A driveshaft coupling. Note the split damage beginning to appear, likely due to the large axial displacement. A giubo. A giubo (/ ˈ dʒ uː b oʊ / JOO-boh; etymology: giunto Boschi, "Boschi joint"), also known as a 'flexdisc', and sometimes misspelled as guibo, is a flexible coupling used to transmit rotational torque between the drive shaft and the companion flange on mechanical devices ...
The torque tube consists of a large diameter stationary housing between the transmission and rear end that fully encloses a rotating tubular steel or small-diameter solid drive shaft (known colloquially in the U.S. as a "rope drive" [1]) that transmits the power of the engine to a regular or limited-slip differential. [2]
Rear-wheel drive cars have commonly used a lengthwise propeller shaft with a rubber doughnut joint at the gearbox end (limited movement) and a universal joint at the rear axle (greater movement), or vice versa. This gives articulation where needed, but also stops some of the vibration being transmitted into the body.
Like other flexible couplings, jaw couplings are limited in the shaft misalignment that they can accommodate. Too much axial motion will cause the couplings to come apart, while too much angular or parallel misalignment will result in bearing loads that may lead to premature system wear or failure.
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to ...
Flexible shaft tool. A flexible shaft, often referred to as a flex shaft, is a device for transmitting rotary motion between two objects which are not fixed relative to one another. It consists of a rotating wire rope or coil which is flexible but has some torsional stiffness. It may or may not have a covering, which also bends but does not rotate.
The name refers to the ability of the disk to flex along its main axis to account for gear changes and/or small misalignments as rotational speeds change. [2] Flexplates are generally much thinner and lighter than flywheels not only because of the required flexibility, but also due to the smoother coupling action of the torque converter [3] and the elimination of the clutch surface.
Torque reaction effects on a leaf spring in a Hotchkiss drive system. Most shaft-drive systems consist of a drive shaft (also called a "propeller shaft" or Cardan shaft) extending from the transmission in front to the differential in the rear. The differentiating characteristic of the Hotchkiss drive is the fact that the axle housing is firmly ...
