LEARN 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, the inside wheel will turn more sharply than the outer wheel. This principle produces toe-out on turns. HOW TO TELL WHEN IT’S TIME FOR A CAR TIRE ALIGNMENT 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.

On tires, it is the fully inflated height divided by the cross-section. Read: GEAR RATIO AND TIRE SIZE CHART 4. BODY ROLL The vehicle body leaning sideways as the vehicle turns. READ: VEHICLE BODY CONSTRUCTION 5. DAMPERS Are nothing but a piston in a cylinder filled with oil or gas. The damper restrains the undesirable bounce of the sprung vehicle mass and restrains the wheel assembly from losing ground contact by being excited at its natural frequency. HOW CAR SPRINGS AND DAMPERS WORK 6. DEAD AXLE The axle does not rotate or deliver power but merely forms a base upon which wheels may be mounted.

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

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