Description

M286179 IV. Creation Instructions (1) [Technical Fields of the New Type] This creation is about the driving chain of a dilapidated car. 'Specially refers to the wheel used for self-assembly at both ends i = system: metal-wrapped with body-shaped body ^, joint and tread joint, and then a complex person; bf · Μ layer covering its outer edge The crank of the furnace, w, * s, = shell and then reinvented. The demand for materials can be withstood at the same time to reduce the rigidity of the material, and to lighten the pedaling force of the father and the father. [Before the technology is self-traveled by tradition; due to the self-representation of new people, self-collection, shock absorbers, and words, and rear wheels; Lai* to drive the ride of 6 forces by the rear of the curved flywheel with the crank This technique] has not been used for rushing, and the appearance of functional vehicles such as use and leisure has become more and more, including the frame, with the transmission system, the flywheel, the axle and the force exerted on the pedal, and one turn to the rear flywheel. The purpose of the guide; therefore, it must, in the high-strength car f over two hundred years of research and development, not only the ΐϊ tool extended to the competition, sports and fitness booking car in Europe and America is quite popular, especially the mountaineering style plus Equipped with an ever-evolving bicycle collection. The composition of the car can be generally divided into six systems: steering, transmission, shifting, braking, etc. The system includes pedals, cranks, chain plates, chains, and in the case of cranks, the rider is the straightest. The main components. The pedaling force is transmitted by pedaling the pedal handle to the toothed piece, and then the force is transmitted by the chain to move the drum, the wire and the rim to advance, mainly by the rotation method as the strength requirement of the power transmission. The industry's design of the crank is more focused on strength.

(S M286179, creation instructions (2) Degree impact $ safety will not have breaks and bends under riding; light weight, the lighter the bicycle, the better, so the more labor-saving ride, the more flexible, shock-absorbing In order to reduce the impact force; in general, the commonly used crank material is aluminum 0 gold, carbon fiber, titanium alloy and alloy steel, which is also a crank material that meets the above requirements. [New content] W (Technical problem to be solved) Since the two ends of the crank are connected to the pedal and the gear plate respectively, it must have high strength and hardness. The industry uses metal materials to facilitate the processing of the composite material with light weight on the handle. Covering; the crank is also divided into two types: according to the left and right sides of the gear plate, there are claws or not; according to the 'know crank structure', please refer to the ninth figure, which mainly has a first The handle body (80) and the second handle body (82) are combined with a hollow tubular body (84). The first and second handle bodies (80) (82) are made of metal. One end of the first handle body (800) and the second handle body (8 2 One end is coupled to the inside of the hollow body (8 4 ), and the tube body (8 4 ) is a material of the composite material: thereby the first handle body (8 〇) and the second handle body (8) 2) and the pipe body (8 4) three / Kyrgyzstan as a whole crank, and its function to reduce weight. Only 'the structure is the first and second handle of the metal material (8 〇) ( 8 2) The part is connected with each of the pedals and the gear plate to form a predetermined thickness-degree to facilitate processing into a joint and drilling a thread, etc., so that the two ends still have a considerable weight, so that the weight is reduced. The effect is not obvious. Another conventional structure, please refer to the tenth figure, which mainly includes a song

Page 6 M286179 IV. Creation Description (3) ^ The handle body (90) is provided with a first joint block (92) and a second joint block (9 4), characterized in that the crank body (90) a core portion (9 1 ) of a carbon fiber material is coated on both ends of the anger portion (9 1 ) to respectively bond the first and second bonding blocks (9 2 ) (9 4 ), and the core portion (9 1 ) One end extends and forms a carbon fiber claw on the outside. So the structure is constructed, but the claw is easy to ride on the road surface. If it is subjected to the impact structure on the ground below, it still has the carbon fiber material. Compared with the carbon fiber, the self-riding force of the carbon fiber is the same as the strength of the handle structure layer (9 6 ), and the above-mentioned conventional knot material of the whole bicycle causes the above-mentioned pedaling force to be insufficient and reduced. It also has a crank extending from one end of the outer structure. The structure has vibration under the structural strength, and the reason; therefore, the weight of the weight of the case and the lightweight design are greatly reduced, and the vibration of the part is generated from the creators, so the above improvement is improved (solved) The technical means of the problem is the Liuwen bicycle crank structure of Daru's work. The thin-body metal formed by the carbon fiber with iron core disclosed in this creation contains a metal body, which is an integrated 7-two combination. a first joint portion and a first member respectively having a predetermined joint shape and a predetermined geometric shape; a first combined outer edge for fastening the hollow portion of the joint portion The predetermined geometric shape of the matching portion has a first joint portion with the second knot; a second joint member is fixedly disposed at a predetermined geometric outer edge of the ' & j hollow; °"joint; with the above components, with a complex

$ 7 M286179 IV. Creation Instructions (4) The material layer is designed to be stacked with the outer edge of the second joint to achieve weight reduction, and because of the stage of the bicycle industry's invitation, it is only good, so that the improvement can be achieved. Covering each of the metal body and the first portion to form a complete bicycle crank increases the crank strength. The technological developments in the field of cranks have been able to make a better change in a small part of the technical features, which is a patentable creation. (Compared with prior art) The main purpose of this creation

Supporting the white Ο I ^ driving crank structure, the ^ is to provide a carbon fiber with a core to fight the strength, can withstand the gentleman, the use of metal thin core structure to enhance the second vibration of the creation Impact and pedaling force.
