Sectioned 3-speed manual 'crash' gearbox, for a car c. 1935. A layshaft is an intermediate shaft within a gearbox that carries gears, but does not transfer the primary drive of the gearbox either in or out of the gearbox. [1] [2] Layshafts are best known through their use in car gearboxes, where they were a ubiquitous part of the rear-wheel ...
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]
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 ...
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 ...
The selector is typically symmetric: it slides between two gears and has a synchromesh and teeth on each side in order to lock either gear to the shaft. Unlike some other types of clutches (such as the foot-operated clutch of a manual-transmission car), a dog clutch provides non-slip coupling and is not suited to intentional slipping.
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 attached to the leaf springs to transfer the axle torque through them ...
Three-speed sliding-gear non-synchronous transmission Non-synchronous "crash" gearbox; commonly used today in semi-trucks and tractors, and formerly used in automobiles pre-1950s. A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require ...
Pitman arm Steering box, with the pitman arm just visible beneath. A Pitman arm is a shaft that translates rotary or angular movement into linear movement, or vice versa. Pitman arms are commonly found in water pumping windmills, automotive steering systems, and sewing machines. In windmills, the Pitman arm connects the driving gear to the ...
