The invention relates to a shield-shaped side-wall protection element for a vehicle tire and to a protective device for vehicle tires. In order to provide a side-wall protection element for vehicle tires that can optimally protect a tire side wall under rough conditions, that can be produced economically, and is easy to install, the invention provides a shield-shaped side-wall protection element for a vehicle tire, comprising a radially inner base, an outer edge, which forms the radially outer end and which extends in a circumferential direction, and with a shield segment, which extends from the outer edge at least to the base, wherein the outer edge is at least partially offset axially inward from the base). The protective device for vehicle tires according to the invention comprises a plurality of shield-shaped side-wall protection elements arranged overlapping in the manner of shingles in a circumferential direction.

A tire traction device which may improve or provide tire traction for various vehicles is described. The tire traction device includes a board having a first end and a second end, wherein the first end has a curved edge and the second end has a slanted edge. The board may include more than one section. The board includes a rough or grooved top surface, and a plurality of spikes extend from the bottom surface of the board. The tire traction device may also include a flexible component attached to the board. The flexible component is designed so that it may be drawn underneath a spinning tire.

A caster wheel assembly of a pickup for an agricultural machine, comprising a wheel on a carrier shaft mounted rotatably within a bushing of a pickup arm. The wheel being biased by a spring to be oriented in a predetermined direction relative to the pickup arm. The spring is mounted over the pickup arm between a first arm fixed to the carrier shaft and a second arm fixed to the pickup arm.

A vehicle traction jack that functions as a traction mat platform, ramp, and vehicle jack to assist a vehicle's tire when a tire is stuck in a rut, hole, or some sort of terrain or weather condition such as sand, gravel, dirt, mud, or snow is disclosed. The traction jack comprises a first plate and second plate, a hinge assembly, and a removable center jack mechanism. The first and second plates can extend to a partially-opened or fully-opened position forming a ramp and traction mat platform. The removable center jack mechanism attaches to first plate and second plate via pins. Easily stored in a vehicle at all times, a single user can use the traction jack to help move any type of vehicle's tire.

摘要:
A device for mounting a wheel to a vehicle having a housing for an axle, the device including a shaft, the shaft having a first end insertable into the housing and comprising a device for frictionally engaging an inner wall of the housing, a second end of the shaft comprising a support for mounting a wheel thereon. In one preferred embodiment, the frictional engaging device is threadably received on the first end of the shaft for expanding into contact with the inner wall of the housing in response to rotation of the shaft in a first direction and for contracting in response to rotation of the shaft in a second direction. In an alternate embodiment, the device comprises a disk mounted on the end of the shaft and adapted to come into frictional engagement with the inner wall of the housing by the weight of the vehicle.

A freely rotatable wheel assembly including a one-piece freely-rotatable annular rim having a central opening therethrough. The rim is of a hard low-friction material and has an inner surface which surrounds the opening for defining an outer bearing race. A bearing positioned within the central opening creates a low-friction rolling engagement between the rim and a shaft which is coaxially positionable in the opening. The bearing includes cylindrical rollers constructed of hard low-friction nonmetallic material. The rollers are uniformly angularly spaced around the rotational axis so that the roller axes define a circular locus about the rotational axis. The rollers are individually disposed in direct rolling engagement with the outer bearing race and with an inner bearing race defined by the shaft. A pair of annular retainers are disposed concentrically with the central opening adjacent the opposite ends thereof so that the rollers are disposed axially therebetween. The retainers are freely rotatable relative to both the rim and the shaft. An axle extends parallel to the rotational axis and has the opposite ends thereof freely rotatably supported on the retainers. Each axle has a respective roller freely rotatably supported thereon.
摘要:
Bearing assembly for a wheel primarily for use in casters produced under high production conditions. The bearing is characterized by the provision of a solid shaft with staked ends in association with a resilient seal all arranged for producing a bearing capable of inexpensive manufacture under high production conditions, but also a bearing having close tolerances and thereby capable of long and accurate operation.

A bearing assembly for a wheel having a substantially cylindrical and coaxial opening therethrough including cylindrical shell means slideably and snugly receivable into said opening and axially substantially coextensive with said wheel means adjacent said opening. Said shell means has a central portion of reduced diameter spaced from the opposite axial ends thereof to form annular recesses into which a pair of outer bearing races are snugly received. A cylindrical axle having a central portion of enlarged diameter is coaxially disposed within the central opening and spaced from the reduced portion of said shell. A pair of inner races are snugly sleeved upon the axle means snugly adjacent the opposite ends of the enlarged portion thereof, and radially aligned respectively with the outer races. A plurality of bearing balls are disposed between each pair of radially aligned races and the axle means is staked adjacent the remote sides of the inner races to firmly hold the inner races against said enlarged portion.
