Device for Transmitting a Torque in a Range Extender

Abstract

A device for transmitting a torque between an internal combustion engine and a generator has a motor-side shaft, a generator-side shaft, a separate transmission element for transmitting the torque between the two shafts, and a seal device. The motor-side shaft and the generator-side shaft are situated in each case substantially coaxially with respect to one another and are in each case connected by way of a shaft-hub connection to the transmission element, wherein a lubricant chamber which is situated radially outside the transmission element and between the motor-side shaft and the generator-side shaft and which couples the two shaft-hub connections with regard to a flow of lubricant is sealed off with respect to the outside by the seal device.
