An electric drive machine includes an axle assembly having a central axle housing. An electric drive motor, having a motor housing, is oriented along an axis and disposed within the central axle housing. An air cooling system includes a blower fluidly connected to and positioned upstream of an opening of the central axle housing. An airflow path through the central axle housing includes an upstream segment and a downstream segment. The upstream segment extends from the opening to an airflow deflector, and is configured for airflow in a first direction along an axial path. The downstream segment extends from the airflow deflector to the motor housing, and is configured for airflow in a second direction, which is opposite the first direction, along a helical path.

The present disclosure is directed to a protection system for a vehicle cab. The protection system includes a first structure and a second structure. The first structure is disposed between a floor of the vehicle cab and a vehicle tire. The second structure of the protection system is disposed between the first structure and the cab floor. Further, the second structure includes a non-metallic laminate and an air gap disposed between the first structure and the second structure.

An electric drive machine includes an internal combustion engine remotely coupled to an electrical power generator, which is electrically connected to an electrical components system. The electrical components system is electrically connected to a pair of electric drive motors that are configured to drive wheels of the electric drive machine. A cooling system includes a blower fluidly connected to, and positioned downstream of, the electrical components system. The blower is fluidly connected to, and positioned upstream of, the electrical power generator and the pair of electric drive motors.
