Most engines or motors deliver power as torque through rotary motion: this is extracted from the linear motion of pistons in a reciprocating engine; water driving a water wheel; or forced gas or water in a turbine. From the point of delivery, the components of power transmission form the drive train. Torque applied via an adjustable end wrench Relationship between force, torque, and momentum vectors in a rotating system In physics, torque (or often called a moment) can informally be thought of as rotational force or angular force which causes a change in rotational motion. ...

Driveshafts are carriers of torque: they are subject to torsion and shear stress, which represents the difference between the input force and the load. They thus need to be strong enough to bear the stress, without imposing too great an additional inertia by virtue of the weight of the shaft. Look up torsion in Wiktionary, the free dictionary. ... Shear stress is a stress state where the stress is parallel or tangential to a face of the material, as opposed to normal stress when the stress is perpendicular to the face. ...

Automotive driveshafts

Vehicles

Most automobiles today use rigid driveshafts to deliver power from a transmission to the wheels. A pair of short driveshafts is commonly used to send power from a central differential, transmission, or transaxle to the wheels. “Car” and “Cars” redirect here. ... In an automobile and other four-wheeled vehicles, a differential is a device, usually consisting of gears, for allowing each of the driving wheels to rotate at different speeds, while supplying equal torque to each of them. ... Look up Transmission in Wiktionary, the free dictionary. ... A transaxle, in the automotive field, is a component that combines the functionality of the transmission, the differential and the drive axle into one integrated assembly. ...


In front-engined, rear-drive vehicles, a longer driveshaft is also required to send power the length of the vehicle. Two forms dominate: The torque tube with a single universal joint and the Hotchkiss drive with two or more joints. This system became known as Système Panhard after the automobile company, Panhard et Levassor patented it. In automobile design, an FR, or front-engine, rear wheel drive means a layout where the engine is in the front of the vehicle and drive wheels at the rear. ...

In British English, the term "driveshaft" is restricted to a transverse shaft which transmits power to the wheels, especially the front wheels. A driveshaft connecting the gearbox to a rear differential is called a propeller shaft (or more commonly a "prop-shaft") and a driveshaft connecting a rear differential to a rear wheel is usually called a halfshaft. The name derives from the fact that two such shafts are required to form one rear axle. A propeller shaft connects a propeller to an engine. ...


There are different types of driveshafts in Automotive Industry:

  • 1 piece driveshaft
  • 2 piece driveshaft
  • Slip in Tube driveshaft

The Slip in Tube Driveshaft is the new type which also helps in Crash Energy Management. It can be compressed in case of crash. It is also known as a collapsible driveshaft.


Driveshaft for Research and Development (R&D)

The automotive industry also uses driveshafts at testing plants. At an engine test stand a drive shaft is used to transfer a certain speed / torque from the combustion engine to a dynamometer. A "shaft guard" is used at a shaft connection to protect against contact with the drive shaft and for detection of a shaft failure. At a transmission test stand a drive shaft connects the prime mover with the transmission. The phrase research and development (also R and D or R&D) has a special commercial significance apart from its conventional coupling of research and technological development. ... An engine test stand is a facility used to develop, characterize and test engines. ... A colorized automobile engine The internal combustion engine is a heat engine in which the burning of a fuel occurs in a confined space called a combustion chamber. ... A dynamometer, or dyno for short, is a machine used to measure torque and rotational speed (rpm) from which power produced by an engine, motor or other rotating prime mover can be calculated. ...

Driveshafts have been used on motorcycles almost as long as there have been motorcycles. As an alternative to chain and belt drives, driveshafts offer relatively maintenance-free operation and long life. A disadvantage of shaft drive on a motorcycle is that gearing is needed to turn the power 90° from the shaft to the rear wheel, losing some power in the process.

Marine driveshafts

On a power-driven ship, the driveshaft, or propeller shaft, usually connects the transmission inside the vessel directly to the propeller, passing through a stuffing box or other seal at the point it exits the hull. A propeller shaft connects a propeller to an engine. ... For other uses, see Propeller (disambiguation). ... A stuffing box (or packing gland) is a type of seal placed around a propeller shaft at the point it exits a boats hull underwater. ... A hull is the body or frame of a ship or boat. ...


As the rotating propeller pushes the vessel forward, the marine driveshaft is also subject to compression, and when going reverse, to tension. Physical compression is the result of the subjection of a material to compressive stress, resulting in reduction of volume. ... Tension is a reaction force applied by a stretched string (rope or a similar object) on the objects which stretch it. ...


Cardan shafts are also often used in marine applications between the transmission and either a propeller gearbox or waterjet.


Driveshafts in Bicycles

A shaft-driven bicycle.

The driveshaft has served as an alternative to a chain-drive in bicycles for the past century, although never becoming very popular. A shaft-driven bicycle is described as "acatane". When used on a bicycle, a driveshaft has several advantages and disadvantages: Image File history File links No higher resolution available. ... Image File history File links No higher resolution available. ... A shaft-driven bicycle. ... For other uses, see Bicycle (disambiguation). ... A shaft-driven bicycle. ...


Advantages

  • Drive system is less likely to become jammed or broken, a common problem with chain-driven bicycles
  • The use of a gear system creates a smoother and more consistent pedalling motion
  • The rider cannot become dirtied from chain grease or injured by the chain from "Chain bite", which occurs when clothing or even a body part catches between the chain and a sprocket
  • Lower maintenance than a chain system when the driveshaft is enclosed in a tube, the common convention
  • More consistent performance. Dynamic Bicycles claims that a driveshaft bicycle consistently delivers 94% efficiency, whereas a chain-driven bike can deliver anywhere from 75-97% efficiency based on condition.
  • Greater clearance: with the absence of a derailleur or other low-hanging machinery, the bicycle has nearly twice the ground clearance

Shimano XT rear derailleur on a mountain bike Derailleur gears are a variable ratio transmission system commonly used on bicycles, consisting of a chain, multiple sprockets and a mechanism to move the chain from one sprocket to another. ...

Disadvantages

  • A driveshaft system weighs more than a chain system, usually 1-2 pounds heavier
  • At optimum upkeep, a chain delivers greater efficiency
  • Many of the advantages claimed by driveshaft's proponents can be achieved on a chain-driven bicycle, such as covering the chain and gears with a metal or plastic cover
  • Use of lightweight derailleur gears with a high number of ratios is impossible, although hub gears can be used
  • Wheel removal can be complicated in some designs (as it is for some chain-driven bicycles with hub gears).
