Electric vehicle i.e. tractor, has drawbar detachably securing driven trailer at trailer coupling of vehicle, and electric machines designed as wheel drives, where trailer comprises combustion engine independent drive for vehicle

摘要

The vehicle (1) has a drawbar (5) detachably securing a driven trailer (2) at a trailer coupling (6) of the vehicle, where drive torque of the trailer is controlled based on bending angles (alpha, beta) between intersecting longitudinal axes (9, 10) of the vehicle during driving the vehicle along curves. The trailer comprises a combustion engine independent drive (7) for the vehicle, where the drive is coupled with a drive axle (8) of the trailer through gear boxes. The vehicle comprises two electric machines (3) that are designed as individual wheel drives with differential gears. An independent claim is also included for a method for controlling moment of an electric car.
