Differential basics

Steering axles are usually _______

____________type. They support the vehicle weight through the ________________________________ and allow the vehicle to be turned.

• I-beam, front suspension

• flat, no suspensions

• round, all suspensions

• J-beam, rear suspension

Drive axle (or live axle) contain the ____________ necessary to ___________ the vehicle.

• gearing, stop

• weariing, drive

• gearing, drive

• fire, truck

A tridem is:

• two drive axles splitting the driving force

• four drive axles splitting the driving force

• three drive axles splitting the driving force

• Posiden's Trident splitting the driving force

The _____________ axle, can be raised or lowered.

• puller

• pusher

• split

• overslung

The wheel on the__________________of an axle has to travel further than the wheel on the ____________________during a turn.

• inside , outside

• outside, inside

• upside, inside

• inside, downside

The primary function of a drive (live) axle is to:

• allow the rotational power to turn 360 degrees.

• allow the rotational power to turn 180 degrees.

• allow the rotational power to turn 45 degrees

• allow the rotational power to turn 90 degrees.

The secondary function of the differential is to:

• allow for speed differences between the two axle shafts of the drive axle when turning.

• allow for speed differences between the two axle shafts of the front axle when turning.

• allow for speed differences between the two axle shafts of the tag axle when turning.

• allow for no speed differences between the two axle shafts of the drive axle when turning.

A worm mounted above the crown wheel is called ______________________________.

• square mount

• overslung mount

• top-mount

• side- mount

In a hypoid gear set, the pinion is mounted _______________ the centerline of the crown gear

• inside

• around

• beside

• below

___________________ _____________________topoid system places the pinion higher on the ring gear than an amboid system.

• Cummins'

• Mack's

• Detroit Deisel’s

• Kenworth's
