transmission System

To which a vehicle is traveling, in addition to a motor that generates the force, are required a series of elements that transmit such movement from the motor to the wheels. The elements that are responsible for this task belong to the so-called transmission system and are the following:

  • Clutch.
  • Gearbox.
  • Trees of transmission.
  • Groups differential.
  • Bearings.
  • Bushings.

on the other hand, the transmission system can present different configurations according to the available of your drive wheels (the wheels in charge of transmitting the power from the engine to the ground). The drive wheels can be the front, rear or four, and this gives rise to different provisions.

front-Engine and rear-wheel drive

  • front-Engine, front-wheel drive.
  • front-Engine, rear-wheel drive (propulsion).
  • rear-Engine, rear-wheel drive (propulsion).
  • all-wheel drive regardless of where you are the engine.
  • mid-Engine, rear-wheel drive.

The four wheel drive can be:

  • Plug-in (only four-wheel drive when the system or the driver requires it).
  • Permanent (the vehicle is always in position 4×4).

systems all-wheel drive permanent need a device (center differential) to compensate for the difference of rotational speed occurs between the front and rear axles when you take a curve. This is the reason why the systems 4×4 plug-in can only be circular in awd up to a certain speed.
