Series and parallel hybrid drive with two primary drive units

摘要

#CMT# #/CMT# The train (1) has two primary units (2, 4) and a hydraulic or electric machine (6). The hydraulic or electric machine and the primary unit (2) are operatively connected to a drive shaft (8). The hydraulic or electric machine forms a serial hybrid drive with the primary unit (2) and forms a parallel hybrid drive with the primary unit (4). The primary units have different sizes regarding the power output. The large primary unit (2) is an internal combustion engine. The small primary unit (4) is a free-piston engine. #CMT#USE : #/CMT# Hybrid drive train for a vehicle. #CMT#ADVANTAGE : #/CMT# The fuel consumption and carbon dioxide emission are reduced, so that the efficiency of the hybrid drive train is increased. The hybrid drive is variably applicable. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a hybrid drive train. 1 : Hybrid drive train 2, 4 : Primary units 6 : Hydraulic or electric machine 8 : Drive shaft 20 : High pressure line 24 : Low-pressure line.
