What is a Telescopic Suspension System?

The telescopic suspension system is used in motorcycles as it is lightweight and best for bikes as it absorbs major shocks from the road. The telescopic Suspension System is also known as the MacPherson strut suspension system. In this article, I will discuss the details and function of the Telescopic Suspension System.

Telescopic Suspension System

The telescopic suspension system is used in motorcycles as they are light in weight. It has springs along the rod to have a better flow of suspension to absorb the road shocks. The telescopic suspension system consists of a shock absorber and a coil spring combined into a single unit. The shock absorber is housed inside a strut assembly, which is a structural component that provides support and serves as a mounting point for various other components.

This is a structural component that typically attaches to the steering knuckle or axle and provides support for the entire suspension system. When someone rides a bike comfort is the main factor. This type of suspension comes with an adjustable spring setup that helps to comfort the bike.

Working of Telescopic Suspension System

When the vehicle hits a bump or experiences any disturbance on the road, the suspension system is compressed or extended. The coil spring absorbs and stores energy during compression and releases it during extension, helping to smooth out the ride.

Simultaneously, the shock absorber works to dampen the oscillations. As the suspension moves, the piston inside the shock absorber moves through hydraulic fluid or compresses gas, generating resistance. This resistance slows down the movement of the suspension, preventing the vehicle from bouncing excessively.

The telescopic suspension system plays a crucial role in maintaining tire contact with the road, providing stability, and ensuring proper handling. By controlling the movement of the suspension, the system contributes to vehicle safety and performance.

Components of Telescopic Suspension System

The telescopic suspension system works on fewer parts like-

1. Coil spring.
2. Strut assembly.
3. Shock absorber.
4. Tightening bolts.
5. Stabilizer bar link.

#1. Coil Spring

The coil spring is a helical spring made of durable material. It is positioned around the strut and provides support for the vehicle’s weight. The coil spring helps absorb shocks and vibrations from the road. These coil springs need to be flexible enough to take the load and absorb the road shock.

#2. Strut Assembly

The strut housing is a structural component that serves as the main support for the entire suspension system. It is usually attached to the vehicle’s body or frame and connects to the steering knuckle or axle. In this assembly, the strut mount is attached.

The strut mount is a connection point between the strut assembly and the vehicle’s body. It allows for some degree of movement and flexibility while maintaining a secure attachment.

#3. Shock Absorber

The strut assembly includes a shock absorber or damper, which is a critical component for controlling the movement of the suspension. The shock absorber helps dampen vibrations and prevents the vehicle from bouncing excessively.

Within the shock absorber, there is a piston connected to the end of the strut. As the suspension moves, the piston moves through hydraulic fluid or compresses gas, generating resistance to control the suspension motion.

#4. Tightening Bolts

The tightening bolts fix the whole telescopic suspension housing in its original place. These tightening bolts need proper tightness for the better movement of the motorcycle.

#5. Stabilizer Bar Link

Some telescopic suspension systems include a stabilizer bar link, which connects the strut to the stabilizer bar (also known as a sway bar). The stabilizer bar helps reduce body roll during cornering.

These components work in tandem to provide a balance between ride comfort and vehicle handling. The coil spring supports the vehicle’s weight, while the shock absorber, housed within the strut assembly, controls the movement and dampens shocks and vibrations. Together, these components contribute to the overall performance and safety of the vehicle’s suspension system.

Advantages of Telescopic Suspension System

The advantages of these types of suspensions are-

1. Telescopic suspension systems are relatively simple in design, which makes them cost-effective to manufacture and install.
2. The repair cost is minimal.
3. The compact design of telescopic suspension systems allows for efficient use of space in the vehicle’s chassis.
4. These suspension systems are straightforward to install, making them a preferred choice for various vehicle models.
5. It provides a good balance between ride comfort and handling.
6. It provides consistent performance across a range of driving conditions.

Disadvantages of Telescopic Suspension System

So, the disadvantages of this system are-

1. These systems typically have limited adjustability compared to more complex suspension designs.
2. Achieving an optimal balance between ride comfort and performance can be challenging with telescopic suspension systems.
3. In certain driving conditions or with heavy loads, telescopic suspension systems may be more susceptible to bottoming out, where the suspension fully compresses and the vehicle comes into contact with the bump stops.
4. For heavy-duty applications, such as large trucks or vehicles designed for off-road use, telescopic suspension systems may not be as well-suited as other suspension designs.
5. Like any suspension system, telescopic systems require regular maintenance. Failure to address worn-out components promptly can lead to a decrease in performance, reduced ride comfort, and potential safety issues.

Conclusion

It’s important to note that while telescopic shock absorbers are a common and effective suspension solution, there are other types of shock absorbers with different designs and applications. The specific design and characteristics of shock absorbers can vary among different vehicle models and manufacturers.

Frequently Asked Questions(FAQ’S)

Why is a dust boot used in telescopic shock absorbers?

The dust boot is a protective cover that prevents contaminants like dirt and debris from entering the shock absorber, ensuring its proper functioning and longevity.

Do telescopic shock absorbers require regular maintenance?

Yes, like any automotive component, telescopic shock absorbers require regular inspection for wear and tear. Worn-out shock absorbers should be replaced promptly to ensure optimal performance and safety.

What are the signs of a failing telescopic shock absorber?

Signs include excessive bouncing, poor handling, uneven tire wear, and a harsh or uncomfortable ride. If any of these symptoms are observed, it’s advisable to have the shock absorbers inspected.
