 Front & Rear Axles Shaft A n A utomobile axles shaft is a solid or tubular steel shaft that support the weight of the vehicle and transmitted torque from the differential to the drive wheel to the wheel that turns to move the vehicle. In Automobile typically, front and rear axles are used in the vehicle whether it is a light motor duty or heavy-duty vehicle. It all depends on the drivetrain of the vehicle which drives on Front-wheel drive or Rear wheel drive vehicle.  There are two types of axles shaft (i) Dead axle (ii) Live axle. Dead Axle  A dead axle is a solid axle mounted to the suspension spring with a spindle at each upon which the wheel turn. This axle does not rotate, only the wheel on the axle rotate. The axle that is used in the bullock cart is a dead axle. I-Section axle beam is the dead axle, used front axle in trucks and buses.  Live Axle  In the live axle, the axle is on which turn within a tubular housing, the axle itself rotate due to thi...

 Automobile Suspension System  The automobile/automotive suspension system is a major role play for a comfortable ride and it absorbs the full shock of the road to make passengers tireless travelling provided to us, from our vehicles. It may be any type of category of your vehicle even in two-wheelers (scooters and bike or motorcycles) and four-wheelers in light-duty vehicle cars and heavy-duty vehicles like trucks and buses. The suspension system allows the vehicle to travel over rough surfaces with a minimum of up and down body movement. Road shocks are the action resulting from the tyre moving up and down as they meet bumps or potholes in the road.  The Suspension system is located between the wheel axles and the vehicle chassis frame or body frame of the vehicles.  The main purpose of the suspension system: • Its purpose is to absorb shock and jerks and to ensure a smooth ride. • Cushion bump and hole in the road, and maintain traction between the tyres and the r...

   HISTORY OF AUTOMOBILE  / AUTOMOTIVE  We know all, the first Automobiles were horse-drawn buggies and carriages powered by the fuel-burning engine, Internal combustion (IC) Engines instead of horses. They were called motor vehicles and horseless carriages.  What do you mean by Automobile/Automotive? Auto- means self, mobile/motive means movable, thus self-movable (which can move) vehicles are called Automobiles/Automotive.  Purpose of Automobile/Automotive The automobile/automotive is a self-propelled vehicle that is used for the transportation of passengers and goods/cargo on the road. A Self-propelled vehicle is that in which power required for propulsion is produced from within like Aeroplane, ship motor ship, locomotive, car, bus, truck, tractor, scooter, motorcycle are the examples of a self-propelled vehicle. The motor vehicle is another name for a self-propelled vehicle running on the road or ground. A vehicle is a machine that is used for the tran...

  Vehicle Chassis Frame and Body The function of the chassis frame is to take the full load of the vehicle. It is a skeleton of the motor vehicle especially in heavy-duty and some light-duty cars, it must be strong enough and light in design.  The chassis frame of an automobile of following components suitable mounted and bolted: • Engine and radiator  • Transmission system, consisting of the clutch gearbox, propeller shaft, driveline and front and rear axles. • Suspension system and its related parts. • Steering system, braking system and under chassis components and parts.  • Vehicle Body, fuel Tank and battery mounting unit. In the construction of an automobile chassis frame C - section Channel chassis frame, Box type section channel, Hat section chassis frame and I - section channel chassis frame used on the heavy trucks buses and mid-light duty vehicle. Normally the various components are bolted directly to the frame  Frame   The frame is that part of ...

I  The vehicle uses for transportation from one place to another place upon the ground or road like cars, trucks & buses and on the air like a plane and in water on the ship, all these things powered by Engine fuel which made by petroleum. (Petrol & Diesel fuel). In the context of Automobiles/Automotive engines, We find Internal Combustion engines (ICE), Four-stroke cycle Engine in your vehicle. Automobile Engine   An engine is a machine that converts heat energy into mechanical energy. The heat from combustion (burning ) a fuel produces power which moves the vehicle on the road. Some time engine is also called a power plant.  Automobile engines are Internal Combustion Engine (ICE) because the fuel run them is burned internally or inside the engine. It is powered by either a Petrol engine or Diesel engine. Both engines run with a four-stroke cycle operation. May rotary engine means a rotor that spin or rotates, an engine called a Wankel design in which a three-lob...

 Flex Fuel  \ Flexible Fuel Vehicle (FFV), Duel Fuel, Flex Engine & Biofuel. The flex-fuel vehicle is as same as conventional Spark Ignition Engine Vehicles based on an internal combustion engine. Flex-fuel vehicles or dual-fuel vehicles have an engine capable of operating the functioning of dual-fuel ethanol and gasoline (petrol) with the formed mixture called blended fuel. All fuels contain ethanol to some percentage, it depends on containing ethanol and gasoline (petrol) in the blended fuels according to government policy. It mixes ethanol with other relevant fuels to make them energy productive. This flex-fuel technology is not new it was first developed in the early 1990s and used in mass production in 1994, Ford Taurus according to data of car bibles by 2017. Now there were more than a 21million flex-fuel vehicles on the road in America. Around the globe ethanol flex-fuel vehicle, approximately 60 million automobile light and heavy-duty vehicles run in the world. by ...

  Automobile Braking System An automobile braking system is a mechanical device that works at hydraulic pressure using brake fluid under pressure to the brake network in each wheel in light-duty vehicles. In modern vehicles power assist braking systems for the sake of safety and convenience also less force effort for the driver. There are several power resources used for more effective braking these are main sources engine vacuum, air, engine exhaust gases, regenerative braking and electric braking. In heavy-duty vehicles, air braking is most commonly used in trucks and buses, along with an Antilock braking system (ABS) in both heavy-duty and light-duty vehicles. Purpose and function of Braking system: Automobile brake action may be defined as the which stop any motion. Brakes are applied to slow down or stop the moving car or any vehicle. The function of the brake is to reduce the speed to stop moving vehicles within a minimum possible time and a minimum possible distance and hold...
