Allied Motion Technologies introduces the WheelMaxTM Steering Series wheel drive assemblies. WheelMax Steering Drives are fully-integrated, electrically-powered traction wheels with on-board steering systems for electric vehicles.
Each WheelMax Steering Drive combines a traction wheel with tire, epicyclic gearbox, robust steering gear and bearing system, and two rugged PMDC brush motors, one for traction and one for steering power. The complete assembly is compact, easy to mount, and requires little to no maintenance. Applications include AGVs, autonomous robotic material handlers, pushers and tuggers, powered utility carts, and hospital patient handlers, among many others.
WheelMax Steering Drives handle loads up to 227 kg (500 lb) and provide 14 Nm (120 lb-in) continuous torque at speeds of up to 5 km/hr (3 mph). The traction motor is equipped standard with a holding brake and an incremental encoder. Standard tire material is polyurethane 95 Shore A for excellent traction, long life, and low noise. The design makes the exchange of wheel and tire easy to accomplish with minimal effort. Alternate tire materials, mounting arrangements, and feedback encoders are available.
WheelMax Steering Drive highlights include:
- Load carrying capacity class of 227 kg (500 lb) at up to 5 km/hr (3 mph)
- Up to 14 Nm continuous wheel torque and 250 Watts
- Optimized helical gear geometry minimizes noise and vibration
- Tapered roller bearing supports the wheel’s load, and an axial bearing supports radial loads
- IP40 protection level
Additional WheelMax options include: models compatible with 48 VDC power source instead of 24 VDC, brushless motor (with/without integrated drive electronics) for traction and/or steering power, flexible wiring for high cycle rotation, and manual-release holding brake.
