TRW exchange parts programme exceeds expectations

TRW has revealed that due to increased steering efficiency properties, sales of its remanufactured column drive programme of exchange parts have exceeded expectation; and as a direct result the business has achieved the position of market leader across the European aftermarket.

Compared to a belt driven hydraulic power steering pump, TRW’s Electrically Powered Steering (EPS) column drive is extremely efficient; using only 10 per cent of the energy of the afore mentioned and only when the driver demands it.

The column drive unit uses an innovative torque sensor that comprises an inductive modular design, providing class-leading vehicle dynamics. Designed initially for the small-car segment, TRW’s EPS column drive offers a modular and scalable design which reduces or eliminates many design compromises long accepted in steering systems; it provides premium performance, resulting in a safer and less fatiguing driving experience.

In addition, significant fuel economy and CO2 emissions benefits can be realized when compared with traditional hydraulic power steering. The technology can deliver a fuel saving of 0.3 to 0.4 L/100km, with a corresponding reduction in carbon dioxide emissions of approximately 7-8g/km.

This programme is the first in a series of remanufactured EPS product launches by TRW; with the business set to launch a remanufactured EPS steering gear programme in 2014.

The exchange references are produced to the same standards and carry the same two year warranty as new parts. All seals and broken or worn components are discarded and replaced with new parts. Assembly is carried out to OE factory specifications using OE quality components and 100 per cent of the units produced are tested to TRW’s performance specifications with, the end of line tests including noise, performance and function.
