Mass compensation module for internal combustion engine, has oil and vacuum pumps arranged within housing of module, and motor/generator and pump shafts driving electrical generator, which is separated from crankshaft over coupling

摘要

The module has a housing fastened at a crank case. A crankshaft (1), a compensation shaft (9), a motor/generator shaft (6) and a pump shaft (12) are provided for driving an oil pump (4) and a vacuum pump (5) over a drive system (2). The pumps are arranged within the housing of the module. The motor/generator and pump shafts drive an electrical generator (3). The electrical generator serves as a motor for the motor/generator and pump shafts. The electrical generator is separated from the crankshaft over a coupling (14). The generator drives the pumps after decoupling the drive system.
