A tandem wheel assembly or kit has a housing that includes a central chain box, a first wheel end casing, and a second wheel end casing. The central chain box has an internal volume extending between a first box end and a second box end, a unitary pivot portion having a box opening disposed about a pivot axis, a first box flange with a first box flange face and a second box flange with a second box flange face. The first wheel end casing has a first wheel end flange with a first wheel end flange face mateable with the first box flange face, a first wheel end opening, and defines a first length. The second wheel end casing has a second wheel end flange with a second wheel end flange face mateable with the second box flange face, a second wheel end opening, and defines a second length.

This invention is for an improved combination chaise lounge and tote cart and especially to an chaise lounge and tote cart which can be folded to a storage position and can be quickly converted between a tote cart and a chaise lounge.

An electromagnetic wheel assembly includes a spindle that may be rotatably coupled to an axle of a vehicle. A wheel is removably positioned on the spindle. A hub is provided and the spindle is rotatably positioned in the hub. An electromagnet is coupled to the hub. The electromagnet is selectively turned on to magnetically engage the wheel thereby retaining the wheel on the disk. The electromagnet is embedded within the disk. A lock is movably coupled to the spindle. The lock is selectively urged into a locking position to inhibit the wheel from coming off of the spindle when the electromagnet fails. Additionally, the lock is selectively urged into an unlocked position to facilitate the wheel to be removed from the spindle.

An axle for a vehicle, wherein the axle includes a transverse axle portion having a longitudinal end. The axle including a first axle portion connecting the transverse portion to a chassis of the vehicle and a second axle portion connecting the transverse portion to a wheel carrier for supporting a vehicle wheel. A vibration damper is arranged in a receiver in one of the axle portions.

An action force detecting unit for a rotary member that detects a force acting on a rotary member such as a rotary shaft and a wheel easily and accurately. The action force detecting unit comprises: a first rotor rotated integrally with a tire; a second rotor rotated relatively to the first rotor; a case fixed to a vehicle body while rotatably supporting the first rotor and the second rotor; a first thrust bearing supporting the first rotor; a second thrust bearing supporting the second rotor; a load translating mechanism transmitting a torque between the first rotor and the second rotor while translating the torque partially into a thrust force; a detector fixed to the case to detect a flexure relating to the thrust force applied to the second thrust bearing; a calculator calculating the force acting on the tire based on the flexure detected by the detector; and a transmitter transmitting a signal in accordance with a torque calculated by the calculator.
