Exploring the axles and differentials of the Volvo L120F

We explore the main powertrain components in a loader, using the Volvo L120F as an example. To go even deeper, let’s take a look at some additional aspects and expand with examples from other loaders:

Axle: The Base of the Support

The axles of a Volvo L120F loader are crucial components that ensure the mobility, stability and power of this robust machine. Designed and manufactured to the highest quality standards, these axles play a fundamental role in the daily performance of the loader.

Main functions of the axes:

Weight support: The axles support the total weight of the loader, including the machine itself, the load in the bucket and any additional accessories.
Power Transmission: The axles transmit power from the engine to the wheels, allowing the loader to move forward, backward, twist and turn on its own axis.
Shock Absorption: The axles absorb impacts and vibrations from the ground, protecting the machine and operator from damage.
Steering: The axles allow the loader to turn and maneuver with precision.

Differentials: Adapting to Every Terrain

The differential is a crucial part of the machine’s transmission system. Its main function is to allow the tyres to rotate at different speeds when the machine is turning or cornering. This helps maintain traction and prevents excessive wheel slip.

Differential components:

Crown and pinion gears: These gears are located inside the differential. The ring gear is a large sprocket that connects to the drive shaft, while the pinion is connected to the output shaft to the wheels. Together, they allow the distribution of power between the wheels.
Satellites and planetaries: Satellites are small gears that rotate around planetary gears. The planetaries are connected to the pinion and the ring gear. When one tyre spins faster than the other (for example, in a curve), the satellites allow the planetary gears to move, adjusting the speed of the wheels.
Differential housing: It is the structure that contains all the components mentioned above. It also provides support and protection.

Functioning:

When the machine turns, the differential allows the outside wheels to spin faster than the inside wheels. This prevents slipping and improves traction. If one wheel loses traction (for example, on slippery terrain), the differential redirects power to the wheel with the best grip.
In short, the differential is essential for the stability, handling and traction of the Volvo L120F. Without it, the wheels would not be able to rotate independently, making operation on varied terrain difficult.

Types of differentials

Open Differential: This is the most common type of differential and allows the wheels to spin at different speeds. However, it can allow one wheel to spin faster than the others, which can lead to uneven tire wear and loss of traction.
Locking Differential: This type of differential locks the wheels to rotate at the same speed, which improves traction on difficult terrain. However, it should not be used on hard surfaces as it may damage the drivetrain.
Limited Slip Differential: This type of differential combines the features of open and locked differentials. It allows the wheels to spin at different speeds up to a point, but then locks up when more traction is needed.

What boosts our machines? A glimpse into a key element: The transmission

When we think of heavy machinery, we imagine an imposing power capable of moving earth, gravel, and stone with ease. But behind this vision, there is much more: achieving a longer lifespan with lower maintenance costs. In recent years, heavy machinery has evolved significantly to meet these demands. In this blog, we will explore the heart of these machines, the transmission. With a focus on wheel loaders, we will break down their key components, the fluids that keep them running, and their types.

Emphasizing Their Importance

Transmissions are the backbone of machines, allowing for the efficient transfer of engine power to the wheels or tracks. In a wheel loader, the transmission plays an essential role in adjusting speed and torque (the rotational force a motor can generate to perform work) according to operational needs.

And in the case of a wheel loader… What aspects do we highlight?

Essential Components of a Loader’s Transmission

Torque Converter

The torque converter is the first piece in a wheel loader‘s transmission. It functions as a hydraulic coupling that allows for the smooth and gradual transmission of power generated by the engine to the transmission. Its design enables jerk-free starts and efficient energy transfer. In situations of heavy loading, the torque converter acts as a torque multiplier, providing greater force to overcome obstacles and challenging terrains.

Gearbox (Powershift)

The gearbox, or powershift transmission, enables control of speeds and gear changes in the wheel loader. The distinctive feature of a powershift transmission is its ability to shift gears seamlessly, ensuring a smooth transition without power loss. It also allows the operator to adapt the machine, such as a wheel loader, to different load and terrain conditions, optimizing efficiency and performance in various tasks.

Axles and Driveshafts

Axles and driveshafts serve as crucial foundations in wheel loaders, playing an essential role in transferring the power generated by the engine to the wheels. Axles, designed to withstand loads and torsion, are responsible for maintaining precise wheel alignment and ensuring reliable traction on diverse terrains. Driveshafts, on the other hand, act as vital intermediaries by seamlessly transmitting motion from the gearbox to the axles.

The synergy between these components is fundamental for the optimal performance of the wheel loader, especially in construction, mining, and earthmoving environments.

Keeping them in optimal condition is a priority to ensure the reliability and efficiency of the machine throughout its lifecycle.

Fluids and Lubrication

In the past, powershift transmissions used to rely on engine oil, which was not an optimal choice due to differences in composition and performance required by transmissions. Compared to specialized oils, engine oils could lead to wear and friction issues in components such as clutches and brakes. Changes in fluid technologies and design have given rise to advanced oils that enhance performance and durability.

These modern lubricants fulfill several vital functions, including ensuring friction stability, anti-wear protection, and material compatibility. They also provide control over sludge, protection against rust and corrosion, and thermal stability.

You can choose between single-grade or multigrade oils, depending on the climate and requirements. As the industry evolves, oils will continue to adapt to new engines and emission requirements, remaining essential in maximizing the efficiency and longevity of heavy machinery.

Typology

In the realm of wheel loaders and most heavy machinery, we encounter a variety of transmission types, each designed to meet specific needs and situations:

Powershift: Renowned for its seamless gear shifts, allowing the machine to maintain its momentum and efficiency while changing speeds. Extremely useful in situations of constant load or on uneven terrains. The smooth transition between gears optimizes operation in various conditions, providing greater traction and reducing clutch wear. In construction and mining environments where power and durability are essential, they have proven to be an effective choice.

Hydrostatic: Hydrostatic transmissions employ hydraulic fluids to transmit engine power to the wheels or tracks. This technology offers precise control and smooth maneuverability, making it particularly valuable for operations requiring precise movements and maneuvers in tight spaces. The ability to vary speed and direction smoothly and continuously makes hydrostatic transmissions ideal for accurately loading and unloading materials in congested work areas.

Automatic: Automatic transmissions, known for their comfort and ease of use in passenger vehicles, have also been adapted for heavy machinery, including wheel loaders. These transmissions automatically shift gears based on load conditions and machine speed, allowing operators to focus on other critical tasks. Efficiency and the smoothness of gear transitions are standout features of this transmission type, resulting in a more comfortable and productive operation.

Recycling and Sustainability

The recycling of used transmission components plays an essential role in reducing environmental impact and promoting sustainability in the industry. Firstly, recycling helps minimize the accumulation of electronic and metallic waste, reducing pressure on landfills and preventing soil and water pollution. By salvaging and reusing parts from decommissioned transmissions, the need to extract and process new raw materials is decreased, contributing to the conservation of natural resources.

Additionally, it can have a positive impact on the economy by fostering job creation in the recycling and refurbishment industry. Workshops and specialized companies in parts recovery can repair and refurbish used components, extending their lifespan and offering them at a more affordable cost compared to entirely new parts. This benefits both heavy machinery operators and fleet owners by reducing maintenance and replacement costs.

Lastly, it contributes to a circular economy mindset in the industry, where products and materials are reused and recycled instead of being discarded after their initial lifespan. This not only reduces the industry’s environmental footprint but also promotes greater awareness of the importance of resource conservation and environmental responsibility in a critical sector for construction and infrastructure.

Buying a new machine or thinking about alternative solutions like leasing, renting or repairing?

When the machine used for earthmoving breaks down, what are the alternative solutions that the owner has?

Buying new construction machinery certainly has its advantages if you have the right budget.

When the budget is limited, you can repair the machine and, in the meantime, you can opt for a rental option. Repair can be done with new or recycled spare parts.

Many users do not like the idea of replacing their old machine with a new one, both for economic reasons and for reasons of difficulty in learning new technologies. If the operator uses the machine well and is productive, a repair is a good solution.

Some owners, for example, would choose to repair any component with the goal of maximizing the overall life expectancy of their machine. Continue reading Buying a new machine or thinking about alternative solutions like leasing, renting or repairing?

Increase machine productivity and efficiency through spare parts management

Any component with moving parts has a limited life cycle.

A construction machine owner should consider a well-planned spare parts system having the right spare parts. Having parts on hand offers a greater chance of eliminating unwanted downtime.

When the machine stops, the losses are multiple, such as employee inactivity, lost of contracts and orders, just to name a few.

It should not be overlooked that in the event that the machine stops due to a breakdown, the inability to have the correct replacement parts can lead to higher costs. For example such as the additional costs of requesting a fast delivery or the safety risk by implementing an improper repair to try to get the machine working again without the proper replacement.

Having a basic supply of spare parts on hand can reduce the risks and problems identified above.

But how do you know which spare parts a heavy machine owner should always have available?

First, it is necessary to identify which machines have the greatest impact on production. Consequently, focusing on older machines that are no longer in production, as replacement parts can be difficult to obtain. It is very important consider when request parts, especially at short notice, and therefore forced to go to the non–genuine parts market of usually poor quality.

Therefore, the objective of spare parts management should be to ensure the lowest possible overall cost, both in economic terms and in terms of productivity.

Spare parts management is a determining factor for better machine efficiency.

Maintenance of machines and organization of spare parts

Routine maintenance implies the need to organize an efficient system of available spare parts. An understanding of which cannot be dispensed whit.

For scheduled maintenance, on the other hand, spare parts must be requested within a specified period. For these, it is useless to manage the warehouse, it is rather useful to know the life cycle of each important component for the functionality of the machine.

What can the maintenance manager do to keep everything under control?

First, you must generate consumption statistics and then maintain a close collaboration with the suppliers of the parts to ensure their availability with acceptable delivery times. In addition, you must constantly communicate with maintenance technicians to know the status of machines in real time and classify spare parts according to their strategic importance.

Therefore, it is advisable to always have the so-called critical spare parts available, that is, those that reduce machine downtime due to breakdowns.

It is understandable that a company does not have the financial availability to buy, for example, a transmission or an engine and keep them in stock. But a machine which doesn’t work cannot be afforded.

To overcome these problems, you can contact Taop Parts. We have thousands of spare parts available for machines such as wheel loaders, excavators, dump truck, bulldozers, backhoe, loaders etc.

Taop Parts offers recycled, original, verified and reliable spare parts that save money for the machine owner, but above all it gives you the opportunity to have your own warehouse for spare parts, especially for critical ones.

Hydraulic cylinder: types and operating

Taop Parts offers hydraulic cylinders recovered from original machines, which have been tested and are ready to be installed.

Hydraulic cylinders are important components in earth-moving machines, such as excavators and wheel loaders, as they transform hydraulic force into linear movement, by facilitating the lifting and moving of heavy materials.

The cylinder works thanks to the hydraulic system, consisting of pumps, pipes and hydraulic fluid.

A hydraulic cylinder is a tube closed at one end with a rod that moves inside. Inside the cylinder we find a piston. The piston separates the internal side of the cylinder from the external one. The fluid moves to both sides of the cylinder to extend or retract the rod.

Hydraulic cylinders can push, pull and lift different types of loads with different weights and sizes.
