Abstract
Description
- The present invention relates to linkage mechanism for vehicle, in particular to a linkage mechanism for combining two wheels for identical motion of sway.
- Conventional motor vehicles such as motorcycles usually run on two wheels aligned on the same line for good mobility. However, normal single front wheel or single rear wheel is not stable under some circumstance and also not safe or suitable for the elder, unskilled, or handicapped.
- Instead of single wheel for the front or rear wheel, a combination of two wheels can be used to highly improve the stability of the movement and operation of the vehicle. To maintain the stability and the mobility as well, the two combined wheels must be linked together for identical motion of tilt or sway. Therefore, to create a linkage mechanism capable of linking two wheels for identical motion of sway through a simple assembly with dust and rain proof is an urgent objective to achieve.
- Accordingly, the primary object of the present invention is to provide a linkage mechanism to combine wheels of vehicle for identical motion of sway. Through the assembly, two wheels can be linked for providing better stability and mobility to vehicle. The simple assembly can also sustain the force of sway and protect most of the components from dust and moisture so as to prolong the lifetime of the assembly.
- To achieve the above object, the present invention includes a linking block for receiving a center axle. A sway block is pivoted to the center axle, and a connecting rod is pivoted to the sway block. A main frame serves to retain two ends of the center axle. Two sway rods are pivoted to two ends of the main frame and the two ends of the connecting rod. Two wheels are arranged to the two sway rods so as to sway simultaneously and identically through the linking of the connecting rod.
- In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
- Referring to
FIGS. 1 to 3 , a preferable embodiment of a linkage mechanism for double-wheel combination of vehicle according to the present invention is illustrated. The linkage mechanism includes amain frame 10, linkingblock 11,center axle 12, connectingrod 13, and twosway rods - The
center axle 12 is arranged to the linkingblock 11. Asway block 121 is pivoted to thecenter axle 11. Thesway block 121 has two coaxial throughholes 121A. - The connecting
rod 13 has a throughhole 130 so that the connectingrod 13 is pivoted to thesway block 121 through ashaft 120 penetrating the throughholes 121A of thesway block 121 and the throughhole 130 of the connectingrod 13. - The
main frame 10 is assembled by afront frame 14 and arear frame 15 through couplings and assemblingholes 144 of thefront frame 14 and assemblingholes 154 of therear frame 15.
