The dual suspension system is an important design in bicycle suspension systems. By simultaneously using two shock absorbers, it provides better damping effect and stability in high-intensity scenarios such as mountain biking and competitive cycling. This article will delve into the working principles, advantages, and suitable scenarios of the dual suspension system, helping cycling enthusiasts to better understand and choose the appropriate suspension system.
Development of Dual Suspension Systems
• Traditional bicycle suspension system: Before the development of dual suspension systems, bicycles typically used rigid suspension systems. These systems consisted of a rigid front fork and a sturdy rear axle, which could not provide sufficient shock absorption.
• Introduction of spring suspension systems: With an increasing demand for riding comfort, spring suspension systems were introduced to bicycles. These systems use springs to absorb the impact from uneven road surfaces and provide a certain level of shock absorption.
• Emergence of single shock absorber systems: To further enhance the shock absorption performance of bicycles, single shock absorber systems were introduced. These systems use a shock absorber on the front fork or rear axle, employing hydraulic or spring mechanisms to provide better shock absorption.
• Development of dual shock absorber systems: In order to further improve the shock absorption performance and stability of bicycles, dual shock absorber systems were introduced. These systems utilize two shock absorbers, one on the front fork and one on the rear axle, combining the main shock absorber and the auxiliary shock absorber to provide better shock absorption and control performance.
Working Principles of Dual Suspension Systems
1. Road Impact Absorption: Dual shock absorbers refer to a design that uses two shock absorbers in the rear suspension of a bicycle. These two shock absorbers are usually connected to the frame by connecting rods and are connected to the upper and lower rear wheels respectively.When a bicycle traverses uneven terrain, such as bumps, potholes, or obstacles, these impacts are transmitted to the frame and rear wheel. The dual suspension system utilizes two shock absorbers that work together to absorb and reduce these impacts from the ground.
2. Function of the Shock Absorbers: The shock absorbers, which consist of hydraulic or spring mechanisms, play a crucial role. When the wheel encounters uneven surfaces, the shock absorbers rapidly respond by compressing or extending, thereby absorbing the impact and controlling the frame's motion through damping.
3. Motion Control: The dual suspension system also offers excellent motion control. By coordinating the action of the two shock absorbers, precise control over the frame's motion in various road conditions is achieved. This includes lateral tilting, vertical undulations, and rear wheel traction. Such control enhances stability, maneuverability, and provides a more comfortable and safe riding experience for the cyclist.
The Development of Dual Suspension System on Electric Bicycles
The use of dual suspension technology on electric bicycles began in the early 21st century.
The adoption of dual suspension systems on electric bicycles is primarily due to the significant increase in speed compared to traditional bicycles, as well as the fact that bicycles are often ridden on urban roads. This means that bicycles need to cope with more uneven surfaces, sudden changes in terrain, and other obstacles, requiring a better suspension system to ensure smooth and safe riding. The application of dual suspension systems emerged in response to these needs.
The dual suspension system on electric bicycles consists of front and rear components. The front suspension is typically installed on the bicycle fork and uses either springs or hydraulic systems to absorb impacts from the road. The rear suspension is usually mounted on the bicycle's rear axle and employs similar methods to reduce shocks to the rider and improve comfort. Through the collaborative action of these two components, the dual suspension system effectively reduces the impact from the road surface, allowing riders to enjoy a comfortable driving experience in different road conditions.
Mature Dual Suspension Design Offers Several Advantages
1. Enhanced riding comfort: Electric bicycles are typically heavier than traditional bicycles and can create more significant vibrations when riding at high speeds or on uneven surfaces. The introduction of a dual suspension system effectively reduces the impact caused by uneven road surfaces, providing a smoother and more comfortable riding experience. Riders can experience reduced fatigue during long rides and enjoy improved stability and comfort.
2. Increased load-bearing capacity of the suspension system: Electric bicycles have higher weight and greater power output, demanding a stronger load-bearing capacity from the suspension system. A dual suspension system, utilizing two shock absorbers, distributes and absorbs the impact from the weight and power output of the electric bicycle, resulting in improved suspension performance and durability.
3. Improved vehicle stability and control: High-speed riding and sudden braking pose challenges to the stability and control of electric bicycles. A dual suspension system better controls the vehicle's posture and reduces suspension rebound, providing a more stable riding experience. This is particularly crucial for high-speed riding, cornering, and off-road cycling, enhancing safety and rider confidence.
4. Greater versatility: The dual suspension system's superior shock absorption and stability make it suitable for intense scenarios such as heavy-duty mountain biking, competitive cycling, and off-road riding. In these situations, bicycles encounter harsher road conditions and greater challenges; the dual suspension system provides riders with enhanced confidence and comfort.
5. Improved overall quality and competitiveness: Introducing a dual suspension system raises the technological content and high-end appeal of electric bicycles, enhancing their overall quality and competitiveness. As consumer demands for comfort and stability continue to rise, the dual suspension system, as an innovative technology, meets their expectations and improves the market competitiveness of electric bicycles.
Currently, dual suspension technology has become a standard configuration in the electric bicycle industry. Whether for urban commuting or rural riding, dual suspension is essential for delivering a comfortable driving experience. Furthermore, as technology advances, dual suspension systems continuously improve. For example, the addition of an electronic control system allows for automatic adjustment of shock absorption intensity based on road conditions, making the system smarter and more convenient.
However, it is worth noting that the dual suspension system is not without drawbacks, such as increased weight and higher maintenance costs. Nevertheless, due to its outstanding performance, the dual suspension system remains an indispensable feature for electric bicycles.
How to Choose a Suitable Dual Suspension System?
Choosing a suitable dual suspension system requires considering factors such as personal needs, riding style, and budget:
1. Riding needs: Firstly, consider your riding needs, whether it is heavy-duty mountain biking, competitive cycling, or casual leisure riding. Different riding needs determine different requirements for suspension performance and stability.
2. Suspension system type: Dual suspension systems come in different designs and constructions, such as VPP (Virtual Pivot Point) suspension system, four-bar linkage suspension system, etc. Understanding the characteristics and advantages of various suspension systems helps in choosing the right type for oneself.
3. Brand and quality: Choosing reputable brands for dual suspension systems ensures product quality and reliability. At the same time, it's important to inquire about the product's after-sales service and warranty policy.
4. Budget considerations: Dual suspension systems vary in price. Choose a product that fits your budget. However, it's essential not to solely focus on price and overlook the product's performance and quality.
Conclusion
As an important design of bicycle suspension systems, dual suspension systems provide better shock absorption and stability, making the riding experience more comfortable and safe. Choosing a suitable dual suspension system requires considering factors such as personal needs and budget. Through this article, it is hoped that readers can better understand and choose the suspension system that suits them, and enjoy a superior riding experience.
