EvoBus equips new vehicles with lightweight air springs01 October 2019

Bus manufacturer EvoBus is equipping its buses with a lightweight air spring system, which uses plastic components instead of steel or aluminium – saving 15kg on a two-axle urban bus.

The air spring system, from Continental, uses an integrated roller piston made from polyamide, saving between 2-2.6kg per air spring module, depending on the axle type of the vehicle.

Continental says the system delivers “outstanding ride comfort”, while helping to offset the extra weight of exhaust gas aftertreatment systems in Euro VI vehicles. It is also ideal, says the company, for use in electric vehicles to counter the additional weight of batteries.

Diethelm Bauch, head of air spring systems in Continental’s commercial vehicles original equipment division, says: “Our lightweight air springs have, in one fell swoop, given bus and commercial vehicle manufacturers a solution that offers much greater design flexibility. Plastic offers much greater design freedom and the capacity for customised, comfort-oriented design.”
