1. A transmission for an at least partially electrically driven vehicle, comprising an input shaft which can be coupled to a rotor shaft of an electric machine via a synchronization device; at least one friction disk which is located axially between a first synchronization ring, which is connected to the rotor shaft for conjoint rotation, and a second synchronization ring; a clutch body which is connected to the input shaft for conjoint rotation; and a sliding sleeve which is axially slidable along the clutch body, wherein:
the sliding sleeve is designed to be moved axially in relation to the clutch body by an actuating element in order to initiate synchronization of the two synchronization rings and establish a connection to the two synchronization rings for conjoint rotation in order to couple the rotor shaft to the input shaft;
the input shaft is mounted coaxially to the rotor shaft by means of a first bearing element;
the rotor shaft is supported radially relative to a housing of the transmission by means of a second bearing element;
the rotor shaft is designed to be hollow at least in sections at an end facing the input shaft in order to receive the first bearing element for mounting the input shaft; and
the first bearing element is disposed at least partially radially inside of and axially overlapping the second bearing element.
