Electrical propulsion unit for car, has crankshaft drive mechanism connected to unit holder and crank by couplings which are moved towards each other or apart in order to turn crankshaft

摘要

#CMT# #/CMT# The unit comprises a holder such as a motor block, a crank (11) with a crankshaft (6) rotatably connected to the holder and a crankshaft drive mechanism. This mechanism is connected to the holder via a first coupling and to the crank via a second coupling and is designed to move the two couplings towards and/or away from each other in order to turn the crankshaft. The drive mechanism is formed by a hydraulic or pneumatic jack with a drive shaft (5) which can be moved up and down inside the jack casing (4) by an electric motor (3). #CMT#USE : #/CMT# For driving the gearbox of a car. #CMT#ADVANTAGE : #/CMT# None given. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the propulsion unit. 3 : electric motor 4 : hydraulic jack casing 5 : drive shaft 6 : crankshaft 11 : crank.
