(EPS timing belt, EPS steering system)

Hannover, February 2009. BMW, ZF Steering and ContiTech have developed an Electro-Mechanical Power Steering (EPS) with Axial Parallel Layout (APA), which has been used successfully in the BMW 1 and BMW 3 series since 2006, and is therefore Has proven itself in production applications. The system makes an important contribution to environmental protection and optimal driving comfort, as it reduces energy consumption and thus CO2 emissions and requires only minimal steering effort. ContiTech has developed the helical toothed belt CONTI SLT POWER for the timing belt drive of electric power steering.

The electromechanical steering systems of BMW, ZF Steering and ContiTech mainly consist of electric motors, recirculating ball screw spindles and timing belt drives. Compared to the hydraulic version, this type of electromechanical servo system does not require energy when driving in a straight line, thus significantly reducing fuel consumption - up to 0.3 liters per 100 kilometers. It also significantly reduces carbon dioxide emissions. In addition, EPS-APA optimizes driver comfort, as very high forces of up to 13 kN are generated with minimal steering force via the recirculating ball screw spindle on the draw rod. In addition, the steering force can be adjusted to be speed-dependent and progressive by means of suitable software. Another environmentally relevant benefit of EPS-APA is that the system does not require hydraulic oil. Due to the modular structure of the EPS system, it can be easily used in different types of vehicles.

High demands are placed on the timing belt drive of the EPS steering system. Compared to belts operating in an engine environment, belts in steering gear must be able to withstand very low temperatures just above the road surface. It is for this reason that ContiTech Power Transmission has developed the CONTI SLT POWER timing belt. SLT stands for "Extra Low Temperature" as the belt is designed for a temperature range of -40°C to +120°C. “In testing, even peak readings at -45°C and +130°C. This advancement was achieved by using a special EPDM low temperature elastomer that is highly resistant to ageing, cold and heat resistance,” explains Hermann Schulte, R&D Manager at ContiTech Power Transmission Group. Integral fiberglass cords also provide belts with exceptionally high fatigue strength, water resistance and dimensional stability under reverse bending stress.

The comfort benefits of particularly low noise levels also played an important role in the development of BMW, ZF Steering and ContiTech. The sprocket and belt profiles have been specially developed for this application and feature a 5-degree helix angle, ensuring trouble-free tooth engagement and optimized acoustics. To ensure that no belts generate noise levels higher than 45 decibels, each belt is acoustically tested before delivery. "It's a book that's commonly found in ordinary libraries," Schulte compares. During production, each belt has an individual identification mark to ensure the uninterrupted product traceability required by the steering system. The timing belt drive offers a high degree of overload protection: under extreme loads, the belt can jump without damage. The high quality of the product enables the maintenance-free life of the entire steering system to exceed 15 years.

ContiTech has developed the helical toothed belt, CONTI SLT POWER, for the timing belt drive of BMW, ZF steering systems and ContiTech's electromechanical steering systems.
