Abstract
A drive assembly for a vehicle may selectively couple a motor of the vehicle to a mobility assembly of the vehicle. The drive assembly may include a worm gear assembly having a worm engaged with a worm gear. The worm may be operably coupled to the motor of the vehicle, and the worm gear may be selectively coupled to a shaft of the mobility assembly. The drive assembly may be configured to move between a first configuration and a second configuration. In response to the drive assembly being in the first configuration, the worm gear assembly and the shaft of the mobility assembly may be operably coupled, and the worm gear assembly may be configured to selectively transfer power from the motor to the mobility assembly to provide mobility to the vehicle. In response to the drive assembly being in a second configuration, the worm gear assembly and the shaft of the mobility assembly may be decoupled, and the worm gear assembly may be prevented from transferring the power from the motor to the mobility assembly.
