Propeller Shaft & Drive Shaft
Drive shafts must therefore be strong enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia. 2.8.1 Role of Propeller Shaft The torque from the engine is to be transmitted to the rear wheels for propelling vehicle. The drive shaft must provide a smooth, uninterrupted flow…

Manual & Automatic Transmission System
Stages Fully depressed Clutch: The clutch is completely disengaged during the full depression stage and no torque is transmitted. Clutch slips: The clutch slip allows the engine rotation to adjust to the newly selected gear ratio gradually. Released Clutch: Torque will be transmitted to the transmission. Automatic Transmission System This advanced transmission system is composed…

Differential Gear Box
Input torque is sent to the ring gear and then to carrier. The carrier gear is connected to both the side gears by the planet gear. The planet gear revolves driving the side gears. Torque to the Propeller shaft is supplied by transmission line. A bevel gear takes drive from propeller shaft, and is encased…

Synchromesh Gear Box
The arrangement are the same as constant mesh type gear box. Gears on the main shaft mesh with those on lay shaft. The gears on the lay shaft are fixed. This provision avoids the need for double declutching. Figure 2.7 shows design of a synchromesh gear box. These devices reduce the cost. Gears B, C, D, E in Figure…

Transmission System
Introduction The transmission helps to transmit power from the engine to the wheels. It consists of gears, shafts, and other electrical connections. It is composed of systems shown in Figure 2.1: 2.2 Clutch This part is used to engage and disengage the engine from drive. It allows the driver to control the power flow between the…

Characteristics of Ground Vehicle
The main aim of studying the mechanics of vehicles is to gain the ability to establish rules for the development, design, and selection of vehicles. Performance means the ability of the vehicle to accelerate, overcome obstacles and to stop. Handling is concerned with the driver’s response to the vehicle. Ride is related to the vibrations…

Functions of Subunits
Mechanical energy is converted into Motion. Any Automobile consists of Power-train and Non-Power-train components. Power-Train components parts involved in the process of generating power to converting it to motion. Non-Power-Train components parts includes Body, Frame and Steering. Parts of Automobile Systems Drive train indicates the power flow of motor vehicle from engine to driving wheels.…

Introduction
Classification of Motor Vehicle Motor Vehicles are used for transporting goods or passengers or fulfilling specific functions on land. Motor vehicles can move on the ground, as compared to aircraft and marine craft that operate in air or water. Based on Type of Roads Moped – Motor cycle with pedals and a petrol engine of…

Fast Fourier Transform Analysis
Although equipment for analyzing noise and vibration signals with constant frequency bandwidth filters and constant percentage bandwidth (CPB) filters are still available, these instruments have largely been replaced by Fast Fourier Transform (FFT) Digital Fourier analyzers. These types of analyzers give similar results in a fraction of the time and at a lower cost. These Fourier analyzers are manufactured…
