Specification

DESC:Technical Field of the invention

The present invention generally relates to the field of Automotive Engineering. More particularly, it focuses on enhancing vehicle stability and maneuverability through a Tilting Wheel System (TWS) with stability control.

Background of the invention

In the realm of automotive engineering, two critical aspects that define the safety and performance of a vehicle are its stability and maneuverability. Stability refers to the vehicle's ability to maintain its intended path without undue deviation, particularly in adverse conditions. Maneuverability, on the other hand, is the ability of a vehicle to change its direction of motion efficiently and predictably, allowing the driver to navigate through traffic, avoid obstacles, and perform necessary movements during driving.

The conventional approach to vehicle stability and maneuverability has largely revolved around suspension design. Traditional suspension systems, including both independent and dependent setups, are engineered to absorb shocks from the road and maintain tire contact, thereby ensuring ride comfort and stability. While these systems have been effective to a certain extent, they inherently possess limitations, especially under dynamic and high-performance driving scenarios.

One of the primary limitations of traditional suspension systems is their compromise between ride comfort and handling. Systems that are too soft can lead to excessive body roll and reduced stability during cornering, while overly stiff setups can compromise ride comfort and lead to reduced traction by not allowing the wheels to adapt to road irregularities efficiently.

Dynamic driving conditions, such as high-speed cornering, sudden evasive maneuvers, and rapid acceleration or deceleration, pose significant challenges to traditional automotive design paradigms. In these scenarios, the physics of vehicular motion bring to light the inherent trade-offs in conventional suspension and steering designs. For instance, during high-speed cornering, the lateral forces exerted on the vehicle can lead to significant body roll, reducing the contact patch of the tires and, consequently, the grip, which can lead to understeer or oversteer conditions.

Moreover, vehicles with high centers of gravity, such as SUVs and trucks, are particularly prone to rollover accidents during sharp turns or sudden changes in direction. This risk is exacerbated by the limitations of traditional suspension systems in managing the complex interplay of forces acting on the vehicle during such maneuvers.

In response to these challenges, the automotive industry has witnessed significant technological advancements aimed at enhancing vehicle stability and maneuverability.

One of the major breakthroughs in this area has been the introduction and widespread adoption of Electronic Stability Control (ESC) systems. ESC systems use a combination of sensors and microcontrollers to detect and mitigate loss of traction, thereby preventing skidding and loss of control. While ESC systems have significantly improved vehicle safety, they are inherently reactive and primarily focus on correcting driver errors or compensating for limitations in the vehicle's mechanical design.

Active suspension systems represent another leap forward, offering real-time adjustment of the suspension settings based on driving conditions. These systems can mitigate body roll, improve grip, and enhance comfort by actively controlling the force applied to each wheel. However, active suspensions are complex, expensive, and often add significant weight to the vehicle, which can impact efficiency and performance. Despite these advancements, the quest for the optimal balance between stability, maneuverability, and comfort continues. The limitations of existing systems under extreme or unconventional driving conditions highlight the need for innovative approaches that can adapt to the dynamic nature of vehicular motion and the diverse scenarios encountered on modern roadways.

In this context, the concept of a Tilting Wheel System (TWS) emerges as a groundbreaking approach. Unlike traditional systems that focus on modifying or enhancing existing suspension and steering mechanisms, TWS introduces a fundamentally different paradigm by allowing controlled tilting of the vehicle's body in response to dynamic forces.

The Tilting Wheel System aims to address the core challenges in vehicle stability and maneuverability by introducing a mechanism that allows the vehicle to lean into turns, much like a motorcyclist or a bicyclist would. This leaning action counteracts the lateral forces that induce body roll, thereby maintaining a larger tire contact patch with the road and enhancing grip.

Moreover, by actively controlling the tilt angle in response to speed, steering input, and lateral acceleration, TWS can provide a more intuitive and responsive driving experience, significantly improving maneuverability, especially in tight corners and during evasive maneuvers.

Beyond performance and handling, the Tilting Wheel System also presents opportunities to enhance passenger comfort and safety. By minimizing body roll and the associated lateral forces experienced by the occupants, TWS can make high-speed cornering and dynamic maneuvers less unsettling, thereby enhancing the overall driving experience.
Additionally, the controlled tilting mechanism can be designed to adapt to varying road conditions, absorbing road irregularities and dampening vibrations, which contributes to a smoother ride.

The limitations of traditional suspension systems, the evolving landscape of automotive technologies, and the ever-increasing demands for safer, more efficient, and more enjoyable driving experiences have paved the way for innovative solutions like TWS. By reimagining the way vehicles interact with the forces of motion, the Tilting Wheel System stands as a testament to the ingenuity and forward-thinking approach required to advance automotive engineering into the future.

Brief Summary of the invention

The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements of the invention or delineate the scope of the invention. Its sole purpose is to present some concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later.

The Tilting Wheel System with Stability Control that is disclosed represents a transformative advancement in automotive engineering, aiming primarily at enhancing vehicle stability and maneuverability. This invention introduces a revolutionary approach to how vehicles handle dynamic forces, thus elevating safety and performance under various driving conditions. By implementing a system that allows controlled tilting of the vehicle’s body, akin to the movements observed in motorcyclists or bicyclists, it provides a solution that significantly improves the way vehicles respond to lateral forces during turns, effectively reducing the risk of rollovers and enhancing the overall driving experience.

The primary objective of of this invention is to improve vehicle stability, particularly during cornering and other complex maneuvers. This is achieved by enabling the vehicle’s body to tilt in response to the turn, counteracting the lateral forces that typically induce body roll, a common cause of reduced stability in conventional vehicles. By allowing for this controlled tilt, the system maintains a larger contact patch of the tires with the road surface, thereby enhancing grip and stability. This not only improves the safety of the vehicle by minimizing the likelihood of accidents associated with loss of control but also boosts driver confidence, allowing for more spirited driving in curves.

It is yet another objective of the invention is to enhance vehicle maneuverability. In crowded urban environments or during high-speed maneuvers, the ability of a vehicle to change direction swiftly and accurately is crucial.

It is yet another objective of the invention is to improves maneuverability by making the vehicle more agile and responsive to steering inputs. This is particularly advantageous in situations requiring quick directional changes or evasive maneuvers, providing drivers with the ability to navigate through traffic more effectively and safely.

It is yet another objective of the invention is to focuses on enhancing the comfort of vehicle occupants. Traditional suspension systems, while effective to some extent in absorbing road irregularities, often struggle to balance the trade-off between handling and comfort, especially in vehicles equipped with stiffer suspension 6 setups necessary for improved handling.

It is yet another objective of the invention is to addresses this issue by minimizing the unsettling lateral forces experienced by passengers during turns, which not only enhances comfort but also contributes to a smoother ride by absorbing road imperfections more effectively.

The system comprises several innovative components that work synergistically to achieve the desired outcomes. Swing arms, pivotal to the system, are employed as cantilever-type arms that facilitate the tilting action. These arms are connected to a sway bar system that helps distribute ground reaction forces evenly across the vehicle, crucial for maintaining stability during the tilt. Hydraulic cylinders are integrated to control the tilting motion, assisted by shock absorbers that dampen the vibrations caused by uneven road surfaces, thereby enhancing the system’s functionality and the vehicle’s handling characteristics.

Electric motors mounted on the swing arms are responsible for powering the tilting mechanism, ensuring that the system’s response is both quick and efficient. Additionally, the system includes brake discs and calipers strategically placed on the swing arms to provide robust braking capabilities, which are essential for maintaining control during dynamic tilting activities. A controlled manifold is another critical component, tasked with regulating the flow of hydraulic fluid essential for the precise operation of the tilting mechanism.

The innovative design and integration of these advanced components not only redefine traditional vehicular dynamics but also open up new possibilities for automotive design. The Tilting Wheel System’s ability to enhance stability, maneuverability, and comfort positions it as a pioneering solution in the field, addressing the evolving needs of modern vehicles and the demands for safer, more enjoyable driving experiences. 7

Furthermore, the applications of this system extend beyond mere performance enhancements. By improving the dynamic capabilities of vehicles, it allows for the development of safer, more efficient transportation solutions that can adapt to a wide range of road conditions and driving scenarios. Whether in personal passenger vehicles, commercial transport, or specialized vehicles designed for challenging environments, the benefits of the Tilting Wheel System can be leveraged to improve not only individual vehicle performance but also contribute to broader advancements in vehicular technology.

In summary, the Tilting Wheel System with Stability Control stands out as an exemplary innovation in automotive technology, marked by its comprehensive approach to improving vehicle dynamics.
