Power unit for a motor vehicle

摘要

#CMT# #/CMT# An engine (1) includes an IC engine unit (2) and a transmission (3) with a hydrostatic device (6) leading to a drive shaft (4). The hydrostatic device, including a displacement volume adjustable hydraulic pump (12) and an intake volume adjustable hydraulic motor (13), cooperates with the engine unit to transfer torque from the engine unit to the drive shaft. A spur gearing (7) is interposed between the engine and the hydrostatic device. #CMT# : #/CMT# An independent claim is also included for a method to operate an engine in a motorcycle. #CMT#USE : #/CMT# Engine for motor vehicle e.g. motorcycle of one- or multi-track and or light- or heavy-type. Can also be used in on- and off-road vehicles. #CMT#ADVANTAGE : #/CMT# Engine of simple design can be optimized with regard to its construction and function, since hydrostatic device of transmission cooperates with engine unit and is in effective connection to planetary transmission. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the schematic diagram of an engine for a motorcycle. 1 : Engine 2 : IC engine unit 3 : Transmission 4 : Drive shaft 6 : Hydrostatic device 7 : Spur gearing 12 : Hydraulic pump 13 : Hydraulic motor.
