present invention, which describes the combination of chain groups and wheels. One combination is a "drive", and the drives are connected by pedal bearings to obtain the original power. Figure 1 The numbers represent 1: Front wheel 2: Rear wheel chain set 3: Pedal bearing 4: Rear wheel 5: Front wheel chain set If we look at the chain that rotates with the gear near the pedal bearing, we'll see that for every pedal rotation, with a traditional single chainset, the chain travels the same length as the circumference of the large gear. However, with a double chainset, the total chain travels twice the circumference of the large gear. This is why riding the same distance with multiple chainsets saves effort and is faster. Specific implementation methods

[0005] like Figure 1 As shown, Figure 1 The display shows a combination of two chain assemblies and two wheels. With three wheels, a tricycle or a bicycle with a small gap between the rear wheels can be made. Similarly, four or five wheels can be made into various shapes. However, please note that each wheel is equipped with one chain assembly, and each assembly must be controlled separately. No overlapping or connecting rods can be added.

Claims

1. The present invention is not only applicable to bicycles and tricycles, but also to other chain-type vehicles, such as trains, tanks, excavators, etc.

2. The present invention comprises a large gear and a small gear and a chain connecting them to form a chain group. The small gear is connected to the central axis of the wheel, and the large gear is connected to the pedal (power source). Together, they constitute a "drive" of "one wheel plus one chain group". The combination of multiple "drives" is the structural design of the present invention.

3. Variations of the "drive" design of the present invention are also within the scope of protection, such as an excavator using a single power source with multiple wheels, a train with multiple groups of wheels and chains, etc.
