Abstract

A transmission device (3) of a vehicle for distributing a driving torque of a transmission input shaft (13) to at least two transverse vehicle shafts (4; 4X; 4Y; 4Z; 5). Between the transmission input shaft (13) and a transmission output shaft (15) gear elements (16 to 25) are disposed in a housing (11) for the purpose of implementing different gear ratios. One of the vehicle axles (4; 4X; 4Y; 4Z) extends through an inner space (10) of the housing (11). In a cross-sectional area disposed perpendicular to the longitudinal axis of the transmission device (3), in which area the transverse vehicle shaft (4; 4X; 4Y; 4Z) that is guided through the housing (11) is disposed, at least part of an electrical device (45, 46), which is mounted to the housing side, and/or at least part of a temperature control unit (47), which is mounted to the housing side, are provided.
