Industrial Transmission Systems Hydraulics
We will • Look at the basic concepts of hydraulic operation • Evaluate hydraulic systems in comparison to other systems • Look at where hydraulic control is used within an automotive context • Look at transmission systems in a wider context
What do we need to transmit? • Signals • Force • Energy • Data • Momentum • etc
How can we transmit? • Wireless • Wired • Hydraulic • Pneumatic • Levers and pulleys • Optical • Electrical
Task: • Where do we find Hydraulic systems in everyday life? • Why do we use hydraulics for power transfer? • What medium is used for hydraulics?
Hydraulic Transmission • Pascal's law is the basis of hydraulic drive systems. As the pressure in the system is the same, the force that the fluid gives to the surroundings is therefore equal to pressure × area. • In such a way, a small piston feels a small force and a large piston feels a large force.
Task: • Where do we find hydraulic systems in a car? • Brake system • Steering • Fuel injection • Hydraulic transmission • Clutch possibly • Automatic transmission • Fuel pump • Hydraulic Drive transmission • Hybrid cars for energy conservation • Shock absorbers
