gearset

Coupling opposing sets of counter rotating weights with a gearset, the proprietary eccentric weight vibrators either add together or cancel the reactive centrifugal force based on the angular position of the weights.

The new system is based on the electronically controlled Continuously Variable Planetary (CVP) transmission of Lexus Hybrid Synergy Drive, coupled with an all-new four-speed automatic gearset at the output stage.

It is to be equipped with a 90-bhp electric motor and a 105-hp 1.8-litre four-cylinder with planetary gearset CVT, which consumes 2.5L per 100km.

The target of the ire, a reader reports, was a poster found at bus stations with a colourful gearset that supposedly acted as a indicator of how the Metro helps "make the city work together".

However, power is shared and drives the wheels through a planetary gearset that can allow either power source to provide 0% to 100% of the vehicle's power need.

Figure 1 shows a powersplit HEV configuration that includes two electric motors coupled to the engine through a planetary gearset and to the wheels through the driveline.

The engines feature geared turbofan technology, which adds a planetary gearset between the engine's fan and LP shaft in an effort to boost efficiency by running the turbine/compressors at a different (slower) speed that the fan.
