Abstract
A drive system for an electric motor vehicle, including a differential gear device including an input element connected to an electric motor and two output elements from which the motor power received by the input element is distributed to a first wheel drive member and an intermediate shaft which extends through a hollow output shaft of the motor and is connected to a second wheel drive member, wherein the first drive member and intermediate shaft have splined end portions which engage splined center bores of the two output elements of the differential gear device, and a stop member is provided on one of the two output members, so as to protrude into at least one of the first and second center bores, such that the end faces of the end portions of the first drive member and intermediate shafts are abuttable on the opposite ends of the stop member, whereby a transverse thrust force applied to the drive members is received by the stop member.
