Commercial vehicles are to benefit from a new range of heavy duty (HD) alternators and starters, two of the latest technological advancements by Bosch which will provide end-users principally with a higher level of durability, greater efficiency and cost reduction.
With the latest innovation, a complete range for 14 or 28 volt-HD specification alternators will now be available for commercial vehicles. Modular construction enables a flexible approach to meeting the needs of customers, and the range also provides the incremental enhancement of service life, efficiency and temperature resistance.
By improving the geometry of the stator and raising the proportion of copper fill, this has raised maximum efficiency from 70 to 76 percent, thereby augmenting alternator output and fuel consumption by up to 0.5 litres per 100 kilometres. The new components which feature larger ball bearings and reinforced end plates, have added cost advantages resulting from the need for no servicing, coupled with an extended life of service to up to 800,000 kilometres. Heat-resistant ball bearings may be fitted to the alternators in applications where thermal stress and temperatures reach up to 180 degrees Celsius. High belt tension placed on the alternator is equally addressed with the option of reinforced ball bearings and greater cooling.
With a principal focus on the 12 volt segment, the latest heavy duty starters in the HX(F) 95 range will equally bring added benefits to users commercial vehicles with a diesel engine displacement of up to 13 litres, and a starter power requirement of between 2.4 to 6.5 kilowatts. The exchange of the six pole wave winding for a four-pole loop, and a modification to the design of both the armature and pole housing, will provide increased power and greater starting reliability which will be most significant for the higher-capacity powerplants.
A more robust and durable construction used for the new starters will also promote reduction in costs resulting from greater protection from factors such as vibration, dirt and moisture, but more importantly, from a longer service life which, like the alternators, now extends to 800,000 kilometres on the road or to 14,000 hours of off-road use. More compact dimensions than previous versions will enable increased flexibility in the assembly and design processes of vehicle manufacturers.
