INTRODUCTION: Different layouts with reference to power plant, location and drive. (2) DESIGN OF FRAME: Types of frames, various forces acting on frames, different sections, materials, crash safety. (3) DESIGN OF AXLES: Purpose of axle settings, wheel base and track. Front axle - functions, forces acting, cross sections. Rear axles – functions, forces acting, different types and design, simple design calculations. (5) DESIGN OF STEERING SYSTEM: Functions, requirements, conditions for true rolling – Ackerman and Davis mechanisms, roll centre and roll axis. Steering geometry – camber, castor, king pin inclination, toein, toe out, steering angle and steering ratio. Steering gear boxes- recirculating ball, worm and worm wheel, rack and pinion. Steering linkages, steering kinematics. (8) DESIGN OF SUSPENSION SYSTEM: Types of suspension, factors affecting ride quality, suspension springs. Shock absorbers, different suspension systems, suspension spring design, gyroscopic effects. (7) DESIGN OF BRAKING SYSTEM: Function, stopping time and distance, weight transfer during braking, brake actuating mechanisms – mechanical, hydraulic and pneumatic, disc and drum brakes - design and analysis of brake shoes and friction pads. (10) SELECTION OF WHEELS AND TYRES: Tyre requirements, selection of tyres, wheels and mountings – lateral force and friction co-efficient, self aligning torque and caster offset, overturning moment, torque steer effects.
