Today we started by striping down the automatic transmission and identifying some of the components:
***Note: there is further description of the parts on "DAY 2"
DAY 2:
Today we discussed what the purpose of a torque converter is and its purpose and eight major components of the automatic engine is:
1.Torque converter: transfer's torque from the engine to the transmission and multiplies torque
2. oil pump: supplies oil to the transmission system
3. Planetary gears: supplies power flow through the transmission
4. Input shaft: provides power from the engine and prevents slippage
5. Output shaft: supplies the wheels with power
6. Governor: sence's the speed the vehicle is travelling and the throttle percentage
8. Transmission screen: filter's the transmission fluid
DAY 3
Today we describe what a servo does in a auto transmission, describe 2 advantages of a lock up torque converter and re-assembled our rear wheel drive transmission, The servo in the transmission holds the bands or controls the bands.
The 2 advantages of using a lock up torque converter are, 1. they get 2% more power due to less slippage
2. increase the fuel economy 2% at mid power with low throttle
Day 4: Today Myself, James and Jiejun dis-assembled a front-wheel drive trans-axel automatic gear box to look at how it works
And compare it to the previous rear wheel drive gear box
We went through components in there various positions in the trans axel such as the valve body (this has a vacume system to determine throttle position
In the bell housing we can see the various shafts, the oil pump, stator and input shafts
The oil pump her is run from a shaft that runs through the transmission from the torque converter
The image below is of the transmission housing after the clutch packs and planetary gears are removed
The governer on this transaxel is on the side of it as appose to the rear wheel drive governer which runs on the shaft
This is the innerts of the transmission with the clutch packs and planetary gears ect,
After this Myself, James and Jiejun proceeded to re assemble the transaxel gearbox.
Hi Cody, i have sorted the gremlins so have now started to look over Auto Transmissions.It would be good to see an explanation of the components described and how they work and what they do in the Auto Trans,like the Governor and Planetary gear set.Maybe describe what kind of Plant gear set was in this Auto Trans.Just a matter of interest is there any work and progress on Manual Transaxles which is also pert of the criteria as part of 4844.Keep up the work.
ReplyDeleteHi Cody,i see you are providing some theory behind the components of the Auto Transmission mainly the Jatco with reference to the Governor and the oil pump and its connection with the Torque converter,so which component in the converter would that be as one represents the driving member as the other is driven.I am not sure that is clear as i cannot see that identified.It looks to me as though you are doing some good work so keep it up,good on you.
