Abstract
The utility model relates to a double-chain transmission device for a two-wheeled motorcycle, wherein two driving chain wheels are coaxially disposed on an output shaft of an engine, two driven chain wheels are coaxially disposed on a hub of a driven wheel, and the two driving chain wheels and the two driven chain wheels are transmitted via two chains. The two chains can be two separate single chains or a chain formed by connecting two single chains into a whole. By using two driving chain wheels, two driven chain wheels and two chains to drive, the utility model can avoid the phenomena of gear blocking and chain drop-off and can prolong the service life of chain and chain wheel. Furthermore, the utility model has simple structure and decreases accident and maintenance.
Description
Technical field
The utility model relates to a kind of motor bike driving device, refers to the double-stranded bar driving device of a kind of two-wheeled motor vehicle especially.
Background technology
At present, adopt the transmission of strand bar between the drive sprocket of two-wheeled motorcycle and the driven sprocket mostly, this structure has the following disadvantages: the one, make the length increase of chain owing to the wearing and tearing of chain, chaufeur is swung the gap for guaranteeing that chain travels normally, need often to adjust the distance between flower wheel and the driving engine, make chain that suitable elasticity be arranged.The 2nd, the rapid wear between chain and drive sprocket and the driven sprocket needs to change sprocket wheel, causes a service expenditure to strengthen.The 3rd, cause chain to come off easily from sprocket wheel, promptly be commonly called as " chain-taking ", after chain, the sprocket wheel wearing and tearing to a certain degree, the chain amplitude that swings is bigger, loosening trace exceeds standard, and makes the chain releasing phenomenon often to occur in travelling, and the lighter brings the trouble of interrupting travelling, keeping in repair adjustment to chaufeur.When serious, the chain that comes off meeting latch, the unexpected locking of wheel in causing travelling causes safety misadventure.
In the practice, have the part two-wheeled motorcycle to adopt the way of installation chain tensioning device to regulate the degree of tension of chain, but it does not have guide function, can not well solve the latch problem that produces because of chain swinging yet.
Use the chain guides in addition, adjusting device for chains waits and overcomes above-mentioned deficiency, but has complex structure, defectives such as installation and maintenance inconvenience.
The utility model content
The purpose of this utility model provides a kind of service life that increases chain and sprocket wheel, and the teeter amplitude that reduces chain is avoided the double-stranded bar driving device of two-wheeled motor vehicle of latch and chain releasing.
For achieving the above object, the technical solution adopted in the utility model is: the double-stranded bar driving device of a kind of two-wheeled motor vehicle, comprise driving engine, flower wheel wheel hub, coaxially on the output shaft of described driving engine be provided with 2 drive sprockets, coaxially on the described flower wheel wheel hub be provided with 2 driven sprockets, between 2 drive sprockets and 2 driven sprockets by double-stranded bar transmission.2 drive sprockets, 2 driven sprockets can the integral production moulding, also can install by split production.
The double-stranded bar driving device of above-mentioned two-wheeled motor vehicle, double-stranded bar can be the strand bar of 2 separation, also 2 strand bars can be connected as a single entity.
The beneficial effects of the utility model are:
Adopt double-stranded bar transmission, reduced the pressure that travels of strand bar, significantly reduced the wearing and tearing of chain and sprocket wheel.Thereby increased the service life of chain and sprocket wheel.
Because the width of double-stranded bar doubles than strand bar, reduced the teeter amplitude of chain, even under the situation that chain becomes flexible, chain also is not easy to come off from flower wheel, solved the problem of " chain-taking ", increase the safety of travelling, reduced maintenance, avoided the accident that causes because of the chain latch.
The utility model has been avoided latch, chain releasing phenomenon by adopting 2 drive sprockets, driven sprocket and double-stranded bar transmissions, has increased the service life of chain and sprocket wheel.Simple in structure, minimizing accident and maintenance.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Description of drawings
Fig. 1 is that the utility model master looks scheme drawing
Mark among the figure: 1-driving engine 2-output shaft 3-drive sprocket 4-driven sprocket 5-flower wheel wheel hub 6-chain
The specific embodiment
As shown in Figure 1, the double-stranded bar driving device of a kind of two-wheeled motor vehicle, comprise driving engine 1, flower wheel wheel hub 5, coaxially on the output shaft 2 of described driving engine be provided with 2 drive sprockets 3, coaxial being provided with between 4,2 drive sprockets of 2 driven sprockets and 2 driven sprockets on the described flower wheel wheel hub by double-stranded bar 6 transmissions.3,2 driven sprockets 4 of 2 drive sprockets can the integral production moulding, also can install by split production.
The strand bar that double-stranded bar 6 can be 2 separation is parallel to be installed, and also can 2 strand bars be connected as a single entity by bearing pin.
In travelling, because the width of double-stranded bar 6 doubles than strand bar, reduced the teeter amplitude of chain, the degree of wear of chain and sprocket wheel when having reduced the strand bar has increased service life of chain and sprocket wheel.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
Claims (2)
1. the double-stranded bar driving device of a two-wheeled motor vehicle, comprise driving engine (1), flower wheel wheel hub (5), it is characterized in that: the output shaft of described driving engine (2) is gone up coaxial 2 drive sprockets (3) that are provided with, coaxial 2 driven sprockets (4) that are provided with on the described flower wheel wheel hub, between 2 drive sprockets and 2 driven sprockets by double-stranded bar (6) transmission.
