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…
Types of Axles in Automobile Systems 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 axle is not a single piece but is in two halves…
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 center 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? 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 arranged such that when overdrive is…
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 called…

Components of a Sliding Mesh Gearbox 1. Main axis- It is the shaft used as the output shaft in a sliding link on which gear sets with internally splined grooves are neatly arranged. The outer surface of this shaft is splined so the gears can easily slide on this shaft to mesh with the appropriate…

CLUTCH FRICTION MATERIALS: The friction material acts as a coating on the surface of the clutch disc. Because they are rough, 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 (a) Fabric…

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…
