products

Rába has successfully integrated its products into the value chain of the global commercial vehicle industry. It supplies axles, spare parts and various structural components to major players in the automotive industry, and special components and chassis to heavy equipment manufacturers in the construction industry. As international customers work along global sourcing strategies, Rába has to develop and produce competitive products in this global supplier competition. Accordingly, Rába offers a full range of product-related services and provides complete industrial solutions for complex customer requirements: engineering services, development, testing, prototyping and series production

Axles

Rába’s primary product is the axle, which is supplied to the world’s major commercial vehicle manufacturers.

It produces mainly for export, with the United States traditionally its largest market and a growing presence in Western Europe and the CIS region. Rába is present on its markets with complete axles and large-series axles and transmission parts, manufactured in medium and small series. Complete axles can be divided into the following product groups according to their application:
• high-performance agricultural machinery axles,
• truck axles – driven, steered front and driven rear
• bus and trolleybus axles – single- and double-stage and low-back.

Special axles developed specifically for bus applications are successful products of Rába in the domestic, Russian and Japanese markets. In a highly successful development partnership, the company has also been supplying axles for ISUZU low-floor buses and medium-duty trucks in Japan for more than a decade, for use in the cities of Japan. Rába axles have also been successfully proven in military applications. To date, the company has supplied special axles for more than 4,000 Cougar vehicles for the US Army and for UN peacekeeping vehicles.

AxLE COmponents

Rába has unique experience in the production of forged products, and thanks to continuous development, the largest modern forge in Hungary and a modern heat treatment equipment with the capacity to match, is located in Rába. As a result, in addition to the development and production of complete axles, Rába’s main profile is the production of forged parts for the automotive industry (trucks, buses and special vehicles). These are incorporated into products from the world’s global vehicle manufacturers, in addition to its own axles.

In addition to forging, the technology also includes heat treatment, isothermal annealing and normalising of forgings, as well as refining, straightening, crack detection, grain mixing and surface cleaning of forgings, and hardness measurement.

The product range:

  • Assembled units and machined castings 
  • Head assemblies
  • Housings, I-Beams
  • Conventional and integrated articulators
  • Beams I-Beams, semi-beams, brake keys)
  • Spherical and symmetrical forgings (ring gears, driving cone gears, crown gears, planetary gears, planetary carriers, hub gears, axle shafts, flange gearbox halves)
  • Arms (arm-tie rods, steering arms, brake arms, cardan forks, spider differential)
  • Supports and consoles (brake consoles)

Chassis, welded structures

In order to make economical use of the cold-forming capabilities that Rába has built up over the past decades and our production capacities, we manufacture large complete painted sub-assemblies and semi-finished products for our customers who produce complete heavy construction vehicles in a continuous operation:

  • Vehicle frame structures, chassis and other welded structural components
  • Vehicle bodies, vehicle accessories, assembled units and parts

 The buyers are major European manufacturers of military vehicles and earthmoving equipment.

Gearboxes

Rekard, a member of the Rába Group, develops and manufactures universal and special axles for agricultural machinery, which allow straight and angular drives with various gear ratios. The carrier diff sub assembly is usually made of cast, but in smaller series production the carrier diff sub assembly is welded from steel plate. For gears we use mainly 20MnCr5, 16MnCr5 forged steel with case hardening, for shafts we use, depending on the stress, heat treatable steels (e.g. 42CrMo4), with inductive hardening on the wear surfaces.

The unified universal angle drive family offers a wide range of applications with a variety of gear ratios, drive directions and coupling sizes across 9 power ranges.

Vehicle industry parts

Rába manufactures and supplies automotive components – especially commercial vehicle axles, passenger car and engine area parts – partly for its own products, but also for European industrial companies in the commercial and passenger car manufacturing industry. The assembled, mounted spare parts are incorporated into axles and brake assemblies.

With its pressed, welded and various machined parts, Rába is a recognised supply partner for the automotive industry in the Central European region, selling its products to international automotive companies. The product portfolio consists of thousands of different structural components and parts. (V-belt pulleys, rings, housing-type parts, ball pivots, axles, axle stubs, brake discs, spider differential, arm-tie rod, coupling brackets, belt pulleys, planetary gears and other connecting parts.)

Technical services

Development services

Rába – in cooperation with its partners – offers a wide range of services, undertakes the development of new products and product families, from the concept through sample production to the performance of the necessary tests, and the implementation and monitoring of any technical changes that arise during the product’s life. During the introduction of a new product, the number of development iterations can be significantly reduced by using modern simulation tools, combined with Rába’s rich product development experience. In the offer of technical services, Rába’s design, project and test engineers – in accordance with international practice – cover the entire development process. Their activities include bearing and gear sizing, lifetime calculations, project management with key customer and supplier relationships, 3D design, finite element simulations, strength sizing, frequency and order analysis, and validation of undercarriages for full physical , through bench test capacity.

Testing services

Based on its decades-long market presence, Rába has built a test knowledge and infrastructure that is a key factor in the introduction of a new product, complementing the use of modern simulation tools. Combined with Rába’s rich product development experience, the number of development iterations can be significantly reduced. The conformity of the product, the basis of the final approval, must always be based on some kind of physical examination, as these are critical parts from the point of view of safety of life and property. Undercarriages and undercarriage components under development must be tested on a test bench, checking the quality of the design, sizing and manufacturing process and its effects on the product life cycle. At the Rába test center, all tests that arise during the development process in the case of complete undercarriages can be performed. Rába performs a total of twenty-seven internal company standard test procedures, including fatigue life and drive chain life tests, noise measurements, brake tests, oiling and climate tests.
