| In a frictional drive vehicle, a load acting on the vehicle such as the weight of a rider is converted into a force that urges two frictionally engaging parts (3L, 3R, 25) toward each other. Thereby, the contact pressure between the two frictionally engaging parts is maintained at an optimum level under all conditions. A weight of a rider may be transmitted to a drive member that frictionally engages a main wheel via a four-link parallel link mechanism (40, 50). | ||||||

| A furniture glide includes an upper portion for mounting to a furniture leg and a lower portion having a plow base. The plow base includes a lower pad segment having an outer wall that extends downwardly to a bottom sliding surface for sliding on a floor. The outer wall is substantially perpendicular to the sliding surface, forming a sharp outer edge that acts as a plow when the furniture glide is slid along the floor to push dirt or other debris out of the path of the furniture glide. In another embodiment the lower portion of the glide is a two-piece sub-assembly which includes a mounting member having vibration absorbing and/or sound deadening properties. | ||||||
| 129 | Internal Elastomer Damper for Vehicular Propeller Shafts | US11614436 | 2006-12-21 | US20080153367A1 | 2008-06-26 | George Zhu |
| Ringing noise in a tube or in tubes comprising a propeller shaft of an automotive drive is attenuated by an elastomeric ring positioned in each shaft. The elastomeric ring is a split ring, preferably made of recycled rubber, wherein the ring normally has a rectangular shape and is bent into a cylindrical shape for insertion in the tube. The outward bias of the ring is sufficient to hold the ring in place within the tube, while a gap in the material of the ring allows the ring to exert further expansive force against the inner surface of the tube while the tube is rotating. A single ring located midway between the ends of a tube is sufficient to attenuate ringing noise in one example of a tube, however a plurality of spaced rings may be used in other tube configurations to attenuate ringing noise. Preferably, the elastomeric ring has an axial extent of about 5% of the length of the tube. | ||||||

| A plurality of rotating bodies rotated in the direction orthogonal to the straight-forward direction of a wheel are disposed around the wheel in the wheel having rotating bodies provided with non-turning type rotating bodies. Each rotating body is rotatably supported around the axis of rotation across the radial direction around an axle, and each rotating body is formed in a shape in which an arc of the outer circumferential circle of the wheel is formed by a circumferential surface with the diameter of a tip portion smaller than the diameter of a base end portion. As a result, generation of a space between the rotating bodies can be suppressed. | ||||||
| 131 | WHEEL END ASSEMBLY | US09969296 | 2001-10-02 | US20030062765A1 | 2003-04-03 | Patrick B. Melton |
| A wheel end assembly is provided which facilitates maintenance of the wheel end assembly, and further provides a more secure bearing housing. The spindle is caused to rotate with the drive axle, and is in turn connected to drive a wheel hub.

A tone wheel is sandwiched between two nuts, and is caused to rotate with the spindle. The tone wheel includes a tab extending into an opening on the washer such that the washer rotates with the tone wheel. The overall assembly facilitates maintenance and assembly, and provides a more secure environment for the bearing structure. | ||||||
| 132 | Method for designing low vibration omni-directional wheel | US10273165 | 2002-10-18 | US20030034687A1 | 2003-02-20 | Donald Barnett Harris |
| An omni-directional wheel for an omni-directional vehicle that exhibits constant ride height, low vibration, and reduced maximum ground contact pressure is disclosed. The invention consists of a wheel assembly rotatably connected to the omni-directional vehicle chassis. The wheel assembly comprises a hub on which free spinning rollers are rotatably mounted at an angle to the wheel axis. Constant ride height and low vibration operation are accomplished by configuring the rollers with an exterior profile, thickness, material properties and surface grooving to achieve constant deflection of the roller contact surface at all wheel rotation angles. | ||||||
| 133 | Suspension and steering system for a vehicle | US09365253 | 1999-07-30 | US06406043B1 | 2002-06-18 | Charles Balmer |
| A steering and suspension arrangement for agricultural vehicle includes a horizontal axle transverse to the direction of movement with the ground wheel mounted at each end of the axle. The length of the axle can be adjusted by extending and retracting end portions of the axle relative to a centre section of the axle. Each end of the axle carries a wheel hub on a suspension arrangement defined by an upper plate, a lower plate, a first channel member attached to the lower plate and a second channel member attached to the upper plate with the channel members facing each other and connected by two parallel pivoting links. Between the plates is mounted a gas bag spring. The frame is divided into a front portion and a rear portion which are held against steering movement but can pivot, each relative to the other about a horizontal axis along the direction of travel to accommodate twisting beyond the limited suspension movement. The steering is effected by steering movements of the front wheels controlled by two separate cylinders which are arranged in a hydraulic circuit which automatically compensates for any fluid leakage to maintain the wheels aligned. | ||||||

| 136 | Magnetic wheel | US266368 | 1999-03-11 | US6125955A | 2000-10-03 | Carl Zoretich; Daniel Garman |
| An improved magnetic wheel for a vehicle that moves over ferromagnetic surfaces. The vehicle includes an articulating, remotely controlled chassis that is constructed around a variable frequency motor. Drive axles extend from spring biased torsion hubs and are supported at resilient bushings at each wheel. Each wheel includes a number of adjoining annular permanent magnet pole sets. Permanent magnet disks are arrayed around the circumference of each pole set. At least one pole set is secured to a wheel hub and the others are supported from resiliently mounted registration pins. The resiliently mounted pole sets are able to flex with encountered irregularities at the work surface as the axle tracks and independently flexes with the surface changes. | ||||||
| 137 | Variable outer diameter wheel for vehicles | US740092 | 1996-10-24 | US5839795A | 1998-11-24 | Yutaka Matsuda; Kaoru Shimizu |
| A variable outer diameter wheel includes a generally cylindrical pipe or drum having four equally spaced penetrating holes or receiving parts in the cylindrical wall, a diaphragm sealing member corresponding to each of the penetrating holes and fitted to the pipe support, and sliders forming a wheel peripheral face so that the sliders can smoothly slide in the penetrating holes. The sliders are pushed or activated and moved outward from the pipe in a direction so the wheel outer diameter is enlarged by compressed air supplied through a passage and a hole provided in an axle which support the wheel. Exhausting the compressed air causes the wheel outer diameter to decrease and restores the wheel to its original size. Variable outer diameter wheels permit safe operation of vehicles on frozen, snow-clad or irregular surfaced roads. | ||||||
| 138 | Skate train | US312564 | 1994-09-26 | US5560300A | 1996-10-01 | John R. Schneider |
| To provide a railroad car design that allows the car to travel at high speeds over current roadbeds at very low fuel costs per mile a special rail is formed. This rail has the form of a wave shaped on its top with the troughs and crests of the wave repeating themselves every several feet apart continuously down both tracks for the whole distance of the railroad. When a wheel of this multi-wheeled car comes over the crest of a wave it has encountered as it moves down this wave formed track, the wheel immediately begins supporting its computer calculated portion of the weight of the car on a cushion of air pressure forced into its supporting air cylinder at that moment and rolls down the face of the wave in its desired direction of travel. Upon reaching the bottom of the wave's trough and starting to roll up the up hill portion of the wave form, the wheel is pushed back up into its supporting air cylinder thus expelling the trapped air by the upgrade created as the track shade ascends back up out of its trough to form the next wave crest. To stop the car, the trapped air pressure in the extended air cylinder is not allowed to exit its cylinder as fast as it normally would as each wheel is retracting on the upgrade out of its wave's trough. | ||||||
| 139 | Internal conduit vehicle | US496827 | 1995-06-29 | US5551349A | 1996-09-03 | Leon J. Bodzin |
| An internal conduit vehicle comprises two coaxially aligned dual-vector wheels mounted to each end of a chassis. The wheels include multiple, elongated rollers each positioned at an angle around a hub assembly. Two motors mounted to opposite ends of the chassis are rotationally coupled to a hub assembly. A motor control system mounted to the chassis drives the motors so that the wheels counter-rotate with equal, but opposite torque, thereby driving the vehicle axially through a conduit. | ||||||
