Extreme temperatures and suspension performance: what to know

Climatic conditions represent one of the most important challenges for industrial vehicles. Intense heat, frost and strong temperature variations can affect the behavior of numerous mechanical components, including suspensions.

Understand the relationship between extreme suspension temperatures it is essential to guarantee safety, comfort and operational continuity throughout the year. The suspensions, in fact, work constantly to absorb road stress and keep the vehicle stable, regardless of environmental conditions.

Because temperature affects suspension

Each mechanical component reacts to temperature variations.

In the case of suspensions, climatic conditions can influence:

elastic materials;
rubber components;
fluids inside the shock absorbers;
air springs;
support systems.

Particularly high or very low temperatures can change the behavior of these elements and affect the overall performance of the vehicle.

Suspensions during the summer

In the warmer months, trucks and industrial vehicles are often subjected to long journeys with high asphalt temperatures.

Heat can increase stress on components and accelerate some wear phenomena.

In particular:

shock absorbers work at higher temperatures;
elastic materials are subjected to greater stress;
some rubber components may deteriorate more quickly.

For this reason it is important to periodically monitor the status of suspensions during the summer season.

Suspensions during the winter

Cold can also affect the behavior of the suspension system.

Particularly low temperatures can make some materials less elastic and change the response of certain components.

Among the most common effects we find:

greater initial stiffness;
lower vibration absorption capacity;
additional stresses on the most worn components.

In industrial vehicles operating in areas subject to severe frost, regular checks become even more important.

The impact on the air springs

The air suspension is designed to ensure high levels of comfort and stability.

However, air springs can also be affected by extreme weather conditions.

Significant temperature changes can contribute to:

pressure variations;
material stress;
accelerated wear of already deteriorated components.

Preventive maintenance allows you to promptly identify any anomalies and maintain high system performance.

Shock absorbers and climatic conditions

Shock absorbers play a fundamental role in controlling vehicle oscillations.

During their operation, the energy generated by the movements of the suspensions is transformed into heat.

When the vehicle operates in particularly hot or cold environments, the component is called upon to work in even more demanding conditions.

For this reason, the construction quality and reliability of the shock absorber become crucial elements to guarantee constant performance over time.

How to protect your suspension from extreme conditions

Reducing the impact of extreme temperatures is possible through correct maintenance.

Recommended activities include:

periodic checks of the shock absorbers;
checking the air springs;
media inspection;
monitoring of the general conditions of the suspensions;
timely replacement of worn components.

Scheduled maintenance allows you to prevent breakdowns and improve the operational continuity of the vehicle.

Reliability and operational continuity

In the truck sector, every vehicle downtime entails costs and loss of productivity.

For this reason it is important to use components designed to cope with complex operating conditions and ensure reliable performance throughout the year.

Way Assauto supports spare parts dealers and distributors with a range of aftermarket components for industrial vehicles developed to offer quality, reliability and operational continuity even in the most demanding conditions of use.

The relationship between extreme suspension temperatures it is often underestimated, but can significantly influence the behavior of the vehicle and the life of the components.

Intense heat and extreme cold subject the suspension system to additional stress which makes regular maintenance and the use of reliable components even more important.
