Vehicle transmissions, are mechanical systems that transmit and adjust torque and speed between the drive motor and the drive wheels. They facilitate the efficient transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. of power in changing driving conditions. In wheeled vehicles, particularly tracked ones, transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. systems often fulfil additional functions. These include steering via differential speed on the two sides, integrated braking mechanisms, reverse gear, and in some cases, suspension Suspension Systems Suspension systems are designed to dampen the shocks and vibrations experienced when driving on uneven terrain. and energy distribution. Depending on the design, transmissions can be controlled manually, automatically, hydrostatically or electrically. In heavy-duty applications, such as in commercial vehicles or military technology, they must also be compact, robust and easy to maintain.
