Passive fail safe coupling mechanism

A ground propulsion assembly (10) for an aircraft includes an axle (12), a wheel (14) rotatably connected to the axle (12), and a transmission (18). The transmission (18) includes a housing (28) mounted proximate the axle (12) and a drive element (22) disposed at least partially outside of the housi...

More Information
Summary:A ground propulsion assembly (10) for an aircraft includes an axle (12), a wheel (14) rotatably connected to the axle (12), and a transmission (18). The transmission (18) includes a housing (28) mounted proximate the axle (12) and a drive element (22) disposed at least partially outside of the housing and operatively connected to a power input. A disengagement spring (24) is disposed between the transmission (18) and the axle (12) and the disengagement spring (24) is configured to urge the drive element (22) out of engagement with the wheel (14). An actuator (26) is operatively connected between the transmission (18) and the axle (12), the actuator (26) being configured to selectively generate a force in opposition to the disengagement spring (24) such that the drive element (22) moves relative the wheel (14) and operatively engages the wheel (14) to transfer torque to the wheel (14).
