Description:DESCRIPTION
Technical Field of the invention

The present invention generally relates to vehicle suspension and braking systems. More particularly, it pertains to a rear tilting wheel system with a swing arm mechanism designed to provide controlled braking and enhanced stability in vehicles

Background of the invention

In the modern automotive landscape, achieving optimal stability and braking efficiency remains a persistent challenge, particularly in vehicles operating under dynamic conditions such as high-speed maneuvers, sharp cornering, or uneven terrain. Traditional vehicle suspension systems, often characterized by rigid or semi-rigid rear axle configurations, fail to provide the flexibility required for maintaining consistent tire-road contact during cornering. This limitation directly impacts vehicle stability, traction, and overall safety, leading to a heightened risk of skidding or losing control.

Similarly, conventional braking systems, which rely on mechanical or basic hydraulic designs, struggle to distribute braking force evenly across the brake discs. Uneven force application not only reduces braking efficiency but also results in accelerated wear of critical components such as brake pads and discs. This uneven wear increases maintenance costs and decreases the overall reliability of the braking system. Moreover, prolonged or aggressive braking often generates excessive heat, leading to brake fade, reduced stopping power, and a compromised safety margin during extended use.

These combined challenges—insufficient stability during cornering and unreliable braking performance—pose significant risks to vehicle operators and passengers. As modern vehicles become increasingly versatile and expected to perform across diverse driving conditions, these limitations demand innovative solutions.

Over the years, numerous efforts have been made to improve vehicle stability and braking performance. Traditional rear suspension systems often employ rigid axles or independent suspension designs that allow for limited vertical movement of the wheels. While these systems provide adequate performance for standard driving conditions, they lack the ability to dynamically adapt to changing road surfaces or cornering forces. For example, double-wishbone and multi-link suspension systems have been widely adopted for improving vertical wheel articulation, but their designs do not address the issue of dynamic wheel tilting, which is critical for maintaining traction during high-speed cornering.

In the realm of braking systems, hydraulic and disc brakes have become industry standards for their efficiency and reliability. Innovations such as anti-lock braking systems (ABS) and electronic brake force distribution (EBD) have further enhanced braking performance in many vehicles. However, these systems primarily focus on electronic control and fail to address the mechanical and structural limitations inherent in the brake calipers and discs. Additionally, existing designs often overlook the integration of braking systems with dynamic suspension elements, resulting in suboptimal coordination between stability and braking.

Another area of prior art involves the use of swing arm mechanisms, which are commonly found in motorcycles and some all-terrain vehicles (ATVs). While these mechanisms allow for limited rear wheel articulation, they are primarily designed for absorbing shocks and do not provide the dynamic tilting functionality needed to maintain stability during aggressive maneuvers. Furthermore, the integration of swing arms with advanced hydraulic braking systems has been largely unexplored in conventional designs.

Despite these advancements, existing solutions fail to fully address the combined challenges of dynamic stability and braking efficiency, particularly in vehicles requiring precise control under demanding conditions.

Existing vehicle suspension and braking systems exhibit several critical disadvantages that limit their effectiveness in modern applications. One major drawback is the lack of dynamic wheel tilting. Conventional suspension designs focus on vertical wheel articulation but do not provide the lateral adaptability required to maintain optimal tire-road contact during cornering. This limitation compromises traction, particularly in high-speed or sharp-turn scenarios, and increases the risk of skidding or instability.

Another significant disadvantage is the uneven distribution of braking force in traditional systems. Mechanical or basic hydraulic designs often fail to apply uniform pressure across brake discs, resulting in inefficiencies in braking performance. This uneven force application accelerates the wear of brake pads and discs, increasing maintenance requirements and operational costs. Furthermore, inconsistent braking force can lead to unpredictable stopping behavior, posing safety risks for drivers and passengers.

Heat dissipation is another area where conventional braking systems fall short. The inability to manage thermal loads effectively during prolonged or aggressive braking operations leads to brake fade, a condition where braking performance deteriorates due to overheating. This issue is particularly problematic in high-performance or heavily loaded vehicles, where consistent stopping power is critical.

Additionally, traditional systems often suffer from high maintenance costs due to the rapid wear of components like brake pads, discs, and suspension elements. The frequent replacement of these parts not only increases operational expenses but also disrupts vehicle availability, making such systems less practical for intensive or high-demand applications.

The limited versatility of existing systems is another disadvantage. Most designs are tailored for specific vehicle types, lacking the adaptability to function effectively across diverse applications. This rigidity restricts their use in vehicles that require a combination of dynamic stability and braking efficiency, such as all-terrain vehicles, urban delivery fleets, or race cars.

Finally, there is a lack of effective integration between suspension and braking systems in current designs. These systems are typically developed as independent modules, resulting in poor coordination during dynamic maneuvers. This disconnect undermines the overall performance and safety of the vehicle, particularly in challenging driving conditions.

The inventors recognized the critical need for a unified solution that addresses the combined challenges of dynamic stability and braking efficiency. They observed that existing systems, while adequate for basic applications, fail to meet the demands of modern vehicles operating under diverse and challenging conditions. This realization led to the conceptualization of a rear tilting wheel system integrated with a swing arm mechanism and advanced hydraulic braking technology.

The present invention relates to a rear tilting wheel system (100) with a swing arm mechanism that ensures controlled braking and enhanced vehicle stability. Referring to the accompanying figures, the invention’s structure and operation are described in detail, demonstrating its practical applications and technological advantages.

As shown in Figure 1, the chassis assembly (6) forms the foundational structure of the invention. It is designed to withstand dynamic forces generated during braking and tilting motions while maintaining the overall stability of the system. The chassis is constructed from materials such as high-strength steel or lightweight aluminum alloys, which provide the necessary balance between durability and weight reduction.

The chassis assembly (6) includes mounting points for attaching critical components, such as the swing arms (7, 8), the brake master unit (10), and the hydraulic hose pipes. These attachment points are precision-engineered to ensure the secure integration of all components. For example, during high-speed maneuvers, the chassis serves as the anchor for the swing arms, enabling smooth tilting motion without compromising structural integrity. The robust design of the chassis assembly enhances the vehicle's ability to maintain stability even under extreme conditions, such as aggressive cornering or uneven terrain.

The swing arm mechanism (7, 8), depicted in Figure 2a, is a pivotal feature of the invention. These swing arms are pivotally attached to the chassis assembly (6) via reinforced pivot joints and precision-engineered bearings. The swing arms enable the dynamic tilting motion of the rear wheels, ensuring optimal tire-road contact during cornering and high-speed maneuvers.

Each swing arm (7, 8) is constructed from corrosion-resistant materials like forged aluminum alloys or high-strength steel. These materials provide the necessary durability to withstand prolonged use while keeping the overall weight of the system low. The pivot joints are sealed to prevent the ingress of dirt, debris, or moisture, ensuring smooth operation under various environmental conditions.

For instance, during a sharp turn, the swing arms tilt the rear wheels inward, improving traction and stability. This dynamic tilting action allows the vehicle to adapt to lateral forces, reducing the risk of skidding or losing control. The swing arms are further equipped with dampening mechanisms that absorb vibrations, enhancing ride comfort and stability on rough or uneven surfaces.

The hydraulic braking system, illustrated in Figure 2b, is another critical component of the invention. The brake master unit (10) is securely mounted on the rear side of the chassis assembly (6). This unit includes a hydraulic piston and a fluid reservoir, both designed to generate consistent hydraulic pressure. The generated pressure is transmitted to the brake calipers (11) through reinforced hydraulic hose pipes.

A key feature of the braking system is the fulcrum lever mechanism, which amplifies the force applied by the operator via the left brake lever. This amplification ensures efficient engagement of the hydraulic piston within the brake master unit (10), allowing for precise and responsive braking control. For example, during a sudden stop, the fulcrum lever mechanism ensures that the hydraulic pressure is distributed evenly, minimizing the risk of skidding and maintaining vehicle stability.

As shown in Figure 2c, the brake calipers (11) are mounted on the swing arms (7, 8) and aligned with the brake discs (12), which are rotationally coupled to the rear wheels. The brake calipers apply uniform force on the brake pads, ensuring consistent engagement with the brake discs. This uniform force distribution minimizes wear on the components, extending their lifespan and improving overall braking efficiency.

The brake discs (12) are designed for high durability and effective heat dissipation. These discs are made from materials such as cast iron or carbon composites and feature vented or slotted designs that enhance thermal performance. During prolonged braking operations, these features prevent overheating, ensuring reliable performance and reducing the risk of brake fade. For instance, during downhill driving or aggressive braking, the vented brake discs dissipate heat efficiently, maintaining consistent stopping power.

The strategic positioning of the brake calipers on the swing arms ensures dynamic distribution of braking force. This configuration allows the braking system to adapt to the tilting motion of the rear wheels, providing enhanced control and safety during cornering or sudden stops.

Referring to Figure 2d, the hydraulic hose pipes play a crucial role in transmitting hydraulic pressure from the brake master unit (10) to the brake calipers (11). These hoses are constructed from reinforced materials, such as braided synthetic rubber or stainless steel, to ensure reliability under high-pressure conditions. The hoses are also coated with wear-resistant and corrosion-resistant materials, providing durability and protection against environmental factors.

The flexible design of the hydraulic hose pipes accommodates the dynamic motion of the swing arms (7, 8) during tilting. For example, as the swing arms pivot to adjust the rear wheels' angle during cornering, the hydraulic hose pipes maintain uninterrupted fluid transmission, ensuring consistent braking performance. This feature is particularly beneficial in off-road or rugged environments, where the system must adapt to varying terrains.

The left brake lever mechanism, shown in Figure 2e, serves as the primary interface between the operator and the braking system. Ergonomically designed, the brake lever allows the operator to apply braking force with minimal effort. The lever is connected to the fulcrum lever mechanism, which transmits and amplifies the applied force to engage the hydraulic piston within the brake master unit (10).

For example, during an emergency stop, the operator's input at the brake lever is efficiently amplified by the fulcrum mechanism, ensuring quick and responsive braking action. The brake lever is constructed from lightweight yet durable materials, such as aluminum alloys, reducing operator fatigue while maintaining structural integrity.

The integration of the swing arm mechanism and hydraulic braking system allows for seamless operation. For instance, during a high-speed turn, the swing arms (7, 8) dynamically tilt the rear wheels, maintaining optimal road contact. Simultaneously, the hydraulic braking system ensures uniform force application to the brake discs (12), enhancing stability and stopping power. This coordinated action minimizes the risk of skidding and improves vehicle handling, particularly in challenging driving conditions.

Example
Consider a motorcycle equipped with the rear tilting wheel system navigating a sharp curve on a wet road. As the rider initiates the turn, the swing arms (7, 8) tilt the rear wheels inward, improving traction and stability. The rider applies the brakes using the left brake lever mechanism, and the fulcrum lever amplifies the applied force, engaging the hydraulic piston within the brake master unit (10). Hydraulic pressure is transmitted through the reinforced hose pipes to the brake calipers (11), which uniformly engage the brake discs (12). The vented brake discs dissipate the heat generated during braking, maintaining consistent performance throughout the maneuver. This integrated functionality ensures the rider safely navigates the turn without losing control.

The invention is highly versatile and can be adapted for various vehicle types. In motorcycles and scooters, the system enhances handling and safety during sharp turns and high-speed rides. For all-terrain vehicles (ATVs), it provides improved stability and control on uneven terrain. High-performance vehicles benefit from the system’s precise braking and enhanced stability, particularly during aggressive maneuvers. In urban delivery vehicles, the system’s responsive braking and maneuverability enhance performance in crowded city environments.

The present invention represents a significant advancement in vehicle technology by integrating a dynamic rear tilting wheel system with an advanced hydraulic braking mechanism. The system’s innovative features, such as the swing arm mechanism (7, 8), brake master unit (10), hydraulic hose pipes, and ergonomic brake lever mechanism, provide superior stability, braking efficiency, and adaptability. Referring to the detailed figures and practical examples, the invention demonstrates its potential to transform modern automotive systems, making vehicles safer and more reliable across diverse applications.

The chassis assembly (6), which forms the structural backbone of the system, is fabricated using high-strength steel or lightweight aluminum alloys. The choice of material depends on the intended application, with steel offering superior rigidity and aluminum providing a weight advantage. The chassis is crafted using advanced techniques such as CNC machining and robotic welding to achieve precision and structural integrity. Mounting points for the swing arms (7, 8), brake master unit (10), and other components are machined to exact specifications to ensure proper alignment and secure attachment.

After fabrication, the chassis undergoes surface treatments such as powder coating, anodizing, or electroplating to enhance corrosion resistance and durability. A comprehensive quality inspection, including dimensional analysis using coordinate measuring machines (CMMs), ensures the chassis meets stringent performance standards before proceeding to the assembly phase.

The swing arms (7, 8) are pivotal components that enable the dynamic tilting of the rear wheels. These are forged from high-strength steel or corrosion-resistant aluminum alloys to withstand the dynamic loads experienced during operation. The forging process is followed by precision machining to ensure the pivot points align perfectly with the chassis assembly (6). Bearings and dampening mechanisms are integrated into the swing arms to facilitate smooth tilting motion and reduce vibrations.

To extend the lifespan of the swing arms, anti-corrosion coatings such as anodizing or powder coating are applied. Sealed pivot joints are then assembled to protect against dirt, debris, and moisture, ensuring consistent performance even in harsh environmental conditions. This stage concludes with a rigorous inspection to verify the swing arms’ structural and functional integrity.

The brake master unit (10), a key component of the hydraulic braking system, is fabricated with precision to maintain consistent hydraulic pressure. The unit includes a hydraulic piston and a fluid reservoir, which are machined from lightweight and corrosion-resistant materials such as aluminum or stainless steel. The fulcrum lever mechanism is then assembled and integrated into the master unit. This mechanism amplifies the operator’s input force, ensuring effective hydraulic pressure generation.

Each assembled brake master unit is subjected to pressure testing to confirm its ability to generate and maintain consistent hydraulic performance. This step is critical to ensuring the reliability of the hydraulic braking system under high-pressure conditions.

The brake calipers (11), which apply braking force to the brake discs (12), are precision-machined from high-strength aluminum or magnesium alloys. These materials provide the necessary balance between durability and weight. Hydraulic channels within the calipers are carefully machined to ensure smooth fluid flow and consistent braking performance. To enhance thermal resistance, heat-dissipating coatings are applied to the calipers.

The brake discs (12) are fabricated from materials such as cast iron or carbon composites, selected for their excellent thermal conductivity and durability. Advanced machining techniques are employed to create vented or slotted designs, which improve heat dissipation and reduce the risk of brake fade. The discs undergo surface finishing processes to ensure smooth interaction with the brake pads, optimizing braking efficiency. Once fabricated, the brake calipers and discs are assembled and tested for alignment, force distribution, and thermal performance.

The hydraulic hose pipes are manufactured using reinforced synthetic rubber or braided stainless steel to withstand high-pressure hydraulic fluid transmission. These materials are chosen for their flexibility and durability, enabling the hoses to accommodate the dynamic motion of the swing arms (7, 8) during operation. The hoses are fitted with precision-engineered connectors to ensure leak-proof attachment to the brake master unit (10) and brake calipers (11).

Each hydraulic hose undergoes rigorous pressure testing to verify its ability to handle high fluid pressures without leaks or ruptures. The hoses are further treated with abrasion-resistant and corrosion-resistant coatings to extend their operational lifespan.

The left brake lever mechanism, which serves as the operator’s interface with the braking system, is fabricated from lightweight and durable aluminum alloys. The lever is designed with an ergonomic shape to reduce operator fatigue while maintaining structural integrity under repeated use. The fulcrum lever mechanism is integrated into the brake lever assembly, ensuring efficient force amplification and responsive braking control.

Once assembled, the brake lever mechanism is tested for ease of use and reliability, ensuring it performs consistently under various operating conditions.

In the final stage, all components are integrated into the chassis assembly (6). The swing arms (7, 8) are attached to the chassis using pivot joints, and the hydraulic braking system is installed with the brake master unit (10) connected to the hydraulic hose pipes and brake calipers (11). The brake discs (12) are mounted onto the rear wheels, ensuring precise alignment with the calipers.

During this stage, dynamic adjustments are made to ensure the swing arms function seamlessly with the braking system. The integration process is followed by a comprehensive quality control procedure, including tests for tilting functionality, braking efficiency, and system reliability under simulated real-world conditions.
