INFINITELY VARIABLE TRANSMISSION COMPARED TO PRESENT USED AUTOMATIC TRANSMISSIONS OF CITY BUSES
STUFENLOS WIRKENDES HYDROSTATISCHES LASTSCHALTGETRIEBE IM VERGLEICH ZU BEKANNTEN GETRIEBEN IM STADTBUSEINSATZ UNTER BERUECKSICHTIGUNG VON BREMSENERGIERUECKGEWINNUNG
Within the reported work the concept and the design feature of new drives for city buses are explained using an infinitely variable transmission and mechanical or hydraulic systems to recover the brake energy. The system components are described. Furthermore the kind of influence of the bus operation with regard to the economy of the brake energy accumulator is explained. These alternative drives are compared to present used automatic transmissions with torque converter and change speed gears, as far as fuel consumption, pollution and drive performance are concerned. This comparison includes different automatic transmissions with a large hydrodynamic convertor range and less mechanical speeds on one side and a minor hydrodynamic convertor range and several mechanical speeds on the other side. The systems with brake energy recovery allow an average fuel reduction of 30%. From today's point of view the higher purchase costs of the infinitely variable transmission and the accumulator are armortized within three years.
