lots of questions that need answering

Home  \  Repairs & Maintenance  \  lots of questions that need answering

ok well when i introduced myself i said i was doing a vehicle maintenance and engineering course and so i'm posting here to get help with two topics:

transmission systems and steering systems

now i tried finding stuff abt these topics on the internet but it came up with sexually transmitted dieases etc :oops: so i'm trying here.

ok question one:

List and explain the general gear classifications found in a manual transmission.

question two:

define the term gear ratio and how you would find the gear ratio of two gears.

question three:

A driver comes into your garage and reports three main faults with the gear system in his car
- oil leaks from the gearbox
- difficulty in engaging gear
- gearbox is noisy when in gear
list two possible causes of each three.

question four:

what is the formula used to dertermine the torque transmitted by a friction clutch and state the formula that is used to dertermine th horsepower transmitted by the clutch.

question five:

define the term 'transaxle' and what determines whether a conventional transmission of tansaxle is used.

question six:

what are the two functions of final drive gear and name three types of final drive. which one is used in small vehicles and state it's disadvantages.

question seven:

what is the function of a propeller-shaft, universla joint and name the two types of propeller shaft

question eight:

describe the function of the differential and when the operation action will be a disadvantage.

question nine:

mention three methods of supporting the rear axle shaft and how it is normally connected to the differential anmd what type of bearing is located between the hub and the axle casing.

question ten:

what is the main type of steering system and name four types of steering boxes in common use.

question eleven:

what is meant by
- caster angle
- comber angle (i think that's suppost to be camber though)
- king pin angle

question twelve:

before checking any steering angles or measurement what other points must be checked and mention three places on a steering column at which adjustment might be found and state the type of adjustment.

thank you in advance for taking the time to read this and answers that you have please write the question number and then write the corresponding answer

thank you very very very very much

Just read the chapter and answer them yourself. You have the book right?

that's just the poblem, i don't and i'm off school for three weeks

So little Chrissy, the real problem isn't that you can't find the answers with some effort. The real problems are that you're too irresponsible to ensure you have your study materials while on vacation and you're too lazy to do the required work to get the information. I can assure you that when you search "camber angle" or "transaxle" for example, you don't get porn sites.

Bottom line Twinkie, if you're not willing to do the work on your own, you're going to get exactly the grade you deserve. A big fat "F". Good for you.

wow good for ****ing you. you know how to rip the shit through a 16 yr old kid well done. i was looking for help and if u aren't gonna give it to me then **** off

I am trying to help you Chrissy boy. You're just too deep in denial and clueless to realize it.

How can you help someone that won't help themself ? :doh: Your'e just a dirty old man. I can't understand why you can't complete this kids lesson plan.

ding,ding,ding,DONG. You were soooooo close. 1966. Don't think there were any body/metal changes, but I have been wrong before. :thumbs:
I'll have to give it to you. I think that's fair.

This should be a snap for all the professed engineers on this forum. But I suspect the internet would overload with all the googling going on to find the answers :mrgreen: .

Will I get a deflection post = you bet I will. :laughing:

What does BOY RACER mean? I never heard of that term

Go back to first principles man .... that stuff you learn actually can mean something.

Friction force = normal force x coeff of friction
power = torque x speed

etc etc .... F = ma is the key!!!!

Okay, i've just read the rest of your questions .... I've been out of uni for a couple of years now, and doing no automotive stuff, so i can't guarantee i remember any of this properly.

1. Not sure exactly what you're after, but I assume idler gears, reversing gears .... or maybe helical / spur gears

2. Gear ratio = proportion of each others speed that 2 meshing gears turn at. Can be found in the ratio of the number of teeth, or the ratio of the radius of each gear. eg 1 gear with 40 teeth, meshing with a gear with 100 teeth - ratio 4/10 or 10/4 (0.4 or 2.5)

3. Cracked gearbox housing or cracked bearing on input or output shafts
Busted clutch or worn synchromesh
Gears misaligned or insufficient lubrication

4. see previous post, but torque is the friction force x the radius at which the force is applied. Power in W is Torque in Nm x Speed in rad/s Convert into whatever units you want.

5. ???? Judging by the name, transaxle means the gearbox is aligned with the input and output shafts at 90 degrees rather than parallel..... or possibly parallel, but at 90deg to the main drive axle.

6. Final drive is to increase torque at the wheels by running them significantly slower than if they came straight out of the gearbox. This keeps the engine revs higher than if there was no final drive.
Also, by having it separate from all of the other gears, the final drive can reduce gearbox size, as less reduction (except for longer gears) is required for each gear.

7. Prop shaft ???? Drive a propeller ????
Universal joint connects two shafts (axles) that are not parallel, but connect end to end.

8. Differential supplies equal torque to both driven wheels, but allows them to spin at different speeds. This way a car can go round corners with the inside wheel turning slower than the outside wheel, but both wheels still being driven. This is a disadvantage when one wheel loses traction and it will just spin and the other wheel won't .... the exception is a limited slip diff where the diff locks up with lack of traction, and both wheels spin together.

9. ???? Not sure what hub it's talking about, but prob either thrust or angled roller in that application.

10. Rack and pinion ..... couldn't name 4 boxes. Ball joint.

11. Can't remember the difference in all these ... I think Kingpin angle is the angle of the suspension upright, camber angle is the agle of the wheel relative to the road or the upright ... or something, I really can't remember

12. ... not exactly sure what you need to know ....

like i said ... no guarantees.
