Countershafts

Shafts in a gearbox that carry gears, transferring motion from the input shaft to the output shaft, enabling gear ratio changes.

Inertia Brake

An Inertia Brake is a type of brake system that utilizes the inertia of the vehicle or component (usually in trailers) for activation, providing additional braking force especially during deceleration or when going downhill.

Clutch Brake

Circular disc with friction surfaces on both sides mounted on the transmission input shaft; its purpose is to slow or stop the input shaft during initial shifts to prevent gear clash.
