The master cylinder is the main component of the system. When the brake pedal is depressed, fluid in the brake master cylinder, under pressure, flows out of it and into the fluid lines leading to the wheel cylinders. It is divided into two parts, namely, fluid reservoir and compression chamber. When the pedal is depressed,…
Brakes operated by hydraulic pressure (fluid pressure) are called hydraulic brakes. Hydraulic brakes are commonly used in automobiles. Principle Hydraulic brakes work according to the principle of Pascal’s law, which states that “the pressure at one point in a fluid is the same in all directions in space”. According to this law, when pressure is…

Mechanical brakes Mechanical brakes are sets that consist of mechanical elements for the deceleration or stop of axes in equipment drives. They use levers or links to transmit force from one point to another. Braking slows or stops the movement of the coupled axes. There are several types of mechanical brakes. Band brakes, the simplest…
Differential used in Automobile cars & Trucks Above Figure. Shows the key parts of the type of differential used in rear-wheel-drive cars.A smaller bevel gear called a differential side gear is mounted on the inner ends of each shaft. Two bevel gears are mounted to mesh the driven and driven shafts at a 90 °…
Gears are a crucial part of many automobile vehicles. Gears help increase delivered torque by providing a reduction in gear and adjusting the direction of rotation like the axle of the rear wheels of motor vehicles. Following are some basic types of gears & how they differ from each other. Spur gears in Types of…
Following are the three different types of axles in Automobile Systems Rear Axles Front Axle Stub Axle Rear Axle in Automobile Between the differential and the drive wheels is the rear axle to transmit the power from the differential to the drive wheels. It is clear from the construction of the differential that the rear…
Propeller shaft: Movement from the gearbox is transferred to the differential which is the next component of the transmission system. The differential is located in the centre of the rear axle and the vehicle is rear-wheel drive. Alternatively, the vehicle can be a front-wheel-drive or, in some cases, engine motion can be transferred to both…
1. Noisy gearbox operation: • The bearings may be worn, in which case they will need to be replaced. • The countershaft can be worn, bent or have a large axial play. This must be replaced with a new countershaft. • Constant-mesh gears can be worn. The only alternative is their replacement. • Lack or…

A torque converter is a type of hydraulic coupling used to transfer rotating power from a vehicle’s engine to the transmission. Replaces a mechanical clutch in an automatic transmission. The torque converter is a type of hydraulic coupling used to transmit more torque to the shaft driven by a prime mover such as an engine….
What is Overdrive in Automobile Engineering Introduction to Overdrive An Overdrive is a component of a transmission system that is connected to the end of the gearbox to provide maximum driving power with minimum engine input which in turn makes for a smoother and more fuel-efficient ride. It is a planetary and planetary gear arrangement…
This is a manually operated transmission in which transmission changes occur between gears rotating at the same speed. The gears can roll freely or can be locked onto the layout shaft in this type of gearbox. Synchromesh Gear Box Construction: The synchronizer is positioned between two gears. So, we can use a unit for two…
Constant Mesh Gearbox was invented to push the boundaries of the sliding mesh gearbox. In this gearbox, all gears are always in gear. The gear stays fixed and does not slide like the sliding link gearbox. In this gearbox, the sliding link was replaced by gear pairs that constantly mesh and new gear shifting devices…
WHAT IS A GEARBOX? The gearbox is a mechanical device used to increase the output torque or to change the speed (RPM) of a motor. The shaft of the motor is connected to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed…
CLUTCH FRICTION MATERIALS: The friction material acts as a coating on the surface of the clutch disc. Because they are rough in nature, they offer a higher coefficient of friction—a higher coefficient of friction results in greater frictional force and better motion transfer. There are two types: (a) Woven friction material (b) Molded friction material…
Automobile Clutch In automobiles, power is developed by the engine that is used to turn the wheels. Therefore, the engine must be connected to the transmission systems to transfer power to the wheels. In addition, there must be a system that allows the engine to be engaged and disengaged from the transmission system smoothly and…
