This directory contains documentation for every modular powertrain device available in the vehicle Lua context. These components are used to build complex power delivery systems from the engine to the wheels.

Core Components

  • Powertrain Base Device: Inherited methods (:lockUp(), :setExternalTorque()) and properties.
  • Combustion Engine: Standard internal combustion engines with torque curves and thermals.
  • Electric Motor: High-torque electric propulsion systems.
  • Differential: Splits power between outputs, supporting open, locked, LSD, and active types.
  • Shaft: Simple rotational connection between components (e.g., driveshafts, axles).

Gearboxes and Clutches

  • Manual Gearbox: Traditional H-pattern or sequential manual transmissions.
  • Automatic Gearbox: Torque-converter based automatic transmissions with planetaries.
  • DCT Gearbox: Dual-Clutch Transmissions for rapid shifting.
  • CVT Gearbox: Continuously Variable Transmissions.
  • Friction Clutch: Standard mechanical clutches.
  • Torque Converter: Fluid coupling for automatic transmissions.

Forced Induction

  • Turbocharger: Exhaust-driven air compressors.
  • Supercharger: Engine-driven air compressors.
  • Nitrous Oxide Injection: Chemical boost for combustion engines.

Auxiliary and Specialized

  • Thermals: Advanced cooling and heat management for engines.
  • Hydraulic Components: Pumps, cylinders, and accumulators for hydraulic systems.
  • Electric Winch / Servo: Specialized electric actuators.
  • Range Box: Transfer cases for low/high range 4WD systems.

Electric Winch

Electrically-driven winch device for pulling operations. Provides controlled cable spooling with configurable line speed and pull force limits.

Friction Clutch

Standard mechanical friction clutch operated by the clutch pedal. Provides progressive engagement between the engine and transmission through friction plate contact.
