MECHANICAL ENGINEERING TERMS 3

MECHANICAL ENGINEERING TERMS:-

1.)LEAF SPRING – A spring made up of a series of flat steel plates of graduated length, assembled one on top of another.

2.)LEVEL CONTROL (automatic) – A suspension system which compensates for variations in load in the rear of the car, positioning the rear at a predesigned level regardless of load.

3.)LIMITED SLIP DIFFERENTIAL – A differential allowing unequal torques to be delivered to the axle shafts.

4.)LINKAGE POWER STEERING – A type of power steering in which the power steering units (power cylinder and valve) are an integral part of the steering linkage.

5.)LORD LEVELING SYSTEM– A system used to level a vehicle that is heavily loaded.

6.)MECHANICAL BRAKES– Brakes operated by mechanical linkage (cables and levers) between the brake pedal and the brakes at the car wheels.

7.)METALLIC BRAKE LINING – A lining having metallic properties used to provide high temperature braking efficiency.

8.)PNEUMATIC TYRES – Tyres that are filled with air to the required pressure.

9.)POWER BOOSTER – A device used to increase the drivers brake pedal force going to the master cylinder, without an accompanying increase in pedal travel.

10.)POWER STEERING – A device that uses hydraulic pressure to multiply the drivers effort as he turns the steering wheel so that less steering effort is required.

11.)SYNCHROMESH – A device in the transmission that synchronizes gears about to be meshed so that there will not be any gear clash. Also called SYCHRONIZER.

12.)TACTILE SENSOR – A sensor that allows the vehicle operator to feel when a certain condition is reached. Disc brake pads are made to vibrate when worn to the point where replacement is necessary and this vibration is felt in the brake pedal.

13.)THROWOUT BEARING – Bearing operated by the clutch linkage used to disengage the clutch.

14.)TIE RODS – In the steering system, the rods that link the pitman arm to the steering knuckle arms.

15.)TILT STEERING WHEEL – A type of steering wheel which can be tilted at various angles, due to a flex joint in the steering shaft.

16.)TRIPLE POINT JOINT – A universal joint using bearings on three axes to maintain a constant plane of drive, making it a constant velocity joint.

17.)TUBED TYRE– Inside the tyre, there is an endless tube fitted with a valve. Air is forced through the valve and is retained inside the tube under pressure. The air acts as the cushioning medium.

18.)TUBELESS TYRE – A tyre that has the air sealed between the rim and tyre and does not use an inner tube.

19.)TWO DISC CLUTCH – A clutch having two friction discs for additional holding power used in heavy duty equipment.

20.)UNIVERSAL JOINT – The part of the drive line assembly that allows for a change in angle of the drive line as the vehicle goes over bumps.
