The document provides an overview of brakes, detailing their function as mechanical devices that prevent motion in wheeled vehicles. It outlines various types of brakes including disk, drum, hydraulic, vacuum, and air brakes, explaining their operation and specific uses. Additionally, it highlights the construction aspects and applications of each brake type in different vehicle contexts.
Brakes and its types
- 2. • What are brakes? A mechanical device Prevents motion of moving body
- 3. • Where is it used? Wheeled vehicles like cars, planes etc. Shopping carts Cycles Almost everywhere……
- 4. *Working of A Brake • Functions via forced delivered to a rotating body • Assembly with a mechanical clutch • Tightened or pressed with body to decelarate • Generate intense heat and some noise
- 5. *Types Of Brakes •Disk Brakes •Drum Brakes •Vacuum Brakes •Air Brakes •Hydraulic Brakes •Railway Brakes
- 6. *Disk brake • Uses calipers to squeeze pairs of pads against a disk • Single piston floating caliper mainly used • Main braking system in cars • Used for instant breaking • Used in cars, cycles , bikes etc.
- 7. *Construction of disk brake
- 8. *Drum Brakes • Works on the principle of disk break • Less expensive to manufacturer • More spare parts used • Useful in emergency breaking system • Located on the rear wheels • Mainly used in vehicles
- 9. *Construction of drum brake
- 10. *Hydraulic Braking *Uses brake fluid * Containing ethylene glycol, to transfer pressure to braking system *Mainly used in passenger vehicles , cars etc.
- 11. *Construction
- 12. *Vacuum Breaking • The vacuum in the brake pipe is created • Maintained by a motor-driven exhauster • Exhauster has 2 speeds Low speed High speed • Specially used in trains
- 13. *Construction
- 14. *Air Brakes • Uses air to apply brakes • Breaks are disengaged when the air tanks are full • Air fills the brake chamber, pushing the chamber diaphragm • Pushes the brake pads against the brake drum, stopping the vehicle • Used for heavier vehicles like in trucks ,aircraft etc.
- 15. *Construction
