ELECTRIC MOTOR CAR Russian patent published in 2010 - IPC B60L11/12 

FIELD: transport.

SUBSTANCE: invention relates to electrically driven vehicles and can be used in designing electric motor cars. Proposed car comprises body, chassis with suspension elements, drive and driven wheels, storage battery compartment, traction motors with reduction gears and control mechanisms. Electric motor car incorporates additionally torque amplifier, DC generator and braking rheostats. Torque amplifier comprises housing with front and rear covers. Said housing accommodates drive and driven shafts linked up by coupling linked with control rod lever. It accommodates also several amplifying elements coupled with drive shaft, each comprising rectangular-bar permanent magnet and electromagnetic linear motor, its brushes being connected to storage batteries. It houses also gear wheel fitted on drive shaft and accommodated inside round case. The latter is filled with steel balls. Torque amplifier driven shaft is coupled with DC generator shaft. Generator output is connected, via control mechanisms, with traction motors and storage batteries. Braking rheostats are connected in traction motor circuits in generation mode.

EFFECT: electric power saving, longer run between charging.
