A device for controlling the temperature of a hub includes a hub bearing mounted at a central hole of the hub, an axle mounted in the central hole through the hub bearing, an end cover mounted on a wheel disc outside the hub bearing, a temperature sensor, a water return passage, a motor, a turbine, a water storage tank, a water outlet passage, a wind driven generator, a rectifier, a battery, a controller and other components, wherein the water storage tank is arranged inside the axle and connected to the water outlet passage and the water return passage, the water passages are arranged inside the axle and connected to fluid, the turbine is arranged at the bottom of the water storage tank, and the turbine is driven by the motor at the bottom of the water storage tank.

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.

A suspension for a two-wheeled vehicle includes first and second fork legs. Each fork leg includes a dropout. Each dropout has an opening therethrough. At least a portion of one of the openings is threaded. Each of the dropouts includes a split-damp pinch bearing defining the opening and operable between an open position and a locked position, and a hand operable actuator pivoted to the bearing for operation thereof. The suspension further includes a one-piece axle. The axle is disposed through the openings. The axle has a threaded first end engaged with the threaded portion. The axle has an ergonomic grip formed at a second end. The bearing tightly engages an outer surface of the axle in the locked position, thereby rotationally coupling the axle to the dropout.

An inner ring (10a) of a hub is fitted around a fitting tube part (11) in a state where an axially outer end of the inner ring abuts on a step surface (12), and the axially inner end surface of the inner ring is pressed by an axially outer surface of a pressing part (17) of a clamp portion (13a). Thereby, a hub body (9a) and the inner ring (10a) are fixedly coupled. The clamp portion (13a) has an engaging recess (19) that extends in a radial direction. The inner ring (10a) has an engaging protrusion (21) that is engaged with the engaging recess (19).

Systems and apparatuses include a chassis mount configured to couple to a vehicle chassis, an axle assembly including wheels, a four-bar linkage coupling the axle assembly to the chassis mount, and a hydraulic cylinder coupled between the chassis mount and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position and acts as a spring damper suspension component.

A cap is provided for covering the threaded end of a removable spindle, having a cover with thread engaging tabs extending from a reservoir basin. The tabs include surface projections for retaining the cap to the spindle threads. The tabs are formed to fit within available slots of a slotted hex nut connected to the spindle. The cap includes a separately formed skirt or guard to make flexible surface contact with the torsion arm or spindle supporting structure. The skirt can include a sacrificial anode region to provide cathodic protection for the spindle threads and spindle retention nut. The skirt is removable from the cap so that the cap can be reused with a new skirt. The cap is formed to be used with existing spindle assemblies and to be reusable.

An aircraft landing gear bogie beam including first and second ends and a mounting bearing for connection to an aircraft landing gear main strut between the ends. Each end has a respective axle, and each axle defines a wheel mounting portion on each side of the bogie beam. The bogie beam is arranged to enable the first and second axles to each pivot relative to the bearing about a respective longitudinal axis of the bogie beam by an amount that is sufficient to place a wheel rim of a wheel assembly in contact with the ground in the event of a tyre of the wheel assembly deflating.
