Mid term

Question 1

stright spur gears

Answer 1

cheap, noisy, balanced, weak

Question 2

Helical Spur

Answer 2

More expensive, Stronger, Less Noisy, unballanced, generate side loads

Question 3

Hering Bone

Answer 3

Rare, Strong, Less Noisy, Tractor Trade, Ballanced

Question 4

Bevel Pinions

Answer 4

Allow the speeding slowing of each axel to speed up or slow down independtly

Question 5

Plain Bevel

Answer 5

Stright Teeth

Question 6

Spiral Bevel

Answer 6

Most common, similar advantages as the hylical gear

Question 7

Hypoid Bevel

Answer 7

allows engine and transmission to be lower than the axel

Question 8

Cone Clutch

Answer 8

Two tapered matching, tighter the grip the further they are pushed together

Question 9

Expanding shoe clutch

Answer 9

Tranmits power when its two ends are pushed out apart from eachother as far as possible

Question 10

Over Center

Answer 10

This style of clutch hold itself in both engaged and disenagaged positions so the operator does not need to hold in on the clutch pedal for either prosition

Question 11

Centricuigual Clutch

Answer 11

This clutch is designed to grab and transmit power when the engine speeds is increased and then disengaged when teh engine speed is decreased

Question 12

Band Clutch

Answer 12

connecting the inner rotating member to an outer one by claming the outer one onto the inner one with the linkage.

Question 13

Magnetic Clutch

Answer 13

activated by the operator from a switch sending current to a large coil of wire

Question 14

Slip Clutch

Answer 14

This clutch will allow the drive side to continue to rotate after an excessive load is placed on the driven side

Question 15

Over Running Clutch

Answer 15

Prevents the driven side from comming to a rapid stop when the input side is stoped.

Question 16

Live PTO

Answer 16

The Clutch involves only one throw out bearing but has two seperate clutch discs

Question 17

Independent PTO

Answer 17

Involves two though out bearings one for each set of clutch discs

Question 18

Torque Converter input

Answer 18

Impeller

Question 19

Turbine

Answer 19

drives the tranmission

Question 20

Stator

Answer 20

Redirects oil flow back into the pump

Question 21

Vortex Flow

Answer 21

Oil flow is turbulent and powerful, occurs during a torque converter stall

Question 22

Rotary

Answer 22

Oil flow when the input and output speed match

Question 23

Most stators

Answer 23

are allowed to free wheel during rotary flow

Question 24

Lock-Up Converter

Answer 24

Mechanically connects input and output at cruise speeds

Question 25

Torque Converter stall

Answer 25

When the engine is at WOT and the torque converter is stopped

Question 26

Diff Lock

Answer 26

usually locks one axel shaft to the differential housing.

Question 27

Hydraulic Diff Lock

Answer 27

discs are splined to a bevel gear to the axel drive. plates get tanged to differential housing

Question 28

Auto Locker

Answer 28

over running camaction that. Allows the outer wheel to break free from the rest of the machine. Prevents slower wheel from breaking free, thus allowing positive traction.

Question 29

Limited Slip

Answer 29

Basic differential housing except the bevel gears are allowed to flow on the shaft just a few millimeters.

Question 30

Pourpose of Cone point adjustment

Answer 30

to corrrectly set the relation of ring gear and the pinion gear with a precise shim pack.

Question 31

Pourpose of Final drives

Answer 31

To reduce the torque load on the tranmission. Also creates a higher torque to the ground and allows the tranmission to be smaller.

Question 32

Axels

Answer 32

Most cases the axels are semi float axels meaning that the axel shaft is supported by bearings that are pressed on the axel housing

Question 33

Full Floating axels

Answer 33

Bearing located between the axel housing and wheel hub. Axel shaft only has to be hold the torque.

Question 34

Pinion Style Gear Reduction

Answer 34

gear is driven off the differential bevel side gear that is splined to the axel shaft.

Question 35

Planetary drive

Answer 35

load is spread over 3x as many gears as pinion, ballanced no side loads, uses same lube as differential, usually attached to a rack and pinion style axel shaft.

Question 36

Outboard Planetaries

Answer 36

Planetary is located inside the wheel hub, has a seperate oil supply from the diffrential oil.
