Abstract: A wheel removal tool for a toy vehicle wheel has a tool base body and at least one rear-engagement portion. The latter is connected fixedly to the tool base body and is embodied so that it, in a removal starting position, engages behind an assigned removal portion of the toy vehicle wheel. A removal lever of the removal tool has a supporting portion for support on a vehicle component fixed on the chassis. The removal lever is adjustable relative to the tool base body between the removal starting position and a removal end position. In the latter, the at least one rear-engagement portion is displaced relative to the supporting portion in a removal direction. This results in a removal tool with which a simple detachment, which is in particular close to reality, of the toy vehicle wheel from a chassis-side vehicle component is enabled.

Abstract: A mobile radio communication system estimates the positional relationship between an own moving terminal and another moving terminal around a view obstruction. If the absolute value of the difference between detected reception power levels is lower than a first power threshold value, the own moving terminal determines that the other moving terminal is positioned within the visual range of the own moving terminal, the distance from the own moving terminal to the other moving terminal being shorter than a predetermined distance BP, or that the other moving terminal is positioned outside thereof, the distance to the visual range of the own moving terminal being shorter than the predetermined distance BP. Also if the absolute value is higher than or equal to the first power threshold value, the own moving terminal determines in a similar manner.

Abstract: The invention provides motorist a lock-unlock wheel that rotates independently around its center hub, which remains mounted to the axle of a subject vehicle. The rim allows vehicles to be towed without vehicle axle rotation, while eliminating odometer reading due to towing. The invention comprises an inner hub spindle that is able to be unlocked from the outer wheel's rim, allowing for independent rotation of the inner spindle. And, when unlocked via a bolting system, the invention's outer rim section rotates while also eliminating effects of a vehicle drive and brake system while the vehicle is in tow.

Abstract: A lug nut for a golf trolley wheel has a base panel, an engaging element and a spring. The base panel has a mounting hole and a chamber respectively formed transversely and radially through the base panel and communicating with each other. The engaging element is movably mounted in the base panel and has a circular hole and an engaging hole formed through the engaging element, communicating with each other and selectively aligning with the mounting hole. The spring presses the engaging element to an engaging position, wherein the engaging hole aligns with the mounting hole to mount a trolley wheel and is compressed to remove the wheel.

Abstract: The quick-change adjustable track center front hub assembly is secured to a spindle axle of a sprint car by a friction drive bearing system located between the spindle axle and the front hub assembly. The bearings are spaced apart to provide increased side and torsional load carrying capability. In addition, the hub includes a section of external splines for accepting at least one spacer and a wheel center section both having internal splines for mating with the external splines on the hub. A single lug nut connects to the outboard end of the hub for securing the spacers and wheel center sections to the front hub assembly to provide a quick-change arrangement not found before in sprint-type cars. A brake rotor is attached to the hub inboard of the spacers and wheel center section, thus allowing unimpaired accessibility to the wheel center section and spacers for quick-changing and adjusting the track center of the front wheels of the sprint-type cars.

Abstract: A carrier permits a parachute washer to be mounted in a recess in a push-on wheel. The carrier has a flange that engages a shoulder in the recess to provide proper positioning and alignment. The parachute washer is held in a hat-shaped slot by a bump so that the hole through the washer is sufficiently coaxial with a first opening in the carrier to permit the wheel, carrier and washer to be slipped onto the axle. Should wheel removal be necessary for any reason, a dowel rod may be inserted in an opening in the opposite side of the carrier and the axle driven out of the washer.
