A drive assembly for a mining vehicle includes a frame, a housing coupled to the frame, and a motor positioned in the housing. The motor includes a motor frame with a first axial end and a second axial end opposite the first axial end. The drive assembly also includes a transmission that is positioned at least partially within the frame. The transmission is coupled to the motor frame at the first axial end. The drive assembly further includes a support assembly that couples the second axial end of the motor frame to the housing.

A vehicle drivetrain for a vehicle including a transmission configured to move the vehicle with a surface engaging traction member and a final drive assembly configured to drive the surface engaging traction member. The final drive assembly includes a drive assembly coupler. A transmission coupler is operatively connected to the transmission and disposed between the transmission and the drive assembly coupler. The transmission coupler includes a first position engaged with the drive assembly coupler and a second position disengaged from the drive assembly coupler. An actuator is operatively connected to the transmission coupler and is configured to move the transmission coupler between the first position and the second position. The actuator, in one embodiment, includes a worm drive having a worm gear configured to move the transmission coupler along a longitudinal direction of the transmission. The worm gear rotates about an axis inclined with the longitudinal direction.

A drive sprocket assembly is provided. The drive sprocket assembly includes at least one first segment and at least one second segment. Each of the at least one first segment and the at least one second segment is adapted to be removably affixed to a hub of the drive sprocket assembly. Each of the at least one first segment and the at least one second segment includes a top surface and an inner surface extending away from the top surface. The inner surface includes a stepped configuration. The inner surface is adapted to at least partially abut a raised portion of the hub and an outer surface of the hub. The drive sprocket assembly also includes a tooth segment provided on the top surface of each of the at least one first segment and the at least one second segment respectively.

A crawler track includes a link and is driven in a direction of travel by a sprocket having a plurality of teeth. The link includes a pad, a first grouser, and a second grouser. The pad defines a first surface, a second surface opposite the first surface, a first end, and a second end spaced apart from the first end along the direction of travel. The pad defines at least one opening extending through the pad between the first surface and the second surface, and the opening is operable to receive a sprocket tooth. The first grouser is positioned on the first surface proximate the first end of the pad, while the second grouser is positioned on the first surface proximate the second end of the pad. The first grouser and the second grouser extend in a direction substantially perpendicular to the direction of travel of the track.
