TRW is never happy to rest on past laurels, which is why we took our commercial vehicle steering and suspension products to be tested in Germany by the FRAUNHOFER-INSTITUT independent test center. Among the TRW parts that stood out from the crowd were the radius rods, tie rods and V-Links. Competing against six other industry leaders, these TRW products excelled, receiving top marks for durability, strength and performance. These tough tests highlighted that TRW products have the ability to perform better for longer under extreme pressure. This industry recognition is evidence that the TRW products can deliver real safety without compromise.

The results were testimony to TRW’s own testing policies, which serve to place the parts in extreme conditions that many drivers will never encounter. This means commercial vehicle drivers can have peace of mind that wherever they travel, because they can trust the TRW parts.

With your customers’ margins increasingly being squeezed and time being money, the need for high quality parts that reduce the amount of time spent off the road is critical. By giving them TRW over cheaper, lesser quality options, you will improve the performance of your customers’ commercial vehicles and save businesses money.

The TRW tie rod end features an exceptionally innovative design that is smaller, stronger and longer-lasting than ever before.

Through TRW we can provide tailored solutions for drivers that cover a huge number of parts, and with independent experts placing us above other competitors, choosing TRW guarantees the very highest quality. Steering gears are employed to attach the steering wheel with the steering linkage of a vehicle. This is clearly a crucial part for the overall performance of a commercial vehicle, and steering gears that are faulty or worn out could be seriously dangerous for drivers. TRW parts will act to lengthen vehicle life, helping businesses to save time and therefore money in the long run with their trucks, buses or vans staying on the road for longer.

TRW was responsible for developing and producing the first boxed, OE-quality steering gears program to the aftermarket. Our current catalog of parts includes 33 TRW designed TAS and THP type gears:

• TRW TAS type steering gear – These are created with the fewest possible moving parts to ensure superior torque output and performance. They are ideal for vehicles on and off the highway that have medium and heavy front axle loads, helping to improve handling and steering control.
• TRW THP type steering gear – These gears are designed to provide a faster steering ratio that improves the lock-to-lock turns and return-to-center response. With an optional, innovative Positive Center Feel feature, drivers will also get an enhanced steering gear on-center feel without having to increase the steering park effort.

All TRW parts are produced to the very highest standards that we set ourselves, and as a result they often exceed the industry-approved regulations. At our center of excellence in Frydlant, Czech Republic, all parts are tested to the extreme using the following measures:

• Acoustic testing to ensure driver comfort
• Strength testing to help maximize durability
• Environmental resistance to ensure optimum ability for all weather conditions
• Drive tests for wear
• Safety features examined using assembly technique testing
• Leak-free performance dynamic testing
• On-road testing at TRW tracks

We also take our commercial vehicle steering and suspension parts to be tested independently, and in 2014 TRW parts went under the microscope at the renowned FRAUNHOFER-INSTITUT for Structural Durability and System Reliability. The outcome of these tests highlighted the exceptional performance of TRW parts, which outperformed six leading competitors, highlighting our ability to deliver real safety without compromise. With top marks for durability, strength and performance it is clear that choosing TRW ensures that you get the quality you need to help minimize vehicle downtime in the commercial industry.

Europe is a global leader in the commercial vehicle market and in May 2014, the number of van, bus and coach registrations grew, with the overall number of commercial vehicles increasing by a huge 10.8%. This highlights the unique opportunities that lie within this market, where choosing TRW means that you can deliver parts that will make a real difference on the road to businesses.

As operator costs increase year on year, it is becoming more and more important for business owners to keep their vehicles on the road for longer, as anytime off the road is time and money wasted. Opting for TRW steering gears will help you to provide your customers with a more viable economic option.

ACEA (the Association of European Automotive Manufacturers) has also noted that all commercial vehicles should be repaired with original spare parts or parts of matching quality, and TRW takes great pride in being able to offer this quality with all of our steering gear parts. We will remanufacture steering gears using TRW OE quality components that deliver exactly the same standards as new OE products.

• The very latest steering technology
• The smallest and lightest component of its kind on the market delivering a more efficient performance

As the heavyweight in safety, TRW can provide a huge choice of parts covering steering, suspension, brake pads, shock absorbers and more. Our new XCAP tie rod end is one of the most advanced vehicle parts ever produced.

Carefully designed, the XCAP has been tested to the extreme, providing you with peace of mind that it is a part that will not let drivers down. As a smaller, stronger and more durable product than previous ball joints, it will have a longer life and more efficient all round performance.

An enhanced cover also gives the XCAP ball joint excellent protection from wear and tear, while the reduced torque means improved steering comfort and smoother journeys for all. The overall result is that steering and suspension in commercial vehicles is boosted, making the XCAP a valuable addition to the steering and suspension range for you and your customers.

The parts on commercial vehicles experience extreme pressure owing to the huge amount of weight that they have to carry. Most commercial vehicles already have a heavy chassis and when you add on the weight of the load it is important that the component weight is as low as possible, otherwise the kinetic energy of the vehicle could be affected.

If this does happen then driver and load safety could be compromised. Unseen forces are placed on the parts every time the brakes and steering systems are used, which makes it critical that they stand up to the rigors of daily life. TRW tests all parts thoroughly to ensure they have the ability to perform at their best for longer.

When tested against leading competitors, the XCAP performed much better across a range of durability, performance and strength tests that were carried out by the FRAUNHOFER-INSTITUT in Germany for Structural Durability and System Reliability. Compared against six other market leaders, the TRW XCAP Ball Joints lasted up to four times longer than any others. While competitors showed signs of damage such as worn bearings, cone issues, dust cover faults and nut errors, the tests had no effect on the XCAP.

To achieve such impressive results from independent testing, we have to perform extreme examinations ourselves before we send any parts to market. With the XCAP tie rod ends this is especially important because we are the only manufacturer producing such a part. Our tests include:

• Assembly technique testing of all critical safety features
• Environmental resistance for all weather conditions
• Wear and drive tests
• Extensive road testing on TRW tracks across the world
• Acoustic measuring to help enhance driver experience

All of these tests fall in line with OE checks, which give you peace of mind that all TRW products will be as good as, and often better, than everything else available on the market.

You only need to look at our list of partners to see how we’re trusted in the industry. We’ve signed contracts with Daimler Trucks, Scania and Volvo Trucks that allows us to cover a wide part of Europe and South America.

With a large Original Equipment market share on tie rod ends as well as drag links and other important steering and suspension parts for commercial vehicles, it’s TRW that you can trust when it comes to robust, high-quality CV parts.
