Chain for vehicle

Abstract

The invention discloses a chain for a vehicle, belonging to driving parts of non-motor vehicles. The chain comprises a chain link body, a roller with a shaft hole, and a hinged shaft, wherein each chain link body is provided with a pair of chain pieces and at least one tongue-shaped closing plate, one ends of the pair of chain pieces are respectively formed into a small linked crushing plate, and the other ends are respectively formed into a large linked crushing plate, the pair of small linked crushing plates are respectively provided with small crushing plate hinged holes, the pair of large linked crushing plates are respectively provided with large crushing plate hinged holes, and the small linked crushing plates extend into the large linked crushing plates of the adjacent chain link body; the roller with a shaft hole is arranged between the pair of the small linked crushing plates; the hinged shaft penetrates into the large crushing plate hinged holes, the small crushing plate hinged holes and the shaft hole to hinge the small linked crushing plate of one chain pieces of the chain link body with the large linked crushing plate of the other chain pieces of the chain link body; and the tongue-shaped closing plate is formed on the large linked crushing plates. The whole strength of the chain is improved; the tongue-shaped closing plate not only plays roles of dust blocking and draining, but also further improves the strength of the chain link body so that the service life of the chain is prolonged.

Description

technical field [0001] The invention belongs to the technical field of transmission components of non-motor vehicles, and in particular relates to a chain for vehicles. Background technique [0002] As is well known to the public, the chain structures used by non-motor vehicles such as bicycles, battery electric mopeds, variable speed bicycles, racing cars, performance cars (acrobatic cars), pedal tricycles, baby carriages and even vehicles for the disabled are basically the same. , and, because bicycles have a long history, the chains on the aforementioned vehicles and even motor vehicles such as motorcycles (including two-wheeled and three-wheeled motorcycles) and transmission chains on industrial equipment are all inherited from bicycle chains. structure. [0003] For a long time, more specifically in the past hundred years, the reason why people have not been able to make substantial changes to the chain structure of the aforementioned vehicle is that the structural for...

Problems solved by technology

CN2123652U discloses a bicycle chain (applied by the same applicant as CN2113379U). The upper edge of the central part of the chain piece is formed into a straight shape, while the lower edge forms a concave portion, which improves the shifting action, but this scheme will affect the strength of the chain piece

[0005] Although the above-listed but not limited to the patented technical solutions of the vehicle chains listed have corresponding technical effects, the applicant believes that there are the following disadvantages: First, because they do not get rid of the closed connection between the adjacent chain link bodies. The second is that the overall strength of the chain cannot be guaranteed, especially the aforementioned CN2123652U and CN201258947Y, due to the need to make a concave portion to the chain sheet and to open a hole in the middle of the waist, etc., so the original strength is fragile The chain piece is undoubtedly worse, although it can show the expected technical effect, but there is a problem of losing sight of the other; the third is that the upper and lower parts of the chain structure including the above-mentioned patents and the chain structure seen in the current market are open in use. That is, they are all open, and dust, rain or similar sundries can easily invade the chain; Fourth, although the chain mentioned in the aforementioned patent does not specify whether it is an even number or an odd number after cutting, as far as the applicant knows, The number of links of the known vehicle chains in use is either an even number or an odd number, and the odd and even numbers cannot be selected, which causes inconvenience to practical applications.
