5.4.1 The purpose of the main gear
The main purpose of the drive gear in the transmission is to transfer engine thrust to, so to speak, the "end consumer" - the wheels. Drive gear distributes traction at an angle of 90 ° between the right and left wheels. In case if the car is rear-wheel drive, then the thrust from the gearbox through the cardan drive is transmitted to the drive gear, and that, in turn, redirects the power flow to the wheels via the axle shafts (if the rear suspension is dependent and has a bridge) or drive shafts with hinges of equal angular speeds (this will be described later). In case if the car is front-wheel drive, then the drive gear is connected directly to the gearbox via a gear, and the thrust from the engine is transmitted via drive shafts with hinges of equal angular speeds.
