Technical Field of the Invention

The present invention relates to the field of vehicle dynamics and control systems. Specifically, it pertains to a rear tilting wheel lock system for vehicles that integrates hydraulic, mechanical, and electronic components. The system is designed to enhance stability, maneuverability, and safety during high-speed cornering, operation on uneven terrains, and other dynamic driving conditions. This invention finds applications in motorcycles, three-wheelers, and specialized vehicles, addressing critical challenges in stability and ride comfort through innovative tilt control mechanisms.

Background of the Invention

In modern automotive engineering, stability and maneuverability remain critical factors influencing the safety, performance, and user experience of vehicles. These aspects become particularly challenging in scenarios such as high-speed cornering, uneven terrains, and sudden changes in road conditions. Conventional systems often struggle to adapt dynamically to these challenges, resulting in compromised vehicle control. The inability to ensure consistent stability during sharp turns or on rugged surfaces increases the risk of accidents, reduces driver confidence, and limits the operational scope of vehicles.

This issue is especially pronounced in vehicles with three or fewer wheels, where the lack of inherent stability exacerbates these challenges. Traditional suspension and steering systems do not offer the precision or responsiveness needed to maintain stability in such conditions. As a result, there is a growing need for innovative solutions that address these deficiencies comprehensively.

Over the years, various systems have been developed to improve vehicle stability and maneuverability. Static tilt-lock mechanisms have been employed to address the issue of tilting in certain vehicles. These mechanisms generally involve locking the tilt angle at a fixed position, preventing undesired movement. However, such systems lack the ability to adapt dynamically to varying driving conditions, making them unsuitable for high-performance or all-terrain applications.

Hydraulic systems have also been explored as a means to enhance stability, particularly in tilt control applications. While hydraulic actuation provides the necessary force for tilting operations, prior designs have often suffered from slow response times, mechanical inefficiencies, and synchronization issues. Furthermore, the absence of real-time electronic control systems in these designs limits their adaptability and precision.

Some systems have attempted to integrate electronic controls into tilt mechanisms. These approaches have shown promise but often remain limited in scope due to their complex mechanical designs, high manufacturing costs, and maintenance challenges. The lack of modularity in such systems further restricts their application to specific vehicle types, reducing their overall utility.

The primary disadvantage of existing solutions lies in their inability to provide dynamic, real-time adjustments based on changing road conditions and vehicle dynamics. Static systems fail to offer the responsiveness needed for high-speed maneuvers or uneven terrains, making them unsuitable for modern transportation needs. Hydraulic systems, while powerful, are often hindered by inefficiencies and a lack of integration with electronic controls, resulting in suboptimal performance.

Moreover, many existing systems are complex and difficult to install or maintain. Their non-modular designs complicate integration into different vehicle types, increasing costs and limiting scalability. The absence of safety interlocks and fail-safe mechanisms in these systems poses significant risks, particularly in the event of mechanical or electronic failures.

Another critical limitation is the lack of features to enhance ride comfort. Vibrations and instability during tilting operations not only affect safety but also degrade the overall user experience. Existing systems often neglect these aspects, focusing solely on stability without considering driver and passenger comfort.

Recognizing these challenges, the inventors have identified a dire need for a comprehensive solution that addresses the limitations of existing systems. The ideal solution would provide real-time adaptive tilt control, ensuring optimal stability and maneuverability across diverse driving conditions. It would integrate hydraulic, mechanical, and electronic components seamlessly, offering precision and responsiveness while minimizing complexity.

The inventors also identified the importance of modularity, which allows the system to be easily installed, maintained, and adapted to various vehicle types. Such a design would enhance scalability and reduce costs, making the solution accessible to a broader range of users.

Safety emerged as another critical focus area. The inventors emphasized the need for robust safety interlocks and fail-safe mechanisms to prevent excessive tilting and ensure reliable operation even in the event of system failures. Additionally, the solution needed to enhance ride comfort by reducing vibrations and providing smooth, synchronized motion during tilting operations.

By addressing these identified needs, the inventors aim to set a new standard in vehicle dynamics and stability control. Their innovative approach promises to overcome the limitations of prior art, delivering a versatile, reliable, and user-friendly system capable of transforming the driving experience across a wide range of vehicles and applications.

The invention is detailed comprehensively below with references to the accompanying figures, providing an exhaustive explanation of the structure, components, and operation of the rear tilting wheel lock system. The explanations are designed to showcase the full potential of the system and its applications across various scenarios.

As illustrated in Fig. 2a, the Tilt Master assembly (1) serves as the central component of the rear tilting wheel lock system. This assembly is mounted on the chassis assembly (2) using a pivot mechanism (3). The pivot mechanism provides the Tilt Master assembly with the necessary rotational freedom to allow controlled tilting of the rear wheels. Constructed from lightweight, high-strength materials, the Tilt Master assembly is designed to ensure durability while maintaining a low overall weight for the vehicle.

During operation, the Tilt Master assembly dynamically adjusts the tilt of the rear wheels to enhance stability and maneuverability, particularly during challenging conditions like high-speed cornering. For instance, when a motorcycle equipped with this system enters a sharp curve, the assembly tilts the rear wheels to counteract lateral forces, thereby maintaining balance and ensuring a safe, smooth turn.

The sway bar unit (4), as shown in Fig. 2b, is pivotally connected to the Tilt Master assembly (1). This unit plays a critical role in transferring tilting forces to the swing arm units (5) through two sets of reinforced link sets (6). The link sets, equipped with robust joints and bearings (15), ensure synchronized motion and structural stability during dynamic tilting maneuvers.

For example, when navigating uneven terrains, the sway bar unit ensures that the tilting forces are evenly distributed to both swing arm units, thereby preventing imbalances and ensuring smooth operation. The design of the link sets also allows them to handle high torque and stress, making the system reliable for diverse driving conditions.

As depicted in Fig. 2c, the swing arm units (5) articulate in response to hydraulic actuation provided by the hydraulic cylinder units (7). Each swing arm unit connects to the sway bar unit (4) and the Tilt Master assembly (1), facilitating precise and synchronized tilting motion. Integrated dampers (14) within the swing arm units reduce vibrations, ensuring a comfortable ride for the driver and passengers.

In practical applications, such as off-road driving, the hydraulic cylinder units dynamically adjust the tilt of the swing arm units to maintain stability. For instance, when a three-wheeler equipped with this system traverses rocky terrain, the swing arm units independently adjust to accommodate the uneven surface, ensuring continuous contact with the ground and enhancing vehicle control.

The hydraulic manifold unit (8), shown in Fig. 2d, regulates the flow of hydraulic fluid between the hydraulic cylinder units (7) via hose pipes (9). This manifold is equipped with adjustable flow control valves (13) and a solenoid-controlled mechanism (11), which enable precise and real-time adjustments to the hydraulic system based on vehicle dynamics.

For instance, during high-speed driving, the solenoid mechanism within the hydraulic manifold optimizes hydraulic pressure to lock the tilt angle of the rear wheels. This functionality enhances the vehicle’s stability during sharp turns or rapid lane changes, ensuring safety and control for the driver.

Fig. 2e highlights the electronic control system (10), which interfaces with the hydraulic manifold unit (8) and vehicle sensors. This system processes real-time data, including speed, tilt angle, and road conditions, to optimize the operation of the rear tilting wheel lock system. The solenoid-controlled mechanism (11) in the hydraulic manifold responds to inputs from the electronic control system, dynamically adjusting hydraulic fluid flow to achieve desired tilt and stability.

The electronic control system supports multiple operational modes. For instance, it can switch to a dynamic tilt-lock mode for high-speed cornering or activate a default stability mode for regular driving conditions. This adaptability makes the system highly versatile and suitable for various driving scenarios.

Safety interlocks (12), as illustrated in Fig. 1, prevent excessive tilting beyond predefined safe angles. This feature ensures that the vehicle remains stable and avoids the risk of over-tilting, which could lead to accidents. In addition to the interlocks, a fail-safe mechanism (18) is integrated into the system. This mechanism automatically engages the tilt lock in the event of hydraulic or electronic failure, maintaining the vehicle’s stability under adverse conditions.

For example, if a sensor detects a fault in the hydraulic system while the vehicle is in motion, the fail-safe mechanism activates immediately, locking the tilt and preventing any instability. This redundancy ensures that the system remains safe and reliable at all times.

As shown in Fig. 2c, adaptive shock absorbers (20) are positioned between the swing arm units (5) and the Tilt Master assembly (1). These shock absorbers minimize vibrations and enhance ride comfort, particularly during high-speed or off-road driving. By absorbing impact forces, they prevent discomfort for the driver and passengers and contribute to overall vehicle stability.

For instance, when a vehicle equipped with this system navigates a bumpy road, the adaptive shock absorbers work in conjunction with the hydraulic and electronic components to ensure a smooth ride, reducing driver fatigue and improving safety.

The hydraulic manifold unit (8), as depicted in Fig. 2d, is enclosed within a protective casing (19). This casing safeguards the system from environmental factors such as dust, moisture, and extreme temperatures. Vehicles operating in harsh climates, such as deserts or heavy rain, benefit significantly from this design, as it ensures that the hydraulic and electronic components remain functional and protected from contaminants.

Operational Example
Consider a motorcycle equipped with the rear tilting wheel lock system navigating a mountainous road. As shown in Fig. 2e, the electronic control system (10) receives inputs from sensors detecting the vehicle’s speed and the incline of the road. The solenoid-controlled mechanism (11) in the hydraulic manifold unit (8) adjusts the hydraulic fluid flow, enabling the Tilt Master assembly (1) to tilt the rear wheels dynamically (Fig. 2a). Simultaneously, the sway bar unit (4) and link sets (6) (Fig. 2b) synchronize the motion of the swing arm units (5), ensuring even force distribution. The integrated dampers (14) (Fig. 2c) reduce vibrations, enhancing ride comfort. In the event of a system fault, the fail-safe mechanism (18) activates, locking the tilt and maintaining stability.

This operational example demonstrates the system’s ability to adapt to challenging driving conditions, showcasing its innovative design and functionality.
