A vehicle wheel supporting rolling bearing unit includes a stationary side bearing ring member, a rotation side bearing ring member, and plural rolling elements. The rotation side bearing ring member is provided with a first acceleration sensor, a second acceleration sensor, and a third acceleration sensor which are fixed on a virtual plane orthogonal to a center axis of the rotation side bearing ring member. The first acceleration sensor and the second acceleration sensor are arranged on a virtual line passing through a rotation center of the rotation side bearing ring member with a same distance from the rotation center while detection directions thereof are directed in a radial direction and are opposite to each other in the radial direction. The third acceleration sensor is arranged such that a detection direction thereof is non-parallel to the detection directions of the first acceleration sensor and the second acceleration sensor.

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.

A vehicle wheel supporting rolling bearing unit includes a bearing part having a stationary side bearing ring member which is supported and fixed to a suspension device and non-rotatable in a use state and a rotation side bearing ring member which is coupled and fixed to a vehicle wheel and rotate together with the vehicle wheel, an electric generator which generates electric power to be supplied to a sensor provided on the vehicle wheel, a battery which stores the electric power generated by the electric generator, and a wireless communication device which wirelessly communicates an output signal of the sensor with an electronic equipment arranged on a vehicle body side. The stator is supported and fixed to the stationary side bearing ring member, and the rotor, the battery and the wireless communication device are supported and fixed to the rotation side bearing ring member.

Disclosed are modular mechanical assemblies formed from durable, corrosion resistant components with sufficient strength to maintain efficient operation. The modular mechanical assemblies include a novel torsion axle assembly having a cartridge that houses a torsion bar with a splined tip. A load bearing, relatively incompressible bushing is optionally disposed about the torsion bar. The cartridge is inserted into an axle tube, and an end cap is placed over the cartridge and torsion bar. The end cap is affixed to the axle tube such that the bushing is secured within a bore in the end cap. The torsion bar tip extends through the bushing and end cap and is secured within a torsion arm. A spindle is also secured within the torsion arm. One or more components of the torsion axle assembly are made from a low alloy, medium carbon steel material that provides corrosion resistance and advantageous yield and ultimate strength properties. One or more components of the assembly can also be coated to improve corrosion resistance. Suitable coating techniques include, but are not limited to liquid ferritic nitrocarburizing, gas nitriding, electroless nickel plating, or a diamond like carbon coating process.

Provided is a steering system capable of enhancing traveling stability when a vehicle drives straight and improving small-turn performance. The steering system includes: a first steering device; a second steering device including a mechanical section configured to individually steer each of left and right wheels by driving a steering actuator and a control section configured to control the steering actuator; and a vehicle information detection section configured to detect a velocity of the vehicle and a steering angle. The control section includes a turning angle control module configured to control the steering actuator pursuant to a predetermined rule in accordance with the velocity of the vehicle and the steering angle so as to control turning angles of the left and right wheels.

A hub lock nut assembly for retaining a vehicle wheel hub in position. The hub lock nut assembly comprising a hub lock nut and a mating component with which the hub lock nut is arranged to be mated in a mated position. The hub lock nut comprises a circumferential inner wall defining a central hole, the inner wall having a threaded portion. One of the hub lock nut or the mating component comprises at least one resilient portion adapted to be movable in a radial direction outwardly of the central hole when subjected to an external force provided by the other of the mating component or the hub lock nut. The at least one resilient portion having an engagement area for receiving said external force, wherein the engagement area is located radially outwardly of the threaded portion.

A rear axle of a commercial electric vehicle includes a curved de Dion axle that includes stub axles, CV cups, each configured to receive a portion of a CV axle, and a central portion disposed downward and rearward of the stub axles. The rear axle includes a curved form factor to allow for a portion of an electric drive unit to be disposed in a manner where a hub centerline connecting the stub axles intersects the electric drive unit.
