- Axe
- Trade name for a range of digital switches manufactured by the Swedish company I. M. Ericsson Telefonaktiebolaget.
- Axes
- Plural of axis. When describing points on the body of a vehicle, they can be named from three parameters: its length (longitudinal), height (vertical), and width (cross-car). These three axes or dimensions are labeled X-Y-Z. See
- Axial compressor
-
- A compressor characterized by the unusual piston arrangement. The pistons are arranged horizontally around and parallel to the crankshaft axis or centerline.
- A multistage, high-efficiency compressor comprising alternate rows of moving and fixed blades attached to a rotor and its casing respectively.
- Axial-flow compressor
- A compressor in which alternate rows of radially-mounted rotating and fixed airfoil blades pass the air through an annular passage of decreasing area in an axial direction.
- Axial-flow turbine
- Characteristic aero-engine turbine, usually of 1-3 rotating stages, in which the gas flow is substantially axial
- Axial pitch
- The distance from any point on one thread or helix to the corresponding point on the next thread or helix measured along the axis of the screw or helix.
- Axial ratio
- Ratio of major to minor axis of polarization ellipse for e.g., a wave propagated in waveguide, polarized light. Also called ellipticity
- Axial response
- The response of a microphone or loudspeaker, measured with the sound-measuring device on the axis of the appearance being tested.
- Axial runout
- Variation from the plane normal to its axis of a rotating part. Its wobble, rather than its eccentricity. Compare radial runout
- Axiotron
- Valve in which the electron stream to the anode is controlled by the magnetic field of the heating current
- Axis
-
- The centerline, whether real or imaginary, around which a thing rotates.
- One of the three axes of an aircraft, which are the straight lines through the center of gravity about which change of attitude occurs longitudinal or drag axis in the plane of symmetry (roll); normal or lift axis vertically in the plane of symmetry (yaw); and the lateral or pitch axis transversely (pitch).
- Of a lens, the line of symmetry of the optical system; the line along which there is no refraction.
- Axis of a weld
- An imaginary line along the center of gravity of the weld metal and perpendicular to a cross section of the weld metal.
- Axle
- An axle is a shaft on which the wheels revolve. A full-floating axle is used to drive the rear wheels. It does not hold them on nor support them. A semi-floating or one-quarter floating axle is used to drive the wheels, hold them on, and support them. A three-quarter floating axle is used to drive the rear wheels as well as hold them on, but it does not support them. A live axle holds the wheels and transmits power to the wheels. A dead axle or beam axle merely holds the wheels, but does not transmit power to the wheels.

- Axle articulation
- The degree to which an axle can move up and down. Off-road vehicles need a great deal of axle articulation to allow for extremely uneven terrain, such as rocks or gullies.
- Axle-box
- Box-shaped housing containing the axle bearings and lubricant. Constrained laterally on guides and supports the weight of vehicle through springs.
- Axle casing
- A British term indicating a tubular housing which encloses the differential and half-shafts along with their bearings. The US term is axle housing.
- Axle designation
- A numeric expression such as '4x2,' '6x4,' which describes the total number of wheels followed by the number of driven wheels. Thus '4x2' is a vehicle with four wheels on two axles, but only two wheels (on the one axle) drive the vehicle. In contrast, a '4x4' has four wheels on two axles and both sets of axles drive the vehicle.
- Axle end gears
- The two gears, one per axle, that are splined to the inner ends of the drive axles. They mesh with and are driven by the spider gears.
- Axle housing
- An American term indicating a tubular housing which encloses the differential and half-shafts along with their bearings. The British term is axle casing.
- Axle parallelism
- Axles are determined to be parallel, thus minimizing tire wear, if a measurement between two or more axles is equal at both ends of the axle.
- Axle shaft
-
- The short shaft which connects the differential and the drive shaft on each side of an independent suspension configuration.
- The drive shaft or halfshaft of a rigid axle.
- Axle stand
- An adjustable height tripod used to support a vehicle when working underneath it. Although you can raise the car with the jack, use a pair of axle stands for safety. Also called Jack stand or Safety stand
Axle stand
- Axle tramp
- A form of wheel hop which is usually found in live rear axle cars. It occurs when sudden torque loads on the suspension cause the driven wheels to shake violently by slightly rotating the wheels and then springing back.
- Axle tube
- The part of the axle housing which covers the half-shaft or a tubular rigid axle.
- Axle wind up
- The phenomenon in which the torque transmitted to the wheels by the axle which causes the live axle to turn in its own centerline.
