| 142 | Braking system for front caster wheels of a self-propelled vehicle | US12619532 | 2009-11-16 | US20100122875A1 | 2010-05-20 | Ted H. CORRIHER |
| A ride-on, self-propelled vehicle having front caster wheels, such as a zero-turn mower, includes a front brake system. The actuating power for the front brake pass through a spindle supporting the front caster wheel. In a preferred embodiment, a center shaft of each spindle or a concentric outer ring of a sleeve of each spindle passes a force from a brake actuator to a brake for the respective caster wheel. Actuation of the brake actuator moves a member into frictional contact with a portion of the front wheel or an object attached to the front wheel to applying a braking force. | ||||||

| 144 | Agricultural Implement Having Wheels That Caster | US12258097 | 2008-10-24 | US20100101812A1 | 2010-04-29 | Terrance A. Friggstad |
| An agricultural implement includes a hitch boom to which a pair of wing booms is pivotably connected. The wing booms are designed to fold forward from an extended position to a transport position. The wing booms are supported above a surface by wheels that provide the aforementioned support when the wing booms are in an extended position as well as the transport position. Maintaining surface contact of the wheels in both positions reduces the load placed on the hitch to which the hitch boom is coupled as well as the hitch boom itself. Multi-link draft links are connected between the hitch boom and the wing booms to provide support for the wing booms when the wing booms are in the extended position. The relative length of the draft links dictates how far the hitch telescopes when the wing booms are folded to the stowed or transport position. | ||||||

| 152 | Wheel and tire assembly for recreational vehicles | US11186920 | 2005-07-22 | US07231949B2 | 2007-06-19 | William E. Tuggle |
| A wheel and tire assembly for recreational vehicles, such as mountainboards, motorized carts and pedaled carts is provided. The tire comprises a tire made of substantially inelastic material that will not stretch under a load. Thus, the tire will flatten under a load to provide a high level of traction on soft and irregular surfaces, as well as on hard and flat surfaces. The tire includes protrusions on its inner diameter surface for securely engaging the wheel. The wheel includes a rim that supports the tire and includes protrusions for engaging the protrusions of the tire in an interdigitating manner. The interdigitating engagement of the protrusions on the tire with the protrusions on the wheel prevents slippage and rotation of the tire relative to the wheel. The wheel also includes support flanges that extend radially inward from the rim in order to protect the tire from damage as the tire deforms under a load. | ||||||

| A suspension system for mounting a pair of wheels to a wheelchair is disclosed. The system includes a crossbar pivotally mounted to the wheelchair so as to pivot about a longitudinal axis. At least one spring assembly is located between the crossbar and the wheelchair frame for controlling the pivoting of the crossbar. A hinge assembly is mounted on each lateral end of the crossbar. The hinge assembly includes a first hinge component attached to the crossbar so as to be rotatable about a vertical axis, and a second hinge component resiliently connected to the first hinge component. The resilient connection biases the second hinge connection against rotation with respect to the first hinge component. A wheel and yoke assembly are mounted to the second hinge component. | ||||||

| A portable wheel assembly for use with bicycles and other wheeled vehicles. The wheel assembly comprises a centrally positioned hub which is adapted for rotatable movement about an axis. A plurality of pie shaped disk segments are coupled together along their radial side edges to form a circular support disk with a central opening. Each disk segment is adapted to removably couple with the hub at its innermost radial edge and extends radially outwardly to form a portion of a circular rim at its outermost radial edge. The rim is adapted for supporting a tire. The tire comprises a non-pneumatic tire with an annular ridge which is adapted to couple with the circular rim formed by the disk. During assembly, each of the pie shaped disk segments is coupled together and then coupled to the hub assembly at the inside radial edge or central opening. As the disk segments are coupled to the hub, the tire is assembled onto the outer radial edge or rim. Securing the supporting disk structure to the hub also secures the tire to the rim. | ||||||
| 158 | Method of making a light-metal strip wheel | US195314 | 1998-11-18 | US5933956A | 1999-08-10 | Meinhard Bonning; Ralf Duning; Uwe Gohrbandt; Gerhard Sollner |
| A light-metal strip wheel, in particular for motor vehicles, which includes a wheel disk and a rim. The wheel disk comprises two wheel-disk parts each having a ventilation hole. The ventilation holes have necks that when pressed into one another, secure together the two wheel-disk parts with the two parts separated from one another in the region surrounding the ventilation holes, while coming to rest on one another in a hub region. The space between the two wheel-disk parts in the region surrounding the ventilation holes increases the stiffness of the strip wheel so that the wheel is suitable for accommodating large loads. | ||||||

| 160 | Handcart wheel-mounting apparatus | US109685 | 1993-08-20 | US5314241A | 1994-05-24 | Chin-Chang Cheng |
| A handcart wheel-mounting apparatus includes a wheel mounted by means of a number of latches each biased by means of an elastic element, on a hub member in turn mounted by means of an annular washer and a cap, on a wheel shaft mounted on a wheel support. The hub member comprises a rim, an axial bore formed therethrough, a tubular bearing coaxially formed therethrough about the axial bore, a plurality of recesses formed therein about the axial bore, and a plurality of holes radially formed therethrough so that each of the holes communicates with a corresponding one of said recesses. A number of elastic elements are received in the recesses. A number of latches each are formed on a corresponding one of the elastic elements and the latches are biased through the holes by means of the elastic elements. The wheel shaft is inserted through a passage formed transversely through the wheel support, the annular washer, and the axial bore. Then, a tip of the wheel shaft is firmly fitted in the cap. Thus, the hub member is firmly mounted on the wheel shaft. The wheel is co-axially formed with a tubular portion and a number of sockets are transversely formed through the tubular portion. The hub member is mounted in the tubular portion having the holes aligned with the sockets. Then, the latches are inserted through the holes into the sockets. Thus, the wheel is mounted on the hub member. | ||||||
