Development of braking and steering composite driving set for electric bus

In order to use electric energy effectively,reduce mass of body as well as optimize layout reasonably and reduce cost of electric bus,the technology status of electric bus has been analyzed.And a composite driving set with air compressor and steering pump used for electric bus has been proposed i.e.one electric motor is applied to drive air compressor for pneumatic braking system and hydraulic pump for power steering simultaneously.The optimal layout of chassis technology,the active adapting control technology based on load detecting,the dynamic optimum design technology and the anti-rattle and vibration isolating technology have been used to design the composite driving set.After some tests such as energy consumption comparison,dynamic performance test as well as matching ability test for parts and reliability test for control system,the result indicates that the set is characterized with alleviating mass of complete vehicle,saving cost,reducing energy consumption and convenient arranging.
