CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202421002054 filed on 11/01/2024, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
Generally, the present disclosure relates to a vehicle assembly. Particularly, the present disclosure relates to handlebar assembly mounting assembly for saddle type vehicles.
BACKGROUND
An efficient and safe handlebar mounting arrangement ensures the rider's control and stability while operating a saddle-type vehicle. The handlebar serves as the primary interface between the rider and the vehicle, allowing for efficient steering, balance, and manoeuvrability. Therefore, a well-designed handlebar mounting arrangement is required to securely fasten the handlebars to a vehicle frame and allow fine adjustments to optimize the rider’s posture, comfort, and control.
Conventionally, the primary components of the handlebar mounting arrangement of a saddle-type vehicle comprise a handlebar assembly, a steering plate, a head tube, bearings, a preload nut, an adjuster nut, and a lock nut. The handlebar assembly consists of a handlebar, designed for ergonomic grip, connected to the vehicle’s steering plate. A steering column passing through the head tube of the vehicle forms an integral part of the vehicle steering mechanism. Further, the preload nut, adjuster nut, and lock nut tightly hold the handlebar assembly in place via the locking mechanism. Specifically, the preload nut is threaded onto the steering column to compress the bearings eliminating any misalignment between the head tube and the steering plate. Furthermore, the adjuster nut allows for adjustments of the bearings and ensures smooth, friction-free movement of the steering components. Subsequently, the lock nut is tightened to secure the adjuster and preload nuts in place, preventing the preload nut from loosening during the vehicle operation.
However, there are certain problems associated with the existing or above-mentioned arrangement for the mounting of the handlebar on the saddle type vehicle. For instance, the stability of the preload nut and the adjuster nuts depends solely on the lock nut. The loosening of the lock nut due to frequent vibrations, allows the preload nut and adjuster nuts to loosen, resulting in steering instability or unsafe riding experience. Additionally, the improper setting of the adjuster nut leads to excessive tension (resulting in stiff handling) or reduced tension (leading to loose handling). Furthermore, the above-mentioned arrangement requires frequent maintenance or re-adjustment based on the rider shifting or changes in the steering requirements during use.
Therefore, there exists a need for a mechanism for the mounting of the handlebar on the saddle type vehicle that is stable, safe, and overcomes one or more problems as mentioned above.
