TECHNICAL TERMS OF AUTOMOBILE ENGINEERING !!


1.)ACKERMAN PRINCIPLE – Steering geometry in which the outer ends of the steering arms are bend slightly inward so that when the vehicle is making a turn, inside wheel will turn more sharply than the outer wheel.This principle produces toe out on turns.

2.)AIR BLEEDER – A device used to remove air from a hydraulic system.Types include a needle valve, capillary tubing to the reservoir, and a bleed plug.

3.)ASPECT RATIO– The ratio of the width to the length. On tyres, it is the fully inflated height divided by the cross section.

4.)BODY ROLL – The vehicle body leaning sideways as the vehicle turns

5.)DAMPERS– are nothing but a piston in a cylinder filled with oil or gas.The damper restrains undesirable bounce of the sprung vehicle mass and restrains the wheel assembly from loosing ground contact by being excited at its natural frequency.

6.)DEAD AXLE – Axle that does not rotate or deliver power but merely forms a base upon which wheels may be mounted.

7.)FLOATING CALIPER DISC BRAKES – Disc brakes using a caliper mounted through rubber bushings which permit the caliper to float, or move, when the brakes are applied.

8.)MASTER CYLINDER– The liquid filled cylinder in the hydraulic braking system where hydraulic pressure is developed by depression of the brake pedal or movement of the brake lever.

9.)OVER STEER – The tendency of a vehicle to turn sharper than the turn selected by the driver.

10.)PROPELLER SHAFT – A shaft in the power train that extends from the transmission to the differential and transmits power from one to the other.
