Balancing device for balancing inertia force torque of crankshaft of three cylinder engine, of motor vehicle, has toothed wheels whose axes are coplanar with axis of crankshaft, where two masses are assembled on corresponding wheels

摘要

The device has balancing masses (M1, M2) located at ends of a crankshaft (1). The masses are assembled on corresponding teeth e.g. helical and straight teeth, wheels (R1, R2) driven by the crankshaft with rotational speed. Two axes (X1, X2) of the toothed wheels are coplanar with an axis (X) of the crankshaft. Each toothed wheel is driven by a pinion (P1) i.e. drive pinion. The pinion rotatably drives an accessory of the engine, where the accessory is selected from one of oil pump, injection pump, water pump, vacuum pump, alternator or air-conditioning compressor.
