Volvo articulated dump trucks with high cross-country ability

Design features of the Volvo A35F truck

This design facilitates the rotation of the sections relative to each other and provides the heavy machine with the ability to “fold” horizontally. As a result, the load on the frame part is reduced, and the truck wheels are almost always in contact with the ground surface. Volvo articulated dump trucks are distinguished by excellent maneuverability and have a small turning radius.

Thanks to the articulated frame, the dump truck has a small turning radius and is able to turn around in a limited area. This increases its efficiency when performing work in small areas.

The swivel joint makes it possible to move the front and rear parts of the machine independently without breaking the frame and ensures stable contact of the wheels with the ground.

The high location of the hinge, near the center of gravity of the load, increases stability and provides high ground clearance, allowing for excellent maneuverability when working off-road and vehicle stability when moving loads at high speed.

The articulated dump truck has a relatively small size, and this allows it to be used even on public roads.

The bridge beams are designed so that they have three attachment points. Therefore, the rear wheels move independently of each other, maintaining stable grip, traction, and stability; reduces load on the frame. The frame articulation is located at the center of gravity of the load. It requires no maintenance. It is equipped with tapered roller bearings.

The good all-terrain properties of the articulated dump truck allow it to easily overcome difficult areas and perform complex tasks in any weather, at any time of the year.

The special design of the folding (down) radiator protection panel, with built-in steps, provides the driver with a service platform for servicing the vehicle. The hood can be lifted up 90 degrees, providing easy access to the engine compartment. All lubrication points and remote drainage points for operating fluids are accessible from ground level or from non-slip platforms.

Depending on operating conditions, Volvo articulated dump trucks can be equipped with all kinds of additional equipment. Thus, in some trim levels pre-start heating of the engine, diesel fuel and fuel filter is provided. The list of additional options also includes an automatic heater for the driver's cabin.

Trucks can also be equipped with a hinged tailgate, a weighing system, climate control, heated mirrors, enhanced underbody protection, high-power lighting sources and other options.

CareTrack telematics allows you to remotely monitor the vehicle’s condition (location, diesel fuel consumption, maintenance reminders, etc.).

Volvo A35F dump truck engine

The Volvo A35F truck is equipped with a D13H-A engine. This is a six-cylinder in-line diesel engine with a turbocharger and electronic control. The strengths of these engines are high torque at low speeds, fuel efficiency, serious power and throttle response, which extend the life of the power unit.

The working volume of this engine is 12.8 liters (12800 cm³). The maximum torque is 2359.1 N.m (at speeds of 1200…1400 rpm). Cylinder diameter – 131 mm, piston stroke – 158 mm. Maximum speed – 2100 rpm.

The cylinder head is monoblock, there are four valves for each cylinder, so the total number of valves is 24 pcs. The design of this engine uses individual pump injectors. The Volvo D13 engine is equipped with a modern EMS (Engine Management System) control unit. It controls all processes of diesel fuel injection into the cylinders and displays all the necessary information about the engine (engine oil level, coolant temperature, instantaneous and average fuel consumption, concentration of nitrogen oxides in the exhaust gases) on the driver’s dashboard display.

The CCV (Closed Crankcase Ventilation) crankcase ventilation system is used. It traps oil vapors in the exhaust gases under the valve cover, which contributes to better cleaning of the engine oil. Therefore, oil changes for this engine can be done at intervals of “every 100 thousand km.”

The oil pump, power steering, high-performance air compressor and fuel pump are gear driven. They are compactly located at the rear of the engine. The water pump, fan, generator and belt-driven air conditioning compressor are located at the front of the engine.

The D13H-A engine's gross power is 333.3 kW (453 hp). Its effective power is 324.4 kW (441 hp). These power figures were measured at 1900 rpm. The compression ratio (compression) is 18.1:1. To ensure that the engine achieves the standards of modern environmental requirements, an exhaust gas recirculation system (EGR - Exhaust Gas Recirculation) and SCR (exhaust gas recycling system using selective catalytic reduction technology with urea) were built into its design.

It is impossible not to mention the VEB engine brake. This is not a new thing on Volvo trucks, but its capabilities on a truck of this model are really quite serious, and this thing is certainly necessary and useful.

The engine is combined with a torque converter, which is equipped with a locking function. And also - a fully automatic adaptive gearbox. The shafts, planetary gears and bearings are reinforced to withstand the high torque generated by the large displacement motor.

The engines of F-series trucks are more environmentally friendly and also more economical than the engines of the previous E-series. This result can be considered an outstanding achievement, taking into account the fact that the power units of the E-series were already leaders in this segment in terms of diesel fuel consumption.

Prospects

CLAAS sees further changes and improvements in this market segment in the development and creation of modular structures. Each farm is unique, so it requires a “special” tractor that will perform a certain set of operations and work with a limited range of mounted and trailed implements. In order to be able to adapt each manufactured machine to the specific needs of the client, manufacturers, and even more so their suppliers, are developing large-unit assembly, unifying components, parts, systems, allowing the customer to “assemble” their tractor with such performance characteristics that optimally meet the needs of its production complex.

Volvo A35F transmission

The truck of this model is equipped with a nine-speed gearbox brand PT2519. Number of forward gears – 9; number of reverse gears – 3.

This gearbox is part of Volvo's specially designed Powertronic planetary transmission. It has a locking function that guarantees fully automatic, precise and smooth gear selection. This helps reduce driver fatigue and improve vehicle performance. Gears can be skipped when shifting if you need to accelerate faster.

Built-in transmission protection reduces the risk of driver error and increases operational safety.

Steering and brakes

To facilitate control, Volvo specialists have provided a steering system that operates on a hydromechanical principle. There are a pair of actuator cylinders that rotate the half-frames at an angle of up to 45 degrees. The designers simplified the system by removing CV joints, steering links and axles. The front wheels do not turn, which allows you to install wide-profile tires of a significant size and thereby improve the truck's maneuverability.

The steering system is designed to provide high steering force even at low engine speeds in the most challenging operating conditions. Hydraulic shock absorption prevents impacts and impacts from being transmitted to the steering wheel and the driver's hands. This system also ensures precise steering and directional stability during high-speed road driving, eliminating the need for the driver to steer.

In the loading or unloading position, the driver presses one button, which automatically applies the main brake and places the transmission in neutral. Then, the next time a gear is selected, this function is deactivated, releasing the brake.

The Volvo A25F and Volvo A30F trucks have dry disc brakes with fully hydraulic drive on all wheels. And the larger and more powerful Volvo A35F and Volvo A40F are equipped with brake discs with an oil cooling system.

As noted above, all models come standard with the Volvo Engine Brake (VEB). The retarder helps the driver control speed on downhill slopes, before turning or at intersections, preventing frequent use of the service brake system and reducing its wear.

Suspension and chassis

The car has a dependent front suspension. Structurally, it is a beam fixed to the frame part using longitudinal arms and rods. The rear axle is made one-piece and integrated with the frame via A-type trailing arms and transverse rods.

Large and wide tires maintain low specific ground pressure, excellent flotation and excellent off-road capability, providing a smooth and comfortable ride. All F Series trucks are equipped with long-lasting radial tires designed for transportation applications. They provide excellent traction and stability of the truck on the road.

This model also provides for disabling the inter-wheel differential, such as a “cam clutch”. They provide 100% blocking. The special design allows operation without slippage and wear. When the lock is turned on, all wheels rotate at the same speed, improving traction in difficult conditions.

The differential lock (ATS) can be activated and disconnected on the fly using a button on the cab floor. This is not only convenient, but also allows you to increase labor productivity and the efficiency of machine use. It prevents the articulated dump truck from constantly operating in four-wheel drive mode when traveling on good quality roads.

Constant use of all-wheel drive mode leads to increased diesel fuel consumption, wear of tires, mechanical components and transmission parts. The ATC system automatically disables rear wheel drive when it is not needed. This prevents wheel drift when turning and reduces tire wear.

And when the ATC system detects wheel slip, it engages the longitudinal differential lock and the all-wheel drive clutch. As a result, the heavy dump truck maintains optimal traction under all conditions.

F series trucks are equipped with 4 differential locks with a cam clutch: 1 – longitudinal, in the power take-off box + three – transverse, in the axles. This design solution improves traction on bad roads. The combination of these locks ensures that all wheels rotate at the same speed for improved traction under severe operating conditions. A heavy dump truck becomes easier to drive, and its performance increases.

ShSS in the vastness of the former Union

In the early 2000s, domestic automakers tried to establish production of articulated dump trucks. He became a pioneer in this direction. The company’s specialists developed two models of articulated dump trucks with a lifting capacity of 16 and 25 tons, however, this type of construction truck was never put into mass production. In 2013, the company decided to implement the idea of ​​its own production of articulated dump trucks. Soon, the S-33, a dump truck created at the site of Promtractor OJSC, rolled off the production line of the enterprise. This model is quite acceptable for domestic buyers. Perhaps construction companies are already spoiled by similar equipment from Komatsu, John Deere and Volvo. However, their cost cannot be compared with CHETRA products. In addition, according to the technical characteristics of the S-33 dump truck, a sufficient number of the most important components and assemblies of foreign manufacturing partners are installed in it. ZF axle from the German Gear Factory, Mitas tires from the Czech Republic, as well as PMC Polarteknik transmission and Eaton steering. The dump truck, with a lifting capacity of 33 tons, is equipped with a six-cylinder Cummins engine with a power of 457 hp. With. The cabin is made in accordance with ROPS/FOPS safety standards

CHETRA plans to release a new articulated dump truck (ASD) in 2016, promising, with all its advantages, one more, important thing - an affordable price. In the CIS you can also find the manufacturer ShSS. In 2001, the Mogilev Automobile Plant (Belarus) created a prototype model of such a dump truck with a load capacity of 50 tons

Unfortunately, the car was never put into mass production. It moved a little further in this regard, presenting its own development of an articulated dump truck in 2007 and even producing a small batch of unique dump trucks for trial work. However, the car did not go into mass production. Today, both MoAZ and BelAZ do not abandon their intention to establish the production of much-in-demand construction equipment. The plans of the Belarusian holding include items on the production of four models of articulated dump trucks, with a carrying capacity of 27 to 50 tons. We can only hope that all programs will be successfully implemented.
