Planetary gearbox with integral electric motor and steering means

A new, useful and compact wheel motor drive arrangement for applications on such construction equipment as scissor lifts and other similar scaffolding equipment where hydraulically driven systems have historically been used to provide power to the wheels to move the equipment is disclosed. The invention includes an electric motor mounted to a spindle bracket which is pivotably connected to the frame of the equipment to allow the unit to be pivoted around a vertical axis for steering purposes. A gear reducing planetary gear system is mounted around the drive shaft of the motor is positioned within the rotating wheel hub. The output ring gear of the planetary gear system is integrally formed to the interior of the wheel hub so that there is a direct application through the planetary gear system to the wheel hub to provide greater efficiency.
