drive
In technology , a drive is used to describe the structural unit that moves a machine by means of energy conversion . Often this is a motor with a possibly necessary gear . There are rotary actuators and linear actuators. Non-mechanical objects such as draft animals , wind , flowing or falling water and manual drive by humans are also to be regarded as primary drives .
The output is the part that is available for use by the drive unit. Often a coupling separates the drive and output side. If you look at the machine on the output side of a system, you also speak of a working machine , while the driving side is referred to as the power machine .
The devices for driving a device often use several different operating principles whose carriers are coupled. Combustion energy is used in a diesel engine for a truck , which is applied according to the principle of the piston engine and the crank drive and transfers the rotary motion to the wheels . The truck is thus correctly designated both as a "vehicle with internal combustion engine" and as a "vehicle with wheel drive".
Designation of the drive types
According to the primary energy source
- Drive with muscle - power
- Foot drive ( treadmill (pedal) roller , pedal )
- Hand drive ( hand crank , hand wheel , corrugated wheel, etc.)
- Drive by animals ( Göpel , Wellrad )
- Wind power drive
- Hydropower propulsion
- Combustion power drive , thermal power drive
- Gravity drive (watch weight)
- Spring mechanism drive
- Solar propulsion
- Atomic energy propulsion
- Electric propulsion (this also includes ion propulsion )
- Hybrid drive (combustion engine + electric motor )

According to the implementation principle
- Motor drive
- Hydraulic drive
- pneumatic drive
- Rocket propulsion
- Turbine drive
- Sail drive
- Sheave , belt , friction wheel drive
After the construction part at the end of the implementation chain
- Direct drive
- Wheel drive (see also single wheel drive )
- Paddle wheel drive
- Gear -drive: see also gear

Belt drive
- Toothed belt drive
- V-belt drive
- in rail vehicles
- Threaded spindle drive, ball screw drive , roller screw drive , worm drive (see linear technology : drive systems)
- Crawler drive (tracked vehicle)
- Propeller drive
- Recoil drive
According to the goal of the drive
- Power transmission (e.g. drive a generator )
- Change of location
- Positioning drive; defined change of position (see also linear technology )
- Material drive ( vibratory conveyor , conveyor belt , screw conveyor , hose pump , pneumatic tube )
- Vehicle propulsion, transport ( aviation propulsion )
According to the type of movement
- Linear drive (see linear technology )
- rotation
- Vibration (vibrating armature drive )
