Definitions
- This invention relates to omni-directional wheel modules and vehicles employing same. In further embodiments, this invention relates to methods of converting objects and non-omni-directional vehicles into omni-directional vehicles or hybrids thereof. In preferred embodiments, such modules are independently functional having an omni-directional wheel, an axle, a motor, a motor controller, a transmission, and a brake assembled together as a unitary assembly.
- Omni-directional vehicles capable of controlled motion in any direction have long been recognized as having many useful applications.
- a number of designs of omnidirectional vehicles have been disclosed.
- Most omnidirectional vehicle designs are similar in that they use wheels that feature a number of rollers positioned about the periphery of the wheel with the rollers permitting the wheels to support motion in directions at an angle to the wheel's plane of rotation.
- Omni-directional vehicles using such omni-directional wheels can move in any direction by- rotating the wheels and rollers in an appropriate combination.
- Each omni-directional wheel's rotation is mechanically driven and servo controlled in a coordinated fashion to cause the vehicle to follow a desired path as previously disclosed by lion in U.S. Pat. No. 4,598,782.
- omni-directional wheels Three, four, or more omni-directional wheels are connected to a suitable chassis, suspension, wheel drives, and controls to form an omni-directional vehicle.
- roller and “rollers” refer to the type of rollers used on or designed for omni-directional wheels for omni-directional vehicles.
- Omni-directional wheels can be grouped into two general classifications.
- the first class of wheels is comprised of a rigid hub that supports a number of free spinning rollers around its periphery.
- the hub is rigidly coupled to an axle that, along with other omni-directional wheels and axles, supports the vehicle.
- the rollers are mounted at an oblique angle to the wheel's axle and are free to rotate about their own axles.
- Omni-directional wheel roller mounting angles of ninety degrees have been disclosed by Blumrich in U.S. Pat. No. 3,789,947.
- the omnidirectional wheel disclosed by Blumrich was mechanically- driven to produce motion parallel to the axis of rotation of the wheel.
- Omni-directional wheel designs with a ninety- degree roller mounting angle and free-spinning rollers have been disclosed by Bradbury in U.S. Pat. No. 4,223,753; Hiscock in U.S. Pat. No. 4,335,899; Smith in U.S. Pat. No. 4,715,460; and Guile in U.S. Pat. Nos. D318,219 and D318,791.
- Omni-directional wheels with rollers mounted obliquely at roller mounting angles of approximately forty- five degrees with respect to the wheel shaft have been disclosed by lion in U.S. Pat. No. 3,876,255 and Amico in U.S. Pat. No. 5,701,966.
- U.S. Pat. Nos. 3,876,255 and 5,701,966 are hereby incorporated by reference in their entirety.
- the second class of omni-directional wheels differ from the above described omni-directional wheel design concepts in that the rotational axes of the free spinning rollers intersect with the wheel's axis of rotation. Wheels of this class have been disclosed by Bradbury in U.S. Pat. No. 4,223,753, and by Pin, et al, in U.S. Pat. No. 5,374,879. In wheels of this class, two or more spherical rollers are mounted in fixed positions so as to constrain the vehicle's motion in the direction of wheel rotation, while being unconstrained in a direction that is orthogonal to the wheel's axis.
- the axle supporting each roller may be mounted to the omnidirectional wheel hub at both ends of the roller, as disclosed by Blumrich, in the center, as disclosed by lion and Amico, or at intermediate locations, as disclosed by Smith.
- omni-directional wheel rollers are coated with an elastomer surface contact material to improve traction, as disclosed by Blumrich, lion and Smith.
- the ability to move in any direction or rotate within the perimeter of the vehicle is advantageous for any industrial or commercial vehicle that must be maneuvered within confined spaces (e.g. warehouses) or with particular precision, including forklifts, scissorlifts, aircraft support and maintenance platforms, munitions handling vehicles, cranes, motorized dollies, and delivery trucks.
- confined spaces e.g. warehouses
- forklifts, scissorlifts, aircraft support and maintenance platforms munitions handling vehicles, cranes, motorized dollies, and delivery trucks.
- forklifts are particularly improved when equipped with omni-directional capabilities.
- forklifts are vehicles with a hydraulically or mechanically powered liftforks that are used to lift, support and position a load.
- a scissorlift is a vehicle that features a work platform suitable for supporting a worker that is hydraulically or mechanically raised or lowered to place the platform at the elevation where work is to be accomplished.
- an omni-directional capable scissorlift requires fewer operator maneuvers and less room to position it in a desired location or orientation.
- Omni-directional capability permits the wheelchair operator to maneuver freely in confined spaces such as elevators and subway cars. The ability to move laterally at will is of particular value to wheelchair operators.
- Omni-directional mobility is also of value for a wide variety of industrial and military uses including material transportation within a factory, aircraft maintenance, and any other use where precise, controlled omni-directional motion is desired.
- the vehicle When such a wheel design is employed on a vehicle, the vehicle exhibits substantially constant ride height during directional operation thereby reducing vehicle vibration and allowing higher safe operational speeds.
- Other improvements in omni-directional wheels made by Airtrax, Inc. have increased the load carrying capacity of the wheels.
- an omni-directional wheel module comprising: an omni-directional wheel having a hub; an axle carrying the omni-directional wheel so that the omni-directional wheel is capable of rotating about the axle; a motor for powering rotation of the omni-directional wheel about the axle; a transmission operatively interconnected between the motor and the omni-directional wheel; and a brake for selectively inhibiting rotation of the omni-directional wheel; and wherein the module components are assembled as a unitary, functional modular wheel assembly selectively installable and removable as an assembled unit.
- the omni-directional wheel employed by said module is so constructed such that a vehicle employing a plurality of such omni-directional wheels exhibits substantially constant ride height during directional operation.
- the omni-directional wheel comprises: a plurality of roller mounting brackets coupled to the hub; and a plurality of rollers each rotatably coupled to at least one of the roller mounting brackets at a roller mounting angle, the rollers comprising; a core rotatably coupled to the roller mounting bracket, the core having a first end and a second end; and a contact surface of elastomeric material coupled to and radially disposed about the core with a volumetric shape such that the exterior profile of the contact surfaces of all the rollers forms a noncircular profile when viewed from a perspective laterally displaced from and coincident with the centerline of the hub.
- a vehicle comprising: a vehicle frame; a power storage device carried by the vehicle; a plurality of omni-directional wheels operatively connected to the vehicle; the power storage device being so connected to the motors of the plurality of omni-directional wheels such that the power storage device is capable of providing power to the motors to cause selective rotation of the plurality of omni-directional wheels.
- a method of converting an object into an omnidirectionally locomotable vehicle comprising: assembling a plurality of omni-directional wheel modules to the object.
- a method of converting a non-omni-directional vehicle into an omni-directional vehicle comprising: removing existing non-omni-directional wheels from a non-omni-directional wheeled vehicle; connecting a plurality of omni-directional wheel modules to the vehicle to impart to the vehicle omnidirectional functionality.
- a method of converting a non-omni-directional vehicle into an omni-directional vehicle comprising: connecting a plurality of omni-directional wheel modules to the vehicle to impart to the vehicle omnidirectional functionality.
- the omni-directional vehicle retains at least one non-omni-directional wheel.
- the non-omni-directional vehicle is a four-wheeled vehicle having four non-omni-directional wheels, and two of the non-omni-directional wheels are removed from the vehicle; and two of the non-omnidirectional wheels are retained on the vehicle.
