3. PREAMBLE OF THE DESCRIPTION

The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[0001] The present invention generally relates to the field of automotive engineering and pertains specifically to a steering assembly for a vehicle. It particularly focuses on enhancing the security and stability of a vehicle's steering column through an innovative steering limiter.
BACKGROUND
[0002] Steering systems in vehicles, particularly two-wheeled vehicles such as motorcycles and bicycles, are critical for ensuring safe and precise control. The steering mechanism typically consists of a steering column, a steering shaft, and various associated components, such as locking members and bearings, which facilitate smooth rotation and prevent unwanted movement. However, over time, traditional steering assemblies have faced challenges related to maintaining the stability of the steering mechanism, particularly during the assembly process and under the forces experienced during vehicle operation.
[0003] A key issue with conventional steering assemblies is the potential for improper alignment or insufficient locking of components, which can lead to instability in the steering system, compromised safety, and difficulty during assembly. Specifically, the connection between the steering shaft and the locking members, such as the lower bearing lock nut, must be secure and precise to prevent slippage or misalignment, which may result in malfunction or failure of the steering system.
[0004] Additionally, the process of installing and tightening the locking members may exert significant force on the components, risking damage to the assembly or incomplete fastening, especially if the components are not properly aligned. Existing solutions typically rely on basic washers or simple teeth mechanisms to connect components, but these methods may not always ensure a secure or durable fitment, leading to potential issues with performance and longevity.
[0005] Thus, there exists a need for an improved steering assembly that enhances the ease of installation, ensures precise alignment, and prevents damage due to excessive force during assembly. It also needs to provide a more secure and durable connection between the various components, particularly the steering shaft, the locking members, and the steering limiter, to ensure the safety, reliability, and long-term performance of the vehicle's steering system.
[0006] In an example, an Indian patent application IN201641002088A provides a steering assembly for a two-wheeled vehicle, the steering assembly comprising a steering shaft, a steering arrestor assembly including a top steering arrestor and a bottom steering arrestor,wherein the top steering arrestor and the bottom steering arrestor are interlocked to each other by a locking member disposed there between, the locking member includes a first set of projections capable of being seated in one or more first provisions disposed on the bottom steering arrestor and a second set of projections capable of being seated in one or more second provisions disposed on the top steering arrestor and wherein, at least one of the first set of projections and the second set of projections includes two or more projections comprising a first projection and a second projection disposed adjacently to each other and separated by a pre-determined angle.
[0007] However, the locking arrangement on the above-mentioned application is distributed to both arrestors which provides a scope for better load transfer reduction.
[0008] The present invention addresses these challenges by introducing a steering assembly that incorporates an innovative steering limiter (arrester) that further includes a dual set of teeth (a first and a second set of teeth) for precise alignment and quick, secure fitment, along with load-bearing components such as washers to ensure even load distribution during the tightening process. These features work together to provide a more stable, durable, and user-friendly solution for vehicle steering assemblies.
