Abstract

A bearing system for an engine-transmission (motor-transmission) unit transversely installed in a vehicle body of a motor vehicle, includes a first bearing element positioned between the engine and the vehicle body, a second bearing element positioned between the engine or the transmission and the vehicle body, and a third bearing element positioned between the transmission and the vehicle body. The second bearing element is formed and positioned without a movable intermediate element at the engine or transmission and vehicle body so that torque forces of the engine-transmission unit, supported by the second bearing element, are introduced into the vehicle body substantially in the vehicle longitudinal direction and so that the second bearing element, in a first domain, which includes small excursions in the vehicle longitudinal direction about the static position of rest at standstill of the engine has a first spring rate, and in a second domain, which adjoins the first domain, and includes larger excursions in the vehicle longitudinal direction, has a second spring rate. The second spring rate is greater than the first spring rate.
