In a rotary electric motor, a stator contains a plurality of separate electromagnet core segments disposed coaxially about an axis of rotation. The core segments are affixed, without ferromagnetic contact with each other, to a non-ferromagnetic support structure. The rotor is configured in a U-shaped annular ring that at least partially surrounds the annular stator to define two parallel axial air gaps between the rotor and stator respectively on opposite axial sides of the stator and at least one radial air gap. Permanent magnets are distributed on each inner surface of the U-shaped rotor annular ring that faces an air gap. A winding is formed on a core portion that links axially aligned stator poles to produce, when energized, magnetic poles of opposite polarity at the pole faces.

Systems and methods for determining operation of a cylinder deactivating/reactivating device are disclosed. In one example, degradation of the cylinder deactivating/reactivating device is based on intake manifold oxygen concentration.

A gear ratio shift control and control method controls gear ratio upshifts in a multiple-ratio transmission for an automotive vehicle. Pressure actuated friction elements establish torque flow paths in transmission gearing as they are selectively engaged and released. A net torque reduction at a transmission torque output shaft during an upshift event is reduced by increasing transmission input torque prior to the start of the inertia phase of the upshift event.

A magnetic force rotation device includes a rotor and a stator. The rotor is provided with a plurality of magnetic assemblies containing permanent magnet. The plurality of magnetic assemblies are arranged along the circumferential direction of the rotating shaft to form a wheel-shaped ring, and each magnetic assembly is provided with two magnetic poles. The stator is provided with a plurality of magnetically isolated electromagnets coaxially arranged.

The wheel-shaped ring of the stator is at least party surrounded by the wheel-shaped ring of the rotor, so that each pole of the paired poles of the electromagnets of the stator corresponds to one magnetic pole of the two magnetic poles of the magnetic assemblies of the rotor respectively. Two axial component air gaps are provided between the rotor and the stator. One of the above two axial component air gaps and two radial component air gaps are provided between one of the paired poles of the electromagnets of the stator and one corresponding magnetic pole of the two magnetic poles of the magnetic assemblies of the rotor.

A brushless electric machine includes a rotor and a stator. Each of the twin poles of the stator electromagnetic members corresponds to one of the two magnetic poles of the rotor magnetic assembles. Two radial component air-gaps are arranged between the stator and the rotor to separate the stator and the rotor. Axial component air-gaps axially corresponding are arranged between the stator poles and the corresponding rotor poles to separate the stator poles and the rotor poles. The stator wheel-shaped ring is partly surrounded by the rotor wheel-shaped ring.

A threaded joint comprises a coupling, a first pin, and a second pin, wherein the thread of the first pin has a pitch different from the pitch of the thread of the second pin.

A crankshaft damper hub (10) for attachment to an engine crankshaft (34) has an outer rim (44) and a center portion (46). The center portion (46) has a passageway (56) formed therethrough for receipt of an engine crankshaft (34). A plurality of spokes (60) extend between the outer rim (44) and the center portion (46). An opening (66) is formed in each of the plurality of spokes (60) with a tab (72) formed therein for engagement with a tool to facilitate removal of the hub (10) from the crankshaft (34).

The tracks of the present invention utilize cut pieces of reinforcement which are associated with each individual drive lug. By using individual pieces the lugs can be easily built up with multiple layers of rubber and reinforcement. The cut pieces can be strategically shaped and placed to optimize their effect to realize improved performance and durability of the track. Incorporation of such inner fabric reinforcement layers adds stiffness to the lugs and thereby increases the torque capacity of the track. Additional layers also provide increased damage resistance after the outer layers of fabric are worn away, and added layers improve wear resistance on the sides of the lugs due to undercarriage misalignment and track-to-wheel contact when the vehicle turns during normal operations.

An additive compound comprising a non-borated and/or borated reaction product, in which the reaction product is obtained by reacting a linear or branched, saturated or unsaturated monovalent aliphatic acid having 8 to 22 carbon atoms, urea, and polyalkylenepolyamine, when employed in a lubricating oil composition is favorably employable as an automatic transmission fluid of internal combustion engines.
