Transmission system 2 In this session, we shall discuss the axle, which transmits power to the wheel. It plays a crucial role in the movement of a vehicle. Propeller Shaft. This is a shaft which transmits power from an engine to the wheels of a motor vehicle. It is a hollow tubular shaft and consists of mainly three parts 1. Shaft: It mainly bears torsional stress produced due to twisting. It is usually made of tubular cross section. 2. Universal joints: One or two universal joints are used, depending on the type of rear axle drive used. The universal joints help in the up and down movements of the rear axle when the vehicle is in running condition. 3. Slip joint: Depending on the type of drive, one slip joint may be there in the shaft. This serves to adjust the length of the propeller shaft when demanded by the rear axle movements. Front and Rear Axle Front axle Front axle carries the weight of the front portion of the automobile as well as facilitates steering and ...

Transmission system Transmission System Transmission system is used in motor vehicles to supply the output of the internal combustion engine to the drive wheels. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmission system consist of Clutch assembly Gear box assembly (Transmission case assembly) Propeller shaft Clutch system The clutch assembly interrupts the power flow between the engine and the transmission when the vehicle is brought to a stop with the engine running. and when shifting gears. It is a mechanical device that transfers all power from the engine into the transmission of a vehicle. Without a properly operating clutch, power transfer and gear shifting would be very difficult. The clutch is located between the engine flywheel and the transmission Functions of Clutch (a) To disconnect the engine power from the gear box as required. (b) To allow the engine to take up load gradually without...

Engine component II Crank and Crankshaft The crankshaft is called the backbone of an engine because it converts the reciprocating motion of piston into the rotary motion of the crankshaft. The crankshaft is a single casted unit and is made of drop-forged steel main journals which are placed and supported in the crank case. The main journal and connecting journals are machined to a smooth finish to reduce friction and shell bearings are used for smooth rotation of crankshaft. Front end of the crankshaft will transmit drive to the camshaft and also to the timing gear, whereas the flywheel is bolted to the flange at rear end of the crankshaft. Main journal of the crankshaft carries the oil passages to lubricate shell bearings. In case of a single cylinder engine crank assembly is used, two crank webs are connected with the crank pin, and crank webs shafts are press fitted in both. At one side of the shaft magneto is fastened whereas clutch assembly is mounted to the other. The crank ...

Engine Component Cylinder block The cylinder block, which consist of a cylinder liner single casted unit and is considered to be the main body of an engine. In which the piston reciprocates up and down from Top Dead Centre (TDC) to Bottom Dead Centre (BDC) to generate power. The cylinder block and cylinder liner are fabricated to withstand high pressure and Temperature during the power stroke. The cylinder block is well-designed with water passages to remove the excess heat and separate oil passages are provided for the circulation of lubricating oil. The top portion of the cylinder block is covered by the cylinder head. The crankcase is an integral part of the cylinder block which houses the crankshaft and the lower portion is dipped in an oil pan.

The power house of your car is the Engine, it's able to give the vehicle the needed power to get the vehicle working. Engine burns fuel and air to produce power or energy. There are different processes of fuel combustion. When the fuel is burned within the engine, it is called an Internal Combustion (IC) engine, and when it is burned externally and the produced steam is used for the mechanical movement, it is called an External Combustion (EC) engine. Internal combustion Engine: this is the engine used by our vehicles (cars,trucks etc) and it has a 2 major engine type which are the spark ignition and compression ignition engine. The spark ignition engine can be differentiated from the compression ignition engine as per the following factors. (i) The type of fuel used. (ii) The way the fuel enters in the combustion chamber. (iii) The way in which fuel is ignited. Spark Ignition Engine (Petrol or Gas Engine) In the spark engine, air and fuel enters into the combustio...

Imagine you driving or board a cab/bus and you enter into a bump or a pothole, and just didn't feel it, (like nothing happen) that is the work of a good suspension system, and just think otherwise, awwwww your guess is as good as mine. We will take a brief look into the suspension system in today's post Suspension system: Suspension refers to the use of front and rear springs to suspend a vehicle’s frame, body, engine & power train above the wheels. Functions of suspension system The main functions of a suspension system are as follows: 1. To safeguard the occupants against road shocks and provide riding comfort. 2. To minimise the effects of stresses due to road shocks on the mechanism of the motor vehicle and provide a cushioning effect. 3. To keep the body perfectly in level while travelling over rough uneven ground, i.e., the up and down movement of the wheels should be relative to the body. 4. To isolate the structure of the vehicle from shock loading an...

What is an SUV? Hey TTB followers, welcome to Autocare with Damilare Today we'll look at SUVs, and its importance. Quite many but few points will be discussed here. SUV stands for Sports Utility Vehicle. They are bigger and taller than normal cars by having a higher roof and seating position which gives the driver a better view of the road ahead. An SUV also has a raised ground clearance to make driving over rugged terrain easier. You can also get more compact SUVs, which are known as crossovers. SUV needed to have four-wheel drive, which helps prevent it getting stuck on slippery surfaces. However, bear in mind that some SUVs don't, in order to reduce weight and improve fuel economy. An SUV is also tall. The original purpose wasn't to give the driver a better view of the road ahead, but to enable the vehicle to pass over jagged rocks, and through ruts, without scraping the bottom. It's got lots of interior space too. Whether you're an extreme sports e...
