FIXED CALIPER TYPE DISC BRAKE-12


1-Friction pad
2-Piston
3-Rotor/Disc
4-Caliper

In this type of brake the caliper is fixed to the stub axle by the help of nut and bolts. So caliper cant be move. Both sides of caliper has fixed with pistons and friction pads. When the brake pedal presses the pressurised fluid helps to move both pistons towards the rotor. It causes the braking.

ഇതിൽ കാലിപ്പറിനെ സ്ഥിരമായിരിക്കുന്ന സ്റ്റബ് ആക്സിലിലോ മറ്റോ ബോൾട്ട് ചെയ്ത് ഉറപ്പിച്ച് നിർത്തിയിരിക്കുന്നു. ഇക്കാരണത്താൽ കാലിപ്പറിന് ചലിക്കുവാനുള്ള കഴിവ് ഉണ്ടായിരിക്കില്ല. കാലിപ്പറിന്റെ ഇരുവശങ്ങളിലും രണ്ട് പിസ്റ്റണുകളും അതുമായി ബന്ധപ്പെടുത്തി നിർത്തിയിരി ക്കുന്ന ഫ്രിക്ഷൻ പാഡുകളുമുണ്ട്. ബ്രക്ക് പെഡൽ അമർത്തുമ്പോൾ പമ്പ് ചെയ്യപ്പെടുന്ന ഫ്ളൂയിഡ് കാലിപ്പറിന്റെ ഇരുവശങ്ങളിലുമുള്ള പിസ്റ്റ്ണുകളുടെ പുറകിൽ എത്തുകയും, പിസ്റ്റണിനെ മുന്നിലേക്ക് തള്ളുകയും ചെയ്യുന്നു. ഈ അവസരത്തിൽ ഡിസ്കിന്റെ ഇരുവശങ്ങളിലും ഫിക്ഷൻ പാഡുകൾ അമരുകയും ബ്രേക്ക് സംജാതമാകുകയും ചെയ്യുന്നു.

INTRODUCTION TO ENGINE

Engine : It acts as the power unit. The internal combustion engine is the most commonly used in automobiles. It is of two types ; (i) Spark ignition (ii) Compression ignition.         Both engines are called heat engines. A steam engine is an external combustion engine because the fuel is burned outside the engine. The principle of working of an external combustion engine is shown in the figure below. COMPARISON BETWEEN INTERNAL AND EXTERNAL COMBUSTION ENGINES      The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the pistons and by moving it over a distance, generate useful mechanical energy.          The internal combustion engine...

FOUR STROKE SPARK IGNITION (PETROL) ENGINE

FOUR STROKE PETROL ENGINE MAIN PARTS 1. PISTON 2. CYLINDER 3. CONNECTING ROD 4. INLET VALVE 5. EXHAUST VALVE 6. SPARK PLUG 7. CRANK SHAFT 8. FLY WHEEL 9. CAM SHAFT CONSTRUCTION A four stroke petrol engine have a piston, connecting rod, crank shaft, inlet valve, exhaust valve and a spark plug. The connecting rod is used to connect the piston and crank shaft. The spark plug and valves are mounted in the cylinder head. Also the valves are operated by cam shaft which is connected to the crank. In this type of engines, there would be a power stroke for every two rotations of crank shaft. It is also known as otto cycle. Each full rotation of crank having two strokes. So one stroke is  180° rotation of flywheel. A four stroke petrol engine having the following strokes. WORKING Induction stroke : The crankshaft moves the piston downwards (TDC to BDC). The inlet valve is open and a mixture of fuel and air is sucked into the combustion chamber. It is also known suction stroke. In this strok...

MAJOR PARTS OF AN IC ENGINE

ENGINE COMPONENTS 1. CYLINDER BLOCK      The cylinder block is the main body of the engine. Cylinder head is mounted on the cylinder block. It houses iniet and exhaus valves. Crank case is attached to the bottom of the cylinder block. Crank case supports the crank shaft. Oil pan is attached to the bottom of the crank case. Cylinder block contains large cylindrical holes called cylinder bore. The cylinders are accurately finished to accommodate pistons. The space above the piston inside the cylinder at TDC called the combustion chamber. Combustion of fuel inside this space, high pressure and temperature will be developed inside the cylinder. Therefore, it should be made of material which can resist high pressure and temperature (2800°C). In water jackets has around the cylinders for the circulation cooling water to absorb the temperature while running of an engine. 2. CYLINDER HEAD Cylinder head is a separate casting placed on top of the cylinder block by studs and nuts. I...
